讨论的是事实，所以一般现在时

要看得懂题，关键！！！

考察：句子完整，核心语意
A.which修饰paralysis，不能跳跃“，”修饰inactivity; lately应该修饰making things even more difficult，位置不对
B.there 前面无“，”，相当于有两个主语；it has provided与前面无连接词
C.general前面无“，”，相当于两个主语
D.正确
E.that从句中无谓语

weather permitting, we will play football tomorrow.

all things considered, it's a good idea.

this being the case, let's go.

如果比宾语circulation，那么比较级lower应放在主句之后，即宾语后面；所以这里比的不是circulation，那么D选项中的that指代circulation将毫无意义。

考察了平行和比较结构，已经定语从句的修饰
A：比较结构a land area is the same as GB is，地和国不能比
且where不能修饰population
B：比较结构 a land area is of about same size as GB is，还是地和国比，虽然比的是面积勉强可以
but和and的使用变更了原句的意思；many指代不清
C：比较结构a land area is about same size as GB is，还是地和国比，虽然比的是面积勉强可以
but后核心词变为many of them如何如何，不构成转折关系
且many of them不同于many of whom，不能作为从句，导致成分残缺
D：比较结构a land area is comparable to size of GB，地和面积比
and many与前句割裂，
E：正确

这题正确答案应该是E。

老师的解释里，C错的地方是Consequently 和 therefore是重复的，这才是错的关键。

A选项错的关键是 protects the buds from which blah blah, 这里的from是有歧义的。是protect sth from sth，还是 from which呢?

E中的becasue 和 as a result作为赘余是很牵强的解释。在语法上是没有任何问题的。

I have less money than you (have).

其实已经确定了so2都被过滤了，a选项错

cut cut cut
trenches cut into ...have yielded evidence that societies arose simultaneously (with) but independently (of) city states.

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
