别是：whose 的意思相当于 one’s，而 which 的意思则相当于 that 或 this。比较： 1. This is Mary, whose father we met last week. 2. Call again at 11, by which time the meeting should be over. 【分析】第1句用whose，whose father相当于 and her father；第2句用which，by which time 相当于 and by that time。 七、弄错定语从句中谓语动词的数 原则上说，定语从句中谓语动词的单复数应与所修饰先行词的单复数保持一致，否则就会出错。如： 谁那样说都是在说谎。 误：Anyone who say that is lying. 正：Anyone who says that is lying. 不算生病的，我们一共20人。 误：There are 20 of us, not counting those who is sick. 正：There are 20 of us, not counting those who are sick. 八、受汉语影响导致定语从句用词累赘或成分残缺 一方面，引导定语从句的关系代词与定语从句修饰的先行词表示同样的概念，因此，千万不从句可在定语从句中误加与先行词同义的代词；另一方面，也不能受汉语习惯的影响，省去定语从句中不该省略的必要成分。如： 他是一个人人都敬重的人。 误：He is a man that everyone respects him. 正：He is a man that everyone respects. 刚才给我们讲故事的那个人很有趣。 误：The man told us a story just now is very interesting. 正：The man who told us a story just now is very interesting.  定语从句是我们从初中开始学习的语法点。但是，初中学习的很浅，到了高中，从句成了学生需要克服的一大语法难关。小编在这里为大家整理了以上定语从句中的八个易错点，希望同学们可以仔细研读，可以清晰明了的掌握定语从句的用法。

有时也可能用过去完成时或一般现在时： It seems like years since we last met. 我们似乎几年未见面了。  I've had the hots for him ever since he came to college.  自从他来上大学后，我就对他春心萌动。 She had shared responsibility for her brother since girlhood.  她从句的从属连词与句还是个小姑娘的时候就分担起照顾弟弟的责任。 Yesterday he told me that he hadn’t eaten anything since Tuesday. 他昨天告诉我自星期二以来他一直未吃任何东西。   这几点关于时间状语从句的从属连词与句子的时态之间的规律，在使用时一定要多加注意哦，赶快收藏起来吧~

从句可分为9种，在这9种当中，又有一个非常重要的叫做原因状语从句。原因状语从句学了。 Since we have no money, we can’t buy it. 因为没有钱，所以我们无法买下它。 For引导目的状语从句表示原因但并它并不能说明主句行为发生的直接原因，而只是提供一些辅助性的补充说明。同时，for引导的并列句只能放于主句之后并且必须用逗号将其与主句隔开。 She seldom go outside, for she is old and weak now. 她很少出门了，因为她现在年纪大了并且变得虚弱。 原因状语从句中非常值得注意的一点是because 和so 不能同时出现在一个句子里，这一点与我们汉语的语言习惯正好相反，需要大家特别注意。剩下的就是一些零碎的知识点，希望同学们在记忆时能更加仔细认真。

状语从句指句子用作状语时，起副词作用的句子，可以修饰谓语、非谓语动词、定语、状语或整个句子，可分为时间、地点、原因、条件、目的、结果、让步、方式和比较等从句，是英语复合句学习的一个重点，在各类考试中都会经常出现，所以小编这次就来给大家讲解一下什么是状语从句。 1. 时间状语从句： 常用引导词：when, as, while, as soon as, before, after, since , till, until 特殊引导词：the minute, the moment, the second, every time, the day，the instant, immediately , directly, no sooner … than, hardly …when, scarcely … when instantly eg.I ran into the classroom as soon as the bell rang. 2. 地点状语从句: 常用引导词：where 特殊引导词：wherever, anywhere, everywhere eg.

You can go to London as long as you have passport. 7.让步状语从句： 常用引导词：though, although, even if, even though 特殊引导词： as(用在让步状语从句中必从句指句子用作状语时，起副词作用的句子，可以修饰谓语、非谓语动词、定语、状语或整个句须要倒装)，while，no matter …， in spite of the fact that, whatever, whoever, wherever, whenever, however, whichever, as if=as though eg. Though we are old, we still can do these by ourselves. 8. 比较状语从句： 常用引导词：as(同级比较), than(不同程度的比较) 特殊引导词：the more … the more … ; just as …， so…,no … more than; not A so much as B eg.

以是短暂的。 如：   Sometimes I watch TV as I am having breakfast．   4）when和while还可以是并列连词，意思分别是“就在这时”，“然而”。 如：   I was having a rest on the sofa when the telephone rang．   They were surprised that a child should work out the problem while they couldn’t .   注：并列连词when常用与以下句型中：   ①…was/were doing…when…（正在做…突然）    ②…was/were about to do…when…（刚要做…突然）   ③…was/were on the point of doing…when…(刚从句是一较大的语法项目，也是近几年高考题中常见的一个重要试点。 下面是着重为大家讲解：时间状语从句要做…突然)   ④…had just done…when….(刚一…就)   ⑤Hardly/Scarcely had…done…when…(刚一…就)    好了，以上就是关于时间状语中when, while, as区别的介绍，还请大家在平时勤加练习。

常可省略。例如： ·Aprosperity which / that had never been seen before appears in thecountryside. 农村出现了前所未有的繁荣。（which /that在句中作宾语） （二）关系副词引导的定语从句 关系副词可代替的先行词是时间、地点或理由的名词，在从句中作状语。 （1）关系副词when,where, why的含义相当于“介词+which”结构，因此常常和“介词+which”结构交替使用。例如： ·Thereare occasions when（on which）onemust yield. 任何人都有不得不屈服的时候。 ·Beijingis the place where（in which）I wasborn. 北京是我的出生地。 ·Is thisthe reason why（for which）herefused our offer 这从句是指在句中做定语作用，修饰句中的名词或代词的从句，其中被修饰的名词或代词为先行词。当关系代词作定语从句就是他拒绝我们帮助他的理由吗 （2）that代替关系副词，可以用于表示时间、地点、方式、理由的名词后取代when,where, why和“介词+which”引导的定语从句，在口语中that常被省略。例如： ·Hisfather died the year（that / when / in which）he wasborn. 他父亲在他出生那年逝世了。 · He isunlikely to find the place（that / where / in which）helived forty years ago. 他不大可能找到他四十年前居住过的地方。

面的单词books。这个句子其实是由两个句子合并而成的： 1）I have three books. 2）The red of those books is my favorite. 这两个句子中有共同的名词books，这样就可以合写成一个句子，此时就用到了定语从句的第二个作用：连接两个具有共同名词的句子。把第二个句子中的those books替换成能连接两个句子的关系代词which，这样就能产生了如下这个句子：I have three books, the red of which is my favorite.为了让整个句子更加紧凑就把of which提到books后面，进而形从句的作用 1.连接两个具有共同名词的句子。 【例】I have three books of which the red is my favorite. 【解析】这是一个很简单的句子，定语从句成了刚才的那个句子。 表示因果逻辑关系 【例】America and Americans were prosperous beyond the dreams of the Europeans and Asians whose economies the war had destroyed. 【解析】这句话中有一个定语从句是由whose来引导的，在翻译

 关系代词在定语从句中作表语时。 eg. Our city is not the one that it used to be. 5. 先行词被形容词最高级或序数词修饰时。 eg. This is the best place that I have ever been to. 6. 主句是who 或which 引导的特殊问句时。 eg. Who is the boy that wearing a red hat?       Which is the book that we need to read this week? 以上便是六种要用that来引导的限制性定语从句，大家都明白了吗？内容虽然看起来多，但却是有规律可循的，所以只要抓住核心，将难点各个击破，就能慢慢地应用自如了。
