Chapter 1状语从句
（条件、时间状语从句）
英语中的状语从句有九大类。这九类从句是：时间、地点、原因、目的、结果、条件、让步、比较、方式以下是常见的七种：
条件状语从句：表示主句动作发生的条件，通常又if（如果）,unless（除非）, as long as(只要) 等引导，表示假如
从句的动作发生就会有主句的动作发生。从句在前，需要逗号，主句
在前则不需要。
1．条件状语从句与主句的时态搭配----------主将从现
e.g. If it rains tomorrow, I will take my umbrella.
(从现) （主将）
You will fail unless you study hard. = You will fail if you don’t study hard.
（主将）(从现)
1. He ___________ (leave) if it __________(be) fine tomorrow.
2. If it __________(rain), we’ll visit the museum.
3. You __________ (be) late unless you ___________(leave) immediately.
4. What _________ you ________(do) if you ___________(have) much money?
5. __________ you _________ (help) others if they ____________(be) in trouble?
2. 当主句表示常规性\真理性的结果时,主句与从句都使用一般现在时.
e.g. If you cool the water, it turn s into ice.
Water turns into steam if you boil it.
1.If you _________ (take) a fish out of water, it _________(die).
2. A person___________(die) if he __________(be) out of air.
3.如果你把金属放进水中,金属不会漂浮起来.

4.如果你把玻璃杯摔下来,它会碎.
The glass ___________ if you __________ it.
5.如果不给植物浇水,他们会死.
If you __________ give plants __________, they __________.
3. 当主句是祈使句或含有情态动词时, 从句使用一般现在时.
e.g. You can do better if you work harder.
Don’t smoke here unless you are permitted.
1.__________(tidy) your room if you __________(want) to invite your friends home.
2.You ___________ (must work) harder if you ___________(want) to pass the exam.

the others.
4.Please ___________(put up) your hand if you ____________(not understand).
5.You ___________ (can ) switch on the air conditioner if you ___________(feel) hot.
4. Unless 与If 的联系与区别, Unless = If``````` not, 通常我们还可以翻译为“如果不，如果没有”，但是Unless 不能引导否定的条件状语从句，If 没有此种限制。
e.g. You will fail unless you study harder.= You will fail if you don’t study hard.
将下列含unless的句子改为if条件句
1.You will have a cold unless you put on the coat.
___________________________________________________________________________ 2.You will get wet in the rain unless you take an umbrella.
___________________________________________________________________________ 3.I shall leave this restaurant unless the waiter comes soon.
___________________________________________________________________________ 4.You can’t speak English well unless you practice it every day.
___________________________________________________________________________ 5.We shan’t go on the picnic unless the weather is fine.
___________________________________________________________________________
5. 并列句与条件句的转换:
e.g. Hurry up, or you’ll be late.= Unles s you hurry up, you will be late.
Study hard, and you will pass the exam.=If you study hard, you will pass the exam.
将下列句子改写成条件句:
1.Put on your glasses, and you will read better.
__________________________________________________________________________ 2.Be quick, or you will miss the early bus.
__________________________________________________________________________ 3.Don’t break that vase, or you will have to pay for it.
