While sweet treats can be hard to resist, the World Health Organization(WHO) has set new guidelines for people around the world. The guidelines, released on Wednesday, advise that both adults and children cut back on their sugar intake(摄取量) to stay healthy.

In a statement, Francesco Branca, director of the WHO’s nutrition department, said there is evidence that reducing daily sugar intake reduces the risk of being overweight and tooth decay(腐烂).

The guidelines do not apply to the sugars in fresh fruit and vegetables or those that are naturally present in milk. According to the WHO, there is no reported evidence of negative effects of consuming those sugars. Instead, the new guidelines focus on “added” or “free” sugars. These include sugars that are added to processed foods and drinks such as candy and soft drinks.

Added sugars are sometimes described as “ hidden” sugars because they exist in foods we might not think of as sweets, such as honey and ketchup(番茄酱). Health experts advise that consumers look at ingredients on food packages to help make better-informed decisions.

The WHO recommends that people in the United States, Europe and other Western societies should cut their average sugar intake by about two-thirds, or down to just 10% of their overall calories. For developing countries, where dental care is less advanced, the WHO recommends that sugar intake be reduced to 5%.

Scientist Kieran Clarke, of the University of Oxford, notes that for those people who can’t shake their love for sweets, getting more exercise is a good solution. “If you get enough exercise, you can eat almost anything,” she said “But it’s very hard to avoid large amounts of sugar unless all you’re eating is fruit and vegetables.”

1.What can we learn from the guidelines released by the World Health Organization?

A. The production of candies should be forbidden.

B. There is a connection between sugar intake and bad teeth.

C. Fruit and vegetables contain a lot of sugar.

D. People should cut down on sugar intake for the sake of their health.

2.To what level should people in developing countries cut down their sugar intake, according to the WHO?

A. 10%.            B. 15%.            C. 5%.            D. 30%.

3.We can learn from the text that ________.

A. added sugar isn’t marked on food packages

B. we should drink as little milk as possible as it contains sugar

C. soft drinks don’t contain added sugar

D. the less exercise you do, the fewer sweet things you should eat

On January 27th, in order to win the new pneumonia Resistance War (抗击新型肺炎战), the Ministry of Education issued a notice on putting off the start time of school in spring 2020. It was said that school should not start before February 17th. The exact start time of school will depend on situations and further notices.

However, many parents are very worried that putting off the start of school may affect children’s studies. It they have such a long winter vacation, children will not learn any knowledge, read books or study at all. They may forget what they have learnt before. Staying at home for a long time will make them keep eating, sleeping and playing, which seriously affect their physical and mental health.

In short, the close of school influences learning and develops bad habits, so how should we avoid these problems? Local education departments have also issued a notice, that is, to organize online teaching and create a network platform, where necessary courses will be shown every day, and online teaching will be given by excellent teachers of the subject, and students can learn at home through computer or mobile network.

It should be said that such a method is very good. It can not only keep students indoors and not worry about the infection of the disease, but also make them study at home, improve their learning ability, and truly achieve “no suspension of classes”. Both the platform itself and the recorded lesson resources are more useful, and are welcomed by parents and teachers.

Of course, except for learning at home, it is also necessary to teach children about health knowledge, especially how to keep away from touching virus; at the same time, it is also necessary for children to do some physical exercises or some games, which is good for physical health at home.

1.Parents worried about putting off the start time of school because ____.

A.children may be infected by virus

B.they don’t like the idea of online learning

C.children’s study may be affected

D.parents have no time to look after children

2.Except for learning at home, what is also necessary according to the writer?

A.To keep playing online games.

B.To keep touching different people.

C.To do some physical exercise outside.

D.To teach children about health knowledge.

3.The underlined word “suspension” in Paragraph 4 probably means ___.

A.plan B.stop

C.growth D.change

4.What’s the best title for this passage?

A.A Special Way to Learn at Home B.A New War with a New Change

C.A Way to Keep Mentally Healthy D.A Method to Make Parents Unworried

With petroleum reserve（石油储量）decreasing, the search is on to replace gas with a cleaner, greener alternative. Though much eco-talk has centered on biofuels from corn and soybeans, the biofuel that looks more likely to replace petroleum comes from a most unlikely source: algae（藻类）.

Algae, like corn, soybeans, and other crops, grow via photosynthesis（光合作用）and can be processed into fuel oil. However, they yield 30 times more energy than land crops such as soybeans, according to the U.S. Department of Energy. Many algae species also can grow in saltwater and polluted water—while corn and soy require arable(适于耕种的) land and fresh water that will be in short supply as the world’s population balloons.

