大学英语语法句子成分
关系代词
<例句>
I met someone who said he knew you.
我遇到一个人，他说他认识你。
<语法分析>
关系代词 who 代表 someone，又引导从句修饰它，同时又在从句中担任主语。关系代词 who, whom, whose, that和which可以用来引导定语从句，这类代词都起着三重作用，一是代表前面的名词，二是把从句和它所修饰的词连接起来，三是在从句里也担任一个成分。who 和 whom都代表人，who 在从句中作主语，whom在从句中作宾语或介词宾语。whose在从句中可以作定语。that可以代表人或物，which只能代表物在从句中可充当主语、宾语或介词宾语等。
<触类旁通>
(1) The noise that she made woke everybody up.
她弄出的声音把大家都吵醒了。
语法分析：that 代表 noise，又引导从句修饰它，在从句中担任 made 的宾语。
(2) She saw something in the paper which might interest you.
她在报纸上看到的一些消息，或许会使你感兴趣。
语法分析：which 代表 something, 又引导从句修饰它，在从句中担任主语。
(3) The girl with whom I was travlling didn't speak English.
和我一起旅行的那个女孩不会讲英语。
语法分析：whom 代表人，在从句中作宾语或介词宾语。
(4) I saw a film whose name I have forgotten.
我看了一部电影， 名字却忘了。
语法分析：whose 有时指无生命的东西。
(5) Who's the man (that) you were talking to?
刚才和你讲话的人是谁?
语法分析：在从句作宾语时，that常可以省略。
(6) The situation in which she found herself was very difficult.
她的处境非常困难。
语法分析：在紧跟介词时，只能用which，不能用that，而且不能省略。

不定代词some的意思是表示“一些”，可以用来指人或其他可数的东西，也可以用来表示不可数名词的东西，它在肯定句中用作主语、宾语、定语等。在这个句子中，some和单数可数名词连用，其意义是表示“某个”，这与certain的意义相同。
<触类旁通>
(1) Some of them can speak English.

语法分析：简单用法。

这些苹果我拿些可以吗?
