二、重难点句子

1. Scientists, on the other hand, Hawking writes, know that their job is never finished and that even the best theory can turn out to be wrong.

  霍金写道,从另一个方面说,科学家知道他们的工作永远是无止境的,即使是最好的理论也可能被证明是错误的。

(1)on the other hand 与Hawking writes 均为本句的插语,原句应为:

   Hawking writes scientists, on the other hand, know that…, scientists know that…是writes 的整个宾语主句,that their job… 则又是宾语从句中的谓语动词 knows 所引导的另一个宾语从句。

(2)…and that even the best theory can turn out to be wrong 是writes 引导的宾语从句中谓语动词know引导的第二个并列宾语从句。在英语中,宾语从句的引导词that可以被省略,但如果一个动词引导两个以上并列的宾语从句时,第二个及以后的宾语从句中的that不可省略。例如:

   He said that he would come back soon and that he would continue to learn drawing.

   他说他马上就会回来的,而且会继续学习绘画的。

(3)turn out“结果(是);证明(是);原来(是)”(to happen to be in the end)往往指结果与所预想的或表面上的不一致。例如:

   His answer turned out to be wrong.

   他的答案被证明是错误的。(turn out to be…)

   The party turned out a success.

   聚会很成功。(turn out sth)

(天气)终于又是阳光普照了。

2. By asking why, how and what if, curious mind find new ideas and solutions.

通过不停地问自已为什么,如何运作和盘根究底的假设,这个求知的人终于找到新的主意及方法了。

what if倘使…将会怎样;即使…又有什么要紧。

例如:

What if we move the picture over here? Do you think it'll look better?

把画移到这儿会怎样?你看会不会好看一点?

What if you should fail?

假如你失败了,该怎么办呢?

What if he fails?

如果他失败又有什么关系?

高考解析

1、I have worked with children before, so I know what _______ in my new job.(2000 NMET)

A.expected              B.to expect

C.to be expected            D.expects

命题目的:考查“What to expect”中的不定式在句中做宾语.

解题方法:

此题答案为B.“疑问词+不定式”常相当于名词的作用,在句中充当主语、宾语、表语等。所以此题可排除A、D。而这个不定式的动词 except 与 what 构成动宾关系,应用不定式的主动语态表示被动含义,所以排除C。

2、It is ________ that he has left out _______ “n”in the word “government”.

A.obvious; an             B.obviously; a

C.clear; the              D.clearly; a

命题目的:句型及冠词的用法.

解题方法:

   此题答案为A。第一空用在句型It is obvious /clear that…表示“很显然”,此句型相当于Obviously /Clearly…;第二空在元音音素前,用不定冠词“an”。

3、-Will you go to ask him for help?

  -But ______ he is busy?

A.when                B.once

C.what if               D.what

命题目的:考查what if的用法.

解题方法:

  此题答案为C。“what if”表示“假如……的话,该怎么办?”又如:What if the earth broke up?如果地球爆炸了,会怎么样呢?

A.I will B.will I C.do I D.I shall

答案及提示

1.C. undertake to be“担当(职位),作为(身份)”,相当于act as或work as.

2.D. 根据上下文可知说话人想知道“这餐桌是不是空的”。engaged指“被合用”之意。

3.C. 不定式的逻辑主语应为人,即排除A、B、D为被动语态,不合句意。

4.C. 不定式指代形式主语it,又因为前面是to lose one’s life,为不定式形式,所以要求形式上的统一。

5.A. 为定语修饰先行词boy,根据上下文应强调当时的情景。B、D语法上均错误。C时态不是最佳。

6.D. discuss“讨论”,句型为:discuss sth with sb

argue “争论”,句型为:argue with sb about /over sth.

Talk with sb“与……交谈”。根据本题之意,应为“辩论”。

可说:debate sb.(与某人辩论),也可说debate with sb about /upon sth

7.C. If only“如果……就好了”后面可接真实及虚拟语气。本句是一与过去相反的虚拟语气。意思是“如果我在参加这次讲座之前,读了阅读目录上的文章就好了”。

8.A. with+复合宾语,time与后面的动词是主谓关系,即用现在分词。

9.B. 根据上下文,这应该是上文的原因的必然结果。

10.C. 不定式作定语修饰pen.因为:He must write with a pen.须用to write with .seem后须用不定式.

11.A. seek sb“寻找某人”相当于seek for /search for.

12.A. There is no doubt that…是固定句型,“毫无疑问”,dream of“梦想,渴望”。

13.B. “only+状语从句”位于句首时,主句须用部分倒装语序。
