CD差异：robe长袍，C从句意思没问题的，但是主语是robe that they used to dress，像一个工具；而D中是robe with which they dressed, 衣服之间的装饰的感觉

逗号后面的句子是倒装

主谓单复数一致排除了AB，ce中either or平行不一致

A主语重复，B选项主谓不一致，C对，D excited句子对后面句子是修饰关系不是并列关系，E 主语重复

结论是 the PZ 1000 is one of the safest cars available today. PZ1000是当今最安全的车 不是说是同class里面最安全的车 我自动脑补了结论是它是同类型里面最安全的车

....把discourage当成encourage了...

D和E都是在说两个时间段的区别，为什么D不对呢？因为冬季气温太低，幼崽容易冻死，所以voles聚在一起生活，感觉可以解释问题啊。是因为D选项里没有提到young prairie voles这个关键词吗？求解答，谢谢老师~

The earliest date when people used tools，when可以拆解成介词+which
The earliest date that people used tools，that只能替换人或物，这里缺的是时间状语，用when或in which

it is X that does Y
this construction should be used only when there is a compelling reason to emphasize the X, but here is no good reason to use it.

A; "displaying grasses" appears illogically to modify either "5 million acres" or " that gives mouth sores to cattle". In this structure, it could only potentially modify these two things, rather than "a herbaceous plant"

B; That....modifies "herbaceous plant' instead of "milky sap",because that "with milky sap" could be omitted.

关注结论，B国要进口很多谷物。D。进口肉类更划算，就算随着经济发展人均吃肉增长，我们可以多进口肉嘛，没必要进口谷物。

assume 假设，假设就是加强。其他生厂商不会因为杂志和竞争对手联名了就觉得杂志不好了。言外之意，我不在意，不影响我继续找你杂志打广告，也就不会影响杂志收入。本来在CD之间犹豫，但是D是个额外的好处，联名了之后有新的客户被吸引来了，额外的好处

with the goal of doing----correct
with the goal to do---incorrect
reduce the number of guests----correct
reduce the guests----incorrect

the first/second people to do sth，第一个做某事的人，to do表示某人具有的性质
it's adj of sb to do sth，

没看懂最后一个选项，智商捉急。主要是因为看到第一行的扫描仪和打印机，后边的句子自动脑补所有的scanner都是打印机了，所以觉得E很奇怪，点大小跟打印有啥关系。
结论：用了现在的scanner印不出来小点印在新钞票上，就可以杜绝假钞。
E。现存的扫描仪在未来很久都不能缩小现在最小的点。也就是说无法做到和真钱一样，所以plan就有有用。

在有逻辑主语的情况下，用动词，prohibit sb from doing sth，禁止某人沾手某事，禁止某人触碰做某事的这个过程，

在没有逻辑主语的情况下，用动名词，prohibit the action noun of sth，强调要禁止的是某事所产生结果 。如：
prohinit smoking in public places 禁止在公共场合吸烟，禁止的是吸烟后烟雾对其他人的影响
a law prohibiting the sale of alcohol 禁止售酒，禁止的是售酒后对那些卖酒的人产生不良的影响
an agreement prohibiting disclosure of its methods禁止技术泄露，禁止的是技术泄露后对持有该技术的公司产生的不良影响
W：an agreement prohibiting its methods to be disclosed
W：an agreement prohibiting its methods from being disclosed

2.5起码大于1+1

牛逼，根本没想到这一步
