OG18-720-错
介词短语修饰的位置、句子完整
A over the past twenty years修饰了knowledge，变成定语;应当修饰动作更为合理——但这里似乎可以接收
B句子不完整，Neuroscientists缺谓语；且over the past 20 years 变为修饰development，改变句子意思
C 同B，缺谓语；且over the past 20 years 变为修饰development，改变句子意思
D把主干变为修饰；drawing可能被误读成修饰adulthood
E 同D

VERB 吃;喝;饮用
If you consume something, you eat or drink it.
VERB 消耗，耗费(燃料、能源或时间)
To consume an amount of fuel, energy, or time means to use it up.
这个词理解错了......

考察：虚拟语气、比较结构
A. 比较结构为level higher (is) than were emissions
不合逻辑，且如果than前无be动词，than后最好也不要有were
B. 比较结构为level (is) higher than level (was)
合理
C. 想讨论的是真实情况，不该用虚拟语气。
D. 同C，those指代emissions不合逻辑
E 同C， they完全指代emissions不合逻辑

考查要点是代词和比较结构
A Since 1990 the global economy has grown more than it did during the 10,000 years from the beginning of agriculture
比较结构是the global economy has grown more than the global economy(it整体指代) grew
合理
且后面from...to...也是平行结构，beginning和1950相较于when和1950更好
B Since 1990 the growth of the global economy has been more than that during 10,000 years,from when agriculture began
错选B
比较结构是the growth of the global economy has been more than the growth(that) during 10,000 years is
根据Ron所说，that+prep在比较结构中最好严格与前方平行，所以前方也应该有growth during之类的对照
其次，the growth is more than growth is 并不好，不如faster than the growth is
最后，when和1950不如beginning和1950平行

C The growth of the global economy since 1990 exceeds that which had been for 10,000 years from the beginning of agriculture
没有使用had been的标志词；
which不能不加“，”,除非是介词+which的形式（存疑）
had been与前半句无对应，应该是前半句有be的内容，后半句才能有had been这种省略

D\E中it完全指代，后半句根本不成逻辑

考察核心语意、平行结构。
A：应该是impact it will have；
B：核心语意变为：whether warming will be significant更改了原句的意思；而且whether从句和impact并不平行
C: 不应该用or；if从句后不能用did（主将从现）
D：不应该用or；而且whether从句和impact并不平行

D选项为什么可以从恐龙上面获得骨头？应该是从恐龙尸体上获得骨头才对吧，所以才选了E
这题如果from 修饰found了，觉得不合逻辑

B的问题是 in 1959 放在了两个并列动词 won and was 前面，只能共同修饰这两个动词；而放在第一个动词后面，使用and隔开，won in1959 and was则只修饰第一个动词。所以逻辑上判断这个时间状语修饰谁就可以了。明显后面的was later指的是1959之后，won award 指的是1959.因此这个时间只能放在won 之后。

The H puts on XXX, But( it (has no fangs And No venom), And( wll fall over And play dead))

use of by is improper in an active voice setting. It should be with the animal rather than by the animal

关键是比较修饰对象，比较的是名词还是动作。

第一个比较 price is higher this year than (that is) last year. "higher 修饰的是price，比较名词" 或者改成 the price rise higher this year than the price did last year —— "higher修饰的是rise，比较的动作"
第二个比较：are paying $5 more than they were (paying last year) 或者 pay $5 more than they did ——more 比较的pay 这个动作，所以比较 were 或者 did

make someone do sth

没有选D的主要原因是语境。与A比较，A的主句强调EBB被她老公超越一事。D的主句反而强调了EBB是同时代最优者。
