24、the middle of winter,n加油 when snow is falling in mn加油any parts of the United Stan加油tes, scientists have soundedn加油 a warning to people who n加油plan to spend many hoursn加油 in the sun this summer. n加油The warning is: The sunn加油s summertime rays are more dan加油ngerous than once thought. n加油 A team of scie

25、ntists n加油from 80 nations recentlyn加油 reported to the Uniten加油d Nations that a layer of ozonn加油e (臭氧层) in the atmosphere, which protn加油ects humans from harmful n加油levels of ultravioletn加油（紫外线） radiation, will be thinnern加油 over the United States thisn加油 summer. The thinner ln加油ayer allows more ultra

26、violet rn加油ays from the sun to reach Ean加油rth. The extra amount of ultravin加油olet radiation could cause ann加油 increase in the number of casen加油s of skin cancer. Scn加油ientists first became concerned aboun加油t the ozone layer in then加油 mid-1980s when a hole was n加油discovered in the layer above Antarcti

27、cn加油a during the winter. The n加油hole was caused by chn加油emicals used in refrigerators ann加油d air conditioners. When these chemicaln加油s are sent out into the atmon加油sphere, they produce gasesn加油 that destroy the ozone. Concern n加油about the protective ozn加油one layer rose more recently when n加油data(数据)

28、 from satellites n加油and ground stations showedn加油 that ozone levels were dropping n加油over areas other than Antn加油arctica. Low ozone levels wn加油ere recorded in the sprn加油ing and summer over the United n加油States and over other pon加油pulated areas in the world. n加油 Although many countries have alrean加油d

29、y begun stopping the use of ozone desn加油troying chemicals, thn加油e new findings are expn加油ected to advance the timetable for an加油 total ban(禁止) of the chemin加油cals.1. The scientists n加油have observed the ozonen加油 layer_.A. since 1980 n加油 B. since last winter n加油 C for about 20 yean加油rs D. for about on

32、d-1980s4. The damage to the ozon加油ne layer was caused by_.A. tn加油he changeable weatherB. on加油zone-destroying chemicn加油alsC. chemicals from refrigeratorsn加油D. chemicals from air condin加油tionersB Early in the mornn加油ing of June 29, 1991, Carrie n加油and Morgenstern weren加油 watching the field. Although t

33、hen加油y could see nothing through the thicn加油k fog, they kept their camera running.n加油 By 6 a.m. the fog began to lin加油ft. A remarkable pair of circln加油es had been flattened. Staln加油ks (主茎) were bent but not brn加油oken. Outside the circles the wheatn加油 was untouched. Muddy though the fn加油ield was, the

34、re were no footprintsn加油 or other marks. The cin加油rcles seemed to have come fn加油rom nowhere. “ I cant explain itn加油 at all ,” Mike Carrier said to himself n加油with his eyes wide on加油pen. Carrier is not alone sn加油ince the early 1980s, more n加油than 2019 circles have appearn加油ed in farmers fields. Most

35、cin加油rcles form at night between May n加油and August. Some believe n加油the circles are caused by deer or sn加油ome other animals. Others thinn加油k of UFOs. “The circles an加油re messages given by those who con加油me from outer space,” says n加油Michael Green. “Perhaps tn加油hey are trying to get in toun加油ch with

36、us.” Pat Delgado has donen加油 research on crop cirn加油cles since 1981. He believen加油s that they are caused by “n加油 some form of earth enen加油rgy.” Most scientists thn加油ink that theres no scientific n加油basis to back up Greens or Delgan加油dos theories. Some of them say, “ We n加油think theyre nothing bun加油t

37、 hoax(骗局).” In Septembn加油er 1991, Doug Bower and Dan加油ve Chorley told newsmen than加油t since 1979 they had made circles tn加油hroughout southern England to foon加油l people who believed in UFOs. Sn加油ince the early 1980s, Dr. Terencn加油e Meaden has visited more than1000n加油 circles. Now he thinks he man加油y

38、have the answer. He believen加油s true crop circles arn加油e made by vortex(旋风) n加油which can flatten the cn加油rop in circular patterns. Now n加油crop circles are still found in southen加油rn England each summern加油. Are they really the traces of UFOn加油s?5. On the morning of Junn加油e 29, 1991, Carrier and Morge

39、nsern hn加油oped to_. A. record n加油the important thing n加油 B. draw a conclusion加油n C. find a secret of naturen加油 D. see sometn加油hing funny6. When he n加油saw the crop circle, Mike Carrie wan加油s_. A. satisfn加油ied B. frightened C.n加油 surprised D inn加油terested7. Most scientists considn加油er that theories of

40、 Green and Deln加油gado are_. A meaningful n加油 B. reasonable C instructive n加油 D. against thn加油e laws of science8. According to thn加油e article we may know that n加油all the crop circles_. A. are mn加油ade by those who come from outer span加油ce B. are nothing but hoaxesCn加油. are not hoaxes n加油 D can be expl

41、ained by scientistsn加油CThe journey to the moon加油n had been the first sn加油tep toward future explon加油ration(探险) in space. The distn加油ance between the Moon and Earthn加油 is very short indeed wn加油hen compared with the distancn加油es between Earth and the othen加油r planets. Mars, the nearesn加油t planet to Ear

42、th is millin加油ons of miles away. Travelin加油ng to the planets will be mans next aimn加油. Such travels will be moren加油 challenging than the trip to the mon加油on and certainly more adven加油nturous. Recently, two Amern加油ican spaceships, Vikings n加油1 and 2, landed on Man加油rs trying to discover whether n加油th

43、at planet has any ln加油ife on it. So far the signs of life n加油on Mars has neither con加油nfirmed(确认) nor ruled out.n加油 Russians have discovered n加油that the surface of Venus(金星) n加油is so hot that it is almostn加油 certain that there is no life there. An加油lso the atmosphere of Venus is extren加油mely dense(稠) and the pressure is nearn加油ly a hundred times grn加油eater than that of the Earths atmosphn加油ere. Scientists believe man may fin加油nd planets which have the same n加
