二道英语题目 说明理由 谢谢

1. The number of children who contracted colds and visited the hospital _______ in the county since last fall.
A. increased B. would contracted C.has increased D. had increased
2. Talking of different cultures，we must admit the fact that people from different cultures have ______ in common than we usually realize.
A. much B. many C. nothing D. more

Answer 1

第一题选C 句子主干：The number of children has increased in the county since last fall.
since last fall：自从去年秋天到现在为止，
这个时间状语与现在完成时态连用，因为主语the number是单数，所以选C
其中 who contracted colds and visited the hospital 是定语从句，修饰 children
第二题选D
“than we usually realize”
这个比较结构就暗示了用比较级

追问

请问第一题 为什么不选D contracted是过去式啊
第二题为什么不选A 呢
请解释一下 谢谢

追答

since last fall：自从去年秋天到现在为止。用现在完成时态，因为是到现在
第二题：than，需要比较，所以用more
