71 But still there is a danger that grows every year. Airliners get larger. Some airplanes can hold over 300 passengers. And the air itself becomes more and more crowded. If one giant airliner crashed into another in mid-air, 600 lives could be lost.

72 . Air traffic controllers tell the pilot exactly when to turn, when to climb, and when to come down. The air traffic controllers around a busy airport like London-Heathrow may handle 25000 planes a day. Not all of them actually land at the airport. Any plane that flies near the airport comes under the orders of the controllers there. 73 .

Recently such a disaster almost happened. 74 . One, with 69 passengers, had come from Toronto, and the other, with 176 passengers, from Chicago. An air traffic controller noticed on his radar screen that the two planes were too close to each other. He ordered one to turn to the right and to climb. But he made a mistake. He ordered the wrong plane to do this. Fifteen seconds later it flew directly in front of the second plane. They avoided each other by the smallest part of a second. The distance between them was less than that of a large swimming pool. 75 .

A． Even a small mistake on their part could cause a disaster.

B． Two large jets were flying towards the airport.

C．Nowadays people like traveling more by air than by car.

D．Today, air travel is far safer than driving a car in a bus motor-way.

E． This is an example of the danger that grows every year.

F． In a word, air travel is more dangerous, we should choose others.

G． From the moment an airliner takes off to the moment it lands, every moment is watched on radar screen.

You can make the difference between this … and this. But how?

This summer, join the International Conservation (环境保护)Scouts on a fun—filled holiday with a difference. Year after year, young people from all around the world get together at one of our sixteen conservation camps. Their shared aim is to help protect the countryside and its wildlife.

Many animals and plants are in danger of disappearing forever. The dormouse, a kind of mouse, for example, needs woodland plants for food and trees to stay in. Its habitat is being destroyed by man and it needs our help to survive.

On a conservation camp holiday, you’ll learn all about nature and how to protect it. Our trained leaders will accompany you and tell you everything you need to know. Because of this you don’t need any experience, just energy and enthusiasm(热情). You will explore the countryside and work to ensure the survival of hundreds of animals and plants and still have plenty of time to enjoy the camp’s excellent sport games and organized nature paths through beautiful scenery.

The International Conservation Scouts is a world—wide organization, so there must be camp near you. You can spend a splendid holiday at any of the camps for as little as ￡60, including accommodation(住宿)and food.

TUVALU, a tiny country in the Pacific Ocean, has asked for help as it will be swallowed up by the sea.
Storms and huge waves are a constant threat and none of Tuvalu’s nine little islands is more than five meters above sea level. Salt water is already entering the country’s drinking water supply, as well as damaging plants that produce fruit and vegetable. Without urgent help, the country’s days are numbered.
But Tuvalu is not the first place to face sinking into the sea. Venice, a historic city in Italy best known for its canals, has sunk about 24cm over the past 100 years. Experts say that it will have sunk another 20-50cm by 2050. A century ago, St. Mark’s Square, the lowest point city, flooded about nine times a year. Nowadays, it happens more than 100 times. While Venice is slowly sinking into the mud on which it stands, global warming causes Tuvalu’s rising sea level.
The average global temperature has increased by almost 0.5 centigrade degrees over the past century; scientists expect it rise by extra 1-3 degrees over the next 100 years.
Warmer weather makes glaciers (冰川) melt, and adds more water to the ocean. The warmer temperatures also make water expand, so it takes up more space, causing the sea level to rise. The sea level has risen about 10-25 cm in the last 100 years.
The main cause of global warming is human pollution. Through burning coal, oil and gas, people have been increasing the greenhouse gases in the atmosphere, such as CO2. This adds to the power of the greenhouse effect, making the planet even warmer.
Many scientists believe that, if the warming is not stopped, there will be huge climate changes. The sea level could rise by one meter this century.
Should this come true, the sea will swallow up millions of homes and the world will be flooded with “climate refugees” looking for somewhere to live.

Tuvalu, a tiny country in the Pacific Ocean, has asked for help as it fears it will be flooded by the sea water.

Storms and huge waves are a constant threat and none of Tuvalu’s nine little islands is more than five meters above sea level. Salt water is already entering the country’s drinking water supply, as well as damaging plantations that produce fruit and vegetables. Without urgent help, the country’s days are numbered.

But Tuvalu is not the first place to face sinking into the sea. Venice, a historic city in Italy, best known for its canals, has sunk 24cm over the past 100 years. Experts say that it will have sunk another 20-50cm by 2050. A century ago, St. Mark’s Square, the lowest point in the city, flooded about nine times a year. Nowadays, it happens more than 100 times.

While Venice is slowly sinking into the mud on which it stands, Tuvalu’s rising sea level is caused by global warming.

The average global temperature has increased by almost 0.5 centigrade degree over the past century, scientists expect it to rise by an extra 1-3 degrees over the next 100 years.

Warmer weather makes glaciers(冰川) melt, adding more water to the ocean. The warmer temperatures also make water expand, so it takes more space, causing the sea level to rise. The sea level has risen about 10-25cm in the last 100 years.

The main cause of global warming is human pollution. Through burning coal and gas, people have been increasing the greenhouse gases in the atmosphere. This adds to the power of the greenhouse effect, making the planet even warmer.

Many scientists believe that, if the warming is not stopped, there would be huge climate changes. The sea level could rise by one meter this century.

Should this come true, millions of homes would be flooded by the sea water and the world would be flooded with climate refugees(难民) looking for somewhere to live.
