Have you ever swum in the Blue Water World in the Oriental Suntown which has been set up in Taizhou? There a beautiful swimming pool has been built . Many high buildings have been set up.

Step3: Presentation Learning the structure .Give some explanations (1) 构成：现在完成时主动语态 : have/has (not) done sth 现在完成时被动语态 : have/has (NOT) been done Eg. He has been sent to study the new technology in the company. The dirty clothes have not been washed. Have the windows been cleaned? How many shopping centers have been built in this city? (2) 只有及物动词才有被动语态，不及物动词（词组）没有被态, 如:happen, take place, die, appear, disappear, fail, remain, lie, last, sit ,stand, break out, come true, belong to 等．如： What has happened to your brother?
