请教为啥要选这个答案`````

答案

1.It is late into the night.All____quiet in the street.
A.is B.was C.will be D.are (选A)
B和C错在要和前面的时态一致 d错在 all指的是街上的所有的环境 是不可数的
2.He____about something.
A.always was complaining B.complained always
C.always complained D.was always complaining (选D)
be always doing 是一种特定的用法 表示这个人一只这样做
3.They left foe Beijing last week and we ___ them .
A.don't hear from B.haven't heard from
C.didn't hear from D.won't hear from (选B)
看到so far就要用完成式 表示至今为止
4.Sorry,I____you____here.
A.don't know;are B.hadn't thought;are
C.think;were not D.didn't know;were (选D)
a时态错了 既然说了这句话 就表示在说这句话之前我认为它不再这 所以要用过去式 B错在 think 没有完成式 他是瞬间动词 C错在 象think 一类的词 否定词要在think 的前面
5.When I arrived,the Browns ____ supper.
A.was having B.have had
C.had had D.had (选C)
a错在the browns表示brown一家人 式复数 b错在我倒那里已经是过去式了 那么在我到之前他们吃应该是过去完成状态 d错在他的had是吃的意思 时态没有 c的第一个had 表示过去完成时态 后一个表示吃
6.The Brown______a lot
A.has changed B.was changing
C.had changed D.has been changed (选A)
见到since就要用完成式b就错了
d表示brown一家被改变 错了 不能用被动
自从我1980年到那里之后 他们变了很多 是持续到现在的 不能用过去完成
