The world itself is becoming much smaller by using modern traffic and modern communication means. Life today is much easier than it was hundreds of years ago, but it has brought new problems. One of the biggest problems is pollution. To pollute means to make things dirty. Pollution comes in many ways. We see it, smell it, drink it and even hear it.
Man has been polluting the earth. The more people, the more pollution. Many years ago, the problem was not so serious because there were not so many people. When the land was used up or the river was dirty in one place, man moved to another place. But this is no longer true.
Man is now slowly polluting the whole world.
Air pollution is still the most serious. It’s bad for all living things in the world, but it is not the only one kind of pollution. Water pollution kills our fish and pollutes our drinking water. Noise pollution makes us angry more easily.
Many countries are making rules to fight pollution. They stop people from burning coal in houses and factories in the city, and from putting dirty smoke into the air. Pollution by SO2 is now the most dangerous kind of air pollution. It is caused by heavy traffic. We are sure that if there are fewer people driving, there will be less air pollution.
The earth is our home. We must take care of it. That means keeping the land, water and air clean. And we must take care of the rise in pollution at the same time._______, our world is becoming much smaller.
A.Because of the rise in pollution |
B.Thanks to science development |
C.Because the earth is being polluted day and night |
D.Because the earth is blown away by the wind every year |
Hundreds of years ago, life was __________ it is today.
A.much easier than | B.as easy as |
C.much harder than | D.as hard as |
Pollution comes in many ways. We can even hear it. Here “it” means _______.

C.air pollution | D.water pollution |
Air pollution is the most serious kind of pollution because _______.
A.it makes much noise |

Which of the following is NOT true?
A.Many countries are making rules to fight pollution. |
B.The pollution of the earth grows as fast as the world population does. |
C.The problem of pollution is not so serious because there are not so many people living on the earth. |
D.If people could go to work by bus or bike instead of car or motorbike, it would be helpful in fighting against the problem of SO2. |
One of my wonderful memories is about a Christmas gift. Unlike other gifts, it came without wrap(包装).
On September 11th, 1958, Mum gave birth to Richard. After she brought him home from hospital, she put him in my lap, saying. “I promised you a gift, and here it is.” What an honour! I turned four a month earlier and none of my friends had such a baby doll of their own. I played with it day and night. I sang to it. I told it stories. I told it over and over how much I loved it!
One morning, however, I found its bed empty. My doll was gone! I cried for it. Mum wept and told me that the poor little thing had been sent to a hospital. It had a fever. For several days, I heard Mum and Dad whispering such words as “hopeless”, “pitiful”, and “dying”, which sounded ominous.
Christmas was coming. “Don’t expect any presents this year,” Dad said, pointing at the socks I hung in the living room. “If your baby brother lives, that’ll be Christmas enough.” As he spoke, his eyes filled with tears. I’d never seen him cry before.
The phone rang early on Christmas morning. Dad jumped out of bed to answer it. From my bedroom I heard him say, “What? He’s all right?” he hung up and shouted upstairs. “The hospital said we can bring Richard home!”
“Thank God.” I heard Mum cry.
From the upstairs window, I watched my parents rush out to the car. I had never seen them so happy. And I was also full of joy. What a wonderful day! My baby doll would be home. I ran downstairs. My socks still hung there flat. But I knew they were not empty; they were filled with love!What happened to the author on September 11th, 1958?

In his 1930 essay “Economic Possibilities for Our Grandchildren”, John Keynes, a famous economist, wrote that human needs fall into two classes: absolute needs, which are independent of what others have, and relative needs, which make us feel superior to our fellows. He thought that although relative needs may indeed be insatiable(无止境的), this is not true of absolute needs.
Keynes was surely correct that only a small part of total spending is decided by the desire for superiority. He was greatly mistaken, however, in seeing this desire as the only source of insatiable demands.
Decisions to spend are also driven by ideas of quality which can influence the demand for almost all goods, including even basic goods like food. When a couple goes out for an anniversary dinner, for example, the thought of feeling superior to others probably never comes to them. Their goal is to share a special meal that stands out from other meals.
