6. dozen 打；十二个
Pencils here are sold by the dozen . 这里的铅笔论打出售。

7. height 高；高度
The Party calls on us to climb the heights of science and technology . 党号召我们攀登科学技术高峰。
〖点拨〗in height 从高度上看。What’s the height of …? ……的高度是多少？如：The building is 40 metres in height . = The building is 40 metres high .= That’s a 40-meter-high building .
8. mention 提到；说起
Did you mention this to your parents ?

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

〖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……。

1. get in 进去，进来；收进来；收庄稼