__________________________________________________________________________ 4.Think hard, you will find a good way.
__________________________________________________________________________ 5.Go to bed early, or you won’t get up early.
__________________________________________________________________________ 6. if的两面性if引导条件状语从句时意为“如果”，如果引导宾语从句则意为“是否”。
1) We will go out if it is fine tomorrow.(如果,状从)
2) I don’t know if the train has arrived. (是否,宾从)

as引导的时间状语从句 as是高中英语中非常重要的一个词汇，它的用法非常的复杂，且在每年的高中英语考试中占有非常重要的位置。其中as引导的时间状语从句尤为复杂，本文以as在引导时间状语从句时的三种不同意义为线索，细致讲述as引导时间状语从句这一语法知识点。 as引导时间状语从句表示"当....时候" as在表示"当....时候"的意义时，与"while"引导时间状语从句有一个共同点，就是此时从句的谓语动词一定要用表示延续性的动词。 例句1：She stayed up late writing her paper while our kids and I were sleeping. 当我和孩子们在睡觉的时候，她在熬夜写论文。 注释：这个句中while引导的时间状语从句的谓语动词是表示延续性的"were sleeping"。例句2：They all finished their homework, as I was playing with my dog. 当我在和我的小狗玩耍的时候，他们都完成了家庭作业。 注释：从句中的谓语动词"was playing"是表示延续性的动词。 as引导时间状语从句表示"一边...一边..." 当as表示"一边...一边..."引导时间状语从句时，主句和从句的动作同时发生，此时从句的谓语动词没有要求。 例句1：As she explained her misfortunes, she wiped tears off her cheeks. 她一边讲述着自己的不幸遭遇，一边擦去脸上的泪水。 例句2：She cried as she walked alone on the dark road. 她一边独自走在黑暗的小路上，一边哭泣。
如何区分定语从句、宾语从句和状语从句？（附习题）| 虫虫讲英语 2018-12-02 14:52 「虫虫讲英语」老少咸宜的英语学习号——有时候，语法换一种方式讲，就听懂了。 如何区分定语从句、宾语从句和状语从句，是学生最常问我的问题之一。今天，我们通过青铜、白银、黄金、王者四级难度的例句，一起研究下怎样一眼辨别英语3大从句。 01 概念 3大从句的区别均在于前面两个字：定语、宾语和状语： 知道了这几个概念，这三种从句就很好理解了： >> 定语从句：作定语的从句，做adj.修饰先行词；
在这里，dog “狗子” 是先行词，即“走在定语从句前面的名词”；定语从句 that shits a lot 其中的 that，指 代了前面的 dog，告诉我们这是一条怎样的狗子：拉很多的狗子。 >> 宾语从句：作宾语的从句，放在动词或介词后面； 第一句，宾语从句为普通的陈述句，放在 think 这个动作后面，由连接词 that 引导。 第二句，宾语从句已经改成陈述句语序，原来人讲的话则是一般疑问句Do you let it go “你丫放不放手” ？该从句放在 depend on 的介词 on 后面，一般疑问句由 whether/ if 引导。 >> 状语从句：作状语的从句，给主句增加信息量。 状语从句，是3大从句中比较好记的一种：有个完整的主句，从句是提供更多信息的，比如上述例句告诉我们他为什么养狗。只要熟悉九大状语从句的引导词（← 戳可查看），几乎一眼就能辨别出状语从句。 02 当堂练习 现在，我们一起看几个句子找找感觉。请判断下列句子是定语从句，宾语从句还是状语从句？ >> 青铜 1. If it is fine tomorrow, I will visit you. 2. I helped an old man who lost his way.
状语从句翻译 I. fronting 1)The moment I saw him I knew there was no hope. 2)While he was in hospital, Mr. Gilbert asked his doctor to tell him whether his operation had been successful, but the doctor refused to do so . 4) As soon as he saw us, the snake charmer picked up a long pipe which was covered with coins and opened one of the baskets. 5)My old friend , Harrison, had lived in the the Mediterranean for many years before he returned to Englland. 6)In the end , it was more than he could bear. He had hardly had time to settle down when he sold the house and left the country . 7)When the doctor answered the phone, Mr Gilbert said he was inquiring about a certain patient, a Mr John Gibert. . 8)Mrs Anne Sterling did not think of the risk she was taking when she ran through a forest after two men. 1) The crops failed because the season was dry。 