1.Some people think they have an answer to the troubles of automobile crowding and dirty air in large cities. Their answer is the bicycle, or "bike".
In a great many cities, hundreds of people ride bicycles to work every day. In New York City, some bike riders have even formed a group called Bike for a Better City. They claim that if more people rode bicycles to work there would be fewer automobiles in the downtown section of the city and therefore less dirty air from car engines.
For several years this group has been trying to get the city government to help bike riders. For example, they want the city to draw bicycle lanes on some of the main streets, because when bike riders have to use the same lanes as cars, there are accidents. Bike for a Better City feels that if there were special lanes more people would use bikes.
But no bicycle lanes have been drawn. Not everyone thinks it is a good idea--they say it will slow traffic. Some store owners on the main streets say that if there is less traffic, they will have less business. And most people live too far from downtown to travel by bike.
The city government has not yet decided what to do.It wants to keep everyone happy. Only on weekends, Central Park is closed to cars, and the roads may be used by bicycles only. But Bike for a Better City says that this is not enough and keeps fighting to get bicycle lanes downtown.(260 words)
2.What are some good time management strategies?
From MalcSimmond's answer——
The best method for time management I have ever found is Getting Things Done – GTD.
However, many people are enthusiastic when they read the book of Getting Things Done but fail to follow through. This is because it's an interesting combination of enlightening guidelines - as well as confusing ones!
Anyway, after four tries - over several years - I finally managed to apply it satisfactorily! And what made the difference for me was learning to use Evernote to apply the Getting Things Done system.
The basics of Getting Things Done are
- Keep a clear desk and workspace
- If you don't do a task immediately, then write it down – always
- Once written down, prioritize your tasks (this is done easily with Evernote)
- Choose a task to do
- Carry out daily, and weekly reviews
Daily Review–check your diary, emails, and today is to dos, as often as necessary for you to feel comfortable everything is under control.
Weekly Review – this is the bigger maintenance job. Check through all your to dos. Delete any which you have done, change the priority of tasks as appropriate for you, check each project you have (I recommend a tag per project, in Evernote), there are a few other little maintenance tasks which are done at this time, but I won't go into those here.
So that's it. Getting Things Done is the best time management system I have ever come across. And the only way I have found of applying it consistently, and effectively, and pleasurably, is by using Evernote.
Evernote also has the advantage of being extremely easy to add data to. It is on all devices, major browsers have a "clipper" to send webpages and URLs to Evernote, you can forward emails straight into your Evernote, many tablet apps will send information directly to Evernote, et cetera.
All in all, it's a great system that really works.(332 words)
3.I was young and free and my imagination had no limits,I dreamed of changing the world.
As I grew older and wiser, I discovered the world would not change, so I shortened my sights somewhat and decided to change only my country. But it, too, seemed immovable.
As I grewinto my twilight years, in one last desperate attempt, I settled for changing only my family, those closest to me, but alas, they would have none of it.
And now, as I lie on my death bed, I suddenly realize:
If I had only changed myself first, then by example I would have changed my family.From their inspiration and encouragement, I would then have been able to better my country,and who knows, I may have even changed the world.(133 word)
4.Healthy life style involves keeping a balanced diet，living a routine life and undertaking regular physical exercises. A balanced diet means eating a variety of foods and allowing for an adequate intake of them every day. Living a routine life refers to getting up and going to bed at a fixed time, and maintaining 8-hour sleep each day. Doing physical exercisesregularly is also the key to staying healthy. Choose a suitable type of exercise depending on your own interests and physical conditions and keep to it.
Unhealthy life style includes smoking, drinking and overeating. Smoking would cause bronchitis and lung cancer. According to a recent survey, four million people die each year from diseases linked to smoking. Drinking would result in health and social problems. Drunk driving is a deadly hazard both to the person himself and to other people. Overeating would lead to obesity, diabetes, and other health-related diseases.
It has been an undisputable fact that good life style will make people healthy, and bad one will result in many diseases. To keep fit, we should develop good living habits, i.e. , eating a balanced diet, living a routine life, and doing physical exercises regularly.(199 words)
5.If you thought running was just great for the body, then think again. Scientists have uncovered evidence the sport not only keeps people trim but also boosts brain power.
