Trees help to keep the air clean and make us healthy. They take in dirty air and give clean air to us. Go for a walk in the park in the morning, and you can feel how nice it is to be with many trees and clean air.
Trees also give us many kinds of beautiful flowers and delicious fruits such as apples and oranges. Trees give homes to different insects, birds and other animals. Even the sap (汁液) of trees is useful as food for insects.
▲ We can use them in many ways. But we are hurting them and they can’t grow back quickly. We cut down trees to make paper, desks and chairs. Also, we sometimes clear (清空) the forest to make space to build houses, shops and so on. Clearing the forest is bad. Many animals lose their homes because of this.
It is time for us to stop hurting our great friends—trees. Use not as much paper and join tree-planting activities. All of us can do something for our dear friends!
37. How do trees help us stay healthy
A. They clean the air. B. They share their sap.
C. They make us enjoy flowers. D. They give us delicious fruits.

【解答】解:如图
当小球运动至A处,由题意可知,只有A处以内的地球部分对小球作用力产生加速度,满足,又有,联立解得,小球靠近地球球心过程,r减小,a减小,做加速度减小的加速运动,到球心另一侧时,由对称性可知,小球做加速度增大的减速运动,故A正确,BCD错误。
故选:A。
精确的实验发现,在地球表面不同的地方,g的大小一般是不同的。在赤道的海平面处g为9.780m/s2,在北极处g为9.832m/s2。已知地球质量为M,引力常量为G。将地球视为半径为R、质量均匀分布的球体。在北极有个矿井,矿井深度为d,质量分布均匀的球壳对壳内物体的引力为零。将质量为m的待测物体悬挂在弹簧测力计上,处于静止状态,下列说法正确的是(  )
A.在北极处,弹簧测力计读数
B.在赤道处,弹簧测力计读数
C.在北极沿地轴方向深d的矿井内,弹簧测力计读数为
