This makes surgery riskier for men. Because they do not breathe

20、as often as women, men also need more oxygen. But men breathe more deeply and this exposes them to another risk. They draw more of the air when it is polluted.Mens bones are larger than womens and they are arranged somewhat differently. The feminine walk that evokes so many whistles is a matter of b

21、one structure. A man has broader shoulders and a narrower pelvis, which makes him stride out with no waste motion. A womans wider pelvis, designed for childbearing, forces her to put more movement into each step she takes with the result that she displays a bit of jiggle and sway as she walks.If you

22、 think a man is brave because he can climb a ladder to clean out the roof gutters, dont forget it is easier for him than for a woman. The angle at which a womans thigh is joined to her knees makes climbing difficult for her, no matter whether it is a ladder or stairs or a mountain that she is tackli

23、ng.A mans skin is thicker than a womans and not nearly as soft. This prevents the suns radiation from getting through, which is why men wrinkle less than women do. Women have a thin layer of fat just under the skin and there is a plus to this greater fat reserve. It acts as an invisible fur coat to

24、keep a woman warmer in the winter. Women also stay cooler in summer. Because the fat layer helps insulate them against heat. Mens fat is distributed differently. And they do not have that layer of it underneath their skin. In fact, they have considerably less fat than women and more lean mass. 41 pe

25、rcent of a mans body is muscle compared to thirty-five percent for women, which means that men have more muscle power. When we mention strength, almost 90 percent of a mans weight is strength compared to about 50 percent of a womans weight.The higher proportion of muscle to fat makes it easier for m

26、en to lose weight. Muscle burns up five more calories a pound than fat does just to maintain itself. So when a man wants to loss weight, the pounds roll off much faster. For all mens muscularity they do not have the energy reserves women do. They have more start-up energy, but the fat tucked away in

27、 womens nooks and crannies provides a rich energy reserve that men lack.Cardiologists at the University of Alabama who tested healthy women on treadmills discovered that over the years the female capacity for exercise far exceeds the male capacity. A woman of sixty who is in good health can exercise

28、 up to 90 percent of what she could do when she was twenty. A man of sixty has only 60 percent left of his capacity as a twenty-year-old.（分数：5.00）(1).That boys suffer more from air pollution can possibly be justified by the fact that（分数：1.00）A.the male have larger bones than the female.B.women can m

29、anufacture blood more efficiently than men.C.men usually breathe more deeply than women.D.women breathe as often as men.(2).The different ways men and women move their body indicate that（分数：1.00）A.bone structures in men and women are arranged differently.B.womens bones are more ready to movement.C.m

31、them easier to lose weight.D.an aged man can still exercise his body as he was young.(4).The best title for the above article is（分数：1.00）A.Why Men Lack Capacity for Exercise over the Years.B.How Mens Bones Are Arranged Differently from Womens.C.Studies on Differences and Similarities between Men and

32、 Women.D.Men and Women: Some Differences.(5).Which of the following statements is NOT true according to the passage?（分数：1.00）A.More oxygen needs to be prepared when a man is having surgery.B.Mans courage has nothing to do with males body structure.C.A woman usually stays cooler in summer and warmer

33、in winter.D.It is easier for a man to lose his weight.BPassage 2/BMore than 30, 000 drivers and passengers who sit in the front of the vehicles are killed or seriously injured each year. At a speed of only 30 miles per hour it is the same as falling from a thirdfloor building. Wearing a seat belt sa

34、ves lives: it reduces your chance of death or serious injury by more than a half.Therefore drivers or front seat passengers over 14 in most vehicles must wear a seat belt. If you do not, you will be fined up to 50. It will not be up to the drivers to make sure you wear your belt. But it will be the

35、drivers responsibility to make sure that children under 14 do not ride in the front unless they are wearing a seat belt of some kind.However, when youre reversing your car, you do not have to wear a seat belt; or when you are making a local delivery or collection using a special vehicle; or if you h

41、rst navigational lights in the New World were probably lanterns hung at harbor en- trances. The first lighthouse was put up by the Massachusetts Bay Colony in 1716 on Little Brew- stet Island at the entrance to Boston Harbor. Paid for and maintained by “light dues“ levied (征收) on ships, the original

42、 beacon was blown up in 1776. Until then there were only a dozen or so true lighthouses in the colonies. Little over a century later, there were 700 lighthouses.The first eight lanterns erected on the West Coast in the 1850s featured the same basic New England design: a Cape Cod dwelling with the to

43、wer rising from the center or standing close by. In New England and elsewhere, though, lighthouses reflected a variety of architectural styles. Since most stations in the Northeast were set up on rocky eminences (高处), enormous towers were not the rule. Some of them were made of stone and brick, othe

44、rs of wood or metal. Some of them stood on pilings or stilts; others were fastened to rock with iron rods. Farther south, from Maryland through the Florida Keys, the coast was low and sandy. It was often necessary to build tall towers there - massive structures like the majestic lighthouse in Cape H

45、atteras, North Carolina, which was lit in 1870. 190 feet high, it is the tallest brick lighthouse in the country.Notwithstanding differences in construction appearence, most lighthouses in America shared several features: a light, living quarters, and sometimes a bell (or later a foghorn). They also

46、 had quarters, and something else in common: a keeper and usually the keepers family. The keepers essential task was trimming the lantern wick (灯芯) in order to maintain a steady, bright flame. The earliest keepers came from every industry - they were seamen, farmers, mechanics, rough mill hands - an

47、d appointments were often handed out by local customs commissioners as political plums. After the administration of lighthouse was taken over in 1852 by the United States Lighthouse Board, and agency of the Treasury Department, the keeper corps gradually became highly professional.（分数：5.00）(1).Which
