Hurry up.2从这儿到你们学校远吗不远,大约一公里;Is it far from here to your school No, it isn’t. It’s about a kilometer.3从我家到颐和园去很近;It is very near from my home to the Summer Palace.4天正在下雨;It’s raining now.5电灯是爱迪生发明的;It was Edison who invented the electric light.6我认为学习一门外语是很重要的;I think it important to learn a foreign language.7他通常一天读两次英语;He made it a rule to read English twice a day.8从我家去天安门广场坐公共汽车大约要一个小时;It takes about an hour to go from my home to the Tian’anmen Square by bus.反意疑问句反意疑问句相当于“对不对”“好不好”“行不行”,用yes或 no 回答;由两部分组成,前一部分是陈述句,后一部分是附加疑问短语,中间用逗号隔开,所以反意疑问句又叫附加疑问句;通常的形式是:肯定的陈述句+否定的附加疑问,或否定的陈述句+肯定的附加疑问;如:He studies English, doesn’t heHe doesn’t study English, does heThey are from America, aren’t theyThey are not from America, are they反意疑问句的主要形式:1.如果主句是be或其他助动词如can, shall, will 等,其反意疑问句用同一助动词; 如:We are late, aren’t weYou haven’t met my wife, have youHe can drive a car, can’t heThey used to have difficulty in just making ends meet, didn’t usedn’t theyYou’d better eat with knives and forks, hadn’t you2.如果主语带有seldom, hardly, never, rarely, few, little等否定词或半否定词时,因为主句本身具有否定意义,附加疑问部分的动词用肯定式,如:We seldom go to the cinema, do weSue almost never worked, did she3.如果主句部分是“I am…”结构,由于”am not” 没有相应的缩略形式,附加疑问部分一般用aren’t I 代替;如:I am your friend, aren’t II’m late, aren’t II am a student, aren’t I在祈使句中的附加疑问部分一般用will you, won’t you.4. 在祈使句中的附加疑问部分一般用will you, won’t you.如:Sit down, will youHave some tea, won’t youOpen the window, won’t you这种句子可以理解为: Will you do something如:Will you open the window注意:否定的祈使句之后,只能用will.Don’t forget, will youDon’t make so much noise, will you5.以Let’s… 开头的祈使句,肯定的用shall we否定的用all right或OK,如:Let’s go back to our seats, shall weLet’s not have hot food this t ime, OK all right这种句子可以理解为:Shall we do something,如:Shall we go back to our seats.这样有助于理解和记忆;注意:Let’s 与Let us 的区别:Let’s包括听话人在内,应用shall we, 而Let us 不包括听话人在内,表示“请你让我们…”,要用will you.如:Let’s watch the news on TV, shall we 表示建议Let us watch the news on TV, will you 表示请求6.主句是I suppose, I think, I believe等时,附加疑问部分则往往与that 从句中的主语和谓语动词保持对应关系,但要注意否定的转移;如:I suppose that you know the meaning of the word, don’t you这句话明显是要问“你是不是知道”而不是问“我是不是这样认为”I don’t think that you have read the book, have you7.当主句的动词have 表示“拥有”时,附加疑问既可用have, 也可用do,如:You have a color TV set, haven’t you/don’t you当主句的have不表示“拥有”而表示其他意思时,附加疑问要用do,如:You had a cold yesterday, didn’t youThey don’t have coffee with breakfast, do theybe句型的反意疑问句,用there 作主语;如:There is something wrong, isn’t thereThere won’t be any trouble, will there 不会有任何麻烦,是吗9.陈述部分的主语是everyone, someone, anyone, no one, nobody等不定代词时,其疑问部分的主语可用he, 也可用they.Everyone knows it, doesn’t he/don’t they英语反意疑问句的回答有点和汉语的相反;但一定要记住:只要回答是肯定的,都用yes,只要回答是否定的,都用no;这在主句是否定句的时候要特别注意;例如:Mr. Jones can’t speak French, can he No, he can’t.琼斯先生不会讲法语,对吗对,他不会讲法语;Mr. Jones can’t speak French, can he Yes, he can.琼斯先生不会讲法语,对吗不,他会讲法语;This is not a door, is it -Yes, it is. It is an iron door.这不是门,对吗不,这是门;是扇铁门;。

it的用法A. 语法要点剖析在英语中, it的用法相当广泛, 它既可用作代词, 如人称代词、指示代词、非人称代词,也可用作引导词和强调结构中的强调词。

一.it作代词1. 用作人称代词,代替前文提到过的事物。

如,--Whose exercise-book is that?--It’s hers.--What’s this?--It’s a flag.3.用作非人称代词,可指时间,距离,度量,价值,自然现象等。

其形式为“It is(was)+被强调的部分+that (who/whom)+句子的其他成分”。

如I met her at the airport yesterday. 这个句子就可借助it改为下列几种形式。

各强调一个不同的成分。

It was I that(who) met her at the airport yesterday.(强调主语)It was her that(whom) I met at the airport yesterday.(强调宾语)It was at the airport that I met her yesterday.(强调地点状语)It was yesterday that I met her at the airport.(强调时间状语)注意:1.强调“not…until”结构时,要用固定的强调句型“It is/was not until…that…”。

如,Was it in 1969 that the American astronaut succeeded in landing on the moon?3. 特殊疑问句中只有疑问词可以强调,其强调结构是:“疑问词+is/was it+that…?”如,When was it that you got to know her?4. 注意与“It is/was…before…”句型的区别。

如,⑴It was two days ago that he came to Wuhan.⑵It is three months before she gets her licence.句⑴去掉“It was…that”后则成为He came to Wuhan two days ago.(√)句⑵去掉“It is…before…”后则成为She gets her licence three months.(×)B. 高考试题1.
