★ 大纲规定的单元日常核心交际用语指南
Suggestions (建议)
以建议或者劝告的形式要某人做一件事，不同于直接命令，因为说话人只是提出建议，而把做与不做的决定权留给听话人。选择表达法时需要考虑建议之事的难度及交际双方的关系。事情的难度越大，两者的关系越远，表达法则越需要客气。

★ 单元核心句型剖析
1. ( Lesson 45 ) 在对话中有这样一句：What do you find hardest in English ? 你觉得学英语最难的是什么 ？
〖剖析〗本句是 find 的复合结构。hardest = the most difficult 作宾补。又如：
He found it impossible to see her .
能作 find 的复合宾语的有：名词、现在分词、过去分词、副词、介词、形容词、to be 。
We found it a difficult problem to answer .
She found him waiting for her in front of the office .
We find this county greatly changed .
We entered her house ,but found her out .
We find these children at play .
I found the singer to be a girl of 7 years of age .
2. ( Lesson 45 ) The more you listen to English , the easier it becomes . 英语听得越多，它就越容易懂。
〖剖析〗(1)“The + 比较级 (从句) ，the + 比较级 (主句)”结构相当于汉语的“越是……，越是……”，前部是主句，后部是从句。在这种结构中，比较级词可以一样，也可以不一样，可以是形容词或者副词，成递进或者递减。如：
The more you practise , the more you know .
The busier he is , the happier he feels .
The sooner you do it , the better it will be .
(2) 在时态上，如果主句为将来时，从句可以用现在时代替将来时。并且，句子常省去相同的成分。例如；
The more you get together , the happier you will be .
The less said about it , the better . 少说为佳。
The more haste , the less speed . 欲速则不达。
3. ( Lesson 46 ) If you do have difficulties , it is better to try once more another day . 如果确实有困难，最好改天再试试。
〖剖析〗此句中的 do 是助动词起加强语气的作用。要注意 do 随着主语的变化而变化。该结构还何以用于祈使句的前面。如：
She does look nice today .
I did meet her in the street yesterday .
Do have another cup of coffee !
Do be a good boy !
4. ( Lesson 46 ) They are of great help to learners of English . 它们对英语学习的人来说大有帮助。
〖剖析〗“of + 抽象名词”表示主语的性质及属性。该结构可以转换为抽象名词的形容词。如：
It is of great help to read such a book . = It is very useful to read such a book .
注意该句型的名词前可以使用表示程度的 little , some , a bit , much , no 等。如：
What he will buy her is of little use . 他给她买什么都用处不大。

Love Letters
Jenny Gordon was a very kind and beautiful woman and before she married , many men were in love with her . Many of them wrote to her , telling her how wonderful she was , how much they loved her and wanted to marry her .
Jenny kept all these letters . She tied them up with a red ribbon and put them away in an old box . She never looked at them as she was happily married , however , they were a part of her life and she didn't want to throw them away .
Jenny had a daughter , Sue . Sue was a six-year-old girl .
One day , Jenny had to leave Sue alone for half a day . “Now be a good girl ,”she said . “Play quietly . If you need anything , go to the lady next door . ”
When she returned home , she asked Sue , “Have you been a good girl ?”
“Oh , yes , Mommy , ”Sue said .
“What did you do while I was out ?”Jenny asked her .
“I played mailman , ”Sue told her .
“How could you play mailman , darling ?”Jenny asked her .
“You didn't have any letters .”
“Oh , yes I did , Mommy , ”Sue said . “I found some in an old box upstairs . They were tied up with a red ribbon . I put one in every mailbox in the street . Wasn't I a good girl ?”
〖赏析〗通过阅读全文可以知道是Sue 好奇地把妈妈收藏的爱情之信一一投进别人的邮箱。这下子可就要沸腾了。当Jenny Gordon 听到女儿那天真、可爱的当了邮递员的回答时，她过去的一切前被暴了光，她可能五雷轰顶，也可能哭笑不得。

THE HOUNDS OF BASKERVILLES (猎犬)
柯南道尔 著
Chapter XIII
EXTRACTS FROM THE DIARY OF DR . WASTON
( 华生医师日记摘录 )
Here are some extracts (摘录) from the diary of Dr. Waston . From them the readers will learn of the events that happened after his last report to Sherlock Holmes .
