Answer 1

1.She can't help ___ the house because she's busy making a cake.
A.to clean B.cleaning C.cleaned D.being cleaned
help (to) do,虽然有句型can't help doing 但是它是情不自禁做某事的意思，这里只说他很忙，没有时间帮忙，所以选A
2.The murderer was brought in,with his hands___behind his back.
A.be tied B.having tied C.to be tied D.tied
考察伴随状态，这里他的手是被绑的，故用tied
3.He dived_____into the river to save the girl and I was ___moved by his deed.
A.deep,deep B.deep,deeply C.deeply,deep D.deeply,deeply
deep可做副词，强调的是深度，deeply也可作副词，但多形容人的情感

2.选D,表示在进来时手就已被拷在背后了.
3.选D,当表示有具体的深时用Deep, 如表示抽象的就用deeply.

7.先D,announce一般不用被动时态.
8.B,found意为成立,学校成立了一个特别的班级以帮助那个知识贫乏的读者.
