Snow-melting Agent

A heavy snow can kill pests and this means a good harvest next year.This will bring as well as trouble to urbanites.

On Nov.16,2003,a cold air current brought a heavy snow to Beijing.To prevent traffic jams,related government departments mobilized people to clear off snow on streets.

One of the most effective ways to clear off snow on roads is to scatter snow-melting agent on the roads.The major component of the snow-melting agent is salt.The snow-melting agent can make snow stop from freezing,make it easier to clear off the road,and allow traffic to flow smoothly.But it also brings about some hidden dangers.In the spring of 2003,over 300 000 trees in Beijing urban districts died.After analyzing soil around these trees,experts discovered that the salt content of these soils was 392 times higher than normal.Where did the excessive salt come from?After investigating,forestry experts found that when clearing snow in the winter,people usually heap snow containing snow-melting agent at trees’ roots,and that when the snow melts,this agent penetrates the soil and increases its salt content.The snow-melting agent indirectly killed the trees.

Statistics show that during a heavy snow in 2002,over 1000 tons of snow-melting agent was scatterred on streets in Beijing.Snow water containing a large amount of snow-melting agent got into the soil through sewers.

In addition,salt in the snow-melting agent can expedite the corrosion of steel bars in concrete buildings and cause the concrete to crack and peel,shortening the life of roads.

Scientists and government officials are required to solve traffic problems caused by heavy snows as soon as possible and at the same time try to reduce the negative effects of the snow-melting agent.This is a difficult problem placed before them.Related authorities have framed some local criteria to regulate the production and use of snow-melting agents.

Now,more harmless snow-melting agents are being developed.Now that even snow-melting agents that meet today’s criteria must still be used carefully,we have to rely more on our manpower and machines to clear off snow.

This year,in addition to using snow-melting agents,Beijing will use a large number of snow vehicles to clear snow on roads.In more places,citizens are mobilized to clear snow with their hands.This may be a test of a city’s civilization level.

Salt is a snow-melting agent while _________ is a cleaning agent.

A.water B.soap C.a washing-machine D.a housewife

The third paragraph of the text is mainly about _______.

A.the side effect of snow-melting agent

B.a case of damage to trees caused by snow-melting agent

C.the results of using snow-melting agent

D.the uses of snow-melting agent

According to the text,the most practical way to clear off snow is to _________.

A.use snow-melting agent as much as possible

B.only use more harmless snow-melting agent

C.encourage people to clear snow with their hands

D.use more snow vehicles

This text most probably appears in_________.

A.a newspaper B.a magazine on latest findings

C.a book on salt D.a magazine on environmental protection

Even a small reduction in salt in the diet can be a big help to the heart. A new study used a computer model to predict how just three grams less a day would affect heart disease in the United States.
The result: thirteen percent fewer heart attacks. Eight percent fewer strokes. Four percent fewer deaths. Eleven percent fewer new cases of heart disease. And two hundred forty billion dollars in health care savings.
Researchers found it could prevent one hundred thousand heart attacks and ninety-two thousand deaths every year.
The study is in the New England Journal of Medicine. Kirsten, at the University of California, was the lead author. She says people would not even notice a difference in taste with three grams, or one-half teaspoon, less salt per day. The team also included researchers at Stanford and Columbia University.
Each gram of salt contains four hundred milligrams of sodium, which is how foods may list their salt content.
The government says the average American man eats ten grams of salt a day. The American Heart Association advises no more than three grams for healthy people. It says salt in the American diet has increased fifty percent since the nineteen seventies, while blood pressures have also risen. Less salt can mean a lower blood pressure.
New York City Mayor Michael Bloomberg is leading an effort called the National Salt Reduction Initiative. The idea is to put pressure on food companies and restaurants.
Mayor Bloomberg has already succeeded in other areas, like requiring fast food places in the city to list calorie information. Now a study by the Seattle Children's Research Institute shows how that idea can influence what parents order for their children.
Ninety-nine parents of three to six year olds took part. Half had McDonald's menus clearly showing how many calories were in each food. The other half got menus without the calorie information.
【小题1】 How many heart attacks will occur in the US every year？

A．nearly 800,000.	B．24,000.

【小题3】The National Salt Reduction Initiative aims to .

A．advise Americans to eat less salt

B．put pressure on food companies and restaurants

C．require fast food places to list calorie information

　 Far from the land of Antarctica(南极洲), a huge shelf of ice meets the ocean. At the underside of the shelf there lives a small fish, the Antarctic cod.

　 For forty years scientists have been curious about that fish. How does it live where most fish would freeze to death? It must have some secret. The Antarctic is not a comfortable place to work and research has been slow. Now it seems we have an answer.

　 Research was begun by cutting holes in the ice and catching the fish. Scientists studied the fish’s blood and measured its freezing point.

　 The fish were taken from seawater that had a temperature of -1.88℃ and many tiny pieces of ice floating in it. The blood of the fish did not begin to freeze until its temperature was lowered to -2.05℃. That small difference is enough for the fish to live at the freezing temperature of the ice-salt mixture.

　 The scientists’ next research job was clear: Find out what in the fish’s blood kept it from freezing. Their search led to some really strange thing made up of a protein(蛋白质) never before seen in the blood of a fish. When it was removed, the blood froze at seawater temperature. When it was put back, the blood again had its antifreeze quality and a lowered freezing point.

　 Study showed that it is an unusual kind of protein. It has many small sugar molecules(分子) held in special positions within each big protein molecule. Because of its sugar content, it is called a glycoprotein. So it has come to be called the antifreeze fish glycoprotein, or AFGP.

1. What is the text mainly about?

　 A. The terrible conditions in the Antarctic.

　 B. A special fish living in freezing waters.

　 C. The ice shelf around Antarctica.

　 D. Protection of the Antarctic cod.

2. Why can the Antarctic cod live at the freezing temperature?

　 A. The seawater has a temperature of -1.88℃.

　 B. It loves to live in the ice-salt mixture.

　 C. A special protein keeps it from freezing.

　 D. Its blood has a temperature lower than -2.05℃.

3. What does the underlined word “it” in Paragraph 5 refer to?

　 A. A type of ice-salt mixture.　　 B. A newly found protein.

　 C. Fish blood.　　　　　　　 D. Sugar molecule.

4. What does “glycol-” in the underlined word “glycoprotein” in the last paragraph mean?

　 A. sugar　　　　 B. ice　　　 C. blood　　　　 D. molecule
