1 . "True friendship is like sound health. The value of it is seldom known until it is lost," Charles Caleb Colton said. Just like in any other relationship, arguments and fights are also part of friendship. You will hardly find friends who have never fought with one another. Whatever the reason is, if a person feels that he is responsible for causing the differences, it is important that he should apologize to his friend.

Though you can use the email, text messages or chat for expressing your apology, the good old way of saying sorry to your friend through a letter will surely have a great effect on him. This will make your friend realize that your efforts of saying sorry are genuine and that you really care about him.

Points to Remember:

Timing: Write the letter at the proper time. It is not advisable to put it off for too long.

Words: While you are writing the letter, what matters most is that you truly feel sorry.

Sequence: Always begin by apologizing and saying sorry for your mistake. Then explain to him your side of the story. In the third and last paragraph, talk about what his friendship means to you and make a promise of not repeating the mistake.

Delivery: You should either post the letter or deliver it personally or through someone else. You can also keep it at a location where your friend will be able to find it easily.

Some people may try to point out the friend's mistake while writing the letter. Avoid this completely, as it can make matters worse. The letter has to be brief and should only talk about the subject that has led to your apology. Keep patient and do not expect immediate results. In some cases, it may take time for the person to forgive and forget.

3 . As the effects of climate change become more disastrous, well-known research institutions and government agencies are focusing new money and attention on an idea: artificially cooling the planet, in the hopes of buying humanity more time to cut greenhouse gas emissions.

That strategy, called solar climate intervention (干预) or solar geoengineering, involves reflecting more of the sun’s energy back into space — abruptly reducing global temperatures in a way that imitates the effects of ash clouds flowing out from the volcanic eruptions. The idea has been considered as a dangerous and fancied solution, one that would encourage people to keep burning fossil fuels while exposing the planet to unexpected and potentially threatening side effects, producing more destructive hurricanes, wildfires floods and other disasters.

But. as global warming continues, producing more destructive hurricanes, wildfires floods and other disasters, some researchers and policy experts say that concerns about geoengineering should be outweighed by the imperative to better understand it, in case the consequence of climate change become so terrible that the world can’t wait for better solutions.

One way to cool the earth is by injecting aerosols (气溶胶) into the upper layer of the atmosphere. where those particles reflect sunlight away from the earth. That process works, according to Douglas MacMartin, a researcher at Cornell University.

“We know with 100% certainty that we can cool the planet,” he said in an interview. What’s still unclear, he added, is what happens next. Temperature, MacMartin said, is an indicator for a lot of climate effects. “What does it do to the strength of hurricanes?” he asked, “What does it do to agriculture production? What does it do to the risk of forest fires?”

Another institution funded by the National Science Foundation will analyze hundreds of simulations of aerosol injection, testing the effects on weather extremes around the world. One goal of the research is to look for a sweet spot: the amount of artificial cooling that can reduce extreme weather events without causing broader changes in regional rainfall patterns or similar impacts.

A．He thinks more research remains to be done.

B．He is optimistic about the effect of cooling the earth.

C．He is concerned about the reduction in agriculture production.

D．He disapproves of the practice of solar climate intervention.

4 . An aircraft carrying personal protective equipment donated by China, along with U.S.-purchased medical supplies, arrived in New York on March 29.

The plane is the first in a series of flights over the next 30 days organized by the White House to help fight the coronavirus, the White House said. Most of the purchases are from Asia including Malaysia and Vietnam.

The Chinese Embassy in the U.S. retweeted a report from Axios, which said that 12 million gloves, 130,000 N-95 masks, 1.7 million surgical masks, 50,000 gowns, 130,000 hand sanitizer units, and 36,000 thermometers from China have arrived in the United States.

Along with the goods, Chinese company Huawei donated 10,000 masks, 20,000 articles of protective clothing, 10,000 gloves and 50,000 goggles to New York state.

Governor Andrew Cuomo confirmed the donation and thanked Huawei on Twitter.

