she has taken care of your daughter since you are away
问题描述:
she has taken care of your daughter since you are away
这句话我觉得有问题.本题是个选择题,答案是选since,如上面写的,据我了解,since不是跟完成时联用吗?就本题而言,如果选since,后面该是过去式啊,为什么是一般现在时.
答
she has taken care of your daughter since you are away.自从你走后,她一直照看着你的女儿.‘take care of sb’固定词组,意为照顾、照料某人.这句句子就是现在完成时.完成时态一般形式即sb have/has/had done sth....
