Answer 1

1.on; for
on earth=究竟
stand for=代表
这句甚至都不用翻译就能填上,是2个短语动词
2.b
这句我做也犯难
没办法,查了查朗文词典,查到下面的解释和例句
double5
twice as big,twice as much,or twice as many
double the amount/number/size etc
We'll need double this amount for eight people.
The value of the house is double what it was.
3.c
appreciate 后面一定是动名词,appreciate=欣赏,赞赏
4.c
这句主要是考察not knowing的,d排除了,因为不是句子,a排除了,因为a表示将来,b排除了,不管意思是什么,not在having后面就不对,再加上意思是“已经不知道”或“不知道”更不对了,“知道”不适合用完成式
