China has become a country with an increasing number of old people. By old people we usually mean persons over the age of sixty. We often call them senior citizens instead of old men to show our respect.
Most senior citizens retire or no longer work full-time. They usually live in their own houses not far from their children's, while the children of a few senior citizens have gone abroad and work or study far beyond the oceans. For certain senior citizens, tile years after retirement are not very enjoyable. First, they feel that their lives lose meaning for being at home all day. In addition, they may feel lonely, especially those without children around. Moreover, they become more concerned with their health, as they grow older, and worry a lot about their safety. At the same time, many senior citizens enjoy their lives. They feel free to do things they were not able to do when they were working and raising their families. They spend their time travelling, doing exercises or watching TV. They get together with their fellow members who have the common interests and equal free time.
In fact, there are some still continuing their work, not just for money, but to show their value. However, no one really wants to be old, and perhaps all like to be young forever.

Varieties of electronic gadgets, without which some of us can’t live, come into being. Despite their conveniences, they bring people much stress, so people have to balance their advantages and disadvantages before buying them.
I can’t agree more with the author. With the development of science and technology, more and more fantastic electronic gadgets come into being, which dazzles people. People can’t resist the temptation to buy and update them since these gadgets become outdated too quickly.
I have a lot of favourite electronic gadgets， one of which is a video MP3. As well as carrying my favourite music， a video MP3 player can play up to 150 hours of movies and TV programmes. However, it cost me 2，000 yuan. Besides, the loud volume will damage my hearing if I overuse it.
If I want to buy a necessary electronical gadget, the first factor that should be taken into consideration is whether it’s practical.

Cell phones have become increasingly popular in China these days. Wherever you go you can see people using cell phones. Many college students, even high school students, have cell phones.
Cell phones have brought people a lot of benefits, but the most important is that they are convenient. With cell phones in their hands, they can keep in touch with anybody they want. If they want to get some information from the Internet, they can easily have their dream realized via cell phones too. Furthermore, if someone has a heart attack or a traffic accident, a call to emergency hospital or to the police can quickly bring him the help he wants.
However, cell phones can also bring people problems. The most serious is the electric wave radiation which is thought to be harmful to users' brains. Another problem is that when people are having a meeting or having a class or at a concert etc, the ring of the cell phone may interrupt others. So I think people should use cellphones as little as possible and turn them off when they are attending important meetings or attending classes.
