1 . The World Health Organization(WHO)says it is possible to defeat the disease malaria （疟疾）,although that is not likely to happen with the current methods.
Pedro Alonso, directing the United Nations agency's global malaria program, says the WHO wants to eradicate(根除）the disease but “with the tools we have today, it is most unlikely that the goal will be achieved.”
Malaria infected around 219 million people in 2017, when about 435,000 people died from the disease. The large majority were babies and children in the poorest areas of Africa. These totals little changed from 2016.But the numbers are smaller than the 239 million infections and 607,000 deaths reported in 2010.Diallo is head of the RBM Partnership to End Malaria. The group released a statement from him on the WHO report, saying, “Today, there are more countries without malaria than with it, and more countries than ever have fewer than 10,000 malaria cases.”
WHO officials have long wanted to destroy malaria. The United Nations agency first attempted a campaign against the disease in 1955.Now, the Bill and Melinda Gates Foundation is providing financial support for the latest efforts.
There are a number of drugs available to successfully treat malaria. Sleeping under chemically-treated bed nets has proven to be effective in order to control malaria-carrying mosquitoes and infections. The drug company GSK has also developed a vaccine that has proven partially effective against malaria. The vaccine is currently used in Ghana and Malawi. But the WHO's report says these tools will not be enough to end the threat from malaria altogether. It calls for research and development of“transformative tools and knowledge” to control mosquitoes and create more effective medicines to prevent and treat the disease.

2 . Chef Xiang Chunqin lowered the fire on the stove where she was cooking her Cantonese meal. She added all the necessary ingredients, including the seafood, shrimp. She quickly lowered the fire and turned toward a phone camera as hundreds of people watched her online. "It ruins the dish if you burn the breadcrumbs, "She advised her live-stream video watchers.
Many people in China are restricted to their homes in the effort to stop the spread of coronavirus. Millions of them are finding a new interest in cooking. People watching television and online cooking shows are learning how to make Chinese and Western foods. They are also pushing up the sale of special cookware on online markets, because cooking tools matter to some recipes. Downloads of the top five recipe apps doubled in February, said research company Sensor Tower, i.e. more than 2 million downloads. The Chinese video streaming company Billibilli said it has had more than 580 million views of its cooking videos in the two months since the coronavirus began to spread in China.
Another online cooking show producer DayDayCook told reporters its number of new users increased 200 percent from January to February. A recipe for bean curd and shrimp received the most views.

3 . Nowadays some companies are attempting to grow seafood from cells in a laboratory rather than harvesting it from the oceans.
With massive problems with overfishing worldwide and growing demand for shrinking supplies of seafood, the way fish currently makes its way to our plates isn't a long-term viable option. Between 1961 and 2016, the average annual increase in global food fish consumption outpaced population growth. Those are figures not sustainable for us, the fish or the environment as a whole.
Cellular seafood could be the answer. Just don't make the mistake of calling it lab-grown fish. ''None of us in the industry would call it lab-grown seafood, '' says Mike Selden, CEO of Finless Foods. ''Finless Foods isn’t lab-grown. We experiment and create our science in the lab, but don't produce there. Our products come from a production base much like a farm as a production base for animals.''
Finless Foods is a tech company in San Francisco. Beginning in 2017, it's been working to bring to market a species of cultured bluefin tuna (蓝鳍金枪鱼) created using cellular technology. Shortly after that, the company produced its first pound of bluefin tuna meat for a cost of about $19,000. Since then, however, it's been working to bring that price down.
Selden terms what Finless Foods is doing as ''cell-based seafood''. ''We're growing seafood from real seafood cells,'' Selden explained. ''We take cells from a fish once, and then grow them endlessly from that. We do the same process that happens inside of a fish and make it happen outside of a fish. ''
The goal of cellular seafood isn't to entirely destroy the current seafood industry. Instead, it's intended to augment it—and perhaps to help reduce some of the more harmful aspects of current fishing practices like overfishing and illegal fishing. And when it comes to certain sea species, this laboratory-based approach could help create a plentiful supply of certain fish without endangering the survival of certain overfished species as a whole.

4 . When people travel abroad, they may get the anxiety and feelings of surprise and confusion(困惑) felt when they have to operate within a different cultural and social environment. Besides, maybe when they come back to their own country, they will meet the reverse cultural shock. There is no doubt that people are experiencing cultural shock. So, what is cultural shock? And what causes cultural shock? We interviewed John Robb, Cristal and Jim about their feelings of facing cultural shock abroad.
John has been in China for 24 years. In his opinion, he thinks people wail a long time to make decisions in China. And in his culture, they usually make most decisions far in advance. So, that's a big difference.
Cris has been in Australia for 2 years. He thinks people from different countries speak different languages. And he usually speaks English with them. In learning, there are many people who are willing to communicate with him about different regional cultures. Australians eat more meat and high-calorie foods. And some raw vegetables go with their diet.
Jim has been in Britain for 7 years. He liked that freedom very much at first in Britain And he traveled to a lot of places and met a lot of people. But over time he found he had to say goodbye to them. Therefore, he became sad little by little. After wandering for a long time, he really looked forward to finding a sense of belonging.
As John said, " Every culture does things differently. So, you have to learn the new ways. ” Facing differences, the most important thing is to make changes. After staying in China, John enriched his experience, learned to think about his future and wanted to open a new life. After studying in Britain, Jim became independent, sensible and learned many life skills.

