Teens are gaining（增加）weight. Today most teenagers are at least one size larger than teens were 20 years ago. Even clothing sizes have changed. Did you know that a small today used to be a medium, 20 years ago?
A recent research shows 97％of teens need more exercise. It's bad news because too little exercise means you are missing a lot of good things in life. Exercise helps in two ways.
First，exercise helps your body. Physical activity can make your body strong. It can also keep you at a healthy weight. Doctors say that people who stay at a healthy weight have fewer health problems．
Second，exercise can help your mind. People who get plenty of physical activity might worry less and sleep better at night. You may even learn better in school. Students who are healthy can listen and understand better in class.
So you can change your life and be more active at any point. It's never too late. An article called “How to Limit Screen Time and Get Moving”gives these ideas：
Step away from the screen. Doctors call watching TV or playing video games screen time. You should have no more than two hours of screen time a day. You will enjoy life more if you live it instead of watching it！
Start slowly. An hour a day can seem like a long time. Start with 10 minutes of new activities every day. Add more as you get stronger. Think about walking. Take the stairs instead of the lift. You will feel healthier.
Make fitness fun. Find a sport you like. It doesn't need to be the traditional sports of basketball, soccer,or baseball. Those are all great sports and if you like them, play them. However,you can also try hiking,skateboarding,or even rope jumping. If you enjoy the sport,you will do it.
Choose food carefully. Help your family shop for healthy food. Read the labels（标签）.Look for healthy foods. Eat lots of fiuits and vegetables. Stop buying soft drinks and junk foods. You will feel better if you eat right.
Exercise with others. Find a friend or family member to exercise or play with you. You will have more fun and it helps keep you responsible for going.What is the main idea of Paragraph 1？

Honesty of American students
When I first arrived in America,I was surprised by the honesty of my classmates.Over my first month at school,I didn’t see or hear anyone cheating.I found two reasons for this.
First,if any student cheats,he or she will get punished.My school has a rule called the Honor Code.It asks students not to steal,lie or cheat.If someone goes against the code,he or she will have to leave the school.During my first year in the school,seven students left the school because of cheating.
Second,American students don’t care about scores as much as Chinese students do.They know that colleges will look at their all-round abilities instead of only scores.So they have fewer reasons to cheat.The writer didn’t see or hear anyone cheating when she first arrived in America, did she?
What is the Honor Code about?
What will happen if students go against the code?
Who does the writer think care more about scores, American students or Chinese students?
Do American colleges think all-round abilities are important for students?

A thirsty crow (乌鸦)comes across(偶然遇到) a bottle of water, but the water level is out of its reach. The bird then drops some stones into it and gets the water.
“It’s just a story,” you may think. But new research has found that crows’ brains may sometimes be better than those of 6-year-old children.
In a recent experiment, American scientist Corina Logan and her team caught six crows to test them. The crows and children had to choose between two sets of tubes(试管). They had to drop stones in and get water.
With the red set, when they dropped a stone into a wide tube, the water level raised in a connected narrow tube. The blue set of tubes, however, had no connection between them.
Children aged 7 to 10 were able to learn the rule. Children aged 4-6, however, failed.Five of the six crows failed the test. But Kitty, a 6-month-old crow, passed it. She put most of the stones into the red tubes.
So, could a bird be more clever than a kindergartner? Don’t be too quick to say no.The first paragraph is ______ about crows.

We all know that exercise is good for your health. But some kinds of exercise may be better than others. Running, for example, may help to protect against heart disease and other health problems. Running may also help you live longer.
Recently, researchers studied more than 55,000 adults. About a quarter of the adults have a good habit of running. The study found these runners were much healthier than non-runners. In fact, the runners lived, on average（平均）, three years longer than the non-runners.
Running may be good exercise, but it can be difficult on the body. Here are commonly shared ideas among fitness experts（健身专家） to lower the risk of injury（受伤） for people who are new to running.
⊙Take it easy.
Do not run too much, too soon or too fast. Most people get running injuries when they push themselves too hard. The body needs time to get used to increases in distance（里程） or speed.
⊙ Get good running shoes.
There is no single best shoe for every runner. You should find the shoe that offers the best fit and support for your feet. More importantly, you should have a new pair of shoes every 500 to 800 kilometers.
⊙Take good notes.
Take time after each run to write down notes about what you did and how you felt. Look for things that happen again and again. For example, you may find that your knees hurt when you run sometimes. But perhaps you feel great when you have a rest between running days. These notes will help you make the best plan for running.The writer wants to tell us in the first paragraph ____________.
