Many people think the novel coronavirus will disappear as the temperature     1     (go) up. However, whether it will or not is still uncertain. Experts have warned that it is unwise to bet on the hot weather     2     (stop) the spread of the virus.

An official of the WHO Health Emergencies Program stated that     3     present there is no clear evidence     4     (suggest) COVID-19 will disappear in the summer. “We still have no idea how the virus will behave and spread in different climatic     5       (condition),” said the official, warning against the prediction that the virus would just disappear by     6     (it) in the summertime like other typical flu virus.

A professor from Harvard University disagrees with those     7     believe that changes in weather will make     8     difference in how the virus spreads. “COVID-19 has now been documented around the world. If the virus is anything like a typical flu virus, it may worsen     9     (great) in Southern Hemisphere regions(南半球地区) as the seasons change.” Another professor from Peking University also has the opinion that although warmer temperatures disadvantage virus spread, people shouldn’t count on it. “Compared with the unreliable theories, taking personal protective measures     10     (be) much more practical and effective.”

3 . Japanese researchers are genetically changing mosquitoes so that they become carriers of a vaccine (疫苗) that could vaccinate millions for free. The researchers have already genetically changed a mosquito species so that its saliva (唾液) contains a protein that acts as a vaccine against leishmaniasis(利什曼病）, a deadly disease that leads to terrible skin problems. The team confirmed that mice bitten by the genetically-engineered mosquito developed an antibody to the disease, meaning they had built up immunity (免疫力).

“You would be vaccinated without even noticing. You wouldn’t need any drug and you wouldn’t need to show up at a fixed place for mass vaccinations,” said Shigeto Yoshida, the associate professor who has led the research. “Repeated bites would only strengthen the immunity.”

Similarly the mosquitoes could be used to help treat malaria (疟疾),     perhaps a decade from now, said the malaria expert.

Nearly one million people die each year from malaria ---- most of them are children ---- mainly in Africa and Asia, according to the World Health Organization. Now a problem is that no effective vaccine exists. “There is a treatment that works, but it is beyond the reach of people who need to worry about food for tomorrow,” Yoshida said.

However, Yoshida expects that the genetically-engineered mosquito will finally help wipe out the deadly disease in the developing world. “Technically speaking, I believe it’s a matter of 10 years or so, but it’s not clear whether society would accept it,” he said.

Another problem is that the genetically-engineered mosquito may still pick up and spread the infected blood of a person who has already caught malaria. Yoshida’s team is hoping it can solve this problem by developing a mosquito species that kills the malaria virus inside its own body.

1. How have scientists turned mosquitoes into carriers of a vaccine?

A．By changing their genes.	B．By killing the virus in their bodies.
C．By letting them bite mice.	D．By injecting vaccines into their bodies.

2. Which of the following is NOT an advantage of using mosquitoes as vaccine carriers?

A．It’s free of charge.	B．It’s convenient.
C．It’s more effective.	D．It’s unnoticeable.

3. What can we infer from the last two paragraphs?

A．People welcome the idea of using mosquitoes to treat malaria.

B．Mosquitoes carrying vaccines may still spread malaria.

C．It is not long before people will use mosquitoes to get rid of malaria.

D．A mosquito can kill the malaria virus inside its own body.

4. The main purpose of the passage is to         .

A．introduce a possible solution to malaria

B．encourage people to use mosquitoes to fight against diseases

C．show that Japan has very advanced technology

D．call on people to help people suffering from malaria in Africa and Asia

4 . There are many programs for high school students today that help lonely teenagers deal with loneliness. However, loneliness is not only a problem for teens but also an important and rarely acknowledged one in the elderly.

In Britain, Tracey Crouch was appointed to be the first Minister of Loneliness in order to address the problems caused by loneliness. This is the first time such a position has been created.

In Britain, there are around 9 million people who say they are lonely frequently. In Germany, a study conducted by Ruhr University Bochum found that 20 percent of people over the age of 85 felt lonely, and 14 percent of those between age 45 and 65 felt socially lonely. In the United States, more than 25 percent of the population live alone, more than 50 percent are unmarried.

