1.教练,我是不是可以继续训练了?
不好意思,还不可以.因为你的膝伤还没恢复.
as是因为的意思.
2.虽然很热,我们还是睡得很熟,因为长途旅行太累了.
as 做“虽然”讲时,要用倒装结构.即:
表语+as+主语+谓语(若表语是单数名词,不用不定冠词)
状语(much)+as+主语+谓语
动词(try)+as+主语+谓语
3.Jenny 丢掉了在加拿大拍的照片非常伤心,因为这是一个她特别珍惜的回忆.
as同样是因为的意思.第一题不可以选B吗,翻译为你不能在。。之前选B的话后面就应该是yourecovered from the knee injury而不是you have not recovered from the knee injury 意思是“在你膝盖恢复之前不能继续训练”
