Can you remember a morning when you’ve woken up to the ring of your alarm clock and wished you could stay in bed? You haven’t slept well, your hair is a mess. Worse, you can’t stop yawning. Yawning is universal to humans and many animals. Cats, dogs and fish yawn just like humans do! Yawning is an involuntary(无意识的,不自觉的) action during which you open your mouth and breathe deeply. The average duration of a yawn is about 6 seconds.
The purpose and cause of yawning are still a mystery. Scientists are not sure what causes a yawn. People yawn when they are tired or bored, but they also yawn when they aren’t. There are many ideas explaining why we yawn.
One idea is that yawning is a way for the body to become more alert by taking in more oxygen. A yawn increases the heart rate, forces carbon dioxide out of the lungs and blood stream, and brings oxygen to the brain. But one study showed that volunteers given a lot of oxygen did not yawn any less than before, while those given a lot of carbon dioxide did not yawn more.
Another idea is that early humans used yawning as a form of communication. If one decided it was time to sleep, they would tell the others by yawning and they would do it in return to show they agreed.
A third explanation comes from psychology professor Gordon Gallup of University at Albany in New York. He said that as people yawn, they cool off their brains. “Brains are like computers.” he said. “They only operate efficiently and effectively when they’re cool. Many things connected to yawning, like being tired, make the brain hot, and yawning can reduce the heat.”
Scientists have sent people into space, and created terrible nuclear weapons, but there are lots of seemingly simple things, such as why we yawn, or hiccup（打嗝）, that they can’t figure out. Next time you are in class in the morning, let out a big yawn and watch to see how many of your classmates yawn in response!

Every family with kids has seen its share of arguments, shouting and complaining. It turns out that all those conflicts serve an important purpose in the development of children . Saying “no” followed by a bad temper, just may be an unavoidable part of growing up. And that’s a good thing. These are the first steps toward independence. Even young children have to challenge their parents sometimes. Studies have shown the following:
·Although stressful, conflicts are beneficial for children.
·Learning to manage conflicts is necessary for a child’s development.
·Conflicts during the preschool years occur because children desire more attention than parents can or should give.
If you understand why conflicts occur, it can minimize the conflicts between you and your children. Conflict is a child’s attempt to develop a sense of self and how he or she learns to express his or her needs and ideas. Parents develop and drive this independence by putting children to the outside world both formally and informally.
Conflicts can grow out of a difference of opinion or might just be a way to blow off steam(发脾气). In rare situations, constant conflicts between parents and children can indicate a deeper emotional problem. Consult your doctor if this seems to be your situation.
It’s important to offer your child choices, which should be determined by age and developmental level. The more responsible a child is, the more choices he or she gets in reward. You can threaten your child with punishment, but often offering a choice will better improve angry situations. Consequences and rewards should have some meaning to your child.
Often a child’s adverse(敌对的)reaction when he or she hears the word “no” can be avoided by giving the child an explanation as to why you have refused his or her request.

Animals can move from place to place, but plants cannot. When an animal is under attack, it can run away or fight back. Plants certainly cannot run away, and they lack teeth and claws. But plants can defend themselves by using both physical and chemical means.
Some plants have their own ways to keep animals away. For example, the leaves of the holly plant have sharp spines(刺) that discourage grass-eating animals. Holly leaves on lower branches have more spines than leaves on upper branches. This is because the lower leaves are easier for most animals to reach.
Some plants , such as the oak trees, have thick and hard leaves that are difficult for animals to eat. Some grasses may contain a sandy material; eating such grasses wears down the animal’s teeth.
Many plants also have chemical defenses. Some plants produce chemicals that taste bitter or cause an unpleasant reaction. Some plants may fight against an attack by increasing the production of these chemicals. When a caterpillar(毛虫)bites a tobacco leaf, the leaf produces a chemical messenger. This messenger sends to the roots the information to produce more nicotine. The higher levels of nicotine discourage the caterpillar.
Many plants depends on both physical and chemical defenses. A certain plant in China , for instance, has prickly(多刺的) leaves, and each prickle contains poisonous venom(毒液). A single experience with this kind of plant will teach an animal to stay away from it in the future.

LONDON: The Edinburgh Festival, the biggest arts festival of its kind in the world, got under way in the Scotland capital on Sunday with a concert that included Hector Berlionz's To Deum, under the direction of Christoph von Dohnanyi.

People who have lost the ability to understand or use words due to brain damage are called aphasics(失语症患者). Such patients can be extremely good at something else. From the changing expressions on speakers’ faces and the tones of their voices, they can tell lies from truths.
Doctors studying the human brain have given a number of examples of this amazing power of aphasics. Some have even compared this power to that of a dog with an ability to find out the drugs hidden in the baggage.
Recently, scientists carried out tests to see if all that was said about aphasics was true. They studied a mixed group of people. Some were normal; others were aphasics. It was proved that the aphasics were far ahead of the normal people in recognizing false speeches — in most cases, the normal people were fooled by words, but the aphasics were not.
Some years ago, Dr. Oliver Sacks wrote in his book about his experiences with aphasics. He mentioned a particular case in a hospital. Some aphasics were watching the president giving a speech on TV. Since the president had been an actor earlier, making a good speech was no problem for him. He was trying to put his feelings into every word of his speech.
But his way of speaking had the opposite effect on the patients. They didn’t seem to believe him. Instead, they burst into laughter. The aphasics knew that the president did not mean a word of what he was saying. He was lying!
Many doctors see aphasics as people who are not completely normal because they lack the ability to understand words. However, according to Dr. Sacks, they are more gifted than normal people. Normal people may get carried away by words. Aphasics seem to understand human expressions better, though they cannot understand words.

|
A．They can fool other people. |
|
B．They can find out the hidden drugs. |
|
C．They can tell whether people are lying. |
|
D．They can understand language better. |
2. How did the scientists study aphasics?
|
A．By asking them to watch TV together. |
|
B．By comparing them with normal people. |
|
C．By organizing them into acting groups. |
|
D．By giving them chances to speak on TV. |
3.What do we learn from this text?
|
A．People poor at one thing can be good at another. |
|
B．What one says reflects how one feels. |
|
C．Aphasics have richer feelings than others. |
|
D．Normal people often tell lies in their speeches. |
