Dogs are social animals and without proper training, they will behave like wild animals. They will soil your house, destroy your belongings, bark excessively, fight other dogs and even bite you. Nearly all behavior problems are perfectly normal dog activities that occur at the wrong time or place or are directed at the wrong thing. The key to preventing or treating behavior problems is learning to teach the dog to redirect its normal behavior to outlets that are acceptable in the domestic setting.
One of the best things you can do for your dog and yourself is to train its obedience. Obedience training doesn’t solve all behavior problems, but it is the foundation for solving just about any problem. Training opens up a line of communication between you and your dog. Effective communication is necessary to instruct your dog about what you want it to do.
Training is also an easy way to establish the social rank order. When your dog obeys a simple request of “come here, sit,” it is showing obedience and respect for you. It is not necessary to establish yourself as top dog or leader of the pack（群）by using extreme measure. You can teach your dog its subordinate（从属的）role by teaching it to show submission to you. Most dogs love performing tricks for you to
pleasantly accept that you are in charge.
Training should be fun and rewarding for you and your dog. It can enrich your relationship and make living together more enjoyable. A well-trained dog is more confident and can more safely be allowed a greater amount of freedom than an untrained animal.

There is an English saying, “Laughter is the best medicine.” Until recently, few people took the saying seriously. Now however, doctors have begun to look into laughter and the effects it has on the human body. They have found that laughter really can improve people’s health.
Tests were carried out to study the effects of laughter on the body. People watched funny films while doctors checked their heart, blood pressure, breathing and muscles. It was found that laughter has similar effects to physical exercise. It increases blood pressure, makes the heart beat quicker and makes people breathe deeper; it also works several groups of muscles in the face, the stomach, and even the feet. If laughter exercises the body, it must be beneficial.
Other tests have shown that laughter appears to be able to reduce the effect of pain on the body. In one experiment doctors produced pain in groups of students who listened to different radio programmes. The group that tolerated (忍耐) the pain for the longest time was the group which listened to a funny programme. The reason why laughter can reduce pain seems to be that it helps to produce a kind of chemical in the brain which diminishes both stress and pain.
As a result of these discoveries, some doctors in the United States now hold laughter clinics, in which they help to improve their patients’ condition by encouraging them to laugh. They have found that even if their patients do not really feel like laughing, making them smile is enough to produce beneficial effects similar to those caused by laughter.According to the passage, which of the following statements is WRONG?
| A．Laughter is good for health. |
| B．Laughter can make you become old quickly. |
| C．Laughter helps to reduce pain. |
| D．Laughter, just like physical exercise, is good for our body. |
The underlined word “diminishes” in the third paragraph means “ ”.
| A．delays | B．prevents | C．increases | D．reduces |
Why do doctors hold laughter clinics?
| A．Because they want to earn more money. |
| B．Because they think they will help the patients recover from illnesses. |
| C．Because they want to improve their patients’ health. |
| D．Because they want their patients to laugh more. |
According to the author, we should __________ in our life.
| A．laugh as much as possible |
| B．watch more funny films |
| C．smile all the time |
| D．spend time in the laughter clinics |
What would be the best title for this passage?
| A．Both laughter and physical exercise are good for health. |
| B．Laughter clinics can help patients improve their condition. |
| C．Laughter can reduce the effect of pain. |
| D．Laughter is the best medicine. |
Most of the flowers in nature are red, orange and yellow. If we have seen a black flower, it’s a chance in million. People have made a census ( 普查 ) to colors of more than four thousand kinds of flowers and discovered that only eight of them are black. As we know, sunlight is formed by seven different colored lights. The wave length of each light is different, so the quantity of heat in each light is also different. Flowers, especially their petals ( 花瓣 ) , are easy to be harmed by high temperature. Black flowers can take in all the light waves which cause the flowers to dry up in a high temperature. So black flowers can rarely survive sunlight. But red flowers, orange flowers and yellow flowers can protect themselves from sunlight by reflecting the red light, orange light and yellow light, each of which has a large quantity of heat.It is _________ to see a black flower.
| A．impossible | B．seldom | C．common | D．no chance |
The passage tells us that ________________.
| A．black flowers are so weak that it is difficult for them to grow up. |

