需要和in reducing the risk of heart disease and stroke平行

同求helr大神的表格

请问老师像B选项这样though without taste and odor 连词加介词短语的形式是可以的吗？连词不是只能加句子或者伴随状语吗？

同时性？！

上一个帖子po错位置了，又删不掉。。。
这道题E选项的错误是，the last day that they are scheduled to collect' means, literally, that the workers collect days。。。collect days? .... that doesn't make a lot of sense.
RON 的忠告：do not read the sentences very literally, like a robot , instead, use 'common sense' to justify improper, inaccurate, or ambiguous wording.

我是直接认为while作为连词，接完整的句子，D直接杀

注意这里面的几个点，为什么加the？derive为何不用被动？（和originate道理一样）derive为何不用一般过去时？因为是客观事实，比如下面的例句？medieval physicians were the first to discover that blood circulates through the human body

the meanings are different. if you just say "northern and southern indian alphabets", then it seems like you're just talking about some northern and some southern indian alphabets - i.e., nothing necessarily complete or exhaustive.
if you use "the", then you're talking about THE alphabets, i.e., all of them.

动词为什么一定要是be,不是is呢？

还原一下as they are the current one?

我觉得almost expected to double和expected almost to double也是一个很好的split。“差不多被期望增加一倍”和“被期望差不多增加一倍”是两个完全不同的概念。

不定式和xx区别？

我也觉得E选项的leave behind歧义很大。。应该是把矛头留在动物体内的意思，如果说留在猎人自己身边感觉很牵强。

c，strains种类

While data suggest that population densities of nectar-feedingbats are also low in tropical areas of southern Mexico, where bats are the exclusive pollinators of many species of columnar cacti－－southern Mexico的蝙蝠授粉是唯一的，蝙蝠又是夜间授粉。相反的Sonoran Desert的就不是蝙蝠唯一授粉，也就是说有时候由日间授粉者进行授粉。所以是E

and 连接的两个动词 date from 和 were fashioned时态不一致的感觉啊？？？
