A. very good B. much better C. rather bad D. even worse
【分析】答案選D。根據(jù)句中的than可知，空格處應(yīng)填一個比較級，故可排除A和C；再根據(jù)句中Something must be done to stop it（必須采取措施阻止它）可知，應(yīng)選D而不選B。
【考例2】Tian’anmen Square is one of ________ squares in the world. (北京中考題)
A. large B. larger C. largest D. the largest
【分析】答案選D。根據(jù)句中的one of…in the world可知，說話者是把“天安門”與世界上所有的廣場來比，故要用最高級（同時要注意在最高級前加定冠詞）。
【考例3】—Junk food is bad for our health.
—Yes, the ________ you eat, the healthier you will be. (北京朝陽區(qū)中考題)
A. little B. few C. less D. more
【分析】答案選C。此題考查“the+比較級，the+比較級”結(jié)構(gòu)。句意為：吃得越少，健康就越好。
考點(diǎn)10 考查as…as結(jié)構(gòu)的用法
as…as結(jié)構(gòu)的意思是“與……一樣”，在該結(jié)構(gòu)的兩個as之間總是用形容詞或副詞的原級，不能用比較級或最高級。如：
He’s as old as she [her]. 他年紀(jì)跟她一樣大。
該結(jié)構(gòu)若用于否定句，則可將第一個as改為so，即說成not as…as或not so…as，但是，在肯定句中是絕不可能用so…as的。如：
He doesn’t study as [so] hard as his brother. 他學(xué)習(xí)不如他弟弟努力。
修飾as…as結(jié)構(gòu)的常見詞語有nearly, almost, just, exactly, half, quite, twice, three times等，請注意這些修飾語都只能放在as…as 結(jié)構(gòu)之前 (而不能置于其中或其后。如：
I earn half as much as you do. 我只賺你的一半錢。
This rope is twice as long as that one. 這根繩子比那根長一倍。
【考例1】We don’t have much homework now and our school bags are ________ they used to be. (遼寧錦州中考題)
A. as heavy as B. not as heavy as C. as heavily as D. not as heavily as
【分析】答案選B。as…as的意思是“與……一樣”，not as…as的意思是“不如……”，根據(jù)前文說的“我們的作業(yè)不多”可推知，“我們的書包不如原來重”，故可排除A和C；又因?yàn)榭崭裉幨怯糜谶B系動詞are之后作表語，所以要選形容詞heavy，而不是副詞heavily。
【考例2】—I think English is ________ math. (www.hz123456.com)
—Yes, I think so. (湖北恩施中考題)
A. much important than B. so important as
C. as important as D. as more important as
【分析】答案選C。首先應(yīng)排除B和D，因?yàn)樗鼈兊慕Y(jié)構(gòu)有問題：as…as只能在否定句中才可改為so…as，所以B不能選；又因?yàn)?/SPAN>as…as之間只能接形容詞或副詞的原級，故D也不能選；至于A，由于其中用了than，但句子中卻沒有比較級，所以也不能選。
