When I first catch sight of Greta Thunberg, it is eight in the morning, and a small crowd has already gathered. It is a Friday, her day of protest, and the 16-year-old is standing outside the parliament(议会) building, next to a sign saying “School strike for climate” in Swedish.

This is the 26th week of her protest, which has taken place every Friday since school started last August. Her goal is to bring Sweden in line with the 2016 Paris Agreement, which promises to limit global warming to below 2℃, compared with pre-industrial levels.

Over the past six months, Greta has rocketed to a level of fame and influence that pretty much nobody, including herself, expected. Her protest was quickly highlighted by the media. Then came a TED talk and an invitation to address last December’s U.N. climate talks in Poland.

While Greta may seem an unlikely climate activist, it was not entirely accidental that she became one. Like many children, Greta watched educational films about the melting Arctic and the fate of the polar bears and the marine mammals bloated (肿胀) with plastic. But unlike other children, she couldn’t let them go. “I became very affected. I began thinking about it all the time.” said Greta.

Greta began researching climate change and has been staying on the topic for six years. She has stopped eating meat and buying anything that isn’t necessary. In 2015, Greta stopped flying on airplanes, and a year later, her mother followed her example, giving up an international performing career. The family has started growing their own vegetables on his own garden outside the city. To meet me in central Stockholm, Greta and her father rode their bikes for about half an hour, although the family has an electric car that they use only when necessary.

1.What can be inferred from the second paragraph?

A.Industry in Sweden is developing too fast.

B.School climate education remains to be improved.

C.The climate around the world has increased by 2℃.

D.Sweden should do more to meet the Paris Agreement.

2.Why did Greta become the focus of media attention?

A.She was expected to be famous.

B.She was invited to the TED talk.

C.She skipped school for the protest.

D.She was active in the protest as a child.

3.What makes Greta devoted to climate activities?

A.The educational programs.

B.Her speech at U.N. climate talks.

C.Her great concern about climate change.

D.The protest of “School strike for climate”

4.What happened after Greta became a climate activist?

A.She moved to the countryside.

B.She had an eco-friendly life.

C.She followed her mother’s example.

D.She gave up her work for her research.

Britain’s seed bank, the only one in the world aiming to collect all of the planet’s wild plant species, has reached its goal of banking 10 percent by 2010.

The Millennium Seed Bank Project, run by Kew Gardens—one of the oldest botanical gardens—will officially deposit the 24,200th species on Thursday, a pink, wild banana from China.

More than 50 countries are now on board with Kew's giant task but vast places of the globe, including India and Brazil, still need to join in and donate seeds, director Paul Smith said.

The seed bank is one of the largest and most diverse in the world with more than 1.5 billion seeds. Its goal is to help protect the planet’s bio-diversity during a time of climate change.

The wild banana seed is under threat of extinction(灭绝) in southwest China from agricultural development. It is a vital food source for Asian elephants and important for growing bananas for human consumption.

Stored at minus-20 degrees centigrade, so they can last for thousands of years, the seeds await the day that scientists hope never comes—when the species no longer exist in the wild.

It is a race against time, Smith said, because in the last decade alone, 20 plants held in the bank have already been wiped out in the wild. He estimates that between a third and a quarter will become extinct this century.

"It is urgent and it is happening now. An area, the size of England, is cleared of primary vegetation（植被）every year." Smith said.

Because most of the world's food and medicines come from nature, protecting wild plant species is quite important, scientists say. There are already many other seed banks safeguarding food crops, which only account for 0.6 percent of plant diversity.

For Kew's next goal—to collect a quarter of wild varieties by 2020—the botanists need 10 million pounds a year, or a further 100 million pounds on top of the 40 million they have already been granted.

1.What’s the final purpose of the Britain’s seed bank?

A. To collect enough money for the project.  B. To safeguard food crops.

C. To protect wild plants from extinction.        D. To help scientists study wild plants.

2.The wild banana seed in China is in danger because of _______.

A. the expanding of farming work           B. the climate change in this area

C. the large number of Asian elephants       D. human’s large consumption

3. We can learn from the passage that _______.

A. the seeds in the bank can be used now and then all over the world

B. India and Brazil haven’t joined in the Seed Bank Project at present

C. there is only one seed bank in the world at present

D. the wild plants in places like India and China will never die out

4. What does the underlined word “it” in paragraph 7 refer to?

A. The extinction of plant species.           B. The Millennium Seed Bank Project.

C. Britain’s seed bank.                      D. Kew Gardens’ next goal.

5.Which of the following information isn’t mentioned in the passage?

A. The global partnership of collecting wild plant species.

B. The temperature condition of the conservative wild plant species.

C. The government’s financial support for the seed bank project.

D. Scientists’ concern on the extinct wild plant species.

阅读下面短文，根据所读内容在表格中的空白处填入恰当的词。

注意：每个空格只填一个单词。

Fruit also makes up a flowering plant. It carries the seeds . The purpose of fruit is to protect a plant’s seeds and help them get spread about. Wind and water spread seeds .So do animals when they eat fruit and drop the seeds .

There are two main types of fruit: fleshy and dry. Fleshy fruits are soft and juicy , the way we usually think of fruits . Peaches ,plums ,and apples are all fleshy fruits . Dry fruits are thin and hard . Grains like wheat and rice , or nuts are dry fruits.

You’ve eaten seedless oranges and grapes . How can they be fruits? It’s because people have changed the way they grow fruit. They can now grow seedless fruit . Seedless fruit comes from special plants called hybrids(杂交生物体) . A hybrid is made by combining two varieties of a fruit to form a new variety . This hybrid grows and produces seeds . But the plants grown from these seeds are seedless . These plants cannot reproduce themselves.

A tomato is a vegetable , right? No , it’s actually a fruit . Other food we think of as vegetables—such as squash , peppers ,and eggplant—also are fruit . They’re fruit because they carry seeds and develop from flowers . Here’s another surprise . Scientists classify the tomato as a berry(浆果) . In addition , they don’t consider some fruits we call berries to be true berries because a berry is normally a type of fruit with a lot of seeds inside it . Technically , a strawberry , isn’t a berry , because it has its seeds on the outside . The red part is just the tip of the strawberry stem that’s enlarged.

Fruits are a source of nourishing(滋养) substances that keep us alive and healthy . For example , they contain many vitamins , especially vitamins A and C, and many minerals . They also provide fibre for a healthy digestive system and carbohydrates that the body needs to make energy.
