英语常用句型It be time +(that)从句讲解
在英语里，“It be time +（that）从句”是一个较为常用的句型，它表示“该做……的时候了”的意思。该句型属于主从复合句的一种；其主句部分为“It be time”，从句部分的连词that可以省略。以下从三个方面简要谈谈这一句型。
一、time前面的修饰语
句型“It be time +（that）从句”通常暗示“有点迟了”，为了强调这一含义，可以在time的前面加形容词high。例如：
It's high time we started.
It is high time that more women ran the arts.
为了使语气得到进一步的加强，还可以在high的前面加certainly， more than等副词或词组：
It is certainly high time that we ordered dinner.
形容词full也可以加在time的前面，用来加强语气。例如：
It's full time you had a nice day.
It is full time that boy went to herding.
time前面还可以加about，这时句型所表达的意思是“早该……”。例如：
It's about time we started.
It's about time I settled down.
上面两例中的about可以用getting来代替，句意不变；这可以视为句型“It be time +（that）从句”的一种变体。
二、从句中的动词形式
在“(that)从句”中，动词形式通常是一般过去时。这是一种奇特而有趣的语言现象，即用假设的过去时来代替实际的将来时。从英语史的角度来看，从句中的动词形式用过去时原是属虚拟语气；但从语言发展的观点来看，目前这种动词形式视为陈述语气比较合适。
著名语言学家夸克（R. Quirk）教授等人在1985年出版的《英语语法大全》一书中认为，“(that)从句”的动词形式一定要用“假设的过去时”。他们举了一例：It's time I was in bed.其实，动词形式除常用过去时外，也可以用其他时态和语态（用何种形式应视情况而定）。正如著名语言学家周海中教授在1988年发表的《探讨“It be time （that）…”句型》一文中所言：在现代英语里，“(that)从句”中的动词形式一般用
过去时，这是基本规则；有时也可以用其他的动词形式，但应视为特殊用法。他在其文中列举了大量实例，用于论证和说明。
1．用were型虚拟语气。例如：
It's high time I were hence. (W. Shakespeare)
It's time I were gone. (A. Tennyson)
由于英语的发展，虚拟语气与陈述语气之间的区别正在逐渐消失。基于这种情况，虚拟语气的were也正在逐渐地代替陈述语气的was。
2．用be型虚拟语气。例如：
You reckon I be found anywhere with him, time he start belle ring. (W. Faulkner)
It is time that more of the research dollars now devoted to cure be diverted to finding new and more humane ways of curing that will make a cancer patient's remaining years happier, more comfortable, and more productive. (Science, 1984, Vol. 5, No.7)
动词形式用be型虚拟语气是古英语的用法。目前，这一用法在英国英语中已“日薄西山”，而在美国英语中却有“东山再起”之势，但主要见于正式文体。
3．借助情态动词should
It's time this heart should be unmoved. (G. Byron)
It may be time that I should meet with some misfortune; but I hope it is not this. (C. Dickens)
上面用法主要见于文学作品，尤其是英国人写的。
4．用过去进行时。例如：
It's time we were leaving. (H. Maclnnes)
It's time we were getting home. (E. O'Neil)
上面用法通常是一些表示位置转移的动作动词。
5．用一般现在时。例如：
It is high time that the U. S. realizes it cannot continue to hide its head in the sand, for the sand has started to blow. (Newsweek, Oct. 15, 1979)
“It is time that the burden of Reaganomics is shared by those in the upper-income groups,” 0'Neill declared. (Time, Jun. 20, 1983)
上面用法主要见于美国英语，尤其在新闻文体里。这是一种值得关注的语言现象。
6．用完成时。例如：
It's time that reduction in force has finally hit the federal government also. (U. S. News and World Report, Mar. 15, 1982)
Fooleries! Pshaw! It's time you'd done with fooleries. (G. Eliot)
上面用法也是一种值得关注的语言现象。
三、句型中的省略现象
在口语中，可以把句型“It be time +（that）从句”中的“It be”省略。例如：High time we left. （J. Linsay)
Time we were going. (M. Hammonds)
在一定的上下语境中，也可以把句型中的“(that)从句”省略。例如：
This program goes in that direction, and I believe it's time. （T. Wicker)
在特定的语境里，甚至还可以把句型中的“It be”和“(that)从句”都省掉，意义仍然是显豁的；不过，这时time前面要用high来修饰，其后面常跟副词too，该词只是用来加强语气，并无具体意义。例如：
He's gone back to work.—— High time, too! (Longman Dictionary of English Idioms) 顺带一提，句型“It be the +序数词+ time +（that）从句”与句型“It be time +（that）从句”在结构上有点相似，但它们在句意上是完全不同的。前者也是主从复合句，当其主句的be用一般现在时，从句的动词形式通常为现在完成时，it可以用this 来代替；当其主句的be用一般过去时，从句的动词形式通常为过去完成时，it可以用that 来代替。例如：
It/This is the first time (that) I have seen him.