2)You took me because I was useful. There is no question of gratitude between us. 3)Pure iron is not used in industry because it is too soft。 4）As a great many people will be visiting the country, the government will be building new hotels, an immense stadium, and a new Olympic-standard swimming pool. 5）Now that you are a college student, you should learn to be independent of your parents' help. 1)Byrd now knew that he would be albe to reach the South Pole which was 300 miles away, for there were no mountains in sight. 2)Almost at once he began to complain about the weather, for even though it was still summer, it rained continually and itd was often bitterly cold. 3) People at that time condemned sociability itself, on the grounds that it might interfere with work and study
as作从属连词用时,可以引导五种状语从句。现归纳如下： 1. as表示“当……的时候”,引导时间状语从句,多强调主句和从句中的动作或状态同时发生,从句可放在主句前,也可放在主句后。例如： As I waited at the stop, I heard a big noise. 当我在车站等车的时候,我听到一个很大的声响。 She rose up as he entered. 当他进来时,她站了起来。 2. as表示“因为”、“由于”,引导原因状语从句,其语气不如because强,通常为附加说明的理由,且是已知晓的原因,主句与从句没有逻辑上的因果关系。例如： As she was not well, I went there alone. 因为她身体不好,所以我独自到那里去了。 As he is a tailor, he knows what to do with this material. 由于他是个裁缝,他知道怎样利用这块布料。 3. as表示“虽然……但是……”,引导让步状语从句,从句通常用倒装语序,把从句的表语、状语或动词原形放在as前面,可以用though替代。例如： Child as he is, he knows a lot. 虽然他是个孩子,但他知道的东西很多。 Hard as it was raining, they went on working in the field. 虽然天下大雨,但他们继续在田地里干活。 4. as表示“按照”、“依照”、“像”,引导方式状语从句,从句置于主句之后。例如： You should do as the teacher tells you.你应当依照老师所说的去做。 The absence of air also explains why the stars do not seem to twinkle in space as they do from the earth. 空气的不存在,也说明了为什么在空中星星看来并不闪烁,而不像从地球上看的那样。 5. as表示“像……一样”,引导比较状语从句,对主句和从句的动作或状态加以比较,说明它们之间有相似之处,在从句中常省略与主句相同的部分。例如： He doesn't work as hard as I (do). 他不像我工作那样努力。 I hope the necklace was as good as the one you lent me.我希望我挂项链同你借给我的一样好。
学法导航 定语从句与其易混淆句型的辨析 安丘一中高二英语组李建文 众所周知，定语从句是高中英语学习中的一个语法重点，老师、同学们都对此予以重点关注。由此造成了这样一种现象：做题时，一遇到从句就往定语从句上想，尤其容易把一些形式上与定语从句相似的句型（主要是同位语从句、强调句、地点和时间状语从句）也当作定语从句来理解，结果产生错误。因此，从某个方面来说，解答定语从句题的关键是弄清它和易混淆句型之间的区别。 一、定语从句与同位语从句 定语从句和同位语从句都置于被修饰的名词或代词之后，形式上非常相似，尤其是由that引导时，最难区分。实际上，两者的根本区别在于句法功能不同，与先行词的关系不同。 1. 句法功能不同 定语从句相当于一个形容词，用来修饰、描述或限制其前面的名词、代词（称为先行词）或整个句子；同位语从句则相当于一个名词，是先行词所述内容的展开，即说明先行词的具体内容。 定语从句的引导词that在从句中一定充当句子成分；而同位语从句中的引导词that（被称为连接代词）在从句中只起连接作用，不充当任何句子成分。 定语从句的引导词在从句中作宾语或状语时，可以省略或被其他词代替；而同位语从句的引导词则一般不能省略，也不能被代替。 例1The news （that / which） we picked up from his informal conversation is true.我们从他的闲谈中听到的那个消息是真实的。 例2The news that Mr Li will teach us English next semester is true. 李先生下学期将教我们英语这个消息是真实的。 点评：例1的中that从句是定语从句，其作用相当于一个形容词，用来限定the news，that在从句中作宾语，可省略。例2中的that从句是同位语从句，其作用相当于一个名词，本身就是the news的内容，that不能省略。 2. 与先行词关系不同 定语从句所修饰、限定的先行词可以是名词或代词，当that省略时，定语从句本身是一个不完整的句子。而同位语从句通常与一些本身有具体内容可展开的名词连用，对这些名词进行补充说明或解释。