閱讀材料，回答{TSE}題：
Geology and Health
1The importance of particular metals in the human diet has been realized within the past fewdecades, and the ideathat geology might be related to health has been recognized for anumber ofelements such as iodine, zincand selenium. For example, soils with low iodine contents producecrops, and animals deficient in iodine. alack of iodine in the human diet leads to some seriousdiseases.
2The ultimate source of metals within the human body is rocks,which weather into soil, gainingor losing some of their chemical constituents. The crops we eat selectively remove from the soil theelements that they require for growth. The water we drink contains trace elements leached fromrock and soil. Thus the geology and geochemistry of the environments have effects on the chemis-try and health of plants,animals and people.
3So far there is no datato suggest that people living on metal-rich soils experience apotentialhealth hazard. The levels of metals within naturally contaminated soils are generally not highenough to cause serious health problems. Living on metal-rich soils does not represent ahealthrisk 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 themost likely ones to eat potentially dangerous metal-rich soil.
4Heavy metals are persistent: they do not break down to other chemicals in the environment.Industrially polluted sites usually undergo intensive clean-up and rehabilitation B.ecause heavymetals are ahealth concern once they enter the food chain. Some trace metals are alleged to causecancer and are also known to cause poisoning.
5In contrast,naturally contaminated soils have not been subject to risk assessment studies andrehabilitation measures, despite the fact that they frequently possess metal concentrations wellabove those of such polluted by humans and above environmental quality criteria.
6There is avital need to understand the potential risks and long-term health effects of living onnaturally contaminated soils. Future environmental investigations of naturally polluted soils shouldconcentrate on the potential pathways of metals into the food chain and human body. Geologist.,should be part of such studies as they can provide the essential background information on rocband soil chemistry as well as the chemical forms of heavy metal pollution.
{TS}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
參考答案：D
參考解析：第一段點出主題，即某些金屬進入人類食譜可能與地質(zhì)有關(guān)。
Paragraph 3__________
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
參考答案：A
參考解析： 第三段涉及的是自然污染的土壤一般情況下對人體不會造成危害。此段首句就提示了這一點：“So far there is no datato suggest that people living on metal.rich soils experi.ence apotential heMth hazard.”
Paragraph 4__________
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
參考答案：B
參考解析： 第四段說，受到工業(yè)污染的土壤含有重金屬，而重金屬很穩(wěn)定，不容易分解。因此，某些微量重金屬被認為有可能與癌癥有關(guān)，并引起中毒。
Paragraph 6__________
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
參考答案：C
參考解析： 答案的依據(jù)是本段的第二句：“Future environmental investigations of naturally pollutedsoils should…into the food chain and human body.”
Some diseases is connected with deficiency of__________.
A.industrially polluted soils
B.rock and soil chemistry
C.naturally polluted soils
D.the pathways of metals into the food chain
E.the element of iodine
F.the persistence of heavy metals
參考答案：E
參考解析： 第一段最后一句“A.lack of iodine in the human diet leads to some serious disease.”是選擇E的依據(jù)。
It is extremely necessary to study the long-term effects caused by living on__________.
A.industrially polluted soils
B.rock and soil chemistry
C.naturally polluted soils
D.the pathways of metals into the food chain
E.the element of iodine
F.the persistence of heavy metals
ABCDEF
參考答案：C
參考解析： 本題答案的依據(jù)是最后一段的第一句，即“There is avital need to understand the po-tential risks and long—term health effects of living on naturally contaminated soils.”
Geologists are indispensable in the research project on geology and health due to their knowl-edge on__________.
A.industrially polluted soils
B.rock and soil chemistry
C.naturally polluted soils
D.the pathways of metals into the food chain
E.the element of iodine
F.the persistence of heavy metals
參考答案：B
參考解析： 全文都在論述重金屬的攝入可能會對人體健康產(chǎn)生有害影響。最后一段說到地質(zhì)學家在解決調(diào)查這個問題能起到的作用。這個句子是：“Geologists should be part ofsuch studies as they can provide the essential background information on rock and soil chem.istry as well as the chemical forms of heavy metal pollution.”
Industrially contaminated sites usually require athorough clean-up due to__________.
A.industrially polluted soils
B.rock and soil chemistry
C.naturally polluted soils
D.the pathways of metals into the food chain
E.the element of iodine
F.the persistence of heavy metals
參考答案：F
參考解析： 第四段涉及這一問題。受到工業(yè)污染的土壤含有重金屬，而重金屬很穩(wěn)定，不容易降解，所以，要對重金屬進行徹底的清除。
