Unit 4
本单元的语法重点是名词性从句，而名词性从句的考查在高考试卷单项选择一题中一般情况下占20%，即在20个小题中有一个小题。如： 答案：1.A；2.A
1.─I drove to Zhuhai for the air show last week.
─Is that _____ you had a few days off ?
A. why B. when C. what D. where (NMET99)
2.─It was _____ he said _____ disappointed me.
A. what; that B. that; that
C. what; what D. that; what (上海99)
分析：
句1：从题干和所给的4个选择中不难看出本题考查的是表语从句。“I drove to Zhuhai for the air show.”提出一个事实，而第二句表明“I”不在的原因。故答案为A.why。
句2：该句考查的是强调句和主语从句。该句强调的是句中的主语，而该句的主语又是一个从句。从这个结构中可以看出第二个空和“It was”构成强调句，故第二个空应该是that；第一个空和“he said”构成主语从句；在这个从句中“said”一词后缺少宾语，故答案为A.what;that。

名词性从句 10 注意(3A Unit 4)
1. 主语是 reason 的表语从句要用 that 引导，而不用 because。
The reason (why) I came to school late today was that I didn‘t get up on time . 今天我上学晚的理由是我没准时起床。
2. that 作连接词，除少数介词(except , but , in)外，一般不能作介词宾语。that 引导的从句如果作其它介词的宾语，就需用 it 先行一步作形式宾语，把 that 从句后置。
I didn’t look anywhere except ／ but (that I looked) in your room . 除了你的寝室以外，我那儿也没找。
You may depend on it that they will support you . 你可以依靠他们来帮你。
3. whether 引导所有名词性从句，能用于作介词宾语从句；和 or not 连用；用在 discuss , argue 等动词后和 sure , certain 等形容词后，引导宾语从句。
Whether it is true remains a question . 此事是否属实有待证明。
Please tell me whether he is there or not . 请告诉我他是否在那里。
We discussed whether we should close the shop . 我们讨论是否关闭这家商店。
4. 动词 doubt 用在疑问句或否定句时，其后宾语从句常用 that 作连接词；用在肯定句时，连接词用 whether 或 if 皆可，而不用 that。
Do you doubt that he will win ? 你难道怀疑他将取胜 ?
I don‘t doubt that your proposition is wrong . 我相信你的建议是错的。
He doubt whether I know it . 他怀疑我知道了此事。
5. 连接代词不仅有连接作用，而且还在从句中充当主语，表语、定语等句子成分。常见连接代词有 who , whom , whose which , what , whatever , whoever。
What surprised me most was that he won the first prize . 最使我吃惊的是他赢得了一等奖。(what 作从句主语)
6. 连接副词除了连接从句外，还在从句中作状语。常见连接副词有 when , where , why , how。
How he became a great success is known to us all . 他怎样成了一个成功人物大家都知道。(how 在主语从句中作状语)
7. 名词性从句的语序。无论名词性从句是疑问句，还是陈述句，它的语序应为陈述语序。
Do you know when he will come back ? 知道他何时回来吗 ?
8. 正确掌握名词性从句谓语动词的时态。这是学习和掌握名词性从句的难题之一，在名词性从句中重点是宾语从句谓语动词的时态。
● 若主句谓语动词为一般现在时和一般将来时，宾语从句的动词可根据句意用它所需要的任何状态。
Will you tell me how you learned English well ? 告诉我你怎么学好英语的，好吗 ?
I think he’ll be back in an hour . 我想一小时后他会来的。
● 若主句谓语动词是过去时态时，从句中的动词须用过去的相应时态。
I thought they were having lessons . 我想他们正在上课。
She said she had done her homework . 她说她已做完了作业。
Mary said she would help me with my English . 玛丽说她将帮我学英语。
● 宾语从句表达客观真理，不论主句是什么时态，从句都用一般现在时。
The teacher told us light travels faster than sound . 老师告诉我们光的速度比声音快。
9. 否定转移问题。在主句为第一人称主语后跟 think , believe , suppose , expect , guess , imagine 等动词时，宾语从句的否定形式应转移到主句中。
We don‘t expect he will come tonight , will he ?
