D.if Sally will help us ,if she helps us
可是为什么其他选项是错的

Answer 1

1.since 有因为、既然的意思,表示说话人无奈的语气,“既然下雨了,那我们最好还是就呆在家里看看书吧.”
For和Because只能单纯表示因为,though 则是尽管,表示让步,语义上不通顺.
2.I wonder表示我在想什么事情,if和whether都表示是否,if表示说话人期望得到肯定回答,whether则不一定,题中的作者其实是希望得到别人帮助的,所以应该用if;
第二空用一般现在时做条件状语,条件状语中的动作只强调动作本身,不考虑时态；比如：
I'll ask him to call you when he comes back.他一回来我就会叫他打电话给你.(实际上说话的当下他还没有回来,他回来这个动作一发生,我将会叫他打电话给你.)
