Like the planets, the stars are in motion, some of them at tremendous speeds, but they are so far away from Earth that their apparent positions in the sky do not change enough for their movement to be observed during a single human lifetime.

1.具体内容上，at tremendous speed本身就是描述in motion的状况的，先写in motion 再描述如何运动更符合逻辑... 【Stars move at a fast speed】这样，而不是【Stars ,at a fast speed,move.不合理！】 2.主要内容是说stars，A中间被插入语just as the planets are打断了（本来已经有了一个插入语打断了主谓stars与 are in motion，不好），而后面又是继续讲star。 感觉B更连贯，前面简洁三个词表明比较，后面全部讲stars.

比较名词用like比as好。as+n.表示作为...，不表示像

the stars are in motion. 后面的some of them当中的them究竟是指代planets还是stars。 但是后面没有什么问题

1. yet 后面没跟句子 3. although 后边也没 verb 4. as 比较了两个名词 5. which错误指代了planet

like比较两个 名词：like A，B……，like后面不能接句子 As后面要接句子，不能比较两个名词 注意这里的like不是表举例，而是表比较

like the planet 比其他用as的好 in motion后面的at tremendous speed是用来修饰 in motion的 所以在这里：some of them at tremendous speeds 的位子正确 but they are... 又继续说star

A: The stars, some of them at tremendous speeds... Here, the STARS themselves seem to be at tremendous speeds. Not the intended meaning: a star can't be AT A SPEED. B: The stars are IN MOTION, some of them AT TREMENDOUS SPEEDS. Here, the stars clearly are IN MOTION AT TREMENDOUS SPEEDS. This is the intended meaning: at tremendous

不同类比较用as，排除AD，C选项although和yet用法存疑，E选项which指代存疑。

Although it may seem that the pronoun “they” is ambiguous and could refer to either the “planets” or the “stars,” the reference is actually clear because the subject of this sentence is “stars” and the whole sentence is about stars. Planets are just a kind of “throw-away” comparison here.

比较两个n，不能用as，只能用like。as如果跟n，是表示作为...，而不是表示比较 2. 如果要用于比较，as 必须接从句 所以b比d好 ace均有语法错误 所以不选
