Where Has the Salt Come from?Every now and then,we meet a fact about our earth that makes us feel strange and no answer for the fact has yet been found.Such a fact is the existence of salt in the oceans. How did it get there?We simply do not know how the salt got into the ocean!We do know,of course,that salt is water-soluble,and so passes into the oceans with rainwater.The salt of the earth's surface is constantly being dissolved（溶解）and is passing into the ocean.But we do not know whether this can explain the huge quantity of salt in oceans.If all the oceans were dried up,enough salt would be left to build a wall 180 miles high and a mile thick. Such a wall would reach once around the world at the Equator（赤道）!The common salt that we all use is produced from seawater or the water of salt lakes, from salt springs（源泉）and from deposits of rock salt. The concentration（浓度）of salt in seawater ranges from about three percent to three-and-one-half percent. The Dead Sea, which covers an area of about 340 square miles,contains about 11,600,000,000 tons of salt!On the average, a gallon（加仑）of seawater contains about a quarter of a pound of salt.The beds of rock salt that are found in various parts of the world were all originally formed by the evaporation（蒸发）of seawater millions of years ago. It is believed that the thick rock-salt deposits were formed after about nine-tenth of theY volume of seawater had been evaporated.Most commercial salt is obtained from rock salt.The usual method is to drill wells（井） down to the salt beds. Pure water is pumped down（抽进去）through a pipe. The water dissolves the salt and it is forced through another pipe up to the surface.A:Right B:Wrong C:Not mentioned

资料：Why is Salt Bad for You?
FRANK LE CLAIR, a 58-year-old provincial government employee living in Winnipeg, had no idea that his blood pressure was too high. While out of town last winter, he came down with a cold and a sore throat and decided to see a local doctor.
Apart from checking his cold symptoms, the doctor also gave him a general health-check. The doctor found that Frank’s blood pressure was higher than normal and advised him to see his regular physician as soon as he got home.
Le Clair’s physician referred him to the Winnipeg Health Sciences Centre, where dietitians told him that he might be able to control his blood pressure by changing his lifestyle rather than by taking drugs. People with high blood pressure have to control or eliminate four elements: smoking, drinking, food quantities and salt. Le Clair doesn’t smoke or drink, but there were some changes he could make in the other two categories.
The most conclusive evidence so far that a high-salt diet is bad for you is the “Intersalt” study, involving 10,000 people in 32 countries. It measured the relationship between urinary sodium excretion -- a direct measure of salt consumption -- and blood pressure. The study found that populations with the lowest sodium excretion also have the lowest blood pressures.
Recent studies have shown that “salt sensitivity” is a major factor in the relationship between a high-salt diet and hypertension. And hypertension is a risk factor for two of the biggest killers in this country: coronary heart disease and stroke. Frank Le Clair’s high blood pressure was discovered by chance. There are no warning symptoms -- high blood pressure is known as the silent killer.
A high-salt intake triggers a vicious cycle. Those who are used to a lot of salt in their food find they need increasing amounts to be able to continue to taste its flavour --- the more salt they eat, the more they want. It is also an aggravating factor in osteoporosis and is closely linked to stomach cancer. A high salt intake can be dangerous for people with conditions that are aggravated by fluid retention, such as hepatitis, liver or kidney problems.
Frank Le Clair was advised by ______ to adjust his lifestyle.A.his family doctor
B.a heart specialist
C.research scientists
D.a nutrition expert

B.purified water

单选题Passage2 Questions 6 to 10 are based on the following passage. Salt is as necessary to life as water. In many areas of Africa people once drank the urine（尿）of animals because they had no other source of salt. Without salt, human beings die. The human body demands that the amount of salt in the blood always stay the same. When the body does not get enough salt, it protects itself by letting less salt leave the body in. urine and sweat. But it cannot reduce this output to zero. Some salt is always escaping. On a completely saltless diet, like that of some people in Africa, the body steadily loses small amounts of salt through the kidneys（肾） and sweat glands(腺). It then tries to adjust to this loss by speeding up its secretion(分泌) of water. (78) In this way, the body attempts to keep the amount of salt in the blood at the necessary level. The result is a slow drying up of body and, finally, death. The person dies of thirst. In cases where there is little or no water to drink, the body tries to do the opposite thing.Again, it must keep the salt level in the blood constant. Because it has little water, it attempts to stop water from leaving the body and to increase its secretion of. salt. But, as with the escaping salt, it cannot be completely successful. Some water still leaves and the person eventually dies of thirst. In short, the body's normal needs for salt and for water are both parts of the same important need to keep the salt level in the blood constant.6 Some African people once drank animal urine______.A
