Skating backwards on ice is a bit difficult but once you master the basis, there’s nothing like it. Follow the steps given below and you will be able to skate backwards in no time.

1.

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.

2.

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.

3.

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．

4.

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．

5.

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．

A. Find Another to Practise with You

B. Increase Your Speed Now

C. Gain Your Courage

D. Stand Straight

E. Maintain Speed

F. Scull and Be Aware

G. Confidence is What You Need

Seeds on Ice

Close to the North Pole，remote and rocky Plateau Mountain in the Norwegian archipelago of

Svalbard seems an unlikely spot for any global effort to safeguard agriculture. In this cold and deserted environment，no grains，no gardens，no trees can grow. Yet at the end of a 130-meter-long tunnel cut out of solid stone is a room filled with humanity’s most precious treasure, the largest and most diverse seed collection—more than a half-billion seeds.

A quiet rescue mission is under way. With growing evidence that unchecked climate change-will seriously affect food production and threaten the diversity （多样性） of crops around the world，the Svalbard Global Seed Vault （地窖） represents a major step towards ensuring the preservation （贮藏） of hundreds of thousands of crop varieties. This is a seed collection, but more importantly, it is a collection of the traits found within the seeds：the genes that give one variety resistance to a particular pest and another variety tolerance for hot，dry weather.

Few people will ever see or come into contact with the contents of this vault. In sealed boxes，behind multiple locked doors，monitored by electronic security systems, enveloped in below—zero temperatures, and surrounded by tons of rock, hundreds of millions of seeds are protected in their mountain fortress. Frozen in such conditions inside the mountain, seeds of most major crops will remain viable for hundreds of years, or longer. Seeds of some are capable of retaining （保留） their ability to grow for thousands of years.

Everyone can look back now and say that the Seed Vault was a good and obvious idea, and that of course the Norwegian government should have approved and funded it. But back in 2004, when the Seed Vault was proposed, it was viewed as a crazy，impractical, and expensive idea.

We knew that nothing would provide a definite guarantee. But we were tired，fed up，and frankly scared of the steady, greater losses of crop diversity. The Seed Vault was built by optimists who wanted to do something to preserve options so that humanity and its crops might be better prepared for change. If it simply resupplied seed gene banks with samples those gene banks had lost, this would repay our efforts.

The Seed Vault is about hope and commitrnent - about what can be done if countries come together and work cooperatively to accomplish something significant，long-lasting，and worthy of who we are and wish to be.

1.According to the passage, the Seed Vault is ___________.

A. a tunnel where the collected seeds are displayed

B. a stone room that contains the seeds of endangered crops

C. a seed gene bank that stores diverse seeds for future agriculture

D. a lab where researchers study how to maintain the diversity of crops

2.The underlined word“viable”in Paragraph 3 probably means ________.

A. mature　　 B. clean

C. alive　　 D. valuable

3.Paragraph 3 mainly tells us __________.

A. how the seeds are preserved　　 B. where people keep the seeds

C. why the seeds are protected　　 D. what people do to study the seeds

4.We can know from the passage that _________.

A. the Seed Vault offers a solution to climate change

B. most countries took part in rescuing the seed varieties

C. the Seed Vault guarantees to prevent the loss of crop diversity

D. many people originally considered building the Seed Vault unwise

Our room was on the second floor but you could still hear the roar of the ocean and see the stars at night. I used to take long walks along the water. The food in town was wonderful and the people were very friendly. The area was very quiet and peaceful, and fairly deserted.

The last evening of our vacation, however, we all heard strange footsteps following closely behind us as we were walking up to our room in the holiday centre. We turned around and noticed a fairly young man moving very rapidly across the beach and getting closer to us. He was tall and wore a baseball cap. We couldn’t see his face and he was approaching us very rapidly. The man’s actions made my dad very nervous. Dad warned us that we’d better try to make it to our hotel room as quickly as possible. I didn’t like my dad’s voice; I could hear fear in it. It was late and we were all alone. We didn’t have any cell phones on us. I never saw Dad as worried as he was then and I knew that something was terribly wrong. The sense of fear started to overwhelm Mom and me. We had had such a good time in town. Now, the night was rapidly turning into a dangerous situation.

We could hear the man’s footsteps getting closer. Dad’s face was almost pale. The so-called intruder (侵入者) had moved nearer and nearer when all of a sudden, the nearby vending (自动贩卖) machine started going crazy and spitting out cans of soda! The noise actually scared the intruder and he ran out of sight. My parents were shaking, but we all turned around to see who had put money into the vending machine downstairs, and actually saved us, but no one was around at all. Not a soul.

It’s one vacation I will never forget.

1.Where did the author spend her vacation?

3.What helped them get out of the trouble?

