状语从句(二)

专题（十四）状语从句（2）

(五)原因状语从句

原因状语从句可由because, as, since, now that, in that, considering (that)等词引导。 1．because 译作“因为”，表示直接原因，语气较强，能回答由why 提出的问句。 The old man asked Lucy to move to another chair _________ he wanted to sit next to his wife. 那位老人让露西换坐到另一把椅子上，因为他想挨着妻子坐。

2．as 译作“由于”，语气较轻，常表示显而易见的原因；since (既然), now that (既然), in that (因为)，表示双方都知道的原因，语气较弱。as, since 和now that 引导的从句多位于主句之前。

________ you have got a job, you should learn to be independent of your parents. 既然你找到了一份工作，你应该学会独立不依靠父母。 (六)方式状语从句

引导方式状语从句的从属连词有as, as if, as though 等。方式状语从句应放在主句之后。其中as if 或as though 引导的从句常用虚拟语气，但如果从句中所陈述的情况很可能实现，也可用陈述语气。

①The house was greatly damaged by the truck.We’d better leave things ______ they are until the police arrive.

卡车对这座房子造成了严重的损坏。我们最好保持原样直到警察到来。 ②The construction industry is no longer as depressed _______ it was. 建筑业不再像以往那样萧条了。
