问题描述：
Most of what has been said about the Smiths______(be)also ture of the Johnsons.
意思
答
填is 当主语是从句时，谓语用单数
译：大多数对史密斯一家的言论同时也适用于约翰一家。
答
is
这里涉及到两个考点
1.most of + n.谓语动词是单数还是复数根据后面的名词判断,可数名词后面用复数,不可数名词后面用单数
e.g.Most of the students are interested in English.
Most of the rice is for the poor.
2.本句most of后面是个从句,从句一般属于单数.
综合以上,得出is.
意思：大多关于史密斯家的言论也适合约翰家.
