1 . Chinese President Xi Jinping announced on July 31 that China's BeiDou Navigation Satellite System (BDS) has been completed and has started providing full-scale global services that day.

In the 1990s, Chinese government approved and began research and development of a space-based navigation and positioning system aimed at easing the country's heavy dependence on foreign networks. The system is called "BeiDou". It has planned a three-step strategy for developing the BDS.

The construction of BDS-1, the first step of the strategy, started in 1994 and was completed in 2000. The BDS-2 system started construction in 2004. By 2012,a total of 14 satellites had been launched to complete the deployment(部署)．In November 2017, China launched the first two satellites for the BDS-3 system, which started construction in 2009, and officially expanded its regional navigation system into a global network.

In late June, the final satellite to complete BeiDou's third-generation network was lifted by a Long March 3B carrier rocket. After in-orbit tests over the past month, the satellite recently started its formal operations.

Since 2000, 59 BeiDou satellites, including the first four experimental ones, have been launched from Xichang on 44 Long March 3-series rockets, with some of them having retired.

BeiDou began providing services for civilian users in China and other parts of the Asia-Pacific region in December 2012. At the end of 2018, it started providing basic global services. BeiDou offers accurate positioning, navigation and timing, as well as short messaging communication. The services are used in various fields.

It offers an alternative to Russia's GLONASS and the European Union's Galileo system, as well as the United States' GPS.

The operating of BeiDou's full-scale global services is a significant milestone in China's efforts to boost science and technology and strengthen its space industry. The move is a major contribution to the global public-service infrastructure (基础设施) as well as a remarkable strategic achievement of socialism with Chinese characteristics in the new era.

2 . Claire Wyatt, a 24-year-old British volunteer, led eight Cambodians living with disabilities on a 155-mile bike ride from Phnom Penh, the nation’s capital, to Siem Reap to raise money and deliver supplies to those in need in the coronavirus pandemic(新冠病毒大流行).

“Leading this trip was an incredibly special experience for me,” said Claire. “Not only was I encouraged by the determination of each and every rider, but also the team taught me every day not to focus on their disability.”

When she was first asked to lead the trip, Claire admitted, she was feeling nervous about her team traveling such a distance in just a few days because cycling with a disability can come with added physical and emotional challenges.

One team member named Dy, who lost an arm in an accident, biked using just one arm to balance. Another named Vulta could only pedal on one side due to polio(小儿麻痹). Despite all the difficulties, Claire realized quickly that she didn’t have to worry about her team. She saw them deal with rough area that she had seen abled cyclists give up on before.

The volunteers covered the distance in just four days, not only helping so many people across the country, but also overcoming huge difficulties to get there.

“The best thing about this ride is that the riders have all volunteered their time to do this. They are so enthusiastic about Cambodia and raising money for others in need,” said Claire. “The money raised will feed 99 families in Siem Reap.”

Claire recalled her favorite moment of the experience, when one of the cyclists pushed an exhausted teammate up a hill for 2 miles. “One moment that stood out for me was when Naret, our only female rider, was feeling tired,” she said. “Her fellow rider gently put his hand on her back and pushed her for 2 miles! They were encouraging each other to push through the tiredness.”

1. Why did Claire and eight Cambodians cycle 155 miles?

A．To challenge themselves.	B．To help out needy people.
C．To take part in a competition.	D．To raise money for the disabled.

2. What worried Claire before the ride?

A．She might be injured on the road.	B．She would be unable to lead the team.
C．Her team might be looked down on.	D．Her team couldn’t finish the route.

3. Which of the following can best describe the team?

A．Confident, calm and friendly.	B．Honest, patient and open-minded.
C．Strong-minded, brave and caring.	D．Curious, creative and experienced.

4. What did Claire think of the journey?

A．It could have taken less time.

B．It was amazing and inspiring.

C．It changed her idea about human nature.

D．It was more difficult than she had expected.

4 . The flu season arrives so predictably, and affects so many of us, that it’s hard to believe that scientists have had very little idea why cold weather helps germs to spread.

Worldwide, up to five million people catch the illness each flu season, and around a quarter of a million die from it. Part of its power comes from the fact that the virus changes so quickly that the body is hardly prepared. “The antibodies we’ve built up no longer recognize the virus – so we lose our immunity,” says Jane Metz at the University of Bristol. It also makes it harder to develop effective vaccines, and even if one comes out, governments often fail to persuade enough people to take it up.

The hope is that by understanding better why flu spreads in winter, but naturally fades in summer, doctors could find simple measures to stop its spread.

Previous theories had centred on our behaviour. We spend more time indoors in the winter, meaning that we’re in closer contact with other people who may be carrying germs.

Another popular idea concerned our physiology(生理机制): the cold weather weakens your body’s defenses against infection. In winter, without much sunlight, we may run low on Vitamin D, which helps power the body’s immune system. Moreover, when we breathe in cold air, the blood vessels in our nose shrink, which affects the normal function of white blood cells, allowing viruses to slip past our defenses unnoticed.

While such factors both play some role, analyses suggested another ignored cause may have been lying invisible in the air that we breathe. Thanks to the laws of thermodynamics(空气热力学), cold air can carry less water vapor before it reaches the “dew point” and falls as rain. So while the weather outside may seem wetter, the air itself is drier as it loses the moisture. And researches in the past few years has shown that these dry conditions seem to offer the perfect environment for the flu virus to flourish.

In wetter air, the epidemic struggles to build strength, while in drier conditions it spreads like wildfire. And comparing 30 years’ climate records with health records, Jeffrey Shaman at Columbia University found that flu epidemics almost always followed a drop in air humidity.

1. What can we infer from the second paragraph ?

A．We lose immunity due to the absence of our antibodies.

B．The antibodies fail to function due to variation of virus.

C．Government should come up with better ways to persuade people.

D．One in four of the infected die from the influenza each flu season.

2. What is the purpose of understanding better why flu spreads in winter?

A．To help develop effective vaccine.

B．To seek ways to treat people infected with flu.

C．To figure out ways to cut off its transmission.

D．To explore how to defend our immune system.

3. In what weather condition a flu epidemic is more likely to occur ?

A．Destroying bodies’ immune system.

B．Powering our bodies’ immune system.

C．Killing numerous viruses that we take in.

D．Stopping us acquiring enough Vitamin D.

4. What is the best title of the passage?

C．A predictable flu season	D．Why germs spread in winter
