Wonder why you can get angry so easily while your friend smiles all the time? It’s probably because you both have different personalities(个性).

Personality is also about how people think, behave, and react (反应) to everything around them from day to day.

So what makes people think and behave in certain ways?

Part of the reason is that people are born like this. A baby gets its blood type, genes (基因) and other physical things when it’s still inside its mother. These things may help decide what the baby will be like.

But one’s personality doesn’t stop here. Family life, school learning and life experiences can also make you the person you are. This doesn’t mean it’s impossible to change your personality. You can always try to make yourself better. Don’t get too worried about your shortcomings (缺点). Just accept them. This is a good way to start making changes.

If you don’t know how to make friends, find out why. Is it because you’re too shy? Tell yourself to smile at people. Start talking to people using warm greetings.

Don’t give yourself a hard time about it all. It’s not easy to change lifelong habits in one night. Keep working at it. One day you’ll see that you can turn over a new leaf and be a new you!

题型:计算题

(11分)如图甲,在水平地面上固定一倾角为θ的光滑斜面,一劲度系数为k的轻质弹簧的一端固定在斜面底端,弹簧处于自然状态。一质量为m的滑块从距离弹簧上端为s0处由静止释放,设滑块与弹簧接触过程中没有机械能损失,弹簧始终处在弹性限度内(不计空气阻力,重力加速度大小为g)。

(1)求滑块与弹簧上端接触瞬间的动能;

(2)若滑块在沿斜面向下运动的整个过程中最大速度大小为vm,求此时弹簧所具有的弹性势能;

(3)从滑块静止释放瞬间开始计时,请在乙图中定性画出滑块在沿斜面向下运动的整个过程中速度与时间的关系图象。图中横坐标轴上的t1、t2及t3分别表示滑块第一次与弹簧上端接触、第一次速度达到最大值及第一次速度减为零的时刻,纵坐标轴上的v1为滑块在t1时刻的速度大小,vm是题中所指的物理量。(本问不要求写出计算过程)
