有be happy to do这中句型么?谢谢. happy for sb to do sth有这个句型吗? be going to do之外有be going to doing有这个句型么, be happy to do sth 英语句型中it+be+of/for+to do be designed to do sth 是个固定句型,但为什么下面的句中 有两个 be 求There be 句型中to do和to be done 的区别-_-# 什么是to be 句型和to do 句型 有一篇英语短文,填空Do you want to be happy?Your () should be "yes",bu We wanted the children to be happy句型结构 be adj what/how to do 句型 There be+名词＋doing与There be+名词＋to do句型中doing和to do是否是在此种句型中作后
