Are you carrying too much on your back at school? I’m sure lots of children of your age will say “Yes”. Not only the students in China have this problem, but children in the United States also have heavy school bags.
Doctors are starting to worry about young students’ back and neck because their school bags are too heavy for them.
“It’s hard for me to go upstairs with my heavy bag,” said Rick Hammond, an ll-year-old student in the USA.
Rick is among students who have school bags with two straps(带子),and many other students choose rolling(有滚轮的) bags.
But even with rolling bags ,getting upstairs is still a problem for children .Doctors say students should carry no more than 10% to 15% of their own body weight (重量)。
Scott Bautch, a back doctor, said children under Grade 4 should carry no more than 10% of their weight and older children shouldn’t stay with over 15% , because their bodies are still growing.
Teachers and parents should do some things to help children. And the best answer is to have less homework!

“I can’t believe what I’m hearing!” I thought to myself. Jeff was the last candidate* for president of Student Union. I really thought I should be chosen.
Later that day, I happened to pass Jeff in the dining room. I offered 1 a polite “Congratulations” and walked to my usual table. To my 2 , Jeff came to me and put his plate beside mine.
“I’m, er – I’m just wondering if you would consider coming to work on my team,” he said nervously. “You are really 3 and you would be a great partner.”
“I don"t think so,” I replied, feeling unsure.
“Well, 4 you change your mind, you can tell me tomorrow.” he said before moving to another table.
All that night, I thought about the 5 from Jeff. Maybe being a part of the election* process would give me a chance to make important changes at our school. I decided to 6 Jeff.
7 of all, I began to create a catchy*advertisement. Within a few days, we 8 a poster with Jeff’s pictures showing him in a number of activities. No one could walk through any hallway 9 passing Jeff’s smiling face.
My next step was to 10 what new activities students would like to have at our school. Many of them wanted a chess club and a volleyball team.
With the information I had collected, Jeff met with the headmaster. The headmaster agreed to add 11 we want to our school program.
With my help, Jeff and our ideas were well received at school.
An eighth grader said, “ 12 will be exciting to have Jeff as president.”
13 these words made my heart filled with pride. I had wanted to become president of Student Union to make a difference. Now I achieved that. Jeff became the most popular candidate and I was a large part of his 14 . The fact that it has made a 15 in other people’s lives is the real prize. What a great feeling!

Germs are always found in dirty water. When you look at dirty water under the microscope, you can see them in it.
Germs are found not only in water. They are also found in air and dust (灰尘). If you cut your finger (手指), and if some of the dust goes into the finger, it will become big and red, and you will have much pain in it. Sometimes germs will go into your body and you will have pain everywhere.

These 3 love their children and want to 4 that everything in their life is perfect. Some kids may become upset but 5 like being pampered(纵容). The pampered kids like the idea of being waited on hand and foot. They like the idea of not 6 to make decisions.

Sugar—free beets（甜菜）that still taste sweet, tastier tomatoes and brighter-colored fruits and vegetables that stay ripe（熟的）longer are all foods that are being grown now. How can they
carry traits, such as being tastier, brighter, and riper? They are genetically engineered.
Genetic engineering（基因工程）is like making a change in a recipe. For example, when you make cakes, you mix together all of the usual ingredients. If you add an extra ingredient, like salt, the cakes will taste differently.
Genes are ingredients in the recipe for life. They carry the traits of living things. Your genes dictate what color hair and eyes you’ll have, how tall you’ll be, as well as many other traits. Genes carry traits for plants, too. By adding genes to a plant, you can sometimes create new traits. For example, adding a certain gene to a potato plant can make the potato plant distasteful to bugs（虫子）. This makes some farmers happy because they don’t have to use chemicals to keep bugs away from their plants.
It sounds great, but some people are opposed to the idea of food that is genetically engineered. Ronnie Cummins, from the Campaign for Food Safety, is against it. He says that one of the major concerns is allergies（过敏）. Supermarkets don’t always label foods that are genetically engineered. A customer could unknowingly buy food that has an added gene from another plant that he or she is allergic to. It could be dangerous.
Gary Burton from Monsanto, a seed（种子）company that engineers food, disagrees. He says his company tests for allergies. Burton believes that genetic engineering is a valuable tool for making better food. The technology can help farmers use less insecticide（***虫剂）and grow healthier crops. Burton thinks there are many advantages.
But Cummins says that we just don’t know what will happen in the future if we keep adding genes to foods. We could mistakenly create a monster.
People have different opinions about genetic engineering. One side supports it and thinks it will only help us. The other side is opposed to playing with nature and fears health risks. Which side do you think is right?
小题1:What could be a good thing about food that is genetically engineered?| A．It’s more expensive. | | B．It could taste different. | | C．It requires less insecticide. | | D．It’s not labeled in the supermarket. |
小题2:In general, who does not support the idea of genetic food?| A．People from seed companies. | | B．Farmers who use engineered seeds. | | C．People from the Campaign for Food Safety. | | D．Scientists who create genetically engineered food. |
小题3:It can be inferred that .| A．growing genetic foods will make farmers richer | | B．people will eat more genetic foods in the future | | C．using fewer chemicals could make the food tastier | | D．there could be unknown dangers about genetic foods |
小题4:What is the best title of this passage?| A．Future Farming | | B．Genetic Engineering | | C．Foods with a Difference | | D．Genetically Engineered Fruits |
