8. mention 提到;说起 Did you mention this to your parents ? 〖点拨〗As mentioned above .如上所述。Don’t mention it . (答复别人道谢时的用语) 不必客气。Not to mention = without mentioning 更不必说。 9. length 长;长度;一段 What’s the length of the Yellow River ? 〖点拨〗注意 length 的发音。in length 从长度上看。如：The road is 5,000 metres in length . a length of pipe 一节管子。It was said that this kind of medicine could increase the length of life . 10. attempt 试图;尝试 They attempted to raise money for a new building . 〖点拨〗attempt 不强调成功性，而try 暗示可能有成功性。attempt to do = try to do = do one’s best to do 尽力干…… 。make an attempt to do = make an attempt at doing 试图干……。 单元词组思维运用 1. get in 进去，进来;收进来;收庄稼 Please hold the car door open for the old lady while she gets in .
