People have always wanted to know what our future will look like. Go on reading this text, and you will know what will happen in the next fifty years.

    How can we know what the future will look like? To be able to understand the future, you have to know the past, what has taken us to where we are today and what has changed along the way? The world has changed a lot in the last 150 years, but people are driven by the same basic needs as they were 150 years ago. Will this change in the next 150 years? No.

    What inventions have really made a different in the last 150 years? In the past years, the inventions that have changed most people's everyday life are telephone, radio, television, computer, the car and the internet. Then we of course have a lot of inventions that have made life easier, like new medicine, faster cars, trains, etc. In general, people have been working hard in the last 150 years to make inventions that will make the world a better place. Since there is still much to do in the area, this will be important for at least the next 150 years.

    Why do we need to guess the future? Guessing the future is important for two reasons: First, we need to start to think about what kind of future we would like for ourselves and our children. And then we need to know what decisions we need to make today that will give us the best future.

    Each summer, you hear news that some sports players are sent to hospitals because it is too hot. Our bodies can't be outside in the sun for a long time. So in hot summers, be careful about playing sports outside.

    Firstly, to play sports safely in hot weather, you must drink water. Sports drinks are great for athletes, but they have so much sugar that they'll dehydrate（使脱水）you more. However, drinking afew bottles of sports drinks will be good for you.

    Secondly, be sure to take enough breaks to let your body rest. If your coach doesn't let you do so in the heat, don't wait until you feel uncomfortable. Just be honest with your coach when you need breaks.

    Thirdly, when you have a break, don't sit in the sun. With the sun beating down on you, you'll only heat up and sweat（冒汗）more. Take a seat under a tree, or even better, go indoors for a little while.

    Cooling yourself down can help you stay active longer.

    Fourthly, remember that the earlier in the day you start your exercise, the cooler it will be. If you can start practice before the sun comes up, you have a few good hours to practice in the cool hours of the morning. Also, the earlier you practice, the earlier you can finish the exercise. If you need more practice time, come back to the field later in the evening when the sun is setting.

Last but not least, you should watch your food. Eat food which is high in water, starch（淀粉）and carbohydrate(糖类), but be sure to get a good balance in your diet.

    As long as you pay attention to the above, playing sports safely in the heat isn't a difficult thing.

    My mom hates to cook. She'd rather ride her motorcycle or practice rock climbing. She also spends a lot of time with me. Every morning Mom takes me to school by motorcycle. Occasionally I'll come home to find her scaling(攀爬)the side of the house.

As her daughter, I used to feel embarrassed that my mom was so different. But now________.

    It all started with a cooking project. Every student in Mrs. Maitland's home-economics class was supposed to create an original dish, then present it at school the following Tuesday morning. Mom and I spent hours in the kitchen. We tried jelly-filled hot dogs, baked ham with chocolate sauce, and hard-boiled eggs rolled in coconut. We eventually agreed on chocolate cakes with bright green pepper mint frosting. I was satisfied. It beat hot dogs, anyway.

    The big day came. Our parents appeared, bringing many tasty dishes. Finally, I saw Mom, empty handed! I met her at the door. "You forgot it, didn't you?"

    Mom's eyes opened wide. "I'm sor--" She couldn't finish her apology. A loud alarm cut her off. Mrs. Maitland yelled, "Fire! This is not a drill! Everyone out of the building!"

    We all headed for the stairs and gathered at the parking lot. Smoke started to curl out of one of the third-floor windows. Mom held my hand tightly. I forgot about my cake.

    Suddenly, we heard a scream. We looked up and found Danny Patterson was trapped in the burning building! Mom disappeared. She grabbed her climbing tools from her motorcycle and walked quickly toward the building.

    She scaled the huge pine tree next to the school. At the top, she started to throw her weight back and forth. The tree swung toward the window, and she hopped onto the ledge and into the building.

    Mom's ropes flew as she created a harness. She secured one end, and then lowered Danny safely to the ground. Everyone cheered!

    Who cares if my mom hates to cook?
