Most people may not think that there are any problems with watermelons, but some Japanese sellers do. There is often wasted space when they store watermelons, because round watermelons do not sit nicely on shelves. So some clever farmers have solved the watermelon problem. They make their watermelons grow in square glass boxes so the watermelons become square. The only problem now is the price. The square watermelons cost about 80 dollars each.
Many people know the saying "Roses are red, violets are blue, sugar is sweet and so are you." Well, today the poem needs to change to "Roses are red, roses are blue"! Australian scientists have just recently discovered that when they put a chemical from a blue flower into a rose, they can create a nearly 100% blue rose. Some of science's inventions are beautiful, not just useful!
Since the mid-1990s, many Chinese farmers have had amazing rice harvests. For many years Chinese scientists have been working on developing new kinds of stronger rice and now they have produced a new kind, called super rice. Super rice not only can protect itself against insects and diseases, but it also produces more than any other kind of rice, today farmers can grow almost one and a half times more rice than they could grow in the past.
Doctors might be able to use vegetables to fight cancer now. US scientists have discovered a way to put a chemical into tomato plants while they are growing. When cancer patients eat the tomatoes, the tomatoes will fight the cancer in their bodies. These cancer-fighting vegetables are not yet for sale, because scientists have not finished testing them. If study finds no problems with the tomatoes, then patients can begin to use this easy and delicious new treatment.

①Teens 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?
②A 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.
③First, 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.
④Second, 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.
⑤You 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 fruits 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.
