参考答案：
1.is。表示时间、金钱、距离、重量的复数名词作主语,通常看作整体,谓语用单数。
2.are。如果“one and a half+复数名词”作主语,指时间时谓语用单数,如下题。
3.is。
4.are。有些用来表示由两个相同部分连成一体的复数名词,如:trousers,glasses等作主语,前面若无“一条”、“一副”、“一把”之类的单位词,通常作复数用,谓语用复数;若带有单位词,则由单位词的单复数决定谓语动词的单复数。再如:My blue trousers are worn out./There is a pair of glasses on the desk.
5.are。有些集体名词,如cattle,police,people等,形式上是单数,但几乎总是被用作复数,谓语动词需用复数。
6.like。有些以-sh,-ese,-ch结尾的表示国家、民族的形容词与the连用时表示复数意义,谓语用复数。再如:The Chinese are brave and hardworking people.试比较:The Chinese people is a GREat people.这里的people指一个民族。
7.are。有些集体名词,如family,class,group,team,enemy等作主语时,若作为一个整体看待,谓语用单数;若着眼于组成该集体的一个个成员或个体时,谓语就该用复数。本题的关键词是“well”,well在这里指身体健康,显然强调的是家庭的每个成员。试比较:His family is a “five-good”one.
8.are。一些表示部分概念或不定数量的名词或代词作主语,形式上为单数,但谓语动词的单复数应根据of后接名词的单复数形式而定,这类结构有half of,most of,the rest of,some of,lots of,plenty of,percent of,分数+of等。
9.are。不定代词all,any,some等作主语,谓语的单复数应根据上下文或具体场合而定。本题中的“All”指“All the people”。
10.are。引起主语从句的连接代词what的单复数取决于后面表语的单复数。
11.has。在这种句型中,one前若有定冠词,定语从句中的谓语动词用单数形式;one前若无定冠词,定语从句中的谓语动词用复数形式。
12.is。用and连接的名词作主语,谓语通常用复数。但如果and连接的两个名词指同一个人、同一件事或同一个概念时,谓语则用单数。“bread and butter”表示一个整体概念。
13.is。由and连接作主语的两个单数名词,前面分别有every,each,no,或many a等修饰时,其谓语动词用单数。
14.am。由or,either...or,nor,neither...nor,not only...but also等连接的并列主语,谓语动词的单复数与最邻近的主语(即后一个主语)保持一致。
15.has。后面跟有as well as,with,but,except,together with等短语,似乎都是主语,但谓语动词应与前面真正主语保持一致。
16.is。“more than one+单数名词”和“many a +单数名词”作主语,尽管意义上是复数,但因中心词是单数形式,谓语也用单数。
17.are。population作主语时,相当于“the number of the people”,谓语用单数。但当population被分为若干等份时,谓语动词常用复数。
18.have。each作同位语时,谓语用复数。
