Today computers come in all shapes and sizes.There were still big computers for companies or universities. There are other special computers for factories. These large computers tell the fatory machines what to do. But there are also small personal computers to use at home or in an office. There are even computers in telephones, television sets , and cars. These computers have to be small. They are so small that you cannot even see all their parts.
Computers are very useful, but they also can cause problems. One kind of problems is with the computer's memory. It is not perfect so sometimes computers lose important information. Another problem is with the machinery. Computers are machines, and machines can break down. When the computers break down, they may erase information, like chalk on a blackboard. Or they may stop doing anything at all. And there is another different kind of problem with computers. Some doctors say they may be bad for your health. They say you should not work with computers all day.

So (2)___________ different types of music have been called jazz at one time or (3)___________ that is hard to say what it really is. Jazz has always been considered (4)___________black music but when I first took an interest in it I used to hear white bands playing music that was like Louis Armstrong's in the 1920s. I found out (5)___________ that they learn to do this by playing his records over and over again until their style was (6)___________ to his for them to imitate him. Since then white singers (7)___________ Bob Dylan have rediscovered their own folk tradition, instead of borrowing from black roots. But the main changes since 1960 have been social and technical. One is that (8)___________have more money to spend on records at an earlier age than they used to, so Tin Pan Alley, the "pop music" industry, aims at the teenage audience. Another is that electronic equipment has developed (9)___________ extent that technicians are now capable of mixing sound to produce recordings that are quite different from a live performance. But the real problem with "pop" music is that Tin Pan Alley has always worked against (10)___________ a genuine music of the people. It takes everything original and natural out of it and replaces it with cheap commercial imitation.As the American folk singer, Woody Guthrie said: "They've always preferred the second-rate song.

we should visit our grandparents once a week. My parents want us to help a close relationship with our grandparents by visiting them regularly and making sure that they are not lonely.
every member of the family has to keep his or her room tidy. My sister and I have to make our beds every morning, and clean the floor and windows twice a week.
my sister and I must be home before 10 p.m. My parents are very strict and believe that setting a curfew will help us to become responsible, and stay safe and healthy.

A lot of people like to play their records as loudly as possible. The result is that the rest of the family and the neighbors often complain if they don't like the music. One answer to this problem is to wear headphones, but headphones are usually uncomfortable.
An arm-chair which has a record-player built into it has just been designed by a British engineer, Stephen Court.
The armchair looks like an ordinary armchair with high back. However, each of the two sides of the chair has three loudspeakers inside to reproduce middle and high sounds. Low sounds are reproduced by a pair of loudspeakers in a hollow space under the seat. Anyone who sits in the chair hears sounds coming from all around his/her head.
Because we cannot tell the exact source from which low sounds come, it doesn't matter that they come from underneath or behind. It is the higher sounds coming from the sides of the chair that create a stereo effect.
These sounds travel only a few inches to reach the listener's ears. Consequently, it takes only a little power to make the music sound very loud. Only a small amount of sound leaks out from behind the chair into the room to disturb others. Most of the sound is absorbed by the listeners.

In my opinion :
1. Because the photos they take can capture what can be said to be the most memorable moment in their lives. Besides, taking photos can help people relax
2. Because it can:
- bring your joy
- connect you with others
- documet your family's life
- motivate you to experience more
- help you noe your world and stay in the moment
....
3. It is a pity that there is no camera on a smartphone. Because we often have a habit of taking photos anywhere, and smartphone is an inseparable thing, we always use it and bring it. We can use the camera on the phone to save the beautiful sceneries, important data. You know, camera is also a very useful tool in daily work, even in legal work.
