but后面加句子，AB错误
only if后主将从现，不用虚拟语气，因是真的可能发生

not so much/as:
as/as即可用于肯定句，也可用于否定句；not so/ as只能用于否定句；
not so much A/as B，与其说是……，不如说是，相当于rather than。可以变形为 not so much A/but B或 not A, so much as B
not so much A/as B可以跟名词/形容词/短语/句子，要求连接对象平行。

synchronize vt.使同步
不能是movement主动去同步音乐，只能是人才能去主动同步音乐，应该是movement（被）和音乐同步

A. bones 是 large prehistoric animals，错误
BD. 名词+Known/assume as（介词）+名词（名称） 名词+Known/assume to be (系动词) +名词/形容词（性质），故错误
DE. those of the remains of 错误

计算错误

E错在where的修饰对象变成了electricity
单看修饰对象的正确与否，应该选择A（，非限定定语从句与修饰对象要尽量靠近）

A，she shattered expectations more audaciously than.....had been,显然shattered 和had been应该是对应的
;应该是had done而不是had been
appoint sb. sth.
根据逻辑主语先排除BC，A中had been和shattered不平行，排除A
E中 WRONG---- sb. be appointed to be/as sth; WRONG-----either in the case of sb. or of sb's

But clinging to this ideology also prevented these women from even attempting to gain true political power because it implied a moral purity that precluded participation in the messy world of partisan politics.

本题讲的是“没有被预见到的天气条件”，而不是“那些不具备可预见性的天气”，故B正确D错误

一定要搞清时间状语是在修饰什么，不是修饰projected或者estimated，这样变成了到了年代末才开始预测，而是应该修饰cost will be 10%。
且表达未来的预测时候，一般用estimated/projected to be，而不是estimated/projected at
A. cost... is projected ...by the end of the decade. 时间状语位置错误，变成修饰projected这个动词，错误
B. cost of meeting....可以接受，更像是在这个meeting的过程中，产生的cost，而cost to do更像是cost被预测到10%，然后meet了regulation，故正确
C. is时态错误，而且by the end of the decade依旧在修饰projected，变成了到年代末才开始projected，错误
D. 时间状语错误同A，且语意变成了cost被估计到10%是为了meet regulations， 但实际应该是因meet regulations而产生的costs。错误
E. cost (by the end of the decade) to meet environmental regulations. cost to meet regulations 更紧密，应该放在一起，错误

CDE主谓不一致
A选项应该是it can be spent only on...not on...
B选项demand命令后面接虚拟语气schould省略

AD. rates和immigrant group比较，错误
B. "exceeding virtually every other immigrant group“作为"rates of entrepreneurship"的modifier，错误
E. rates ... exceeds，错误

是passage发生在1999，要就近修饰

neurogenesis：the growth and development of nervous tissue.

D选项when placed in a stimulating environment的主语是brain growth，错误

a）possibly resulting from修饰的是were suffering，逻辑不对，应该是海温度上升导致食物供给变坏，食物供给变坏导致生物suffer
b）possibly resulting from修饰的是were dwindling，ok

the ones通常用于指代“前面出现过的”一堆人或物种的几个，错误，应该用those代指被蜜蜂杀死的人

由于n^3是整数 所以 y=2^2 *3 *5 * (k^3)
