【题目】 Over a four-year period, Swiss researchers have developed a machine that can keep human livers ()alive outside of the body for one week.

Livers are among the most commonly transplanted (移植)human organs. Current technology can only keep human livers alive for up to 24 hours. It is reported that, in 2017, about 8.000 liver transplants were performed in the U.S., of which 360 used livers from living givers In addition, about 11,500 people were registered on a waiting list to receive a liver transplant. Keeping livers alive and functioning for longer periods could greatly improve the chances of survival for patients.

The researchers say the purpose of their “Liver4Life” machine is to perform what they call liver perfusion (灌注)operations outside of the human body. Perfusion is the process by which blood or other liquids are pumped through organs and tissue. The machine keeps the liver at the right temperature and moves it in a way that would be natural in the body. Using a pump to fill the liver with blood acting like a human heart, the machine also provides oxygen to the organ, controls red blood cell levels and removes waste.

The research team began their experiments with livers from pigs. After repeated testing and engineering development, they succeeded in getting the pig livers to survive for seven days with support only provided from the Liver4Life machine. They also discovered the system can work to repair damaged livers. The team is now planning its next step to transplant machine-treated organs into patients.

Pierre-Alain Clavien. leader of the research said in a statement. “This technology will greatly increase the number of livers available for transplant, improving the chances of survival for patients. The success of this unique machine opens the way for many new applications in transplantation and cancer medicine.”

1What does the author intend to do in paragraph 2?

A.Introduce a brand new topic for discussion.

B.Provide some latest data about present liver transplants.

C.Show the urgency of tech improvement in liver transplants.

D.Remind readers concerned of the importance of a healthy liver.

2What does the underlined word “it” in paragraph 3 refer to?

A.The machine.B.The liver.

C.The temperature.D.The tissue.

3What can we learn about the Liver4Life machine?

A.It is among the most commonly used machines for liver transplants.

B.It is aimed to carry out liver perfusion operations in the human body.

C.It can perform several functions to keep the liver working normally.

D.It can be used to keep the pig livers alive for more than one week.

Millions of people illegally download movies, music and video games every day, and online piracy is a serious and expensive problem. Recent figures show that 90% of files transferred over file-sharing networks are copyrighted. And it's costing the US economy up to $250 billion a year. At the heart of the matter there's a moral question to consider. Is it fair that someone downloads for free in seconds something that took a team of people months of hard work to create?

What are governments doing about online piracy? Some countries have passed tough new laws. The Spanish government has shut down domestic file-sharing websites and blocked access to overseas-based sites. Also, governments are going after high-profile pirates. Kim Dotcom, the owner of Megaupload.com, was arrested in New Zealand, who has been accused of piracy because many people were using his website to swap copyrighted files.

Are laws and arrests really the best way? Many people aren't so sure. The problem is that films are released at different times around the world. Kim Dotcom says that a teenager in Germany, for example, has to wait six months to see a movie that has already come out in the U.S. So, instead of waiting, they download it illegally. Kim says, 'If everybody had access to content at the same time, you wouldn't have a piracy problem. '

American company Netflix lets users stream films to their TV. But many complain that Netflix's selection of movies is too small and that there aren't enough new releases. One reason is that studios release films on DVD and then, after a few months, make them available for streaming. But what actually happens is one person buys the DVD, they upload it to a file-sharing site and everyone else downloads it for free.

American law student Srikant believes that if movie studios and record companies want to beat the pirates, they need to make it just as simple and quick to get content legally. 'I think people would pay for content if it's reasonably priced and it's available when they want it. ' he adds.

This is already happening with music. Spotify is a program that lets you stream music to your computer for just 5 per month. And since it was launched in Sweden in 2009, online music piracy in Sweden has dropped by 25%. The key to its success lies in that Spotify has a large range of music; songs are instantly available and the service is reasonably priced.

Easy access isn't the only possible solution. Economist Glenn MacDonald thinks he has the answer. He says record companies should give albums away for free and then make money from tours and merchandising. That's not such a ridiculous idea. The heavy metal group Manowar has made a fortune from their tours, which are full of fans who discovered the band by illegally downloading the music.

Online piracy is a complex and controversial issue. And one thing is for sure: it's not going away anytime soon .

【题目】 Algorithms (算法) affect nearly every part of a person's experience on the Internet. Search engines are most people' s entry to the Internet.If a person wants to find information about something, they usually start with a search bar.As soon as they start typing or choosing links,the algorithm starts gathering data about every choice users make and uses that data to try to find the websites or information that most directly relate to what the user is looking for.

The problem with algorithm is that they can limit the kinds of information people see,says MacMillan,a reading researcher with Project Information Literacy (能力). He argues this can be harmful to people's critical thinking and lead them to believe that only one point of view is correct.

Companies also pay to post advertisements for products that could relate to users' search data. For example,if you search for places to take a vacation,you will likely start to see ads for travel companies, flights or hotels.

Renee Hobbs, director of the Media Education Lab at the University of Rhode Island, however, argues that algorithms are not all bad. She says search engine algorithms can help you find what might be the most useful information faster. But she says it is in the interests of Internet companies to keep users on the Internet for as long as possible so they see more ads.

The current generation of young people grow up using the Internet and they are prone(易于遭受) to distrustful information.That is why schools must train students how to use the Internet more wisely in their Studies.It is the duty of education to keep students informed about the world around them. Yet it is not the duty of education alone. And lawmakers should consider increasing data protection rules. Individuals can also use a wide variety of websites to avoid algorithmic controls.

1How do algorithms affect users' Internet experience?

