2 阅读理解。 Mark Twain was a great writer. He was born in 1835 in the USA. He was also a famous speaker. He was famous for his sense of humour. Many people liked to listen to his talk because he liked to tell some interesting stories to make people laugh all the time. One day,Mark Twain was going to a small town because of his writing. Before he was going to leave, one of his friends said to him that there were always a lot of mosquitoes in the town and told him that he"d better not go there. Mark Twain waved his hands and said, "It doesn"t matter. The mosquitoes are no relatives of mine. I don"t think they will come to visit me. " After he arrived at the town,Mark Twain stayed in a small hotel near the station. He went into his room,but when he was just about to have a rest, quite a few mosquitoes flew around him. The waiters felt very sorry about that. "I"m very sorry, Mr Mark Twain. There are too many mosquitoes in our town," one of them said to him.

9 已知函数f（x）= 3 sinωx•cosωx-cos 2ωx（ω＞0）的周期为 π 2 ，（1）求ω的值；（2）设△ABC的三边a、b、c满足b 2=ac，且边b所对的角为x，求此时函数f（x）的值域．
10 如图所示，一条上端固定的绳长l 1=7．5m，质量m=60Kg的特技演员从绳上端先沿绳从静止开始无摩擦下滑一段距离后，突然握紧绳子，与绳子之间产生f="1800" N的摩擦阻力。滑到绳子末端时速度刚好为零。求：（1）特技演员下滑所用的时间t．（2）在水平面上有一辆长l 2=3m平板车，其上表面与绳末端等高，车右端离绳末端s=4m，平板车能一直以v ="2" m/s的恒定速度向右运动，为了要让该演员滑下后能留在车上，则车启动后演员应在多长时间范围内开始下滑？（把人看作质点，人与车之间动摩擦系数μ=0.2， g取10m/s 2）