Loneliness is generally associated with heart disease, overweight, and anxiety. Additionally, the stress from loneliness can cause your cells to change on a molecular (分子) level that reduces its abilities to defend your body against diseases. In fact, doctors believe having feelings of loneliness is equivalent to smoking 15 cigarettes per day in regard to its effect on health!

In Britain, the new Minister of Loneliness will help introduce government policies on the problem and fund a charity—an organization for helping people in need, to devote their efforts towards aiding loneliness. There are charities that link lonely seniors to high school students in order to give them a line of communication whenever they feel lonely!

The possibilities for the new Minister of Loneliness are endless. For example, she can provide education services to household businesses so that they can identify lonely customers if they see one. Loneliness fits into the category of being a social problem that must be monitored by the entire community in order to help those in need. Therefore, government involvement in medical services and care for seniors and others is vital for happy seniors.

1. How does the author develop Paragraph 3?

A．By listing some statistics.

B．By giving examples of lonely people．

C．By pointing out similarities and differences.

D．By comparing different cultures in different countries．

2. What does the underlined word “equivalent” in Paragraph 4 probably mean?

A．Relevant．	B．Opposite．
C．Similar．	D．Superior．

3. What will the Minister of Loneliness do?

A．Do housework for lonely people．

B．Help fund charities to aid lonely people．

C．Communicate with anxious school students．

D．Develop friendships with the elderly．

4. What is the main idea of the text?

A．UK becomes the capital of loneliness．

B．Loneliness affects old people’s life worldwide.

C．Many teenagers suffer from loneliness．

D．UK’s Minister of Loneliness settles loneliness.

10 . Something strange was happening inside Anne' s home. During the summer of 2014, twins Gavin and Garrett, then three, each had skin rash (疹子) that wouldn't go away. 14-year-old J. D. had stomach pains so severe that he couldn’t climb the stairs，but tests found nothing wrong. By winter, the family's health problems were getting worse.

One day, Anne found brown water flowed out of the tap. Worried that the water was polluted, the family began using bottled water for cooking，drinking, and bathing.

In January 2015，the city of Flint sent out a notice stating that the water supply—which had been switched, in a cost-cutting measure, from the Detroit water system to the Flint River the previous spring—contained high levels of trihalomethanes (三卤甲烷). The notice warned that elderly people might be at risk for health problems but emphasized that the water was otherwise safe to drink.

Shocked, the self-claimed "stay-at-home mom turned water warrior" researched the water supply and searched the Internet for information that she distributed to city officials, listing the side effects of exposure to trihalomethanes. Then she urged her neighbors to attend city council meetings, where they shared their health problems. Still, officials insisted the water was safe to drink. So Anne demanded that the city test her water. The results were disturbing. The trihalomethanes were the least of her problems. The tests included that the lead levels in her water were nearly seven times the legal amount.

Anne had her children tested for lead. All the kids showed lead poisoning. She requested Flint's water quality reports and discovered that the city wasn't applying the proper corrosion (腐蚀) control standards to its pipes; the standards prevent the metal in pipes from leaking into the water.

1. How did Gavin suffer from the disease?

A．His stomach hurt so much that he couldn’t' climb the stairs.

B．He had rash on his skin which wouldn’t' disappear.

C．His disease got too ill for him to get any medical tests.

D．He had weak eyesight and couldn't go to school,

2. Why did the city of Flint change its water supply?

A．The Detroit water system had been polluted.

B．The Flint River was made clean a year ago.

C．They wanted to cut the cost of water supply.

D．The Flint River always has brown water.

3. The test of the water from Anne' s home showed that          .

A．her family had the worst of the trihalomethanes pollution

B．the water from her tap was safe to use except for drinking

C．her family was located in the most polluted part of the city

D．there was something more serious than the trihalomethanes

4. The water problem was caused by         

A．the lack of proper corrosion control to the pipes

B．the overuse of water-purifying chemicals

C．the exposure to trihalomethanes in the water

D．the improper use of metal in the pipes