“If you replaced all the diesel（柴油）in the U.S. with soy biodiesel, it would take half the land mass of the U.S. to grow those soybeans,” says Matt Caspari, chief executive of Aurora Biofuels, a Berkeley, Calif-based private firm that specializes in algae oil technology. On the other hand, the Energy Department says that if algae fuel replaced all the petroleum fuel in the United States, it would require only l5, 000 square miles, which is a few thousand miles larger than Maryland (12,407 squaree miles), the 42^nd state in land area.

Another advantages: Because algae can be grown just about anywhere in a closed space, they’re being tested at several power plants across the nation as a carbon absorber. Smokestack emissions（烟囱排放物）can be pumped directly into the ponds, feeding the algae while keeping greenhouse gases out of the atmosphere.

Although processing technology for algae fuel—also known as “oilgae” in some environmentalist circles —is improving, it’s still years away from reaching your local gas pump. “It’s just a question of cost, because no large-scale facilities have been built yet,” Caspari says.

1. The underlined word “yield” in Paragraph 2 can be replaced by “_______”.

A. control          B. require          C. produce      D. grow

2. Compared with corn and soybeans, algae_____.

A. may pollute water and soil          B. can grow in poor conditions

C. provide much less energy            D. need more special care

3.According to Paragraph 3, one of the advantages of algae fuel is that ____.

A. it can be used more widely           B. it is easier to produce

C. it needs much less land                              D. it costs much less money

4.Which of the following might be the best title for the text?

A. Environmental Protection             B. Biofuels from Corn and Soybeans

C. The False Hope of Biofuels               D. A Promising Oil Alternative

On Friday, the Food and Drug Administration (FDA) released two proposals to improve food safety. The regulations are a response to a series of recent foodborne illnesses. The FDA hopes these new rules will prevent problems of food in the earliest period of production, before the contaminated（受污染的）food causes consumers to get sick.

Over the past decade, foodborne illnesses have caused many people to get sick. Food like spinach（菠菜）, ground beef and cantaloupes（甜瓜）has been sent back to producers, because it is bound to contain germs and bacteria that cause illnesses.

Among the most common problems are dangerous bacteria that cause stomach pains and food poisoning. Often these illnesses occur when food is undercooked or improperly prepared. While not all illnesses are reported, the FDA estimates that nearly 130,000 Americans a year are hospitalized for food-related problems.

The two new rules proposed by the FDA are called Preventive Controls for Human Food and Standards for Produce Safety. Each rule is described in detail on the FDA’s website. Readers can submit comments, which the FDA will use as feedback to mike future adjustments to the proposals.

The first rule demands manufacturers should have formal plans for preventing contamination and for fixing problems when contamination occurs. This regulation is applied to food produced in the US and overseas.

The second rule k specific to food that is eaten raw. It requires strict standards of growing harvesting, and packing fruit and vegetables. Workers must make sure the materials used in soil are safe and free of contamination.

The FDA believes these new rules will not just improve Americans’ health but also make a positive economic impact. The regulations can lead to major savings in medical costs for people who get sick because of the contamination food.

If manufacturers are able to fix problems at source, they will prevent future issuer However, putting the proposals into action will lake lime and money.

1.Why are the two proposals released by the FDA?

A. To make sure food is safe　　 B. To increase the variety of food

C. To raise people’s health awareness　　 D. To prevent disease from s|>reading

2.Which way will you use to express your opinions about the two rules?

A. E-mail the FDA　　 B. Call the FDA office

C. Visit the FDA website　　 D. Write a letter to the FDA

3.Who are the two new rules proposed by the FDA intended for?

A. Food suppliers　　 B. Food manufacturers

C. Consumer　　 D. Food processors

4.What can you learn from the last two paragraphs?

A. More people will buy vegetables

B. Fewer patients will go to hospital for eating contamination food

C. Patients will spend more money on medical care.

D. The regulations are expected to come into effect soon.

Due to climate change, Arctic ice is breaking up earlier in the spring, and its area is decreasing. This is creating problems for polar bears that make their homes off northern Alaska and in Hudson Bay.

Polar bears off Alaska normally hunt and raise their young on ice sheets that float on the ocean. But as the ice has melted, the polar bears have been forced to spend more time on land. There, they have begun to frequent beaches, feeding on the remains of whales caught by native hunters. For polar bears, this food is less nutritious than seals that they normally catch on ice sheets. The shrinking（减少） ice has also forced more polar bears into the ocean. In the past, they only had to swim short distances between ice sheets. But as the ice has shrunk, polar bears have been forced to swim longer and longer distances in the open ocean. This poses a severe danger during rough weather, and an increasing number of drowned polar bears have been observed.

In Hudson Bay, the ice breaks up three weeks earlier in the spring now than it did 20 years ago. Polar bears on Hudson Bay fast（绝食） during the summer, waiting for ice to form in the fall to hunt. Every year, the summer gets longer, and the bears get skinnier. Over the past 25 years, the average weight of the female bears has dropped 68 kg. This loss affects their ability to reproduce, and already the number of births has dropped 15 percent. Unless the bears can learn to survive these climate changes, these giants of the ice may one day disappear.

