限制性与非限制性定语从句关系代所有格 限制性定语从句与非限制性定语从句的区别 非限制性定语从句：先行词为专有名词（如人名Tom、地名Africa）及独一性名词（如father），之后若接关系代词所引导的定语从句时，该关系代词之前一定要置逗号。此时该定语从句称为非限制性定语从句。 例. He has just come back from New York, which is a very big city in the United States。（他刚从纽约回来，那是美国的一座大城市） 限制性定语从句：先行词为一般名词且未具特殊性，可用定语从句加以限制，以加强其特殊性。翻译时先译定语从句再译先行词。 例. He is a boy who works hard. (他是位很用功的男孩) 例.I like the book which he bought yesterday.(我喜欢他昨天买的书) 初一英语练习题 英语单词记忆 英语语法练习题 注意 A.在限制性定语从句中，若关系代词为及物动词的宾语，则该关系代词可以省略。 例. I like the book which he bought yesterday | like the book he bought yesterday. B.限定性定语从句中，关系代词为主语时，可简化为分词短语。 法则是:删除关系代词，之后的动词变成现在分词(若为be动词直接省略) 例. The girl who dance here yesterday is my sister The girl dancing here yesterday is my sister 关系代所有格 关系代词所有格乃是人称代词所有格（his,your,their,its等）变化而成，和关系代词一样引导定于从句，修饰前面的名词。 例1：She has an uncle whose name is Peter 例2：I like that house, whose location looks good to me 从上面的例子可以看出，Whose可以代替人或物，引导定语从句，修饰前面的名词。 关系代词所有格使用要遵循以下两耳原则： 第一是关系代词所有格之前必须要有先行词 第二关系代词所有格之后的名词要做定语从句中的宾语或者主语，否者该关系代词所有格之前要置介词。 例1．I hate john, whose words are seldom true(我讨厌约翰，他说的话几乎是假的)。Whose words之前有先行词John，且作从句的主语，所以此句正确。 注意 之前小皮说过Whose可以代替人或物，但代替物时: whose + n.可用the +n. + of which或of which + the +n.代替。 例. I like study in this school, whose faculty and facilities are top-notch = I like study in this school, of which the faculty and facilities are top-notch . = I like study in this school, the faculty and facilities of which are top-notch . 翻译句子 1、昨天我们在街上看到的那个女孩是Tom的妹妹。 2.、他们种植一些不需要很多水的树。 3、今天早上我们买的那条鱼不够新鲜。 4、打破窗户的那个男孩叫Jim。 5、上个星期我去看了在 地震中失去丈夫的那位老师。 6.、窗户朝南的那个房间是我的 答案 1  The girl whom we saw in the street y esterday was Tom’s sister. 2  They planted some trees which did not need much water. 3  The fish which we bought this morning were not fresh enough. 4  The boy who broke the window is called Jim. 5  Last week I went to see my  teacher whose husband lost his life in the earthquake.
