1.A,选for是对于的意思,你可以类比,比如：the question is too difficult for us.
后面的still是修饰比较级的,意思是更,翻译为比我几年前来这更冷.
2.C.本题考查交际用语.当对方表示感谢时,常用的答语有：You're welcome. / It's nothing. / That's all right. / Don't mention it. / It's a pleasure. / It's my pleasure. / That's nothing. / It was no trouble at all. 等.A项意思为“乐于效劳”；D项表示同意等；B项“不要紧. 没关系”.
3.A.这里省略了 I had thought,完整的为I didn't expect it was as I had though wonderful.我没有想到它如我想的那么精彩.
4.C. without
例句：Please don't leave without me.
请让我和你一起去.
A. except, 除.以外
B. but 通常与not这种否定句子连用
D. Besides 除..以外,还有..
A也是表示除.之外,但有主动的意味,似乎jack是自己不要去的,不符合.
