高中英语阅读理解练习题(有答案)

一、高中英语阅读理解1.阅读理解Most adults find it hard to recall events from their first few years of life and now scientists have found exactly when these childhood memories fade(消失).A new study has found that most three-year-olds can recall a lot of what happened to them over a year earlier, and these memories persist while they are five and six, but by the time they are over seven, these memories decline(衰退) rapidly.Most children by the age of eight or nine can only recall 35% of their experiences from under the age of three, according to the new findings.The scientists behind the research say this is because at around this age the way we form memories begins to change. They say that before the age of seven children do not have a sense of time and place in their memories. In older children, however, the early events they can recall tend to be more adult-like in the way they are formed. Children also have a far faster rate of forgetting than adults. The findings also help to explain why children can often have clear memories of events but then forget them just a couple of years later.The youngsters first visited the laboratory at the age of three and discussed six unique events from their past, such as family outings, trips to the zoo, and the first day of school. The children then returned for a second session between the ages of five and nine to discuss the same events. The researchers found that between the ages of five and seven, the amount of memories the children could recall remained between 63 -72 percent. However, the amount of information eight-to nine-year-old children could recall dropped to 35 and 36 percent.(1)What does the new study tell us?A.Childhood memories decline with years.B.Three-year-old kids are the cleverest.C.Childhood memories can fade easily.D.Some adults cannot recall past events.(2)What does the underlined word "persist" in Paragraph 2 mean?A.Change.B.Remain.C.Appear.D.Return.(3)What can we learn from Paragraph 4?A.Adults cannot have clear memories of past events.B.Children can think like adults when they get older.C.Children under 7 years old have different ways of forming memories.D.Children often forget things because they have no idea of time or place.(4)In the second session, nine-year-old children _________.A.refused to discuss the same eventsB.remembered all their family outingsC.could recall 72 percent of their past eventsD.only remembered a small part of their past events【答案】(1)A(2)B(3)D(4)D【解析】【分析】本文是一篇说明文,介绍了记忆消失的一些知识。

高三英语阅读理解专项训练及答案含解析一、高中英语阅读理解1.阅读理解Average humans can consume 15 or more drinks in plastic bottles a month. If you were born after 1978, and live until 80 years old, you will leave behind a minimum of 14,400 plastic bottles on this planet. These bottles take hundreds of years to break down into tiny pieces of plastic, never to completely disappear. Most of the waste is consumed by fish and birds, which has shortened their lifetime greatly.The Plastic Bottle Village is just a great idea that might finally save us from being buried in plastic. It's a community in Panama that is going to be made of used bottles. The design process begins with building steel frames, which are then filled with these bottles. Once this step is complete, and electrical and plumbing (管道装置) lines are put inside, the plastic walls are covered by concrete—both inside and outside. So no one will actually be able to tell that the walls are made of plastic. Besides, the material will keep the house 17°C cooler than the outside, which is the biggest benefit to people living inside.The village is the brainchild (主意) of Robert Bezeau with the intention of setting up several environmental projects. Having started a recycling program four years ago, during which a number of plastic bottles were collected, he started to think of how they could be put to use. Soon enough, he decided to use them to build houses, and came up with a basic idea for the construction process.The project hopes to make people conscious of the waste that these bottles create so that they can do more to protect the environment. The village will also create an education center that will teach individuals from the world how to reuse plastic bottles as construction materials for shelter. Recycled bottles could neutralize the negative effect of your passage on this planet, and move closer to leaving only your “footprints”.(1)What does Paragraph 1 intend to tell us?A. The reason for buying fewer drinks.B. The difficult situation of wildlife.C. The amount of plastic waste.D. The seriousness of plastic pollution.(2)What is the biggest benefit to people living in the Plastic Bottle Village?A. The house will be much cooler than normal ones.B. The material of construction will be reduced a lot.C. The newly-made house can save a lot of electricity.D. The waste of the house can be consumed by fish and birds.(3)Which of the following words can best describe Robert?A. Creative.B. Courageous.C. Enthusiastic.D. Sensitive.(4)The main purpose of Robert's projects is toA. provide shelter for localsB. reuse all deserted plastic bottlesC. popularize the use of plastic bottlesD. raise people's environmental awareness【答案】(1)D(2)A(3)A(4)D【解析】【分析】考查环保类文章。

