( )35. Angela: I always feel sad for no reason in winter. I don't have interest in doing anything when it is cold and grey. How could I change the bad feeling
Let your stress go. Schedule your life properly. Don't be so busy, or you may do anything wrong. Make sure you have some quiet time to yourself.
Take a walk. Get out and get more sunlight each day can help you a lot. Some experts say that we usually feel bored or sad because we get less sunlight in winter than we do in other seasons.
Sleep enough. If you don't have enough sleep, you can not think clearly. So you need to have a good sleeping habit and go to bed earlier right now.
Do some exercise. To keep healthy, exercise is needed. If you don't like doing sports outside, you can do some sports at home. The best way is that you had better receive the flu vaccine(流感疫苗).
Have a healthy diet. Do not eat too much. If you get hungry easily, you can have more small meals rather than a larger one, and you can eat more fruit and vegetables.
F. Calm down before sleep. If you are excited and nervous before you sleep, you may have bad dreams. Do something relaxing to make sure your brain is peaceful, such as reading and listening to music.

（3）研究反射角与入射角之间的关系，应用到量角器；
（4）根据入射光线和反射光线的位置互换进行实验，观察反射光线与原来入射光线的关系得出结论。
解析：解：（1）硬纸板F的主要作用是：①显示光路，②验证反射光线与入射光线及法线在同一平面内；
（2）要探究光的反射规律，先让一束光贴着纸板沿某一个角度射到O点，量出入射角和反射角的度数，然后改变光束的入射方向，使入射角减小，再量出入射角和反射角的度数，与前一次实验量出的结果进行比较，即可发现反射角和入射角关系；
故选：D；
（3）实验中需要用量角器测量角的大小；
（4）如果让光线逆着OF的方向射向镜面，这时的入射角为原来的反射角，根据光的反射定律，反射角等于入射角，这时的反射角为原来的入射角，所以会发现光线原路返回，也就是在反射现象中，光路是可逆的。
