考的一般般,M拿了满分,但V终因阅读能力有限而败。 机经: AWA: AI 62. “What education fails to teach us is to see the human community as one. Rather than focus on the unique differences that separate one nation from another, education should focus on the similarities among all people and places on Earth.” AA 105. The following appeared in an editorial from a newspaper serving the town of Saluda. “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 80different 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.” Math 数列45,49,....V(n)....
