A：The main verb is "denounce." From there we have two things happening "saying government is doing too much...WHILE...supporting many specific programs." Saying/Supporting is parallel.
B：As soon as we say "they say" again, we've started a new independent clause. That's not okay. Also "they denounce...but supporting" doesn't work
C：they denounce……，they say……缺少连词. Also "at the same time" needs to come BEFORE "they support." If they place it afterwords, it sounds like the people are going to be supporting TWO things "at the same time."
D："While" starts us off in something dependent, then both "saying" and "supporting" are opening up participial phrases. while引导从句，缺主句
E：while they……，supporting at the same time,缺主句。同C,at the same time位置放置的不好，这样会有supporting TWO things at the same time 的歧义。

相关→因果

B:that would control限定修饰a new company
A: 表目的用for doing 还是to do，后者更优；另外，forming现在分词作状语表随之而来的结果，后面又跟个目的，是否合乎逻辑，心里打个问号。

相关→因果推理

因果推理
P: The virus will infect bilby, an endangered native marsupial.
C: Using the virus will increase the threat of native wildlife.

C选项说明在用virus之前bilby就已经被兔子威胁到了，用virus会同时感染bilby和减少兔子数量，正负作用都有，不能说一定增加威胁

果因推理：
P: the number of female adults sea turtles coming back to lay eggs has increased since five years ago.
C: the chemical spill five years ago wouldn't decrease the population of sea turtles.

B选项说海龟10岁才回来产卵，所以这五年过来产卵的海龟至少都是chemical spill之前一年出生的海龟，提供了它因：这五年回来产卵的海龟数量增加是因为chemical spill前五年出生的海龟数量增加，而不是因为chemical spill对海龟数量没影响

比较的是level，另外A中than 后面跟were向前找不到对应平行结构。

主谓一致，排除DE；
时态：C选项现在进行时的被动语态不好，A一般现在时更优；
代词：B-programming them指代不清；
结构：C-but和instead语义重复
语义：比较A和B,本句想要比较的到底是什么呢？are programmed to work vs. learn to work.

B其实偷换了概念，原文说的是牙齿上的heavy enamel，B直接替换成了micro-wear patterns

with plenty of bumps 里的with有“有，用，和”的意思，不如have来的清楚。although应该是可以省略主语和be动词的（如果主语和主句主语一致）。

E 我觉得是any indication太过于绝对了…… 不过这个D还真的蛮难看出来orz

they不能指代前面三个名词，因为前面三个名词不能主动预测（应该是被预测），所以这里的they没有指代对象

between 2 and 100 是 不包括 n = 2 吗？

A:Starfish是个复数，it quickly replaces it只能指手臂能恢复手臂。另外by the animal overcompensating没有逻辑主语
B:独立主格做状语修饰前方动词replaced，动物过度补偿&动物长出extra one or two。正确
C:by the animal overcompensating没有逻辑主语同A
D:If they lose one arm they are quickly replaced意思是如果Starfish掉了胳膊那么Starfish就会被替代。掉了个胳膊不用整个把Starfish替代了吧。LOL
E: E真的挺模糊的，我去英文网站上逛了一圈
In (E), “growing” has been turned into a modifier (“sometimes with the animal overcompensating, growing an extra arm or two”), and I’m not sure that it’s wrong, but it seems a little bit odd to me: when do you ever see an "-ing" participle modifying another "-ing" participle? Meaning-wise, I suppose you could argue that “growing” tells us extra information about when happens when the animal is “overcompensating”, but I think it makes more sense to keep the two actions (“growing” and “overcompensating”) parallel.

主语和宾语是同一个人时，使用反身代词，主语：employees，谓语：pick 宾语： those most important to them（对他们来说最重要的benefits，to them起修饰作用）,因此不需要使用反身代词，排除b/c/e—>d选项 are offering and let不平行—>选择a

not...but...平行触发语，必须严格对应

A: and dated at 34 million years old是定语从句的一部分修饰前方主语fossils, 与后面的made it the earliest known mammal没有修饰关系。
其次，如毕老师所说。and前面的逗号不该加，只有三者平行或者两个完整的句子的时候and前面才加逗号
B: 主谓不一致，主语fossils谓语has。they没有指代对象
C: 主谓不一致
D：对，making the sloth...作为伴随修饰前方动作have been dated.
是因为确定年纪很老才成为最早的哺乳动物
E：Which前面没有逗号错误，was主谓不一致。逗号不可以隔开主干成分主语和谓语

B的介词短语既可能修饰名词water treatment and conservation projects也可能修饰动词propose，故存在歧义，而D定语从句只能修饰名词water treatment and conservation projects，故不存在歧义，更优。

A: snow三兄弟超过amount不对，然后capable of being绝对语法错误（能够被怎么怎么样？被怎么怎么样不需要门槛）
B: snow三兄弟超过amount不对
C: amount of snow三兄弟超过amount，对
D：snow三兄弟超过amount不对
E: region 超过amount 不对
