逻辑问题 using发出者只能是goverment~

although 后面要加完整的句子！

不能用equally...as
比较的是driver will do 和driver current do, so we should use dievers will be as likely as they are now

没有发现uncovering是个v！！！

improve access to resources 做得时候一直没懂for famer to是什么结构，改错时才恍然大悟

"trucks themselves" doesn't make sense.
you don't use "x itself" unless you are trying to emphasize some element of the inherent nature of x (as opposed to something associated with x, or with some part of x).
example: pet accessories are becoming more and more popular, even though pets themselves have maintained constant popularity.

#1choice (b) conveys this idea accurately, with the phrase "twice that number". see, "that number" must refer to an actual number cited in the sentence
choice (d) DOES NOT convey this idea. that choice says "twice AS MANY trucks", which means "twice as many trucks as were produced in 1914".
the problem is that the sentence doesn't tell us how many trucks were produced in 1914

* the sentence openers starting with "with" are incorrect. to work properly, they'd have to be followed by a subject that's actually "with" those things.

* "the fact of X doing Y" is universally incorrect.
this kills (a).

注意：并不是fossils使sloth成为最早的哺乳动物，而是fossils被定位在...年前使sloth成为最早的哺乳动物。所以要用comma+ing。

what's probably an easier way to eliminate the same choice is to realize that you can't block off a modifier with a comma on only one side. modifiers should be blocked off either with commas on both sides (nonessential modifiers) or with commas on neither side (essential modifiers).
in that choice, "found in Puerto Rico in 1991" is blocked off with a comma on the right, but not on the left. bad news.

The sentence starts is Caribou " are", hence all references to "it" at the end, should be considered incorrect.-> Strike off A,D and E. The correct pronoun reference would be "they"

the OA makes sense if the company was in the midst of closing the stores (or had just begun to close them) at the time of the announcement.
if the company had not yet begun to close the stores, then you would use "would": the company announced that it would close / would be closing 1/4 of its stores...

我也觉得是类比。。

比较的题型：1）比两样东西（名词），2）比两个动作（动词）。
这里比较的是两个动作，所以，有一个省略用法 [sub+verb]+modifier，只保留modifier，选C。
如果是比较两个东西, 比如circulation in.... is lower than that in ....，就应该是D。

while在这里作什么？连词？连接两个句子？可是while不是有转折的意思吗？这里应该是两个并列的成分啊

第四遍错。。。呵呵哒啦
我真的不懂B with milky sap是个插入语ok 忽略不看。 后面的that修饰的是谁？难道不可以是euraisa吗 而实际应指代a herbaceous plant 所以不会显得指代有误吗？ 对c选项，我觉得后面的displacing grasses是和having milky sap并列 而不是和gives mouth sores并列，这么理解为什么不对呢？
