Snowfall helps to protect plants and some wild animals from cold, winter weather. Fresh snow is made largely of air trapped among the snow crystals. Because the air has trouble moving, the movement of heat is greatly reduced.
Snow also is known to influence the movement of sound waves. When there is fresh snow on the ground, the surface of the snow takes in, or absorbs, sound waves. However, snow can become hard and flat as it becomes older or if there have been strong winds. Then the snow"s surface will help to send back sound waves. Under these conditions, sounds may seem clearer and travel farther.
Generally, the color of snow and ice appears white. This is because the light we see from the sun is white. Most natural materials take in some sunlight. This gives them their color. However, when light travels from air to snow, some light is sent back, or reflected. Snow crystals have many surfaces to reflect sunlight. Yet the snow does take in a little sunlight. It is this light that gives snow its white appearance.
Sometimes, snow or ice may appear to be blue. The blue light is the product of a long travel path through the snow or ice. In simple terms, think of snow or ice as a filter. A filter is designed to reject some substances, while permitting others to pass through. In the case of snow, all the light makes it through if the snow is only a centimeter thick. If it is a meter or more thick, however, blue light often can be seen.

试题分析:本文给我们介绍了我们常见的雪的作用,及雪为什么会成白色。这里提到的它的作用有三点,一是雪给我们提供水源。二是雪能够给野生动植物防寒。三是雪能影响声的传播。
小题1:这是细节理解题。根据前三自然段可知雪能提供水源,能给野生动物和植物防寒,能影响声的传播,故选C。
小题2:这是细节理解题。根据Fresh snow is made largely of air trapped among the snow crystals. Because the air has trouble moving, the movement of heat is greatly reduced.因为雪里有空气,阻止热的运动。故选B。
小题3:这是推理判断题。根据When there is fresh snow on the ground, the surface of the snow takes in, or absorbs, sound waves. However, snow can become hard and flat as it becomes older or if there have been strong winds. Then the snow"s surface will help to send back sound waves. Under these conditions, sounds may seem clearer and travel farther.因为新鲜的雪能够吸收声波,这就影响了声的速度,而硬的雪有利于声的传播,加快了声的速度。故选C。
小题4:这是细节理解题。根据Snow crystals have many surfaces to reflect sunlight. Yet the snow does take in a little sunlight. It is this light that gives snow its white appearance.雪的晶体有许多表面来反射阳光,雪就吸收了一些光,就是这种光让雪成白色。故选D。

The suit has been specially designed so that it can be cleaned under the showerhead. There is no need for soaking (浸泡),dry cleaning-or even soap.
The Japanese market has taken a liking to the “shower suit”,described as “revolutionary” by its owner Australian Wool Innovation (AWI),which is the research and marketing body that represents Australian wool-growers. Orders have been placed for 170,000 of the woolen suits.
The suit could be worn in the shower,although it was probably better to hang it on a clothes hanger and carry it instead,AWI corporate affairs spokesman Stephen Feighan said.“The idea is that you hang it up and then...you give it a spray (喷雾),and it’s dry the next morning,” Mr Feighan said.
A Japanese researcher working for AWI invented the suit by combining three technologies. The secret is the best lining (内衬),which allows the suit to dry quickly.The shower suit attracted busy corporate people,particularly those who often traveled or stayed up late,Mr Feighan said.The airline industry was also interested.
Mr Feighan confessed he had not worn one of the suits yet,or tried to wash it in the shower,because they cut to fit Japanese figures.AWI believes that the shower suit will spread from the Japanese market through Europe and India. Mr Feighan hoped the suit,made from local wool,would be available in Australia in 12 to 18 months’ time.

An effective leader makes others feel good about themselves, as well as the work they are doing. The leader has a vision(幻想)of what he or she wants to achieve, and can communicate that vision to others in a way that makes people want to be part of it. One thing a good leader typically does is to communicate the big picture, so that each employee can see how the particular role he or she plays makes a contribution to the final result.
Good leaders are positive and optimistic when they speak about the future. Their enthusiasm wins them plenty of supporters who help make their vision a reality.
Good leaders also understand that different people are motivated by different things. For employees motivated by a need for achievement, a leader explains how the task offers an opportunity to take on a challenge with an achievable goal. And employees are motivated by hearing how they will be part of a team of people working together.
Good leaders will introduce employees by name first, rather than job titles. They refer to employees as team members, companions, or colleagues, never as “servants”. Words have power, including the power to make people feel whether or not they are important to the success of an organization.
Good leaders believe that every team member matters and set up environments that make everyone feel important. It is no wonder they can attract the support they need to help them achieve their goals.

