_______ maths is the base of all other sciences.
A. That is because B. That is that
C. It is that D. Because

我怎么感觉A D都可以啊
because那个题目
如果是回答一个问句:why did u spend so much time on maths?
用D回答不就很合适吗? 这时候用A和D的不同就在于 A更强调了一下(my opinion)

I wish I ________ yesterday’s exam.
A. passed B. had been able to pass
C. were able to pass D. could pass

A.如果用D,后面还应该有句话,否则不完整

D.

要根据语境来选择,
A: 那是因为数学是其他科学的基础

D: 因为数学是其他科学的基础
从语法上来说,这两种说法都正确.

2.B
wish 后面跟过去完成时

1.A
2.A

应该选A吧,如果选d的话应该加个冠词the,我是这样认为的

A:

D:

第一题为A
第二题为D(wish引导的从句通常用虚拟语气,即could pass)
