比较的题永远做不对，做对了也是靠别的点做的。感觉是他说可以省略就可以省略，他说意思清晰就意思清晰

可以解释一下D选项中that was not successful的主语为什么不正确吗？D选项中不可以attempted later...和that was not successful都做an achievement的定语吗？

由于本题的问题问的是方案，所以是方案推理。

D 选项的 “with a buttressed trunk and with a crown that spreads over the canopy of lesser trees.” 是独立主格么？

since只能表示现完，bc排除。d中when不对，排除。e中it took后面都没讲清楚，排除

这里是倒装，alphabets were derive from

natural grow不能让they（fish）成为grow的宾语

可是方案推理的话，觉得D选项并没有在谈论这个方案啊，感觉只有A选项有讲到这个方案诶……方案推理的3个CQ不是都要讲到方案才可以吗？(..•˘_˘•..)

果因感覺真的要想一下，想問老師為何不是「因为这个年份很容易被抄写成1460年，所以The testament其实是1409年出版的」

定位第一段最后一句话： Since then, the answer given to the fundamental 【basic】question of who the recipients should be—the most economically disadvantaged or those with the best prospects for business success—has changed, and the social goals of the programs have shifted, resulting in policy changes.

定位第一句话：Colonial historian David Allen's intensive study of five communities in seventeenth-century Massachusetts is a model of meticulous scholarship on the 【detailed】 microcosmic level, and is convincing up to a point【在一定程度上可信】.

X =40到60的全部偶数的和
Y =40到60的全部偶数的数量
X= 40+42+44+46+48+...60 =550
Y = 11

13.5-2*1.5=10.5

一共15个整数各不相同，中位数是25，那么第8个数就是25，那么最小数的最大取值是25-7=18，最大数=最小数+Range 25=18+25=43

The second "there are..." isn't strictly necessary. Without it, you'd have a sentence with the same structure as "In most countries, there are as many men as women."
Its primary value lies in making the sentence easier to read.
This is not an issue of right and wrong"”it's a style issue"”and so it will never be dispositive in a real problem. Still, you should know it's a thing.

奇怪....为什么我的note发送上来都不是完整的? 小于号，等号都不能显示了：（

n>20+2.5*3 or n27.5 or n选A

n>20+2.5*3 or n27.5 or n

here's a simpler illustration of what is going on here:

suzy weighs far less than tom does.
suzy weighs far less than does tom.
suzy weighs far less than tom.
all of these sentences are correct -- including the last, since there's no ambiguity.

suzy weighs only 120 pounds, far less than tom.
--> this is the same essential construction as the third example above.

However是连接副词。however不能像 but(但是)那样直接连接两个句子(注意正句中的标点符号).如：
我们都已尽了最大的努力,不过我们还是输了..
正：We all tried our best,but we lost the game.
正：We all tried our best; however,we lost the game.
正：We all tried our best.However,we lost the game.
