Antarctica(南极洲) is known for being a vast land of ice and snow, a place too cold for most life. Despite (尽管) this, the continent is slowly starting to turn warm. According to the Guardian, the Antarctic has registered (登记) a new high temperature for the first time on record, prompting fears of climate instability(不稳定性) in the world’s iciest place.

On Feb 9, Brazilian researchers at Seymour Island reported a temperature of 20.75℃ on the icy continent of Antarctica. It was almost a full degree higher than the previous record of 19.8℃, taken on Signy Island in January 1982.

This record-breaking reading was taken at a monitoring (监测) station in the northern part of Antarctica. According to Brazilian soil scientist Carlos Schaefer, the temperature was documented during a 20-year-long research project. The focus of this project is to study the effect that climate change has on the permafrost (永久冻土) within the region. Permafrost is soil that stays frozen for at least two years. Although this is a first record high for Antarctica, Schaefer stressed that “We can’t use this to anticipate (预测) climatic changes in the future. It’s simply a signal that something different is happening in that area.”

But in fact, the last high temperature reading was in the 19℃ range. These higher temperatures can cause ice and glaciers (冰川) in Antarctic regions to melt. The Antarctic peninsula (半岛) —the long finger of land(狭长地带) that stretches towards Argentina（阿根廷）—is most dramatically affected. Scientists saw glaciers that have retreated by more than 100 meters in Discovery Bay where the snow melted in little more than a week, leaving dark exposed rock. This melted ice leads to a rise in sea levels that can threaten the safety of coastal areas. It’s believed to be behind an alarming decline of more than 50 percent in chinstrap penguin (帽带企鹅) colonies, which are dependent on sea ice.

Like American writer Ernest Hemingway once said, “The Earth is a fine place and worth fighting for.” We should do everything we can to help save our planet. Otherwise, it may become too hot for us to fix.

A.Signy Island is the warmest region in the Antarctic.

B.Antarctica hit a record high temperature of 20.75℃.

C.The average temperature of Antarctica ranges from 19.8 C to 20.75℃.

2.What’s the main purpose of the 20-year-long research project?

A.To predict possible climatic change in the future.

B.To monitor Antarctica’s contributions to world climate change.

C.To explain why the permafrost may cause glaciers to melt.

D.To examine how the permafrost is influenced by climate change.

3.What does the underlined word “retreated” probably mean?

A.Moved backward. B.Increased in size.

C.Covered a certain area D.Stretched in an opposite direction.

4.According to the text, the melted glacier may lead to________.

The weather of Antarctica(南极洲)is cold, cloudy with heavy snow. Most parts of it are covered with ice sea for 10 months. Though it is dry and seldom rains, scientists in Antarctica have gotten their first crop of vegetables that they grew without earth. As one part of a plan, it will help astronauts to study fresh food about other planets.If the plan is successful, people will have some space to plant vegetables and fruit.

Researchers at Germany's Neumayer Station III say they have planted 3.6 kilograms (about 8pounds) of salad green vegetables, including 18 cucumbers and 70 carrots in a high technology greenhouse(温室)，while the temperatures outside dropped below -200C. In this way, they can eat fresh vegetables in time.

The German Aerospace(航天航空) Center DLR, Daniel Dchubert, which was the leader of the plan, said on Thursday,“Scientists hope to get 4 to 5 kilograms of fruit and vegetables a week in May.Maybe the plan can turn into reality."

While NASA has successful grown green plants on the International Space Station, DLR's Daniel Dchubert says the Antarctic plan decides to produce a wider range of vegetables, such as tomatoes, onions and so on. People might grow them on the Mars or the Moon one day.

We know people depend on agriculture since the beginning of human history.

Without agriculture,people can't live for many years. At the same time, the development of agriculture needed some conditions,including environment, temperature, weather and so on. The technology develops quickly. People will plant the vegetables on the Mars sooner or later.

1.What's the weather like in Antarctica according the passage?

A.Sunny and cold. B.Cool and snowy. C.Dry and rainy. D.Seriously bad.

2.From Daniel Dchubert' s words , we can learn that_________.

A.Antarctic plan will produce more kinds of vegetables

B.more vegetables might be grown on the Sun or the Moon

C.Antarctic plan may be useless to other planets, like the Mars

D.Green plants will be grown on the International Space Station

3.Which of the following is TRUE according to the passage?

A.3.6 kilograms is 9 pounds. B.No people are living in Antarctica.

