First, read the English article below.

It’s hard to concentrate on homework if you’re tired, hungry, or uncomfortable. Try to get plenty of sleep if you know you’ll have to do a bunch of homework the next day, and don’t try to work on an empty stomach or with a full bladder!  If you feel physically tense, do some yoga or light stretches before you begin to work. Doing breathing exercises can also help you feel more comfortable and alert. If you’re not already in comfy clothes, get changed before you start working. This may mean joggers, sweatpants, pjs, shorts, underwear, or even being completely naked. It's your choice. Your environment can make a big difference in how well you focus on your work. Before you begin doing your homework, find a spot that is quiet, well-lit, and gives you plenty of space to spread out.  You’ll want a place where you can sit comfortably, but don’t get too comfortable. If you do homework in bed or on a cozy couch, you may be tempted to fall asleep! If you have to work at home, ask anyone who lives with you to give you a little quiet time while you do your homework. If you’re constantly looking at your Facebook feed or checking your Instagram notifications, you won’t get much work done. Put your phone in a place where you can’t get at it easily, like inside your bag or in a desk drawer. Turn off notifications if they distract you.  If you can’t resist messing around on your phone or visiting time-wasting websites on your computer, consider installing an app or a browser extension that blocks tempting apps and sites. Don’t try to work with a TV or radio on. If you listen to music while you do your homework, choose something that’s quiet and not too exciting, like some gentle classical music. While you study, keep a bottle of water and some snacks on hand. Staying hydrated and eating healthy foods can help you wake up, focus, and stay alert. Choose foods that can help boost your brain power, such as:  Whole grains Healthy proteins, like fish, beans, or nuts Blueberries Leafy greens You’ll get burnt out and lose focus...
