LanguagePoints1.Intheyear2010,theworld’spopulationwasover7billionintotal.billion前有数词修饰时，billion不能用复数形式。eg：Wewanttwobillion.我们想要20亿。billionsof意为“数十亿的”，表示不确定的数量。eg：Therearebillionsofstarsinthesky.2.1.total(同whole)作形容词时，意为“总的；总计的”，一般在句中作定语。eg：Thetotalnumberofourclassis50.这些文具总花费为10美元。.intotal意为“总计；合计”。Intotalover1,000peopleattendedtheconference.共计一千多人参加了这个会议。Wecan’tliveinwater,andonlyaboutonethirdofourplanetisland.1.分数表达法：分子用基数词，分母用序数词。分子如果大于1，分母用复数形式。提示：二分之一不能说a/onesecond，而要说a/onehalf;四分之一和四分之三常用aquarter和threequarters表示。当分数＋of结构作主语时，谓语动词的单复数取决于of后面的名词，名词为可数名词复数，谓语动词用复数；名词为不可数名词，谓语动词用单数。Threequartersoftheinformationistrue.四分之三的信息是真实的。3.Antarcticaiscoveredwithsnowandiceallyearround.becoveredwith被……覆盖eg：我们的花园被花草覆盖着。Ourgardeniscoveredwithgrassandflowers.Step8：ExerciseFillintheblankswiththecorrectformsofthewordsinthebox.increasedrysurfacebilliontotal1．Thenumberofswimmershereis____quicklybecauseit’sveryhotthesedays.2．Theschoolhasa________of900students.3．Ithinkitmaybethe____seasonoftheyear.4．The____ofourbodyisskin.Itprotectsus.5．Howmany________ofpeoplearethereintheworldnow?Step9:Summaryplanet,billion,total,increase,surface,Indian,Atlantic,Arctic,intotal,onethird,twothirds,becoveredwith…,billionsofStep10:
