conclude to 到达

OG关于D的解释：This comparison is faulty: The loss is not being considered in the context of total industry revenues but in the context of total sales of programs.
即，D选项比较的是全部盗版，而不是这个项目的盗版
且私以为比较后较小，或者占比较小，都不代表这个值本身小

ABD illogically compare beavers or the beaver populations to the eighteenth century.

C. The coordinating conjunction and introduces unnecessary words, as does the awkward phrase as compared to what it would be with . . . . The preposition with is incorrect.

A. Correct. Although not the most graceful sentence, this version correctly compares the rate at which birds huddled in groups burn energy with the rate at which they would burn energy as isolated birds

D. The participial finding has no agent in this version of the sentence. The preposition with makes the sentence wordy and nonsensical, as it is not clear what is being connected with the artifacts.

“独立主格结构”在句中的功能类似于一个带有自己主语的状语从句。

If by far is intended to modify is better known . . . it should be placed after known, or set off by commas, to prevent far from seeming to go with better. If by far is intended to modify better, this is incorrect usage.

只要有点看不懂的…必错。这螃蟹和藤…这词汇让我撞墙= =

如果x＝0呢？ 这样（1）选项就有0和1两种可能了 对吗？

只看题目的话，是类比推理。但实际的答案并不是...- -

这道题目写错了哦

MARK. 选了E.
注意rise higher赘余；和比较对象不对等，独立主格一定不能乱用啊啊啊

D选项看不出问题在哪里怎么办。。。

D选项中，in full view of ground- and space-based telescopes作为状语，侧重强调的是一种状态，而事实上应该是事件/动作本身provide new insight, 而且后面forcing不对，因此不选。不知道这样理解是否正确。

定从跟状从的修饰区分
