31、后接形容词、副词 ; too many 后接可数名词复数; too much 后接不可数名词, pollution 是一个不可数名词，故选 B。4.D 本题考查 at least 和 no+adj.(比较级)+than ，表达的含义是“至少它不比你买给我的（花）差。 ”5.B stand 作及物动词，意为 “忍耐，容忍”后接名词、代词或动名词作宾语。6.C 本题考查 make sb. do sth. 这一结构。7.B 动词（组）作主语，应用其动名词-ing 形式。8.B 本题主要考查 yet 在现在完成时态中的运用，yet 用于否定句和疑问句中，already用于肯定句中。9.B There
32、be+sth./sb. doing sth. 为固定句型，意为“有某人或某物正在 ”。10.A see+宾语+doing ，表示“看到某动作正在进行” 。.11.Where have you been?12.How did you go there?13.Have you ever been there before?14.Whom did you travel with?15.How long have you been away?.16.A see 看， throw 扔，drop 丢，clean 弄干净，根据题意此处选 A。17.D 本句的题意: 我能在三分钟内走到那儿。in three
33、minutes 表示 3 分钟内，故选D。18.C 本题考查 so that 句型,表示“如此以至于” 。本句题意: 但是有一天，这儿有那么多的垃圾，让我很不高兴。故选 C。19.B 本题考查系动词+ 形容词。根据题意可知: feel happy 感到高兴。20.A 本句分析句子结构，有一个介词短语 after I started to pick up litter 修饰 ten minutes来作时间的定语，指“捡了十分钟的垃圾后” 。所以选 A。21.C 由 four times a year 一年四次，表示频度，可看出此处时态用一般现在时。22.D 从全文来看，作者为了保护环境而去捡垃圾
34、，这件事不是让“我”感到累、难过、有趣，而是一种责任和成就感。所以此处选择 D 项。23.C any 在此处表示 “任一” ，本句含义是“如果垃圾中有任何能够回收再利用的，我都把它留下来” 。A、B 两项均修饰可数名词，而 litter 是不可数名词，D 项不符合题意。24.A until 后跟短暂性动词，表示 “直到才” ，从题意来看只有 A 项符合。25.B 根据题意“我只是做了一点事去帮助地球 ”。此处是用不定式短语来作补语。.（A）26.A 从第一段 We have changed our planet in many ways. 得知人类使地球改变了很多。27.B 文章中主要讲述了水
35、、空气和土壤三个方面的污染。28.A 本题考查了反意疑问句的答语。根据语法，C 、D 两项首先排除。B 项意为“是的，不严重。 ”根据全文及生活常识，污染已成为世界上最大的问题之一，因此 B 项排除。29.A 由第一段最后一句可知，我们的所作所为 more are not good for the earth。故选A。30.B 墨西哥城由于严重的空气污染已失去了往日的美丽，故 A 项排除。现在不是很少的农民使用农药，而是大部分，故 C 项排除。工厂、汽车等引起的是空气污染而不是土地污染，故 D 项排除。（B）31.F 文章第一段的结尾 Noise is a loud or unwanted s
36、ound. 已讲明了什么是噪音。本题陈述与原文不符，故为错误。32.F 从文中第四段首句可得知分贝是测量声音的单位。本题陈述的内容与原文不符，故为错误。33.F 从第三段 Doctors have found that these people have trouble in sleeping. 一句中可得到答案。34.T not all 部分否定，意为“并非所有的都” 。 这个问题在 And, to some people, rock musicis also a noise. 一句中得到答案。35.T 从阅读本文可得此答案。（C）36.Because they couldnt unders