There are no obvious limits to the escalation of demands for quality. For example, Porsche, a famous car producer, has a model which was considered perhaps the best sports car on the market. Priced at over $120,000, it handles perfectly well and has great speed acceleration. But in 2004, the producer introduced some changes which made the model slightly better in handling acceleration. People who really care about cars find these small improvements exciting. To get them, however, they must pay almost four times the price.
By placing the desire to be superior to others at the heart of his description of insatiable demands, Keynes actually reduced such demands. However, the desire for higher quality has no natural limits.According to the passage, John Keynes believed that .
A.desire is the root of both absolute and relative needs |
B.absolute needs come from our sense of superiority |
C.relative needs alone lead to insatiable demands |
D.absolute needs are stronger than relative needs |
What do we know about the couple in Paragraph 3?
A.They want to show their superiority. |
B.They find specialty important to meals. |
C.Their demands for food are not easily satisfied. |
D.Their choice of dinner is related to ideas of quality |
What does the underlined word “escalation” in Paragraph 4 probably mean?
A.Understanding | B.Increase |
C.Difference | D.Study |
The author of the passage mainly argues that .
A.absolute needs have no limits |
B.demands for quality are not insatiable |
C.human desires influence ideas of quality |
D.relative needs decide most of our spending |
With only about 1,000 pandas left in the world, China is desperately trying to clone(克隆)the animal and save the endangered species. That’s a move similar to what a Texas A & M University researchers have been undertaking for the past five years in a project called “Noah’s Ark”. Noah’s Ark is aimed at collecting eggs, embryos(胚胎), semen and DNA of endangered animals and storing them in liquid nitrogen. If certain species should become extinct, Dr. Duane Kraemer, a professor in Texas A & M’s College of Veterinary Medicine, said there would be enough of the basic building blocks to reintroduce the species in the future.
It is estimated that as many as 2,000 species of mammals, birds and reptiles will become extinct in over 100 years.
The panda, native only to China, is in danger of becoming extinct in the next 25 years.
This week, Chinese scientists said they grew an embryo by introducing cells from a dead female panda into the egg cells of a Japanese white rabbit. They are now trying to implant the embryo into a host animal. The entire procedure could take from three to five years to complete.
“The nuclear transfer(核子移植)of one species to another is not easy, and the lack of available panda eggs could be a major problem,” Kraemer believed. “They will probably have to do several hundred transfers to result in one pregnancy. It takes a long time and it’s difficult, but this could be ground-breaking science if it works. They are certainly not putting any live pandas at risk, so it is worth the effort,” added Kraemer, who is one of the leaders of the project at Texas A & M, the first-ever attempt at cloning a dog. “They are trying to do something that has never been done, and this is very similar to our work in Noah’s Ark. We’re both trying to save animals that face extinction. I certainly appreciate their effort and there’s a lot we can learn from what they are attempting to do. It’s a research that is very much needed.” The aim of “Noah’s Ark” project is to .
A.make efforts to clone the endangered pandas |
B.save endangered animals from dying out |
C.collect DNA of endangered animals to study |
D.transfer the nuclear of one animal to another |
According to Professor Kraemer, the major problem in cloning pandas would be the lack of .
A.available | B.host animals |
C.qualified researchers | D.enough money |
The best title for the passage may be .
A.China’s Success in Pandas Cloning |
B.The First Cloned Panda in the World |
C.Exploring the Possibility to Clone Pandas |
D.China- the Native Place of Pandas Forever |
From the passage we know that .
A.Kraemer and his team have succeeded in cloning a dog |
B.scientists try to implant a panda’s egg into a rabbit |
C.Kraemer will work with Chinese scientists in clone researchers |
D.about two thousand species will probably die out in a century |
Americans gave nearly $300 billion away last year. Do you know the reason? Beyond the noble goals of helping others, it is that giving will make them happier.
It is a fact that givers are happier people than non-givers. According to the Social Capital Community Benchmark Survey, a survey of 30,000 American households, people who give money to charity are 43% more likely than non-givers to say they are “very happy” about their lives. Similarly, volunteers are 42% more likely to be very happy then non-volunteers.
