Q30:

In 2000, a mere two dozen products accounted for half the increase in spending on prescription drugs, a phenomenon that is explained not just because of more expensive drugs but by the fact that doctors are writing many more prescriptions for higher-cost drugs.

1. a phenomenon that is explained not just because of more expensive drugs but by the fact that doctors are writing
     
2. a phenomenon that is explained not just by the fact that drugs are becoming more expensive but also by the fact that doctors are writing
     
3. a phenomenon occurring not just because of drugs that are becoming more expensive but because of doctors having also written
     
4. which occurred not just because drugs are becoming more expensive but doctors are also writing
     
5. which occurred not just because of more expensive drugs but because doctors have also written

为什么C不对呢,

B将原来的因果去掉了

而且如果是C的话,就是not but 也不用操心not just but also存不存在了.

另外AB的THAT IS 也不大好啊

盼NN指点

 explained because...错误的句型

有明确时间 in 2000，还是用定于从句修饰比较好

还是不大懂,讨论中也没怎么讨论过

还请指点

感谢!!!!!!

C的逻辑意思不通

because of +名词

因为药物所以现象是说不通的，因为医生所以现象也是说不通的。

应该用because +句子来描述。

A不平行

B是唯一较好的

但是B里面也有不好的地方，ETS一定是喜欢not only。。。but also的，但是B没有满足。

got it

thanks a lot
