1 . After years of heated debate, gray wolves were reintroduced to Yellowstone National Park. Fourteen wolves were caught in Canada and transported to the park. By last year, the Yellowstone wolf population had grown to more than 170 wolves.

Gray wolves once were seen here and there in the Yellowstone area and much of the continental United States, but they were gradually displaced by human development. By the 1920s, wolves had practically disappeared from the Yellowstone area. They went farther north into the deep forests of Canada, where there were fewer humans around.

The disappearance of the wolves had many unexpected results. Deer and elk populations — major food sources (来源) for the wolf — grew rapidly. These animals consumed large amounts of vegetation (植被), which reduced plant diversity in the park. In the absence of wolves, coyote populations also grew quickly. The coyotes killed a large percentage of the park’s red foxes, and completely drove away the park’s beavers.

As early as 1966, biologists asked the government to consider reintroducing wolves to Yellowstone Park. They hoped that wolves would be able to control the elk and coyote problems. Many farmers opposed the plan because they feared that wolves would kill their farm animals or pets.

The government spent nearly 30 years coming up with a plan to reintroduce the wolvers. The U.S. Fish and Wildlife Service carefully monitors and manages the wolf packs in Yellowstone. Today, the debate continues over how well the gray wolf is fitting in at Yellowstone. Elk, deer, and coyote populations are down, while beavers and red foxes have made a comeback. The Yellowstone wolf project has been a valuable experiment to help biologists decide whether to reintroduce wolves to other parts of the country as well.

2 . What are scientists?They are often described as gray-haired white-coated dull scholars.

But the world has changed.Young scientists are making their voices heard and releasing their powers on the world stage.

This is also true in China.Rising stars include new materials expert Gong Yongji,university professor Liu Mingzhen,and biologist Wan Ruixue.At the age of 28 in 2018,Wan Ruixue received the 2018 Science & SciLifeLab Prize for Young Scientists.This is a global prize to reward outstanding scientists at an early stage of their careers.

She focuses mainly on biomedicine (生物医学) and artificial intelligence.“Both are cutting-edge (前沿) technologies at an early stage of development,” she said.

“So,I think they have great potential to be developed.I think in the study of cutting-edge technologies,China and other leading countries in the world are standing on the same starting line.And in the study of structural biology,China is likely to become the leader.”

She felt it was her fate to become a biologist.“I grew interested in the natural world,when I was very young,” she said.In 2009,she entered Sun Yat-sen University.

In her third year at the university,she realized that she wanted to do something related to biomedicine.So she emailed China’s top biologist Shi Yigong,hoping to join his lab at Tsinghua University.

Shi recognised her talent and welcomed her.Years of efforts at the lab have paid off.Her research on the high-definition 3D structure of spliceosome led to a scientific breakthrough.

Unlike many of other young scientists who choose to pursue further study abroad,Wan currently has no plan to go overseas.

“The whole ecosystem for scientific research is continually improving in China,” she said,adding that the country has great science facilities.

1. What does the underlined word “releasing” in paragraph 2 mean?

C．Her contribution has been recognised.

D．She thinks it’s boring but worth trying.

4. Which can be the best title of the text?

10 . 2050 seems a long way away, but it is not impossible to predict the future though. With the speed we are moving now so many amazing things are going to happen in the future. So where is technology going in the future?     1    .

◇The Internet will be free for everyone.

The Internet is really a key driver these days. But it is not free for everyone yet. There have already been attempts like Facebook’s Free Basics.     2    , there is a very strong possibility that the Internet will be free for everyone in the future.

◇Personal airplanes will be used widely for short journeys.

With the increasing population, it is not very hard to predict that common methods of transportation will not be enough.     3    , so in this case personal airplanes will be a handy method of transportation for common people. Of course, there will be proper air traffic control for these personal airplanes.

◇Most cancers will be treated successfully.

    4    . It will be a huge achievement in the history of medical science. Many studies are already showing a trend (趋势) towards this.

◇    5     .

There will be great achievements in space research. In the year 2050, humans will be able to live on Mars. We will receive more intelligent signals from space. Chances are we will be able to find the next Earth — like planet.

A．Though it hasn’t happened yet

B．Let’s start our predictions

C．The world’s population will cross 9. 6 billion

D．What do you think of my predictions of 2050

E．Humans will live on other planets

F．There will be much heavier traffic on the road

G．The number of deaths caused by cancers will be greatly reduced
