名词性从句
考点复****1
考点一 主语从句
主语从句是在复合句中担任主语的句子。其特点有：
（1）引导词：
从属连词 that, whether；
连接代词 who, what, which；
whoever, whatever, whichever;
连接副词 when, where, how和why。
（2）语序：陈述句语序
（3）在主语从句中只能用whether，不能用if
That he will win the match is certain.
It is certain that he will win the match.
1. 一般来说主语从句都是放在句首，但有时为了使句子保持平衡，避免"头重脚轻"，常用it作形式主语，从而把主语从句放后面。常以it作形式主语的句型有：
①It is＋形容词＋that...
It is certain that she will do well in her exam.
毫无疑问她考试成绩会很好。
②It is＋名词词组(no wonder，an honour，a good thing，a pity，no surprise，common knowledge，a surprise，
a fact，etc. )＋that...
It’s a pity that we can’t go.
很遗憾我们不能去。
③It is＋过去分词(said，reported，thought，expected，decided，announced，arranged，etc. )＋that...
It has been suggested that much should be done to prevent the river from being polluted.
有人建议应做更多的工作阻止河流遭受污染。
④It appears/seems that...|It happens that...|It occurred to me that...|It turned out that...
It turned out that nobody remembered the address.
结果发现没人记得这地址。
⑤It doesn’t matter that...|It makes no difference that...
It doesn’t matter whether she will come or not.
她是否来这无关紧要。
2. 当that引导的主语从句出现在疑问句中时，要以it作形式主语，而把主语从句后置。
Does it matter much that they will not come tomorrow？
他们明天不来很要紧吗？
3. 当主语从句出现在感叹句中时，要以it作形式主语，而把主语从句后置。
How strange it is that the children are so quiet！
孩子们这么安静真奇怪！
【典例分析】
1. (2020﹒天津)The student completed this experiment to make come true ______ Professor Joseph had said.
A. that B. what C. when D. where
【答案】B
【解析】考查名词性从句。句意:为了使约瑟夫教授所说的成为现实，这个学生完成了这个实验。_________ Professor Joseph had said作make的宾语从句，该从句中，空处在从句中作said的宾语，表示”……所说的话”，因此应用what引导该从句。故选B。
2. (2019﹒新课标I卷)While they are rare north of 88°,there is evidence 61 they range all the way across the Arctic, and as far south as James Bay in Canada.
【答案】that
【解析】考查同位语从句。根据句子结构分析可知，主句为there be句型，且结构完整，空格后为同位语从句，解释说明中心词evidence的内容，故填that。
3. (2019﹒北京)What students do at college see