常见的此类名词有：answer， belief， doubt， decision，explanation， fact， hope， idea， information， message， news， order， possibility，problem， promise， question， reason， story， suggestion， thought， truth等。同位语从句本身是一个完整的句子，常用that连接而不是用which 引导，that本身不充当句子成分，表示疑问意义的名词（如doubt， question等）后也可用whether， who， what 等疑问词引导。 例3The fact (that / which) she told me yesterday is very important.她昨天告诉我的事实非常重要。 例4The fact that she hasn’t known the result of the examination is clear.她还不知道考试成绩这个事实是显而易见的。 点评：例3中that / which引导的是定语从句，修饰fact，用以限定说明是哪个fact，
并列句与状语从句 语法填空 1．(2016·高考全国卷Ⅲ语法填空)Over time，________the population grew, people began cutting food into small pieces so it would cook more quickly. 2．(2016·高考全国卷Ⅱ语法填空)So，get an early start and try to be as productive ________possible before lunch. 3．(高考全国卷Ⅰ语法填空)But the river wasn't changed in a few days ________ even a few months. 4．(高考全国卷Ⅱ语法填空)There were many people waiting at the bus stop，________some of them looked very anxious and disappointed. 一、掌握五种常考的并列连词 1．表示转折关系的并列连词，包括but，while(而)等，其中，while连接并列句时，两分句之间是对比关系。 2．表示平行或对等关系的并列连词，常见的有and，not only ...but (also)等。 3．表示选择关系的并列连词，常见的有or，either ...or等。 4．表示因果关系的并列连词，常见的有for，so等。 5．特殊并列连词 when可用于并列连词，意为“这时，那时”，相当于and at this/that time。常用于下列句式： (1)be about to do sth. when ...“正要做某事，这时突然……” (2)be on the point of doing sth. when ...“正要做某事，这时突然……” (3)be doing sth. when ...“正在做某事，这时突然……” (4)had done sth. when ...“刚做了某事，这时突然……” He was about to go to school when a strong wind began to blow. 他正要去上学，这时突然刮起了大风。 错误! Register in Renren，and you will be able to get in touch with the friends whom you haven't seen for a long time. 在人人网注册后你就能与你很久没见面的朋友取得联系了。 二、熟记状语从句的常考连词 1．引导时间状语从句的常考连词 (1)when表示“当……的时候”； (2)while表示“当……的时候”(while所引导的时间状语从句中谓语动词必须是持续性的，不能是短暂性的)； (3)as表示“当……的时候；随着”； (4)before表示“在…之前”； (5)after表示“在……之后”； (6)until/till表示“直到……”； (7)since表示“自从……以来”。 We had sailed four days and four nights before we saw land. 我们航行了四天四夜才看到陆地。 2．引导条件状语从句的常考连词 (1)if意为“如果”； (2)unless意为“如果不；除非”； (3)as/so long as意为“如果；只要”； (4)in case用作连词引导条件状语从句时，意为“如果；万一”。 If you don't study hard，you'll fail the exam. 如果你不努力学习，考试就会不及格。 3．引导让步状语从句的常考连词 (1)although与though虽然拼写不同，但意思相同，都表示“虽然”，不能与but连用，可与yet，still连用； (2)as引导让步状语从句时，需用倒装句式，though引导的让步状语从句，既可倒装也可不倒装，although / while 引导的让步状语从句不可倒装； (3)whether ...or ...的意思是“无论……还是……；不管……还是……”； (4)even though和even if意思相同，均表示“即使”； (5)有时还可用那些以-ever结尾的词语来引导，如whatever，whoever，however，whenever，wherever等，它们
where引导的定语从句和地点状语从句的区别是什么？ 最简单的办法是看where是否有指代先行词 应到定语从句还是状语从句的区别主要可以从以下三点来看： 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 River meet. 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. （＝Bamboo grows best 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。

