AA “The Saluda Consolidated High School offers over 200 different courses from which its students can choose. A much smaller private school down the street offers a basic curriculum of only 80 different courses, but it consistently sends a higher proportion of its graduating seniors on to college than Consolidated does. By eliminating at least half of the courses offered there and focusing on a basic curriculum, we could improve student performance at Consolidated and also save many tax dollars.” AI B4. Each generation's culture achievements--such as those in music, art ，or literature--represent improvements on the cultural achievements of previous generations. 很惨，作天晚上无意中看到此题，心想明天如果遇到此题甘认倒霉，没想到。。。唉！

3. P is one of the factors of 36, t is one of the factors of 27, which one is the impossible value of P^2-t^2? a.19*17 b. c.39*13 d e.63*9 大概是这个样子，解题思路为P^2-t^2变换为(p+t)(p-t)。我选的是C。

137. 总共有60辆车，两种分类方法：大、中、小；黑、白、红。白车19辆，红车10辆。白车和红车都没有大的。大车有多少辆？ 好像是DS 题，其中有一个条件是大车的数量比中小两种车的总数大。(可能有些出入) 列下表，可见X+Y+29=60，SO X+Y=31。IF X>Y+29, THEN X must be 31 and y must be 0. 大黑 中黑 小黑 中白 中红 小白 小红 设为x 设为y 19+10=29辆
CR 1.The traditional treatment of strep infections has been a seven-day course of antibiotics, either penicillin or erythromycin. However, since many patients stop taking those drugs within three days, reinfection is common in cases where these drugs are prescribed. A new antibiotic requires only a three-day course of treatment. Therefore, reinfection will probably be less common in cases where the new antibiotic is prescribed than in cases where either penicillin or erythromycin is prescribed.
Which of the following, if true, most strengthens the argument? A.Some of people who are allergic to penicillin are likely to be allergic to the new antibiotic. B.A course of treatment with the new antibiotic costs about the same as a course of treatment with either penicillin or erythromycin. C.The new antibiotic has been shown to be effective in eradicating bacterial infections other than strep. D.Some physicians have already begun to prescribe the new antibiotic instead of penicillin or erythromycin for the treatment of some strep infections E.Regardless of whether they take a traditional antibiotic or the new one, most patients feel fully recovered after taking the drug for three days. ANS: E
