Passage4

Sometime in the next century,the familiar early-newspaper on the front porch(门廊)will disappear.And instead of reading your newspaper,it will read to you.You'll get up and turn on the computer newspaper just like switching on the TV.An electronic voice will distribute stories about the latest events,guided by a program that selects the type of news you want.You'll even get to choose the kind of voice you want to hear.Want more information on the brief story?A simple touch makes the entire text appear.Save it in your own personal computer if you like.These are among the predictions(预言)from communication experts working on the newspapers of the future.Pictured as part of broader home based media and entertainment systems,computer newspapers would unite print and broadcast reporting,offering news and analysis with video images of news events.
Most of the technology is available(可用的)now,but convincing(说服)more people that they don't need paper to read a newspaper is the next step.But resistance to computer newspaper may be stronger from within journalism.Since it is such a cultural change,it may be that the present generation of journalists and publishers will have to die off before the next generation realize that the newspaper industry is no longer a newspaper industry.Technology is making the end of traditional newspapers unavoidable.
Despite technological advances,it could take decades to replace newsprint with computer screens.It might take 30 to 40 years to complete the changeover because people need to buy computers and because newspapers have established financial(财经的)interests in the paper industry.

Passage5

Many people hurt their backs when they try to lift heavy things from the floor.It is easy to hurt your back muscles when you pick up a heavy object.However,there is a correct way to lift things from the floor.If you pick up big or heavy objects correctly,you probably will not hurt your back.
To lift something from the floor correctly,first bend your knees and squat down. Keep your back straight.Don't bend over from your waist;keep your back and hips and waist in a line.If you bend over,the muscles in your lower back can become hurt very easily.If you keep your back and hips straight,the muscles are stronger,because they have much more support.The other muscles can then help the lower back muscles.
As you squat down,try to get as close to the object as possible.For example,if you are going to pick up a heavy box,squat down directly in front of it,maybe you will have to spread your knees and legs.Put one knee on each side of the box.Remember at all times to keep your back straight.
Put your hands under the object that is in front of you,between your knees.
To lift the object,you should stand up slowly.Use your muscles in order to stand up.In other words,lift with your legs,not with your back.
