一、用作名词
表示“烦恼”、“苦恼”、“困难”、“困境”、“辛劳”、“辛苦”等，通常是不可数名词，使用时注意以下句型或结构：
(1) have trouble (in) doing sth 表示“做某事有困难”，其中的介词 in 在口语中通常可省略，但通常不能改用不定式。如：
我们没花吹灰之力就找到了他的办公室。
正：We had no trouble (in) finding his office.
误：We had no trouble to find his office.
(2) take (the) trouble to do sth 在这一结构中，其中的冠词用不用均可，但含义稍有不同：用冠词，表示不怕费事或不怕麻烦而去做某事；不用冠词，表示尽心尽力或费尽心血而去做某事。如：
He took the trouble to show me the way to the station. 他不嫌麻烦为我去邮局指路。
You might have taken the trouble to tell me the meetingwas put off. 你本来可以费心告诉我一声会议推迟了的。
They took a lot of trouble to find the right person forthe job. 他们费尽心血找适合做这项工作的人。
注：take trouble to do sth 有时也可说成take trouble oversth。如：
He took a lot of trouble over the design. 他花了许多工夫 设计这份图样。
根据以上区别，比较并体会以下正误句型：
他不愿麻烦去开门。
正：He refused to take the trouble to open the door.
误：He refused to take trouble to open the door. from www.yywords.com)