The research found that people who keep fit are more likely to have larger brains, better memories and clearer thinking.They also found that unfit people tended to have smaller brains and reduced cognitive skills.
The findings add to a growing body of evidence which links exercise with helping protect the brain against ageing and also aiding it to replace dying cells. This might reduce the risk of debilitating illnesses and diseases such as Alzheimer's. One research paper within its latest issue sees scientists at Kentucky University putting 30 adults aged 59-69 on a treadmill. Their heart and lung capacity was measured and an MRI scanner was used to assess the blood flow to their brains. Those who were less fit had smaller brains compared to the fitter volunteers who had larger brains.
Scientists in Germany followed 21 adults aged between 60-77. As they went through a three-month fitness program they saw improvements in their memory. Researchers are not yet sure why exercise helps to protect brain cells but some research in mice has produced results. Mice, examined at the National Institute on Aging, in Baltimore, found that cells in the hippocampus, an area of the brain used for memory, were actively reproducing while their fatter peers were in decline.
Linda Clare, professor of clinical psychology of ageing and dementia at Exeter University
and a member of the Global Council on Brain Health told The Sunday Times: 'Moderate-intensity aerobic activity such as brisk walking, cycling or running can produce changes in brain structure and function.'(285 words)
6.In the past, grammar was the focus of the English language teaching and learning in China. The English class had been dominated by teachers‘ explaining grammar rules and sentence structures. Students were busy taking notes and they were given no time to practice using English for communication. Consequently, while having acquired a sufficient amount of grammar knowledge, students did not know how to express themselves in simple English.
In recent years, it has been argued that we should stop teaching grammar in class, as memorizing grammar rules is not the proper way to learn English. It is suggested that more emphasis should be laid on developing students‘ communicative abilities, i.e. their abilities to use English to interact with people. As a result, cla ss time is mainly distributed to students‘ doing various types of communicative tasks.
However, more and more people have come to realize that grammar is necessary in developing communicative skills. Both fluency and accuracy are important in language learning. The key now is how to combine the two in practice.(173 words)
7.Most Chinese students have difficulties in learning English. The difficulties vary so much from person to person that it is difficult to cite here in a few words. Some may have problems in reading. Others may have trouble in writing. I also had problems in English learning, but my difficulty seemed to lie in listening. For example, when tested for listening comprehension, I couldn't understand a single sentence, let alone a passage of medium level.
In order to overcome the difficulty in my English learning, I made great efforts to find the key to the problem. I consulted my teacher and found out that I merely didn't have enough time to practice listening. So I bought a tape recorder and listened to it at least two hours a day. Inaddition, I listened to "Special English" on VOA. I also went out of my way to speak to foreigners on the campus whenever we meet so that I could have the chance to listen to the native speakers. After half a year's hard work, I could get 70% of the questions correct in listening comprehension tests.
I own my success to my English teacher. It is him who tells me the correct way to learn English. It is him who always encourages me when I encounter difficulties and feel disappointed.(221 words)
8.For years, studies have found that first-generation college student – those who do not have a parent with a college degree –lag other students on a range of education achievement factors. Their grades are lower than and their dropout rates are higher. But since such students are most likely to advance economically if they succeed in higher education, colleges and universities have pushed for decades to recruit more of them. This has created ―a paradox‖ in that recruiting first-generation student, but then watching many of them fail, means that higher education has ―continued to reproduce and widen, rather than close.‖ An achievement gap based on social class, according to the depressing beginning of a paper forthcoming in the journal Psychological Science.
But the article is actually quite optimistic, as it outlines a potential solution to this problem, suggesting that an approach (which involves a one-hour, next-to-no-cost program) can close 63 percent of the achievement gap (measured by such factors as grades) between first-generation and other students.
