牛津译林版英语9A Unit3 Teenage problems知识归纳与拓展
【句型分析】
1．I dream of a long holiday so that I could have more time for my hobbies．(P36)
句中的so that用来引导目的状语从句，常与may，can，will等连用，意为“为的是”，相当于“in order that”。如：
We turned on the light so that we could see what it was．
我们打开灯，以便看看它是什么。
I hired a boat so that 1 could go fishing in the lake．
我租了一条船，为的是可以在湖里钓鱼。
有时，在so that，in order that引导的目的状语从句中，当主从句中的主语一致时可以用so as to或in order to来改写为简单句，所以以上的两个例句也可以改写为：
We turned on the light so as to／in order to see what it was．
I hired a boat so as to／in order to go fishing in the lake．
但是so…that…表示“如此……以至于……”，引导结果状语从句。如：
Andy ran so quickly that we couldn’t keep up with him．
安迪跑得太快了．我们追不上他。
2．It seems that you spend a lot of time playing football．(P39)
句中的seem是连系动词，后面可接形容词作表语，意为“似乎或好像……”的意思。另外，seem作连系动词时，后面通常接动词不定式作为表语．当动词不定式是to be+形容词的时候，to be可以省略。如：
She seems(to be)hungry．她好像饿了。
All her attention is paid to her children and she seems to have little time for anything else．
她所有的注意力都在孩子身上，她好像无暇顾及其他的事情。
It seems that she is happy．=She seems(to be)happy．
她看上去很快乐。
另外，seem也可用于there be句型中。如：
There seems to be a knock at the door．似乎有人在敲门。
3．talk to your best friend when feeling sad and share your problems with her(P43)
when feeling sad是when you are feeling sad的省略句。当时间状语从句中的主语和主语的主语一致(这里共同的主语是you)，且从句中有be动词时．町以省略从句的主语和be动词。
While(I was)walking along the street．I heard my name called．
走在街上的时候，我听见有人叫我的名字。
Work hard when(you are)young，or you’ll regret．
少壮不努力，老大徒伤悲。
