1.句意：他们希望它能保护他们免受可怕的空气污染。A. in在…之中；B. from（表示分离）与…分离；C. for为了；D. at（表示位置）在；结合语境可知，用介词from，protect …from 保护，免于。故选B。

2.句意：脏空气看起来像雾和烟的混合物。本题考查定语从句。先行词air是物，因此用that引导。故选A。

3.句意：很差的空气对人们的健康有害，尤其是对儿童和老人。A. lucky幸运的；B. especial特别的，突出的；C. especially尤其地；D. luckily幸运地。A/B两项是形容词，后面直接修饰名词，排除A/B；结合语境“很差的空气对人们的健康有害，______ 是对儿童和老人。” 可知，应该是尤其。故选C。

4.句意：他们很容易生病，医院里挤满了人。A. schools学校；B. gardens 花园；C. zoos动物园；D. hospitals医院。由句子They fell ill easily他们很容易生病。可知，生病以后得去医院看病，所以是医院里挤满了人。故选D。

5.句意：所以有必要阻止人们做许多坏事来破坏环境。It's necessary to do sth. 固定句型。做某事是必要的。故选C。

8.句意：来自于北京第4中学的三名学生写了一篇报告建议人们如何去保护环境。由下文的句子They suggested ___9___ people should plant more trees and set off fewer fireworks for celebration.可知，时态为一般过去时，因此本题的时态也为一般过去时，说明报告是过去写的，因此用过去时。故选A。

9.句意：他们建议人们应当多种树，在庆祝的时候尽量的少放烟花。A. which哪一个；B. where哪里；C. that用于某些动词、形容词和名词后，引出各种从句；D. who谁；结合语境可知，本题是由that引导的宾语从句。故选C。

10.句意：我们希望更多的人加入我们的行列。in为介词，因此后面用动词的-ing形式。故选D。