The authors of the paper are from different universities, and their findings are based on a study involving 147 students (who completed the project) at an unnamed private university. First generation was defined as not having parent with four-year college degree. Most of the first-generation students (59.1 percent) were recipients of Pell Grants, a federal grant of undergraduates with financial need, while this was true only for 8.6 percent of the students with at least one parent with four-year degree.
Their thesis – that a relatively modest intervention could have a big impact – was based on the view that first-generation students may be most lacking not in potential but in practical knowledge about how to deal with the issues that face most college students. They cite past research by several authors to show that this is the gap that must be narrowed to close the achievement gap.
Many first-generation students ―struggled to navigate the middle-class culture of higher education, learn the ?rules of the game,‘ and take advantage of college resources,‖ they write. And this becomes more of a problem when colleges don‘t talk about the class advantages and disadvantages of different groups of students. Because US colleges and universities seldom acknowledge how social class can affect students‘ educational experiences, many first-generation students lack of sight about why they are struggling and do not understand students ?like them‘ can improve.‖ (395 words)
9.There are two factors which determine an individual's intelligence. The first is the sort of brain he is born with. Human brains differ considerably, some being more capable than others. But no matter how good a brain he has to begin with, an individual will have a low order of intelligence unless he has opportunities to learn. So the second factor is what happens to the individual— the sort of environment in which he is brought up. If an individual is handicapped(不利) environmentally, it is likely that his brain will fail to develop and he will never attain the level of intelligence of which he is capable.
The importance of environment in determining an individual's intelligence can be demonstrated by the case history of the identical twins, Peter and Mark. Being identical, the twins had identical brains at birth, and their growth processes were the same. When the twins were three months old, their parents died, and they were placed in separate foster homes. Peter was raised by parents of low intelligence in an isolated community with poor educational opportunities. Mark was reared in the home of well-to-do parents who had been to college. He was read to as a child, sent to good schools, and given every opportunity to be stimulated intellectually. This environmental difference continued until the twins were in their late teens, when they were given tests to measure their intelligence. Mark's I. Q. was 125, twenty-five points higher than the average and fully forty points higher than his identical brother. Given equal opportunities, the twins, having identical brains, would have tested at roughly the same level.(274 words)
10.The Advantages and Disadvantages of Living in the 21st century
Living in the 21st century offers certain advantages,such as a higher standard of living, but it also has some disadvantages, such as a polluted environment.
To begin with, most people now have more money for less hard work. They earn higher salaries than before and enjoy better social security, such as social welfare for laid-off workers and disability insurance.
Secondly, because of the advance in medical technology which leads to better medical care and treatment, people‘s life expectancy is longer. Moreover, most people now can afford to buy foods of high nutrition and enjoy their leisure time.
Thirdly, modern conveniences such as radio, TV, internet, various vehicles and labour-saving machines in the home, all greatly facilitate human communication, transportation and housework as well.
Nevertheless, living in the 21st century also has its disadvantages. The most serious one is the increasingly polluted environment; air is filled with smog and water is contaminated by chemicals from factories.Another main disadvantage is the personalization of human relationships which mostly result from people‘s ever-increasing contact with machines and numbers. Still one more disadvantage is the weakening of spiritual values. An undeniable fact is that a large number of people are solely interested in materialistic culture,while neglecting spiritual civilization. Limited by space, we have to skip the examples.
