People living more than three thousand meters above sea level find it difficult to raise vegetables all year long. People living in the highlands of Peru and Bolivia, for example, cannot grow vegetables outdoors during the months of May through September. It is very cold in the highlands at that time of year. If traditional farming methods are used, vegetables will not survive.

However, there is another way to grow vegetables throughout the year in cold areas. It is a method of gardening developed by a private agency called World Neighbors. The method uses “hot houses” built below ground. A hot house is a building covered with plastic or glass in which vegetables or flowers are grown. The traditional hot house is built above ground.

The air temperature is cold in the highlands of Peru and Bolivia during the winter. But, the winter sun is hot. So, World Neighbors advises farmers there to build hot houses below ground. The design is simple. The material does not cost much. Here is how World Neighbors says to build it: Dig a hole two and one-half meters wide and six meters long. Make it about two meters deep. Build wall with a door in one end of the hole. Dig steps from the ground down to the door.

Now, build a wall along the top edge of the hole. Make it about one-half meters tall. Earth bricks work fine. Build two shorter walls on the ends. These will be uneven; one side will be as high as the existing wall. The other side will be at ground level. Leave a small opening in each of these sloping walls. This prevents the hot house from becoming too hot. Now, make the roof. Build a wood frame. Cover it with clear plastic. Connect it to the brick walls.

The underground hot house we have described is large enough for two raised vegetable beds. Each is one meter wide and six meters long. Each is seeded and watered just as if it were in a garden above ground.

The dirt walls protect the growing plants from the cold. The clear plastic roof permits the sun’s heat to enter. At night, the roof should be covered with straw. This helps prevent cold air from entering. An under ground hot house this size will provide enough vegetables for one family. Groups needing more vegetables can make it bigger.

66. If you lived in Peru, you _______.

A. should raise the special kinds of vegetables that can endure cold

B. could not plant at all

C. had to work out some new unusual plans

D. would not have many vegetables to eat

67. To our surprise, the “hot houses” invented by World Neighbors are _______.

A. covered with a transparent plastic ceiling

B. built under ground

C. quite small

D. hotter than traditional ones

68. The hot house can be kept warm by using _______.

A. a big oven  B. an electricity heater

C. the heat of the earth’s interior   D. the sun shine

69. The measure to prevent the hot house from becoming too hot is to _______.

A. make the roof sloped B. dig holes on the walls

C. make the wall not vertical D. make the walls shorter than the ground level

70. According to the passage, the method suggested by World Neighbors is _______.

A. new and difficult      B. uneasy to explain

C. at trial step D. simple and practical

Something’s happening at the lowest point on our planet,some 1,388 feet below sea level.The Dead Sea,a salt lake close to Israel,Jordan and the West Bank,is shrinking at an alarming rate—about 3.3 feet per year,according to the environmentalist group EcoPeace Middle East.

“It’s not just like one country is punishing the Dead Sea;it’s more like the whole region,”said photographer Moritz Küstner,who visited the area in February to work on his series “The Dying Dead Sea”.

The Dead Sea needs water from the other natural sources surrounding it,such as the Jordan River basin.But around the 1960s, the courses of some water sources it relied upon were diverted. Israel, for instance, built a pipeline during that time so it could supply water throughout the country.

Mineral extraction(提取)industries are another main reason why the water levels are declining,experts say.The Dead Sea’s minerals have been popular for their medical power and can often be found in cosmetics(化妆品)and other consumer products.

And then,of course,there’s the Middle East’s hot,dry climate,which makes it difficult for the lake to refill itself.Last year,Israel and Jordan signed a $ 900 million deal in an effort to stabilize the Dead Sea’s water levels.It involves building a canal from the Red Sea to the Dead Sea which would be able to not only supply water to Israel and Jordan but also to pump much needed water—some 300 million cubic meters annually—into the Dead Sea.

“This is the most important and significant agreement since the peace treaty with Jordan (in 1994),”said Silvan Shalom,Israel’s energy and water resources minister at the time.Whether the canal—estimated to take three years to complete—will work out positively and as planned remains to be seen.

For now, Küstner shows us that the Dead Sea remains very much a place of interest, with people from all over the world going there to swim in its salty waters.

1.How many reasons for the Dead Sea’s shrinking does the author mention in the passage?

A. One. B. Two.

C. Three. D. Four.

2.What does the underlined word “diverted” in paragraph 3 mean?

A. Switch. B. Improve.

C. Accomplish. D. Repair.

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

A. The Dead Sea is drying out causing water shortage to humans.

B. Küstner visited the Dead Sea to shoot TV series about people’s life.

C. The Dead Sea’s minerals have been used in some products.

D. The Dead Sea’s water levels have been stabilized by building a canal.

4.What is the passage mainly about?

