Water is very important to living things. Without water there can be no life on the earth. All animals and plants need water. Man also needs water. We need water to drink, to cook our food and to clean ourselves. Water is needed in offices, factories and schools. Water is needed everywhere.
There is water in seas, rivers and lakes. Water is found almost everywhere. Even in the desert part of the world, there is some water in the air. You can not see or feel it when it is a part of the air. The water in the seas, rivers and lakes is a liquid, the water in the air is a gas, and we call it water vapour (蒸气).
Clouds are made of water. They may be made of very small drops of water. They may also be made of snow crystals(结晶体). Snow crystals are very very small crystals of ice. Ice is frozen water. It is a solid. There can be snow and ice everywhere in winter.
Water may be a solid or a liquid or a gas. When it is a solid, it may be as hard as a stone. When it is a liquid, you can drink it. When it is a gas, you can not see or feel it.

Don't you just love ice skating every winter? I am sure, that since winter is approaching, your skates are set to come out, just waiting to be used. Impress your friends with your new trick on how to ice-skate backwards with the help of these tips. Skating backwards on ice is a bit difficult but once you master the basic, there' s nothing like it. Follow the steps given below and you will be able to skate backwards in no time.     

Stand Straight

The first thing that you need to do is, stand straight. If you feel that you are falling backwards, then just put your chin up and slightly bend your knees. Don't worry; this happens to all.

Confidence is What You Need

The most important step while learning how to skate backwards, is having enough confidence in yourself and in what you are doing. How can you achieve this? By practice. Just practice rolling backwards down a gentle slope every single day or just by pushing off from a wall or something of that sort. But before you do that, make sure that the place where you are practicing is free from any kind of debris(碎片)because otherwise, you could end up in the hospital due to some accident. While going backwards, just get used to the feeling of moving backwards. One of the important ice skating tips and techniques is that if you feel that you are losing your balance, then scissor (做剪式运动) your skates. Keep practicing this till you are confident about it.

Maintain Speed

Confident now? Great! Now the next step is to maintain your speed. While rolling in a straight line with one skate, with the other try sculling (滑浆), that is, keep pushing yourself backwards with an outwards stroke (滑动). Now bring the skate which you were using to scull, and then again, repeat the same process. Make sure that you put most of your weight on the skate which is moving straight and not the one with which you are sculling. Now, try the same thing using the other foot. Again keep doing this till you are confident enough.

Increase Your Speed Now

Once you are confident that you can scull with either foot, the next thing that you have to do is increase your speed. Try some of your own tricks now. Scull with either foot or with both at the same time.

Scull and Be Aware

While you keep one foot straight, keep sculling with the other. You can do that simultaneously with both feet. Concentrate on what you are doing but don't get so involved that you don't see where you are going. If you are not watching your back, you might just bang against something or someone.

1.According to the text, confidence comes from ________ .

A. constant exercise          B. strict coaches                  C. high speed             D. good techniques

A. c→a→d→b                     B. c→b→d→a            C. c→b→a→d   D. a→c→b→d

3. In the last paragraph the author mainly wants to express _________.

A. one must be brave to learn to ice-skate backwards           

B. skating and keeping cautious are both important

C. it’s difficult to concentrate when ice-skating backwards

D. it' s a common thing to hit someone when ice skating backwards

4.The purpose of the text is _______ .

A. to offer some advice on ice-skating backwards

B. to introduce the culture of ice-skating backwards

A new study shows one of the largest glaciers(冰川) in Greenland is becoming smaller and speeding to the sea faster than scientists expected. If it continues, Greenland itself could become much smaller during this century and global seas could rise as much as 3 feet.

The rates of change that we’re noticing are much higher than expected. If these rates continue, it is not likely that Greenland could shrink by several tens of percent this century. However, it’s not known how quickly this coastal response of the Greenland ice sheet melting will have an effect on the vast inland ice.

Greenland is the world’s largest island, covering area more than three times the size of Texas. Some 81 percent of it is covered by ice, and there are many glaciers. Glaciers are like slow-moving rivers of ice. Where a glacier meets the sea, its weight keeps it firmly resting on the bottom. A glacier’s front is the point where the water is deep enough that the glacier floats.

Since the 1970s, the front of Helheim stayed in the same place. Then it began melting rapidly, moving back 4.5 miles from 2001 through this past summer. It has also grown thinner, from top to bottom, by more than 130 feet since 2001. And over these past years, its trip to the sea has sped up from about 70 feet per day to nearly 110.

The melting is driven by a warmer climate. Temperatures in Greenland have risen more than five degrees Fahrenheit(华氏温度) in the last ten years. Since most of Greenland’s ice is on land, seas will rise as the ice melts. If all Greenland’s ice sheet melted, oceans would be 15-20 feet higher. Nobody expects that to happen any time soon.

1.What can we know about the glaciers according to the passage?

A.Glaciers only lie in Greenland.

B.Water in glaciers is more than sea water.

C.Glaciers sometimes float on the water.

D.Glaciers can increase the water level of lakes.

2.According to the passage, we know that Greenland ___________.

A.belongs to Canada

B.is the largest island in North America

C.is all covered with glaciers

D.is sinking under the sea level

3.Which of the following may be the result of the disappearing of Greenland glaciers?

A.The climate of the world will be warmer.

B.The glaciers in other areas will be bigger.

C.It will be easy for explorers to visit the island.

D.Some coastal cities may be under the sea.

Growing up, I always dreamed of being a professional figure skater. After years of hard work, I am living proof that dreams can come true.

When I was born, my parents immediately noticed something  36  and the doctor said I couldn't skate. I, however,  37  trying skating in an ice rink (溜冰场), where local skaters   38  perform ice shows. I started taking group skating lessons, and performing on ice came naturally, but I have always been  39  to speak in group settings. One thing I've never been afraid of is  40  , though. I get nervous, but never  41  . For me, skating has been about being my personal best  42  beating others on the ice. 1 progressed through various  43 rapidly and gave my first ice performance at seven. Soon I started winning local and regional competitions. That's  44  being on the ice has always been the one place where I can  45   express my own emotions. The ice is like home.

When I was nine years old I began training  46 . I would wake up at four o'clock in the morning six days a week and skate for five hours. Then I'd go to school. Since  47  has always been important in my family, I had no  48  but to find creative ways to fit in school studies throughout my  49  career.

After graduating from high school, I moved to Canada and set out to train full-time to give my dreams a chance at reality. In 1992 I went to compete in the Olympic Games.  50 , not my coach or even my family, ever talked to me about winning a gold medal. In fact, I wouldn't even  51  myself to think about it. I thought that would disturb me.  52 , I went with the attitude that I wanted to enjoy the Olympic spirit.  53  the expectation of all the people, I won the gold medal and words couldn't describe the overwhelming mixture of emotions I felt. Then I truly understood what  54  most in achieving a dream is nor to  55  it when you 1ace difficulties, but strive to make it come true.