“I have changed a lot,” she told the Huffington Post. “In October, we had 30 kids at our house! We have hosted parties with lots of food and music.”
Last January, the Wall Street Journal published an excerpt (节选) from Chua’s book with the headline “Why Chinese Mothers Are Superior”. In the excerpt, Chua described how her daughters were never allowed to have sleepovers (在外过夜的儿童聚会), appear in school plays, or earn any grade lower than an A. Chua, an author and professor at Yale Law School, spent much of 2011 on the defensive. In fact, many of her interviews seemed to lend fuel to her critics’ fire.
Now, with the book out in paperback, she said, “I put passages in the book and used very harsh words that I regret. Everybody has those moments you wish you could take back.”
For those who still read Battle Hymn as an advice guide, Chua argues that so-called tiger parenting should be employed mainly during a child’s early years, ideally between the ages of 5 and 12. These “super-strict parenting tactics” are not meant for all ages. Remaining strict after middle school makes you a helicopter parent, according to Chua. And she is quick to point out how different that is from being a tiger mom.
“By the time kids get to high school, helicopter parents are hiring all these tutors, carrying their kids’ sports bags. I never checked older daughter Sophia’s papers because I knew she knew how to sit down and focus,” Chua said.
As for younger daughter Lulu, 15, the rebel for whom the book was written, Chua has really backed off. Instead of forcing Lulu to practise violin for hours a day—the source of their biggest fights, Chua “let her give that up”. “My compromise (妥协) is that I’m going to still be as strict academically, but in exchange she has a lot of social freedom. Lulu has had four sleepovers in the last two months!” Chua said. Chua predicts she’ll only get more easygoing with age.
小题1:What does the passage mainly tell us?
A.Tiger Mom has changed and wants to be soft. |
B.Tiger Mom persuaded readers to follow her example. |
C.How Battle Hymn of the Tiger Mother came out. |
D.How Tiger Mom became the worldwide spotlight. |
A.Tiger Mom became stricter with her children |
B.Tiger Mom was thought highly by the public |
C.Tiger Mom’s life and family were influenced |
D.Tiger Mom became wealthy and easygoing |
A.whether she could do well at school |
B.when she could have sleepovers |

Your short-term memory is best during the morning—in fact, about 15 percent more efficient than at any other time of day. So, students, take notice: when you are faced with a morning exam, it really does pay to review your notes right before the test is given.
However, long-term memory is different. Afternoon is the best time for learning materials that you want to recall days, weeks or months later. Politicians, business executives or others who must learn speeches would be smart to do their memorizing during that time of day. You should try to do most of your studying in the afternoon, rather than late at night. Many students believe they memorize better while burning the midnight oil because their short-term recall is better during the early hours of the morning than in the afternoon. But short-term memory won’t help them much several days later, when they face the exam.
By contrast, we tend to do best on tasks related to the process of knowing, understanding, and learning numbers during the morning hours.
What about sports? During afternoon and early evening, you’re able to react the quickest to an outside stimulus—like a baseball speeding toward you. Studies have also shown that late in the day, when your body temperature is peaking, you will consider PE easier and less tiring—whether it actually is or not. That means you are more likely to work harder during a late afternoon or early evening workout, and therefore benefit more from it.
In fact, all of your senses—taste, sight, hearing, touch and smell—may be at their keenest during late afternoon and early evening. That could be why dinner usually tastes better to us than breakfast.
While all of us follow the same general pattern of ups and downs, the exact timing varies from person to person. It all depends on how your “biological” day is structured. Each of us can increase our knowledge about our individual rhythms. Learn how to listen to the inner beats of your body; let them set the pace of your day. You will live a healthier and happier life.
小题1:What does the underlined “it really does pay” mean?
A.It will cost a lot. | B.It requires price. |
C.It is very painful. | D.It is worthwhile. |
A.in the afternoon | B.in the late evening |
C.in the early morning | D.right before the exam |
A.we eat more food at noon |
B.we feel most tired if we exercise in the evening |
C.it is a good choice to study math in the morning |
D.we feel most sleepy before noon |
A.What’s Your Best Time of the Day for Different Tasks |
B.How to Live a Healthier and Happier Life |
C.How to Study Efficiently |
