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，如果沒有他的幫助我不可能通過入學考試．

解答 B 考查虛擬語氣．根據(jù)句意：如果沒有他的幫助我不可能通過入學考試．可以推斷我已經(jīng)通過考試，是過去時，所以主句用would+have done結(jié)構(gòu)，故答案選B．

點評虛擬語氣是高考經(jīng)常考查的內(nèi)容，也是英語學習中的一個難點．虛擬語氣用于表示說話人的假想、建議或主觀愿望，所表示的假設并不是事實，而是不可能或是不大可能發(fā)生或?qū)崿F(xiàn)的，除了掌握if條件句引導的虛擬語氣之外，還要掌握一些與虛擬語氣有關的固定句型結(jié)構(gòu)，首先，判斷是否需要使用虛擬．其次，結(jié)合虛擬語氣句式，判斷需使用何種時態(tài)及句式是解題的關鍵．

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�。甀t'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（仰臥起坐）．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．

63．Which of the following is the most effective in building abdominal muscles？C
A．Torso Track．
B．Ab-Doer．
C．Captain's Chair．
D．Body Shaper-Q8SP．
64．According to the author，it's difficult for many Americans to get visible firm abdominal muscles mainly becauseD．
A．they do not put in enough efforts
B．injuries interrupt their exercise frequently
C．they change their exercise routine regularly
D．how big their muscles will be is determined by birth
65．The author convinces the readers byC．
A．describing successful eases
B．offering professional connects
C．presenting findings of researches
D．comparing advertisements of products
66．What's the main purpose of this passage？B
A．To research and develop in order to create the perfect stomach and exercise machine．
B．To promote proven exercise techniques and to advise against false advertisements．
C．To indicate that diet and exercises are necessary factors for a fit midsection．
D．To sponsor rich healthy lifestyle based on advanced product research．
