A rainforest is an area covered by tall trees with the total high rainfall spreading(扩大) quite equally through the year and the temperature rarely falling below 16°C. Rainforests have a great influence on the world environment because they can take in heat from the sun and adjust the climate.

Without the forest cover, these areas would reflect(反射)more heat into the atmosphere, warming the rest of the world. Losing the rainforests may also influence wind and rainfall patterns,potentially(潜 在地) causing certain natural disasters all over the world.

In the past hundred years, humans have begun destroying rainforests in search of three major resources : land for crops, wood for paper and other products, land for raising farm animals. This action affects the environment as a whole. For example, a lot of carbon dioxide in the air comes from burning the rainforests. People obviously have a need for the resources we gain from cutting trees but we will suffer much more than we will benefit.

There are two main reasons for this. Firstly, when people cut down trees, generally they can only use the land for a year or two. Secondly, cutting large sections of rainforests may provide a good supply of wood right now, but in the long run it actually reduces the world’s wood supply. Rainforests are often called the world's drugstore. More than 25% of the medicines we use today come from plants in rainforests. However, fewer than 1% of rainforest plants have been examined for their medical value. It is extremely likely that our best chance to cure diseases lies somewhere in the world’s shrinking(减 少)rainforests.

1. Rainforests can help to adjust the climate because they______.
A.reflect more heat into the atmosphere
B.bring about high rainfall throughout the world
C.rarely cause the temperature to drop lower than 16°C
D.absorb(吸收) the heat from the sun, reducing the effect of heat from the sun on the earth
2. What does the underlined word “this” in the third paragraph refer to?
A.We will lose much more than we can gain.B.Humans have begun destroying rainforests.
C.People have a strong desire for resources.D.Much carbon dioxide (二氧化碳)comes from burning rainforests.
3. It can be inferred from the text that______.
A.we can get enough resources without rainforests
B.there is great medicine potential in rainforests
C.we will grow fewer kinds of crops in the gained land
D.the level of annual rainfall affects wind patterns
4. What might be the best title for the text?
A.How to Save Rainforests?B.How to Protect Nature?
C.Rainforests and the Environment.D.Rainforests and Medical Development.

【推荐1】About 97% of the world’s water is salty and is found in our oceans and seas. But, as we can’t drink sea water, how can it be important?

Every part of our seas and oceans contains an amazing number of animals and fish that live at different ocean depths. Most of the different species of animals and fish depend on simple plants for their food. These simple plants called algae (海藻) drift near the surface of the ocean and use sunlight to turn carbon dioxide and water into food and oxygen. In fact, algae produce over half of the oxygen people breathe. How important sea water is!

Each plant or animal in our seas and oceans is an important link in a food chain. The algae are eaten in large amounts by microscopic animals, which are in tur consumed by larger animals. These food chains are delicately (微妙地) balanced.

The bad news about the food chains in the oceans is that they are under threat because of man. People once thought that the oceans were so big that it didn’t matter if we dumped rubbish into them or caught huge quantities of fish and whales for food. But we now know this is not true and fish stocks in the oceans have started to drop.

Thankfully, the world is taking steps to protect the future of our oceans by introducing international agreements to protect marine habitats. Most counties have introduced fishing restrictions (限制) to protect fish stocks in the oceans and new techniques are being pioneered to cope with pollution. Finally, the importance of protecting oceans is being made known to more people. This is just the beginning of a long process to protect the oceans for our future. We depend on the oceans for fish which are an important part of the human diet. How important sea water is!

1. From the passage, we learn that _________.
A.most fish and sea animals live at the surface of the seas
B.it is very difficult to break the balance of a food chain
C.over-fishing has caused the decrease in fish stock
D.it won’t be long before the problems concerning oceans will be solved
2. What does the underlined phrase “cope with” mean in Chinese?
A.处理B.保护C.增加D.检验
3. Which of the following is NOT a way being used to protect oceans?
A.The use of international agreements.
B.Forbidding fishing to protect fish socks.
C.The use of new techniques.
D.Raising people’s awareness of the need to protect oceans.
4. What would be the best title of the passage?
A.The Importance of Sea Water
B.Life in the Oceans
C.How to Protect Food Chains
D.How to Deal with Seawater Pollution

【推荐2】A new report from University of East Anglia(UEA)shows that exposure to green space reduces the risk of type II diabetes, cardiovascular disease, stress, and high blood pressure. Populations with higher levels of green space exposure are also more likely to report good overall health.

Lead author Caoimhe Twohig-Bennett, from UEA’S Norwich Medical School, said, “Spending time in nature certainly makes us feel healthier, but until now the impact on our long-term wellbeing hasn’t been fully understood. We gathered evidence from over 140 studies involving more than 290 million people to see whether nature really does provide a health boost.”

The research team studied data from 20 countries including the UK, the US, Spain, France, Germany, Australia and Japan—where “forest bathing” is already a popular practice. “Green space” was defined as open, undeveloped land with natural vegetation including urban green space, which included parks and street greenery. The team analyzed how the health of people with little access to green space compared to that of people with the highest amounts of exposure.

