Answer 1

1.＿＿morning is the best time for world.When＿＿day breaks, We go to work.
A.A. a
B.The.a
C.A. the
D. *. *
==>选D。
第一个地方：不墒?抽象)名词泛指不用冠词，而当morning前面有形容词，一般用不定冠词，如：a sweltering morning(闷热的早晨)。
第二个地方：这里的day也是抽象名词，不可数，不能说days break,所以泛指时也是不要冠词的。

2.We had watched the girl sewing for some time before＿＿that she＿＿blind.
A.we knew^^^was
B.we knew^^^would have been
C.we would know^^^would be
D.we had known^^^had been
==>选B。
排下时间先后:她瞎了> 我们看着她 > 我们知道, 显然“我们知道”没有发生在过去的过去，没有更过去的时间作为参考，用过去完成时不妥。这样排除D。would有两种用法，一种是过去将来时的标志，另一种表示主观猜测或愿望，同时要用完成时，所以是would have been。而对于“我们知道”没有主观臆测的意味。

3.Policemen＿＿very busy.
A. nearly are always.
B.always are nearly.
C.always nearly are.
D.are nearly always
==>选D。
副词的排列顺序：
1.副词的排列顺序是指在一个句子中有多个副词时,一般要按情状副词、地方副词、频率副词、时间副词的顺序排列。
The man runs slowly along the river at six o'clock every morning.
这个人每天早上六点钟慢慢地沿着河边跑步。
2.副词和动词的次序：副词放在be或助动词之后，实义动词之前。这里是be动词。

Answer 2

b a d
1，第一个空是特指，需用定冠词the,第二个空是泛指所以用不定冠词a
2,主句是过去完成时，所以从句应用一般过去时，所以第一个空用过去时，后面的空必须与谓语动词knew一致所以用was
3,副词应放到be动词后面
