完成下列各选项 A A greenhouse is a building made of glass whi

ch is used for keeping plants warm when the outside temperature is how．In a similar way there are several gases in the atmosphere which trap(捕捉)the heat produced by the sun and prevent it from escaping．These gases are known as“greenhouse gases“，and the way in which they trap heat in the atmosphere is called the “greenhouse effect”．This is not simply air pollution．Most of the main greenhouse gases exist naturally in small amounts in our atmosphere．And without them earth would be 30 degrees colder and human life would not exist．In other words，the greenhouse effect is a natural course which is to some degree helpful to us． The problem is that in the last century and a half．we have been putting too many 0f these gases into the earth’s atmosphere by burning large quantities of coal and oil and by cutting down forests．The rapid increase in greenhouse gases is making the world warmer．The world's temperature has already gone up by half a degree this century，and the sea level has risen by lo centi-metres．If the amount of carbon dioxide(二氧化碳)in the atmosphere doubles，there will probably be a rise in the earth’s temperature of between l and 4 degrees．This may seem a small in—crease，but it would be enough to cause major changes in geography and agriculture．Large areas of the world would be flooded．and some areas would become dry and unable to produce crops．It is important，too，to consider that there may be a delay of about 30 years in the greenhouse effect．This means that we’re probably experiencing only now the effect of the gases put into the atmosphere before the l960s．Since then，our use of these gases has greatly increased． “Greenhouse effect”means________．

A.a natural course which is to some degree helpful to us

B.the way．in which gases are used for keeping plants warm

C.the way“greenhouse gases”trap heat on the earth

D.the whole course in which greenhouse gases prevent heat

Mountain climbers around the world dream about going up Mountain Everest （珠穆朗玛峰) . It

Mountain climbers around the world dream about going up Mountain Everest (珠穆朗玛峰) . It is the highest mountain in the world. But many people who have climbed the mountain have left waste material that is harming the environment.

A team of Americans is planning the largest clean-up effort ever on Mountain Everest. They will make the risky trip up the mountain next month.

The team of eight Americans will be guided by more than twenty Sherpas of Nepal (尼泊尔夏尔巴人).Their goal is to remove all the trash they see. They will spend two months cleaning up the mountain by gathering oxygen bottles, fuel containers, batteries, drink cans, human waste and other kinds of trash. They are expected to remove at least three tons of trash in large bags.

Team leader Robert Hoffman is making his fourth trip up the mountain. He says he hopes to bring Everest to the condition it was in before the first successful climb fifty years ago. He says he hopes the effort will influence other people to clean up the environment closer home.

Human waste on Everest is a major concern. So the clean-up team will take along newly development equipment to collect and treat human waste. Over the years, the waste articles have polluted the mountain. In the warm season when the ice melts, the polluted water flows to Nepali villages below. The problem has gotten worse in recent years because climbing Everest has become more popular.

When those Americans are planning the trip up Mountain Everest, they are concerned about______.

A．the success in climbing up the mountain

B．the environment pollution of the mountain

C．the equipment for their trip to the mountain

D．the risks facing the mountain climbers
