1 . Naturally, American schoolchildren love holidays. And they get a lot of them each year. Besides having national holidays such as Thanksgiving and Presidents’ Day off from school, students get longer breaks in the spring and during the summer holidays. In fact, kids in the US only go to school for about 180 days a year. To students, holidays are perfect. However, parents think there are advantages and disadvantages.
On the one hand, school holidays allow families to spend time together. Many American parents take time off from work during June, July or August to travel with their children on vacations either in the US or in a foreign country. On the other hand, schoolchildren get much more time off school than parents get vacation time. This means that parents with young children may have to pay more in babysitting or daycare costs. As well, the long summer holidays mean that students sometimes get bored.
Besides going on trips with their parents, American students enjoy taking part in different kinds of activities during the holidays. For example, some kids enjoy summer camps and outdoor adventure holidays. Such trips are great for adventurous students. They also have a lot to offer students who aren’t usually interested in traditional PE activities. You can do courses in survival skills, for example. Students learn how to make a camp in the forest, which wild food they can eat and how to find their way back to the center.
Students who are not excited about summer camps and outdoor adventure may take part in courses in computer game design, filmmaking and photography during the holidays. Finally, the traditional school trip to foreign countries is always popular. Students can practice their foreign language skills and experience everyday life in a different culture.

2 . In my everyday life, I am on an ongoing journey to figure out different ways to reduce my carbon footprint on the planet. A carbon footprint is the measure of influence our activities have on the environment, in particular climate change. It is calculated by the amount of greenhouse gas we produce in our daily lives. Fortunately, nowadays it is much easier to make eco-friendly lifestyle choices than, let's say, 20 years ago. But one question has been on my mind a lot lately: is it better to buy new eco-friendly products or used traditionally produced goods?
After doing some research, I have decided that some things are better new and others are better used. Let me try to explain.
A carbon footprint is made up of two parts, the primary footprint and the secondary footprint. The primary footprint is a measure of our direct emissions(排放)of carbon dioxide(CO2)from the burning of fuels, including household energy consumption and transportation. The secondary footprint is a measure of the indirect CO2 emissions from the whole lifecycle of products we use-those related to their production and breakdown.
Based on this understanding, we have a good deal of control and responsibility over our carbon footprint. Things like dishes, clothes and furniture fall into the “secondary footprint” group, so less is more and we can focus on finding used goods to avoid the added production. However, for the car and the other appliances(设备)that we need we can go with new, energy-saving models. I heard somewhere that electronics and appliances give off 90% of their carbon footprint after they leave the factory. So it seems most reasonable to go for the energy-saving models. The main concern here is the amount of energy that goes into the making of new products and whether or not that extra carbon is worth the footprint the product will make once it gets to you.
1. What is the text mainly about?| A．What appliances to buy to save energy. |
| B．What a carbon footprint means in our life. |
| C．How to identify different carbon footprints. |
| D．How to make eco-friendly lifestyle choices. |
| A．It is related to our consumption of fuels. |
| B．It is made when we are buying the products. |
| C．It is less harmful than the primary carbon footprint. |
| D．It is counted as ours though not directly made by us. |
| A．Using second-hand textbooks. | B．Using old and expensive cars. |
| C．Buying new but cheap clothes. | D．Buying new wooden furniture. |
| A．using the product | B．recycling the product |
| C．making the product | D．transporting the product |
3 . The traditional Chinese lunar calendar(农历）divides the year into 24 solar terms(节气）．Start of Winter, the 19th solar term of the year,begins this year on Nov 7 and ends on Nov 21.
Start of Winter is the first solar term of winter,which means winter is coming and crops harvested in autumn should he stored up.
In ancient times, the Start of Winter was regarded as the beginning of winter, however,due to geographical factors, the actual winter time varies from place to place.
In fact,the Start of Winter is not the beginning of winter in terms of meteorology(气象学）。The weather every year is different, so the beginning of winter could be quite different.And as China is very large, it starts at different times in different areas.
The beginnings of the four seasons were important festivals in ancient times. Before the Start of Winter,the ancient emperor would take a shower and have no more meat.On that day,the emperor would lead his officials to the countryside and"welcome the winter".
People eat dumplings on the beginning of winter. Legend has it that in the late Eastern Han Dynasty,Zhang Zhongjing invented "Jiao Ear"(娇耳）to treat typhoid(伤寒） patients with ear frostbite(冻疮）.He cooked mutton,hot peppers and herbs to drive out the cold and warm up the body.He put these materials into a dough skin and made them into an ear shape.Since then,people have learned to make the food which became known as "dumpling" or jiaozi. Today there is still a saying that goes "Eat dumplings on Start of Winter Day, or your ears will be frostbitten.”
1. Which of the following is right about Start of Winter?| A．It is one of the solar terns in Chinese calendar. |

