Snow contains much less water than rain, but much of the water the world uses comes from snow. Melting snow provides water for rivers, electric power stations and agricultural crops. In the western United States, mountain snow provides up to seventy-five percent of all surface water supplies.
Snowfall helps to protect plants and some wild animals from winter weather. Fresh snow is made largely of air trapped among the snow crystals (晶体). Because the air has trouble moving, the movement of heat is limited. Snow also influences the movement of sound waves. The surface of the snow takes in, or absorbs, sound waves. As snow grows older or if there have been strong winds, it can become hard and flat. Then, the snow,s surface will help to send back sound waves.
Snow may be beautiful, but it can be deadly. It is responsible for the deaths of hundreds of people. Many people die in traffic accidents on roads covered with snow and ice or from being seriously stuck in the winter storm. Others die from heart attacks caused by too much physical activity out in the cold.
People may not be able to avoid living in areas where it snows often. However, they can avoid becoming victims of snowstorms. People should stop driving and stay at home until the storm has passed. People living in these areas should carry emergency supplies in their vehicle. These include food,emergency medical supplies,and extra clothing to stay warm and dry.

解析
试题分析:文章讲述了雪的作用,能帮助动植物过冬,是主要的水的来源,及讲到了如何来避免在暴风雪中成为受害者。
小题1:细节题。文章第一自然段Snow falls in the Earth’s extreme North and South throughout the year. However, the heaviest snowfalls have been reported in the mountains of other areas during winter.可知,南极或北极终年积雪,但是,最大的雪却经常发生在山区。可知,山区的雪量比南北极的大。
小题2:细节题。从第三自然段Because the air has trouble moving, the movement of heat is limited.可知雪能够保护动植物过冬,是因为它能够阻止热的散失。故选B。
小题3:细节题。从第二自然段及第三自然段People may not be able to avoid living in areas where it snows often. However, they can avoid becoming victims of snowstorms.可知,A,B,C选项只是某一方面,并不全面,D选项回答更为全面。使人们成为了暴风雪的受害者。
小题4:细节推断题。从文章最后一句话可知,人们应该常备一些急救的药物或温暖的衣服,所以接下来应该是讲在冬天的户外如何来防止心脏病的发生。故选C。
点评:本文文脉清晰,对雪的自然现象、雪的作用及如何避免受伤三方面进行了说明。把握好这条主线,文章细节题居多,题目设置也不难,只需仔细的将问题和文章进行对比即可得出正确的答案。
核心考点
试题【Snow falls in the Earth’s extreme North and South throughout the year. However, 】;主要考察你对题材分类等知识点的理解。[详细]
举一反三
Recite and repeat in conversation.
When you hear a person’s name, repeat it. Immediately say it to yourself several times without moving your lips. You could also repeat the name in a way that does not sound forced or artificial.
Ask the other person to recite and repeat.
You can let other people help you remember their names. After you’ve been introduced to someone, ask that person to spell the name mad pronounce it correctly for you. Most people will be pleased by the effort you’re making to learn their names.
Admit you don’t know.
Admitting that you can’t remember someone’s name can actually make people relaxed. Most of them will feel sympathy if you say. “I’m working to remember names better. Yours is right on the tip of my tongue. What is it again?”
Use connections.
Link each person yon meet with one thing you find interesting or unusual. For example, you could make a mental note: "Vicki Cheng -- tall, black hair." To reinforce your associations, write them on a small card as soon as possible.
Limit the number of new names you learn at one time.
When meeting a group of people, concentrate on remembering just two or three names. Free yourself from remembering every one. Few of the people in mass introductions expect you to remember their names. Another way is to limit yourself to learning just first names. Last names can come later.
Go early.
Consider going early to conferences, parties and classes. Sometimes just a few people show up on time. There’re fewer names for you to remember. And as more people arrive, you can hear them being introduced to others --- an automatic review for you.
小题1:How will most people feel when you try hard to remember their names?
A.They will be moved. |
B.They will be upset. |

B.tell him a white lie |
C.ask him for pity |
D.ask others to help you |
A.all their names |
B.a couple of names first |
C.just their last names |
D.as many names as possible |
A.Tips on an important social skill. |
B.Importance of attending parties. |
C.How to make use of social skills. |
D.How to recite and repeat names. |
FOCUS
Focus is making a repeat appearance on my list this year because I’m too much of a multitasker. The problem is that I have trouble finishing one thing with so many things calling me. When I was working as a writer, all my projects were handled via a schedule, I’m putting a fitness and housekeeping routine into my schedule.
HEALTH
I get so busy taking care of everyone else, and I forget to take care of myself and this has to change. My health suffers and my weight suffers. I have to get my health in check , not only for me but because I promised my 9-year-old son. I’ll make good food and lifestyle choices. I miss being thin, and it’s time to get it back.
CELEBRATE
What good is having it if I’m not taking time to enjoy it? I have a wonderful job, a happy family, and so much to be thankful for. So how come I spend all my time working? Last summer my family took our first vacation in four years, the best thing I’ve done for myself and my family in a long time. This year, I’m making sure to take time to enjoy life and celebrate its many blessings.
Do you have any words for 2013?