It/That was the third time (that) I had been there.

初中英语语法——三大从句汇总(重点笔记)知识讲解
初中英语语法——三大从句汇总 在英语中，主要有三大从句，即名词性从句（包括主语从句，宾语从句，表语从句，同位语从句）、形容词性从句（即定语从句）、副词性从句（即 状语从句,包括时间、条件、结果、目的、原因、让步、地点、方式等）。以 下是一些基本的从句的语法知识点 A、定语从句专项讲解与训练 一、定语从句概念 定语从句（attributive clause），顾名思义，就是一个句子作定语从属于主句。定语一般是由形容词充当，所以定语从句又称作形容词从句。另外，定语从句是由关系代词或关系副词引导的，故又称作关系从句。 定语从句一般放在它所修饰的名词或代词之后，这种名词或代词被称作先行词。请看示例： The woman who lives next door is a teacher. 先行词定语从句 在所有的从句中，算定语从句最难掌握，因为汉语里没有定语从句，汉语里只有定语，而且总是放在名词之前来修饰名词。 二、关系代词引导的定语从句 关系代词代替前面的先行词，并且在定语从句中充当句子成分，可以作主语、宾语、定语等。常见的关系代词有：who, that, which。它们的主格、宾格和所有格如下表所示： 先行词主格宾格所有格 人 who whom whose 物 which which whose of which 人、物 that that — （一）关系代词who, whom和 whose的用法 who代替人，是主格，在定语从句中作主语。例如： An architect is a person who designs buildings. 建筑师是设计房屋的人。
I will never forget the teacher who taught us chemistry in the first year of my senior middle school.我将永远不会忘记在高一时教我们化学的那位老师。 Anyone who wants to apply for this job must send us the resume by email first. 想应聘这个职位的任何人都必须先通过电子邮件向我们发送简历。whom代替人，是宾格，在定语从句作宾语，在非正式英语常可省略。例如：Do you know the gentleman whom we met in the school library yesterday? 昨天我们在学校图书馆里遇到的那位先生你认识吗？ This is the student whom my father taught ten years ago.这是我爸爸十年前教的学生。 The girl who I saw is called Mary. 我见到的那个女孩名叫玛丽。（在非正式英语中，主格who代替了宾格whom，亦可省略） whose一般代替人，有时亦可代替物，是所有格，在定语从句作定语。例如：The girl student whose father is a senior engineer used to study abroad. 其父是一位高级工程师的那个女学生过去在国外留学。 Do you know the name of the hotel whose window we can see here? 我们这儿能看到窗户的那个宾馆叫什么名字，你知道吗？（关系代词whose指代先行词hotel，正式用法应该用of which。whose window=the window of which，意思是：the window of the hotel。） （二）关系代词which的用法 which代替物，在定语从句作主语或宾语，作宾语时还可省略。例如： I do not like stories which have unhappy endings. 我不喜欢有不幸结局的小说。（which可以换成that） Tom works for a factory which makes watches. 汤姆在一个制表厂工作。（which可以换成that） （三）关系代词that的用法 that既可指人又可指物，在当代英语中大多指物，在定语从句作主语或宾语，作宾语时还可省略。例如： Is she the girl that sells newspapers? 她是卖报纸的那个女孩吗？（that可以换成who） Where is the ice-cream that was in the fridge?

