只看懂了B 😓

E 倒装错误，应该完全倒装，so 放最前。
BCD 没有连词，语法错

提高速度，主谓不一致快速排出AB

Like 作为介词后面只能加名词，不能加句子

A great way to check whether A is correct is to have the two clauses switch places; begin with the main clause "their descendents, popular known as killer bees had migrated as far north as Southern Texas and finish with the subordinate clause "less than 35 years after the release of African honeybees outside Sao Paulo, Brazil". This gives us:

Their descendents, popularly known as killer bees, had migrated as far north as Southern Texas less than 35 years after the release of African honeybees outside Sao Paulo, Brazil.
This is indeed a correct sentence.

D："when" must refer to a time period; "it took less than 35 years" isn't a time period - eliminate.
C："In less than the 35 years" is idiomatically incorrect. The proper idiom would be "In the less than 35 years" - and would change the meaning of the sentence - eliminate.
B："Their descendants" doesn't modify those who did the releasing, so "since releasing" is wrong - eliminate.
E：The whole thing sounds horrible (always a good reason to eliminate a choice), the tenses don't make any sense and "it took less" certainly doesn't go with "and then" - eliminate.
Do NOT use the past perfect in the "since" clause,

根据句意，应该是economic shifts 导致工人工资降低，才会让反贫穷组织反抗。
所以经济转变不应该做从句状语

ADE强调是有余额的账户
B强调的是余额低于某个值

D instead 和of by 两个介词连用错误

split1:

备注一下~

求问，E中的it指代什么呢？

split 1 :A&B: Suppliers are growing fish twice as fast astheir natural growth rate. This sentence has incorrect elliptical usage. This sentence can actually mean either of the following two:

a. Suppliers are growing fish twice as fast as suppliers are growing their natural growth rate.
b. Suppliers are growing fish twice as fast as their natural growth rate is growing fish.

But both these sentences do not make sense and are illogical.
split 2: Rate = speed
Saying “speed is fast” is definitely incorrect.
“Speed is more than something” or “Speed is higher than something” is appropriate
On similar lines, growth rate cannot be faster. Growth rate can be higher.

Passage3的最后一题 #9，答案应该是A吧。Smith和Steuart认为,互惠不仅是人类社会的一个显著的事实,实际上也是一种自然力量——一种会导致市场利益的给予和获得最终平衡的机制

错选了C，还是没有理解题意。C选项的only one指的是theorems的only one，然而正确句意应该指的是mathematicians

这判断方法其实也很复杂啊……多练多少道题才能熟练地用这个方法