In conclusion, although the 21st century has indeed given us a lot of advantages, it may not have made us wiser, because it has also made our earth dirtier, our people less humane, and our spiritual life poorer, We should continue to enjoy the benefits of technological advancement,however, we mustmake a concerted effort to preserve our natural environment for future generations. Moreover, we should take the time now to make our lives more meaningful in an increasingly impersonal, computerized world.(308 words)
A “You can use me as a last resort（选择）, and if nobody else volunteers，then I will do it.” This was an actual reply from a parent after I put out a request for volunteers for my kids lacrosse（长曲棍球）club. I guess that there's probably some demanding work schedule, or social anxiety around stepping up to help for an unknown sport. She may just need a little persuading. So I try again and tug at the heartstrings. I mention the single parent with four kids running the show and I talk about the dad coaching a team that his kids aren’t even on … At this point the unwilling parent speaks up,“Alright. Yes, I’ll do it.” I’m secretly relieved because I know there’s real power in sharing volunteer responsibilities among many. The unwilling parent organizes the meal schedule, sends out emails, and collects money for end-of-season gifts. Somewhere along the way, the same parent ends up becoming an invaluable member of the team. The coach is able to focus on the kids while the other parents are relieved to be off the hook for another season. Handing out sliced oranges to bloodthirsty kids can be as exciting as watching your own kid score a goal. Still, most of us volunteers breathe a sigh of relief when the season comes to a close. That relief is coupled with a deep understanding of why the same people keep coming back for more: Connecting to the community（社区）as you freely give your time, money, skills, or services

(2) Dear Sir, I am writing about your January bill, which I am returning with this letter. I am not going to pay this bill. Last month I bought a table and four chairs for $65.50. They were sent to me on December 18. That night one leg of the table broke while my wife was putting our dinner on it. It fell on one of the chair, and that broke, too. Our $ 2.50 steak(牛排) landed on the floor, and the dog ate it. I spoke to the salesmen who had sold me the table and the chairs. He told me to write you a letter. I wrote you on December 20, saying that I was not going to pay for the furniture. On December 21 some men came and took it back to the store. Please do something about your records. I do not want to receive another bill for the furniture which I returned. Yours truly
6 It’s important to learn about protecting our environment. Here is a 5R rule for us: 1. Reduce If you want to reduce waste, you should use things wisely (明智地). A large number of trees are being cut down to make paper. If everyone uses a little paper carelessly and throw it out, soon we would not have any trees left. Other things are also being wasted, and people don’t know what to do with the waste in big cities. So it is necessary to reduce the waste. 2.Reuse You should always think of reusing the usable things before throwing them out. Give your clothes you do not use or the ones which too small to the poor. In a family, you may pass on such clothes to younger brothers or sisters. 3.Recycle Bottles, cans (罐子) and paper can easily be recycled. By doing so we save lots of time and money. For example, coke cans are sent to a factory, where they are smashed flat (压平) and melted (融化) and the metal things are made for new coke cans. 4.Recover When you buy a box of apples, there may be few rotten (腐烂的) apples, you have two choices: one is to throw the whole apples away, or you could cut off the rotten parts and use the good parts. In this way, you are recovering the eatable parts of food. 5.Repair If one of the begs of your table is broken, you can repair it. If you want to change for better ones, it is better for you to sell the old things or give them to other people who can use them after doing some repair. It is true that North America is a “throw-away”society, but the time has come to change our way of life so that we can protect our environment. Every one of us should try our best. 1.The “Reduce”rule mainly requires (要求) us _______. A. to use things wisely B. to cut down many trees C. to use a lot of paper D. to throw away your old clothes 2.What’s the right order (顺序) of recycling coke cans? a. collect the used cans b. melt them c. smash them flat d. send them to a factory A. a b c d B. a d c b C. d b c a D. c a b d 3.The “Recover”rule mainly requires us _______. A. to throw waste things away B. to cover waste things with earth C. to get back the useful parts D. to throw the whole things away 5.Which is the best way to do with your broken tables? A. Throwing them away. B. Requiring them. C. Selling them. D. Putting them away. 7 To: President Bush, the White House From: Saddam Hussein, in Baghdad Dear President Bush, Well, you sure ruined (毁掉) my birthday…. OK, you won, and your prize is Iraq. Are you

2019年中考英语阅读理解基础练（二） 【实战训练】 A （2019中考教育类选练） Jack thought himself a basketball fan. He watched quite a lot of American NBA basketball games. Not only did he watch them, he spent much of his free time playing on the court too. Then came the final year of his middle school. All of his regular teammates stopped showing up on the court because they were simply too busy preparing for the high school entrance exam to play. He was, of course, under much stress himself, like everyone else. A good exam result meant a good high school; a mediocre(平庸的)score meant a mediocre school. Much was at stake. However, he loved basketball so much that he still found time to play, this time with a group of guys who were said to have skipped classes(逃课)before. Some of his teachers started worrying about him. They asked his mother to go to school to let her know that Jack was hanging out with problem kids. When his mother returned home that day, she wanted to talk to Jack. Knowing the purpose of her visit to the school, Jack thought his mother would punish him for befriending（以朋友方式对待）those bad guys. To his surprise, his mother was not angry with him at all. She wanted to hear her son's side of the story. So Jack told his mother about what he knew of Simon and Peter. Simon's parents were badly ill; Peter's father had lost his job. They both seemed to Jack to be normal kids. Jack's mother thought for a moment, then went on to say that she was OK with her son playing with them and that she and her son should think of ways to help these kids. Soon Jack's mum introduced some part-time jobs to Simon and Peter, which th ey accepted. She believed in her son and cared about those who were less lucky. Jack's basketball friends and he have left for different places, but they still keep in touch. He knows Peter is now a manager of a local bank. Simon is currently a freshman at a university. Sadly, it is impossible to get together to play basketball again, bu t whenever they get on the phone, they talk about it all the time. （）1. After Jack's mother came home from school, she .

