前几天做题怎么还看到not, nor的用法 马一下

看到最后看到转折然后选了E, 忽略了前面的not only。
2）时态
3）完整句子

? C: out of 不对结合第2句。
this process [Trying to recover ] is expensive
Intended meaning:
this process [recovering ..[ is expensive.
在A里 It [to recover...] is worthwhile to try

很多都是比较 主语是一个物还是一件事。 这里 result of-》 鸟消失这件事情

感觉老师对于sc的理解是相对语法，句意更重要？

楼下L13548060297这个号称拼课的微信号是骗子，大家注意！！我也是给了钱结果被拉黑了！！！

digits 位数

A:Martin没提到关于hunting的问题，即使Paleoindians were not primarily dependent on hunting for survival,他们还是可以通过hunting导致物种灭绝
C:address the controversy解决争议

这套的第二题，想问问老师答案是不是有错？我在其他平台有看到这道题选B

D. The sentence is set up in present context of time. Thus, use of “could afford” – past tense is incorrect. Similarly, the verb tense “would find” is incorrect. This verb tense should be “would have verb”. This is because the sentence states a hypothetical condition. These appliances did not exist in the times of grandparents. But per the sentence if these appliances had existed at that time, then the grandparents would have found them miraculous. By using “would verb” tense, the sentence now implies that if grandparents saw these appliances being used today, they will find them miraculous.

to XXX extent / the extent of

The population of A (is) 10 times the population of B

xxx of A, B, and C, and yyy ..

E price是charge的直接对象（charge a price），所以不需要再加介词，直接that即可；charge at a price是错的，sell sth. at a price倒是可以的。
补充说明

neither + nor，without xxx or xxx 是正确表达

Whereas 和 in comparison 重复

1） 时态 3.5 removed
2） logic 2
3） 不定式表示强约束力

B主要问题是lower后面需要有than链接被比较词吧，而不是compare with。而且对比对象也不是同一词性。

1） thesis 应该是属于 Shopping for a Better World
2） with 状语从句
