Wind turbines can be used.
1 built on sites，not interfere with bat’s migratory system.
2 The turbines would shut down at night
3 people would use radars to keep bats away.
听力部分：
Will not solve problem.
1. Turbines need to be built where there is wind such as on mountains. Bats live close to mountains.
2. Tall structures attract bats and it is where they choose to sleep. Bats can sleep in the turbines at night but when the turbines starting working in the daytime, this will alert and harm the bats.
3. Radar can damage bat’s reproductive system.
体育必修课 Mandatory Physical Course
Reading：一位大开云kaiyun(中国)开云kaiyun(中国)生写信给校长要求将体育课(Physical course)改为必修课而不是现在的选修课，理由有二：
开云kaiyun(中国)校健身房(gym)里基本上都是空的，没有开云kaiyun(中国)生进去锻炼，由此可见开云kaiyun(中国)生没有得到必要的体育锻炼，体育必修课可以强制开云kaiyun(中国)生获得锻炼和健身;
体育必修课(physical course required)可以使开云kaiyun(中国)生接触到以前从来没有接触的运动(sport)，对新的体育项目发生兴趣
Conversation：开云kaiyun(中国)生不同意信件中的内容，认为将体育课改成必修课并不是好主意，针对以上理由提出两点反驳：
健身房里面(inside)的情况说明不了开云kaiyun(中国)生运动的状况,外面的情况不可忽视(outside does count)。有的开云kaiyun(中国)生在健身房外打网球(play tennis outside the gym),有的开云kaiyun(中国)生从校外骑自行车到校内(ride bike from off-campus to campus)，这些都是运动;
体育必修课不能使开云kaiyun(中国)生产生新兴趣(explore new interests)。如果体育课改为必修，开云kaiyun(中国)生会选择他们"已经会的"或者"很擅长"的运动(choose the sport they have already known or they are good at),因为开云kaiyun(中国)生倾向于"行事谨慎"(play safe)。
