【参考答案】
1.C 看到乌云遮盖了天空，他就停下工作回家了。现在分词做伴随状语，其逻辑主语是主句主语：he...主动语态，故C正确。B被动形式排除。选项A是不定式形式，表目的，将来要发生的动作，译为：为了要看乌云遮盖天空，他……显然不合题意。D.没有这种用法。
2. C 他在学习英语上有困难吗?have difficulty (in) doing为固定搭配，意为干什么有困难，其中in 可以省略。
3.A 冬季我们去山上滑雪。go skiing为固定搭配，意为去滑雪。
4.B 那个你刚才跟他说话的那个人是个美国人。先行词是指人，在句子中充当的是宾语(通过：you were talking to，我们看出句子缺少宾语。)，故用whom.
5.B 那个他曾经为之奋斗了终身的目标，看起来对他已经不再重要了。关系代词举代指The goals，在句子中充当宾语，句子中的谓语动词是：fought，“战斗，奋斗”的意思。是一个不及物动词，后面接宾语时要带上介词，fight for ，为……而奋斗;介词后面接宾语，表示物时只能用which来代替。
