Many people believe the glare（炫目的光）from snow causes snowblindness. Yet, with dark glasses or not, they find themselves suffering from headaches and watering eyes, and even snowblindness ,when exposed to several hours of“snow light”.

　　The United States army has now determined that glare from snow does not cause snowblindness in troops in a snow-covered country. Rather, a man’s eyes frequently find nothing to focus on（聚集）in a broad space of snow-covered without-grass land. So his gaze continually moves and jumps back and forth over the entire landscape in search of something to look at. Finding something, hour after hour, the eyes never stop searching and the eyeballs become tired and the eye muscles ache. Nature makes up for this discomfort by producing more and more fluid（流体）which covers the eyeball. The fluid covers the eyeball in increasing quantity until it makes eyes difficult to see dearly, and the result is total, even though for a short time, snowblindness.

　　Experiments led the Army to a simple method of overcoming this problem. Scouts（侦察兵）ahead of the troops are trained to shake snow from evergreen bushes, creating a dotted line as they cross completely snow-covered landscape. Even the scouts themselves throw lightweight, dark-colored objects ahead on which they can focus too. The men following can then see something. Their gaze is arrested. Their eyes focus on a bush and having found something to see, stop searching the snow-blanketed landscape. By focusing their attention on one object at a time, the men can cross the snow without becoming hopelessly snowblind or lost. In this way the problem of crossing a continuous white land is overcome.

To prevent snowblindness caused by the strong light from snow, wearing glasses or not _____.

　　A. depends on whether the snow is white enough    　B. makes no difference

　　C. makes much difference        　　            D. depends on whether the snow is thick

When the eyes are tired, tears flow out ______.

　　A. to clear the vision                             B. to make the eyes stop searching

　　C. to make the vision unclear                      D. to produce more and more liquid

Snowblindness can be avoided ________.

　　A. by moving one’s gaze back and forth

　　B. by walking ahead and keeping looking around

　　C. by making up for the discomfort of one’s eyes

　　D. by providing the eyes with something to focus on

Number　 sense is not the ability to count. It is the ability to recognize a 　 1　 in number. Human beings are born with this ability. 2 ，experiments show that many animals are, too. For example, many birds have good number sense. If a nest has four eggs and you remove one, the bird will not　 3 . However, if you remove two, the bird 4 leaves. This means that the bird knows the 　5　 between two and three.

Another interesting experiment showed a bird's 6 number sense. A man was trying to take a photo of a crow(乌鸦)that had a nest in a tower, but the crow always left when she saw him coming. The bird did not 7 until the man left the tower. The man had an 8 .He took another man with him to the tower. One man left and the other stayed, but they did not 9 the bird. The crow stayed away until the second man left, too. The experiment was　 10 with three men and then with four men. But the crow did not return to the nest until all the men were 11 .It was not until five men went into the tower and only four left that they were 12 able to fool the crow.

How good is a human's number sense? It's not very good. For example, babies about fourteen months old almost always notice if something is taken away from a 　13 group. But when the number goes beyond three or four, the children are 14　 fooled.

It seems that number sense is something we have in common with many animals in this world, and that our human 15 is not much better than a crow's.

阅读下列短文，从每题所给A、B、C和D项中，选出最佳选项，并在答题卡上将该项涂黑。

Advertising in America offers some great advantages to consumers. For example, in order to keep prices low through mass production, companies must have a mass market for their products. Mass advertising creates mass markets. Producers cannot afford to develop new products, put them on the market and wait for customers to discover them. This would take too long. Demand for some products must be created. This is done through advertising.

　　But advertising sometimes makes it difficult for consumers to make wise decisions. The fact is that when people are constantly flooded with messages through the mass media persuading them to buy particular products, many respond by buying them.

　　Advertising is designed to influence an individual to buy a product. Sellers often study human behavior to discover what will convince consumers to buy a certain item. This reason for buying is called a buying motive.

　　Buying motives are usually broken down into two categories: rational and emotional. Rational buying motives include the desire to save money, the desire for comfort, or the desire for good workmanship. Emotional buying motives include buying out of fear, wanting to be liked, and wanting to have something better than your friends have.

　　Emotional appeals are found in most consumer advertising today. Certain cars promise to make the driver feel "younger" and " freer". Shoes promise to make the buyer's whole life "springier". Life insurance policies promise to take the "care out of living".

　　Most consumers believe that they are not easily influenced by emotional appeals. However, corporations that sell consumer products obviously think differently. They spend many millions of dollars every day on radio, television, newspaper and magazine ads that use these appeals.　　

1. It can be inferred from the passage that one of the advantages of advertising for consumers is that ________.

A. it can create a big demand for consumer goods

B. the mass market created by it leads to low prices

　C. producers can introduce new products to consumers

　D. it helps consumers discover new products

2. Consumers sometimes find it difficult to make a sensible decision when buying a particular product     because __________ .

　A. many advertisements are too difficult for them to understand

　B. they are afraid to be taken in by dishonest advertisements

　C. mass advertising offers them a range of good and cheap products

　D. they are confused by the quantity of advertisements promoting it

3. According to the passage, a toothpaste ad promising that people who use the product will make a lot of friends is an example of an ad that appeals to __________ .

