一、情态动词should的含义及其用法1.should“应该、应当”，表示责任、义务。后接?动词原形?，且无人称和数的变化。否定形式为should＋not，可缩写为?shouldn’t?。动词原形shouldn’t

Youshouldn’trideabicycleinthemiddleoftheroad.你不应该在马路中间骑车。e.g.Studentsshouldfollowtheschoolrules.学生应该遵守校规。

2.用于征求对方的意见，should表示应当、应该。一般用于第一人称的一般疑问句或特殊疑问句中。e.g.ShouldIhelpwithLily’shomework？我应该帮助莉莉写作业吗？WhatshouldIdoformylittlebrother？我应该为我弟弟做什么？

3.表示推测可能性。e.g.Ms.Whiteshouldbeascientist.怀特女士应该是一名科学家。Lilyishard-working.She?should?dowellinthecompetition.莉莉很努力。她应该会在比赛中表现很好。should

二、反身代词1.反身代词的构成：人称数第一人称第二人称第三人称单数myselfyourselfhimselfherselfitself复数ourselfyourselfthemself

注意：第一和第二人称的反身代词由形容词性?物主?代词加self或selves组成。第三人称的反身代词由人称代词?宾格?加self或selves组成。反身代词意为“本人、亲自、自己”。物主宾格

2.含反身代词的常用短语：enjoyoneself过得愉快；byoneself独自，单独；learn...byoneself＝teachoneself自学；helponeselfto自便，随便吃……；dressoneself自己穿衣服；talktooneself自言自语。

e.g.WhenIfacedifficulties，Ialwayssayto?myself?，“Nevergiveup！”当我面对困难时，我总是心想，“永不放弃！”myself
