高考英语现在完成时真题汇编(含答案)及解析

高考英语现在完成时真题汇编(含答案)及解析 一、单项选择现在完成时 1.More and more cancer patients _________ in hospital owing to polluted environment and people’s bad lifestyles. A.treated B.have treated C.have been treated D.had been treated 【答案】C 【解析】 【详解】 考查时态语态。句意:由于被污染了的环境和人们糟糕的生活方式,越来越多的癌症病人正在医院里接受治疗。本句主语more and more cancer patients与动词treat构成被动关系,要使用被动语态;而且很多病人接受治疗是已经发生的事情,要用完成时表示,所以本句使用现在完成时的被动语态,故选择C项。 2.The disease is a huge blow for the farmers. Hundreds of them ______ their animals, livelihood and hopes destroyed and many others fear they _____ the same fate. A.have seen; will suffer B.saw; suffered C.had seen; was to suffer D.see; suffer 【答案】A 【解析】 【详解】 考查时态。句意:这种疾病对农民来说是一个巨大的打击。数以百计的人目睹了他们的动物、生计和希望被摧毁,还有许多人担心他们会遭受同样的命运。结合句意可知第一空用现在完成时态;第二空用一般将来时态。故选A。 3.She is a strong-willed woman and not once _______ in to any difficulty in her life. A.she has given B.did she give C.she gave D.has she given 【答案】D 【解析】 试题分析:考查动词时态和倒装句。句意:她是个意志坚强的女人,一生中一次也没有向任何困难屈服过。And 连接的两个并列句中,否定副词 not once放在了第二个句子的句首,所以后面部分用部分倒装语序,此外第一句的时态是一般现在时,后句又出现了in her life,所以句子应该用现在完成时,表示到现在为止,故正确答案为D选项。 考点:考查动词时态和倒装句 4.The Reform and Opening-up, having passed its brilliant age of 40 years ,____the backward situation of the Chinese nation and influenced the world. A.change B.changes C.has changed D.have changed

A.finish B.will finish C.have finished D.finished 【答案】C 【解析】 【详解】 考查时态。句意:到目前为止,我们已经完成了三分之二的项目,我们一定会按时完成。根据句中时间状语so far可知用现在完成时。故选C。 【点睛】 本题考查现在完成时,现在完成时是“过去的动作或状态持续到现在并且已经完成”。判断现在完成时的标志词有already , ever , never , yet , just , before, still , lately ,since , for a long time ,up to now, until, so far, in the last few years/weeks/mouths , till now, recently等,考生在平时学习英语过程中要多注意积累。本题只要抓住句中时间状语so far(到目前为止)就可以判断出用现在完成时。 2.It is the fourth time that Tom ______ in the maths exams. A.failed B.has failed C.had failed D.have failed 【答案】B 【解析】 【详解】 考查固定句式中的时态。固定句式:It is/was the+序数词+that 从句;句意:这是某人第几次做某事的时候了。如果前面是is,后面使用现在完成时;如果前面是was,后面使用过去完成时。本题前面是is,故使用现在完成时,主语是第三人称单数,故B正确。句意:这是这个星期里他第四次打电话给你了。 【点睛】 固定句式:It is/was the+序数词+that 从句;句意:这是某人第几次做某事的时候了。如果前面是is,后面使用现在完成时;如果前面是was,后面使用过去完成时。(1)It is the first time that I have come to the Great Wall. 这是我第一次到长城去。(2)It was the first time that he had visited the Great Wall.那是他第一次参观长城。 3.The Reform and Opening-up, having passed its brilliant age of 40 years ,____the backward

英语语法-现在完成时用法及习题

目录 1现在完成时的构成 (2) 2现在完成时的用法 (5) 3 使用现在完成时需注意事项 (7) 4过去完成时与现在完成时的比较 (12) 练习题 (13) 答案 (16)

