高中英语语法专项练习之主语从句
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 ______nightbegan 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。

本题考查主语从句的引导词。