4 . You might be the apple of your mother’s eye, which could only be a good thing. But adults who believe they are their mother's favorite child are at an increasing risk of depression, according to a study.
“It is a huge cost for those who think they get closest to their mothers, and these children report higher depressive symptoms（症状）,” said Professor Jill Suitor from Purdue University in Indiana, who led the study.
The academics used date collected from 725 adult children with an average age of 49, analyzing levels of emotional closeness, conflict, pride and disappointment.
The researchers added that previous studies had found that those who were closer to their mothers experienced less closeness with their siblings (兄弟姐妹).
Though few mothers or fathers would admit that they have a favorite son or daughter, studies have suggested they often do.
One such piece of research, which was carried out by the University of California in 2005, found that 65 percent of mothers and 70 percent of fathers showed a preference for one of their children over their siblings.
A previous study carried out by Professor Suitor and Dr Gilligan found that mothers tended to favor an adult child who was similar to them, in terms of values and beliefs.
Arabella Russell, a professor in Dorking, Surrey, said family problems, such as the siblings cannot get along well with each other, can often spill over into our romantic relationships, by influencing how we relate to our partners.

5 . Binge-watching (追剧) your favorite TV series is bad for your brain. Dr. Randall Wright, based in Texas, said the need to watch episode (集) after episode has a similar influence on the brain to gambling (赌博). What’s more, it often leads to social loneliness, snacking on junk food and a shortage of exercise and sleep, which, over time, is bad for the brain.
When you let auto play start the next episode, you can find out what happens next and your brain receives good feedback, Dr. Wright wrote in an article. This right-away satisfaction is similar to gambling where even after a win, you are not satisfied and want to continue playing. With binge-watching, you are not satisfied with stopping after episode five and want to continue watching. This cycle coupled with the snacking and the long time sitting can lead to unhealthy changes in your brain and body over time.
Dr. Wright said, “Binge-watching itself is not bad. It becomes problematic when you are watching a third, fourth or fifth episode instead of doing healthy activities.” But he said it is possible to avoid the bad influence of binge-watching with four tips, including staying away from salty, fatty, calorific foods, exercising before a binge-watching, setting an alarm for sleep and balancing TV viewing with socializing.
If you add these tips to your binge-watching practice, you can create lasting healthy habits and still enjoy the now-and-then binge-watching time without hurting your brain.

6 . Anyone who commutes(通勤)by car knows that traffic jams are an unavoidable part of life. But humans are not alone in facing potential backups.
Ants also commute—between their nest and sources of food. The survival of their habitats depends on doing this efficiently.
When humans commute, there’s a point at which cars become dense(稠密) enough to slow down the flow of traffic, causing jam. Researchers wanted to know if ants on the move could also get stuck. So they regulated traffic density by constructing bridges of various widths between a colony of Argentine ants and a source of food. Then they waited and watched, trying to find out at what point they are going to have a traffic jam.
But it appears that that never happened. They always managed to avoid traffic jam. The flow of ants did increase at the beginning as ants started to fill the bridge and then levelled off at high densities. But it never slowed down or stopped, even when the bridge was nearly filled with ants.
The researchers then took a closer look at how the behaviour of individual ants impacted traffic as a whole. And they found that when ants sense overcrowding, they adjust their speeds and avoid entering high-density areas, which prevents jams. These behaviors may be promoted by pheromones, chemicals that tell other ants where a trail is. The ants also manage to avoid colliding(碰撞) with each other at high densities, which could really slow them down.
Can ants help us solve our own traffic problems? Not likely. That’s because when it comes to getting from point A to point B as fast as possible, human drivers put their own goals first. Individual ants have to be more cooperative in order to feed the colony. But the research could be useful in improving traffic flow for self-driving cars, which can be designed to be less like selfish humans—and more like ants.