A. How the Dead Sea’s water levels’ decline influences human beings.

B. How important the Dead Sea is in Israel,Jordan and the West Bank.

C. What we should do to save the Dead Sea from being destroyed.

D. Why the Dead Sea is dying and the measure taken to save it.

Imagine yourself in a small airplane 3,300 meters above the ground. The engines roar in your ears as you move towards the open door. Then you' re outside, falling with the wind whipping past your ears. As the ground rushes up at you, you open your parachute. 1.. All in all, you were in free fall for only 30 seconds---the longest 30 seconds of your life.

2.. However, a growing number of adventurers are taking the risk. Obviously skydiving isn't something you can just try, like fishing or bowling. So, if you want to attempt the sport, you'll need to go to ground school.

3.. The course is taught by licensed skydiving instructors who have been jumping for years.

They'll teach you how to keep your body position stable. You'll also learn to be constantly aware of your altitude and, most importantly, when to open your parachute.

Once you' re through with ground school, it's time to get up in the air. 4.. Two instructors always jump with the person, ready to pull the student's parachute open if he or she freezes up.

5.. It certainly seems dangerous when you' re watching someone fall at 200 km/ hr. But, if you believe the statistics, skydiving is actually safer than driving, with one fatality (死亡) occurring in approximately 60, 000 jumps. Moreover, most enthusiasts agree all fear stops the second your feet leave the plane, and when you land, the only thought in your mind is, "Wow! I want to do that again!"

A. However, a new jumper never jumps alone.

B. It takes years to forget the taste of fear from skydiving.

C. No doubt, you're thinking skydiving is a dangerous sport.

D. It explodes over your head, pulling you back and upwards.

E. For most of us, skydiving is something we only see in the movies.

F. Ground school is where you learn to jump, without leaving the ground.

G. Skydiving is the sport of jumping out of an airplane and falling freely through the air.

Most of Bangladesh is at or below sea level. Rising seawaters linked to climate change has severely affected the country. High water from storms in coastal areas also adds salt to soil. The land is becoming salty. Crops are less productive and many areas of cropland in the country are becoming unfit for farming. These are big problems for the small country. More than 155 million people live in Bangladesh. Growing crops is the most common way Bangladeshis support themselves.

To find a way out, farmers in the country are learning to grow vegetables in so-called “vertical gardens”. The soil in these gardens is better because heavy rains have removed much of the salt.

A vertical garden is easy to make. Villagers fill containers with good soil and natural fertilizers. They put the containers on bricks so they are off the ground. They add pieces of the bricks to the soil to help water flow and drain(排水).

The farmers cut small holes into the sides of the containers. This permits vegetables with short roots a place to grow. Vegetables with long roots grow on top of the container. One bag of soil can produce up to eight kilograms of vegetables in one season.

The farmers also grow vegetables in containers made from large, thin pieces of plastic supported by bamboo. This “vertical tower” measures more than a meter wide. Each of these towers can produce more than 100 kilograms of vegetables. It costs about $12-S13 to build.

1.What is mentioned as a big problem for Bangladesh?

A. Severe climate conditions.

B. Too many people to support.

C. Lack of enough fresh water.

D. Reduced crop productivity.

2.Which mainly makes vegetable growing in vertical gardens successful?

A. Places in the soil for roots.

B. Heavy rains kept in the soil.

C. The good soil with little salt.

D. Brick pieces added to the soil.

3.What does the underlined word “they” in Paragraph 3 refer to?

A. Bricks.　　 B. Fertilizers.　　 C. Villagers.　　 D. Containers.

4.What can we infer about the vertical tower?

A. It is off the ground.

B. It drains very improperly.

C. It uses bamboo for containers.

D. It is unfit for growing vegetables.

The Maldives faces the threat of extinction from rising sea levels, but the government said on Thursday it was looking to the future with plans to build homes and a golf course that float.

An increase in sea levels of just 18 to 59 centimeters would make the Maldives -- a nation of tiny coral islands in the Indian Ocean -- virtually uninhabitable by 2100, the UN’s climate change panel has warned.

President Mohamed Nasheed has vowed a fight for survival, and last month he signed a deal with a Dutch company to study proposals for a floating structure that could support a convention centre, homes and an 18-hole golf course. “It is still early stages and we are awaiting a report on the possibility,” a government official said.

The company, Dutch Docklands, is currently building floating developments in the Netherlands and Dubai. There was no immediate comment from the firm but its website said it undertook projects that make “land from water by providing large-scale floating constructions to create similar conditions as on land”.

