41、 with,together with,like(象),but(除了),except,besides,as well as，rather than(而不是),including,in addition to 引导的短语，谓语动词仍用单数。Air as well as water is matter.空气和水都是物质。No one except two servants was late for the dinner.除了两个仆人外，没有一个人迟来用餐。482不定式(短语),动名词(短语),或从句作主语时，谓语动词用单数。Serving the people is my great happin

44、一致。52巩固内化11My father,together with some of his old friends,_(be)there already.2More than one answer _(give)to the question.3Laying eggs _(be)the ant queen s fulltime job.4Each man and woman _(have)the same rights.5My blue trousers _ worn out.One pair of trousers_not enough.(be)6Many a student _(real

45、ize)the importance of learning a foreign language.has beenhas been givenishasareishas realized53二、意义一致原则意义一致原则指不管主语的形式是单数还是复数，主语的意义决定了谓语动词的单复数。1主语中有all,half,most,the rest等，以及”分数或百分数名词”作主语时，谓语动词单复数取决于连用的名词。The rest of the bikes are on sale today.剩下的自行车，今天出售。60%of the apple was eaten by the little boy

48、oys.2Most of his money _ spent on books.(be)3Half of the visitors _ from Europe.Half of the fruit _ bad.(be)4Five hundred dollars _(be)more than he can afford.5The policeman _ standing at the street corner.The police _ searching for him.(be)6The young _(be)the vital forces in our society.areisareisi

49、sisareare57三、就近一致原则就近一致原则指谓语动词的单复数形式取决于离它最近的主语的单复数。1由here,there等引导的倒装句中，有时主语不止一个时，谓语动词与靠近它的主语在数上一致。Here comes the bus.公共汽车来了。Here is a pen and some pieces of paper for you.给你一支钢笔和几张纸。582用连词or,either.or,neither.nor,not only.but also 等连接的并列主语，谓语动词与靠近它的主语在数上一致。Neither the students nor the teacher knows
