请阅读 Passage 1，完成第 21~25小题。Passage 1These days，many large city buildings are equipped with their own air-conditioning systems.These systems help keep the buildings cool，but they can also damage the environment.Since they use a lot of electricity，for instance，they contribute indirectly to global warming.In addition，the water that flows through the systems is often cooled using chemicals called chlorofluorocarbons，or CFCs，that are believed to damage the Earth's ozone layer.Recently，though，a system has been built in the city of Toronto，Canada，that cools buildings with little damage to the environment. In the traditional air-conditioning systems found in most large buildings，water is pumped through the building in a continuous cycle.The water is first cooled to a temperature of 4℃ in machines called chillers.It is then sent to individual units that cool the air in each room.As the water flows through the building，it gradually becomes warmer.Finally，it reaches the roof ，where it is left to cool down naturally in a water tower.After that it is returned to the chillers，where the cycle begins again.Toronto lies on the shore of Lake Ontario，one of North America's Great Lakes，and the new system makes use of cold water taken from about 80 meters below the surface of the lake.At this depth，the water in the lake remains at 4℃ all year round.This is exactly the temperature to which the water in air-conditioning systems is cooled.However，the water from the lake is not pumped directly into the air-conditioning systems.Instead，it is used to cool the water that is already inside the air-conditioning systems.After that，the lake water is added to the city's ordinary water supply.Enwave，the company that developed this deep-lake cooling system，says that it uses 75 percent less energy than traditional air conditioning.And since no CFCs are used，no damage can be caused to the ozone layer.Not every city is located next to a large lake，but experts believe that systems like the one being used in Toronto could be built elsewhere by using other natural sources of cold water.What is the function of the chillers in a traditional air-conditioning system?
A
They pump the air continuously to the units in each room.
B
They lower the temperature of the water in the system.
C
They help the water cool down naturally on the roof .
D
They gradually clean the water as it flows through the building.

Passage 1
African elephants have been slaughtered at alarming rate over the past decade, largely because they are the primary source of the world's ivory. Their population has been dwindled from 1.3 million in 1979 to just 625,000 today, and the rate of killing has been accelerating in recent years because many of the older, bigger tusked animals have already been destroyed. "The poachers now must kill times as many elephants to get the same quantity of ivory," explained Curtis Bohlen,Senior vice president of the World Wildlife Fund.
Though its record on the environment has been spotty so far, the government last week took the lead in a major conservation issue by imposing a ban on ivory imports into the US. The move came just four days after a consortium of conservation groups, including the World Wildlife Fund and Wildlife Conservation International, called for that kind of action, and it made the US the first nation to forbid imports of both raw and finished ivory. The ban, says Bohlen, sends a very clear message to the ivory poachers that the game is over.
In the past African nations have resisted an ivory ban, but increasingly they realized that the decimation of the elephant herds poses a serious threat to their tourist business. Last month Tanzania and several other African countries called for an amendment to the 102 nation Convention on International Trade in Endangered Species that would make the ivory trade illegal worldwide.
The amendment is expected to be approved at an October meeting in Geneva and to go into effect next January. But between now and then, conservationists contend, poachers may go on a rampage,killing elephants wholesale, so nations should unilaterally forbid imports right away. The US government brought that argument, and by week's end the twelve nations European Community had followed with its own ban.
According to the passage, "dwindle" (Para.1) means__________.