The Maldives began work on an artificial island known as the Hulhumale near the crowded capital island of Male in 1997 and more than 30,000 people have been settled there to ease congestion. The city, which has a population of 100,000, is already protected from rising sea levels by a 30-million-dollar sea wall, and the government is considering increasingly imaginative ways to combat climate change.

Nasheed, who staged the world’s first underwater cabinet meeting in October to highlight his people’s dilemma , has even spoken of buying land elsewhere in the world to enable Maldivians to relocate if their homes are flooded. He has also pledged the Hulhumale to turn his nation into a model for the rest of the world by becoming “carbon neutral” by 2020. His plan involves ending fossil fuel use and powering all vehicles and buildings from “green” sources.

1. What’s the main idea of the passage?

A. The Maldives plans to build floating homes for the rising sea level.

B. The Maldives’s president signed a deal with a Dutch company.

C. The Maldives staged the first underwater cabinet meeting.

D. The Maldives is considering ways to fight against the global warming.

2. Which statement is true about the Hulhumale?

A. The Hulhumale is a natural island near the capital of Male.

B. The Hulhumale is an artificial island to be built near the capital.

C. The Hulhumale was built in 1997 and has settled over 30,000 people.

D. The Hulhumale is protected by a 30-million-dollar sea wall.

3. According to the passage, the underlined word congestion means _______.

A. being endangered                     B. being crowded

C. being flooded                        D. being disappearing

4. Which of the following is NOT Nasheed’s idea?_______

A. To purchase land elsewhere in the world to help Maldivians to relocate if their homes are flooded.

B. To make his nation a model for the rest of the world by becoming “carbon neutral” by 2020

C. To stop using fossil fuel and power all vehicles and buildings from “green” sources.

D. To build more artificial islands for people to settle there.

5. We can infer from the passage that ________.

A. By 2100, all the the Maldives will live on artificial islands.

B. The plans to build homes and a golf course that float have been carried out

C. Maldive has been greatly affected by the global warming.

D. . Dutch Docklands is the president of Maldive.

No longer in the pink

Corals are comeback creatures. As the world froze and melted and sea levels rose and fell over 30,000 years, Australia’s Great Barrier Reef, which is roughly the size of Italy, died and revived five times. But now, thanks to human activity, corals face the most complex condition they have yet had to deal with.

According to the Intergovernmental Panel on Climate change, a rise in global temperatures of 1.5oC could cause coral reefs to decline 70-90%. The planet is about 1oC hotter than in the 19th century and its seas are becoming warmer, stormier and more acidic. This is already affecting relations between corals and the single-celled algae (海藻), which give them their color. When waters become unusually warm, algae float away, leaving reefs a ghostly white. This “bleaching” is happening five times as often as it did in the 1970s. Meanwhile the changing chemistry of the oceans makes it harder for corals to form their structures.

If corals go, divers and marine biologists are not the only people who will miss them. Reefs take up only a percent of the sea floor, but support a quarter of the planet’s fish diversity. The fish that reefs shelter are especially valuable to their poorest human neighbors, many of whom depend on them as a source of protein. Roughly an eighth of the world’s population lives within 100km of a reef. Corals also protect 150,000km of shoreline in more than 100 countries and territories from the oceans buffeting, as well as generating billions of dollars in tourism revenue.

Coral systems must adapt if they are to survive. They need protection from local sources of harm. Their eco-systems suffer from waste from farms, building sites and blast fishing. Governments need to impose tighter rules on these industrials, such as tougher local building codes, and to put more effort into enforcing rules against overfishing.

Setting up marine protected areas could also help reefs. Locals who fear for their livelihoods could be given work as rangers with the job of looking after the reserves. Visitors to marine parks can be required to pay a special tax, like what has been done in the Caribbean.

Many reefs that have been damaged could benefit from restoration. Coral’s biodiversity offers hope, because the same coral will grow differently under different conditions. Corals of the western Pacific, for example, can withstand higher temperatures than the same species in the eastern Pacific, which proves a way forward to encourage corals to grow in new spots.

1.According to the passage, what may happen to corals when waters become warm?

A.Turning white B.Getting pink

C.Being active D.Becoming colorful

2.According to the passage,corals can _______ the changing in the nature.

A.live with B.escape from

C.die in D.recovery from

3.According to Paragraph 4, the governments should__________.

A.carry out stricter rules on industries around the coast

B.call on volunteers to look after the marine reserves

C.reduce the number of visitors to the marine parks

D.ban people from fishing in the coral reef areas

4.What’s the main purpose of the passage?

A.To present the importance of coral reef to the world.

B.To introduce the severe effect on coral reef brought by climate change.

C.To propose governments to take action immediately to save coral reef.

D.To attract more attention to coral reef protection.
