因缺少录音内容，无法给出确定答案
解析
本题为听力理解题，需根据所听录音内容，辨别各小题选项单词的发音差异，选出对应选项。但因缺少录音素材，无法确定具体答案。
()1.There are plastic bags at the snack bar.
A.a lot
B.a lot of
C.much
A.a lot
B.a lot of
C.much
答案
B
解析
首先判断空格后是可数名词复数plastic bags。A选项a lot是副词短语，不能修饰名词；C选项much仅可修饰不可数名词；B选项a lot of可修饰可数名词复数或不可数名词，符合要求，故选B。
()2.If people want to save water, it is a good choice(选择)to it.
A.use
B.waste
C.reuse
A.use
B.waste
C.reuse
答案
C
解析
题意为“如果人们想要节约用水，______是一个好选择”。分析选项：A.use（使用）未体现节水；B.waste（浪费）与节水要求相悖；C.reuse（重复使用）是节约用水的有效方式，符合题意。
()3.Is watching TV bad for children's eyes?
A.too many
B.too much
C.much too
A.too many
B.too much
C.much too
答案
B
解析
1. 区分选项用法：too many后接可数名词复数；too much后接不可数名词；much too后接形容词或副词。2. 句中TV为不可数概念，因此选too much。
()4.Planting many trees can help the air clean.
A.keeping
B.keep
C.keeps
A.keeping
B.keep
C.keeps
答案
B
解析
本题考查固定搭配“help do sth.”（帮助做某事），help后接动词原形。选项中只有keep是动词原形，符合要求，故选B。
()5. too much chocolate is bad for our teeth.
A.Eating
B.Eat
C.To eat
A.Eating
B.Eat
C.To eat
答案
A
解析
英语中动词原形不能直接作句子主语。动名词（动词加ing）可作主语表示经常性行为，不定式作主语常表具体某次动作。本句描述的是经常性行为，因此选Eating对应的选项A。
