Ozone, a special form of oxygen that screens out harmful ultraviolet rays, 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. 由于前面没有过去时态，所以这里也没有必要用过去完成时，所以在A B C中选

(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

望指教啊

对于第一个，as varied as列举的是前面的countries而不是主语green taxes。
第二个的话我感觉跟分号后面的we have realized有关，虽然是两个独立的分句，但是后面的分句是说我们已经意识到，所以前面用过去完成时说当时还在认为是免疫的吧。
第三个risk of doing是个比较固定的用法，然后one chance in a million chances中应该省略后面一个chances吧。

Socalled green taxes, which exact a price for the use of polluting or nonrenewable fuels, are having a positive effect on the environment and natural resource base of countries as varied as China, the Netherlands, and Hungary.A

(A) as varied as

(B) as varied as are

(C) as varied as those of

(D) that are as varied as

(E) that are varied as are
在Manhattan论坛学到的， as varied as 表示包括，表示举例，这句话翻译出来就是， 所谓的环保税，（。。。），现在对环境和国家，比如/包括 中国，荷兰，匈牙利 的 自然资源 有着积极地影响。
B 中的are 没有必要补出来，the countries themselves aren't "varied"， it would be incorrect to say that "the countries are varied", so it's not correct to use the verb "are
D中的 that 引导限定性定语从句，  the wrong answer (D) seems to imply that EACH country is somehow as 'varied' as EACH other country. That's not the intended meaning, which is that the SET of countries is varied
我觉得在这里应该把as varied as 看成固定搭配 ，再举几个例句

Known as transmissible spongiform encephalopathies, or TSEs, they arise spontaneously in species asvariedas sheep, cattle, mink, deer and people.
	如我们所知的传染性海绵状脑病(TSEs)，在不同物种如羊、牛、水貂、鹿和人中同时存在。

第二题，Immune from表示 豁免

Immune to 表示不受影响 而本题的意思是不受影响，E明显错，所以选D

第三题，固定搭配，risk。。。of  doing sth 所以选D
