1. The number of plant and animal species that (humans are known to have forced to extinction) in the last half millernnium is over 800.

A. humans are known to have forced to extinction
B. humans are known as having forced to become extinct
C. humans are known for forcing to become extinct
D. are known that humans forced to become extinct
E. are known as having been forced to extinction by humans

I chose E. The given correct answer is A.   可是总觉得 E 比A 念着顺溜?

2. The success of the program to eradicate smallpox has stimulated experts to pursue (what they had not perviously considered possible --- better control, if not eradication, of the other infections such as ) measles and yaws.

A. what they had not previously considered possible --- better control, if not eradication, of the other infections such as

B. what they had not previously considered a possibility --- better control, if not eradication, of such infections like

C. something they had not previously considered possible --- better control, if not eradication, of such infections as

D. something not considered a previous possibility --- better control, if not eradication, of such infections as

E. the possibility of what they had not previously considered -- better control and possibly eradication of infections like

I chose A. The given correct answer is C.

I think the "what" usage in A is better than "something" in C. Besides, isn't it necessary to add "that" after something in C?   However, "of such infections as" in C is better than "of the other infections such as" in A. Hard to decide which is better overall.

1. two reasons why A is the right answer:

1) idiomatic expression: be knowned to do sth.

2) active tense is almost always better than passive tense.

2. I think C is better than A for one reason: when we say"...other infection, such as A and B", there should be a comma before "such as."

I think there is nothing wrong with the first part of the sentence in A. And I believe "that" can be omitted in B.

完蛋！我两道题都和楼主选的一样的。咋整啊

首先第一题A有问题，that在从句是什么？宾语，定于从句要省略that!第二题what用的没什么不对，而且后面的other 表达了另外那些举例和前面的病同样是infection，很清楚。。。哪位高人解释一下啊
