B.Howfast

C.HowoftenD.Howlong中考鏈接hundred前加基數(shù)詞，表示“一百、二百、三百……”，hundred要用單數(shù)形式；hundred與of連用表示“數(shù)百”時，hundred要用復數(shù)形式，即hundredsof。thousand,million,billion和hundred的用法相同。2.Noneofthemhasanenvironmentlikethatoftheearth...none“沒有一個”做主語時，謂語動詞可用單數(shù)形式或復數(shù)形式。none與of連用表示范圍，后接不可數(shù)名詞做

主語時，謂語動詞只能用單數(shù)形式。注意：none與noone/nobody的區(qū)別：none既可指人也可指物，通常與表范圍的of短

語連用；noone/nobody只能指人，不能與of短語連用。(2)none與數(shù)量有關，可回答howmany問句，表

示“一個也沒有”；而noone表示“什么人也

意為“孤單的，獨自的”，

只能作表語。我獨自在教室里。Iwasaloneintheclassroom.alone還可作副詞，意為“只有；僅僅；單獨地”。你不能僅靠面包維生。Youcan’tliveonbreadalone.辨析：alone與lonely

alone側(cè)重于說明獨自一人，沒有人陪伴，不強調(diào)主觀感情；而lonely形容人時，則表示情感上“孤獨的；寂寞的”，常作表語。串記：Mygrandmotherlivesalone,buthedoesn’tfeellonely.WritingLookatthepicturefromasciencestoryforchildrenandanswerthequestions.5Whathavethescientistsjustreceived?(amessagefromoneofourspaceships)Theyhavejustreceivedamessagefromoneofourspaceships.1.Wherehasthespaceshiplanded?(Mars)IthaslandedonMars.
