定語從句that和what的區別
一、引導詞what與that在引導名詞性從句的用法區別引導主語、賓語或表語從句時，what在從句中要充當句子成分;而that引導主語、賓語、表語和同位語從句時，不作任何成分，只起語法連接作用。試比較：
That George W. Bush won the presidency once again was what many people hadnt expected.喬治?布什再次贏得總統大選，這是很多人沒有預料到的。
It is the same old story of not being grateful for what we have until we lose it.事情往往是這樣，失去之物，方知珍惜。
二、引導詞what與that在引導定語從句的用法區別首先，要記住在定語從句中，跟本不用what連接詞。只有that和which.所以大家在做題中，如果是定語從句，就不要再考慮what了。That 在定語從句中，一般可以作從句的主語。賓語和表語。例如：
1、(2005北京春季卷) Do you still remember the chicken farm ____ we visited three months ago?
where B when C that D what
「分析」C 定語從句連詞，that做從句visit的賓語。沒有what連詞。
2、He is not the naughty boy that he used to be.他不再是從前那個調皮的男孩了。
鞏固性練習：從A、B、C、D四個選項中，選出可以填入空白處的最佳選項。
1. (2005福建卷) --Is that the small town you often refer to?
--Right， just the one _____ you know I used to work for years.
A that B which C where D what
2. ____ should be done must be done in time.

1. C 定語從句，one是先行詞
2. A what引導主語從句，做從句中can的主語。這里what=all that
3. C so……as……連用，屬于定語從句的范圍。
4. B 定語從句，whose從句effects的定語
5. D 非限定性定語從句，沒有that 和what.
6. B 第一空是of的賓語從句，從句中have缺少賓語，因此用what做連詞。第二空something后面是定語從句。
7. C 主語從句連詞 "父母的所作所為對孩子有終身影響"
8. B主語從句連詞，從句中refer to缺少賓語
9. D 是do的賓語從句
10. D 是介詞at的賓語從句，at 做was 的主語。I think是插入語，可以忽略。
what和that的區別：
一、表達的內容不同：
what：作代詞時意為“什么;多么;多少”，作形容詞時意為“什么;多么;何等”，作副詞時意為“到什么程度，在哪一方面”，作感嘆詞時意為“什么;多么”。
that：那，那個，那人，那事，那東西
二、作用不同：
what可以做代詞、形容詞、副詞、感嘆詞。
that在英語中使用廣泛，可用作形容詞、代詞、連詞、副詞，還可用于固定搭配。
三、引導從句的方式不同：
what引導名詞性從句時都在從句中充當句子的某一成分，如主語、表語、賓語或定語。
其區別是：what表示泛指的事物，常譯為"什么"或"所……的事物"，whatever是它的強語勢"無論什么"。
that可做連接詞：
1、引導名詞性從句：He expressed the hope that we would keep in touch with his firm.
翻譯：他表示希望我們與他的公司保持聯系。
2、引導狀語從句，表示原因或理由：We are glad that we have accomplished another arduous task.
翻譯：我們都感到高興因為又完成了一項艱巨的任務。
3、引導狀語從句，表示目的或結果)為了，以至于：He is working hard that he can catch up with the class.
翻譯：他努力用功，以便趕上班上同學。
4、引導表示愿望，感嘆的從句，主句常省略：That I could stay at home today!
翻譯：今天要是我能呆在家里多好呀!