　A. rational buying motives                              B. the consumer's commonsense

　C. emotional buying motives                         　D. the desire for a good product

4. The reason why companies spend enormous amounts of money on advertising is that ________ .

　A. they believe people can be influenced to buy a certain produce

B. it takes a lot of advertising to convince people to buy a certain product

　C. most consumers are not easily influenced by emotional appeals

　D. advertising based on emotional appeals are very effective

5. The best title for this passage would be ________ .

　A. Advertising can create demand                  　B. The advantages of advertising

　C. What effective advertising can do              　D. The role of advertising in selling products

       Most musicians agree that the best violins were first made in Italy．They were made in Cremona, Italy, about 200 years ago．These violins sound better than any others．They even sound better than violins made today．Violin makers and scientists try to make instruments like the old Italian violins．But they aren’t the same．Musicians still prefer the old ones．No one really knows why these old Italian violins are so special, but many people think they have an answer．

Some people think it is the age of the violins．They say that today’s violins will also sound wonderful someday．But there is a problem here．Not all old violins sound wonderful．Only those from Cremona are special．So age cannot be the answer．There must be something different about Cremona or those Italian violin makers．

Other people think the secret to those violins is the wood．The wood of the violin is very important．It must be from certain kinds of trees．It must not be too young or too old．Perhaps the violin makers of Cremons knew something special about wood for violins．

But the kind of wood may not be so important．It may be more important to cut the wood in a special way．Wood for a violin must be cut very carefully．It has to be the right size and shape．The smallest difference will change the sound of the violin．Musicians sometimes think that this was the secret of the Italians．Maybe they understood more than we do about how to cut the wood．

Size and shape may not be the answer either．Scientists measured these old violins very carefully．They can make new ones that are exactly the same size and shape．But the new violins still do not sound as good as the old one．Some scientists think the secret may be the varnish, which covers the wood of the violin and makes it look shiny．It also helps the sound of the instrument．No one knows what the Italian violin makers used in their varnish．So no one can make the same varnish today．

There may never be other violins like the violins of Cremona．Their secret may be lost forever．Young musicians today hope this is not true．They need fine violins．But there aren’t very many of the old violins left．Also, the old violins are very expensive．Recently, a famous old Italian violin was sold for about US $ 300,000!

This passage is about _______．

　   A．making violins 　　　　　            B．musical   instruments

　   C．scientific ideas 　　　　              D．the old Italian violins

The best violins _______．

       A．are made with modern techniques 　    B．were lost   many years ago

       C．were made in Italy 200 years ago       D．were made by scientists．

Some people think that modem violins ______．

       A．will sound better in the future 　   B．will sound worse in the future

       C．sound wonderful naturally          D．will never be as old as those from Cremona

Violins made today _______．

　   A．look the same as the old ones

　   B．sound the same as the old ones

　   C．are better than the old ones　

       D．have the same varnish as the old ones

Hey! It's going to be Mother's day again. Have you planned something good for your Mama? If not, try even one of these tips.

Make Your Mama Proud

　　What special talents do you have? Maybe this is the right time to show it to her. She would be very proud and surprised if she'd realized that you have something that she doesn't expect.

　　What's Her Favorite?

　　Most teens don't know what their mama's favorite. You do? Then, what are you waiting for ? Buy her some of her favorite stuff and put a little twist on it. Make it more special.

　　The best time to give her that is while she is sleeping at night. Put it on the drawer next to her so that when she wakes up she'll be surprised to see it. And, maybe, a little tear may fall down from her cheeks.

　　The Memories

　　Our mothers have special memories in mind. Those are the times that they gave birth to their healthy baby. How about you? What's your best moment with her? Maybe you can tell her about the time she got mad at you because you did something that you thought is right but since that day forward you realized your mistakes. Or, you can tell her how happy you are when she was there during your painful days in your life.

　　Be Her

　　What does she look like if she is so exhausted and angry and tired? What does she do for your family? This is the right time to show her the things that she usually does at home. Try to imitate her voice when she is angry. Make your face as if you are her when she is mad.

　　Treat a Queen

　　Your house is a palace with a king and queen (it doesn't matter if you're rich or poor). Our mother is the real queen in our life and in our family though her duties make her look like she is not. Give the lady a day off by being a servant to her.

　　Make-Over Beauty

　　Because of stress and the problems that she is facing right now, especially in the family, she doesn't look great any more. Admit it! Most mothers are not into trends anymore because their focusing on us.

　　Perhaps you could take some of your savings to treat her in a salon or the department store. Then, choose nice clothes that would make her look GLAMOROUS!

　　Have Some of Your Time

　　It's the cheapest but a meaningful way. Most of us are busy from our work, friends, boy/girl friends, school. We stay home late and after several hours, we go out again.

　　Have you ever had a meaningful time with your mother where you don't think or talk about problems and arguments? Have you ever told her how much you thank her from the life she gave to you, the time she took care of you, and for every suffering she'd felt for you? Have you ever told her that you love her?

Life is short. We don't know what will happen tomorrow nor today. Those three words can make her heart jump for joy, you know? Just tell her “I love you!” and it would make her smile so sweetly. Just try! We don't want to miss a thing, right?
