第2题：

The drivers complain that the road sign is not easy to read;therefore,they suggest the words on it be made to stand out.

A:stick out
B:unusual
C:undamaged
D:unstable

答案：A
解析：
本句意思是：司机们抱怨路标很难认，因此他们建议让上面的字更突出。句中stand out意为“显眼，引人注目”，如：Grammatical errors are always obvious to me , spelling mistakes stand out.语法错误对我来说总是非常明显，而拼写错误也很显眼。四个选项中stick out意为“突出，显眼”，例如：The central part of the painting stuck out for its bright colour.这部绘画的中央部分因色彩明亮而夺人目光。unusual意为“不经常的”，如：Her voice was imbued with an unusual seriousness.她的声音里充满一种不寻常的严肃语气。undamaged意为“未受破坏的”。unstable意为“不稳定的”，如：The political situation remains highly unstable.政局仍然十分动荡。只有选项A同句中画线词语含义接近。
