主谓一致 ◆并列结构作主语时谓语用复数 Reading and writing are very important.
注意：
当主语由and连结时，如果它表示一个单一的概念，即指同一人或同一物时，谓语动词用单数，and 此时连接的两个词前只有一个冠词。
The iron and steel industry is very important to our life. ◆主谓一致中的就近原则 1）
当there be 句型的主语是一系列事物时，谓语应与最邻近的主语保持一致。
There is a pen, a knife and several books on the desk.. 2）
当either… or… 与neither… nor， 连接两个主语时，谓语动词与最邻近的主语保持一致。
如果句子是由here, there引导，而主语又不止一个时，谓语通常也和最邻近的主语一致。
Either you or she is to go.
/ Here is a pen, a few envelops and some paper for you. 3）
◆谓语动词与前面的主语一致 当主语后面跟有with, together with, like, except, but, no less than, as well as 等词引起的短语时，谓语动词与前面的主语一致。
The teacher together with some students is visiting the factory.
He as well as I wants to go boating. ◆
谓语需用单数的情况 1）
代词each和由every, some, no, any等构成的复合代词作主语，或主语中含有each, every, 谓语需用单数。
Each of us has a tape-recorder.
There is something wrong with my watch.
2）
当主语是一本书或一条格言时，谓语动词常用单数。
The Arabian Nights is a book known to lovers of English.
<<天方夜谭>>是英语爱好者熟悉的一本好书。
3）
表示金钱，时间，距离, 价格或度量衡的复合名词作主语
时，通常把这些名词看作一个整体，谓语一般用单数。(用复数也可，意思不变。)
Three weeks was allowed for making the necessary preparations.
Ten million dollars is a big sum of money. ◆指代意义决定谓语的单复数 1）
在代词what, which, who, none, some, any, more, most, all等词的单复数由其指代的词的单复数决定。
All is right. (一切顺利。)
All are present. (所有人都到齐了。)
2）
集体名词作主语时，谓语的数要根据主语的意思来决定。如family, audience, crew, crowd, class, company, committee等词后用复数形式时，意为这个集体中的各个成员，用单数时表示该个集体。
His family isn't very large. His family are music lovers.
但集合名词people, police, cattle, poultry等在任何情况下都用复数形式。
Are there any police around?
3）有些名词，如variety, number, population, proportion, majority 等有时看作单数，有时看作复数。
A number of +名词复数+复数动词。
The number of +名词复数+单数动词。
A number of books have lent out.
The majority of the students like English. ◆与后接名词或代词保持一致 1）
用half of, part of, most of, a portion of 等词引起主语时，动词通常与of后面的名词，代词保持一致。
Most of his money is spent on books.
Most of the students are taking an active part in sports.
2）
在一些短语，如 many a 或 more than one 所修饰的词作主语时，谓语动词多用单数形式。但由more than… of 作主语时，动词应与其后的名词或代词保持一致。
