　　2． 主语带有（together/along）with, such as, accompanied by, as well as, no less than, except, besides, with, combined with, in addition to , including, together with 等等附加成分，谓语的数不受附加成分的影响仍然与主语保持一致
　　Professor Taylor , with six of his students ,is attending a conference in Boston organized to compare current practice in the United States with those of other nations.
　　The president of the college, together with the deans, is planning a conference for the purpose of laying down certain regulations. (1981年考研题)
　　3．关系代词做主语的定语从句中，谓语的数要与先行词一致。如：

　　（1996年考研题）
　　There are many valuable services which the public are willing to pay for, but which do not bring a return in money to the community.
　　（1990年考研题）
　　4．一些表示数量的短语与名词连用时候，谓语动词的数取决于名词的数，名词是复数，谓语动词用复数，反之就用单数。这些短语包括：a lot of /lots of; plenty of/heaps of; half of; two-third (three-fourth…) of; eighty(ten, twenty…) percent; part of; rest of ; none of 等等
　　Two-thirds of people present are women
　　Lots of damage was caused by the fire
　　5．集体名词作主语时，谓语动词的数取决于主语表示的意思和数，当表示整体时候，谓语动词就用单数，当强调集体中的个体时候，谓语动词就用复数。这些集体名词如：army, audience, band ,government ,group ,flock, police, public ,staff ,team ,troop. Crowd, firm, family 等等
　　The family is the basic unit of our society
　　The family were watching the TV
　　The audience was enormous
　　The audience were greatly moved at the words
　　6．某些固定结构中主语与谓语的数：
　　第一组：
　　a great many + 可数名词复数 谓语用复数
　　a number of + 可数名词复数 谓语用复数
　　the majority of + 可数名词复数 谓语用复数
　　第二组；
　　the number of + 可数名词复数 谓语用单数
　　each/every + 可数名词复数 谓语用单数
　　neither/either of + 可数名词复数 谓语用单数
　　one and a half + 可数名词复数 谓语用单数
　　第三组；

　　many a + 可数名词单数 谓语用单数
　　第四组；
　　the greater part of
　　a large proportion of
　　50% of
　　one third of
　　plenty of
　　the rest of
　　谓语的数与of 后面的名词一致
　　第五组；
　　(n)either…(n)or….
　　not only….. but also ……
　　not …..but ……
　　谓语的数与主语的第二部分（即(n)or/ but also/ but引导的后面部分）一致.
　　注意比较：
　　More students than one have been referred to
　　More than one student is going to buy this book

　　（四）倒装结构
　　倒装是指句子成分不是按主语在前、谓语在后的正常语序排列，而是将谓语或谓语的一部分移到主语之前。倒装是一种修辞手段，目的是为了强调。倒装分为部分倒装和全部倒装，考试多为部分倒装。考生应掌握什么情况下需要倒装,并对倒装后的句子能够认出来，避免做题时候的盲目和迷茫。
　　一． 用全部倒装的情况
　　全部倒装一般是存在以下列副词开头的句子中，全部倒装的方法是把句子的主谓语序颠倒过来，把谓语移到主语前面：
　　1）出于修辞需要，表示方向的副词：out, down, in ,up, away, on。如：
　　Down jumped the burglar from the tenth floor when he heard someone shouted at him.
　　Up went the plane
　　2)出于习惯用法：here, there, now, thus, hence, then.如：
　　Now is your turn. There goes the bell.
　　Here is a ticket for you
　　There existed a certain doubt among the students as to the necessity of work
　　注意：here，there用于倒装结构时主语一般为名词，如果是人称代词则不需要倒装
　　“ where is the cup？” “Here it is！”
　　Here you are.
　　There he comes.
　　3)有时主语较长，为了使句子平衡，避免头重脚轻，主谓要全部倒装。这种情况多出现在主系表结构中。如：
　　Less important than ever is developing a meaningful philosophy of life.
　　In between these two extremes are those people who agree with the jury system as a whole, but feel that some changes need to be implemented to improve its effectiveness.
　　二． 采用部分倒装情况
　　部分倒装一般是把句子谓语的一部分（主要是助动词或系动词）放到句子主语前，构成部分倒装，而全部倒装则把句子的谓语（包括实义动词）都放在主语前
　　1．下列否定词及含有否定意义的词组修饰状语时，若置于句首，句子的主谓要部分倒装，：
　　never, no, neither, not only, hardly, scarcely, little, seldom, rarely, not until, nowhere, at no time, on no account, in no respect, in no sense, by no means, in vain, still less。如：
　　Not only is its direct attack on their discipline, it bypasses the essence of what sociologists focus on.
　　Under no circumstances should we do anything that will
