填空
he is not a pilot, but he wishes he____(be)
1.D 2.B
It is important/necessary/strange/anxious/surprised/determined+that···,这些句子的从句都习惯性用
（should)+动词原形 虚拟,should可以省略,所以是D.
2.原因同上
3.D
exercise当练习题/操（体操/眼操等）讲,是可数的,其余意思比如锻炼啊都不可数.
这题第一个空表示锻炼,第二个空表示习题,所以选D.
wish后可以接虚拟,但不是should do 的结构,一般虚拟语气的be动词都是were.
所以填空填were
