主语时，谓语动词只能用单数形式。注意：none与noone/nobody的区别：none既可指人也可指物，通常与表范围的of短

语连用；noone/nobody只能指人，不能与of短语连用。(2)none与数量有关，可回答howmany问句，表

示“一个也没有”；而noone表示“什么人也

没有”，可回答who问句。—Itriedseveralwaystoworkoutthemathproblem,but______

意为“孤单的，独自的”，

只能作表语。我独自在教室里。Iwasaloneintheclassroom.alone还可作副词，意为“只有；仅仅；单独地”。你不能仅靠面包维生。Youcan’tliveonbreadalone.辨析：alone与lonely

alone侧重于说明独自一人，没有人陪伴，不强调主观感情；而lonely形容人时，则表示情感上“孤独的；寂寞的”，常作表语。串记：Mygrandmotherlivesalone,buthedoesn’tfeellonely.WritingLookatthepicturefromasciencestoryforchildrenandanswerthequestions.5Whathavethescientistsjustreceived?(amessagefromoneofourspaceships)Theyhavejustreceivedamessagefromoneofourspaceships.1.Wherehasthespaceshiplanded?(Mars)IthaslandedonMars.
