1．动名词短语、不定式短语、名词性从句做主语,谓语用单数.如： Buying clothes is often a time-consuming job because those clothes that a person likes are rarely the cones that fit him or her. (1987年考研题) To understand the situation completely requires more thought than has been given thus far.

3．一般用and连接的两个单词或短语做主语时候,谓语用复数,但是下面用and连接的主语表示一个概念,谓语用单数： law and order 法制 soap and water 肥皂水 a cup and saucer 茶杯碟子 fork and knife 刀叉 the needle and thread 针线 trial and error 反复尝试,不断摸索 horse and carriage 马车 time and tide 岁月 bread and butter 奶油面包 the ebb and flow 盛衰,潮涨潮落 如： If law and order not preserved, neither the citizen nor his property is safe. A. is B. are C. was d. were 答案：A.
4．表示学科和某些疾病名称的名词是复数形式,作主语时候谓语动词用单数形式 Linguistics is a branch of study on human language.
5．有些名词形式上是复数,意义上是单数,根据意义一致原则动词用单数 The chaos was stopped by the police The news is a great encouragement to us A series of debates between the lectures was scheduled for the next weekend.
6．用and 连接的成份表示一个单一概念时候,动词谓语用单数形式 Bread and butter is our daily food Time and tide waits for no man《和3同》

二． 谓语用复数情况
1． 由and, both …and, 连接的并列主语,和both ,a few, many ,several 等修饰语后面谓语动词通常用复数形式. Few people know he and I were classmates when we were at college.

三．谓语动词可用单数,也可以用复数的情况
1． 就近一致原则 这种情况下,谓语动词使用单数还是复数取决于最靠近该动词的主语的单复数,存在这种情况的主要由以下几种可能：
1） 由连词 either…or…; neither…nor…; whether… or…;not only…but (also) ;or 等连接的并列主语 Neither money nor fame has influence on me Not only you but also he is wrong
2) 在倒装结构中,谓语动词与后面的第一个主语一致 Blocking the open-sided porch, framed by the enveloping fog, stands a tall grave-faced policeman. Just outside the ruins is a magnificent building surrounded by tall trees. Although a great number of houses in that area are still in need of repair, there has been improvement in the facili
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)

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
