1.【我们的英语已经上了一个半小时和我们一个半小时之前上的,用英语
你问的英语是英语课吗?我们的英语已经上了一个半小时.(用完成时)We have had the English class for one and half an hour.我们一个半小时之前上的.(用一般过去式)We started our English class one and half an hour ago.你同学通常什么时候做作业.:When does your classmate usually do his/her homework?(一个同学)When do your classmates usually do their homework?(泛指其他同学)。
2.【强调句用英语怎么说
强调句型的构成是:It is (was) + 被强调部分+ that (who) + 句子的其他成分.被强调的部分放在 It is (was) 之后,其它部分置于that之后.被强调部分可以是主语,宾语,表语或状语.强调的主语如果是人,可以由who代替that.1.被强调的成分举例:原句:Tom found my pen in the classroom yesterday.强调主语:It was Tom who / that found my pen in the classroom yesterday.强调宾语:It was my pen that Tom found in the classroom yesterday.强调地点状语:It was in the classroom that Tom found my pen yesterday.强调时间状语:It was yesterday that Tom found my pen in the classroom.2.强调句型的一般疑问式:直接把is或was提到it之前即可.例如:Was it Tom that found your pen in the classroom yesterday?3.强调句型的特殊疑问式:特殊疑问词+ is (was) it + that +句子的其他成分.特殊疑问词即是被强调的成分.例如:Who was it that found your pen in the classroom yesterday?4.that (who) 有时可以省略:这种强调句型中的that或who有时可以省略.例如:It was my brother (that / whom) you saw the other day.5.强调原因状语从句要注意:若从句由as或since引导,强调时则改为because,这是因为,because引导的原因从句表示的意义非常强烈,符合强调句的目的.例如:As she got up late,she missed the first bus.变为:It was because she got up late that she missed the bus.6.强调句的否定转移:有些否定句在变成强调句时,要把否定转移到被强调的词语之前.尤其是“not。
until。”句式的强调要特别注意.例如:He didn't realize his mistake until the teacher had told him.变为:It wasn't until the teacher had told him that he realized his mistake.【注意】 在强调句式中,虽然not被提前,但“not。
until。”句型不要倒装.高考中强调句型考查热点 考点一:强调句型的基本结构强调句型“It is / was + 被强调的成份 + that + 其他成份”用来强调主语、宾语和状语等成份.that只起连接作用,不作成份,但不能省略.有时强调的部分比较特殊,如主语从句、状语从句、名词、不定式短语、V-ing的复合结构等.如:It was in the library that I saw her yesterday.我昨天正是在图书馆见到她的.考点二:特殊句式中的强调句型1.如果强调的是特殊疑问句中的疑问词,表示“到底”、“究竟”等语气时,就用如下结构:“特殊疑问词 + is / was + it + that + 该句的其余部分”.如:How is it that you usually go to work?你通常是怎样去上班的?2.在强调“not。
until”结构中由until所引导的短语(或从句)作时间状语时,要用固定的强调句型:“It + is / was + not until。+ that + 该句的其余部分”,that所引导的从句中的谓语动词用肯定式.如:His father didn't come back from work until 12o'clock.= It was not until 12 o'clock that his father came home form work.直到12点他的爸爸才下班回家.考点三:强调句型与时间状语从句、定语从句的判断强调句型要注意和it代表时间、距离、温度、自然现象、具体事物或人物等时所构成的各种句型的区别.试比较:It was on March 1 that I had my hair cut.(强调句)It was March 1 when I had my hair cut.(后面是定语从句)判断是否是强调句,可采用“还原法”.如果还原为一般句式后,句子各种成份完整,则是强调句.否则不是.如第一句可还原成:I had my hair cut on March 1.考点四:偶尔考查谓语动词的强调句式英语中常用助动词do、does或did强调谓语.如:He did go to the airport yesterday,but he didn't find you.他昨天确实去了机场,但他没有找到你.。
