1.An earthquake ______ 5.6 on the Richter scale hit Mianzhu City ,in southwest Chian's Sichuan Province at 2:03 am June

第一题：
这里主干是An earthquake hit Mianzhu City.然后中间的东西是非谓语动词放在名词后面充当定语,而做定语的时候,是看非谓语动词和被修饰名词之间的关系的.主动用-ing形式.被动用-ed形式.
这里名词是an earthquake,动词是measure.你看地震和测量是什么关系.显然地震应该是被测量的,不可能地震主动的去测量,所以用-ed形式.
第二题：
题目的意思是尽管他很富有,但他对穷人没有同情心.
这里考察的是as引导的让步状语从句解释为“尽管”的时候,放于句首句子倒装.一般as前面可以有adj/n/v,并且名词是零冠词的.
e.g.1:clever as he is,he still works hard.
2:boy as he is,he is very brave.
3:succeed as he might,he still works hard.
当然像上面说的尽管还有很多,比如though,although.这些连词其实他们是可以倒装也可以不倒装.我们一般是用不倒装的结构的.
上面as的用法考得最多的,也是错误率最高的还是第二种,它经常会在boy前面加一个a 来诱惑你,其实是绝对不行的.
“第一题我选 measuring 就等于 which measured 啊,如果选 measured 就少一个 which ,答案是错了吧”
这个加不加which是完全不一样的,因为,which加了以后就是一个定语从句,这里如果用定语从句应该是which was measured ,而不是你想的which measured.因为which指代的是the eartuquake,就相当于the earthquake was measured.
其实所有的非谓语动词都是从相应的从句转化而来的.做定语就是从定语从句中转化过来,状语就是从状语从句中转化过来,关键就是看这个动词在从句中是主动还是被动,主动的,在非谓语动词中,考虑用-ing形式.被动的就考虑用-ed形式.
比如题目中：
An earthquake (measured 5.6 on the Richter scale) hit Mianzhu City
=An earthquake ( which was measured 5.6 on the Richter scale) hit Mianzhu City
因为从句中用被动,所以在非谓语动词中也用被动形式.如果是主动的,应该也用主动形式.
e.g.the man who （is smiling 主动 ） to you is my uncle
= the man （smiling主动 ） to you is my uncle
those people who （were killed 被动 )in the war were very brave.
= those people (killed 被动 )in the war were very brave.
现在懂了吗?这个which有和没有是完全不一样的.