英语语法从句讲解
从句 从句按其在主句中的句法功能可分为三类: 即名词性从句、形容词性从句(即定语从句)和副词性从句(即状语从句)。 引导从句的词称作关联句. 一、名词性从句 引导这些名词性从句的关联词包括: 从属连词that, if, whether; 连接代词 who,whoever,whom,whomever,which,whichever,what,whatever,wh ose; 连接副词where, when, why, how。 其中, 从属连词只起连接作用, 在从句中不充当任何句法成分, 而连接代词和连接副词既起连接作用, 在从句中又充当一定的成分. That Owen should have married his cousin is not at all surprising. The fact is that he didn't go to the dinner party. I don't know if he will attend the meeting. Have you heard the news that Mary is going to marry Tom? 你听说玛丽要和汤姆结婚的消息了吗?(that引导同位语从句) [提示]
1. 在含有主语从句的复合句中, 为保持句子平衡, 常用it作形式主语,而将真正的主语从句置于句末. It's well-known that water is indispensable to life.(形式主语) 2. 为保持句子平衡, that引导的宾语从句也常用it代替, 而将真正的宾语从句置于主句句末。这常常出现在主句有形容词或分词作宾语补足语的情况下。 He made it quite clear that he preferred to live here. 3. 从属连词whether和if都作“是否…”解, 但if不可引导主语从句和表语 从句。whether可与or(not)连用, 而if不可以。 I don't know whether (if) she is at home. Whether she comes or not makes no difference. 4. that和what引导名词性从句的区别: that在从句中不充当成分,而what在从句中充当一定的成分, 如主语、表语、宾语等。that可省略, what则不可省。 He always means what he says. She suggested (that) he do it at once. 5. 同位语从句大多由从属连词that引导, 常跟在下列名词后面, 如fact, idea, opinion, news, hope, belief等, that不可省。同位语从句一般用来解释说明这些名词的具体含义和内容。 We are familiar with the idea that all matter consists of atoms. The news that we are invited to the conference is very encouraging.

英语五种基本句型列式如下： 一：ＳＶ（主＋谓） 二：ＳＶＰ（主＋系＋表） 三：ＳＶＯ（主＋谓＋宾） 四：ＳＶｏＯ（主＋谓＋间宾＋直宾） 五：ＳＶＯＣ（主＋谓＋宾＋宾补） 主语：可以作主语的成分有名词（如boy），主格代词（如you），动词不定式，动名词等。主语一般在句首。注意名词单数形式常和冠词不分家！ 谓语：谓语由动词构成，是英语时态、语态变化的主角，一般在主语之后。不及物动词（vi.）没有宾语，形成主谓结构，如：We come.
此句型的句子有一个共同特点，即句子的谓语动词都能表达完整的意思。这类动词叫做不及物动词，后面可以跟副词、介词短语、状语从句等。 Ｓ│ Ｖ（不及物动词） 1. The sun │was shining.太阳在照耀着。 2. The moon │rose. 月亮升起了。 3. The universe │remains. 宇宙长存。 4. We all │breathe, eat, and drink. 我们大家都呼吸、吃和喝。 5. Who │cares? 管它呢？ 6. What he said │does not matter. 他所讲的没有什么关系。 7. They │talked for half an hour. 他们谈了半个小时。 8. The pen │writes smoothly 这支笔书写流利。 此句型的句子有一个共同的特点：句子谓语动词都不能表达一个完整的意思，必须加上一个表明主语身份或状态的表语构成复合谓语，才能表达完整的意思。这类动词叫做连系动词。系动词分两类：be, look, keep, seem等属一类，表示情况；get, grow, become, turn等属另一类，

英语名词性从句练习全集及解析 一、初中英语名词性从句 1．________ manners are very important in every country is known to all，but the trouble is that different countries have different ideas about ________ good manners are. A. That; what B. That; that C. What; that D. What; what 【答案】 A 【解析】【分析】句意：众说周知，礼貌在每一个国家中都是非常重要的，但是麻烦是，不同的国家对于什么是良好的礼貌有着不同的认识。逗号前有两个谓语动词，一个是are，一个是is known，故是两句话，需填连词连接这两句话，根据句意可知，前面是主语从句，故填that，此处的that，只起连接作用不作任何成分。about是介词，其后是个句子故应填连词把这两句话连接起来，所缺词作are的表语，故填what。因此选A。 【点评】考查名词性从句，本题涉及that引导的主语从句和what引导的宾语从句。 2．Some people believe _______ has happened before or is happening now will repeat itself in the future. A. whatever B. whenever C. wherever D. no matter what 【答案】 A 【解析】【分析】句意：一些人认为之前发生的或现在正在发生的任何事情在将来都会重复发生。Whatever has happened before or is happening now是一个主语从句，whatever既引导起这个主语从句，也在句中做主语。BC项都属于副词的性质，都不能做主语，通常只能做状语；no matter what只能用来引导状语从句，故选A。 【点评】考查名词性从句，本题涉及"特殊疑问词+ever"引导的主语从句。 3． is even more important is the earth cooled down, water began to appear on its surface. A. When; that; when B. What; whether; as C. What; that; as D. lt; whether; as 【答案】 C 【解析】【分析】这题考查从句的用法，第一空填what引导主语从句，在主语从句中what做主语，第二空填that引导表语从句，在表语从句中，as是引导时间状语从句，句意是：甚至更重要的是：随着地球的冷却，水开始出现在表面。选C。 4．Has it been announced ______? A. when are the planes to take off B. that are the planes to take off C. where are the planes to take off D. when the planes are to take off 【答案】 D 【解析】【分析】句意: 飞机什么时候起飞已经宣布了吗？此处是when引导的主语从句，且要用陈述句语序，故选D。

