2015高考英语真题分类汇编

专题一冠词、名词和主谓一致 1.【2015·湖北】21.When he was running after his brother, the boy lost his ___ and had a bad fall. A.balance B .chance C .memory D .place 【答案】A 【考点定位】名词词义辨析 【名师点睛】本题侧重考查在特定的语境中辨析名词词义的能力。四个选项都可以跟前面的动词lose 搭配。考生应抓住题干中关键信息“had a bad fall(重重地摔了一跤)”,不禁会产生疑问:怎么会摔了一跤呢?然后根据搭配l ose one’s balance“失去平衡”锁定正确答案。 2.【2015·湖北】22.He gave himself a new name to hide his ____ when he went to carry out the secret task. A.emotion B.talent C.identity D.treasure 【答案】C 【解析】 试题分析:句意:他执行一项秘密任务时,给自己起了一个新的名字来掩盖身份。A项“情绪”;B项“才能”;C项“身份”;D项“财富”。故选C项。 【考点定位】名词词义辨析 【名师点睛】考生解答本题的关键是抓住题干中的关键词“secret task(秘密任务)”和“gave himself a new name(给自己取了个新名字)”,然后推知肯定是为了“hide his identity(掩藏身份)”,从而锁定正确答案。 3.【2015·安徽】30.There is no need to tell me your answer now. Give it some ______ and then let me know. A. thought B. support C. protection D. authority 【答案】A 【解析】 试题分析:句意:现在没必要告诉我答案,你再思考一下,之后告诉我。A思考;B支持;C保护;D 权威,当局。这里指让对方再好好想想,故选A。 【考点定位】考查名词辨析 【名师点睛】本题考查名词辨析。该种题型要求学生积累一定的词汇量,四个词的意思分别是“思考”;“支持”;“保护”和“权威”;其次,做题时需要结合句意进行综合考虑。根据第一句和“and then let me know”可知,现在不急着告诉“我”答案,由此可知是让对方再想想。 4.【2015·江苏】3 5.—Go and say sorry to your Mom, Dave. —I’d like to, but I’m afraid she won’t be happy with my ______ . A. requests B. excuses C. apologies D. regrets 【答案】C 【解析】 试题分析:句意:—Dave,去跟你的妈妈道歉。—我想这样做,但是我担心她对我的道歉不满意。A项“请求”;B项“借口”;C项“道歉”;D项“遗憾,后悔”。故选C项。 【考点定位】名词词义辨析 【名师点睛】本题侧重考查在情景交际中辨析名词词义的能力。语境较为简单,考生只要抓住上文中的关键词“say sorry to”就可以锁定正确答案。因此,考生可以试着将词汇放在日常的情景交际中进行操练,加强对词汇的语境理解,可以达到事半功倍的效果。 5.【2015·江苏】32.Some schools will have to make ______ in agreement with the national soccer reform. A. judgments B. adjustments C. comments D. achievements 【答案】B 【解析】 试题分析:句意:为了与国家的足球改革相适应,一些学校必须做出调整。A项“判断,决断”;B项“调整”;C项“评价,评论”;D项“成就”。故选B项。 【考点定位】名词词义辨析 【名师点睛】本题侧重考查在特定的语境中辨析名词词义的能力。四个选项都可以跟前面的动词make 搭配。因此,考生除了要充分利用特定语境理解词义,还应注意多积累可以跟同一动词搭配的名词。另外还可以利用固定搭配排除C项make本题侧重考查在特定的语境中辨析名词词义的能力。comments on“对……做出评价/评论”,缩小正确答案的范围。

The girls on the Wesleyan Academy softball were waiting for their next turns at bat during practice, stamping their feet to stay warm, Eighth-grader Taylor Bisbee shivered(发抖) a little as she watched her teammate Paris White play. The two didn‘t kn each other well — Taylor had just moved to town a month or so before. Suddenly, Paris fell to the ground,―Paris‘s eye rolled back,‖ Taylor says. ―She st was an emergency.‖ It certainly was, Paris had suffered a sudden heart failure. Without immediate medical care, Paris would die. At first no one moved. The girls were in shock. Then the softball coach shouted out, ―Does anyone know CPR?‖ CPR is a life-saving technique. To do CPR, you press on the sick person‘s chest so that blood mov through the body and takes oxygen to organs. Without oxygen the brain is damaging quickly. Amazingly, Taylor had just taken a CPR course the day before. Still, she hesitated. She didn she knew it well enough. But when no one else came forward, Taylor ran to Paris and began doing CPR, scary. I knew it was the difference between life and death,‖ says Taylor. 1. Two more ran to get the Taylor‘s swift action helped her teammates calm down. One girl called 91 school nurse, who brought a defibrillator, an electronic devices(器械) that can shock the heart back into work.

