(A) Like humans and other warm-blooded animals, researchers report that the lotus has the remarkable of keeping its
temperature in a narrow range.
(B) Researchers report that within a narrow range, the lotus has the remarkable ability to keep its temperature like humans
and other warm-blooded animals do.
(C) Researchers report that the lotus has the remarkable ability of keeping its temperature to a narrow range, as humans
and other warm-blooded animals can.
(D) Researchers report that the lotus has the remarkable ability to keep its temperature within a narrow range, as do
humans and other warm-blooded animals.
(E) As humans and other warm-blooded animals can, researchers report that the lotus has the remarkable of keeping its
temperature in a narrow range.

请教一下，这道题C为什么会错呢。

brand name并不是透过价格战把顾客吸引回来，而只是想要缩小price gap（还是比store brand贵），所以相比之下B比D更能直接削弱，因为B 消费者已经满意store brand了，除非有更便宜的（像当初被store brand吸引过来？）不然就不太可能买name brand了。D选项只有说store brand有能力让price gap继续保持

rare migratory birds是稀有的候鸟而不是很少迁徙的鸟

找两黑和结论的关系，第二黑就是结论本人，第一黑应该是一个context
错选E，第二黑是结论，应该看到acknowledges就可以删掉了，结论词只有conclusion / position

要想到质因式分解，如果把30和45分解就会发现无论哪个数，最小公倍数都是90

看成立体+1，算了好久没算出来，平面的话做调辅助线底乘以高就可以算出来了

含有绝对值的直线，需要画图辅助求解
（1）|x|+|y| =1图像是个菱形，pq两个点可以在任何线上，斜率不固定
（2）|x+y|=1图形是两条平行的直线，pq只要在不同的直线上斜率就不固定

题干中的hypotenuse的意思是“直角三角形的斜边”，所以相当于告诉了我们三角形ABC是直角三角形。
条件1充足
条件2最终求出一个表达式有两个未知数，不充分，所以不选

Hypotenuse是特指直角三角形的斜边

【引用】
假设width为m, then length=m+y
已知条件：m+m+y=2m+y=x/2, 求m(m+y)-x^2/16,
带入已知条件x^2/16=(2m+y)^2/4, 求的式子变为m^2+my-(4m^2+4my+y^2)/4, 抵消掉相同项只剩下-y^2/4, 只要知道y即可
题目有的条件要列出，并统一求解-->新构成的长方形中的长比宽多y

简单题先列出计算公式：1/2*Π*d；条件2直接给出了直径的和，所以直接计算即可，无需单独求出每个圆的直径！！！

lengths of the legs of a right triangle are integers,
求解该题有两个限制条件：1.直角三角形 2.边长都是整数；所以条件2可以求出唯一的直角三角形

and then determined a selling price that equaled the purchase price of the jacket plus a markup that was 25 percent of the selling price
根据题意可以列出一个等式：sales=60+0.25sales;因此可以求出sales=80

1.60 percent discount=打四折，即0.4x
2.【引用：重要】what percent (more or less) of the selling price in Store N is the selling price of the item in Store W？
简化成what percent is the W，既W is what percent more or less of the selling price in N?
percent of后面接的是分母

mark
1.根据总数算出每个颜色所需要的gallon/quart数量
2.根据每gallon/quart的价格得出尽量买gallon，零头有quart买
Blue1.8g=7.2q
White1.2g=4.8q
12/q(48/g)和18/g,尽量用加仑买，零头用夸脱买。
blue直接买2加仑划算，white买1加仑和1夸脱划算。

看清题意，题目要求的是和一月份（1）最接近的sales的月份；三月0.935，五月1.0098；对比下来五月份离一月份的数字更接近

求的是现在时间比原来时间节省了百分之多少！！

题干看错了，不是300内写了多少个五，而是前300个五的倍数，所以是1500以内写了多少个5...

两天是到第二天结束，不是第二天的一半就可以开始，题目要理解对
