trouble(d)

1.说“努力”或“辛劳”只可用单数形式trouble，不可用复数形式troubles。take trouble里没有the，但take the trouble to...（不定式）里必须有the。例如：He was good enough to take trouble. 和He was good enough to take the trouble to open the door.

2.He was as well rewarded for his troubles as for his trouble是“他为了他的种种困难，正像为了他的努力一样，得到了充分的报酬。”就是说“他不曾白费力，也不曾白吃苦。”

3.谚语Never trouble trouble till trouble troubles you是“烦恼寻你没办法，总勿自去寻烦恼”。用作名词的trouble前面没有the。

4.The trouble is that we have not much paper left等句在口语里往往省去The，改作Trouble is that...

5.I had little trouble (in) getting the work done里的in可有可无。

6.I am troubled with chilblains和I am troubled by chilblains都可以说。

7.关于a troubled look（一个烦恼的神情）等，参见much 3 (5) E
