标题: [求助]两道prep语法，谢谢

25. Ozone reaches high concentrations twelve miles above Earth, where it has long appeared that it was immune from human influence; we have now realized, though, that emissions of industrial chlorofluorocarbons deplete the ozone layer.

A) has long appeared that it was immune from

B) has long appeared to have been immune from

C) has long appeared as being immune to

D) had long appeared immune to

E) had long appeared that it was immune to

答案是D，似乎是最好的答案鸟。。。但想请教主语用的明明是一般过去时，为什么从句可以用过去完成时呢？

另外immune from和immune to有什么区别，怎么选择呢？谢谢！

39. Taste buds are onion-shaped structures with between 50 and 100 taste cells, each of them has fingerlike projections poking through the opening located at the top of the taste bud called the taste pore.

A. them has fingerlike projections poking through the opening located at the top of the taste bud called the taste pore

B. them that have fingerlike projections that poke through an opening located at the top of the taste bud, which they call the taste pore

C. which has fingerlike projections poking through the opening, called the taste pore, located at the top of taste bud

D. which having fingerlike projections that poke through an opening, which is called the taste pore, located at the top of the taste bud

E. which have fingerlike projections that are poking through an opening located at the top of the taste bud called the taste pore

答案是C，想请教为什么called和located之间可以不用连词呢？谢谢咯~~

webster里的解释：
用immune from的情况：
1，free,exempt; 例：immune from further taxation
2, marked by protection 例：some criminal leaders are immune from arrest
用immune to的情况：
1，not suspectible or responsive 例：immune to all pleas
2, especially-having a high degree of resistance to a disease 例：immune to diphtheria

楼主同学要好好学习啊！

我明白鸟。关键还是理解意思吧。taste pore我们暂且叫他“气孔” 他是=那个opening 的而located at the top of taste bud的那种东西是那种fingerlike projections
如果用and 就改造人类的舌头啦：P

哦，有点茅厕顿开呐,咔咔~~

偶现在比较明白鸟，不过有一点点不同意楼上dd的意见，那个called the taste pore是修饰opening没错，算是后置的定语吧，但是后面的located at the top of the taste bud其实是修饰那个taste cells，不过中间隔了一个which定语，和which定语中一个成分的定语。。。哇塞，应该是酱紫吧？！dd再帮偶看看！！

这题也太难鸟，偶这木头脑袋。。。

（倒装）谢谢小雷锋同学~~撒花~~

不愧是二位NN，讲的话偶们凡人都不懂

called the taste pore是修饰opening没错，算是后置的定语吧，但是后面的located at the top of the taste bud其实是修饰那个taste cells

二位NN这么讲，我能理解。

但是不会有歧义吗？ETS不是最怕有歧义了吗？

还是有疑惑， C中那个located at the top of taste bud到底是修饰哪个呢？

我个人觉得是修饰opening的

而called是做插入语

nn帮忙啊..