Swimming is one of those activities that can be learned early in life. Little children can learn to swim as soon as they walk. In fact, you need the same skills in walking as in swimming. However, I believe that five is the best age to learn. By five or six, a child knows fear of water, a very important thing to know. It’s wise to be afraid, to recognize true danger. Young ones understand that the water can sometimes be very dangerous.
To really benefit from swimming, every swimmer should learn ____________:butterfly, backstroke, breaststroke, and crawl. I feel that one of these—the breaststroke—is different from the others, since some young swimmers use this stroke naturally, without any training.
In swimming, there are certain rules every swimmer should follow:
(1) Never swim alone! No matter how good you are in the water, don’t risk drowning by swimming alone. If you swim by yourself, with no life guards or friends with you, you may get into trouble.
(2) Don’t go beyond your abilities. Most swimmers know enough not to swim too far from the bank or the beach. Showing off by doing dangerous tricks is no good. Swim safely and you will continue to swim and alive.
(3) Don’t smoke. Swimming depends on a healthy body; good lungs are part of it.
(4) Work at any activity that builds muscles.

Something as simple as toothpaste contains at least three chemicals, if not more. It is the mixture of them and its chemical reaction that keeps your teeth clean. Other things you use every day are created by chemistry, such as hair products, shampoo and soap. Adding detergent (洗涤剂) to water involves chemistry. Without chemistry, we would never have known that we need soap to get the oil out of clothes or skin. Chemistry not only helps us make products for use, but it also helps us understand the world around us. Chemistry helps us understand what the ozone layer (臭氧层) is and how it protects us. Chemistry also gives us sunscreen to protect us from the sun. Thanks to chemistry, we know bleach (漂白剂) can’t be mixed with vinegar(醋), because it can produce poisonous gas.Without chemistry, we wouldn’t have fireworks displays on important days.
Chemistry plays a big role in food preparation. Cooking food causes it to go through a chemical change. That is why cooked food often tastes different from raw food. Baking is a great example of chemistry. Too much or too little of any ingredient(成分,尤指烹饪) makes a difference to the result of baking, for example, the dough (面团) won’t rise or the cake will be flat.
Chemistry isn’t something that just lives in a lab; it’s something that you meet hundreds of times every day. Knowing how chemistry works will give you a greater understanding of the science behind some of the simplest-looking things.
小题1:What’s the main idea of Paragraph 1?
A.Chemistry is easy to see around us. |
B.Sometimes chemistry is hard to see around us. |
C.How a science teacher does a big experiment. |
D.Few things in everyday life contain chemistry. |
A.cleaning teeth with toothpaste |
B.washing hair with hair products |
C.using soap to get the oil out of clothes |
D.washing your face with water |
A.harmful | B.healthy | C.fresh | D.pleasant |
A.One can’t find chemistry when cooking food. |
B.Chemistry plays an important part in food mak-ing. |
C.That dough rises is nothing to do with chemistry. |
D.A flat cake is the result of too many ingredients. |
A.Chemistry Around the House |
B.Chemistry in Science |
C.Chemistry for Dinner |
D.Chemistry in everyday life |
First the person must recognize that there is a problem.For example, Sam"s bicycle is broken, and he cannot ride it to class as he usually does.Sam must 39 that there is a problem with his bicycle.
Next the person must 40 the problem.Before Sam can repair his bicycle, he must know why it does not work.For example, he must 41 the parts that are wrong.
Now the person must look for 42 that will make the problem clearer and lead to 43 solutions.For example, suppose Sam decides that his bike does not work because there is something wrong with the brakes. 44 , he can look in his bicycle repair book and read about brakes, 45 his friends at the bike shop, or look at his brakes carefully.
After 46 the problem, the person should have 47 suggestions for a possible solution.Take Sam as an example 48 , his suggestions might be: tighten or loosen the brakes; buy new brakes and change the old ones.
In the end, one 49 seems to be the solution to the problem.Sometimes the 50 idea comes quite 51 because the thinker suddenly sees something new or sees something in a 52 way.Sam, for example, suddenly sees there is a piece of chewing gum(口香糖)stuck to a brake.He 53 hits on the solution to his problem: he must 54 the brake.
Finally the solution is 55 .Sam does it and finds his bicycle works perfectly.In short, he has solved the problem.