初中英语状语从句 【考点直击】 1. 时间状语从句 2. 条件状语从句 3. 原因状语从句 4. 结果状语从句 5. 比较状语从句 6. 目的状语从句 7. 让步状语从句 8. 地点状语从句 【名师点睛】 用来修饰主句中的动词，副词和形容词的从句叫状语从句。根据其含义状语从句可分为时间状语从句，地点状语从句，条件状语从句，原因状语从句，结果状语从句，比较状语从句，目的状语从句，让步状语从句。 1. 时间状语从句 (1)时间状语从句常用when, as, while, before, after, since, till, until, as soon as等连词来引导。例如： It was raining hard when got to school yesterday. While he was doing his homework, the telephone rang. As he walked along the lake, he sang happily. He had learned a little Chinese before he came to China. After he finished middle school, he went to work in a factory. (2)在时间状语从句里，通常不用将来时态，用现在时态表示将来的动作或状态。例如： I’ll ring you up as soon as I get to New York. I will tell him everything when he comes back. He won’t believe it until he sees it with his own eyes. (3)在带有till或until引导的时间状语从句的主从复合句里，如果主句用肯定式，其含义是“一直到……时”，谓语动词只能用延续性动词。如果主句用否定式，其含义是“直到……才……”, “在……以前不……”, 谓语动词可用瞬间动词。例如：The young man read till the light went out. Let’s wait until the rain stops. We won’t start until Bob comes. Don’t get off until the bus stops. 2. 条件状语从句 (1)条件状语从句通常由if, unless引导。例如： What shall we do if it snows tomorrow? Don’t lea ve the building unless I tell you to. (2)在条件状语从句里，谓语动词通常用现在时态表示将来的动作或状态。例如： I’ll help you with your English if am free tomorrow. He won’t be late unless he is ill. (3)“祈使句+ and (or)+ 陈述句”在意思上相当于一个带有条件状语从句的复合句。例如： Hurry up, or you’ll be late. =If you don’t hurry up, you’ll be late. Study hard and you will pass the exam. =If you study hard, you will pass the exam. 3. 原因状语从句 (1)原因状语从句通常由because, since, as引导。例如： He didn’t come to school because he was ill. As it is raining, we shall not go the zoo. Since you can’t answer the question, I’ll ask someone else. (2)because表示直接原因，语气最强。Because引导的原因状语从句多放在主句之后。回答由why提出的问题，只能用because。
定语从句与其易混淆句型的辨析 众所周知，定语从句是高中英语学习中的一个语法重点，老师、同学们都对此予以重点关注。由此造成了这样一种现象：做题时，一遇到从句就往定语从句上想，尤其容易把一些形式上与定语从句相似的句型（主要是同位语从句、强调句、地点和时间状语从句）也当作定语从句来理解，结果产生错误。因此，从某个方面来说，解答定语从句题的关键是弄清它和易混淆句型之间的区别。 一、定语从句与同位语从句 定语从句和同位语从句都置于被修饰的名词或代词之后，形式上非常相似，尤其是由that引导时，最难区分。实际上，两者的根本区别在于句法功能不同，与先行词的关系不同。 1. 句法功能不同 定语从句相当于一个形容词，用来修饰、描述或限制其前面的名词、代词（称为先行词）或整个句子；同位语从句则相当于一个名词，是先行词所述内容的展开，即说明先行词的具体内容。 定语从句的引导词that在从句中一定充当句子成分；而同位语从句中的引导词that（被称为连接代词）在从句中只起连接作用，不充当任何句子成分。 定语从句的引导词在从句中作宾语或状语时，可以省略或被其他词代替；而同位语从句的引导词则一般不能省略，也不能被代替。 例1The news （that / which）we picked up from his informal conversation is true.我们从他的闲谈中听到的那个消息是真实的。 例2The news that Mr Li will teach us English next semester is true. 李先生下学期将教我们英语这个消息是真实的。 点评：例1的中that从句是定语从句，其作用相当于一个形容词，用来限定the news，that在从句中作宾语，可省略。例2中的that从句是同位语从句，其作用相当于一个名词，本身就是the news的内容，that不能省略。 2. 与先行词关系不同 定语从句所修饰、限定的先行词可以是名词或代词，当that省略时，定语从句本身是一个不完整的句子。而同位语从句通常与一些本身有具体内容可展开的名词连用，对这些名词进行补充说明或解释。常见的此类名词有：answer，belief，doubt，decision，explanation，fact，hope，idea，information，message，news，order，possibility，problem，promise，question，reason，story，suggestion，thought，truth等。同位语从句本身是一个完整的句子，常用that连接而不是用which 引导，that本身不充当句子成分，表示疑问意义的名词（如doubt，question等）后也可用whether，who，what等疑问词引导。 例3The fact (that / which) she told me yesterday is very important.她昨天告诉我的事实非常重要。 例4The fact that she hasn’t known the result of the examination is clear.她还不知道考试成绩这个事实是显而易见的。

