9. The following appeared in the opinion column of a financial magazine.
“On average, middle-aged consumers devote 39 percent of their retail expenditure to department store products and services, while for younger consumers the average is only 25 percent. Since the number of middle-aged people will increase dramatically within the next decade, department stores can expect retail sales to increase significantly during that period. Furthermore, to take advantage of the trend, these stores should begin to replace some of those products intended to attract the younger consumer with products intended to attract the middle-aged consumer.”
财经杂志的意见栏：
一般而言，中年消费者的零售消费额的39％用于专卖店的商品何服务。而在年轻一些的消费者中这一比例仅有25％。由于中年消费者的数量在下一10年中将大幅增长，专卖店可以预期他们的销售额会有大幅增长。进一步，为利用这一趋势，这些店应该开始将一些吸引年轻消费者的商品替换为吸引中年消费者的商品。

一篇：动物警惕性--动物警惕性随着group size的增加而减少的。两种解释：一个学者说因为group增大，发现捕食者的机率就大，所以有更多时间feed。（这里有题，问如果是个体与群体比较有什么区别，选个体feed的时间少于群体）另一个学者的观点是说，因为group大，那么里面的每个个体被捕食的机率就小了。最后作者说，其实也有可能有更多的原因导致警惕性下降，比如，某个群体feed后代很好，就会吸引更多的个体加入，这样群体会花很多时间在提高生存质量上，所以忽略了。。。（大概是这个意思，翻译得不准确）

A) Deep events are far less common than shallow events.
B) Deep events occur in places other than where crustal plates meet.
C) Mantle rock is more ductile at a depth of several hundred kilometers than it is at 50 kilometers.
D) The speeds of both P and S waves are slightly greater than previously thought.
E) Below 650 kilometers earthquakes cease to occur.
2） Information presented in the passage suggests that, compared with seismic activity at the epicenter of a shallow event, seismic activity at the epicenter of a deep event is characterized by （E）
A) shorter P-S intervals and higher peak intensity
B) shorter P-S intervals and lower peak intensity
C) longer P-S intervals and similar peak intensity
D) longer P-S intervals and higher peak intensity
E) longer P-S intervals and lower peak intensity
3）The passage supports which of the following statements about the relationship between the epicenter and the focusof an earthquake?（D）
A) P waves originate at the focus and S waves originate at the epicenter.
B) In deep events the epicenter and the focus are reversed.
C) In shallow events the epicenter and the focus coincide
D) In both deep and shallow events the focus lies beneath the epicenter
4）The method used by Wadati to determine the depths of earthquakes is most like which of the following? (C)
(A) Determining the depth of a well by dropping stones into the well and timing how long they take to reach the bottom

一篇：夏威夷发展的测定
q1有两个选型比较混淆：一个说文章是用新的科学技术证实了一个地区的历史；另一个选项是说，文章证实了口述者的话，并让人们对于某个地区的了解更正确了。我选的后者，因为没有说明是新发明的科学技术。
q2 serve one generation 的作用。我选：这个文明结构比原想的更ｕｎｅｖｅｎ．

1.Ｌａｒｇｅ农场有某种物质，会释放某种有害物质（都是生化类词汇，看不懂，但可以忽略，用首字母表示就可以了~）．提出一的方法，在实验室５０％有效等等．因此在实际中会取得成功．选项 这种方法在大农场效率不会降低．
2.由于手机越来越多，很少人现在使用飞机上的电话，但因为电话维护费由电话公司承担，航空公司从通话费中抽取部分收入，因此飞机上的电话还是有利可图，问假设？飞机电话的重量不会影响到使用燃料的效率
3.科学家做实验，让两组人去思考思考，然后对某问题做出决定。期间对第一组人在思考时搞了点小杂事，为了扰乱第一组人连贯的思维。第二组人在思考时没有进行打扰。结果出来却发现第一组人做出的决定更好。于是科学家认为在思考中如果大脑发生了非目的性思考的潜意识，那么这样情况下做决定的效率更高。问前提。答案：第二组人在进行连贯思考时大脑没有产生非目的性思考的潜意识。
4.保险公司对于火灾和洪水的赔款相同，但收取火灾的保费比洪水的低很多。排除灾难中财产损失多少不考虑，保险公司还是坚持这样做。问（忘记是weaken还是evaluate了），总之选因为保险公司能从别的项目中长期获利。

讨论得轰轰烈烈的录音机当电话那样私人通话的工具的那道题。
本来我想算了，但在考试之前还是问了几个牛人，确认了一下答案，没想到真的考到了！!(人品大爆发啊~）
最后的答案选E（这个答案是问了几个native American 和一个新东方的老师给出的，应该是没有什么问题的吧。搞笑的是，native们都说，that’s too hard, we really don’t know the reason, just because it sounds better…个人觉得，c选项有点改变了原句的意思，所以不对。）

暂时想起这么多，后面再补上，因为现在脑子已经一团浆糊了。。。
其实今天真的算是超水平发挥，特别是verble部分。（因为我从小就是超级数学白痴，46的数学我已经很满足了。给中国人丢脸了啊。。。
）
不过我最想说的还是，6天以前我做prep只有500多分的，（当时就想死了算了），但是结果却出乎意料。所以prep不一定准的啦，大家不要太在意模考得结果。最重要的是，坚持！HOLD ON！总会过去的~当然还要感谢JJ，because we are fighting together, miracle occurs.