2014高考英语阅读理解全程基础训练（21）及答案 阅读理解-------B Imagine putting a seed in a freezer, waiting 30,000 years, and then taking the seed out and planting it. Do you think a flower would grow? Amazingly, scientists have just managed to do something very similar. They found the fruit of an ancient plant that had been frozen underground in Siberia —a region covering central and eastern Russia — for about 31,800 years. Using pieces of the fruit, the scientists grew plants in a lab. The new blooms have delicate white petals. They are also the oldest flowering plants that researchers have ever revived from a deep freeze. “This is like regenerating a dinosaur from tissues of an ancient egg,” said University of California, Los Angeles biologist Jane Shen-Miller. The plant has a long history. Back when mammoths and woolly rhinoceroses walked the land, an Arctic ground squirrel buried seeds and fruits in an underground chamber near the Kolyma River in northeastern Siberia. The ground became permafrost, a layer of soil that stays frozen for a long time. Recently, Russian scientists dug out the old squirrel hole and found the plant remains 38 meters below the surface. Back at the lab, the team fed nutrients to tissue from three of the fruits to grow shoots. Then the scientists transferred the shoots to pots filled with soil. The plants produced seeds that could be used to grow even more of them. It’s important for scientists to know that plant tissues can still be revived after being frozen for a long time. That’s because many researchers are trying to preserve the seeds of modern plants by freezing them and then storing them in giant lockers at various spots around the globe. One such endeavor, an underground facility in Norway, is called the Svalbard Global Seed Vault. It stores hundreds of thousands of frozen seeds. If a plant ever goes extinct, scientists could bring it back by taking its seeds from the Svalbard or other storage lockers. “No one knows how long they are able to live for, but freezing is basically the
高中英语阅读理解30篇 1、To be a good teacher, you need some of the gifts of a good actor; you must be able to hold the attention and interest of your audience; you must be a clear speaker, with a good, strong, pleasing voice which is fully under your control; and you must be able to act what you are teaching, in order to make its meaning clear. Watch a good teacher, and you will see that he does not sit still before his class：he stands the whole time he is teaching; he walks about, using his arms, hands and fingers to help him in his explanations, and his face to express feelings. Listen to him, and you will hear the loudness, the quality (音色) and the musical note of his voice always changing according to what he is talking about. The fact that a good teacher has some of the gifts of a good actor doesn’t mean that he will indeed be able to act well on the stage, for there are very important differences between the teacher’s work and the actor’s. The actor has to speak words which he has learnt by heart; he has to repeat exactly the same words each time he plays a certain part, even his movements and the ways in which he uses his voice are usually fixed beforehand (预先). What he has to do is to make all these carefully learnt words and actions seem natural on the stage. A good teacher works in quite a different way. His audience takes an active part in his play：they ask and answer questions, they obey orders, and if they don’t understand something, they say so. The teacher therefore has to meet the needs of his audience, which is his class. He cannot learn his part by heart, but must invent it as he goes along.
