我想问一下这里的比较： as be the case (with), 需要比较对象对等吗？但是后面的句子主语是 prescriptions 啊！
又发现了几句都是考 as be the case with 用来比较的，好像比较对象都是对等的。

Like any star of similar mass would do, once the Sun has exhausted the hydrogen in its core, it
expands into a red giant, eventually ejecting its outer envelope of gases to become a white dwarf.

自己再顶一下，看看有没有NN可以帮忙看看。
谢谢了。
在顶一下。看看有没有NN给点意见。
此题如果你认为后面几个例子是对等的，怎么会认为39题是不对等的呢？他们都是一样的啊。
如59题的主语是papaya，120题的主语是Sun。如果你是指with后面的部分，那与对等也没有关系啊。
这个用the case指代后面相同情况的用法，不需要比较对象对等。
而这个用法，记下来就行了，知道这么用是对的就行了。
比如39题的C用另外一种语序也是对的：As is the case with traditional pharmacies, on-line drugstores rely on prescriptions to be successful.你想强调哪一部分就把哪一部分用作主语。
As is the case with traditional pharmacies, prescriptions
are the cornerstone of a successful on-line drugstore, since it is primarily prescriptions that attract the customers, who then also buy other health-related items.
我的问题是：在未划线部分since引导的从句中it的用法。若是指代前文的drgustore，显然逻辑意思不通。应该是it做形式主语，向后指代that从句，是这样理解吧？此外，since引导的是原因状语从句，对前文进行解释说明的，对吗？
期待NN给我肯定答复！
Thanks!
刚看到一个好帖，放过来一并看。有关 as with和as be the case(with)

Good point. If the above is true, the correctly way to use “as with” here is: As with other pharmacies, online drugstores rely on prescriptions to have success.
2楼的朋友说的不错. case和prescriptions are the cornerstone of a successful online drugstore是并列关系, 所以用了case就不能as with.
再把P1-59/120正确答案带入原文，贴到一起。方便复习、理解。
59.A new genetically engineered papaya was produced
not by profit-motivated seed companies, as was the case with most genetically modified crops previously approved for commercial use,
but by
university and United States Department of Agriculture researchers who allowed growers to use it free of charge.
120.As would be the case with any star of similar mass, once the Sun exhausts the hydrogen in its core, it will expand into a red giant and eventually eject
its outer envelope of gases to become a white dwarf.
As is the case with traditional pharmacies, prescriptions
are the cornerstone of a successful on-line drugstore, since it is primarily prescriptions that attract the customers, who then also buy other health-related items.
我的问题是：在未划线部分since引导的从句中it的用法。若是指代前文的drgustore，显然逻辑意思不通。应该是it做形式主语，向后指代that从句，是这样理解吧？此外，since引导的是原因状语从句，对前文进行解释说明的，对吗？
since 后面的是强调句型
it is primarily prescriptions that attract the customers, who then also buy other health-related items.
primarily 是修饰 is 的，变为正常语态时可以去掉。
prescriptions attract the customers, who then also buy other health-related items.
请问A和D中rely on prescriptions to be successful这个表达方式对不对？
B中rely on prescriptions to have success这个表达方式对不对？
能否具体解释一下，预先谢谢！！！
那rely on prescriptions to be successful呢？
版主人在何方啊？这么晚还回帖，感激！！！
as be the case with sth.
就像是关于sth.的那种情况一样
查了longman，原来rely on sth. to do sth.是固定搭配。
