One day I discovered I was terribly tired out. I tried turning notifications (通知) off. But the fear of missing out something important made me check the phone more often than before. So, I simply stopped using my phone.
Well, to tell the truth, it was not simple at all. For the first couple of days, I had a big fear that all of my friends would soon forget about me. When I had a free moment, I had no idea what to get myself distracted (分心的) with, and the worries mixed with boredom kept bothering me.
However, after three weeks without a mobile phone, I started noticing changes—changes which I liked, and which drove me to not just continue the experiment, but in fact to reorganize some of my habits.
First of all, I noticed that I became much more focused (专注的). Before, while doing something, I would often find myself wondering what was going on online. After a month of staying away from my mobile phone, I found that the urge (冲动) was already not that strong and that my ability to focus improved.
I discovered that the world is a beautiful place. Before, I would look at it through my camera mostly: take a photo, post it, get some likes. Now, I saw beautiful people walking around and I sensed the seasons change. I could understand the actual beauty of the world, and I did not need anyone else to prove the value of this beauty through likes or shares.
Now, as 100 days have passed, I can say that the experiment was worth it. I am planning to stay away from my phone for as long as possible.

8.BC 根据折射率公式n=可知,折射率越大,光在介质中的传播速度越慢,所以激光在氙气中的传播速度比在玻璃中的快,选项A错误;作出激光的传播路线图如图所示,设光在玻璃中的折射角为θ,根据折射定律,有n==1.5,所以sin θ=,由几何关系得d=2h tan θ+H tan 30°,解得双层玻璃中间氙气的厚度为H=,选项B正确;激光在玻璃中传播的路程s1==,激光在玻璃中的传播速度为v=,所以激光在玻璃中的传播时间t1===,选项C正确;激光在氙气中的传播时间为t2==,所以激光从A到B的传播时间为t=t1+t2=,选项D错误。
9.CD 画出光路如图所示,光线在AB面上入射时与AB的夹角为α=45°,根据几何关系有tan β==,则sin β=,折射率n==,选项A错误;∠FCE=90°-α=45°,根据几何关系有tan∠FCE=, tan β=,CE=,联立解得CF=R,CE=R,选项B错误,C正确;光在玻璃砖中的传播速率v==c,选项D正确。
10.CD 玻璃砖转动后,画出此时的光路图,如图所示,则光屏上的光点相对于O1点向上移动,选项A错误;当α=30°时,入射角i=30°,根据几何关系可得θ满足tan θ===1,解得θ=45°,则折射角r=45°+30°=75°,根据折射定律可得=,解得折射率n=,选项B错误,C正确;发生全反射时,有sin C==,则sin α=sin C==,选项D正确。
11.答案 (1)A(2分) (2)5.650(2分) (2分)
(3)变小(2分)
解析 (1)水面中央产生亮斑,是因为小灯泡发出的光在该区域中能折射出水面。其余区域比较暗,是因为小灯泡发出的光在这些区域发生全反射,折射光线消失,故选A。(2)根据游标卡尺读数规则可得h=56 mm+10×0.05 mm=56.50 mm=5.650 cm,根据题意,设临界角为C,如图所示,由几何关系可得sin C=,由sin C=,联立解得n==。(3)由n=知,若水面的高度下降,即h变小,而折射率n不变,可知直径d变小,亮斑将变小。
12.答案 (1)0.508(2分) (2)B(2分) (3)626(2分) (4)变小(2分)
