学习英文的过程中，最难的点久在语法。语法掌握不好，英语就学不好。很多学生看到语法问题都不知道。的确，学习语法很困难，但是随着时间的推移，铁会磨成针，今天，我要谈谈语法中的同位语从句。
同位语从句
阅读过程中会看到这种类型的句子：一个名词（或其它形式）对另一个名词或代词进行修饰，限定或说明。其实这个名词（或其它形式）就是同位语。同位语与被它限定的词的格式要一致，并常常紧挨在一起，同位语从句即重复说明同一个称谓或事件的从句。
名词作同位语
王老师，我孩子的老师，星期二要来看我们。
（这里是“我孩子的老师”做的“王‘先生”）
短语作同位语
作为家里的一个女孩，我总是照顾家里的其他孩子。
直接引语作同位语
但现在他们想到的问题是”她英年早逝是因为她是克隆人吗?”
句子作同位语
The girls were surprised at the fact that ocean ships can sail up the Great lakes.巨大的海轮可以开到五大湖,让表姐妹俩感到吃惊.
1.同位语从句进行讲解-定义：用作一个同位语的从句可以叫做同位语从句。
如果你不想上学，你就必须去上学，你必须去上学，你必须去上学。 例如：
They’re all worried you’re sick.
他们都担心你生病了。
Where did you get the idea that I could not come?
你从哪里听说我不能来？
News came earlier in the day that Germany had declared war on Russia.
德国对俄国宣战的消息于清晨传来。
注：同位语从句可以偶尔由从属关系连词whether引导。如：
I have no idea whether he’ll come or not. 我不知道他是否来。
连接代词who, which, what和连接副词where, when, why, how亦可引导同位语从句。
The question of who should do the work needs to be considered.
谁该干这项工作，这个问题需要考虑。
We have not yet solved the problem of where we will spend our summer vacation.
我们还没有决定去哪里度暑假。
The question is, how did he do it.
那是他如何做的问题。
解释：
1.that引导的同位语从句与定语使用从句之区别
that引导的同位语从句
由它指导的定语从句
句法功能上：
它只是一个连接子句，没有任何意义。不充当句子中的句子成分。不要吝啬。
它不仅代替先行词作为从句中的连接词，还代替先行词作为句子成分。如果你是从句中动词的宾语，你可以省略它。
意义上：
从句是被修饰一个名词的内容。
从句起限定作用，是定语
A: the news that Miss Li will be our new English teacher is true.
李先生将成为我们的新英语老师的消息是真的。
The news （that） he told me yesterday is true. （定语使用从句，that在从句中作told的宾语，可省。）
他昨天老师告诉我的消息是真的。
2.在一些类似的从句中，跟着名词“暗示、命令、请求”，谓词动词表示为+动词的原始形式。应该可以保存。符合：
This is the only request we have for speedy resolution.
这是我们的要求: 尽快解决这个问题。

15. He often thought he could do more for the Four Modernizations. What? What? What
答案及分析:1。c引导主语从句、同位语从句和表语从句时不省略，但引导宾语从句时可以省略。2.b当……或无论什么……或3。他正在做什么。4.由that引导的主语从句通常由正式主语代替。5.由that引导的主语从句通常由正式主语代替。新闻是不可数名词，选C 6。B \\ \"计划如何实施还有待商榷\\ \"，语序应该是表语语序，所以选B 7。B \\ \"她被安置在哪里，我们都不知道\\ \"，语序应该是表语语序。所以B 8。D“他做了什么与我们无关”与任何事都无关，句子是主语，谓语是单数，所以D 9。这是党号召我们做的事情。10.当它在从句中用作成分时，它是定语从句；如果它不在从句中作为成分使用，那就是同位语从句。11.一个12。B语序应该是陈述性语序，所以选B 13。你认为下学期谁会教我们数学？“你确定她诚实吗”，省略了15。他经常思考如何为四个现代化多做贡献。
