Explore the villages around Hartbridge
Many visitors came to Hartbridge to see wonderful art galleries, museums and fantastic parks. This brochure will tell you what you can see if you take a short bus ride out of the city.
Camberwell
The historic village of Camberwell was once the home of the wealthy Hugo family, who lived in a huge country house, Camberwell Court, and owned all the land in the area. You can spend a whole day walking around the house and gardens and there is a small exhibition about the family, a children's play area, a gift shop and a restaurant.
Hidcot
Hidcot is situated on the river Owell. Visitors should go to the Nature Park to the south of the village, where there are large numbers of rare birds and flowers. In Hidcot, you can take a two-hour river cruise to see the countryside and learn about the local wildlife from a guide, or hire a boat and explore the river at your leisure.
Tatterbridge
The village was home of the children's writer Jane Potter, whose stories of Benjamin Bear are loved by adults and children around the world. Jane Potter’s home is now a museum and is well worth a visit just for its wonderful gardens. Lovers of Jane Potter’s books should also walk to the Green Valley woods, which have not changed since Jane Potter wrote her stories there 100 years ago.

If you like to spend your time up to your elbows in dirt and have the ability to grow plants that don't wither and die, you may have been told you have a green thumb. This is not a medical emergency, but a slang term meant to show one's natural talent for gardening. But where did the phrase come from?
Both green thumb and green fingers have been common expressions in England and the United States for well over a century, with the Oxford English Dictionary citing use of green fingers as early as 1906 from the novel The Misses make-believe by Mary Stuart Boyd. Green thumb, meanwhile, was used first in 1937 Ironwood Daily Globe newspaper article, which described the phrase as gardening slang.
There are several stories about its origins. Some believe it is a result of growing potted plants, which can often have green algae(藻)on the underside that coat hands. Others point to a story about King Edward I and his love of green peas, which were shelled by subservient workers—one would be honoured for doing the most work and having the greenest thumb. There is also the fact that plants contain chorophyll (叶绿素) which can easily discolour your hands.
However the phrase was cultivated, we have a pretty good idea of how it caught on. In the 1940s, wartime Britain enjoyed a popular gardening radio show titled In Your Garden hosted by C.H. Middleton that made use of both green thumb and green fingers.
Why, then, is the phrase focused more on the thumb when all of your fingers are likely to get discoloured? It might have something to do with an old English proverb: "An honest miller (磨坊主) has a golden thumb." The quality of corn flour could be judged by rubbing it between the forefinger and thumb. Mixed together in the collective consciousness, these two expressions may have resulted in the green thumb we hear about today.
【1】What can we learn about the two slang terms from paragraph 2?
A.They have different meanings at first.
B.Green thumb was preferred by Americans.
C.They were first included in English dictionaries.
D.Green fingers appeared earlier in written history.
【2】The stories about the sources of green thumb are all related to .
A.chlorophyll in plants
B.King Edward I's hobby
C.the green algae that grow on pots
D.King Edward I's skilled gardeners
【3】Why is "thumb" used in the slang "green thumb" rather than other fingers?
A.The thumb is raised to show praise.
B."Thumb" is often used in English sayings.
C.People connect the phrase with the "golden thumb".
D.People think other fingers are useless in gardening.
【4】What is the best title for the text?
A.How did "green thumb" come to English?
B.Why do westerners prefer the finger "thumb"?
C.Why are gardeners said to have a "green thumb"?
D.Is there a relationship between "green thumb" and "thumb"?

Galapagos Giant tortoises (巨型陆龟), sometimes called Gardeners of the Galapagos, are creatures of habit. In the cold dry season, the highlands of the volcanoes are covered in cloud which allows plants to grow despite the absence of rain. In the lower areas, however, plants are not available all year round. Adult tortoises thus spend the dry season in the higher areas, and go back to the lower, relatively warmer areas where there are plentiful eatable plants when the rainy season begins. The tortoises often take the same migration routes over many years in order to find perfect plants and temperatures. The timing of this migration is important for keeping their energy levels high.
Researchers used GPS to track the timing and patterns of tortoise migration over many years. They expected the migration to be timed with current environmental conditions because many other migratory animals do it that way. However, tortoise migration is weakly related to current conditions such as rain and temperature. It is unclear at this point whether they are basing their migration decisions on memories of past conditions or if they are simply incorrectly assessing current local conditions.
Luckily, probably because of their long lives of up to 100 years and large body size, bad timing of migration has smaller effects on giant tortoises compared to small, short-lived animals. Giant tortoises can go up to a year without eating and survive, while other migratory animals might eat more often to keep their energy levels high.
Giant tortoises are important ecosystem engineers in the Galapagos, and their migration is key to the survival of many plants. How the difference in tortoises' migration time will affect the rest of the ecosystem is still unclear. It is quite possible that the mistiming of migration will keep increasing in the future. "One concern is that at some point in the future," says Bastille-Rousseau, lead author of the study, "migration may not be a perfect strategy for tortoises. There may be a reduction in the number of tortoises doing these long travels. This would likely have great effects on the whole ecosystem."
【1】What do we know about Galapagos giant tortoises?
A.They prefer low temperatures.
B.They like living in the highlands.
C.They always hate the rainy season.
D.They seldom change migration routes.
【2】What have researchers found out about the timing of giant tortoise migration?
A.The weather has much to do with it.
B.It disagrees with current conditions.
C.The research has strong effects on it.
D.It is decided by the tortoises' memories.
【3】What might help giant tortoises survive the migration at the wrong time?
A.Their restless energy. B.Their different body shape.
C.Their habit of eating healthily. D.Their ability to go without food.
【4】What can we infer from Bastille-Rousseau's words?
A.Migration is the only choice for giant tortoises in the future.
B.Damage to the ecosystem will reduce the number of giant tortoises.
C.Giant tortoise migration plays a major role in Galapagos’ ecosystem.
D.Giant tortoises protect the ecosystem by their different migration time.

