Money can’t buy everything, but we need money in our life. If I have a lot of money, I will do a lot of things.

First, I want to build a nice house for my parents. Now I just live with my grandparents. My parents can’t afford to build one beautiful house, because the money my parents make is only used to pay for my study and everyday life. I feel sorry for them. So I will give a lot of money to my parents if I am very rich.

Second, I will give money to the poor children, then they can go to school and they can get knowledge（知识）. When they grow up, they can work for the country. Now in the 21^st century, knowledge is the most important thing. Can we say “Knowledge is money”? I think so. So I am sure we can have a nice future and a much stronger motherland.

At last I will go to the best medical college in the world, and also I will make a lot of medicine for different diseases of cancer（癌症）, and then I can help more people.

There are many things we will do if we have a lot of money, but now we have to work hard. So let’s work hard for money, and for our country!

Are you carrying too much on your back at school? You’re not alone. Back experts(专家) in the USA are worried about that young students are having back and neck problems because they are carrying too much in their backpacks .
“It hurts my back when I run,” said Ebelin Reyes, a student in Virginia. “It’s hard to get up the stairs with my backpack because it’s too heavy.” Students have to carry heavy backpacks on their backs for a whole week’s study. Ebelin is one of them. They have   regular(固定的)backpacks with two straps(带子) to carry them, but a number of students with heavy loads(负担) have switched to rolling backpacks. The backpacks have wheels and can roll on the ground. Shirley Park’s backpack weighs 10 kilos, and she said, “I’ll change to a rolling backpack because I am starting to have back pain.”
How much is too much? Experts say that students should carry no more than 10% to 15% of their own body weight. A few students have had a good idea to lighten(减轻) the load: less homework.
Doctor’s suggestions:
Lighten the load. Take home only the books the students need that day.
(2) Wide straps are better. They can send out weight over your shoulders (肩)and be sure to wear backpacks with two straps.
(3) The heaviest things should be packed closest to the back.
(4) Bend(弯曲) both knees when you pick up the pack, don’t just bend over the waist(腰).
