Answer 1

1. I really don't konw ___.they are all very beautiful.
A.which ong should choose B.which one to choose C.to choose which one
答案选B：“疑问词+不定式”结构相当于一个名词短语，做know的宾语。
该结构的具体解释请参看我的另一答案：http://zhidao.baidu.com/question/57169770.html

2.Mr paul is a good teacher He often has a strange way___making hia classes ____
A.of; live B.to ;live C.of; lively D.to ;living
答案选C：固定结构the way of doing sth或the way to do sth “做某事的方法”； lively adj. 生动活泼的

3.No one enjoys ___ at.
A laughing B to laugh C to be laughed D deing laughed
答案选D：enjoy doing sth，排除BC；而句意是“没有人喜欢被嘲笑”，后面用被动，所以就变成了enjoy being done。

4.Each of our English classes begins with ___talk.
A.an every day B.daily C.an everyday D.five-minute
答案选C：talk在此句是可数名词，需要冠词，排除BD；everyday adj. 每日的，日常的；every day是个副词短语，在句中充当时间状语，而不能充当定语去修饰名词。

5.Mable was ___ill__she had to be taken to hospital at once.
A.so;so B.so;that C.such;that D.such a;that
答案选B：固定句型so...that... “如此...以致于...”；而such是形容词，要修饰名词，但ill不是名词；so才是程度副词，修饰形容词和副词（象very一样，ill是个形容词）。

Answer 2

1.I really don't konw ___.they are all very beautiful.
A.which ong should choose B.which one to choose C.to choose which one
应选B，这是疑问词加不定式结构，疑问词必须放在不定式之前。
2.Mr paul is a good teacher He often has a strange way___making hia classes ____
A.of; live B.to ;live C.of; lively D.to ;living
应选C，a way of doing sth或者是 a way to do sth这里已经有了making只能用of ，第二个空，lively是活泼的，生动的。 其他的不合适，living是有生命的，live是活着的，现场直播的，
3.No one enjoys ___ at.
A laughing B to laugh C to be laughed D deing laughed
应选D，enjoy后需用doing形式，这里是被讥笑，而不是讥笑别人，应该用被动形式。
4.Each of our English classes begins with ___talk.
A.an every day B.daily C.an everyday D.five-minute
应选C，everday是日常的，every day 是每天，作副词用，daily是每日的，talk这里是可数名词。表示一次谈话。
5.Mable was ___ill__she had to be taken to hospital at once.
A.so;so B.so;that C.such;that D.such a;that
应选B，so...that如此……以致……，so后用形容词，such后用名词，这里ill是形容词，当然要用so了。
