１．集体名词作主语时与动词的一致

当主语为furniture,equipment,machinery等词时，谓语动词通常用单数。

The furniture in that shop is all made in China.

Office equipment is very expensive nowadays.

集体名词如people,cattle,police,poultry等往往作复数用。

Some people drive madly in this country.

Many cattle have died because of the flood.

family,government,class,committee,audience,team,public等词被视作一个整体时，其后的动词用单数;被视为构成整体的个体时，其后的动词则为复数。

His family is a happy one.

His family are all interested in stamp collecting.
