Change Your Life

Everybody wants to look good, especially young people. 【小题1】

1. Get into shape.

Exercising regularly not only keeps you looking your best, but also improves your health, reduces your possibility of getting certain diseases and gives you more energy.

Healthy adults need 150 minutes of moderate (适度的) aerobic activity or 75 minutes of vigorous (强有力的) aerobic activity each week. Moderate activities include walking and swimming, while vigorous activities include jogging, boxing, and playing basketball. You should do some kind of strength training at least two days per week.

Also, consider joining a gym or local sports team. 【小题2】

2. Keep a balanced diet.

【小题3】 Whether you want to lose weight or simply improve your overall health, what you eat matters.

Your diet should consist of fruits, vegetables, and whole grains. Read food labels and stay away from foods that contain too much fat and sugar. If you suffer from anxiety or depression, then cut down on alcohol and caffeine, as these drinks will make matters worse.

3. Change your clothes.

【小题4】 Make an effort to look your best on a daily basis. This doesn’t necessarily mean dressing fancifully (花哨地) or formally; rather, find clothes that are fashionable, affordable, and proper.

4. 【小题5】

Get a haircut or dye your hair a different color. Women with long hair should consider getting layers, bangs, or a short bob.

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.

   When the weather turns warm，everyone wants to be in or around the water. 【小题1】 Learning how to swim is important if you plan to be near water. Many organizations provide swimming instruction for people of all ages. Check to see what classes are available（可得到的）in your area.

【小题2】 Always swim with a partner，every time—whether you're swimming in a backyard pool or in a lake. Even experienced swimmers can become tired or get muscle cramps，which might make it difficult to get out of the water. When people swim together，they can help each other or go for help in case of an emergency.

Get skilled. Speaking of emergencies，it's good to be prepared. Learning some life-saving skills，such as CPR and rescue techniques，can help you save a life. 【小题3】 Check with your YMCA or YWCA，the local hospital，or the chapter of the Red Cross.

Know your limits. Swimming can be a lot of fun—and you might want to stay in the water as long as possible. If you're not a good swimmer or you're just learning to swim，don't go in water that's so deep that you can't touch the bottom and don't try to keep up with skilled swimmers. 【小题4】 But it's a pretty sure bet they'd rather have you safe and alive.

Swim in safe areas only. 【小题5】 No one can predict changing ocean currents（流），rip currents，sudden storms，or other hidden dangers. In the event that something does go wrong，lifeguards are trained in rescue techniques.

   Several recent cases of violence（暴力）against students at U.S. colleges have made global headlines，arousing questions about the safety of America’s campuses. Yet government data show that the number of violent assaults（袭击）at colleges actually has decreased in recent years. And most schools have worked to increase safety through technology and student behavior.

It’s also important for students to take responsibility for their own safety. Being familiar with local neighborhoods and campus services is key. Personal-safety expert David Nance says the most important thing students can do is be attentive-which means not being distracted by smartphones or other devices.

The website for the group PEACE OUTSIDE CAMPUS，formed in response to the murder of a student from the University of Delaware in her off-campus apartment in 2005，lists additional measures students can take：

1. Don’t walk alone after dark or while drunk. Contact a friend to take you where you need to go.

2. When driving，keep your doors locked，and park in well-lit areas.

3. Don’t wear earphones or play music so loudly that you are unaware of your surroundings.

4. Trust your instinct（本能）and don’t worry about overreacting. You’re better safe than sorry.

5. Avoid entering elevators with strangers. When this is unavoidable，stand by the control panel and，if faced with a threatening way，push the emergency alarm and all the floor buttons. Don’t press the stop button.

6. Don’t hold the door open for a stranger attempting to enter the house，even if it seems rude. Ask them to identify themselves.

7. Post the police’s and fire departments’ numbers by every phone，and put them into your cellphone.

8. Label your emergency contacts as ICE（In Case of Emergency）in your cellphone so officials will know who to contact for important personal or medical information.
