Promotion on the World Wide Web includes advertising, sponsorships and sales promotions like contests and coupons.

9、 In 1996, world wide web advertising revenues reached $ 300 million.Effective online marketers do not merely transfer hard-copy ads(平面广告) to cyberspace.

The importance of particular metals in the human diet has been realized within the past few decades, and the idea that g

20、eology might be related to health has been recognized for a number of elements such as iodine(碘), zinc(锌)and selenium(硒). 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 sour

21、ce 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 (过滤出) from rock and soil. Thus

22、the geology and geochemistry of the environment have effects on the chemistry 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 gener

23、ally 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 children are particularly exposed to metal-rich topsoil in playgrounds and gardens. They are

24、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 e

25、nter 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

26、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

27、 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.A. No Evidence to Indicate Bad Effects of Naturally C

The atmosphere again acts as our

32、protective blanket on earth light, gets through, and this is essential for plants to make the food that we eat. Heat, too, makes our environment endurable. Various kinds of rays come through the air from outer space, but enormous quantities of radiation from the sun are screened off. As soon as men

33、leave the atmosphere they are exposed to this radiation, but their spacesuits or the walls of their spacecrafts, if they are inside, do prevent a lot of radiation damage.Radiation is the greatest known danger to explorers in space. The unit of radiation is called “rem“ (“雷姆”). Scientists have reason

34、 to think that a man can put up with far more radiation than 0.1 rem without being damaged, the figure of 60 reins has been agreed on. The trouble is that it is extremely difficult to be sure about radiation damage-a person may feel perfectly well, but the cells of his or her sex organs may be damag

35、ed ,and this will not be discovered until the birth of deformed(畸形的)children or even grandchildren. Missions of the Apollo flights have had to cross belts of high radiation and, during the outward and return journeys, the Apollo crew accumulated a larger amount of reins. So far, no dangerous amounts

36、 of radiation have been reported, but the Apollo missions have been quite short. We simply do not know yet how men are going to get on when they spend weeks and months outside the protection of the atmosphere, working in a space laboratory. Drugs might help to decrease the damage clone by radiation

37、,but no really effective ones have been found so far.（分数：15.00）(1).According to the first paragraph, the atmosphere is essential to man in that_。（分数：3.00）A.it protects him against the harmful rays from spaceB.it provides sufficient light for plant growthC.it supplies the heat necessary for human sur

38、vivalD.it screens off the falling meteors(2).We know from the passage that_.（分数：3.00）A.exposure to even tiny amounts of radiation is fatalB.the effect of exposure to radiation is slow in comingC.radiation is avoidable in space explorationD.astronauts in spacesuits neednt worry about radiation damage

39、(3).The harm radiation has done to the Apollo crew members_.（分数：3.00）A.is insignificantB.seems overestimatedC.is enormousD.remains unknown(4).It can be inferred from the passage that_.（分数：3.00）A.the Apollo mission was very successfulB.protection from space radiation is no easy jobC.astronauts will h

40、ave deformed children or grandchildrenD.radiation is not a threat to well-protected space explorers(5).The best title for this passage would be_.（分数：3.00）A.The Atmosphere and Our EnvironmentB.Research on RadiationC.Effects of Space RadiationD.Importance of Protection Against RadiationB第二篇/BA Histori

41、cal Development of Oil RefiningAn important new industry, oil refining(炼油) ,grew after the Civil War. Crude oil, or petroleum-a dark, thick ooze from the earth-had been known for hundreds of years. But little use had ever been made of it. In the 1850s, Samuel M. Kier, a manufacturer in western Penns

42、ylvania, began collecting the oil from local seepages (油苗)and refining it into kerosene (煤油), Refining, like smelting(锻造), is a process of removing impurities from a raw material.Kerosene was used to light lamps. It was a cheap substitute for whale oil, which was becoming harder to get. Soon there w

43、as a large demand for kerosene. People began to search for new supplies of petroleum.The first oil well was drilled by E. L. Drake, a retired railroad conductor. In 1859 he began drilling in Titusville, Pennsylvania. The whole venture seemed so impractical and foolish that onlookers called it“ Drake

44、s Folly“. But when he had drilled down about 70 feet(21 meters) ,Drake struck oil; his well began to yield 20 barrels of crude oil a day.News of Drakes success brought oil prospectors (探寻者)to the scene. By the early 1860s these wildcatters (盲目采油者) were drilling for “black gold“ all over western Penn

45、sylvania. The boom rivaled the California gold rush of 1848 in its excitement and Wild West atmosphere. And it brought far more wealth to the prospectors than any gold rush.Crude oil could be refined into many products. For some years kerosene continued to be the principal one, it was sold in grocer

46、y stores and door to door. In the 1880s and 1890s refiners learned how to make other petroleum (石油) products such as waxes (石蜡) and lubricating oils (润滑油). Petroleum was not then used to make gasoline or heating oil.（分数：15.00）(1).What is the main idea of the passage?（分数：3.00）A.Oil refining: a histor

47、ical perspective.B.The California gold rush: get rich quickly.C.Private property: trespassers will be prosecuted.D.Kerosene lamps: a light in the tunnel.(2).It can be inferred from the passage that kerosene was preferable to whale oil because whale oil was too_.（分数：3.00）A.expensiveB.thickC.hotD.poll

48、uted(3).According to the passage, many people initially thought that E. L. Drake had made a mistake by_.（分数：3.00）A.going on a whaling expeditionB.moving to PennsylvaniaC.drilling oilD.retiring from his job(4).The author mentions all of the following as possible products of crude oil EXCEPT_.（分数：3.00

49、）A.waxB.gasolineC.keroseneD.plastic(5).Why does the author mention the California gold rush?（分数：3.00）A.To explain the need for an increased supply of gold.B.To indicate the extent of United States mineral wealth.C.To describe the mood when oil was first discovered.D.To argue that gold was more valuable than oil.B
