A 解析:此处为委婉提供建议,could表“可以”,语气客气,符合对话场景;must语气太强硬,need需加to。3. A 解析:“每天锻炼保持健康”是义务性建议,should表“应该”,符合逻辑。2. 反身代词(oneself/oneselves)【语法精讲】构成规则:由人称代词加后缀-self(单数)/selves(复数)构成,需与主语在人称、数上保持一致。单数:myself(我自己)、yourself(你自己)、himself(他自己)、herself(她自己)、itself(它自己)复数:ourselves(我们自己)、yourselves(你们自己)、themselves(他们/她们/它们自己)核心用法:作宾语:动作承受者与主语为同一人常见搭配:hurt oneself、teach oneself、by oneself。作同位语:加强语气,表“亲自”,可置于主语后或句末。作表语:用于“be动词+反身代词”结构,表主语状态。课本例句:I hurt myself when I fell off my bike.(我从自行车上摔下来伤了自己。)—— 反身代词作宾语。拓展例句:He taught himself French last year.(他去年自学了法语。)—— 作宾语,搭配teach oneself。I did the homework myself.(我亲自完成了作业。)—— 作同位语,加强语气。She isn't feeling herself today.(她今天感觉不太舒服。)—— 作表语,表身体状态。They enjoyed themselves at the party.(他们在派对上玩得很开心。)—— 固定搭配enjoy oneself。易错点警示:错误 :Myself finished the work.(反身代词不能单独作主语)正确 :I finished the work myself.错误 :He hurt him.(动作承受者与主语一致,需用反身代词)正确 :He hurt himself.【针对性练习题】( )1.
