Compared with solar and wind energy, which are booming, tidal (潮汐的) power is a loser in the clean-energy competition. But if you did want to build a tidal power station, there are few better sites than the mouth of the River Severn, in Britain. Its tidal range, the difference in depth between high and low tides, of around 15 metres is among the largest in the world.

Engineers and governments have been toying with the idea since at least 1925. But none of the suggested projects has materialised. Price is one objection. A study thought that tidal energy might cost between ￡216 and ￡368 ($306-521) per MWh of electricity by 2025, compared with ￡58-75 for seagoing wind turbines (轮机) and ￡55-76 for solar panels. Environmentalists also worry that any plant would change the tides, making life harder for wildlife.

An engineer called Rod Rainey thinks he has a way around both problems. He plans to replace the conventional turbines of previous plans with a much older technology. Specifically, he plans to span (横跨) the river mouth with a line of water wheels. This is a design that dates back to the early days of the Industrial Revolution. Examples can be found fixed to the sides of old watermills (水磨).

But there would be nothing old-fashioned about Mr Rainey’s wheels. Thirty metres high and sixty wide, they would be made from ordinary steel. Two hundred and fifty of them, along with the supporting structures, would be floated into place and secured to the seabed, creating a line 15km long. Together, they could supply power at an avenge ate of 4GW. That is about as much as two biggish nuclear power stations would manage. Substituting one of the wheels with a set of locks would provide a shipping channel about twice the width of Panama Canal, permitting upstream ports such as Avonmouth and Cardiff to continue operating.

1.What is special about the mouth of the River Seven?

A.The tidal range there is about 15 meters.

B.It has the largest tidal range in the world.

C.The tidal power station has been built there.

D.Its power plant makes life harder for wildlife.

2.What was people’s initial attitude towards tidal power?

A.Opposed. B.Supportive.

C.Controversial. D.Doubtful.

3.What are the locks used for?

A.Support. B.Transportation.

C.Securing wheels. D.Producing electricity.

4.What’s the best tittle for the text?

A.Rainey invented turbines.

B.Rainey’s tidal power station.

C.Tidal power in the River Seven.

D.An old idea might be made practical.

What is a hero? We may think of the fictional characters with supernatural powers or great people who can influence world events. Now, as the nation continues its all-out efforts to fight against the novel coronavirus pneumonia(COVID-19), medical staff have become heroes in the eyes of the public.

As of Feb 19, a total of 32,000 medical staff outside Hubei province have been working to treat patients around the center of the outbreak.

Zhang Dingyu, the president of Wuhan Jinyintan Hospital, is one of these heroes. Since the hospital received the first seven patients in December, Zhang has been so busy that he barely gets any sleep. Even suffering from amyotrophic lateral sclerosis (肌萎缩侧索硬化), the 56-year-old doctor is doing his best to quicken his pace to save precious time for infected patients. “I have to run, racing against time to save more patients from the deadly disease, because I don’t have much time left in my life,” Zhang told Xinhua News Agency.

With the duty of saving lives, many medical professionals like Zhang have been working long hours for days, despite their fear and worries.

Lu Jingjing from Wuhan Children’s Hospital also works at a temporary mobile hospital. She does not let her parents know that she is now working with novel coronavirus-infected patients.

When her parents ask for a video chat, Lu says she is working and lets her husband and children chat with them instead.

“It’s dangerous but we should win the battle with the virus as soon as possible, so that medical staff and patients can go back home,” she told China Daily.

US writer Khalil Gibran (1883-1931) once wrote, “Tenderness and kindness are not signs of weakness and despair, but the manifestations of strength and resolution.” It’s true for the medical workers.

Everyone has fear, especially when it comes to deadly diseases. But for medical staff, saving lives comes first and is enough for them to be brave and stay on the front. They may look like ordinary people in daily life, but in these extraordinary times, they are heroes.

1.What is the author’s main purpose in writing this article?

A.To explain what makes a modern-day hero.

B.To praise medical staff for their efforts to fight the NCP.

C.To describe what measures China has taken to deal with the virus.

D.To show the difficulties faced by medical staff treating NCP patients.

2.What do we learn from Zhang Dingyu’s words?

A.His illness has turned him into an impatient man.

B.His illness makes him work without fear.

C.He feels sorry for himself because of his illness.

D.He wants to help as many patients as possible.

3.Why doesn’t Lu Jingjing answer her parents’ video calls?

A.She is too busy and has no time for video chats.

B.She doesn’t want her parents to worry about her.

C.It’s not allowed to make a video call from the hospital.

D.There is no WiFi signal at the temporary mobile hospital.

4.The underlined word “manifestations” in the second-to-last paragraph probably means “_______”.

A.results B.differences

C.indications D.advantages

Researchers found that compared with teens who spent much of their free time in front of TV sets, those who were physically active often had higher self-respect, better grades and were less likely to have risky behavior like taking drugs, smoking, or drinking．The findings, based on a national survey of nearly 12,000 middle and high school students, were published in a journal．

"Across the board, children who engaged in any kind of activity were belier off than kids who watched a lot of TV," said study co author professor Penny Gordon Larsen of the University of North Carolina．

Other studies have linked certain content of television programs, such as violence and sex, to children's behavior．But beyond this issue, Gordon-Larsen said that kids who spend hours watching TV "miss opportunities" to develop skills, learn teamwork and have other experiences that their more active peers benefit from．

That doesn't mean, however, that kids have to be on the football team． The study found that some activities like skating and skateboarding——which adults sometimes frown upon——were also related to better self respect and less risk taking．

That skaters were better behaved than TV watchers might come as a surprise to some adults who consider these teens to be bad, according to Gordon-Larsen．Skateboarding is forbidden in many public areas, and some communities oppose building skating parks．But if kids who like to skate have nowhere to do it, "it's a shame," said Gordon-Larsen．

Not only should parents encourage their kids to engage iii the physical activities they enjoy, she said, but schools and communities should also do more to create opportunities for children to be active．

1.From the passage we know that          .

A．physically active kids get into less trouble

B．more skating parks are being built

C．kids who spend hours watching TV benefit a lot

D．kids who have nowhere to skate tend to take drugs

A．get into the habit of smoking or drinking

3.This passage is mainly written to ___      ．

A．offer some information to teachers and parents

B．persuade kids not to watch a lot of TV

C．urge the public to help children be active

D．show the author's concern about children's growth

4.What does the underlined sentence "which adults sometimes frown upon" in the 4th paragraph mean?

A．Some adults don't understand the sports．

B．Some adults are impatient with kids．

C．Adults consider it dangerous to go skating or skateboarding.

D．Some adults think them related to bad behaviors.

5.It can be inferred from the passage that          .

A．kids are not expected to be active by some parents
