问题描述：
Beijing is one of the many cities in the World that —— now develpoing programs to restore their
historical buildings.A.is B.has been C.have been D.are 为什么不能选其他的?
答
that 引导的是定语从句修饰先行词cities,所以从句中的谓语形式应与先行词保持一致.这是个特殊的题型.这种题有两个类型：
1.Beijing is one of the many cities in the World that —— now develpoing programs to restore their historical buildings.
2..Beijing is the only one of the many cities in the World that —— now develpoing programs to restore their historical buildings.
当one前面特指时,定语从句修饰的是one；当one前面无修饰词表示泛指,则定语从句修饰cities.
再比如：
Barbara is easy to recognise because she is the only one of the women who ____ the evening dress.
此空只能填wears ,定语从句修饰one,其谓语用单数.
明白了吗?