October 16th . A dull and rainy day . The house is as unpleasant as the weather . Everything is gloomy around and I myself have a feeling that there is danger here , though I cannot guess from where it comes . I certainly don't believe in anything that has something to do with God , but facts are facts and there is something very strange about the moor .
Twice with my own ears I have heard a sound which was like the distant barking of a dog . But if there is a hound on the moor , where is it hidden ? Where does it get its food ? Another strange thing is this unknown man on the rock . He is not one of those whom I have seen here and I have now seen all the neighbours . Is he a friend or an enemy ? Is it possible that he is the man who followed Sir Henry in London ? If only I could find out who he is !
This morning there was a small scene after breakfast . Barrymore said that we had no right to hunt down Selden after Mrs. Barrymore had told us of her brother's hiding-place .
“The man is dangerous ,” answered Sir Henry . “You know that there are some lonely houses on the moor . It is necessary to let the police know where he is .”
“Please , sir , don't call the police . I promise that he will not attack anybody . In two or three days he will be on his way to South America and will never trouble anyone again . ” Begged Barrymore .
He begged so hard for the sake of his poor wife that Sir Henry agreed not to let the police know anything about Selden . Barrymore thanked him and turned to go, but then hesitated and came back .
“ You have been so kind to us , sir , that I want to tell you something which maybe has something to do with the death of Sir Charles . I have spoken to no one about it yet .”
We both jumped to our feet .
“ Do you know how he died ? ”
“ No , sir. But I know why he was at the gate that night . He had to meet a woman there . I don't know her name , but I can give you the initials (姓名的开头字母) . They are L.L.”
“ How do you know this , Barrymore ? ”
“ Well , Sir Henry , your uncle got a letter that morning . It was addressed in a woman's hand . I didn't think of this letter at the time , for Sir Charles usually got many letters . But only a few weeks ago my wife was cleaning Sir Charles' study and she found the ashes of a burned letter in his study . The greater part of it was burned , but one little bit remained and the writing could still be recognised . It said:‘please , please , burn this letter , and be at the gate by ten o'clock . L. L.’”
“ Have you got this bit of the letter ? ”
“ No , sir, it crumpled (易碎的) all to bits after we had touched it .”
“I cannot understand , Barrymore , why did you not speak about it before .”
“ Well , sir , on one hand , we had our own trouble with Selden at that time , on the other hand , we both loved Sir Charles and thought it would be better not to tell anybody that there was a lady in the case . But now , sir , you have been kind to us , and I feel that I must tell you all I know about it .”
When Barrymore had gone , Sir Henry turned to me .
“ Well , Waston , what do you think we must do ? ”
“ I shall report to Holmes at once . Maybe he will come here himself .”
October 17th. It has been raining all day . In the evening I put on my raincoat and went for a walk on the moor . I wanted to see the rock where the stranger had stood that night . All was silent there and I could not find any trace of the unknown man . As I was walking back , I was overtaken by Dr. Mortimer driving home in his dog-cat . He was returning from one of the distant farms . He invited me into his cart and told me that he was very much troubled , for his little spaniel had disappeared on the moor . I thought of the dreadful Grimpen Mire and said nothing .
“By the way , Mortimer , ”I asked a little later , “I suppose you know all the people on the moor .”
“I think so .”
“ Do you know any woman in the neighbourhood whose initials are L.L.? ”
“He thought a little and then said that it probably was Laura Lyons the daughter of Sir Henry's neighbour - old Frankland . He told me her story. She had married an artist named Lyons who soon deserted her . Her father refused to help her , because she had married without his permission . Besides he had very little money himself . The neighbours were sorry for her , and several of them helped her to learn typewriting and get some work . Stapleton and Sir Charles were among those who gave her money . She was now living at Coombe Tracey .
I didn't tell Mortimer why I was so much interested in the woman , but tomorrow I shall go to Coombe Tracey and try to find her . She may help to make things much clearer .
There is one more incident to put down on this unpleasant day . It is my conversation with Barrymore .
