Question

高一英语题
It was five days since they _____(buy)this TV set.
They_____(mean)to see me off at the airport ,but they got there too late.
并讲出原因

Answer 1

1.had bought .这是since的用法,主语从句,since前要是过去时,后面就是过去完成时.如果前面要是一般现在时（即it is five days）,则since后用现在完成时.
2.had meant(meaned).have或者had meant 都表示“本打算”,但是由于后半句是过去式,所以此处是过去完成时.同理,如果后半句是they get there late,则 前面是 have meant (meaned).