Ben, at the age of 23 ,was the youngest man to ski solo to the North Pole. He dragged a 180-kilogramme sledge (雪橇) over 1,420 miles through the worst Arctic conditions. This year, Ben plans to ski solo from the Antarctic coast to the South Pole and back in the autumn, carrying all his supplies on his sledge.

Ben Saunders was fired after persuading the firm to support his disorganized first adventure. “Everything that could go wrong did go wrong. We didn’t get to the Pole, so we had no media interest. No one heard about it.”

“People said it was impossible for me to get to the Pole. I said, “No, I can get there,” and I did. Self-belief, I see it as being a bit like a muscle — it's my belief that the more you stretch yourself the stronger it gets. If you never do anything that's uncomfortable or risky then your self-belief gets weaker. So that's one of the lessons I’ve figured out along the way.

“My Antarctic adventure is just practicable and that's what is exciting to me. If I knew I could do it without too much bother, I wouldn’t be interested." Why? “Personally I'm attracted by the human performance element to it. Not that long ago, running a marathon was seen as the top point of human attempt, and now I wouldn’t be that surprised if my mum said she was going to run one."

People’s horizons are changing. “I'm not particularly gifted. I’ve just chosen this one goal to achieve and I’ve been working hard to realize it. And that’s the thing that attracts me: with enough training and enough determination, enough focus and preparation, how far can we go? And I don，t think I've found out yet.”

1.What do we know about Ben Saunders’ first adventure?

A. It was ruined by his company.

B. There was no press coverage.

C. It was well planned and organized.

D. He actually reached the North Pole.

2.According to Ben Saunders, if you want to stretch your self-belief, you should______ .

A. often test your confidence

B. try something adventurous

C. aim to reach the North Pole

D. always stretch your muscles

3.Ben Saunders was excited about his Antarctic adventure because_______  .

A. he liked running a marathon

B. he wanted to exercise his body

C. he knew it might be achievable

D. he was sure he could do it easily

4.What can we learn from the last paragraph?

A. We have to change our views about adventure.

B. We can never know our possibilities and energies.

C. We should have a reason for going on an adventure.

D. We have to be especially talented to have an adventure.

高二英语单项填空困难题查看答案及解析

３１ｓｔ　Ｏｃｔｏｂｅｒ　—— A team of British explorers has announced they are going to the North Pole to measure the ice cap’s thickness. The exploration will take ground-based readings (仪表的读数) of an ice formation which most scientists agree is shrinking at an alarming rate.

Explorer Pen Hadow’s three-member team will pull a sled-fixed radar device, which measures ice density every eight centimeters, 2,000 kilometers across the Arctic and will produce millions of readings.

They will leave in February, 2008 and will face temperatures of -50℃ on a journey that will take up to 120 days. They have been testing their equipment in Britain and Canada.

Hadow is excited about the prospects (前景), “For the first time we will be able to transmit video images — webcam film of the expedition — as it unfolds so people can track us, and the whole idea is to engage as many people as we can in what we’re doing.”

New fallen snow on top of the ice makes ground-based measurements more accurate than satellite data.

“It has been in the planning stage for a while,” said Hadow. “We spent the last two years developing impulse radar (冲击雷达), which normally is about 100 kilograms and hangs under an aircraft and so on. We’ve managed to get it down to about 4 kilograms. It’s the size of a briefcase and we are dragging it behind the sled as we go.”

　　The ice cap shrank enough in 2007 so that a pathway through the cap known as the Northwest Passage opened up during the melting of the Arctic summer.

Cambridge University’s Joao Rodrigues explains, “Thickness of the ice cap will determine how much solar radiation will be reflected and the heat exchange between the ocean and the atmosphere and it is thus a vital component (成分) of climate models.”

If warming trends continue, some experts predict that the Arctic Ocean could be ice-free during the summer within a few decades.

1.What would be the best title for the text?

A. Exploration to the North Pole.

B. Arctic ice cap shrinking.

C. Arctic ice survey announced.

D. Ground-based measurements of ice.

2.What is special about the exploration?

A. It will be broadcast live on the Internet.

B. Explorers will use a sled-fixed radar device.

C. Explorers will travel in extremely cold conditions.

D. Ground-based measurements are more accurate.

3.What is the purpose of the exploration?

A. To measure the ice cap’s thickness.

B. To study whether ice will disappear in the Arctic.

C. To make a film about the Arctic exploration.

D. To make people interested in what they are doing.

4.It can be inferred from the passage that ________.

A. ice in the Arctic will disappear in ten years

B. the exploration will last for half a year

C. Hadow spent two years developing a kind of radar, which is about 100 kilograms

D. if there is snow on ice, satellites can’t measure the ice thickness accurately enough

5.From the passage, we learn that ________.

A. the explorers will measure ice density every other centimeter

B. people will be able to follow the explorers and see what they are doing

C. people could go through the Northwest Passage in the 2007 Arctic summer

D. the equipment that Hadow’s team use will be tested in the United States
