A
Time flies when you have fun on your smartphone. But when you sit down to work and study, an hour feels like a year. ▲ It is all because of something small called dopamine which is a "joy chemical" that makes people feel good. Our brains（脑）release it when we eat yummy food, after we exercise or when we are praised.
Compared with studying, eating chocolate can make your brain release 150% more dopamine, and exercising for 30 minutes raises it by 200%. But using smartphones creates much more dopamine. For example, watching short videos gives a 250% increase, and checking new messages makes dopamine jump by 400%—much higher than studying. But why? When we go through social media, we don't know what we'll see next. This uncertainty makes dopamine active. Studying doesn't provide such uncertainty. Without the excitement of "gambling（赌博）", we get bored much more easily.
Can we do something to change that? According to research, apps can become less attractive if we turn off notifications（消息通知）or change the screen colours to black and white. We can also set time controls on apps. As for studying, you could check your progress daily or weekly and reward yourself for it. You could also explore interesting topics related to your textbooks.

D. Why are we so crazy about smartphones but easily bored with studying?