“ Has your wife's brother gone at last? ”
“ I don't know , sir , for I did not see him when I brought his food three days ago . ”
“ But did you find the food at that place the next time ?”
“ No , I didn't , but perhaps the other man took it . ”
“ You know that there is another man then ? Have you seen him ? ”
“ No , sir. but Selden told me about him , a week ago . ”
So Selden had seen that other man too ! Who is he and what is he doing there all alone ? Now I must devote all my energy to try and solve this new problem .
Chapter XIV
EXTRACTS FROM THE DIARY OF DR . WASTON
( 华生医师日记摘录 )
( Continued )
October 18th. At breakfast I told Sir Henry about my meeting with Dr. Mortimer and our conversation about Laura Lyons . It was decided that I must go to Coombe Tracey alone , and I started in the afternoon . Mrs. Lyons was at home and received me . My first impression of her was that she was very beautiful , but when I looked at her more attentively I noticed something impolite and hard in her face . She asked me about the reason of my visit .
“ I have come to speak to you about Sir Charles Baskerville .”
“ What can I tell you about him ? All I can say is that he was very kind to me and helped me much . ”
“ Were you ever in touch with each other by writing letters ?”
The lady looked angry . “ What is the purpose of your question ? ” she asked sharply .
“ I want to avoid getting you out of trouble , Mrs. Lyons. It's better to speak here than at the police station . ”
She was silent and her face was very pale . “ Well , I will answer your questions . Ask me what you like . ”
“ I repeat my question . Did you write to Sir Charles often ? ”
“ I wrote to him only once or twice to thank him for his kindness .”
“ Did you ever meet him ? ”
“ Yes , several times , when he came to Coombe Teacey . ”
“ Did you ever write to Sir Charles , asking him to meet you at the moor gate ? ”
Mrs. Lyons was now red with anger . Certainly not .”
“ Did you not write to him on the day of his death ?”
Her face grew white again . She could not speak .
“ Tell me why you wrote to Sir Charles and asked him to be at the gate that night . Why did you beg him to burn the letter ? ”
Mrs. Lyons was now so pale that I thought she would faint .
“ This is a private matter . I cannot tell you .” she answered almost in a whisper .
“ Mrs. Lyons . If I have to call in the aid of the police , you will find how serious your position is .”
“ I will tell you then ,” she answered through tears . “ My life has been very hard . I had made an unhappy marriage and my father refused to have anything to do with me . I could not get a divorce (离婚) from my husband without a large sum of money . I thought that if Sir Charles heard the story from my own lips he would not refuse to help me . I wrote to him , but I was afraid that somebody might see the letter , so I begged Sir Charles to burn it .”
“ But why did you ask him to meet you at the gate at such a late hour? ”
“ Because I had only just learned that he would go to London the next morning .”
“ Well , what happened when you went there ? ”
“ I never went there .”
“ Mrs. Lyons ! ”
“ I swear that I am speaking the truth . At the last moment I received help from another person .”
“ But why did you not warn Sir Charles ? ”
“ It was too late . I wanted to write and explain everything the following morning but I saw the report of his death in the papers .”
The woman's story sounded truthful . I could get nothing more out of her, though I felt that she had not told me everything . Why had she lied at first ? Why had she been silent at the time of Sir Charles's death ? I asked myself that over and over .
On my way home I decided to explore the moor once more , and try to find some traces of the mysterious stranger whom I had seen on the moor . There were many deserted huts scattered on the moor , and I was sure that the man must be hiding in one of them . I climbed a hill to have a better look at the surroundings when suddenly I saw a small figure on the top of one of the hills at the end of the path . The day was clear and , though the distance was great , I could see that it was the figure of a boy carrying a small package on his shoulder . In another moment he had disappeared behind the hill . I walked quickly in the same direction , but I failed . He was nowhere to be seen . There was silence around and I felt lonely and frightened . The huts were all quite ruined , as nobody had lived in them for many years . At last I came upon a hut which had something like a roof over it . My heart beat fast . I thought that this must be the hut where the stranger was hiding . I put my hand upon my revolver and looked in . The place was empty , but there were many signs that somebody lived there . Some blankets lay on the stone floor and a basin of water stood in the corner . In the middle of the hut lay a small package . It looked like the one I had seen on the boy's shoulder . It contained a loaf of bread and some meat . Under it was a sheet of paper . “Dr. Waston has gone to Coombe Tracey ” was written on it . It was I then , not Sir Henry , who was followed . What did all these mean ? Who could live in this lonely hut on the moor ?
