For three decades weve heard endlessly about the virtues of aerobic (increasing oxygen consumption)exercise.Medical authorities have praised running and jumping as the key to good healthand millions of Americans have taken to the treadmill to reap the rewards.But the story is changing.Everyone from the American Heart Association to the surgeon generalS office has recently embraced strength training as a complement to aerobics.And as weight lifting has gone mainstreamSO has the once obscure practice known asSuper Slowtraining.Enthusiasts claim that by pumping iron at a snails pace——making eachrep(repeat)last 1 4 seconds instead of the usual 7you can safely place extraordinary demands on your musclesand call forth an extraordinary response.Slow lifting may not be the only exercise you needas some advocates believebut the benefits are often dramatic.

Almost anyone can handle this routine.The only requirements are complete focus and a tolerance for deep muscular burn.For each exercise——leg pressbench pressshoulder press and SO On70u set the machine to provide only moderate resistance.But as you draw out each repeatdepriving yourself of impetusthe weight soon feels unbearable.Defying the impulse to stopyou kegoing until you cant complete a repeat.Then you sustain your vain effort for 1 0 more seconds while the weight sinks gradually toward its cradle.Intense? Uncomfortable? Totally.But once you embrace muscle failure as the goal of the workoutit can become almost pleasure.

The goal is not to bunr calories while you\'re exercising but to make your body burn them all the time.Running a few miles may make you sweatbut it expends only 1 00 calories per mileand it doesnt stimulate much bone or muscle development.Strength training doesnt burn many calorieseither.But when you push a muscle to failureyou set off a pour of physiological changes.As the muscle recovers over several daysit will thicken——and the new muscle tissue will demand sustenance.By the time you add three pounds of muscleyour body requires an extra 9000 calories a month just to break even.Hold your diet steady andvery quicklyyou are vaporizing body fat.

One might have benefited from any strengthtraining program.But advocates insist the slowtechnique is safer and more effective than traditional methods.

参考答案:

1. D细节题。根据题干关键词仃eadmiu定位文章第一段,第二句提到美国人喜欢练脚踏车是为了reaDthe rewards(得到报偿),由此可知D“从运动中获得实际的好处”最符合题意。其余三项A “与生俱来地对他们健康有好处”,人在跑步机上运动才会对身体有益,而不是跑步机本身对健康有益,可排除;B“由于跑步机耗氧量大”,跑步机耗氧是为了锻炼身体,但并非最终目的,排除;c“由于受到权威的赞美”属于偷换概念,因为文中提到受称赞的是running and jumping,也排除。

2. B推断题。根据题干关键词super slOW定位文章第一段,其中提到“同举重运动一样,一度默默无闻的‘超慢速’运动也已成为了主流”,可知B说法最恰当。A中的misunderstood是对 obscure(模糊的,不引人注意的)的有意曲解;c的内容在文中并未提到;D言过其实,文中只说strength training(力量锻炼)a complement to aerobics(有氧健身运动的一个补充),但没有说“Super.S10wtraining成为有氧运动的核心,故排除。

3. c推断题。题干关键词slowling(慢速举重)最先出现在第一段最后一句,随后第二段进一步描述该运动要求高度集中的注意力和对肌肉灼伤的忍耐力。选项A中所说的“给肌肉施加巨大的负荷”,不同于文中的“对肌肉灼伤的忍耐力”,二者程度不同;选项B在文中并未提及, D说的是举重锻炼的不同部位而非slowlng的要求,因此C“忍受由于练习所致的肌肉疼痛”符合文意。

4. A细节题。由题干中的信息词make each rep定位第二段第四句“但由于你每次重复动作时动量 逐渐减少,重量很快就会显得无法承受”。由此可推知,慢速举重者可能会面临动量损失的情况,故选项A最符合题意。B文中未提;C与文中提到feel unbearable相反、D与文意相反。

5. D语义题。由题干定位第三段“当你增加了3磅肌肉的时候,身体为了 ,每个月就需要额外的900()卡路里”。结合选项,AB均指“打乱身体能量平衡”,实际上大量的运动已经使身体能量不平衡了,无需再打乱平衡,故两者均可排除;c“盈余”,结合常识可知,这根本不利于健康,可排除;D“收支平衡”即保持身体能量平衡,符合题意。

与细胞水肿最密切相关的细胞器是
a.内质网 B.溶酶体 c.线粒体 d.微管

答案:C
解析:
①细胞水肿是因线粒体受损,ATP生成减少,细胞膜钠泵功能障碍,导致细胞内水和 Na+积聚过多所致。镜下改变以线粒体肿胀最明显,内质网肿胀次之。②细胞坏死以酶溶性改变为特征, 属于不可逆损伤。炎症时渗出的中性粒细胞释放溶酶体酶,溶酶体释放酸性水解酶降解细胞成分,是细 胞不可逆损伤的主要超微结构改变。
