With a large part of the world's population living close to the oceans, rising sea levels bring the potential for destructive (破坏性的)results. But scientists are still unable to make predictions exact enough for people to plan to handle the loss of land and the threat to coastal communities expected over this century.
“We know sea level is going to rise, but how much, and how fast, and where, we really still don’t know," said Josh Willis, a climate scientist.
The ocean isn't like water in a bathtub. It doesn’t rise all the same as more water pours in. As global warming raises sea levels, some places are expected to see higher-than-average increases, and a few places, may even see decreases.
It’s reported that over the course of this century, sea levels will rise between 8 inches and 6.6 feet around the planet. Scientists know this increase will be driven by the expansion of water as it warms—warmer water takes up more space—and the melting of ice. But the effects of warming water and melting ice on sea-level rise are expected to vary from area to area. And the melting of ice of the Antarctic and Greenland presents the largest uncertainty for the future, but air, land and water also play roles in changes to sea level. For example, sea level near the ice getting melt actually decreases, because the ground under the melting ice rises as the heavy ice disappears.
Climate change is expected to change ocean currents and the winds that help drive ocean currents. These changes will affect the distribution of heat within the oceans, and, as a result, affect changes in sea level.
Nowadays, scientists use two types of models to make predictions about the future of sea levels, but the two don’t agree. If scientists can't accurately predict sea-level increase for the coming years, the least we can do is measure what happening today with the help of the satellite, Jason-2, but it’s reaching the end of its operational life.

Maybe you don’t think animals have certain mental powers which human beings do not have. But the truth is that some of them have instincts, and besides this, I am sure they can feel certain things we humans cannot. A personal experience showed me this.
Some years ago, I had a dog named Howard. From the time when he was a puppy, he was timid, so we named him Howard, sounding like “coward”! He was especially afraid of thunderstorms. At the first flash of lightning or crash of thunder, he would run whining into his house and hide under a table.
I often went for a walk with Howard. Once, as we were walking along a road, it began to rain. I quickly ran to a bus stop for shelter. The bus stop had a roof supported by metal poles. Soon after I had got there, Howard caught my trousers in his teeth and tried to pull me away. At first I was puzzled and a little angry at his behavior. But I decided to humor him and walked away from the shelter into the rain and started to go home.
When I was about two hundred metres from the shelter, there came a flash of lightning and soon after, there was thunder which nearly deafened me. Howard stopped walking and began whining. Thinking he was afraid, I bent to pick him up. As I straightened up, I glanced at the bus shelter we had just left. I was shocked to see that two of the poles were bent and the roof was lying on the ground, broken. The shelter had been struck by the bolt of lightning!

Sometimes you’ll hear people say that you can’t love others until you love yourself. Sometimes you’ll hear people say that you can’t expect someone else to love you until you love yourself. Either way, you’ve got to love yourself first and this can be tricky. Sure we all know that we’re the apple of our parents’ eyes, and that our Grandmas think we’re great talents and our Uncle Roberts think that we will go to the Olympics. But sometimes it’s a lot harder to think such nice thoughts about ourselves. If you find that believing in yourself is a challenge. It is time you build a positive self-image and learn to love yourself.
Self-image is your own mind’s picture of yourself. This image includes the way you look, the way you act, the way you talk and the way you think. Interestingly, our self-images are often quite different from the images others hold about us. Unfortunately, most of these images are more negative than they should be. Thus changing the way you think about yourself is the key to changing your self-image and your whole world.
The best way to defeat a passive self-image is to step back and decide to stress your successes. That is, make a list if you need to, and write down all of the great things you do every day. Don’t allow doubts to occur in it.
It very well might be that you are experiencing a negative self-image because you can’t move past one flaw or weakness that you see about yourself. Well, roll up your sleeves and make a change of it as your primary task. If you think you’re silly because you aren’t good at math, find a tutor. If you think you’re weak because you can’t run a mile, get to the track and practice. If you think you’re dull because you don’t wear the latest trends, buy a few new clothes. But remember, just because you think it doesn’t mean it’s true.
The best way to get rid of a negative self-image is to realize that your image is far from objective, and to actively convince yourself of your positive qualities. Changing the way you think and working on those you need to improve will go a long way towards promoting a positive self-image. When you can pat（拍）yourself on the back, you’ll know you’re well on your way. Good luck!

“If music is the medicine of the soul(灵魂), let it play on,” said a famous person. I think he said so because probably he got some help from music. Music has some strange abilities. Medical scientists have found that a person that feels stressed can actually listen to some kind of music and become well.
The researchers said that since stress comes as a result of life events such as starting a new family, starting a new business, and starting a new job, one can actually listen to good music and feel good because good music touches the human mind in a positive way. Music helps you to forget the life events that make you worried and remember the important events that once happened in your life.
Depression(抑郁) is a disease cause by stress, smoking, social problems and so on. Depression is also caused by problems such as failure in business. Depression may bring us weakness, headache, and loss of concentration. Good music makes one remember happy moments or good days. If you play music about love, it makes you feel like falling in love again though you may have had several upset experiences. And such good feeling make you healthy.
Anxiety(焦虑) is another health problem that can be controlled by music. Anxiety is a side effect of some major health problems such as cancer of the liver and cancer of the breast. Good music makes you feel relaxed and removes the pains from these diseases and you feel all right.
Good music can send you to sleep. And you need to know that sleep puts your body in a healthy condition. Sleep takes away the effects of stress, depression and anxiety from a person.

The average American child spends three to five hours a day watching TV. In 1961, the average child began to watch television at age three; however, today it is nine months. Yet, most parents think that television has bad influence on their children. For example, in the early 1970s, my parents believed that my bad eyesight was the result of sitting too close to the screen, and they therefore made my stay at least six feet from it. Today, most people have no such worry, but many new ridiculous (荒谬的) sayings have appeared:
*TV makes kids stupid. Many children watch more educational programs when they are pre-schoolers. When they grow up, they can read more books and have much better ideas to solve difficult problems than other children.
*TV makes kids violent. The real story is not so simple. Hundreds of studies show that watching violence on TV makes children more aggressive (好斗的). But a study of over 5,000 children also finds that some positive programs make children kinder. The problem is that kids are increasingly watching shows with violence instead of those suitable for their age.
*Sitting around watching TV makes kids overweight. An experiment finds that when children watch less television, they do lose extra weight; however, reducing their television time does not make them more active. The real problem lies in snacking (吃零食). A widespread habit for kids, and junk-food advertisements.
*TV helps kids get to sleep. The opposite is true. The more television children watch, the more likely they are to have irregular sleep and nap(小睡) patterns. Allowing kids to watch television is part of the problem, not the solution.
Which one is the advantage of educational TV programs?

A．They will make children solve difficult problems better than others.

B．they will improve children’s ability to get along with others.

C．They are likely to make children more aggressive.

D．They will make sure of children’s success in the future.

Why are children spending much time watching TV likely to be fat?

A．Watching TV makes children lazy and inactive.

B．Children are attracted by the food advertisement on TV.

C．Watching TV doesn’t burn up as much fat as doing sports.

D．Children like to snack while watching TV.

What influence does watching TV have on a child’s sleep?

A．Children are likely to sleep deeper after watching TV.

B．Children’s sleep time will be greatly reduced.

C．It will make children form a bad habit of sleeping.

D．It will make children sleep easier.

What is the purpose of this text?

A．To increase people’s knowledge of watching TV.

B．To warn parents of the disadvantages of watching TV.

C．To explain the bad influences that watching TV has on children.

D．To correct parents’ wrong ideas of television’s effect on children.
