小题1:Those magazines don’t belong to us.

小题2:There are fewer days in February than in January. / February has fewer days than January.

小题3:His advice isn’t worth taking / following.

小题4: He has devoted himself to the English study. / He has put all his effort into the English study.

小题5:This morning that patient was operated on.

题目分析：

小题1:“属于”是belong to sb；根据题干，本句应该是一般现在时。故本题的答案是Those magazines don’t belong to us.

小题2:根据题干，本句是一个比较级，“更少”应是fewer。我们既可以用there be句型，也可以用have进行造句。故本题的答案是There are fewer days in February than in January. / February has fewer days than January.

小题3:“值得做某事”是be worth doing sth；“采纳”是follow或take。所以本题的答案是His advice isn’t worth taking / following.

小题4:根据题干中的“已经”可知，本句应该是现在完成时；“全身心地做某事”有两种说法：devote oneself to sth和put one’s effort（heart）into sth。所以本题的答案是 He has devoted himself to the English study. / He has put all his effort into the English study.

小题5:根据题干，本句应用过去时；病人的手术应该是被动的，故用被动语态；“动手术”是operate…on。所以本题的答案是This morning that patient was operated on.

点评：对于汉译英的题目需要注意三点：一是注意时态语态；二是注意固定短语的用法；三是符合英语的表达结构。