5 . Wherever we look, we see advertisements that attract us to buy. In today’s society, we are under pressure to constant shop. Of course, most people only buy what they need and what they can afford. However, there are some people called shopaholics, who can’t control their desire to spend money buying things. This kind of addictive behavior can lead to money problems, family conflicts, and deep unhappiness.
What are the symptoms of a shopaholic? People with this problem often spend hours and hours shopping on the Internet or at the mall. Their closets are full of clothing and jewelry that they have never worn, with the price tags still on them. Their homes may be filled with shopping bags and boxes that they bought but never used. Many shopaholics are aware of their own problems, but when they go to a store, they simply can’t resist the urge to buy. Some of them are ashamed of their weakness and try to hide it by storing their purchases in places like the attic(阁楼), where others won’t see them.
Psychologists think there are several reasons for a shopping addiction. For some people, it is a way of reducing stress. For others, shopping is a way to fight loneliness or depression. For people with less confidence, shopping can be a way that they prove their self-worth. Sometimes the problem develops out of boredom. It replaces other hobbies and interests to help kill the time. Although shopping can temporarily make people feel good. they often feel ashamed and guilty later.
When shopping habits get out of control, people need professional help. They can either see a counselor(顾问) or join an organization such as Shopaholics Anonymous. Groups like this try to help people understand the reasons for their addiction and learn how to control the urge to shop. Their goal is to help people find ways to fulfill themselves rather than lead to serious debt and troubled lives.

6 . In a country known for high-tech ambitions and giant state-owned firms, the plight of street hawkers may seem insignificant. But in China these days, people like Shui Jin, an old lady riding a wooden cart filled with fruit, are in the spotlight.
Faced with rising unemployment, officials have concluded that pavement stands can help solve the economy’s problems. Shui Jin, who used to face the danger of heavy fines, may sell her fruit with more confidence as she slowly makes her way through the narrow lanes of Suzhou. Her family needs the money. Both her daughters-in-law recently lost their jobs, among the tens of millions in China hurt by the coronavirus outbreak.
The government’s support for street hawkers is something of an about-turn. For years Municipal authorities pushed out hawkers, trying to tidy up the colourful chaos that once characterized China’s cities. In the name of “civilizing” urban life, they wanted to see dumplings, plastic toys and T-shirts bought inside shopping malls, not sold from the back of carts. But on June 1st Li Keqiang, the prime minister, signalled a change. Stopping by a snack stand in the city of Yantai, he declared that street hawkers and small shops were vital to the economy. “Only when the people are in good shape can the nation be in good shape,” he said.
Mr. Li’s compliment has produced a feeling of excitement about the revival of China’s “street- stand economy”. At least 27 provinces and cities have announced that they will create markets for hawkers or, in some cases, let them move their things being sold onto the pavement in front of their shops. The shining example is Chengdu, a busy and noisy city in Sichuan province in the south-west, where businesses started setting up street stands in March. The local government there claims that more than 10000 jobs have been created in the process.

7 . The popularity of Chinese-owned video-sharing service TikTok (抖音) continues to grow among young people in the United States. In 2019, experts say the service more than doubled its American user base to 37 million. TikTok is especially popular with teens and young adults.
The service lets users create and share their short videos that they think interesting and useful, and many of them are under 15 seconds. The TikTok app offers a wide choice of sounds, brief parts of songs and special effects tools to help create a video. Some TikTok-based memes are very popular. Videos often include popular songs from well-known artists and TikTok has even helped launch the careers of new music stars.
TikTok is considered a competitor to the video-sharing app Snapchat, as well as Facebook’s Instagram service. Snapchat and Instagram also mainly interest young users with a wide mix of photos and videos centered largely on fashion, pop culture and humor.
Last year, TikTok was the second-most downloaded app from Apple and Google stores. Only WhatsApp was downloaded more. Research company Sensor Tower guesses people have downloaded the TikTok app 1.65 billion times.
TikTok has been used by many major companies to reach young people who use little or no traditional media. One of those companies is American-based e. l. f. Cosmetics. The makeup company’s chief marketer, Kory Marchisotto, said that TikTok is “where the Gen Z party is”. Gen Z is a name used to call the generation born between the late 1990s and the early 2000s. “That’s where they’re all hanging out,” Marchisotto said.
Companies appearing on TikTok can make money through advertising. Often, the companies create user “challenges” as part of their ad campaigns. In challenges, users are invited to publish their own videos in which they perform similar dance moves. One campaign by e. l. f. Cosmetics, for example, asked people to wink and move their lips while following a song. TikTok users created 3 million videos that received more than 4 billion view.