7 . The decision on Tuesday by Japan and the International Olympic Committee (IOC) to postpone the Tokyo 2020 Olympic Games until next summer because of the novel coronavirus pandemic must have been a hard one to make.
Although the Games have been canceled—three times in all, in 1916, 1940 and 1944—due to the two world wars in the modern Olympics’ history of more than 120 years, never before have any Games been postponed to a different year.
Nonetheless, the decision is the right one. If it is not brought under control, the harm done to human society by the pandemic could be more serious and far-reaching than even the two world wars. Given the number of countries affected and social and economic shock waves that have been caused by the rapid spread of the virus, postponing the Games is the only right and sensible choice to make.
After all, nothing is more important than people’s lives. Postponing the Games not only safeguards the health of athletes, audiences and everyone involved in the Games, but also reduces potential transmission of the virus from one place to another. Even looking at it from only a sporting level, the pandemic has already caused huge disruptions to athletes’ training and the qualification process.
It is undoubtedly a big blow for Japan, which has prepared meticulously for the largest sports event in the world, including renovating and upgrading its infrastructure and sports venues, such as rebuilding Tokyo’s Olympic Stadium at cost of $1.45 billion. Japan will suffer huge loss at least in the short term.
The international community owes a big “thank you” to Japan for all it has done for the Games despite the postponement. That’s why the Games will still be called the Olympic and Paralympic Games Tokyo 2020 despite taking place in 2021. The Olympic flame will also remain stored and displayed in Japan.
More importantly, all members in the Olympic family, guided by the Olympic spirit of respect and understanding are morally bound to stand behind Japan to go through this most difficult moment in the Games’ history.
1. What does the word “it” in Paragraph 3 refer to?| A．The decision. | B．The Games. | C．The pandemic. | D．The war. |
| A．Wisely. | B．Recently. | C．Easily. | D．Precisely. |
| A．the Games should be put off in times of war and disaster |
| B．the Games will still be called Tokyo 2020 Games for its sacrifice |
| C．postponing the Games will have a bad influence on the athletes |
| D．the Olympic family will have to make up for the loss of Japan |
| A．The whole world will support Japan. | B．Japan will keep the Olympic flame burning. |
| C．Postponing the Games will bring the world hope. | D．Tokyo will become the symbol of the Games. |
8 . If you’re planning on travelling, there are a few simple rules about how to make life easier both before and after your journey.
First of all, always check and doublecheck departure(出发) time. It is amazing how few people really do this carefully. Once I arrived at the airport a few minutes after ten. My secretary had got the ticket for me and I thought she had said that the plane left at 10:50. When I arrived at the airport, the clerk at the departure desk told me that my flight was closed. Therefore, I had to wait three hours for the next one and missed an important meeting.
The second rule is to remember that even in this age of credit cards, it is still important to have at least a little of the local currency with you when you arrive in a country. This can be necessary if you are flying to a place few tourists normally visit. A few years ago I was sent to Tulsa, Oklahoma. I flew there from London via Dallas, with very little time to change planes in between. I arrived there at midnight and the bank at the airport was closed. The only way to get to my hotel was by taxi and because I had no dollars, I offered to pay in pounds instead.
“Listen! I only take real money!” the driver said angrily. Luckily I was able to borrow a few dollars from a clerk at the hotel, but it was very embarrassing.
The third and last rule is to find out as much as you can about the weather at your destination before you leave. I feel sorry for some of my workmates who travel in heavy suits and raincoats in May, when it is still fairly cool in London or Manchester, to places like Athens, Rome or Madrid, where it is already beginning to get quite warm during the day.
1. According to the passage, it’s obvious that ________．| A．the author learns some rules of travelling from his own experience |
| B．the author doesn’t plan his trips or journeys carefully |
| C．Englishmen like to wear heavy suits wherever they travel |
| D．the American taxi driver never travels to England |
| A．Where you will go. | B．When you will leave. |
| C．How you will travel. | D．Whom you will go with. |
| A．London. | B．Manchester. | C．Dallas. | D．Tulsa. |
| A．The author tells people to choose warm places as their travel destinations. |
| B．You should remember to take credit cards when travelling. |
| C．You should know more about the weather of the place you’ll visit. |
| D．You should take enough change when you travel to another country. |
9 . 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 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.

10 . Do you want to live another 100 years or more？Some experts say that scientific advances will one day enable humans to last tens of years beyond what is now seen as the natural limit of the human life span.
“I think we are knocking at the door of immortality(永生),”said Michael Zey，a Montclair State University business professor and author of two books on the future. “I think by 2075 we will see it and that's a conservative estimate（保守的估计）.”
At the conference in San Francisco，Donald Louria,a professor at New Jersey Medical School in Newark said advances in using genes as well as nano technology（纳米技术）make it likely that humans will live in the future beyond what has been possible in the past. “There is a great push so that people can live from 120 to 180 years,” he said. “Some have suggested that there is no limit and that people could live to 200 or 300 or 500 years.”
However, many scientists who specialize in aging are doubtful about it and say the human body is just not designed to last past about 120 years. Even with healthier lifestyles and less diseases, they say failure of the brain and organs will finally lead all humans to death.
Scientists also differ on what kind of life the super aged might live." It remains to be seen if you pass 120, you know; could you be healthy enough to have good quality of life？" said Leonard Poon，director of the University of Georgia Gerontology Centre." At present people who could get to that point are not in good health at all."