1 as引导的从句崔长平河南省遂平中学（463100） 在英语中，as作为一个常见的从句引导词，其用法和意义十分活跃而丰富，若不加以区分，很容易造成混淆。现将其主要用法归纳如下： 1）引导时间状语从句①在as引导的时间状语从句中，谓语动词既可以是延续性的也可以是非延续性的；有时从句的谓语动词也可用进行时形式。②as引导的时间状语从句常可用来强调主、从句中的动作同时发生或伴随发生，常译作“随着……”，“一边……一边……”，“一……就……”等。③在省略句中，as之后经常放置一个名词或名词词组。 I heard the murmur of their voices as I crossed the hall. A look of surprise came into Alison’s eyes as she read the message. Scott became nervous as he saw her face. Just as he was speaking there was a loud explosion. He smiled as he passed. As she sang，the tears ran down her cheeks. We get wiser as we get older. As a young man，he was a store keeper and later a postmaster. 2）引导让步状语从句象although，though，while一样，as也可以用来引导一个让步状语从句，意为“尽管，虽然”， as引导的这种让步状语从句语气比较强，语体正规，经常用于书面语言，但as引导的让步状语从句须倒装。其倒装要求如下：①表语＋as＋主语＋系动词（表语经常是由形容词、分词、或名词充当；名词用作表语时，其前不能加用冠词。） Young as he is，he is equal to the task. Crowded as the restaurant was，they tried to find a table. Child as he was，he knew what was the right thing to do. ②状语﹢as﹢主语﹢谓语动词（这一结构中的谓语动词一般是行为动词，既可以是及物动词（带宾语）也可以是不及物动词。） Hard as he studied，he did not get good marks in the exam. Early as we got there，our teacher was there before us. Much as I admire him as a writer I don’t like him as a man. ③动词＋as ＋主语＋……（在这一结构中，主语后面一般加上情态动词may，might，will，would，can，could等，句首的动词应该保持原形。如果从句中没有情态动词，那么，应在从句的主语之后（根据时态和数的要求）加上助动词do、does或did。在这一结构中，放在句首的动词如果是及物动词，那么，这个动词连同它的宾语一起放到as之前。） Search as they would，they could find nothing in the house. Try as he may，he will fail in the examination. Die as he did，his inspiration lived on. Lose money as I did，I got a lot of experience. 3）引导原因状语从句 as引导原因状语从句时，语气不及because强烈，它接近于since，now that，一般译作“既然，由于”之类的意义，只是“附带说明的理由”，表达一种说话人和听话人“共知的原因”。as引导的原因状语从句一般置于主句之前。 As all the seats were full he stood up. As Davidson had a passion for walking，we started off on foot. As you are sorry，I’ll forgive you. It is very difficult for us to know what to do as we are not his parents.
一、从句是如何出题的 1. 时态 2. 考连接词 3. 考语言顺序 二、学好从句的两个基本条件 1. 时态 2. 从句的三个必须:①必须是句子；②必须有连接词；③必须是陈述句 三、状语从句、宾语从句、定语从句重点 1.如何判断何种从句 2. 从句的时态 3. 从句的连接词与扩展 4. 经典单选、从句与选词、长句子分析 四、如何判断三种从句 1. 状语从句无先行词 2. 宾语(表语)从句无先行词有动词或词组 3. 定语从句先行词多为名词或代词 一、When引导的定语从句与时间状语从句的区分 1. when的译法不同。在时间状语中，when 翻译成“当……的时候”I want to be a teacher when I grow up. 当我长大的时候，我要做一名老师。在定语从句中，when不翻译。I won't forget the day when he says he loves me. 我不会忘记他说爱我的那一天。 2. 在时间状语中，when从句前面或后面是句子；定语从句中，when从句不能位于句首，且通常when前为表示时间的名词day、year等。 3. when在从句的作用不同。在时间状语从句中，when是连词，只起连接主句和从句的作用，不做从句的任何成分。不过when引导的时间状语从句修饰主句的谓语，做主句的时间状语。 在定语从句中，when是关系副词，在从句中代替先行词做从句的时间状语，修饰从句的谓语。 例1 I will always remember the days when I lived with my grandparents in the country. 例2 I always remember the days in the country when I see the photo of my grandparents. 点评：例1意为“我会永远记得跟我祖父母一起住在乡下的那些日子”，其中when 引导的是一个定语从句, 修饰the days, when在从句中作时间状语。例2意为“当我看到祖父母的照片时，总是会想起在
