8-22上海[转自我看jj]

8-22上海
先贡献机经:
ai: most people would agree that buildings represent a valuable record of any society's past, but controversy arises when old buildings stand onground that modern planners feel could be better used for modern purposes.(孙远78)
aa:the construction last year of a shopping mall in downtown oak city was a mistake. since the mall has opened, a number of local businesses have closed, the downtown area suffers from an acute parking shortage, and arrests for crime and vagrancy have increased in the nearby oak city park. elm city should heed the example of the oak city mall and deny the application to build a shopping mall in elm city.(孙远103)

考试时状态挺好的,考前睡眠也不错,很感谢我的男友考前帮我进行分析、复习。因为平时数学总拿不到满分,考试时就特别细心,可是矫枉过正,只提前2-3分钟做完数学,还好满分对得起自。本来最轻松的数学浪费了不少脑力,感觉蛮累的,建议大家ds细心点,ps不要反复验算,数学搞疲劳了,对verbal蛮影响的,我做verbal时,感觉脑子反应有点迟钝,不过verbal我从头到尾感觉都比较一致,没感觉难也没觉得简单,可是分数很不理想。

准备休息2天,再战!
