（二）限制性定語從句和非限制性定語從句
區別：（1）限制性定語從句與其先行詞關系密切，如果去掉該從句，剩余部分的意思不完整甚至失去意義；非限制性定語從句只是其先行詞的附加說明，如去掉，句子剩余部分意思仍然完整。
（2）限制性定語從句與其先行詞之間不用逗號隔開，非限制性定語從句與其先行詞之間一般用逗號隔開。
（3）限制性定語從句的先行詞一般為單個的名詞或代詞；非限制性定語從句的先行詞既可以是單個的名詞或代詞，也可以是整個句子或其中一部分。
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：非限制性定語從句不能用that來引導。
The team is headed by a 44-year-old Mongolian, whose wife is a Tibetan.
昨天，布朗先生參觀了杭州，它因為西湖而聞名。
Yesterday Mr. Brown paid a visit to Hangzhou, which is famous for its West Lake.
他們邀請我訪問他們國家，真是太謝謝他們了。
They have invited me to visit their country, which is very kind of them.
（三）由as引導的定語從句
as可作為關系代詞和關系副詞來引導定語從句。
1. such … as… “像…一樣的”，“像…之類” the same…as…“和……同樣的”
Such people as you say are short now.
This is the same thing as we are in need of.
先行詞被the same 修飾時，關系代詞既可用that, 也可用as，但意義不同，前者表示“同一的”，后者表示“同樣的”。
2. 引導非限制性定語從句，指代整個文句的內容。表“正如……”。
as was mentioned，as you said, as has been reported
注意事項
what不引導定語從句
I want to give you what I have. （賓語從句）
（四）反意疑問句
一般用于口語英語之中，以較禮貌的形式來展開一次對話，提出一個要求，請求對方的同意或肯定一種說法。
1. 前肯定后否定，前否定后肯定
2. 前后兩部分在時態、人稱、和數上要保持一致。
注意：
1. 當前句中有few, little, hardly, never, seldom等否定含義的詞時，附加問句要用肯定形式。
2. 當前句為祈使句時，反意疑問句常用 “will you”
3. Don’t forget to phone me, will you?
4. 前句部分為主是Let’s用來表示提出建議，反意疑問句用shall we? 若用來表允許，反意疑問句常用will you?
5. 前句謂語動詞是there be, 反意疑問句仍用there be形式。
6. 在英語口語中，陳述部分若以I am開頭，反意疑問句用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?

【短詩欣賞】
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.
