【语法难点精析之被分隔的定语从句】
定语从句一般紧接被它所修饰的先行词;但有时候它和先行词之间有可能插入其他成分,使它与先行词分隔开来,这种定语从句叫作被分隔的定语从句,在阅读文章时会经常遇到这种情况,在阅读是要注意识别先行词的修饰对象。
一般说来,定语从句被分割开来大致有以下三种:
①在先行词与定语从句之间插入一个状语。
如:There are many thousands of stars in the sky that are like the sun.
在太空中有成千上万的象太阳般的星星。
乍一看,that引导的定语从句在名词sky的后面,似乎应该是修饰sky的。但仔细一想,”不对啊,天空怎么能象太阳呢?“,原来that引导的定语从句被in the sky这个地点状语分隔开来,修饰中心词stars。
②在先行词与定语从句之间插入一个定语。
如:Do you remember one afternoon ten years ago when I came to your house and borrowed a diamond necklace?
你还记得吗,十年前的一天下午,我来到你家,找你借了一条钻石项链?
when I came to your house and borrowed a diamond necklace实际上是修饰afternoon而不是修饰 years。ten years ago 实际上是定语后置修饰afternoon。
③先行词与定语从句被谓语分隔开来。此时,先行词通常是句子的主语,因定语从句较长,主句谓语较短,为使句子平衡,常将定语从句移至谓语之后
如:A new master will come tomorrow who will teach you German.
明天,新(男)老师将来较你德语。
【语法难点精析之besides,but,except,exept for,excepting,apart from的区别】
(1) besides与except
前者表示"除...以外,还有...";后者表示"从整体中除去..."
这个大家都知道,就不举例子了.
(2)except与except for
a.除去的和非除去的是同类事物,用except
eg:

Nelson的文章(除去的)和All the essays(非除去的)是同类事物,所以用except.
b.除去的和非除去的不是同类事物,用except for,并且从语气上通常表示遗憾.
eg:His essay is well written except for a few spelling mistakes.
a few spelling mistakes(除去的)和His essay(非除去的)是不同类的事物.
(3)apart from 具有多重意义:既可表示besides,也可以表示exept或exept for,还可以表示without的意思
eg:
Apart from the cost,it will take a lot of time.(=besides)
The orphan had no one to take care of him apart from his uncle.(=except)
He has done good work,apart from a few slight faults.(=except for)