The plane was funded by the Federal Emergency Management Agency. It landed at John F. Kennedy airport carrying gloves, gowns and masks for distribution in New York, New Jersey and Connecticut, three hard-hit states battling to care for a crush of coronavirus patients.

The airlift is a product of a team led by White House senior adviser Jared Kushner, which formed "Project Airbridge," a partnership between large U.S. healthcare distributors such as Mekesson Corp, Cardinal, Owens & Minor, Medline and Henry Schein Inc, and the federal government.

The flight from Shanghai was the first of about 20 flights to arrive between now and early April, according to the White House. Additional flights will carry similar gear from China, Malaysia and Vietnam.

5 . The Chinese word "Shanzhai" means a small mountain village, but it becomes an accepted name for fakes (假货), after "Shanzhai Cell-phones" produced by small workshops in southern China became popular in the mainland market over the past two years. Now besides "Shanzhai" electronic products, there are "Shanzhai" movies, "Shanzhai" stars and even a "Shanzhai" Sprin Festival Gala, a copy of the 25-year-old traditional show presented by CCTV on Chinese Lunar New Year's Eve.

"Shanzhai" has become a culture of its own, meaning anything that imitates something famous. In Chongqing, "Shanzhai" version "Bird's Nest（鸟巢）" and "Water Cube（水立方）" woven by farmers with bamboo attract(吸引) wide attention from tourists. Both are copies of the famous Olympic buildings in Beijing.

A literature critic said that taking the "Shanzhai" Gala as an example, when the traditional CCTV program becomes less and less attractive to the audience, the "Shanzhai" version appears timely to attract people. "Although it is often connected with poor techniques and operation, 'Shanzhai' culture meets the psychological needs of common people and could be a comfort to their minds," he said.

To the mainstream（主流） culture, the rise of "Shanzhai" culture is a challenge and a motivation（推动）. People believe different kinds of cultures developing together is a perfect way and it is for the public to choose.

6 . When I was a child, I often saw my Grandma throwing bread that was no longer fresh to birds. Not surprisingly, this attracted few birds. Later on, we discovered bird food at the local store. Feeding garden birds in the UK has come a long way since then. Today, the birds can enjoy many kinds of food: from plant seeds to sunflower hearts and from cakes to meat balls. All this comes at a huge cost of about £200m a year. Sometimes, I wonder if we might be feeding our garden birds better than our kids. But maybe it’s worth it. Our generosity is having an important effect on the behavior and even evolution of these birds.

Take the goldfinch for example. In the 1960s, this was a rare bird. Today, goldfinches can be seen in many gardens. Other new visitors include the spotted woodpecker, which has left its usual woodland for food on bird tables. Evolution is meant to progress slowly: over thousands of years. Yet during the past few decades, the beaks of many kinds of birds have become longer because birds with longer beaks can get more food, and then are more likely to live on.

Actually, the British habit of feeding garden birds goes back much further. During the sixth century, St Serf of Fife fed a robin in his garden; during the winter of 1890, workers in London were seen giving their lunches to songbirds. The real change took place in the 1980s, when a few farsighted businessmen realized that encouraging the British to be more generous to garden birds can help them make money. Therefore, various kinds of bird food and modern bird feeders were produced. As a result, the number of species using garden feeding stations increased very quickly, from about 10 to over 100. Then, in 2005, Springwatch came, which turned our love of garden birds into an entertainment show.

Is bird feeding completely good for birds? Not everyone thinks so. Studies by the Zoological Society of London have shown that by bringing together many birds, bird feeders may help the spread of disease. In Australia, some bird experts believe—probably wrongly—that bird feeding creates a “dependence culture”.

But we shouldn’t forget one major benefit of feeding garden birds—it connects millions of people to the natural world. This is especially important for people who seldom reach the wider countryside. As I write this, there comes some noise outside my window: several birds were singing and flying around in my garden. It’s a sight I could only imagine years ago, when feeding garden birds just meant throwing hard bread to them.

A．Feeding garden birds is a huge waste of money.

