Animals Can Sense Natural Disasters
Among the dead in South Asia’ s tsunami(海啸)were many tourists at Sri Lanka’ s national wildlife park at Yala. But very few of the park’s animals — elephants, buffaloes, monkeys and wild cats — appear to have died. There are theories that animals can sense natural disasters and run away to safety.
First, it’s possible that the animals may have heard the quake before the tsunami hit. The underwater burst produced sound waves known as infrasound(次声). Humans can’t hear infrasound, but many animals including dogs, elephants, tigers and pigeons can.
A second early warning sign the animals might have sensed is ground vibration(震动). The great quake would have produced vibrational waves known as Rayleigh waves. These vibrations move through the ground like waves moving on the surface of the ocean but faster. They travel at ten times the speed of sound. The Rayleigh waves would have reached Sri Lanka hours before the water hit. Mammals, birds, insects and spiders can sense Rayleigh waves. So the animals at Yala might have felt the Rayleigh waves and then run to higher ground.
But what about humans? While we can’t hear infrasound, we can feel it, although we don’t necessarily know we’re feeling it. We also experience Rayleigh waves by special sensors in our joints(关节), which exist just for that purpose. Sadly, it seems we don’t pay attention to the information when we get it. Maybe we screen it out because there’s so much going on before our eyes and in our ears.
Why did few animals at Yala die when the tsunamis that caused a huge number of human deaths hit?

A.Because human beings cannot hear the infrasonic sound.
B.Because the animals were staying at a higher place in the park.
C.Because the animals were able to run much faster than human beings.
D.Because the animals might have picked up the danger signals and ran away.

Which of the statements about “Rayleigh waves” is true?

A.Rayleigh waves can be felt both by animals and human beings.
B.Rayleigh waves, just like infrasonic sound, can only be felt by animals.
C.Rayleigh waves are vibrational waves that usually cause quakes or tsunamis.
D.Rayleigh waves move on the ocean surface at a speed ten times that of sound waves.

According to the passage, which of the statement is true?

A.We can’t feel the infrasound so we can’t be informed of the danger.
B.We ignore the information of tsunami’s coming even though we can also get it.
C.We were so busy on our minds that we feel neither infrasound nor Rayleigh waves.
D.We can feel Rayleigh waves and infrasound so we can escape the danger like animals.

Dear Carol,
I wear braces (牙箍) and I know I look just terrible in them. Is there anything I can do to improve my appearance until they come off?
Connie N.
Philadelphia, PA
Dear Connie,
Start by thinking about how good you are going to look when your braces come off. If you are negative about your appearance, people will pick that up right away about you. In the meantime there are several things that you can do to lift your spirits:
Change your hairstyle. Be sure to get a good cut so that the shape of your hair will be flattering to your face and also good for your type of hair (fine, thick, straight, curly, etc.) Choose a hairstyle that draws attention away from your face. Hair pulled back into a pony-tail or into a ball on top or slightly off-center can be attractive and practical for this purpose.
Keep skin clean. If you choose to wear makeup(化妆品), it should look natural. Blusher(腮红) and lip gloss(润唇膏) in light tones of peach or pink are best.
Be well-groomed(打扮). Neatness really counts. People see a total look about you before they ever become aware of your braces. And first impressions are lasting ones!

Many teenagers feel that the most important people in their lives are their friends. They believe that their family members, especially their parents, don’t know them as well as their friends do. In large families, it is often for brothers and sisters to fight with each other and then they can only go to their friends for advice. It is very important for teenagers to have one good friend or many friends. Even when they are not with their friends, they usually spend a lot of time talking among themselves on the phone. This communication is very important in children’s growing up, because friends can discuss something difficult to say to their family members.
However, parents often try to choose their children’s friends for them. Some parents may even stop their children from meeting their good friends. The question of “choice” is an interesting one. Have you ever thought of the following questions?
Who choose your friends?

We are often asked to make a speech in life. Most of us are afraid of it and don’t do a good job. Here are some simple steps to make your speech a successful one. First of all, find out everything you can about your subject and at the same time find out as much as you can about your audience. Who are they? What do they know about your subject? Put yourself in their shoes as you prepare your speech. Then try to arrange your material so that your speech is clear and easy to follow. Use as many examples as possible. Never forget your audience. Don’t talk over their heads or talk down to them. When you are giving your speech, speak slowly and clearly, look at your audience and pause for a few seconds from time to time to give your audience chances to think over what you’ve said.

Nearly all the tourists who come to southeast France make a tour to Monaco(摩纳哥), too. Lying near the French-Italian border, Monaco is not part of France, but a separate principality(公国), though it is surrounded by its greatest neighbour.
Monaco became a principality in the 16th century after being owned by a family member of a certain Italian king. The French and Italians, however, soon came to “protect” it one after another, until 1861, when it became its own master again.
Facing the blue Mediterranean(地中海), Monaco is mainly made up of two cities, Monaco, where the palace of the prince(王子) stands, and Monte Carlo(蒙特卡洛), which is a wonderful place for tourists. Every year, around 500,000 people from all parts of the world come to Monaco, nearly 25 times as much as its population.
Believe it or not, Monaco has no soldiers or policemen of its own. Law and order is kept by French police, and French stands for it in its foreign affairs, even the money used in Monaco is franc, too.
56. Monaco is ___________ .
A. another name for Monte Carlo B. mostly visited by French tourists
C. surrounded by France D. more related to Italy than to France

It was once thought that air pollution only affected the area immediately around large cities with factories or heavy automobile traffic. Today we know that although these are the areas with the worst air pollution, the problem is actually worldwide. On several occasions over the past ten years, a heavy cloud of air pollution has covered the entire eastern half of the United States and led to health warning even in rural areas away from any major concentration of big factories or automobile. In fact, the very climate of the entire earth may be affected by air pollution. Some scientist feel that the increasing concentration of carbon dioxide in the air resulting from the burning of coal and oil is creating a "green house" effect--holding in heat reflected from the earth and raising the world's average temperature. If this view is correct and the world's temperature is raised only a few degrees, much of the polar ice will disappear and cities, such as New York, Boston, Miami, and New Orleans will be under water.
Another view, less widely held, is that increasing particulate matter (颗粒物质) in the atmosphere is blocking sunlight and lowering the earth's temperature--a result that would be equally disastrous. A drop of just a few degrees could create something close to new ice age and would make agriculture difficult or impossible in many of our top farming areas. At present we do not know for sure that either of these conditions will happen (though one recent government report prepared by experts in this field concluded that the green house effect is very likely). Perhaps, if we are lucky enough, the two trends will offset each other and the world's temperature will stay about the same as it is now.
72. As far as the green house effect is concerned, the author_________.
A. shares the same view with the scientist
B. is not sure that it will happen
C. thinks it impossible because there is no strong evidence
D. thinks it will destroy the world soon
73. According to what we read in the passage, _________.
A. raising the world's temperature only a few degrees would do no harm to life on the earth
B. lowering the world's temperatures only a few degrees would lead many major farming areas to disaster
C. the temperature in the countryside will remain permanent in the years to come
D. the particulate matter in the atmosphere has lowered the world's average temperature
74. The word "offset" in the last sentence means_________.
A. strengthen B. worsen C. balance D. support
75. This passage is mainly about_________.
A. the pollution caused by human beingsB. the green house effect
C. the potential effect of air pollution D. the possibility of a new ice age
