1.重點是弄清 have sap / displace / render 三個的邏輯關係
2. SVO, N ving OK
3 .SVO, N that OK

NOTE: In A, B, and C, the phrases "so that" and "in that" would modify some kind of action, as in "He went to the store so that he could find Amy" or "It was a bad move in that it resulted in him getting dumped by Amy." We don't have an action we want to modify here (i.e., the only verb we have in the first half of the sentence is "are", and we're probably not modifying that).

D one parasite can only have one lifecycle

because=in that，连词性质
instead of是介词，要么做定语修饰elbow，要么做状语修饰attach，怎么看都不对
还是rather than好啊，连词就没那么多毛病了，想跟谁并列跟谁并列，rather than前后直接两个状语并列，多好

XX of sth表示XX从属于sth，A选项的意思是，特权从属于开药这件事，例如，legs of a table，语义不对，应该直接是开药特权。一定要注意，介词有自己的含义，不能翻译成中文去感受

介词表特征且介词自己是有含义的（for：为了），同位语才是对先行词具有解释力

from when，from是介词，后面加名词/动名词，不能加when，when做定语只能跟在要修饰的时间词后面（定语从句可以跳跃修饰），否则就是时间状语。

一个自然现象不能是suggestion，用phenomenon可以。
A do B， doing C，如果觉得是A do B 这整个事情在doing C，那其实就是A 在do C。

没有给tribes的范围，one another表示另一个，each other表示互相

now with是survive动作的伴随，数字无法伴随动作，因此直接排除DE；分号前后可以隔开完整句子

看and后面的句子成分的组成，工整地平行到and前即为并列的部分

examples:
Most Americans consider Beverly Hills, a ritzy suburb to the north of Los Angeles, to be a desirable place to live.

所谓看作和认为的区别不敢苟同。
-RON
(1)Consider X to be Y
(2)Consider X Y
the first two have exactly the same meaning; you'd use the first only when the extra words 'to be' are justified, either because they resolve some sort of ambiguity or because there's just A LOT of stuff between 'X' and 'Y'.

看清句意想逻辑

D：while ponding 逻辑主语
E：代词指代

E选项：代词the ones的指代对象为前面出现过的名词some places中的某些

B选项：在语法上，同一个代词的指代对象应相同。但在本选项中，them应指代benefits，而themselves应指代employees。
themselves--wordy, unclear; 'to themselves' modifies pick or most important of them;

重点B
