  Nowadays more and more people are talking about genetically modified foods(GM foods).GM foods develop from genetically modified organisms(有机体), which have had specific changes introduced into their DNA by genetic engineering techniques.These techniques are much more precise where an organis m is exposed to chemicals to create a non-specific but stable change.For many people, the high-tech production raises all kinds of environmental, ethical(伦理的), health and safety problems.Particularly in countries with long farming traditions, the idea seems against nature.

  In fact, GM foods are already very much a part of our lives.They were first put on the market in 1996.A third of the corn and more than half the cotton grown in the U.S.last year was the product of biotechnology, according to the Department of Agriculture.More than 65 million acres of genetically modified crops will be planted in the U.S.this year.The genetic genie is out of the bottle.

  However, like any new product entering the food chain, GM foods must be subjected to careful testing.In wealthy countries, the debate about biotech is not so fierce by the fact that they have a large number of foods to choose from, and a supply that goes beyond the needs.In developing countries desperate to feed fast-growing and underfed populations, the matter is simpler and much more urgent:do the benefits of biotech outweigh the risks?

  The statistics on population growth and hunger are disturbing.Last year the world ' s population reached 6 billion.The U.N.states that nearly 800 million people around the world are unhealthy.About 400 million women of childbearing age don' t have enough iron, which means their babies are exposed to various birth defeats.As many as 100 million children suffer from vitamin A deficiency, a leading cause of blindness.

  How can biotech help? Genetic engineering is widely used to produce plants and animals with better nutritional values.Biotechnologists have developed genetically modified rice and they are working on other kinds of nutritionally improved crops.Biotech can also improve farming productivity in places where food shortages are caused by prop damage attributable to drought, poor soil and crop viruses.

Every afternoon hundreds of thousands of youth fill Internet cafes, switch on a game console (游戏机), or otherwise sit down to enter fantasy worlds. I’m talking about video games. These games can be fun and exciting, but we need to look out when this pastime becomes an addiction.

Games are often quite exciting and dramatic, but they generally aren’t very intellectual. We don’t learn as much from them as we would only reading a book. Spending too much time playing them can take away our study time. We need to remember that we are students first. Nothing should ever get in the way of proper studying.

Video games can also be a bad effect on younger children who may be watching. Many video games are violent and the object in most of them is to kill the other player(s). This does not send the right message to the children who need to be told that violence is not acceptable and need to be taught how to deal with situations maturely. Even if we do need to sit down and play a violent video game, we need to make sure that it is not affect the younger people around us.

Playing a computer game in our spare time is not a bad thing. Games can be a great way to relax after studying, to connect to our friends, or just to help our creativity. However, games should not become the focus of our life. We need to make sure that laying games never interferes with our studies and that we aren’t thinking about them all day. If we ever find ourselves playing them too much, we need to break the addiction. If that happens, we need to step away from the computer or television screen and learn to spend our time more productively.  

The writer mainly tells the readers __________.

to play computer games every afternoon

not to play computer games too much

not to affect other people while playing games

to spend more time studying

The writer thinks about computer games all of the following except _________.

A. exciting           B. dramatic           C. intellectual          D. violent

Computer games may have bad effect on younger children because __________.

these children often stay in Internet cafes all day long

children often forget to do their lessons

computer games are often violent

children don’t have enough money to play computer games

The writer advises computer game players ________.

When I asked my daughter which item she would keep: the phone, the car, the cooker, the computer, the TV, or her boyfriend, she said, “the phone”. Personally, I could do without the phone entirely, which makes me unusual. Because the telephone is changing our lives more than any other piece of technology.
Point 1. The telephone creates the need to communicate, in the same way more roads create more traffic. My daughter comes home from school at 4:00 pm and then spends an hour on the phone talking to the every people she has been at school with all day. If the phone did not exist, would she have anything to talk about?
Point 2. The mobile phone means that we are never alone.”The mobile saved my life,” says Crystal Johnstone. She had an accident in her Volvo on the A45 between Otley and Skipton. Trapped inside, she managed to make the call that brought the ambulance to her rescue.
Point 3. The mobile removes our secret. It allows marketing manager of Haba Deutsch, Carl Nicolaisen, to ring his sales staff all round the world at any time of day to ask where they are, where they are going, and how their last meeting went.
Point 4. The telephone separates us. Antonella Bramanate in Rome says, “We worked in separate offices but I could see him through the window. It was easy to get his number. We were so near---but we didn’t meet for the first two weeks!”
Point 5. The telephone allows us to reach out beyond our own lives. Today we can talk to several complete strangers simultaneously(同声翻译地)on chat lines (at least my daughter does. I wouldn’t know what to talk about). We can talk across the world. We can even talk to astronauts (if you know any) while they’re space-walking. And, with the phone line hooked up to the computer, we can access the Internet, the biggest library on Earth.
【小题1】Point 1 mainly tells us that __________.

A.The writer’s daughter enjoys talking on the phone
B.More roads create more traffic
C.phones create the need to communication
D.it’s easy to communicate through phones
【小题2】People’s attitude towards mobile phone is that it _________.
A.helps people deal with the emergency
B.brings convenience as well as little secret to people
C.is so important and should be encouraged
D.is part of people’s life
【小题3】It is possible to talk to several complete strangers at the same time through_____.

【小题4】Which is the most suitable title for the passage?
A.Phone PowerB.Kinds of Phones
