严重的雾霾天气，对国计民生已造成了严重的影响，汽车尾气是形成雾霾的重要污染源，“铁腕治污”已成为国家的工作重点，地铁列车可实现零排放，大力发展地铁，可以大大减少燃油公交车的使用，减少汽车尾气排放。

若一地铁列车从甲站由静止启动后做直线运动，先匀加速运动20s达到最高速度72km/h，再匀速运动80s，接着匀减速运动15s到达乙站停住。设列车在匀加速运动阶段牵引力为1×10⁶N，匀速阶段牵引力的功率为6×10³kW，忽略匀减速运动阶段牵引力所做的功。

（1）求甲站到乙站的距离；

（2）如果燃油公交车运行中做的功与该列车从甲站到乙站牵引力做的功相同，求公交车排放气体污染物的质量。（燃油公交车每做1焦耳功排放气体污染物3×10^－6克）

    Today was a fun day. I walked to Mike's home in the morning. I studied English with him. We read funny stories together

    Then I went to a park by bike. I flew(fly的过去式) kites. It was a windy day. Suddenly my kite flew into the lake

    A dog saw the kite. He jumped into the lake and swam to it. Five minutes later, he gave(give的过去式) the kite back to me. I was very grateful to him.

(____)The dog jumped into the lake and swam to the kite.

(____)The kite flew into the lake.

(____)He gave the kite back to me.

植树节到了，老师带领同学们去植树，共植树360棵，平均每人植树多少棵?