B．We spend quite a lot of money on the food of garden birds.

C．We should care more for our kids rather than garden birds.

A．These birds have given up traditional woodland.	B．Food for these birds becomes richer and better.
C．Longer beaks mean more chances of survival.	D．These birds grow faster than ever before.

3. What do some bird experts in Australia think of bird feeding?

A．It is completely good for birds.

B．It may help the spread of disease.

C．It connects more and more people to the natural world.

D．It may reduce birds’ ability to find food by themselves.

A．Annoyed.

B．Pleased.

C．Surprised.

D．Bored.

7 . Asia has long tradition of tea-drinking. And China is no exception.

However, lately more and more Chinese people are turning to a different drink. Coffee has become an increasingly popular choice of Chinese people living abroad and in the country’s huge cities. It is also a popular crop among those living in the mountains of southern Yunnan Province.

In big cities such as Beijing, coffee shops seem to be on nearly every major street corner. These shops are not just selling drinks from Starbucks, the world-famous coffee company. Coffee businesses from South Korea, Taiwan, HongKong and Britain are also operating in China.

Tea-drinking is steeped in the culture and traditions of many countries, like China and Japan. But is that changing? Are young people from Asia now choosing a cup of coffee instead of tea?

BeiBei Su is from China. She has been living in the United States for the past eight years. Before that, she lived in Italy for two years. Ms. Su says she likes tea better than coffee. But she adds that may not be true among the young generation in China. Many young Chinese people drink coffee socially ---when meeting with friends. Yang Lin lives in the U.S. but comes from an area in China famous for growing tea. She used to only drink tea while in China. But now, she says, she drinks both and for different reasons.

Yang Lin says that drinking coffee for her is a social event. She and her co-workers like to sit in a cafe and talk over a cup of coffee. Voyo is another Chinese woman who now lives in Washington, D.C. She says that after moving to the U.S. her tastes changed. We would call her a coffee convert, someone who now chooses to drink coffee.

With more people drinking coffee, many see an economic(经济的）opportunity for Chinese-grown beans. China-grown coffee could be a money-maker even if most of the coffee on sale in China is imported(进口的).

8 . When you are sitting in the car, do you ever notice the drivers looking over their shoulders or side to side in the car? Well, they are doing this to check their blind spots! Blind spots take driving extremely difficult and increase the potential for car accidents.

Fourteen-year-old Alaina Gassler from Pennsylvania noticed her mother struggling with blind spots while driving their family car. So she came up with an ingenious solution that won the first place and $25,000 in the Broadcom Masters Competition.

Blind spots are the areas around the car that cannot be directly observed by the driver. There are two kinds of blind spots---on the back of the car that cannot be seen with mirrors, and blind spots at the front of the car as well.

When a driver is changing lanes, he has to look over his shoulder through the side windows to make sure that there is no vehicle in the blind spot. This invisible area is big enough to hide a car!

The other blind spot is created in the front by the A-pillar（柱子）---the material on either side on the windshield（挡风玻璃）that holds the glass and forms the frame of the car. In some cars, this pillar can be quite thick. Usually, people or cyclists can be hidden by this pillar.

Alaina's design was to get rid of the blind spot created by the front A-pillar of the car, the one that helps hold up the windshield.

She put a camera on the outside passenger side of the car which then sent the photos to a projector above the drivers' head. Then, she covered the inside of the pillar in reflective fabric onto which the image was projected. Basically, her device made the pillar "see through" and removed the blind spot on that side of the car.

Alnina's solution is very creative and could be improved by using LCD displays that will make it easier to see during day time as well.

3. How did Alaina solve the problem?

A．By improving the A-pillar.	B．By using a mirror on the outside of the A-pillar.
C．By relying on LCD displays.	D．By using a camera to capture images.

