问题补充：
They have been given two tickets for the new play at the Grand Theatre.这里for是不是引导的状语从句?How many tress have been planted this year?Mary was asked to show me her new book.The mokey was seen to jump off
答案：
They have been given two tickets for the new play at the Grand Theatre.
for后面不是句子,所以肯定不是状语从句.for the new play是two tickets的定语.
a ticket for...“...的票”
后面三个句子是怎么回事?
