在时，行为动词do作谓语，主语he为第三人称单数形式，故其否定形式是在do前加doesn’t。5.Ckeepsb.+adj.“使某人保持(某种状态)”，故排除A、B两项；由句意“我每天吃水果、喝牛奶来保持身体健康”知选C。Ⅲ.1.gets2.playing3.help，(to)open4.do，do5.once6.hardly7.exercises8.more9.shopping10.isⅣ.1~5CDCAC6~10ACDCBⅤ.Onepossibleversion：Herearetheresultsofthesurveyofthestudents’activitiesinmyclass.Allthestudentsexerciseeveryday.Ninetypercentofthestudentseatfruitanddrinkmilkeveryday.Sevenpercentofthestudentseatjunkfoodthreetime
