【答案与解析】

1. A。该题测试疑问副词的用法，用科学推理法。从下句“有些以某种方式传播，有些以另外的一种方式传播”足能推测到该句的意思是“这些疾病如何传播”.

2. C。该题测试代词的用法。从句子的意思“一种……，另一种……”就能确定要选表示“另一”意思的代词，这样就可以排除首尾两个选项;the other指仅有两种传播方式，这显然与实际不符，也要被排除。

3. C。“从一个人传给另一个人”要用连词词组from…to… 来表示。

4. B。当你患了感冒时，与别人呆在一起，就有可能把感冒病毒传给别人，因此，in, with, among 都不能被选。

5. A。上面几句谈的都是感冒问题，本句应该是对“感冒”这一疾病的总结。

6. D。“细菌能以许多方式从一个人传给另一个人”属客观事实，因此要用一般现在时。

7. C。疾病不会自己传播，需要借助昆虫、苍蝇、蚊子等才能传播，因此，疾病作主语时要用被动语态。

8. A。动物传染给人类疾病，只是有可能性，不是“一定”被传染，更不是人类“需要”被传染，因此，只能选表示有某种可能性的情态动词can。

9. D。这是一道常识题。众所周知，SARS是由果子狸这种动物传染的。

10. D。这也是一道常识题。喝了患有疯牛病的牛产的奶是“致命的”，而不是“有趣的”，更不是“重要的”和“必要的”。