Outside the sun was setting . All seemed peaceful in the golden evening light , yet my heart was full of fear as I sat in the dark corner of the hut , waiting for the coming of the stranger . And then at last I heard him . Far away , then nearer and nearer came his steps . There was a long pause which showed that he had stopped . I did not move , but held my revolver ready . The footsteps was closer again and a shadow fell across the opening of the hut .
“ It's a lovely evening , my dear Waston ,” said a well-known voice . “ Come outside , please . ”

( 华生医师日记摘录 )
(Continued )
For a moment or two I was so much surprised that I could neither move nor speak . Then my senses and voice came back to me . “ Holmes , Holmes , is that really you ? ” I cried .
“ Come out of the hut , and please be careful with your pistol .” said he .
He was thin and looked tired , but his shirt was as white as if he were in Baker Street , and his eyes were laughing as he asked : “ Why don't you say you are surprised ? ”
“ My dear Holmes , I am so surprised and I am so glad to see you ,” I answered shaking his hands .
“ If you are surprised to see me , I am just as surprised to find you in this old hut . I understood that you were here only when I was about 20 steps from the hut .
“ Oh , you saw my footprints , of course ? ”
“ No , not your footprints , but the cigarette that you threw down when you entered the hut . We have lived together so long that I know your cigarettes well . But how did you find my hiding-place ? ”
“ I saw a boy carrying a package on his shoulder . He was climbing this hill and I followed him . ”
“ That was Cartwright , the boy who often helps me . He is very clever and active and has brought me food and clean suits . ”
“ But my dear Holmes , why did you not trust me ? Why did you keep me in the dark ? I thought you were in London .”
“ My dear Waston , you must not be angry with me . Your reports have been of great help to me . I beg you to forgive me . I was obliged to cheat you , for I knew that this matter was very dangerous and difficult , and I could not leave you here alone . At the same time I thought it better to keep my presence a secret from everybody , even from you . I have discovered many things living on the moor . Do not ask me for details yet , but I can tell you that in a day or two . My nets will close upon the murderer , for I know now that there is a cold-blooded murder in the case.”
“ But why does the boy follow me ? What does this note mean ? ”
“ I wanted to know what you had decided to do . If you had not gone to Coombe Tracey today , I should have gone there tomorrow myself . Mrs. Lyons is the only person who may help us in this matter . ”
The sun had set and the air had grown cold . We went into the hut and sat down on the blankets that lay in the corner . I told Holmes about my conversation with Laura Lyons . He took great interest in it and when I had finished he said : “Do you know that this lady is Stapleton's sweet heart ?
“ I did not know it , ” I answered .
“ There can be no doubt about it . They meet , keep in touch , and have a complete understanding between them . It is he who told her that Sir Charles was going to London , and it is he that offered her money at the last moment . ”
“ But why , Holmes ? ”
“ Because he wanted Sir Charles to be alone at the gate .”
As we sat in the darkness of that lonely hut on the moor , Holmes told me what he had found out during that time . When he learned from my report that Stapleton had been a schoolmaster in the North of England , he made inquiries . It appears that Stapleton had robbed the school where he taught and fled from that part of the country , with his name changed .”
“ The lady whom you call Miss Stapleton is in fact his wife ,” said Holmes.
“ His wife ! Is it possible ? Why then did he allow Sir Henry to fall in love with her ? ”
“That only helped him in his plans . But he did not allow Sir Henry to make love to her . You told me that yourself in your report . ”
“ And how do you explain all this ? ”
“ He hoped that it would help him in his ill plans , ” Holmes answered . “ Then he must be our enemy - the man who followed us in London .”
“ I think so .”
