引导比较状语从句的连词有:than; as...as; not so as...as; the+[JP]比较级,the +比较级。引导方式状语从句的连词有:as, as if, as though等。在非正式英语中,like也可用来引导方式状语从句。如:
She is doing the work exactly like I want her to. 她正在完全按照我要求她的那样在做这项工作。
【点津】1.从属连词as if, as though多表示一种假设,因此从句中的谓语动词常用虚拟语气。
She speaks as if she knew everything in the world. 她说起话来就好像知道天下所有的事一样。
2.在美国英语中表示"正如"、"像……"且后跟句子时,as与like通用。
Don’t talk to me like you talk to a child. 不要像跟孩子说话一样与我讲话。
You should do as I do. 你应像我做的那样去做。