【英语】高考英语高中英语阅读理解的技巧及练习题及练习题(含答案)一、高中英语阅读理解1.阅读理解Castle Dale is a small town in central Utah. My grandpa's farm is a few miles to the north. I grew up there. Milking a cow, feeding the chickens and cutting firewood were daily routines. Grandpa had me carrying a broom to do snow cleaning when it was actually taller than I was. This was the work kids like me learned to do at a young age.I was tall, very tall at a really young age. My unusual height caused people to look, ask questions, laugh, tease, and sometimes even challenge me to fight. I was teased cruelly as a kid. It wasn't fair, I knew, but that was just the way it was. Luckily, I was taught at a very young age a very important lesson. I am different and that's Okay—I'm unique and I matter. No one could ever take that away from me. I knew this then, and I know this now. That alone helped me through the frustrations and heartaches of normal life.When I was in junior high school, I realized something else that helped me cope. Most teasing came from one of two places—people who were either jealous or ignorant (愚昧). I couldn't change the way they were, but I could change the way I felt. I was not going to feel bad because of their ignorance or jealousy. It wasn't worth it. Realizing this didn't stop them, or change the fact that these comments hurt. It did, however, give me a way to understand these people and deal with their treatment in a way that was okay for me.These things still happen today. It will probably happen the rest of my life. I will always be 7 feet, 6 inches (2.29 meters) tall. I wouldn't change that for anything. People will always look because it is not every day that you see someone that tall. I learned that at a young age and I now try to teach my own children that they are unique and they matter. That is the message I give to you. Regardless of your race, religion, background, or circumstances ... Being different is okay.(1)The author mentioned his hometown to show us _______.A. he is from an ordinary familyB. his grandpa is strict with himC. he loves this lovely small townD. he had to do a lot of labor work(2)The author was often teased because _______.A. he grew up in a small townB. he was much taller than othersC. he fought with people easilyD. he didn't want people to watch him(3)What was the author's attitude towards being teased?A. He accepted the fact of being different and let it go.B. He felt angry failing to change others' opinions.C. He felt hurt hearing people's negative comments.D. He hated people's ignorance and jealousy.(4)Which of the following may best describe the theme of the passage?A. Everything comes to the man who waits.B. It is the first step that is troublesome.C. Speech is silver, silence is gold.D. Keep your head up.【答案】(1)A(2)B(3)A(4)D【解析】【分析】本文是一篇记叙文,讲述了作者从小到大由于身高的特殊性受到了很多嘲笑和欺辱,但是作者并未此而感到沮丧.反而认识到不管一个人的种族、宗教、背景或者所处的环境如何,与众不同也是一种生活态度。

高中英语阅读理解练习题100(附有答案)

1阅读理解技巧阅读理解题是考查学生对活的语言材料的理解能力,即通过阅读材料获得信息的能力。

具体说来,阅读理解能力测试的主要要求是:(1)掌握所读材料的主旨大意,以及用以说明主旨大意的事实和细节;(2)既理解具体事实,也理解抽象的概念;(3)既理解字面意思,也理解深层含义,包括作者的态度、意图等;(4)既理解某句、某段的意义,也理解全篇的逻辑关系,并能根据文章进行推理和判断;(5)既能根据材料所提供的信息去理解,也能结合中学生应有的常识去理解。

根据这几项能力测试的要求,试题中常采用如下几种题型:事实询问题、推理判断题、数据推算题、识图解意题和主旨大意题。

根据这一测试要求和题型设计,答题时可以采取如下解题技巧和对策。

1.首先解题时要充满自信。

由于平时有些同学对做阅读理解时存在一种畏惧心理,因此考试做题时心理就难免会产生紧张感,特别是阅读时再遇到几个生词就头脑发胀,从而使自己的思路更加模糊不清。

其实这是完全没有必要的,因为阅读中遇到几个生词或几个难以理解的句子是常有的事,也是正常现象。

因为按大纲要求,试卷中允许有不超过3%的生词,只要认真分析,仔细阅读,这些生词和句子很可能并不影响你的解题。

所以答题之前首先要有必胜的信心。

2.扫读全文,理解全文主旨大意。

拿到一篇文章,首先要快速扫读全文,虽为扫读,但不可漫不经心,阅读时也应聚精会神,力求可能多地获取材料信息,只是这次遇到生词和难句先不必去处理,不要因纠缠文中的个别生词和难句而影响了对全文的主旨大意的了解。

3.对症下药,各个击破。

了解全文的大概意思之后,再把短文的问题简单看一遍,弄懂题意,然后带着问题再去寻读全文。

这次阅读过程中要善于抓文章中的关键词句。

寻读也就是迅速的查找需要了解的信息,是为某些特定的问题而阅读,因此阅读时要有较强的针对性,对与问题有关的数据,词句等仔细阅读,认真理解,同时结合不同考查内容的题型,采取如下解题对策:(1)事实询问题:这类试题通常是以疑问词what,who,when,where,why,h ow等引起的特殊问句,就文章中某一词语、某一句子、某一段落或某一具体细节和事实进行提问。

