定语从句与其近似句型简析

⒈ ⑴ It is such a modern machine few of the workers know how to operate it .

⑵ It is such a modern machine few of the workers know how to operate .

A. which B. that C. as D. the one

析：⑴ B ⑵ C 句 ⑴ 是 such … that 引导的结果状语从句。句 ⑵ 是定语从句，先行词前有 such 修饰时用 as 引导，as 在定语从句中作 operate 的宾语。

⒉ ⑴ Is this museum they visited last week ?

⑵ Is this the museum they visited last week ?

⑶ Is this farm you used to work ?

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

析：⑴ D ⑵ B ⑶ A 句⑴、⑵是定语从句：句 ⑴ the one 是先行词，后面省略了 that 。句 ⑵ 关系代词 that 在定语从句中作 visited 的宾语，此句还可用 which 或省略关系代词。句 ⑶ 是 where 引导的表语从句。

⒊ ⑴ is well known to us all , the earth goes around the sun .

⑵ is well known to us all that the earth goes around the sun .

A. That B. As C. It D. Which

析：⑴ B ⑵ C 。句 ⑴ 是由 as 的非限制性定语从句，代替后面整个句子。句 ⑵ 是it 引导的主语从句。 it 是形式主语，真正的主语是 that 引导的从句。

⒋ ⑴ I have two sisters , are doctors .

⑵ I have two sisters , and are doctors .

A. both of them B. both of whom

C. neither of them D. each of whom

析： ⑴ B ⑵ A 。句 ⑴ 是定语从句， 因从句中动词是 are ，所以只能选 B ，而不能选 D 。句 ⑵ 因有并列连词 and ，所以是并列句，再根据主谓一致原则，只能选 A 。

⒌ ⑴ I\ll never forget the days I spent with him .

⑵ I\ll never forget the day I was born .

A. when B. that C. on which D. both A and C

析：⑴ B ⑵ D 。 句 ⑴、⑵都是定语从句，句 ⑴ 中 that 在从句中作 spent 的宾语，还可用 which ，也可省略。句 ⑵ when 在定语从句作状语，也等于 on which ，故选 D 。

⒍ ⑴ Was it October 1 , 1949 the People\s Republic of China was founded ?

⑵ Was it on October 1, 1949 the People\s Republic of China was founded ?

A. in which B. on that C. that D. when

析：⑴ D ⑵ C 句 ⑴ 是 when 引导的定语从句，句 ⑵ 是强调句，特别注意句 ⑵ 中 October 之前的 on 。

⒎ ⑴ He is the only one of the students who the accident .

⑵ He is one of the students who the accident .

A. knows B. know C. had known D. known

析：⑴ A ⑵ B 句⑴、⑵都是定语从句，在“ the ( only ) one of + 复数名词 + 定语从句”结构中，先行词是 one ，而不是复数名词，故从句中谓语动词用单数。但是在“ one of + 复数名词 + 定语从句”句型中，先行词是复数名词，故从句中谓语动词用复数。

⒏ ⑴ Do you know the fact the sun is brighter than the moon ?

⑵ Do you understand the easiest fact he explained to you just now ?

A. that B. which C. the one D. as

析：⑴ A ⑵ A 句⑴是 that 引导的同位语从句， that 在从句中不作任何成分，不能省略。句 ⑵ 是 that 引导的定语从句， that 在从句中作 explain 的宾语，因先行词 fact 之前有最高级限制 easiest ，故只能用 that ，不可用 which 。

⒐ ⑴ This is the best reason he could give at the meeting .

⑵ This is the reason he didn\t go to school this morning .

A. why B. that C. which 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
