Question

英语选择题---The disabled_______trades in special schools.
A.is taught B.are taught
C.be taught D.have taught
请问这题怎么选?涉及什么语法知识?

Answer 1

B.
如果主语由“the+形容词（或过去分词）”结构充当,表示一类人,谓语通常用复数.这类词有：
the blind
the brave
the dead
the injured
the old
the oppressed
the poor
the rich
the sick
the unemployed
the wounded
the young
例如：
The blind study in special schools.
这类形容词或分词如果要表示个体时,就要与名词man,person或表示人的单数连用.例如：an old man
a rich person
the (a)wounded soldier
有少数过去分词与定冠词连用时指个别,则用单数.例如：
The departed was a well-known engineer.
