7．I am really grateful to Mr．Smith．Without his help，I _______ the entrance examination．（　　）

	A．	would not pass		B．	would not have passed
	C．	could not be able to pass		D．	could not pass

分析我真的很感激史密斯先生，如果没有他的帮助我不可能通过入学考试．

解答 B 考查虚拟语气．根据句意：如果没有他的帮助我不可能通过入学考试．可以推断我已经通过考试，是过去时，所以主句用would+have done结构，故答案选B．

点评虚拟语气是高考经常考查的内容，也是英语学习中的一个难点．虚拟语气用于表示说话人的假想、建议或主观愿望，所表示的假设并不是事实，而是不可能或是不大可能发生或实现的，除了掌握if条件句引导的虚拟语气之外，还要掌握一些与虚拟语气有关的固定句型结构，首先，判断是否需要使用虚拟．其次，结合虚拟语气句式，判断需使用何种时态及句式是解题的关键．

17．We've all seen them：perfectly toned famous people on late-night television telling us that we too can develop rock-hard abdominal muscles（腹肌）．It's easy!Just pay﹩149.99 for the Torso Track or﹩149.75 for the Ad-Doer and watch those unwanted inches leave your waist．Americans spend tens of million of dollars on various products to firm up their fat around the waist．
And did they work？Not necessarily．Independent studies have concluded that most of these products-no matter who approved them or how expensive they are-shape your midsection no better than old-fashioned stomach crunches（仰卧起坐）．Some can even cause injury-like the﹩518.99 Body Shaper-Q8SP，which left electrical burns on some researchers at the University of Wisconsin，La Crosse．Others，like the popular Ab-Doer，trpically burn less energy than a gentle walk，according to a study to be published in September by the American Council on Exercise．
The fact is that many Americans don't have the biological makeup to develop an obvious abdominal muscles．They are either unable to get the necessary muscle mass or they can't lose enough fat to make a difference．Even if the underlying muscles are well developed，and it takes to hide it is one-sixteenth of tan inch of fat．That's enough to dismiss most healthy women as well as plenty of guys who do crunches every day．
So what works best？In its new study，the exercise experts researched on the results of the popular Ab-Doer．A lengthy TV advertisement promises that just 10minutes a day performing such movements as"Body Boogies"and"Good Mornings"will"help form those muscles the fun and easy way without diets．"Steven Loy，professor at California State University，Northridge，tested the promise by measuring the electrical activity produced by the abdominal muscles during three Ab-Doer movements．He and his colleagues then compared the results with those produced during traditional exercises．They determined that the muscles were no more active，and in some cases less so，when exercisers were using the Ab-Doer．
Taking a broader approach，researchers at San Diego State University compared 13abdominal exercises for their ability to develop the central abdominal muscles．They concluded，in a report published in May，that the most effective exercises kept turning the body and worked the muscles the entire time．Among the winners：the bicycle movements-so called because it looks as if you are riding a bike while lying flat on the floor-and exercises performed on the"Captain's Chair"，a product typically found in gyms that helps hold the body in the air while you raise your legs up toward your chest．Researchers suggested that a varied routine of the different exercises could deliver the best results．
