根据句意及汉语提示，用短语的恰当形式完成下列句子
【小题1】I stayed up late （熬夜）yesterday, because there was lots of homework to do.
【小题2】To our surprise , （使我们吃惊的是）Tom who never learns English, got the highest score in the class in the first-month exams.
【小题3】He prefers to （更喜欢）stay at home rather than go out if let him choose.
【小题4】I have to set out to see a doctor because of （因为）headache now.
【小题5】We have succeeded in (成功) finishing the task that our boss asked us to do.

解析：【小题1】本题为昨天晚上熬夜，故使用一般过去时，stay up late表示熬夜的含义，故本题空格处填stayed up late。【小题2】本题的含义为令我们惊讶的是从来不学英语的汤姆取得了班级最好的成绩，to one’s surprise表示令某人惊讶的含义，故本题空格处填To our surprise。【小题3】本题的含义为他更喜欢待在家里，prefer to表示更喜欢的含义，故本题空格处填prefers to。【小题4】本题的含义为我因为头疼我得去看病，because of后跟短语表示原因，故本题空格处填because of。【小题5】本题的含义为我们成功的完成了我们老板所要求的任务，本题为现在完成时，succeed in表示在……成功的含义，故本题空格处填succeeded in。

我明天再问问老师，叫他解释下这个问题