现在完成时对于我们来讲是所有时态中最难掌握的一种。因为它并不是表示发生于某一时间的事情,而是既涉及过去,又联系现在的一种时态。请参见下列三个例句: 例:1.I live in Beijing. 我住在北京。 2.I lived in Beijing. 我住过北京。(我在北京住过。) 3.I have lived in Beijing. 我一直住在北京。 例1.的live是一般现在式,表示“我现在住在北京”这一事实。 例2.的lived是过去式。这句只是表示在过去的某一时期我在北京住过,至于现在住不住在北京则不清楚。 例3.的have lived是现在完成时,表示我在过去的某一时间开始住在北京,现在也住在北京。表示从过去到现在的一种继续状态。 1现在完成时的构成 现在完成时的形式是“have (has)+过去分词”,表示继续、完了、结果和经验等四种意思。 现在完成时的否定句是在have(has)的后面加上not,疑问句是将have(has)置于主语之前。 1现在完成时的肯定句 句型:

We have lived in Beijing. 我们一直住在北京。 He has lived in Beijing. 他一直住在北京。 过去分词的三种用法 过去分词有下列三种用法(过去分词的构成详见第六章):1.构成现在(过去)完成时 have(has)+过去分词~ I have written the letter. 我写完这封信了。 2.被动语态:参见第十三章 be + 过去分词~ He was looked after.他受到照顾。 3.用于形容词 This is a broken chair. 这是一张坏的椅子。 2现在完成时的否定句 句型:主语+have(has)+not +过去分词~.

现在完成时被动语态教学设计

高中英语语法《现在完成时的被动语态》教学设计 一、教材分析 本节课的授课内容为被动语态中的一个重点也是难点的内容:现在完成时被动语态的学习及其应用。对于该内容学生半知半解,加上语法容易让人觉得枯燥,学生对此内容有排斥畏难心理。所以教学中将语法知识的传授和语言基本技能的学习结合到一起,注重学习语法与语言的运用。采用任务型教学法、情景教学法和小组合作探究学习法,让学生亲身去感知、领悟知识和运用知识,从而扩大课堂的语言输入量及学生的语言输出量,使其内容更加丰富,降低了语法学习的难度,同时也使语言学习和运用语言的过程成为一种栩栩如生的互动体验,提高了学习效率。 二、学情分析 授课对象为高一级的学生,他们来自全区各地初中,大部分学生的基础知识仍然较为薄弱,运用英语进行交际活动的能力较差,主动学习的动力不够,然而他们学习比较认真,渴求知欲旺盛,思维比较活跃。部分学生的基础较好,能主动配合老师。所以只有设臵使他们感兴趣的活动,利用发生在学生身边的事情——教室的环境布臵和学校艺术文化节作为语法学习的载体,因材施教,让学生明白所学语言知识的实用性,这样才能激发学生学习的积极性,并在师生互动、生生互动中实现教学任务和目标。 三、教学目标 知识与技能:1.让学生弄清楚现在完成时被动语态的结构和用 法; 2.重点是现在完成时被动语态的应用。 过程与方法:1.培养学生自主学习、协作学习和探究的能力; 2.培养学生分析问题、解决问题、归纳问题的能 力。 3.提高思维能力和运用英语的综合能力。

情感价值观:通过本节课的学习,培养学生热爱学校积极参与 学校活动的情感。 四、教学重点和难点 现在完成时被动语态的基本构成与实际应用。 五、教学策略和方法 本节课的教学以学生为中心,以教室的环境布臵和学校艺术文化节为载体,使课堂教学过程成为学生自主地进行信息加工、知识意义构建、归纳能力发展的过程。教师在教学过程中则适时介入,引导、启发、组织、帮助、促进。随堂进行小组指导,一方面参与学生的讨论,更给学生以个别辅导,以帮助学生解决学习过程中的难题。通过演示法把制作的课件、学生的作文等显示给学生看,便于学生对知识的把握,并从中获得启迪,从而解决问题。通过小组协作法分析问题、解决问题,从而内化而形成学习成果,并将其在全班学生中展示,使学生获得成功的喜悦,从而激发学生的后续学习热情。通过任务驱动教学法将所要学习的新知识隐含在语言操练之中,学生通过对呈现的图片进行分析、讨论,并在老师的指导、帮助下用本节课的语法对图片进行描述,以达到对语法项目的操练,最后通过任务的完成而实现对所学知识的意义建构。 六、板书设计 现在完成时被动语态的基本结构:have/has been done 七、教学过程 Step1 Revision (复习)(6分钟) 本单元学习的话题是计算机,计算机的应用很广泛,让学生在阅读里面找出介绍计算机应用的句子,并齐读句子:?The computers have been used in communication, finance and trade. ?The computers have been put into robots. ?It has been used to make mobile phones as well as help with
