1. This is so interesting a book __________ we want to read it.

2. This is so interesting a book __________ we want to read.

A. which B. as C. that D. what

参考答案：1. C 2. B

解析：句1是so...that结构，表示“如此……以至于……”，that引导结果状语从句；句2是定语从句，先行词被so修饰，所以用as引导。

解此类题目时，看横线后面的成分是否完整。若成分完整，则是“so/such...that”结构；若成分不完整，则用as引导定语从句。

3. __________ ways to praise your children often，and you’ll find they will open their hearts to you.

4. __________ ways to praise your children often，you’ll find they will open their hearts to you.

A. Find B. Found C. Finding D. To find

参考答案：3. A 4. C

解析：句3是“祈使句+and+结果分句”结构，所以用动词原形；句4是分词短语作状语，表示条件，you与find之间是主谓关系，所以用现在分词。

解此类题目时，看句中是否有连词and / or。若有连词，则构成“祈使句+and / or+结果分句”结构；若没有连词，则为分词作状语。

5. The book was written in 1946，__________ the education system has witnessed great changes.

6. The book was written in 1946；__________ the education system has witnessed great changes.

A. since then B. during which

C. when D. since when

参考答案：5. D 6. A

解析：句5是非限制性定语从句，定语从句用的是一般现在时，缺少时间状语，所以选择D项；句6是并列句，后半句缺少时间状语since then。

解此类题目时，主要看横线前的标点符号。若标点符号是逗号，则通常属于主从句类型；若标点符号是分号，则通常属于并列句类型。

7. It was at ten o’clock __________ my father came back with two little sisters.

8. It was ten o’clock __________ my father came back with two little sisters.

A. when B. which C. that D. since

参考答案：7. C 8. A

解析：句7是强调句型，对时间状语at ten o’clock进行强调；句8是“it+be+时间名词+when从句”句型。

解此类题目时，主要看ten o’clock前有没有介词at。若有介词at，则通常用that构成强调句型；若没有介词at，则通常用when引导，构成“it+be+时间名词+when从句”句型。

9. It is the first time that we __________ a film in the cinema together as a family.

10. It was the first time that we __________ a film in the cinema together as a family.

A. see B. have seen C. saw D. had seen

参考答案：9. B 10. D

解析：句9表达的是过去动作对现在产生的影响，所以用现在完成时；句10表达的是“过去的过去”的动作，所以用过去完成时。

解此类题目时，主要看前面主句的be动词。若be动词是is/will be，则从句动词用现在完成时；若be动词是was，则从句动词用过去完成时。
