do sth for sb/ sth可以表示目的，如：She works hard for success.=She works hard to achieve success.； do sth for doing sth不能表示目的，只能表示原因或用途
cooperates with governments to improve access VS cooperates with governments for improvements of access选前者，一个是动词和名词的区别：动词表示事情尚未结束，名词表示事情已经确定，句子里与政府合作来提高通道，提高通道这件事尚未发生，动词比名词好；另外，限定符+形容词+名词构成名词词组，其中限定符不能省略。抽象名词/复数名词前不能加a/an，加零冠词，专有名词前不加限定符。improvements作为复数名词，不加a/an，但因为后面跟了of access，表示是通道的提高，而不是其他的提高，前面应该加定冠词the，for the improvements of access

坑爹啊 数学题一枚。。。画图秒解决

反身代词：
反身代词作代词，表示先行词对自己实施了一个动作，如：After the agreement surfaced, the commission dissolved itself. 委员会解散了自己；或者作先行词的同位语，如：I went to the cinema myself. 或 I myself went to the cinema.
反身代词不能作主语，Wrong：Myself went to the cinema.

B， what the extent would be=程度会变成什么，
focused on whether Earth would grow warmer and to what extent=focused on whether Earth would grow warmer and focused on to what extent earth would grow，这里不再是结构的省略，而是根据语意做的省略

pile up 堆积，可以人堆积也可以物堆积，也可以被动式，如：She piled everything into her suitcase. 她把一应物品装进衣箱。； Work always piles up at the end of the year. 年底总是积压一大堆工作。；The clothes were piled high on the chair. 衣服在椅子上堆得高高的。
increase/slow/decrease/quicken 都用主动式，不用被动式，如：The price/rate/population/number increases. ；We need to increase productivity. 我们需要提高生产力。
be increased式形容词，如：The polymerization shrinkage value decreases when the molecular weight is increased。

B项不能证明良好判断力和决策做得好有因果关系

还是不太能理解E选项的解析，想请问如果我想用e的倒装方法去强调没有标尺的话，这句话要怎么说呢？

have developed可以省略成as sb have done

E是充分而不必要假设

Yet high rates of straying can be problematic because misdirected fish may interbreed with the existing stock to such a degree that any local adaptations that are present become diluted
high rates-> adaptation diluted
choice c如果取非，salmonid do not benefit from local adaptation, 就削弱了结论

直接细节：The numerical effect is obvious: there are fewer salmon in degraded regions than in pristine ones

直接细节题：Low levels of straying are crucial, since the process provides a source of novel genes and a mechanism by which a location can be repopulates should the fish there disappear.

however, habitat loss also has the potential to reduce genetic diversity

there was a rapid movement是产生similarity的原因，而不是rapid movement是产生similarity的原因

argument指的是ketcham的观点。本文都在讨论K的观点，而非美国政党领袖对于party的意见本身，因此不是theory about early history.

E中There are no major crops other than rice for which domestic production and domestic demand are currently in balance in Teruvia.，除了rice其他的农作物都没有达到供需平衡。---这句话的意思和我们通常设想的答案（这里的人以rice为主食，其他农作物不能取代它。这个作为这里的assumption很合理）这样的假设有很大的出入。其他农作物没有像目前rice一样达到供需平衡（可能是供大于需，也可能是需大于供），如果是前者还说的通，后者就完全不行了。这种带有可能性的选项排除为好

题目也没看清楚。脑子里想的都是which one must be true...

醉了。。。。

have/gain/lose the capability/ability of doing sth，拥有做某事的能力
B=turtles can endure long fasts, (because turtles) have their ability to survive ,不需要说have their ability，拥有的能力肯定都是自己的能力。
