2.The bread will dry out if it is left on the table.如果把面包放在桌子上,它会变干的。
3.Dry hair can be damaged by washing it too frequently.干性头发洗得太频繁可能会受损。
◎用法总结:1.dry可作形容词,意为“干燥的,雨少的”。
2.dry作形容词,还可译为“干性的”。

2.We should prepare for drier weather.
[命题点二]even though的用法 　
●Even though tree planting is very difficult, they love their work.虽然树的栽种非常困难,但是他们喜爱他们的工作。
◎观察思考:1.He went out even though it was raining.尽管在下雨,他还是出去了。
2.Even though it's hard work, I enjoy it.虽然工作艰苦,但我还是很喜欢。
◎用法总结:1.even though意为“虽然,尽管”,引导让步状语从句。引导的从句可放在句首,也可放在句末,但不与but用在同一个句中。
2.even though引导让步状语从句时,可以与though与although互换,三者用法基本相同。
易错辨析
even though 和 even if均可用于引导让步状语从句,但用法有区别:
1.even if 引导的从句往往是假设性的,相当于汉语的“即使”“纵然”“就算”“哪怕”。如:
They'll stand by you even if you don't succeed.即使你没有成功,他们也会支持你。
2.even though 引导的从句内容往往是真实的,主要用于引出不利于主句情况的信息,相当于汉语的“尽管”“虽然”。
对点自测
用even though和even if填空
1.　　 he has the least experience, he's the best teacher.
2.　　 it rains tomorrow, we won't change our plan.
【答案】
1.Even though
2.Even if