Artificial Intelligence (AI) advice is as influential as humans', but positive crowd views still overpower.
In a study, researchers found that machines that make recommendations-or AI experts-were as influential as human experts when the AI experts recommended which photo users should add to their online business profiles. However, both AI and human experts failed to budge them if their feedback was negative and went against popular views among other users, said S. Shyam Sundar, a professor of Media Effects.
Because people are increasingly using social media to look for feedback, studies suggest that expert opinions and the bandwagon effect (从众效应) may be important factors in influencing decisions. According to Jinping Wang, a doctoral candidate in mass communication and first author of the study. "Nowadays, we often turn to online platforms for opinions from other people-like our peers and experts-before making a decision," said Wang. AI experts are often less expensive than human experts and they can also work 24 hours a day, which, Wang suggests, might make them appealing to online businesses.
The researchers also found that the AI's group status (群体地位) -in this case, national origin was pointed out-did not seem to affect a person's acceptance of its recommendation. Among human experts, however, an expert from a similar national origin who offered a negative opinion of a photograph tended to be more influential than a human expert from an unknown country who offered a similar negative rating of a photograph.
While findings that suggest group status may not affect whether a person values the view of AI experts sound like good news, Sundar suggests that the same cultural biases (偏见) might still be at work in AI experts for they could be hidden in the programming and training data.
"It can be both good-and bad-because it all depends on what you feed AI, " said Sundar. "While it is good to believe in AI's ability to transcend (超越) cultural biases, we have to keep in mind that if you train the AI on pictures from one culture, they could give misleading recommendations on pictures meant for use in other cultural contexts."
【1】What do the underlined words "budge them" in paragraph 2 mean?
A.Raise their spirits. B.Satisfy their needs.
C.Change their ideas. D.Fire their imagination.
【2】Why do users often turn to AI experts?
A.AI experts are more knowledgeable.
B.AI experts are on hand and cost less.
C.AI experts are less influenced by feelings.
D.AI experts are so new as to be more attractive.
【3】Which expert's negative assessments is a person more likely to believe?
A.An expert who has great achievements in arts.
B.An expert with better personality and attitude.
C.A foreign expert who is very popular worldwide.
D.An expert from countries with similar cultures to his.
【4】What did Sundar mean by the last paragraph?
A.People should have a mind of their own.
B.People should be able to tell good from bad.
C.People should know AI's hidden cultural biases.
D.People should be trained how to use AI properly.

Doctors have successfully kept a heart beating in a container for 24 hours, bringing hope to thousands of patients across the world in need of a life-saving transplant.
【1】 However, the "game-changing" device can preserve a heart up to six times longer than existing methods. It provides the heart with oxygen and vital nutrients, allowing more time to transport it.
The device, named ULiSSES, fits into a carry-on box, so hearts can be flown around the world. 【2】 And it is expected to cost under $ 100,000. University of Texas researchers have successfully tested on pig hearts, which are similar to ours.【3】
Dr. Rafael Veraza presented the findings on pig hearts at the annual meeting of the American Association for the Advancement of Science in Seattle.
"【4】 Many years later, it is done much the same way," Dr. Veraza said. "Donated hearts generally remain viable (可存活的) for around four hours using traditional preservation methods.【5】 Being able to keep a heart viable for 24 hours means you could transport it almost anywhere in the world, and this could save many lives."
A.It is expected to come into use soon.
B.The extra time could bring more hope to patients.
C.Usually, a donated heart can only last about four hours.
D.It works without being affected by temperature or air pressure.
E.The pig hearts remained viable for 24 hours after they were removed.
F.The first heart was transported more than 50 years ago by putting it on ice.
G.They plan to test it on human hearts in three months and put it on the market within a year.
