Earthquakes

er than Jack. 鲍博比杰克重一倍。
　　This road is twice longer than that one.这条路比那条路长一倍。
　　11.语法——定语从句
　　关系代词who, whom, that 和which引导的定语从句。
　　在句子中修饰名词或代词的从句为定语从句。定语从句所修饰的词叫先行词，定语从句一般修饰跟在先行词的后面。如果先行词指人，关系代词可用who, whom, that.如果先行词指物，关系代词可用which或是that。关系代词who, whom, that 和which既起连接作用，又在定语从句中充当一定成分（在定语从句中作主语或是宾语）。关系代词在从句中作宾语时常常可以省略，但是作主语时不能省略。Whom 在从句中作宾语时用，但是在口语或非正式文体中，常用who来代替whom。
例如：
　　A plane is a machine which/ that can fly.飞机是会飞行的机器。
　　The book (which/ that ) you want is on my desk.你要的那本书在我的书桌上。
　　Anybody who/ that breaks the rules is punished.任何违反规定的人都要受到惩罚。
　　The boy who/ that likes skating will be here.喜欢滑冰的那个男孩子将会来这里。
　　The girl (who/ whom/that) you met in the street is John’s sister.你在大街上遇到的那个女孩是约翰的妹妹。
　　Is this the lady (whom) you spoke of? 这个是你谈到的那位女士吗？
