放小狗

Gillian625 · 发表于 2018-3-13 19:50:24

狗主家所在的城市没有考点，今天去省会城市考的，刚刚下高铁回到家就来CD放狗，虽然自己这次分手失败，但是希望能对今后几天考试的朋友一些帮助，顺便攒人品~

数学：
1. the product of the first N consecutive 正整数等于一个数，这个数末尾有6个0，求N的最小值是多少。选项是25,30,35,40。狗主选的30。

2. 图在图片中。ABC三个城镇的位置构成一个直角三角形，A到B 45miles，B到C 60miles。一个人从A到B，再从B到C，速度是80miles/h。第二个人直接从A到C，速度是60miles/h。问谁的用时长，用了多长时间？

3. 图在图片中。正方形上面有个圆形，正方形的边长=圆形的直径=2cm，问阴影部分的周长。

4. DS题。有四个人坐成一排，要求第一个人和第四个人的性别相同，问有多少种可能性（或者概率是多少，记不清了）
条件一：至少有一个男的
条件二：失忆...

阅读：
一篇是hightech创新和drug，一篇是药厂genetic product。还有一篇是关于维生素C能不能延长人的寿命的（我记得在之前的鸡精里面看到过），文章很短，大概三分之二屏，两段。

逻辑考了一道OG还是Prep的原题，是关于sea otter sea lion，killer whale的那道。

作文考的是说近几年人们对mining行业的需求下降，导致B公司利润和股价下降。有人建议B公司应该转向renewable行业，进行renewable technology的研究，举例说有一些renewable的公司就很成功。所以B 公司如果转型到renewable行业，利润和股价就不会再下降。

Inthe late 1980s, the population of sea otters in the North Pacific Ocean beganto decline. Of the two plausible explanations for the decline — increasedpredation by killer whales or disease — disease is the more likely. After all, aconcurrent sharp decline in the populations of seals and sea lions was almostcertainly caused by a pollution-related disease, which could have spread to seaotters, whereas the population of killer whales did not change noticeably. Whichof the following, if true, most seriously weakens the reasoning? A. Killer whales in the North Pacific usually prey onseals and sea lions but wil, when this food source is scarce, seek out otherprey. B. There is no indication thatsubstantial numbers of sea otters migrated to other locations from the NorthPacific in the 1980s. C. Along the Pacific coast ofNorth America in the 19805, sea otters were absent from many locations wherethey had been relatively common in former times. D. Following the in the populationof the sea otters, there was an increase in the population of sea urchins,which are sea otters ’ main food source. E. The North Pacific populationsof seals and sea lions cover a wider geographic area than does the populationof sea otters.
是这个吗
