oday,thepopularityofbasketballhasrisenaroundtheworld,withmanyyoungpeopledreamingofbecomingfamousplayers.1)todayadv.修饰整个句子，表示当前的一段时间，相当于汉语“如今；当今”。e.g.Today,onlyafewkindsofthesebeautifulanimalsstillliveontheearth.现今，这些美丽的动物只有少数几种还生活在地球上。2)介词with与在意义上有主谓关系的复合结构manyyoungpeopledreamingof…构成短语，用作状语。4.Basketballhasnotonlybecomeapopularsporttoplay,butithasalsobecomeapopularsporttowatch.notonly…,butalso…不但……而且……若连接两个成分作主语，谓语动词与靠近的主语保持一致。e.g.Notonlythestudentsbutalsotheirteacherisenjoyingthefilm.不仅学生们在欣赏这部影片，他们的老师也在欣赏这部影片。5.Thenumberofforeignplayers,includingChineseplayers,intheNBAhasincreased.1)number表示数量。由于是单数形式，谓语动词需要与之相配，故为hasincreased。这种主语和谓语在数上的匹配称作“主谓一致”。当主语为复数概念是，谓语动词用复数形式与之匹配；当主语为单数概念时，谓语动词则用单数形式。e.g.Peoplethereareveryfriendly.people为复数概念。TheUnitedNationsisaninternationalorganizationthattriestofindpeacefulsolutionstoworldproblems.theUnitedNations是一个组织，为单数概念。2)thenumberof…“……的数量；……的数目”。作主语时，谓语动词应用单数形式。anumberof…“若干的，一些”，修饰可数名词。作主语时，谓语动词应用复数形式。e.g.Thenumberofpeoplekilledintheaccidenthasn’tbeenannouncedyet.这次事故中的死亡人数尚未公布。Anumberofpeopleareunhappywiththisdecision.一些人对这项决定并不满意。【运用】根据汉语意思完成英语句子，每空词数不限。(1)许多孩子正在花园里玩。______________________playinginthegarden.(2)花园里孩子的数量是六个。