高考英语阅读理解题20套(带答案)一、高中英语阅读理解1.阅读理解Years ago, students applying to colleges and universities had to have their applications and personal essays printed out and then “snail-mailed”. Flash forward to today's world of Facebook, Instagram and WeChat, where photos, videos and mobile phones rule. Fortunately, several new tools are making it easier for college applicants to use technology to show off their personalities, skills and creativity.ZEEMEEOne of the more popular innovations in college applications is ZeeMee, a free mobile app that allows students to upload personal profiles and videos to create visual resumes. More than 220 colleges and universities offer a ZeeMee option as part of the application process. The video can show the unique creative aspects of the applicants.THE COALITION LOCKERAnother relatively new tool comes from the Coalition for Access, Affordability and Success, now used by more than 110 member colleges and universities. Among the group's stated goals are getting students engaged in college prep early and using technology to create a supportive application process that encourages reflection and self-discovery.Students who sign up for the free platform get access to a digital “locker”, which they can use all through high school to save class papers, artwork, newspaper stories, videos and photos to share with colleges when they eventually apply.VIDEO — CHAT INTERVIEWSAt some schools, an interview with an admission officer is an important part of the application process. To make it easier, several virtual interviewing tools have popped up, such as a video-based platform from Kira. More than 140 universities worldwide use Kira's video assessment tool to conduct real-time interviews with prospective students. During the interview, candidates are shown the questions prerecorded by the particular school and must respond in real time by talking into the camera on their laptop or phone. In addition to showing their ability, to speak fluently in English and think on their feet, it helps admission officers determine the “motivation, commitment and drive” of applicants.UNIQUE SCHOOL TOOLSSome universities have come up with their own ways to allow students to show their skills and personalities. For example, the Massachusetts Institute of Technology, encourages applicants to display their technical abilities and creativity by submitting a “Maker Portfolio” —a written or videotaped description of a project that shows creative and problem-solving skills. While a new app would fit the bill, the project could be anything from an origami design to a potato cannon.(1)Which of the apps give students more guidance from their high school?A. ZEEMEE.B. THE COALITION LOCKER.C. VIDEO — CHAT INTERVIEWS.D. UNIQUE SCHOOL TOOLS.(2)What does the underlined word “it” in the fourth part of the passage refer to?A. The video interview.B. The description.C. The application.D. The student's ability.(3)What is the common feature required by colleges and universities according to the passage?A. Creativity.B. Braveness.C. Willingness to share.D. Technical ability.【答案】(1)B(2)C(3)A【解析】【分析】本文是一篇说明文,在今天的Facebook、Instagram和微信的世界里,照片、视频和手机盛行的同时,一些新工具让大学申请者更容易使用技术来展示他们的个性、技能和创造力。

【英语】高三英语阅读理解题20套(带答案)含解析一、高中英语阅读理解1.阅读理解Scientists have discovered a "monster black hole" so massive that, in theory, it shouldn't exist. It's a stellar black hole—the type that forms after stars die, collapse, and explode. Researchers had previously believed that the size limit was no more than 20 times the mass of our sun because 8S these stars die, they lose most of their mass through explosions that expel matter and gas swept away by stellar windsThis theory has now been toppled by LB-1, the newly discovered black hole. Located about 15.000 light years away, it has a mass 70 times greater than our sun, according to a press release from the Chinese Academy of Sciences.The findings were published by Chinese researchers in the journal Nature on Wednesday."Black boles of such mass should not even exist in our galaxy, according to most of the current models of stellar evolution," said Liu Jifeng, head of the team that made the discovery. "LB-1 is twice as massive as what we thought possible. Now theorists will have to take up the challenge of explaining its formation."Scientists are now scratching their heads at how LB-1 got so huge.The Chinese team has proposed a number of theories. LB-1' sheer size suggests that it "was not formed from the collapse of only one star," the study said— instead, it could potentially be two smaller black holes orbiting each other.Another possibility is that it formed from "fallback supermova." This is when a supernoma—the last stage of an exploding star—ejects material during the explosion, which then falls back into the supernova, creating a black hole.This fallback formation is theoretically possible but scientists have never been able to prove or observe it. If this is how LB-1 formed, then we may have "direct evidence for this process" for the first time, the study said.There are several types of black holes and stellar black holes like LB-1 are on the smaller side, according to NASA. Supermassive black holes are much bigger—they can be billions of times the mass of our sun,Scientists believe supermassive black holes may be connected to the formation of galaxies, as they often exist at the center of the mass star stems but it is still not clear exactly how, or which form first.(1)Why does the writer write the article?A.To report the great achievement Chinese scientists have made in black hole theory,B.To inform the readers of the basic knowledge about the black hole,C.To share with the readers the new development of the black hole discovery,D.To demonstrate the significance of discovering new black holes for science.(2)Which of the following about LB-1 is true to the passage?A.It is the biggest black hole ever discovered.B.It lost only a small part of its mass through explosion.C.It couldn't have been formed from the collapse of one star.D.Its discovery may lead to some breakthrough in the "fallback formation theory".(3)Which of the following is right according to the passage?A.If the sun in our galaxy dies some of its mass will be taken away by stellar winds.B.A massive supernova will be formed and then exploded if the sun in our galaxy dies.C."The Milky Way" was formed after a supermassive black hole collapsed and exploded.D.If "the Milky Way" dies, a supermassive black hole will be formed after its death.【答案】(1)C(2)D(3)A【解析】【分析】本文是一篇新闻报道,报道了科学家们已经发现了一个“巨型黑洞”,其质量之大,在理论上是不应该存在。
