高中英语主语从句练习及答案

英语练习: 主语从句

Ⅰ. 用适当的连接词填空

1.They lost their way in the forest and ______made matters worse was ______night

began to fall.

what, that and连接两个分句，and后面的分句中含有一个主语从句和一个表语从句；主语从句中缺主语，what made matters worse “使事情更糟糕的是…”，后面的night began to fall意义完整，作表语，不需要有意义的引导词，所以填that。

2. There is no doubt, in my opinion, that _________matters is not the quantity, but the quality of the products.There is no doubt that…. “毫无疑问…”，in my opinion 是插入语，that引导的是一个同位语从句。that同位语从句中又含有一个主语从句:_____matters, matter 是谓语动词，指“有关系，要紧，重要”，其前无主语，所以填what。

3. It doesn’t interest me _______you succeed or not.

It是形式主语，替代后面的主语从句。由or not可知该空填whether。

4. _______the astronaut ate his food in space is _______we want to know.

How, what（如果你懂得来龙去脉，可以不看下面的文字）一定要懂得句子作一个成分如主语或宾语时，一定有一个引导词+陈述句，而这个引导词的选择取决于意义和句子成分。还有一点关键的，不少同学不会断句，根本不知道哪里是从句。如果一眼看不出来，先找动词，动词要不前面有名词或代词，要不后面有名词或代词，如果是不及物动词，后面就没有宾语。以这句为例：动词有ate,is, want , know, 看ate,前面有astronaut, 是主语，ate后面有his food，是宾语，句意为“宇航员在太空中吃食物”。is “是”，we want to know “我们想知道”，大脑加工一下信息：“宇航员在太空中吃食物”+ “是”+“我们想知道”, 这句话显然意思不通，必须加符合意义的词，这个词还要肩负引导一个从句的作用。“宇航员在太空中吃食物”这句话主谓宾齐全，所以引导词用连接副词，而不是连接代词。好吧，什么是连接副词？又有哪些连接副词？脑补一下，when，where，why，how，那个意义符合，how最佳，似乎when也可以，这是单句填空，如果在文中，看上下文需要什么意思。Where不可以，后面有in space，你觉得why可以吗？“宇航员为什么在太空吃东西”，这问题很搞笑，不在太空，在哪里？

再看后面的部分，是表语，由句子充当，叫表语从句，we want to know,我们想知道, 想知道什么（事或东西），know缺一个宾语，哪个词表示“…的东西、事情”，只有what，千万不能用that，that只起引导作用，把一个完整意义的句子归到它的名下，一同去充当某个句子成分。What不但起引导作用，还要在它统率的句子里作一个成分，而在上面的句子里，what作know的宾语。

5. ______ you can make your dream come true depends on hard work more than luck. Whether 先断句，“你可以让你的梦想变成现实”+取决于+努力+而不是运气，“你可以让你的梦想变成现实”这一部分是句子的主语，相当于一个名词，但缺领头的引导词，这句主谓宾齐全，考虑填连接词that,if ,whether, 或连接副词

when，where，why，how。把整个句子结合起来，whether最佳，表示“是否”。If不能放在句首。

6._________we are permitted to use the library is not known. (Whether)

7. ________the author referred to in his article was unknown to the general reader. (What)

8.________colours influence our moods has been proved.

That 句子表达的事情有三大类：1）确定的事，一件事实，用that引导。2）不确定的的事，用whether或if引导。3）具体的问题的事用各类疑问词引导，如想知道原因用why引导，想知道谁的用whose引导，哪一个用which引导。上面的句子属于哪种情况？prove “证实”，显然是确定的事。前面的主语从句用that引导，that没有意义，只起引导作用，没有它，句子就乱套了，意思杂糅。

9._______will be our English teacher in the new term hasn’t been decided yet. （Who）

10._________you can succeed or not depends on how hard you work at it.(Whether)

11.—It remains to be seen _______the plan can be put into practice.

—It depends on your determination. (whether/if it是形式主语。这里可以用if，因为不是在句首)

12._______ more and more students show little interest in her classes makes her puzzled. （Why）

13. _______ made the school proud was ______ more than 80% of the students had been admitted to key universities. （What, that）

14. ______ is our belief that improvements in health care will lead to a stronger, more prosperous economy.

It it是形式主语，that引导的从句是真正的主语。这句话还有两种考法：

1）What is our belief is that improvements in health care will lead to a stronger, more prosperous economy.（主语从句+表语从句）

2）As is believed, improvements in health care will lead to a stronger, more prosperous economy. (as引导定语从句)

比较一下不同点。

15.________ you don't like him is none of my business. （That）

这句容易填whether，如果用whether，句子为Whether you like him or not is none of my business.

16.________makes this shop different is that it offers more personal services. (What)

17. It was _______he said _______disappointed me.(what, that) that为强调句型的引导词
