Geology and Health
1. The importance of particular metals in the human diet has been realized within the past few decades,and the idea that geology might be related to health has been recognized for a number of elements such as iodine,zinc and selenium. For example,soils with low iodine contents produce crops,and animals deficient in iodine.A lack of iodine in the human diet leads to some serious diseases.
2.The ultimate source of metals within the human body is rocks,which weather into soil.gaining or losing some of their chemical constituents. The crops we eat selectively remove from the soil the elements that they require for growth .The water we drink contains trace elements leached from rock and soil. Thus the geology and geochemistry of the environments have effects on the chemis-try and health of plants,animals and people.
3. So far there is no data to suggest that people living on metal-rich soils experience a potential health hazard. The levels of metals within naturally contaminated soils are generally not high enough to cause serious health problems.Living on metal-rich soils does not represent a health risk unless large quantities of soil are digested or metal-rich dust is inhaled.However,small chil-dren are particularly exposed to metal-rich topsoil in playgrounds and gardens. They are also the most likely ones to eat potentially dangerous metal-rich soil.
4. Heavy metals are persistent:they do not break down to other chemicals in the environment. Industrially polluted sites usually undergo intensive clean-up and rehabilitation because heavy metals are a health concern once they enter the food chain. Some trace metals are alleged to cause cancer and are also known to cause poisoning.
5.In contrast,naturally contaminated soils have not been subject to risk assessment studies and rehabilitation measures,despite the fact that they frequently possess metal concentrations well above those of such polluted by humans and above environmental quality criteria.
6.There is a vital need to understand the potential risks and long-term health effects of living on naturally contaminated soils.Future environmental investigations of naturally polluted soils should concentrate on the potential pathways of metals into the food chain and human body.Geologists should be part of such studies as they can provide the essential background information on rock and soil chemistry as well as the chemical forms of heavy metal pollution.Paragraph 1______
A:.No evidence to indicate bad effects of naturally contaminated soil
B:.Potential hazards of human contaminated soils
C: Research on channels of heavy metals getting into human food chain
D: Geology and health problems
E:.Rocks-the ultimate source of soil pollution
F: Long-term health effects on children答案：D解析：第一段点出主题，即某些金属进入人类食谱可能与地质有关。
第三段涉及的是自然污染的土壤一般情况下对人体不会造成危害。此段首句就提示了这一点：“ So far there is no data to suggest that people living on metal-rich soils experience a potential health hazard.”
第四段说，受到工业污染的土壤含有重金属，而重金属很稳定，不容易分解。因此，某些微量重金属被认为有可能与癌症有关，并引起中毒。
答案的依据是本段的第二句：“ Future environmental investigations of naturally polluted soils should…into the food chain and human body.”
第一段最后一句“A lack of iodine in the human diet leads to some serious disease.”是选择E的依据。

问答题Directions： Cars play an important role in modern society. But they are also responsible for a good part of air pollution in big cities. Write an essay on car and air pollution and base your composition on the outline below: （1）the serious problem of air pollution caused by cars; （2）your suggestions on how to deal with the problem. You should write about 150 words neatly on the ANSWER SHEET.正确答案：
Cars and Air Pollution Cars are indispensable in modern society. However, too many cars have created a lot of serious problems. Besides traffic congestion, accidents and fast fuel consumption, cars are responsible for a good part of air pollution in big cities. All the time, they are pumping a huge amount of waste gases into the atmosphere. These gases are very harmful, causing disease and even death. Last winter, car fumes formed heavy smog over Beijing, making the sky gloomy for weeks and doing harm to people’s health.
One possible solution to the problem is to develop clean cars and clean fuels. In Beijing some of the buses have begun to run on natural gas, which does not give off as much carbon dioxide as the petrol. In Tsinghua University, campus buses are driven by electricity. But it may take decades for the new models of clean cars and clean fuels to completely replace the traditional ones.
Another solution is to improve modern public transportation systems and restrict the use of private cars. If the public transportation system is efficient and convenient enough, most people will choose means of public transportation over private cars. And the total number of cars in big cities will be reduced greatly.
On the whole, the problem of air pollution caused by cars can only be solved by the co-efforts from the government and the public and with the help of science and technology.解析：
本篇作文同样属于问题解决型，作文第一段首先肯定了汽车在现代生活中占据着不可替代的位置，接着提出汽车过多排放出大量尾气，对环境造成的严重影响；第二、三段提出了可能的解决办法，即开发清洁能源和提高交通系统，减少私家车的数量；最后一段强调汽车所造成的空气污染问题需要政府和公众联合的努力。