8 . American children are still eating lots of fast food---and in spite of restaurants’ promises of healthy options, most kids are sticking with fries over salads. Some infamous chains like McDonald’s and Wendy’s have promised to offer healthier options on their kid’s menus, but they aren’t all sticking it, according to a report from the Rudd Center.
In fact, nearly all parents are buying their kids at least one fast food meal a week. Healthy fruits and vegetables may be all the rage among adults, but busy parents still choose quick meals for themselves and their kids. It doesn’t look like fast food is going away any time soon.
Scientists at the Rudd Center surveyed about 800 parents in 2010, then again in 2013 and 2016. Things have not improved much over the years. Of the vast majority of parents who had made a trip to McDonald’s, Burger King, Wendy’s or Subway in the last week, 74% ordered an unhealthy side or drink. The older the children, the more likely their parents were to choose fries instead of a fruit, or a similar less healthy menu item. And about 35% of parents ordered regular adult menu items for their 2 to 11--year-old children, meaning these kids were often getting larger, less nutritious lunches and dinners.
Even as they introduced options like fruit juices, low-fat milk and yogurt to their menus, some restaurants have also added desserts and other calorie-heavy options to their kids’ menu items. So despite what’s now on offer, kids are getting equally or less nutritious meals, nowadays, which is mostly because fast food restaurants still promote their unhealthy options, and sides like fries are still allowed.
“While most fast-food restaurants do have healthier kids’ meal drinks and sides available, many do little to make parents aware of the healthier options or to encourage parents to choose the healthier options instead of unhealthy ones,” said lead study author Jennifer Harris. “If restaurants are serious about children’s health, they will make the healthiest choice and easiest for parents and the most appealing choice for children.”
1. What do the underlined words “all the rage” in Paragraph 2 mean?| A．popular. | B．necessary. | C．potential. | D．modern. |

| A．Fruits juices. | B．Desserts. | C．Low-fat milk. | D．Yogurt. |
| A．Offer healthier meals for kids. | B．Take children’s health seriously. |
| C．Be honest about their business. | D．Guide parents how to order a healthy meal. |
9 . The way individuals collectively remember, forget, and recall event, people, places, etc, has been an important topic of research on collective memory.
More recently, memory study scholars tend to stress the significance of the media in shaping collective memories: “Culture and individuals’ memory are constantly produced through the technologies of memory.” Under this perspective, research often involves content analysis of news and the use of surveys or interviews for analyzing the public memory.
However, developments in digital technologies in recent years have significantly influenced how we keep track of events both as individuals and as a collective. “The Internet doesn’t forget.” The Internet has had strong impacts on memory and the processes of remembering and forgetting.
| A．Research on collective memory is often based on various aspects. |
| B．There are a few simple things a person can do to help improve their memory. |
| C．Maurice Halbwachs is recognized as the father of collective memory research. |
| D．Although all Americans recalled similar events,the interpretation changed over the generations. |
| E．Also,scholars have studied the role of journalists as collective memory agents by analyzing their stories. |
| F．Recently developed information technologies have affected how we create,store and recall information. |
| G．Meanwhile,it has transformed collective memory into an observable phenomenon that can be tracked and measured online. |
10 . Just how much does the Constitution(宪法) protect your digital data? The Supreme Court will now consider whether police can search the contents of a mobile phone without a warrant (授权令) if the phone is on or around a person during an arrest.
California has asked the justices to restore the practice that the police may search through the contents of suspects’ smartphones at the time of their arrest. It is hard, the state says, for judges to assess the implications of new and rapidly changing technologies .
The justices would be careless if they followed California's advice. They should start by rejecting California’s weak argument that exploring the contents of a smart phone is similar to say, going through a suspect's wallet. The court has ruled that police don't offend against the Fourth Amendment(修正案) when they go through the wallet of an arrestee without a warrant. In fact, exploring one's smartphone is more like entering his or her home. A smartphone may contain an arrestee's reading history, financial history, medical history and comprehensive records of recent correspondence.
Americans should take steps to protect their own digital privacy and should avoid putting important information in smartphones. But keeping sensitive information on these devices is increasingly a requirement of normal life. Citizens still have a right to expect private documents to remain private and protected by the Constitution's prohibition on unreasonable searches.
In many cases, it would not be very difficult for authorities to obtain a warrant to search through phone contents. They could still trump(打出王牌) the Fourth Amendment protections when facing severe and dangerous circumstances, such as the threat of immediate harm, and they could take reasonable measures to ensure that phone data are not deleted or altered while a warrant is on the way. The justices, though, may want to allow room for police to cite situations where they are entitled to more flexibility.
But the justices should not swallow California's argument whole. New technology sometimes demands fresh applications of the Constitution's protections. Orin Kerr, a law professor, compares the explosion and accessibility of digital information in the 21st century with the establishment of automobile use as a digital necessity of life in the 20th. At that time, the justices had to explain new rules for the new personal domain(领域) of cars. Similarly, the justices must sort out how the Fourth Amendment of the Constitution applies to digital information now.