4. What's the best title for the text?

A．An Introduction to Blind Spots	B．A Warning About the Road Safety
C．A Teen's Creative Solution to Blind Spots	D．Scientific Research on Blind Spots

9 . Despite the negative international headlines that have hit Huawei over the past few months, its consumer business continues to thrive. The Chinese technology giant replaced Apple as the second­largest smartphone player by global market share last year. It's firmly the biggest vendor(销售商) in China.

Chinese consumers say they've been attracted to Huawei's newest features, the price points and the fact that it's a domestic brand.“Using Huawei's mobile phones is supporting domestic brands. We hope our brands can go international，” Vikey, a Guangzhou­based Huawei user, told CNBC. She added that Huawei phones are “cost­effective” and have good features while iPhones are “more of a trend”. One of the key features that Huawei introduced was a triple­lens camera on its P20 Pro, which was launched last year.

For the next 12 months, the iPhone lacks one of the most appealing features of current winners in the Chinese smartphone market, the triple­lens camera. The Huawei P20 Pro led the march.

Retailers (零销售) are slashing (大幅消减) iPhone prices across China as consumers say the phones aren't worth the cost. Apple's latest iPhone models are facing huge discounts in China as retailers try to sell the struggling devices. That comes as the top­of­the­line Apple smartphones have posted poor China sales on what experts say are too­high prices for the world's largest smartphone market and a lack of innovative features compared to local competitors like Huawei. The technology giant itself acknowledged earlier this month that unexpectedly low sales in the Chinese market would likely lead to worse­ than ­anticipated first quarter profits.

One of the most recent iPhone cost cuts in the country came from Suning, a large Chinese retailer, which changed the price of the 128GB version of the iPhone XR from 6,999 yuan to 5,799 yuan — a 1,200 yuan discount.

Other retailers in China are also putting their iPhones on sale. Sunion, an Apple reseller, was advertising 700 yuan off for both the 128GB and 256GB versions of the iPhone XR. E­commerce site Pinduoduo, which allows third­parties to sell products, also had hefty(很大的) discounts across all of the latest iPhone models.

1. What does the underlined word “thrive” probably mean in the first paragraph?

A．Reduce.	B．Remain.
C．Threaten.	D．Increase.

2. Which of the following is one of the Huawei's characters?

A．More of a trend.	B．Cost­effective.
C．Too­high prices.	D．A lack of innovative features.

3. Which of the following is a medium?

A．Suning.	B．Sunion.
C．CNBC.	D．Pinduoduo.

4. What can we infer from the text?

A．Updating of technology counts.

B．Advertising of the products matters.

C．The sale strategy is invisible.

D．The iPhone still leads the trend in China.

10 . Sales of Apple’s new iPhone 11 in China began on Friday, but were met with a cooler reception from consumers than in previous years. Unlike in previous years, no long lines were seen outside Chinese shops on Friday for the new iPhone, and the product release only made the headlines in a few media outlets.

Huawei unveiled its Mate 30 smartphone series on Thursday night. Its new devices have won consumers’ hearts at home and abroad. Many compared it with Apple’s new iPhone 11, saying that beats the new iPhone in terms of innovation and quality. One customer surnamed Zhao, an IT specialist who pre-ordered a Mate 30 Pro on Friday, said that he chose Mate 30 without hesitation. Zhao said, “It’s obvious that Huawei’s new phone with its advanced 5G mode would lead the future global telecommunications market, and its new innovative features in gesture and side control attracted my attention, too.”

In contrast with iPhone 11’s lukewarm sales, Chinese netizens have engaged in discussions on Mate 30 and Mate 30 Pro. An online poll on the Mate 30 and iPhone 11 on Weibo on Friday showed that more than 60 percent of netizens chose the Mate 30, while less than 20 percent chose the iPhone 11. Many chose Huawei not out of patriotism but for its technology.

Overseas consumers also engaged in vigorous discussions on Huawei’s new flagship devices on technology sites and social media platforms. On Twitter, many netizens said “nice”, “best phone ever” and “my favorite one” on Huawei’s Twitter account. Some netizens in countries like the UK, the Netherlands and Argentina asked when Huawei’s new devices would be released in their countries.
