（二）限制性定语从句和非限制性定语从句
区别：（1）限制性定语从句与其先行词关系密切，如果去掉该从句，剩余部分的意思不完整甚至失去意义；非限制性定语从句只是其先行词的附加说明，如去掉，句子剩余部分意思仍然完整。
（2）限制性定语从句与其先行词之间不用逗号隔开，非限制性定语从句与其先行词之间一般用逗号隔开。
（3）限制性定语从句的先行词一般为单个的名词或代词；非限制性定语从句的先行词既可以是单个的名词或代词，也可以是整个句子或其中一部分。
1. A man who does not try to learn from others can’t achieve much.
2. There’re many plays (that) I’d like to see.
3. This note was left by Xiao Wu, who was here a moment ago.
4. Tom didn’t finish homework yesterday, which made his mom crazy.
注意：非限制性定语从句不能用that来引导。
The team is headed by a 44-year-old Mongolian, whose wife is a Tibetan.
昨天，布朗先生参观了杭州，它因为西湖而闻名。
Yesterday Mr. Brown paid a visit to Hangzhou, which is famous for its West Lake.
他们邀请我访问他们国家，真是太谢谢他们了。
They have invited me to visit their country, which is very kind of them.
（三）由as引导的定语从句
as可作为关系代词和关系副词来引导定语从句。
1. such … as… “像…一样的”，“像…之类” the same…as…“和……同样的”
Such people as you say are short now.
This is the same thing as we are in need of.
先行词被the same 修饰时，关系代词既可用that, 也可用as，但意义不同，前者表示“同一的”，后者表示“同样的”。
2. 引导非限制性定语从句，指代整个文句的内容。表“正如……”。
as was mentioned，as you said, as has been reported
注意事项
what不引导定语从句
I want to give you what I have. （宾语从句）
（四）反意疑问句
一般用于口语英语之中，以较礼貌的形式来展开一次对话，提出一个要求，请求对方的同意或肯定一种说法。
1. 前肯定后否定，前否定后肯定
2. 前后两部分在时态、人称、和数上要保持一致。
注意：
1. 当前句中有few, little, hardly, never, seldom等否定含义的词时，附加问句要用肯定形式。
2. 当前句为祈使句时，反意疑问句常用 “will you”
3. Don’t forget to phone me, will you?
4. 前句部分为主是Let’s用来表示提出建议，反意疑问句用shall we? 若用来表允许，反意疑问句常用will you?
5. 前句谓语动词是there be, 反意疑问句仍用there be形式。
6. 在英语口语中，陈述部分若以I am开头，反意疑问句用aren’t I 或am I not。
Tom is right, ______ he?
Tom isn’t right, ______ he?
He has been to Beijing, ______ he?
He will get married, ________ he?

【短诗欣赏】
The Walk
You did not walk with me
Of late to the hill-top tree
By the gated ways,
As in earlier days;
You were weak and lame,
So you never came,
And I went alone, and I did not mind,
Not thinking of you as left behind.
I walked up there today
Just in the former way;
Surveyed around
The familiar ground
By myself again:
What difference, then?
Only that underlying sense
Of the look of a room on returning thence.