高一英语定语从句讲解精华版
定语从句 一、基本概念： 定语： 定语从句： Do you know the man who spoke at the meeting just now That is the house where he lived ten years ago. 引导词：关系词 关系代词有：that, who, whom, whose, which; 在从句中充当： 关系副词有：when, where, why. 在从句充当： 先行词： 定语从句中引关系词的作用： 二、关系词的用法： （一）关系代词的用法： 1． He is the man lives next door. The train has just left is for Shenzhen. 2． The man ________ we have just seen is a famous writer. Where is the book ___________I bought last week （二）关系副词的用法： 1． I still remember the time ________I first became a college student. Do you know the date __________Lincoln was born
(三) 使用关系副词应注意下列几点： 1．这三个关系副词在意义上都相当于一定的介词+which结构： when = on (in, at, during…) + which; where = in (at, on…) + which; why = for which. 如： I was in Beijing on the day when (=on which) he arrived. The office where (=in which) he works is on the third floor. This is the chief reason why (=for which) we did it. 2．当先行词是表时间的time, day等和表地点的place, house等时，一定要注意分析从句的结构，如果缺少主语或宾语时，关系词应该用which或that, 缺少时间状语或地点状语时，才能用when或where，试比较： I’ll never forget the day _________ my hometown was liberated. I’ll never forget the days____________we spent together last summer. His father works in a factory____________radio parts are made. His father works in a factory______________makes radio parts. 三．限制性定语从句与非限制性定语从句 1．限制性定语从句 This is the telegram which he refers to.

【初中英语语法——三大从句之表语从句】 【表语从句】 表语从句就是用一个句子作为表语。说明主语是什么或者怎么样，由名词、形容词或相当于名词或形容词的词或短语充当，和连系动词一起构成谓语。 表语从句只能置于主句之后，而主句的动词只能是联系动词。 名词性从句在be等系动词后作表语时被称为表语从句，例如： T he problem is how we can get the things we need.问题是我们怎样能弄到我们需要的东西。(how 在表语从句中充当方式状语)// The s cissors are not what I need. 这把剪刀不是我所需要的。(what 在表语从句中充当宾语)// What I told him was that I would find h im a good play. 我告诉他的是我会给他找个好剧本。(what在主语从句中作直接宾语， that作为表语从句的引导词在该表语从句中不充当句子成分，不能省略)// That is what I want to tell you.那就是我想要对你讲的。(what在表语从句中充当直接宾语)// That is why she failed to pass the exam. 那就是她考试不及格的原因。(why 在表语从句中充当原因状语) “That is why...”是常用句型，意为“这就是……的原因/因此……”，其中why引导的名词性从句在句中作表语，该句型通常用于针对前面已经说明过的原因进行总结，又如： That is why you se
e this old woman before you know, Jeanne. 珍妮，这就是现在这 个老太婆出现在你面前的原因。(前文提到Jeanne对老妇人显得苍老憔悴深感诧异，说话人对她讲述了其中的原因之后，用这一句来进行概括)。// That is why I came. 这就是我来的原因。 下面是两个与“That is why...”形式相似的结构，它们与“Tha t is why...”结构之间的关系要能够辨析清楚： (1)“That is why...”与“That is the reason why...”同义，只不过从语法结构上讲，“That is the reason why...”中why引 导的是—个定语从句，将其中的the reason去掉则与“That is why...”结构一样，例如： That is (the reason) why I cannot agree. 这就是我不能同意 的理由。 (2)“That is because...”句型中从属连词because引导的名词 性从句在此作表语，这也是个常用句型，意为“这就是为什么……/ 因为……”。“That is because...”与“That is why...”之间的不同在于“That is because...”指原因或理由，“That is why...” 则指由于各种原因所造成的后果，例如： He did not see the film last night. That is because he ha d to help his littl e sister with her homework.昨天晚上他没有