1.What is Arctic ice doing earlier each year?

2.What is true of polar bears that are spending more time on land in Alaska?

3.What do polar bears in Hudson Bay do during the summer?

4.In which publication would you most likely find this passage?

According to the Ministry of Health, 260 million Chinese people have chronic（慢性）diseases, and 85 percent of all deaths in China are caused by such diseases．Among them, cardiovascular（心血管的）disease has bothered more people than any other kind of chronic disease．

According to the WHO（World Health Organization), salt consumption（消耗）, one of the key causes of high blood pressure that can lead to cardiovascular disease, is much higher in China than in other countries．

Douglas Bettcher, the director of the WHO’s Tobacco Free Initiative, says, “The average Chinese person consumes about 12 to 14 grams （of salt) per day, while the suggestion of the WHO is consumption of less than 5 grams per day．High salt consumption is a major cause of cardiovascular disease and high pressure in China．

Changing the way that food is prepared could reduce salt consumption in China．

Another major risk factor in China is smoking．Dr Michael O’Leary, a representative of the WHO, says, “We know already that one million deaths in China are related to smoking, This is an enormous number．It means that we are seeing nearly 3000 deaths a day in China, or two deaths every minute, related to smoking．

According to O’Leary, about 26 percent of men who die from smoking-related diseases in China die before the age of 60．People who can still contribute a great deal, in other words, are dying too young．

China has tried to ban smoking , but more efforts are needed．

More than half of chronic diseases are preventable by changing lifestyles and reducing risks．The four key risk factors are: smoking, diets high in fats, salt and sugar, environments that prevent physical activities, and alcohol consumption．These are the areas on which efforts to make changes need to concentrate．

1.Which of the following is more in China than in other countries?

A．The amount of salt consumed

B．The number of deaths caused by high blood pressure．

C．The number of people with cardiovascular disease．

D．The number of people with high blood pressure．

2.According to the WHO, how much salt should a Chinese person consume?

A．About 12 to 14 grams per day．

B．Less than 5 grams per day．

C．About 17 to 19 grams per day．

D．About 7 to 9 grams per day．

3.Why does O’Leary mention “26 percent of men” in Paragraph 6?

A．To show China needs to try to ban smoking．

B．To show smoking causes the deaths of elderly people．

C．To show smoking causes the deaths of too many young people．

D．To show the number of smoking-related deaths in China is large．

4.What can be inferred from the last paragraph?

A．There are four causes of chronic diseases．

B．The change in lifestyles can prevent some chronic diseases．

C．No smoking or alcohol means no chronic diseases．

D．If we do physical activities, we will have no chronic diseases．

The government has proposed to spend money developing wireless charging roads in the UK as part of a ￡40 million plan. Wireless charging roads could be developed to recharge electric cars while they drive along to solve some problems about limited equipment to encourage ownership of these vehicles and ensure better air quality. The government has promised the money to developing both on-street and wireless charging to help transformation from internal combustion engine(内燃机)cars to electric cars.

These systems work similarly to a Scalextric toy car. Wireless charging uses a process called electromagnetic induction(电磁感应)to move energy. On the ground is a pad in which electricity is passed through a set of wire to create a magnetic field. It is then moved to a receiver on the underside of the car. Once the technology works, it could mean that drivers can fill up their cars as they drive along, meaning there could be longer periods between charging.

The proposal was made in Department for Transport (DFT) and could also see charging points positioned at service stations and car parks. New homes will also, where permitted, be built with some points. David Martell, of the electric car charging company BP Chargemaster, said, "Wireless charging will make driving an electric vehicle as similar as possible to driving a petrol car but without going to the petrol station frequently."

This is not the first time that wireless charging roads have been proposed as a number of firms have developed technologies. Renault partnered with Qualcomm and VEDECOM Tech to develop a road to test the technology's capability. The 100-meter test track was said to be capable of a charge up to 20 kilowatts at speeds up to, and over, 62 miles per hour (nearly 100 km/h).

1.What's the attitude of the UK government to electric vehicles?

A.Supportive. B.Unfavourable.

C.Indifferent. D.Objective.

2.What is the second paragraph mainly about?

A.How a Scalextric toy car functions. B.How the electric cars get charged.

C.How the wireless road systems run. D.How the electric cars benefit people.

3.How does David Martell find the new technology?

A.It gets petrol cars unfavourable. B.It saves drivers' trips to petrol station.

C.It gives rise to many new car parks. D.It makes electric cars difficult to drive.

4.Why does the author mention the figures in the last paragraph?

A.To show the experiment of some firms.

B.To announce the progress of the new technology.

C.To show the efficiency of the wireless road systems.

D.To encourage the cooperation among different firms.