C.People will plant vegetables on the Mars. D.Scientists in Antarctica can't grow vegetables.

4.What' s the meaning of the underlined word“agriculture” in Chinese?

A.航天. B.工业. C.农业 D.服务业.

5.What' s the best title for the passage?

A.Green vegetables in Antarctica. B.Special weather in Antarctica.

The population of Earth is still going up. There will be less and less good land for growing crops in the future. People worry that there will not be enough food for everyone in the middle of this century.

Recently scientists have discovered one strange plant

named fedtschenkoi（玉吊钟）may help. It can absorb（吸收）carbon dioxide(CO₂)

at night. It only needs 10 times less water than food plants like beans. This means it

can grow in the desert(沙漠).

In which ways could this plant help us?

Since deserts are increasing in size because of the changes in Earth’s climate, growing plants there will be more and more important. Although it is dangerous to

eat this plant, scientists can still study something about it: how it absorbs CO₂ at

night while many other plants only do this during the day, and why it is suited to the

desert.

There is another direction to take the research in. Producing a desert plant to eat

will be difficult, but there is still possibility to use the genes(基因)from this plant and put them into food plants.

The other way is to grow this type of plant for fuel(燃料). At the moment we

grow plants for fuel in good land. If we do it in deserts instead, more good land can be used to grow plants for food.

Desert plants have special qualities, which could be an answer to our future food

or energy needs. Scientists are working hard on it.

India is known as the land of festivals. Every festival has its own celebration activities and my favourite festival is Diwali (光明节). Every autumn I go to stay with my cousins, so we can celebrate Diwali together.

Diwali is the biggest festival in India and people celebrate it all over the world. It is a magical time for children because of the lights. We light candles and lamps(灯), called "diyas", in our homes. All the streets, houses and shops are decorated with lights. Diwali comes from the Sanskrit (梵语) word "Deep-awali" which means "rows of lights".

On the morning of Diwali, I go to the temple with my family. On this occasion, we get dressed in our best clothes. My grandmother always buys me a new sari(沙丽) to wear for Diwali every year. We spend a long time getting ready, putting on bright clothes and jewellery. Lots of our friends come to the temple and we sing, dance and enjoy ourselves. My cousin play's an Indian instrument called harmonium (小琴)　 at the temple. There are always delicious sweet foods to eat. Back at my uncle's house, we exchange presents and eat lots of good Indian food. Many relatives come over to celebrate with us and it is a very special time for families.

　　　 Every- year, Diwali falls in October or November. Not only in India, but also in Asian countries, Diwali is celebrated with great joy and happiness.

Antarctica(南极洲）is the coldest place on the earth, but every year thousands of tourists go there. Why do they go? There are no famous buildings, no hotels and no restaurants. There are some beaches, but nobody wants to go swimming. Why do people want to take a vacation in Antarctica?

Most people go to see the birds, the animals and the amazing scenery. There are seals(海豹）lying on the ice. There are whales swimming in the ocean. You can also watch penguins jumping into water from icebergs(冰山). It’s one of the last untouched places on the planet.

It’s possible to visit Antarctica by plane, but most people go there by ship. That’s because the ships are comfortable places to stay, and the journey (by sea) is part of the vacation. All tourists visit Antarctica in the summer. In the winter it’s too cold for visitors, but in the summer—from November to March—it’s warmer than many people think. In some parts of Antarctica in January, it’s about 0℃. So it can be warmer there than it is in Beijing in January. When you visit there, you don’t need to bring a lot of special clothes. Instead, you need to bring sunglasses. The sunshine on the snow and ice is very bright.

Tourists are not the only people who go to Antarctica. In the summer months there are about 4,000 scientists and other people living and working there, and a few of them stay for the long, drink winters. Tourists can visit some of these people and learn about their work in this amazing place.

People in Los Angeles are known for their love of cars. The city is very large, and its public transportation is slow. So people drive everywhere. But now, a group of bicyclists are trying to get people out of their cars and on bikes.

Devon Fitzgerald says he has to be careful when he rides his bike in the streets. “A lot of people are in a rush, and it's very difficult to keep careful, for they would rather care for their speed than your safety.” Although riding a bike to work can be dangerous, he prefers it to a car. “It's much simpler than driving a car. For example, I don't have to worry about parking.”

Roger Rosas drives to work. "You always have to make sure you look to the other side because someone would rush across by bike. Or you can easily get into an accident. "
