高一英语第二十单元 Mainly Revision


D. because

析:⑴ B ⑵ A 。 句 ⑴ 是 that 引导的定语从句,that 在从句中作 give 的宾语,因先行词 reason 之前有 best 修饰,故只能用 that 。句 ⑵ 是 why 引导的定语从句,相当于 for which 。

【指点迷津】

是定语从句还是状语从句 ?

你在做这样一道选择题时,该选哪个答案呢?

While reading the book , we\'d better make a mark we have any question .

A. at which B. at place where C. in which D. where

你或许要选择选项 A 或 C ,因为你认为此句含有一个介词 + which 引导的定语从句,然而句中的“ mark ”在逻辑意义上并非先行词,因为我们决不是在 mark 上有任何问题,所以 A 和 C 都不是正确选项。那么选择 B 正确吗?回答是否定的,虽然选项 B 中的“place ”可以充当 where 引导的定语从句的先行词,但单数可数名词被限制性定语从句表特指的概念,“ place ”前应有 冠词“ the ”。正确选项只能是D 了,即是由 where 引导的地点状语从句,此句中的 where 等于 at the place where 。再看下列句子。

I\'d like to take the pictures where stands the ancient tower . 我想在古塔那个地方照几张像。

Please put the chair where it was when the meeting is over . 请在会后把椅子放回原处。

Young people should go where they are badly needed . 青年人应该到最需要他们的地方去 。

以上三个句子均含有 where 引导的地点状语从句,句中的 where 可分别是由 in the place where , at the place where , to the place where 等替换。综上所述,引导地点状语从句的 where 通常可由适当的介词 + the place + 关系副词 where 替换,只要我们抓住这个关键就不难准确判断和使用 where 引导的定语从句和地点状语从句。最后再请试做下列选择题。

⒈ Many old people like to live there are many trees and flowers .

A. in which B. the place where C. in the place where D. which

⒉ This kind of bamboo grows best it is wet and warm .

A. which B. in which C. where D. the place in which

⒊ Africa is actually connected with Asia at the spot the Suez Canal was dug .

A. which B. in the place where C. the place where D. where

⒋ This is the laboratory we made the experiment the other day .

A. in the place where B. that C. which D. where

⒌ The nurse asked the children to sit they were .

A. at place where B. where C. the place where D. which

答案:1—5 CCDDB