The happiness difference between givers and non-givers is not due to differences in their personal characteristics, such as income or religion. Imagine two people who are identical in terms of income and faith, as well as age, education, politics, sex, and family circumstances, but one donates money and volunteers, while the other does not. The giver will be, on average, over 40 percentage points more likely to be very happy than the non-givers.
A number of studies have researched exactly why charity leads to happiness. The surprising conclusion is that giving affects our brain chemistry. For example, people who give often report feelings of euphoria, which psychologists have referred to as the “Helper’s High”. They believe that charitable activity produces a very mild version of the sensations people get from drugs like morphine and heroin.
Of course, not only does giving increase our happiness, but also our happiness increases the possibility that we will give. Everyone prefers to give more when they are happy. Researchers have investigated this by conducting experiments in which people are asked about their happiness before and after they participate in a charitable activity, such as volunteering to help children or serving meals to the poor. The result is clear that giving has a strong, positive causal impact on our happiness, so does happiness on givingAccording to Paragraph 2. We can learn that .
A.only those people who gave money to charity will be happy |
B.more givers say they feel having happy lives than non-givers |
C.those who donate money are happier than those who volunteer |
D.42% of the volunteers say they are as happy as the non-volunteers |
What causes the happiness difference?
A.Income. | B.Faith. | C.Education. | D.Donation. |
The underlined word “euphoria” in Paragraph 4 is closest in meaning to .
A.relaxation | B.uncertainty |
C.nervousness | D.pleasure |
If a person feels happy, he may .
A.ask for more donations | B.stop charitable activity |
C.be likely to give more | D.cook food for the poor |
Which of the following is the main theme of this passage?
A.Giving brings happiness. | B.Americans love donating. |
C.The happiness difference. | D.Feelings of volunteers. |
Finding a friend doesn’t seem like a difficult job. However, bad friends are easier to find than good friends these days. If you’re sitting there and wondering if you have a bad friend, let me define it for you.
A bad friend is someone whose jealousies and insecurities outweigh their love for someone. They night want to be a good friend but they’re too messed up in their own head to ever actually do it. They wonder if their friends are going out without them or if they’re being forgotten and left behind. People who are violently insecure don’t have what it takes to be the quality of a friend.
Bad friends are narcissistic(自恋的). They look for any opportunity to bring the conversation back to them. Worse, they might not even be aware that they’re doing it. In their mind, they might think they are the best friend ever, which is truly frightening.
Bad friends are quick-change. They’re by your side when you’re fun and you have something to give them but as soon as you’re going through a difficult time, they will become indifferent quickly. They won’t bring you cold medicine. They won’t give you a ride to the doctor, everything they do is self-serving.
If you find a friend who has these same characteristics, send them to your bad friend list immediately. Your friends are supposed to be the solution to your problems, not the source.
I believe your twenties are a time when you need positive and helpful friends. In such a time, friendships aren’t easy to maintain like they once were in school. Now we actually have to put work into it, we have to make a conscious effort to keep the friendship going. You need to ask yourself, “Is this person worth it? Do they treat me like a fool or what?” if your have doubts, try to make them clear by considering the past experiences. Toxic(有毒的) friendships do nothing but drag you down. My point is that you have to take care of yourself and stop getting in touch with your bad friends. Only surround yourself with people who bring out the best qualities in you. It may sound cruel but it’s true,.The author believes that we can easily find a .
A.close friend | B.poor friend | C.good friend | D.bad friend |
Bad friends give the author the following impressions EXCEPT being .
A.outgoing | B.insecure |
C.narcissistic | D.self-centred |
We can infer from the passage that a bad friend will when you have trouble.
A.feel worried as you do | B.try hard to help you out |
C.do nothing but leave you | D.pay more attention to you |
In the last paragraph, you are advised .
A.not to treat your friends like fools | B.not to keep a terrible friendship |
C.not to be a bad friend of others | D.not to doubt but ask yourself |
What is the purpose of the passage?
A.To tell us finding a friend is not an easy job for everyone. |
B.To help us know about bad friends and get rid of them. |
C.To encourage us to make more friends in school. |
D.To advise us not to treat our close friends badly. |
