To become a flexible reader, you need to know how to select and use a reading style that is consistent(一致的) with your purpose of reading. 【小题1】 Each has its own purpose. Read to learn about the three reading styles used by flexible readers.

   Some people don't wish to waste even a second at work. Looking at a computer screen for a long time can cause stress on one's eyes. Sitting and looking at a television screen for hours can also make the eyes tired.

Bookworms love reading and they will make sure they read much more than their bodies can deal with. The strong wish to finish a book may result in fast reading，without taking breaks, which can lead to tired eyes. Reading for a long time in weak light can also cause tired eyes.

More salt-based junk food like burgers，pizzas, etc. and less water also play a role in causing tired eyes. The junk food is a reason for tired eyes for it hasn't enough vitamins（维生素）.

Less sleep causes the eyes to become heavy. Dark circles also develop if one doesn't get enough sleep over a period of time.

If not treated in time，the condition can become worse. Here are some ways to relieve（减轻）a tired eye condition.

Every hour during your day at work, spend a minute relaxing your eyes. Look away from your computer screen and roll your eyes in all directions. Try and blink（眨眼）more often. Look around the room or close your eyes for a minute if you want and then work again. Following these every hour will help relieve the stress on your eyes，and you won't feel so tired after work.

Tea helps relieve tired eyes. Make a cup of hot black tea and pour it into a glass. Hold the glass close to your eyes，so that the vapors from the tea reach your eyes. This will also make you feel fresh.

If your eyes feel very tired at work, go to the washroom and wash your face with cool tap water. The cold water will help relieve the tired feeling. Do this every hour during work and your eyes will feel good.

   Do you want to be at the top of your class？Add these tips to your life and you should be on your way to being a top student！

【小题1】 I cannot stress（强调）enough how important it is to pay attention to what your teacher is teaching you. Take part in class discussions if you have something worthwhile to add. Pay attention during class, especially during lectures.

Taking notes is important. You don't need to write down every word your teacher says but write down what he writes on the board, or any special fact you think you might need for a test.【小题2】 This way it will help you learn more effectively by actually thinking about what you are writing.

Don't skip school（逃学）.You will be missing out on stuff.【小题3】 However, you will have more work because you have missed lectures. Also, try not to be late for class. It's most likely that your teacher won't appreciate it and you will get yourself behind.

【小题4】 If you have an "I don't care about school or this class" attitude, then teachers will be less willing to offer you extra credit（学分）.The same goes for lazy attitude. Have a respectful attitude to the teacher and other students. Try not to laugh when other students make a mistake.

Always ask questions.【小题5】 If you don't understand, ask someone. Read your textbook and notes, and then if that fails, seek help. Ask a teacher, friend, classmate, parent, etc. Get a tutor if you need one.

How teens can stay fit

Any type of regular physical activity can improve your fitness and your health.【小题1】

Exercise should be a regular part of your day, like brushing your teeth, eating and sleeping. It can be in a gym class, joining a sports team, or working out on your own. Keep the following tips in mind:

【小题2】A good attitude is important. Find an activity that you think is fun. You are more likely to stick with it if you choose something you like. A lot of people find it's more fun to exercise with someone else,so seek a friend or family member to be active with you.

Take it one step at a time.【小题3】For example, walk or ride your bike to school. Get on or off the bus several blocks away and walk the rest of the way. Use the stairs instead of taking the elevator.

Get your heart pumping. Whatever you choose ,make sure it includes aerobic （有氧的) activities that make you breathe harder and increase your heart rate. This is the best type of exercise because it increases your fitness level and makes your heart work better.【小题4】Examples of aerobic activities are basketball, running, or swimming.

Don't forget to warm up. Do  some  easy exercise or stretch （伸展) before you do any physical activity.【小题5】It is also important to stretch out after you exercise to cool down your muscles.

   Do teenagers know how to sleep? If you’re the parent of teens, you might be laughing to yourself. That’s all they know how to do. In truth, teens might not know enough about how to sleep, when to sleep and why.【小题1】 .

Just as we focus on our diets and exercise for health, we need to consider sleep necessary to our mental, physical and psychological health. “Good” sleep is sleep that is long enough to allow your brain to remove the side effects of daytime brain activity. Consistent bed times and wakeup times are the key to keeping our sleep cycles.【小题2】.

Teens are social creatures, and the most attractive social “gathering” place these days is on their digital devices.【小题3】. Ideally, we should avoid blue light for at least half an hour before bed. But social media and homework that requires screen time mean too many kids are powering up their devices when their bodies should be powering down for the night.

【小题4】. Equally contributing to sleep issues are eating too late, taking naps, and failing to get enough exercise. In other words, these people never learned how to sleep.

Over time, poor sleep leads to a decline in mood.【小题5】. Significantly, when I speak to my adult patients who are struggling with sleep issues, nearly all of them say their sleep problems started in high school.

Therefore, I recommend sleep education. Otherwise, we won’t necessarily solve the health, safety and economic issues of sleepy teens.