“We found that spending time in or living close to natural green space is associated with diverse and significant health benefits. It reduces the risk of type TT diabetes, cardiovascular disease, premature death, and preterm birth, and increases sleep duration. People living closer to nature also had reduced diastolic blood pressure, heart rate and stress. In fact, one of the really interesting things we found is that exposure to green space significantly reduces people’s levels of salivary cortisol—a physiological marker of stress. This is really important because in the UK, 11.7 million working days are lost annually due to stress, depression or anxiety.”

“Forest bathing is really popular as a therapy in Japan, with participants spending time in the forest either sitting or lying down, or just walking around. Our study shows that perhaps they have the right idea! Although we have looked at a large body of research on the relationship between green space and health, we don’t know exactly what it is that causes this relationship. People living near green space likely have more opportunities for physical activity and socializing. Meanwhile, exposure to a wide variety of bacteria present in natural areas may also have benefits for the immune system and reduce inflammation (炎症),” Twohig-Bennett stated.

Study co-author Prof Andy Jones, also from UEA, said, “We often reach for medical treatment when we’re unwell but exposure to health-promoting environments is increasingly recognized as both preventing and helping treat disease. Our study shows that the size of these benefits can be enough to have a meaningful clinical(临床的) impact.”

The research team hopes that their findings will prompt doctors and other healthcare professionals to advise patients to spend more time in green space and natural areas.

1. What do we know about exposure to green space from the first two paragraphs?
A.290 million people will see its effectiveness.
B.People have been cured of several diseases by this way.
C.People seeing less green space can’t report good health.

A.green space often exists in places with small populations
B.space in the countryside is certainly green space
C.an urban green belt is a kind of green space
D.green space in the cities usually has little effects on people’s health
3. What does the author do in Paragraph 4?
A.Analyze the research process.
B.Introduce the research findings.
C.Show his concern about people’s health.
D.Explain why green space is good for patients.
4. Prof Andy Jones holds the view that            .
A.their study will improve the professionalism of doctors
B.exposure to green space can help treat disease effectively
C.one should see a doctor immediately when unwell
D.people are increasingly going to health-promoting spaces

【推荐3】Famous people have a lot of influence on cultural trends, like it or not. When Amal Clooney wears a Stella McCarney dress, sales go way up. However, one trend that seems harmlessbut is actually damaging—is the pressure on stars to have their photos taken with rare animals.

Famous people who are asked to have photos taken with wild animals for a magazine spread or who do so while on vacation always have good intentions and even love animals. This makes them easy targets for the often greedy amusement parks and fake animal centers. These businesspeople love the thought of sharing pictures of a star hugging a baby tiger or a whale. Kind people are naturally drawn to places that claim to offer rare animals safety and are eager to see elephants paint, to hug baby bear or to swim with dolphins. However, it has shown that many of these businessmen are breeders, dealers or exhibitors that are using Hollywood’s goodwill for their own ends.

At the recently closed Tiger Temple in Thailand, 40 dead tiger cubs(幼崽) were found in a freezer, secretly killed to make tiger wine and other folk medicine for sale on the black market. But it isn’t just the “tiger temples” that are being closed down. The number of tourist traps using word like “rescue” in their names has increased greatly in recent years.

Many businessmen continually breed the animals just so they’ll have a constant supply of young animals in order to charge money for photos to people. Of course the babies are cute but they grow fast, and within a few weeks they are too big to handle. They’ll spend the rest of their lives, sometimes decades, in small and empty cages — or even be killed.

In some Asian countries, elephants are kept in camps. A few camps are working to help elephants in trouble, but the vast majority are not, and training methods are cruel. As soon as the cameras are gone after someone like Prince William takes 0a photo with an elephant, the chains go back on.

Fans, tell the stars: Stay away from rare animal photos, and the animals will be grateful. Of course, you don’t have to be famous to make a difference. Whether right here at home or at a place abroad, every one of us must fight the temptation to take a photo with an elephant or hug a baby tiger.

1. The author intends to make an appeal that ________.
A.all people including stars should refuse to take photos with rare animals
B.measures should be taken to protect the rare animals
C.bans should be issued to limit celebrities’ behavior
D.warns of wild animals should be given to the public
2. It can be inferred that ________.
A.tiger wine and folk medicine made from tiger babies are sold in the supermarket
B.most of the elephants in Asia are treated well in camps
C.people are attracted to amusement parks and fake animal centers where celebrities share photos
D.when the baby animals that take photos with tourists grow up, they will be set free
3. Businessmen use the following tricks to make profits EXCEPT ________.
A.in the name of rescuing rare animals
B.take advantage of famous people to take photos with animals
C.claim to offer rare animals safety
D.protection of rare animals
4. Which of the following do you think is the best title?
A.Tell stars to stop!
B.Be careful when sharing photos on media!
C.No sale, no killing!
D.Rescue the endangered animals!