“ But if he has a wife , what could he promise to Mrs. Lyons ? ”
“ Your talk with the lady shows that she hoped to become Stapleton's wife after a divorce from her husband . ”
As I listened to Holmes , I began to see something terrible in that colourless man with his straw hat and his butterfly-net . A cunning man with a smiling face and a murderous heart . “One last question , Holmes . What is the meaning of all this ? ”
“ It is murder , Waston , cold-blooded murder . Do not ask me about the details yet . In a day or two I shall know everything , but there is one danger - it's that the murder will act before we are ready . So until then look after Sir Henry . Even now I am sorry you are not with him .”
A loud scream full of horror and fear broke the silence of the moor . We both jumped to our feet and dashed out of the hut .
“ Oh , my God ! What is it ? What does it mean ? ” I exclaimed .
“ Hush ! Hush (切莫出声）！” whispered Holmes .
The cry was repeated nearer and louder and more terrible than before .
“ Where is it ? ” Holmes whispered again and I felt that even he was frightened .
“ There , I think , ” I pointed into the darkness .
Again the cry turned up , but now a new sound was heard , like the growling （狂叫）of a dog .
“ The hound ! Come , Waston , come , or we may be too late . ”
He ran over the moor and I followed him . The loud cries were repeated somewhere quite near . Then we heard a heavy fall and all was silent .
“ He has beaten us , Waston . We are too late . ”
Blindly we ran through the darkness . The moor was now quite dark and we could see nothing .
We stopped and Holmes struck a match . By its light we noticed something not far from the place where we stood . When we came nearer , Holmes struck another match and with horror we saw that it was Sir Henry Baskerville . We both recognized the brown suit he had worn in London . We stood near the body , and our hearts were full of sorrow and despair .
“ Oh , why did I not act before ,” cried Holmes , “ and you , Waston , why did you leave him ? ”
“ Oh , Holmes , I shall never forgive myself .”
“ I am more guilty (负有责任）than you , Waston . But how could I know that he would go out alone in spite of my instructions ? ”
“ My God . We heard his screams and yet we could not save him . Where is the hound now ? And where is Stapleton , the murderer ? ”
“ He will answer for this . But now we must send for help . We cannot carry him all the way to the Hall .”
He bent over the body and suddenly let out a cry of joy .
“ A beard ! A beard ! ” he exclaimed , and began dancing and laughing .
“ My God , Holmes . Are you mad ? ”
“ The man has a beard ! It's not Sir Henry ! ”
We turned thr body over and looked into the dead face of - Selden - the escaped prisoner . Then in a moment all was clear to me . I remembered that some days before Sir Henry had given Barrymore his old clothes , and Barrymore had clearly passed them on to Selden to help him in his escape . But there really was a hound on the moor , for we had both heard its growls . Obviously the animal had chased the prisoner . In his terror he had fallen over a large stone and broken his head . There was blood on it . But why had he been so terrified ? Where had the hound disappeared ? Why had it chased Selden ? This was still a mystery .
“ Why can't we arrest Stapleton at once , Holmes ? ”
“ Because we can't prove much yet . we cannot prove the connection between him and the hound . If we are not careful , he may escape . But what's this , Waston ? It's Stapleton himself coming across the moor . Not a word to show your suspicions (怀疑） or all is lost ! ”
“ Hello , Dr. Waston ! What are you doing on the moor at this late hour ? ” said Stapleton , coming forward with a cigar between his fingers . “ Oh . I am sorry , I see that you are not alone . ”
“This is Mr. Holmes , ” I answered .
“ Dear me ! What's this ? Is somebody hurt ? I hope it is not our friend Sir Henry !” He was bending over the body . The cigar had fallen from his fingers and his face had grown quite white .
“ It's Selden , the escaped prisoner ,” I answered , looking Stapleton in the face . For a moment he was silent , then , hiding his disappointment and surprise he said :
“ I heard a cry . I was anxious about Sir Henry and ran out to see what had happened . ”
“Because I was expecting him at Merripit House and he did not come . Then I heard cries on the moor . By the way , did you hear anything else besides a cry ?”
“ What do you mean ? ”
“ Oh , you know the story about the terrible hound . They say it's sometimes heard on the moor at a late hour . I thought perhaps - ”
“ We heard nothing of the kind ,” I said .
“What's your opinion of this poor fellow's death ? ” he asked .
“ I suppose he fell over a stone and broke his head ,” I answered .
“ I think you are quite right
