高一英语课外辅导：it 的用法
it 是近年来高考的热点之一。它不仅可以指代时间、地点、天气、距离等，还可以作形式主语和形式宾语，同时还可以用于强调句结构中。语法重点是it在强调句型中的用法，这也是高考的重要考点。为了强调句子某一成分(除谓语外)，将这一成分置于"It is (was)... that (who)..."这一句型中is (was) 之后，如果强调部分是人，既可用that又可用who连接，其余的全用that。这一句型也可用于一般疑问句、否定句和特殊疑问句。其特点是：去掉It is (was) 及that (who)这几个标志词之后，在不添词、不减词的前提下能重新排列成一个完整的句子。

情态动词精炼：1--5 CAADB5―10 AADBC 11―15 BCCBC
英语语法技巧辅导：攻击“ it 句型
1.It +系动词+过去分词+that从句
这一句型中常用的过去分词有said, reported, known, thought, believed, suggested等等。通常译为"据说(报道……)"。It是形式主语,that从句是真正的主语。如:
It is reported that a lot of people lost their jobs in the city last month.据报道,上个月这个城市的许多人都失业了。
2.It+动词(seem/appear/happen...) +that从句意为"似乎/看起来/碰巧……".如:
It seems to me that the maths problem is too easy for her.在我看来,这道数学题对她来说太简单。
3.It is /was +被强调部分+that/who从句
这一句型可以强调除谓语以外的任何成分.如:
I saw her in the post office when I was walking by.→
It was I that /who saw her in the post office when I was walking by.(强调主语)
It was her that /who I saw in the post office when I was walking by.(强调宾语)
It was in the post office that I saw her when I was walking by.(强调地点状语)
It was when I was walking by that I saw her in the post office.(强调时间状语)
注意:在这一句型中,如果被强调部分是人,可用that,也可用who连接,其余的常用that.同时在学习这一句型时还要注意其变换句型,像一般疑问句、否定句、特殊疑问句等。如: Why was it that he came late?
4.It +系动词+一段时间+since从句
意为"自……以来已有多长时间了"或"自不……以来已有多长时间了"。
注意:在该句型中若since从句的谓语动词是非延续性动词,则表示从句中的动作延续多长时间了;若since 从句的谓语动词是延续性动词或状态动词,则表示从句中的动作已结束多长时间了,译成汉语时要特别注意.如: It is just a week since we arrived in Beijing.我们到达北京刚好一星期。
It is five years since I last smoked.我戒烟已有五年的时间了。
5.It is /was /will be the first /second...time that...
该句型意为"这是/将是……第一/二……次干某事".当主句的谓语动词用is时,从句的谓语动词用现在完成时;当主句的谓语动词用was时,从句的谓语动词用过去完成时;当主句的谓语动词用will be时,从句的谓语动词用一般现在时(表示将来)。如: It is the first time that I have spoken to a foreigner.这是我首次和一位外国人交谈。
6.It is /was +形容词/名词+that从句
其中,It是形式主语,that从句是真正的主语。如: It is quite important that China becomes an official member of WTO.中国成为世贸组织的正式成员是十分重要的。
7.It is /was /will be +……+before从句
这一句型意为"还有……时间就……".如: It won't be long before you reach your goal.你离成功不远了。
8.It is up to sb. to do sth.
该句型意为"该由某人负责干某事"。如:
It is up to you to look after the children.应该由你负责照看这些孩子。
9.It is(high)time that sb. did sth.
该句型意为"是某人该干某事的时候了".这是一个虚拟语气句型,表示与现在事实相反的虚拟语气,因而that 从句的谓语动词一般用一般过去时。如: It is high time that we went to school.现在是我们该去上学的时候了。
10.It is +adj.(+of/for sb.)+to do sth.
