一、语法讲解
(一)用于提建议的情态动词:should could
1. should(表“应该”,语气较强,侧重责任、建议、劝告)
肯定:主语+should+动词原形
例:You should study hard.(你应该努力学习。)
否定:主语+should not/shouldn't+动词原形
例:You shouldn't eat too much junk food.(你不应该吃太多垃圾食品。)
一般疑问:Should+主语+动词原形?
例:Should I help him?(我应该帮他吗?)
特殊疑问:疑问词+should+主语+动词原形?
例:What should I do now?(我现在该做什么?)
2. could(表“可以、不妨”,语气委婉、客气,侧重委婉建议,非过去式)
肯定:主语+could+动词原形
例:You could talk to your parents.(你可以和父母谈谈。)
否定:主语+could not/couldn't+动词原形
例:You couldn't copy others' homework.(你不可以抄别人作业。)
一般疑问:Could+主语+动词原形?(表委婉请求/建议)
例:Could I sit here?(我可以坐这儿吗?)
特殊疑问:疑问词+could+主语+动词原形?
例:How could I solve this problem?(我该怎么解决这个问题?)
3. should vs could 区别
should:建议更肯定、有“理应如此”的意味,语气偏强硬;
could:建议更委婉、试探性,给对方留选择空间,语气更温和。
4. 重点与易错点
回答“Could I/you...?”时:提问用could表示礼貌,但肯定回答用can,否定回答用can't或sorry等。例如:
— Could I use your pen? — Yes, you can. (不说 you could)
should 的其他含义:除提建议外,还可表示“义务”(学生应该努力学习)或“推测”(他应该到了)。
二、反身代词
1. 形式(人称对应)
第一人称:myself(我自己)、ourselves(我们自己)
第二人称:yourself(你自己)、yourselves(你们自己)
第三人称:himself(他自己)、herself(她自己)、itself(它自己)、themselves(他们/她们/它们自己)
2. 核心用法
作宾语:主语发出的动作作用于自身,例:He hurt himself.(他伤到了自己。)
作同位语:强调“亲自、本人”,例:I did it myself.(我亲自做的。)
固定搭配:by oneself(独自)、enjoy oneself(玩得开心)、help oneself to(随便吃/用)、teach oneself(自学)
3. 易错点
指代一致:必须看清动作发出者是谁。例如:
Believe in yourself (你自己). (主语是you)
不能单独作主语:反身代词不能独立充当句子的主语。
(误) Myself did it.
(正) I myself did it. 我自己做的。