A.They lead to slower Internet connection.

B.They block ads for users automatically.

C.They always help users get reliable links.

D.They determine the content users receive.

2What is Hobbs' attitude to algorithms?

A.Doubtful.B.Supportive.

C.Objective.D.Indifferent.

3What can be concluded from the last paragraph?

A.Young people fall victim to the Internet.

B.Data protection rules are already enough.

C.Education is fully responsible for algorithmic controls.

D.Joint efforts are needed to handle algorithmic controls.

4Which column of a magazine is the text most likely from?

A.Science.B.Entertainment.

【题目】 Carol Lee Lindner climbed into the 40-foot boat tied to the Fairmount Boathouse dock, and gave the new members their first lesson in the ancient sport of dragon boating.

The 25 women, aged 29 to 65, watched their coach carefully. All had breast cancer and survived. Their decision to join the Philadelphia Women's Dragon Boat Team was brave and crazy.

Over the months of training, one would be told that cancer had spread to her bones and another would be hospitalized for radiation treatment side effects. But these strong and determined womeneach and every one of themtook part in the International Dragon Boat Racing Championship.

In theory, it's a terrible sport for women whose muscles and nerves have been damaged. Doctors generally advised them to avoid hard and repetitive arm exercise. But seven years ago, Canadian Donald Mckenzie, a sports medicine physician, showed dragon boating is good for survivors. “It builds both their physical and mental strength.” Mckenzie said.

Coach Lindner, 60, was inspired by that and included the 25 women in her three-year-old Philadelphia Women's Dragon Boat Team.

The survivors tried hard and did their best. No self-pity.

Renata Whitaker, her hair growing back, began feeling more confident. But she grew tired and easily got out of breath. She had to be in hospital for a week. As she got better she called Lindner, saying she had got well enough to be in the game. Lindner told her if she felt up to it, she would be with the team.

“But you are not going to paddle,” Lindner said, “Remember what I said, “To be strong, fit women for life. I want you by my side for the rest of our lives, not just for one race.”

These women tested their limits. A 500-meter race lasted about three minutes.

As the city darkened in the heat, the team finally paddled toward the Fairmount Boathouse.

Soon, the river was filled with the sounds of painful but happy women singing Merrily We Roll Along.

1What do the twenty-five women have in common?

A.They are crazy about dragon boating

B.They are cancer survivors.

C.They were inspired by Donald Mckenzie and have trained together for three years

D.They have broken the record of the International Dragon Boat Racing Championships

2Why did Lindner refuse Whitaker's request?

A.Because Whitaker wasn’t really good at paddling.

B.Because Whitaker easily got tired and out of breath.

C.Because Whitaker hadn't recovered completely.

D.Because a new paddler would be in Whitaker's place.

3Which of the following will Mckenzie support?

A.Dragon boating will help repair patients' damaged nerves

B.Patients should feel sorry for themselves if they don t take part in dragon boat races

C.Dragon boating will benefit the patients physically and mentally

D.Cancer survivors should avoid hard and repetitive arm exercise

4What can we know about Lindner?

A.She enjoys the sport of boat racingB.She is tough with her team members

C.She is also a cancer survivor.D.She is helpful and inspiring.

【题目】 Austin residents and businesses are making efforts to put their leftovers to good use. The city is among a handful of U.S.cities aiming for “zero waste”.

For Austin, there are plenty to go around: it annually wastes more than 190 million pounds of food, worth at least $200 million. Those numbers are big, but they're not out of line with national trends-some 40 percent of food in the nation goes to waste. Put in plain terms, that is enough to fill a 90,000-seat stadium each day.

For many, the answer lies in donation. Austin City Limits, one of the city’s influential festivals, gives all unwanted food to the Central Texas Food Bank. And there are volunteer-driven nonprofits that pick up donated food and deliver it to hungry people.

But the best practice, Austin believes, is to use less, and the city is calling on businesses and households to buy the right amount of food. Full Fridge, a new meal-delivery service, solves this problem. “Full Fridge came about because, basically, we were seeing a lot of people not knowing how to prepare food,” says co-founder Mokshika Sharma. They would buy groceries, but not know what to do with them, and end up throwing away a lot.

Her business hopes to end that problem by offering ready-made meals for only five dollars each. Full Fridge also minimizes waste by stopping sales two days before delivery, so the chef and shopper can plan precisely.

Another satisfactory solution is to compost(......制成堆肥) it. Austin’s restaurants and grocery stores typically contract with composting companies to deal with much of their food waste, and then sell it as fertilizer. Meanwhile, Compost Pedallers, a company created by Dustin Fedako, is working on bicycle-powered compost collection.

We play the dot-connecter,” says Fedako, “getting the material from those of us who are making it to the people in the community who use it as a resource to grow more food, and to grow better quality food.”

1What do the figures in Paragraph 2 indicate?

A.The urgent need for donated food.B.The rapid growth in food donation.

C.The ambitious goal of “zero waste”.D.The serious problem of food waste.

2Paragraph 3 mainly talks about Austin' s efforts to______.

A.feed the hungry.B.make use of leftovers.

C.build more volunteer-driven nonprofits.D.hold festivals to entertain its residents.

3Who are Full Fridge's target customers?

A.Those with too little food.B.Those with poor cooking skills.

C.Those with unhealthy eating habits.D.Those with little time to buy groceries.

4What does Fedako mean by saying “We play the dot-connecter”?

A.They find it rather easy to collect food waste.

B.They hope people will buy better quality food.

C.They link food waste producers to fertilizer users.

D.They are trying to connect with composting companies.
