七、方式状语从句
方式状语从句是描述动作方式的从句。方式状语从句常由 as ,as if as though 等词引导,通常位于主句之。
a . as ,just as
这两个连词的意思是如,正如一样。 just as 比 as 语气要强一些。
do in Rome as the Romans do .入乡随俗。
Leave things as they are .让一切顺其自然。
Please do as you are told .请按照人家告诉你做的去做。(也可说 Please do as told .)
Balloons float in the air just as boats do on the sea .气球在空中就如同船浮在海面上一样。
注意:
在口语中,还可用 like 来代替 as ,引导一个方式状语从句。
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。
do you make bread like you make cakes ?你做面包的方法是不是和做点心一样?
B . as if ,as though
由 as if 或 as though 引导的状语从句可以用陈述语气表示可能符合事实的情况,也可以用虚拟语气的过去式表示现实不符的或与事实相反的情况。
She looks as if she is ill .看上去她好象是生病了。
The boy plays piano as though he has a natural ear for music .这孩子弹起钢琴来家好象天生很懂音乐似的。

用于同等程度级的比较。否定句用 not so/as as ,not the same as 。

B . than
than 表示不同程度级的比较

注意:
在比较从句中通常把和主句重复的部分省掉,如果把省略部分补上,而显得累赘或不合乎习惯。
