New technology rules the whole world now. But I still remember when I was a child, I did not have a cell phone or a computer because it was not necessary at all in those days. The Internet was not popular and the touch screen technology was unknown.

At this time here in the US smartphones are really a need, especially for young and business people. There are many applications (应用软件) really useful like maps, dictionaries, e-mails and games.

For me, I use my smartphone to check the weather and to look for something on the Internet and of course to keep communicating through calls and texts. Besides, I like music applications, GPS and Facebook.

Many tests have discovered that cell phones cause damage to us because they send out radioactive (具有放射性的) waves to our bodies and this could cause cancer.

Psychologists say that these devices can affect behavior and I believe everyone knows it is harmful to the eyes if we are sitting for a long time in front of the computer. However, it seems to be difficult for us to give up, even if we know how bad it is for our health. The use of technology becomes more and more important in our lives.

I think the use of technology has brought us unimaginable things. If we use technology correctly, I am sure it would be possible to decrease the damage to our bodies.

Keep in mind that it is important not to focus only on technology, but to spend time with our families and people close to us.

   Cellphones, tablets, and computers are keeping children and teenagers awake at night-even when they' re not in use, according to new research. A study published on Monday in JAMA Pediatrics says that media devices are causing kids to sleep less and reducing the quality of sleep that they get. This leads to trouble of staying awake the next day.

Researchers analyzed hundreds of studies of children and teens aged 6-19. The scientists found a strong and consistent association between the use of technology at bedtime and poor sleeping. The reason is not just that kids are staying up too late with their devices. Using a computer can overstimulate the mind and emotions, the researchers say. A smartphone or tablet also gives off a light that affects the body's natural timing. These factors contribute to poor quality sleep. And many kids could be at risk. According to the study,72% of all children and 89% of adolescents have at least one device in their sleep environment. Most of these devices are used near bedtime.

"The harmful association between screen-based devices and kids' sleep is a major public health concern," the study concludes. In their conclusion, the researchers urge parents to understand the damaging influence of device use before sleep.

   “The grass looks greener on the other side of the fence.” That’s an old saying in English. It means that other places often look better, more interesting than the place where you live. “Let’s go to KFC for dinner and then watch some Japanese cartoons!” We all know it: more and more Chinese kids love American and Japanese food and movies. Some people worry that young Chinese are beginning to feel that way. They see young Chinese ignoring（忽视）Chinese culture and, instead, buying Japanese cartoon books, watching Korean soap operas and even celebrating western holidays.

Foreign books and soap operas are good, but Chinese writers and actors are just as good. As for holidays, Christmas is nice, but it can never have the meaning for Chinese that the Spring Festival has, and the West has nothing to compare with the Mid-Autumn Festival. China has lots of cool things in its culture: calligraphy, Beijing Opera, quick meals on the streets. And let’s not forget the part of Chinese culture I like best: its friendliness. Not all countries are as warm as China.

It’s good to enjoy other cultures and learn from them, but they can never replace your own culture. It’s good to look on the other side of the fence, but make sure you take a good long look. You will find that the grass isn’t always greener.

Although some people become worried about that, I don’t think they should. Will we get more powerful without learning from other countries? Will Chinese people live more happily without American fast food? Besides, it’s fun to learn about different cultures. Chinese kids can learn about other cultures and have fun, but they also need to learn more about their own culture. Be proud of Chinese culture and of being Chinese!

【小题1】What do some people think of young Chinese?

A．They are foolish in learning our own culture.

B．They are ignoring our own culture.

C．They are interested in our own culture.

D．They are hating our own culture.

【小题2】In some young Chinese’s eyes, which of the following is not the “greener grass”?

A．Japanese cartoon books.	B．Korean soap operas.
C．Christmas.	D．The Mid-Autumn Festival.

【小题3】In the author’s opinion, what is the best feature of Chinese culture？

A．Friendliness.	B．Working hard.
C．Bravery.	D．Honesty.

【小题4】What is the best title for the passage?

A．Chinese culture and western culture

C．That grass is not always greener

D．Interesting western culture

   Ask someone what they have done to help the environment recently and they will almost certainly mention recycling. Recycling in the home is very important of course. However, being forced to recycle often means we already have more material than we need. We are dealing with the results of that over-consumption in the greenest way possible, but it would be far better if we did not bring so much material home in the first place.

The total amount of packaging increased by 12% between 1999 and 2005. It now makes up a third of a typical household’s waste in the UK. In many supermarkets nowadays food items are packaged twice with plastic and cardboard.

Too much packaging is doing serious damage to the environment. The UK, for example, is running out of it for carrying this unnecessary waste. If such packaging is burnt, it gives off greenhouse gases which go on to cause the greenhouse effect. Recycling helps, but the process itself uses energy. The solution is not to produce such items in the first place. Food waste is a serious problem, too. Too many supermarkets encourage customers to buy more than they need. However, a few of them are coming round to the idea that this cannot continue, encouraging customers to reuse their plastic bags, for example.

But this is not just about supermarkets. It is about all of us. We have learned to associate packaging with quality. We have learned to think that something unpackaged is of poor quality. This is especially true of food. But it also applies to a wide range of consumer products, which often have far more packaging than necessary.

There are signs of hope. As more of us recycle, we are beginning to realize just how much unnecessary material we are collecting. We need to face the wastefulness of our consumer culture, but we have a mountain to climb.
