that和where定语从句

　　定语从句，一个简单句跟在一名词或代词后进行修饰限定，就叫做定语从句。下面是小编整理的that和where定语从句，欢迎大家分享。

　　that和where定语从句的区别：

　　1.看被定语从句所修饰的先行词(名词/代词)能不能直接和从句相连.

　　如果可以直接和从句其他成分相连,无须补上介词,则用that/which;

　　如果需要额外补上介词才能放在定语从句中,则用where.

　　如：This is the city (which/that I stayed in last year).

　　把先行词the city放入后面的定语从句,为：

　　I stayed in (the city) last year.

　　the city直接做介词in的宾语,所以用which/that.

　　再如：This is the city (where I stayed last year).

　　把先行词the city放入定语从句,需要补上介词in方可,即为：

　　I stayed (in the city) last year.

　　所以使用where或in which.

　　2.看定语从句是缺少地点状语还是缺少主语/宾语/表语.

　　如果缺少地点状语,用where;

　　如果只缺少主语/宾语/表语,则用which/that.

　　如：This is the city (which/that) I visited last year.

　　从句I visited last year中,及物动词visited后面缺少一个宾语,所以用which/that;

　　再如：This is the city (where) I lived last year.

　　I lived last year中,缺少地点状语in the city,所以用where或in which

　　其实上面两种方法是一样的,不知道楼主能不能看明白?

　　限定性定语从句：

　　意义：

　　限定性定语从句对被修饰的先行词有限定制约作用，使该词的含义更具体，更明确。限制性定语从句不能被省略，否则句意就不完整，例如I met some one who said he knows you.

　　在引导限定性定语从句时，that有时相当于in which,at which,for which或on which

　　(1)Attitudes towards daydreaming are changing in much the same way that(in which) attitudes towards night dreaming have changed. 人们对白日做梦的态度正在改变，这与人们对夜间做梦的看法的变化有非常相似之处。

　　(2)I like the music for the very reason that(for which) he dislike it. 我出于某种原因喜欢这种音乐，而他恰恰与我相反。

　　(3)We arrived the day that(on which) they left. 刚好我们到的那天他们走了。

　　在限定性定语从句中，当关系代词在从句中担任动词宾语时，关系代词可省略。

　　(1)The book (that/ which) I am reading is very interesting. 我在读的书很有趣。

　　(2)Is there anything (that) you wanted? 想要什么东西吗?

　　非限定性定语从句：

　　意义：

　　非限定性定语从句起补充说明作用，缺少也不会影响全句的理解。在非限制性定语从句的前面往往有逗号隔开，如

　　(1)The house,which I bought has a lovely garden.　我买的房子带着个漂亮的花园。

　　(2)This novel, which I have read three times, is very touching. 这本我已经读过三遍的小说很感人。

　　1.非限定性定语从句可将整个主句作为先行词, 对其进行修饰,这时从句谓语动词要用第三人称单数，例如：

　　(1)He seems not to have grasped what I meant, which greatly upsets me.他似乎没抓住我的意思，这使我心烦。

　　(2)Liquid water changes to vapor, which is called evaporation. 液态水变为蒸汽，这就叫做蒸发。

　　2. 在非限定定语从句中，有时as也可用作关系代词，若as在从句中作主语，其引导的句子可以放在句首，也可以放在句中。例如：

　　(1)The boy has as much progress as we had expected. 正像我们所预料的那样，这个男孩取得了大的进步。

　　(2) As everyone knows ,China is a beautiful country with a long history . 每个人都知道，中国是一个有着悠久历史的美丽国家。

　　3. 在非限定性定语从句中，不能用从句做主语

　　(1)The boys ，who are playing football ，are from Class One. 在踢足球的男孩们是一班的。

　　(2)I helped an old man ，who lost his way ，yesterday . 昨天，我帮助了一个迷路的老人。

　　相关资料：

　　一、where引导定语从句时,where是关系副词,在从句中作地点状语,其前面有表示地点的先行词。

　　where引导的从句修饰先行词，例如:

　　The bookshop where I bought this book is not far from here.

　　This is the house where I lived two years ago.

　　We will start at the point where we left off.

　　二、where引导状语从句时,where是从属连词,where引导的从句修饰主句的谓语动词,

　　where前面没有表示地点的先行词，例如:

　　Wuhan lies where the Changjiang River and the Han Jiang Rivermeet.

　　Make a mark where you have any doubts or questions.

　　I found my books where I had left them.

　　有时,where引导的地点状语从句兼有抽象条件含义,可放在主句的前面,而where引导的定语从句则不能，例如:

　　Where there is a will,there is a way.〔谚语〕有志者事竟成。

　　Where there is water,there is life.有水的地方就有生命。

　　三、在有些情况下,where引导的定语从句可转换为where引导的地点状语从句，例如:

　　A tall building was put up at the place where there used to be a desert.（＝A tall building was put up where there used to be a desert.）在以前曾是沙漠的地方盖起了一幢高楼。

　　Bam boo grows best in places where it is warm and where it rains often.）温暖而多雨的地方最适合于竹子生长。
