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!

Today there are 6 billion people on the earth. By the year 2050 there may be 12.5 billion. There will be a lot of people to feed. We need more food.
One way to produce more food is by growing stronger plants. For thousands of years, farmers have made plants better. Every season, they pick the best plants for the next season. It works very slowly. Since 1983, scientists have been able to change plants more quickly by changing their genetic material(遗传物质). Foods from plants grown in this way are called genetically modified foods(转基因食品), or GM foods.
By changing the genetic material of a plant, it is possible to make new plants. They make plants which are strong against plant diseases. They can also help in our diseases: a kind of rice is being prepared, for example, which stops people from becoming blind.
Rich countries produce GM foods because they are easy to grow and bring in more money. Poor countries are interested in them because they help produce more food.
GM plants are not natural. No one knows how good or bad they are. Making GM foods is only one way of feeding people in 2050. There are strong feelings against them, because they are unnatural. They may feed people, then hurt them or their children later. But, both rich and poor countries are very interested in their use, and they are not going to go away. In 2050 we may think differently about them.
【小题1】GM foods ________.

A．are a quick way to produce food

B．grow in the wild

C．are safe

D．are grown only in rich countries

【小题2】Why do some people not like GM foods?

A．They are not useful.

B．They are not helpful.

C．They are not natural.

D．They are not cheap.

【小题3】From the reading we know that ________.

A．GM foods will disappear one day in the future

B．GM foods will not disappear in the future

C．people will not be interested in GM foods

D．people will have to stop using GM foods

In a few years, most people will know that a healthy, happy, loving family is a joy and it is a necessary part for building a strong society. But there are still some people who don’t believe family life can be an enjoyable experience.
Some people already accepted the idea of the “me generation” so they fail to understand that there is a time in life when they have to give up their time to something more valuable.
At a time when adults need to think about the needs of their family, they will be doing other important things. Some people will spend too much time working for a more powerful car or a bigger house so that they can proudly say that they have them. Some will be doing dangerous things so that they may tell their stories to their friends, and others will recite things like “ I must become the best I can be.”  or “I don’t want to be at the bottom.” The needs of their family will be forgotten and they never seem to have time for the family.
Many people have not experienced a strong helpful perfect family life, so they have never discovered its worth. Many people have always experienced family life as a flight, so they can’t find time and energy for work.
But it is really very important that we all expect good family relations. We need to realize and value the importance of what can be achieved by loving each other in the family. It is also important for our society to encourage family members to create happiness.
【小题1】What does the writer expect family life to be like?

D．A flight

【小题2】What is meant by “me generation”?

【小题3】Why haven’t some people discovered the worth of family life?

A．They are not married.	B．They grow in a happy family.
C．They don’t live with the family.	D．They have never enjoyed family life.

【小题4】What is the writer’s purpose of writer the passage?

A．To ask people to study family life.
