While some farmers are quick to tell visitors to get off their land, David Walston is doing the opposite. He has donated land on his family farm to create two large community vegetable gardens and invited surrounding villages to get involved.
"I thought the thing I can do fairly uniquely is provide the land and machinery to try to make people's lives better during the lockdown. " Mr Walston, 37, who runs Thriplow Farms, south of Cambridge, said. "The enthusiasm has surprised me a lot, with 114 people from five villages signing up. "
The two 1, 000sqm areas will be open for anyone to help with any job that needs doing. A wide range of vegetables will be grown, including peas, broccoli, sweetcorn, squash, potatoes and leeks. In Mr Walston's scheme, which he has called Coveg, people can do as much or as little as they like and the produce will be shared, and any surplus given to the elderly and NHS workers. None of the produce will be sold and distribution will be only loosely linked to the amount of work done.
He is lending his machinery for the backbreaking work. Farm suppliers are supporting the project, with Kings Seeds and Tozer donating seeds and Howseman Agriculture offering irrigation equipment.
Claire Mackenzie, 47, a doctor from Barrington, has agreed to bring seeds in their own gardens to the community plots. She sees Coveg as a way of connecting local people to the countryside that surrounds them. "We live in an arable area but we often do not know our farmers. This is a brilliant way of pulling people together, " she said. She hopes to get her two teenage sons involved.
Mr Walston's idea has already prompted three local farmers who also want to donate parcels of their land to contact him. They have a corner of land that would be suitable and machinery that would take the backbreaking work out of preparation. They can't wait to offer.
1.Which of the following was unexpected according to Mr Walston？
A.The quality of people's lives.
B.The number of participants.
C.The decision to donate land.
D.The idea to create vegetable plots.
2.How will the vegetables be distributed？
A.On a one-to-one basis.
B.According to the family size.
C.On a first come, first served basis.
D.According to the amount of work done.
3.What is Claire's attitude to vegetable garden project？
A.Skeptical. B.Cautious.
C.Ambiguous. D.Favorable.
4.Which of the following can replace the underlined word "prompted" in Paragraph 6？
A.Inspired. B.Discouraged.
C.Threatened. D.Persuaded.

For over a century, native Asian honeybees have been steadily pushed aside by the European species, which were introduced to China by beekeepers because the female workers are more focused on their job and produce more honey, which is also sweeter.
However, the European species also carries a number of deadly diseases that can damage the natural habitat. Some researchers calculate that up to 80 per cent of China's native honeybee population has been lost since the first European bee farm in the country was established in the late 19th century.
The sweeping expansion of Asia's European honeybee population causes an ecological crisis. After more than 70 million years of evolution, native Asian honeybees could pollinate（对……授粉）a wide range of plant species in the region. However, many Asian bee species across the region are now close to extinction, and that's a cause for concern as the flowers of many Asian plants are not recognised by European honeybees, which will cause fundamental changes in the ecological balance.
A solution put forward by bee scientists was to draw a border between European and Asian honeybees. In some parts of China, bee farms are not allowed to use the European species, giving the native bees some breathing space.
After years of decline, the Eastern honeybees are gaining a foothold, especially in mountains and warm, tropical areas. It is because they can deal with the real hardship of life. The Western honeybees. on the contrary, rely very much on the protection and care of humans. Without caretakers, they have little chance to survive in Asia, where hornets（大黄蜂）alone could wipe them out.
The decline of Asian honeybees was alarming because of their important role in the food chain. Fewer bees mean fewer plants, fewer plants less food and less food fewer humans. We must take positive, sustainable steps towards protecting China's Asian honeybees.
1.What made China's native honeybees endangered？
A.Overdevelopment of the land.
B.Introduction of European bees.
C.Pollution from cars and factories.
D.Lack of a variety of plant species.
2.What can be inferred about many Asian plants from the third paragraph？
A.They will not flower.
B.They might grow slowly.
C.They might not be pollinated.
D.They will harm the environment.
3.What is basically typical of China's honeybees？
A.Sociable.
B.Aggressive.
C.Productive.
D.Adaptable.
4.What is the author's purpose in writing this passage？
A.To analyse influence of European bees.
B.To urge protection of native Asian bees.
C.To suggest ways of limiting European bees.
D.To introduce comeback of native Asian bees.

After at least five years of transporting you around the country, car batteries will now spend their retirement making you tea and toast and running your washing machine.
Used electric car batteries are being changed into home energy storage units which can be linked to rooftop solar panels to keep lights on and devices running when the sun goes down. The plan between Honda and Snam, an Italian energy infrastructure company, will reuse or recycle thousands of batteries from electric and hybrid cars and trucks across Europe, with single batteries installed（安装）in homes and lines of them linked to wind farms to store electricity.
They will also be used by homes and businesses on "time of use" electricity rates—to be charged up when electricity is cheap and used when the rate increases at times of peak demand. The plan will help solve one of the biggest challenges for the rapidly growing electric car industry —how to deal with large batteries which contain valuable metals such as lithium and cobalt but are expensive to break down and recycle.
Most have a warranty（保证）lasting five to eight years depending on how well they are managed and how often recharged. Used batteries have 50 to 90 per cent of their original capacity, according to Aceleron, which makes batteries that are easier to reuse and recycle.
Amrit Chandan, its founder, said："Transport is the largest source of carbon emissions in the UK, and in order to reduce carbon emissions, million electric vehicles are sold each year. But we are currently solving one environmentally friendly issue while ignoring another. Waste is the elephant in the room. By designing batteries for the circular economy from the start, we can prevent mountains of battery waste from being created worldwide. "
1.What can be inferred about used batteries from paragraph 2？
A.They will be taken apart.
B.They will soon disappear.
C.They can be given a second life.
D.They are used to produce electricity.
2.What is the biggest problem facing electric car industry？
A.The solution to battery waste.
B.The production of electric vehicles.
C.The invention of cheap batteries.
D.The creation of fast electric cars.
3.What does the underlined word "they" in paragraph 4 refer to？
A.Used batteries.
B.Cars and trucks.
C.Homes.
D.Hosts.
4.What is the main idea of the text？
A.Battery waste has become a big concern.
B.Transport is responsible for carbon emissions.
C.Used electric car batteries will soon power homes.
D.New reusable battery can get rid of battery waste.

When I was young, I dreamed of becoming many things. Sometimes, I wished I was a astronaut going up into space, finding new planets but jumping around in a cool space suit. Other times, I imagined that being a cowboy in the Wild West, wearing stylish cowboy boots. On other occasions, I pretended to being a famous footballer, using my skills score lots of goals for my favourite team. Growing up with siblings also helps, combining our ideas and putting our thought into action. I was even able to create entirely plots in my head, using nothing more than my brain.
Looked back, I realize the imagination is a wonderful thing in your life.
