1.He did not want to go( ).

2.What courses are you going to do next semester?
I don’t know. But it’s about time( )on something.
A.I’d decide B.I decided C.I decide D.I’m deciding
答：B
译：你下学期打算学什么课程?
不知道.不过,我该作出决定了.
析：本题考查一个虚拟语气句型：
It is (about/high) time (that) sb. did (/should do) sth.
注意：从句用一般过去时或should +V. , 与虚拟10动词（insist, suggest, advise, order, ...etc.)的宾语从句中should +V 不同的是,这个句形中的should不可以省略!请不要迁移混淆!
3.The stubborn young man did not follow the advice that he ( )
on his behavior since he refused to believe he had done anything wrong.
A.reflect B.had reflected C.would reflect D.must reflect

答：A
译：这个倔强的年轻人不听人家要他反省自己的行为的劝告,因为他拒不承认他做错了什么.
析：当虚拟语气10动词之一的advise改用名词advice时,其同位语从句谓语动词也要用虚拟语气（：should +V, 考试时常将should省略）
4.People came to fish the streams,which flowed( )out of the hill
A.clear and cold B.clearly and coldly
C.clearly and cold D.clear and coldly
答：A
译：人们来这些溪流中钓鱼,这些溪流清澈冰凉,从那小山中缓缓流出.
析：本题考查形容词（短语）作主语补足语.B项是干扰项,容易以为是副词作状语修饰谓语动词flowed的,人们可以say sth. clearly, 可以look at sb. coldly, 河水可以slowly 地flow, 但不会clearly and coldly地flow, 这个放进句子不符合逻辑.所以排除B.CD本身乱了,凑数项.

D one or another表示某种, 这样或那样
C it is about time that I (should) do something. 这里省略了should
A 这里的情况跟第二题一样
A这道题里的steam应该是stream吧，人们上河里钓鱼，这条河从山里出来，河水又清又凉，形容水，不形容flow，所以是形容词。
希望能帮到你谢谢，但是第四个题...

1. D 由于某种原因。这个原因或者那个原因或者那个原因，C是不正确的。AB，一个和其他很多原因，想想厂里也是不通顺的。再者D可以当成一个固定用法短语。
2. B it is about time +过去式，虚拟语气，该干。。。的时候了
3. B 用过去时
4. A coldly是冷淡的不友好的，意思不符合。clear，清澈的。...