这是有关形容词的一个复合结构句型。其中It是形式主语,真正的主语是后面的不定式。当该形容词(通常是necessary, important, difficult, hard, easy, impossible等)表示事物的特点或特征时,用for;当该形容词(通常是kind, nice, good, bad, wise, clever, silly, foolish, careless, rude, brave, cruel, careful, grateful等)表示人的特征或特点时,用of。如:
It is wise of him to make such a decision.他做出这样的决定是明智的。
It is not hard for one to do a good deed.一个人做一件好事并不难。
语法规则-情态动词
初中英语情态动词用法详解 【情态动词知识梳理】 情态动词有具体的词义，但也同助动词一样，需要与其他词语一起构成句子的谓语，另外情态动词没有人称和数的变化，情态动词后必须跟动词原形。 考点一：can，may，must等情态动词在陈述句中的用法： 1. can的用法： （1）.表示能力、许可、可能性。表示能力时一般译为“能、会”，即有种能力，尤其是生来具备的能力，此时may和must均不可代替它。如：She can swim fast, but I can’t . 她能游得很快，但我不能。I can see with my eyes.我用眼睛看。 （2）.表示许可，常在口语中。如：You can use my dictionary. 你可以用我的字典。（3）.表示推测，意为“可能”，常用于否定句和疑问句中，此时can’t译为“不可能”。如：Can the news be true?这个消息会是真的吗？—Can it be our teacher?那个人有可能是我们老师吗？—No, it can’t be our teacher. He is on a visit to the Great Wal l.不可能。咱们老师正在游览长城呢。 【例题】—I think Miss Gao must be in the library. She said she would go there.—No. She __be there, I have just been there. 【解析】根据下文“我刚去过那儿”可知，应为“不可能”，can’t表示推测[答案] 2. could的用法： （1）.can的过去式，意为“能、会”，表示过去的能力。如：He could write poems when he was 10. 他十岁时就会写诗。 （2）. could在疑问句中，表示委婉的语气，此时could没有过去式的意思。如:Could you do me 你能帮我个忙吗？—Could I use your pen?我能用一下你的钢笔吗?—Yes, you can.可以。（注意回答） 3. may的用法： （1）.表示请求、许可，比can正式，如：May I borrow your bike?我可以借你的自行车吗？You may go home now.现在你可以回家了。 【例题】—_______ I borrow your MP3?—Sure . Here you are. A. May B.Should C.Must D.
初中英语情态动词的基本用法讲解

情态动词表推测用法讲解及配套练习
情态动词must, can, could, may, might表推测的用法 情态动词中的must, can, could, may, might都表推测。其中must的可能性最大，can / could 次之，may / might最小。具体用法如下： 1.must的用法 （1）表示推测“可能性”时，意思是“一定、准是”，语气较肯定，较有把握。 He must be American. = It is certain that he is American. 他准是个美国人。 （2）must表推测只能用于肯定句。如果要表示“一定不、肯定不”的意思时，应用can’t,如询问某种可能时，应用can。 He must know my address. 他肯定知道我的地址。（一定） He can’t know my address. 他肯定不知道我的地址。（一定不） Can he know my address? 他知道我的地址吗？（询问可能性） （3）must表示推测时，可以推测现在/正在发生的动作/过去发生的动作。 He must have a car now. （现在）他一定有辆小汽车。 He must be doing his exercises in the classroom.（正在进行）他一定在教室里做练习。 He must have finished the work.（过去发生）他一定已完成了工作。 注：must表示推测时很少用于将来的情况。一般不用He must come tomorrow.可用It`s certain / I’m sure that he will come tomorrow. （4）在反意疑问句中，当附属部分含有表示推测意义的must时，疑问部分的助动词应与must后面的动词在非推测情况下的用法保持一致。 He must be a worker, isn’t he? （现在）他准时个工人，是吗？ It must have rained last night, didn’t it? （过去）昨晚一定下雨了，是不是？ You must have learned English for many years, haven’t you? （完成时）你一定学了好多年英语，是吗？ 2.?can / could的用法 （1）can表示推测“可能性”时，往往用于否定句或疑问句。Can’t“一定不”，语气很肯定。can在疑问句中意思是“会、可能”。 He can’t be at home. = It is impossible that he is at home. 他一定不在家。 （2）can /can’t后可接进行时/完成时，表示对现在发生的动作或过去发生的动作进行推测。They can’t be reading in the library. 他们一定不在图书馆读书。 He can’t have gone to Shanghai for I saw him a minute ago. 他不可能去了上海，我刚才还看见他。 It’s so late. Where can she have gone? 天晚了，她可能去哪儿了呢？ （3）在反意疑问句中，当陈述部分含有表示推测意义的can’t时，疑问部分的助动词应与can’t后面的动词在非推测情况下的用法保持一致. He can’t be a teacher, is he? 他不是教师，是吗？ She can’t have finished her homework, has she? 她一定没有完成家庭作业，是不是？ （4）could可用于表示某事有可能发生或可能是事实。 Don’t eat it. It could be poisonous. 不要吃它，可能有毒。 The plane could be delayed by fog. 飞机可能会因为雾晚点。 （5）could还可以用于表示客气、委婉、礼貌的请求语气。 Excuse me, could you tell me the way to the bus station?