My team s Experts say Paris is right: For a sudden heart failure, the single best chance for survival is having someone nearby step in and do CPR quickly.

高考英语阅读理解真题汇编及答案解析(十一)

高考英语阅读理解真题汇编及答案解析(11) 摘要:阅读理解题的“三步法”:1.略读。目的是了解短文的主旨大意和便于迅速掌握短文的语篇结构。2.查读。同学们要先通读题干,做到胸中有数;再将短文读第一遍,锁定某些特定信息进行快速阅读,迅速选出最佳答案;先易后难,先做细节题,后做推论题。3.重读短文重点。核查。同学们做题的关键是看清题目的要求,读准的关键是分清句子的结构和确认词性词义。 When Andrea Peterson landed her first teaching job,she faced the daunting task of creating a music program with almost no money for equipment or supplies in a climate where standards-based learning was the focus and music just provided a break for students and teachers. For her drive and creativity in overcoming those challenges,she’s been named national teacher of the year. Principal Waynes Kettler said he’s worked with many outstanding teachers in his22years as an educator,but Peterson is“just that one step above anybody I’ve ever worked with before.” Kettler and others at Monte Cristo Elementary School talk about the ways she has introduced the learning from other classrooms into her music program and her creativity in working around things such as the lack of money for new music. When students were reading S.E.Hinton’s novel The Outsiders in their regular classroom, Peterson helped them write a30-minute play with scenes from the book.Then they chose three Broadway tunes that focused no race,equality and social justice,the themes of the book.Peterson composed two other songs herself after classroom discussions about the play and the book. The honor means a lot to residents of Granite Foils.It’s inspiring to know that people from small towns own even win national honors. As national teacher of the year,Peterson will spend the next year outside the classroom, as a national and international spokeswoman for education. Not surprisingly,She is a big believe in the value of arts education.She said it’s essential for schools to offer classes such as art or music and physical education because for some kids one of those subjects is the only thing that motivates them to come back to school day after day. 65.The underlined word“daunting”in Paragraph1most probably means__________.

A.rarely will we find B.rarely we will find C.rarely will find we D.rarely find we will 【答案】A 【解析】 选A考查倒装。句意:我们追求幸福,想着总有一天会找到幸福。但是,我们几乎不能通过一味追求幸福而找到幸福。否定副词放在句首时,句子要部分倒装。A项正确。 2. How happy we are!The winter holiday we have been looking forward ____soon. A.has come B.to have come C.to coming D.to will come 【答案】D 【解析】 【详解】 考查时态。句意:我们真开心啊!我们一直期待的寒假很快就要来了。本句中定语从句的先行词是the winter holiday,关系代词that/which指代先行词在句中作为动词短语look forward to的宾语,被省略掉了。句中的come是谓语动词。根据句意可知,寒假还没有到来,故用一般将来时。故D正确。 考点:考查句子结构和时态 3.–Peter, do you know how to download the new software? –Certainly. I _____ you the steps. A.show B.am showing C.will show D.have shown 【答案】C 【解析】 试题分析:考查动词时态与体态辨析。A. show,一般现在体;B.am showing,现在进行体;C. will show,一般将来体;D. have shown,现在完成体。句意:—彼得,你知道如何下载最新的软件吗?—当然。我会教你步骤。由句意可知show动作发生在说话动作之后,说话者的时态是一般现在时,故这里是用将来时时,表示将会做。故选C。 考点:考查动词时态与体态辨析。 4.Turn on the television or open a magazine and you ________ advertisements showing happy families.

2018新课标Ⅰ卷 During my second year at the city college, I was told that the education department was offering a “free” course, called Thinking Chess, for three credits. I41 the idea of taking the class because, after all, who doesn’t want to42 a few dollars? More than that, I’d always wanted to learn chess. And, even if I weren’t43 enough about free credits, news about our 44 was appealing enough to me. He was an international grand master, which 45 I would be learning from one of the gam e’s46 I could hardly wait to 47 him. Maurice Ashley was kind and smart, a former graduate returning to teach, and this 48 was no game for him; he meant business. In his introduction, he made it 49 that our credits would be hard-earned. In order to 50 the class among other criteria, we had to write a paper on how we plan to 51 what we would learn in class to our future professions and 52 .to our lives. I managed to get an A in that 53 and leaned life lessons that have served me well beyond the 54 . Ten years after my chess class with Ashley, I' m still putting to use what he 55 me:“the absolute most important 56 that you learn when you play chess is how to make good 57 . On every single move you have to 58 a situation, process what your opponent (对手) is doing and 59 the best move from among all your options.” These words still ring true today in my 60 as a journalist. 41.