| D．black flowers can take in the light of all the wave lengths which make them dry up because of high temperature. |
Which of the following ideas is NOT true?
| A．People have found that only a few kinds of flowers are black. |
| B．Flowers are easy to be harmed by very high temperature. |
| C．Red, orange and yellow flowers can also absorb the light of all wave lengths. |
| D．The black flowers cannot protect themselves from sunlight. |
Americans like to travel on their yearly holiday. Today, more and more travelers in the United States are spending nights at small house or inns(客栈)instead of hotels. They get a room for the night and the breakfast the next morning.
Rooms for the night in private(私人的)homes with breakfast have been popular with travelers in Europe for many years. In the past five to ten years, these bed-and-breakfast places have become popular in the United States. Many of these America’s bed-and-breakfast inns have only a few rooms; others are much larger. Some inns do not provide telephones or televisions in the rooms, others do.
Staying at a bed-and-breakfast inn is much different from staying at a hotel. Usually the cost is much less. Staying at an inn is almost like visiting someone’s home. The owners are glad to tell about the areas and the interesting places to visit. Many vacationers say that they enjoy the chance to meet local families.Americans take a holiday trip _________.

One night about nine o’clock, Dr. Eyck, a surgeon, had a phone call from Dr. Haydon at the hospital in Clens Falls. The surgeon was asked to go there at once to operate on a very sick boy who shot himself while playing with a gun.
The doctor was soon on his way to Clens Falls. It was 60 miles away. And it was snowing heavily in the city. The surgeon thought he could get there before 12 o’clock.
A few minutes later, the doctor was stopped by a man in an old black coat. Gun in hand, the man ordered the doctor to get out. Then the man drove the car down the road, leaving the doctor in the falling snow.
It was after 2 o’clock in the morning when the doctor arrived at the hospital in Clens Falls. Dr. Haydon told him that the boy had died an hour before.

Money spent on advertising is money spent as well as any I know of. It selves directly to bring about a rapid sale of goods at reasonable prices, so setting up a firm home market and so making it possible to provide for export at good prices. By drawing attention to new ideas it helps greatly to raise standards of living. By helping to increase demand it causes an increased need for labor, and is therefore a nice way to fight unemployment. It lowers the costs of many services: without advertisements your daily newspaper would cost four times as much, the price of your television program would need to be doubled, and travel by bus or subway would cost more.
And perhaps most important of all, advertising provides a promise of reasonable value in the products and services you buy. Besides the fact that twenty-seven Acts of Parliament govern the terms of advertising, no regular advertiser dare promote a product that fails to live up to the promise of his advertisements. He might fool some people for a little while through misleading advertising. He will not do so for long, for the public has the good sense not to buy the poor article more than once. If you see an article frequently advertised, it is the proof I know that the article does what is promised for it, and that it has good value.
Advertising does more for the good of the public than any other force I can think of.
There is one more point I feel I ought to touch on. Recently I heard a well-known television person declare that he was against advertising because it persuades rather than informs. He was telling us the real difference. Of course advertising tries to persuade.
If its message were nothing but information, that would be difficult to get more people to buy, for even a detail such as the choice of the color of a shirt is a bit persuasive-advertising would be so boring that no one would pay any attention. But perhaps that is what the well-known television person wants.By the first sentence of the passage the writer means that .
| A．he is fairly familiar with the cost of advertising |
| B．everybody knows well that advertising is a waste of money |
| C．advertising costs more money than everything else |
| D．money spent on advertising is worth while |
In the passage, which of the following is NOT included in the advantages of advertising?
| A．Getting greater fame. | B．Providing more jobs. |
| C．Raising living standards. | D．Reducing newspaper cost. |
The author thinks that the well-known TV person is .
| A．quite right in passing his judgment on advertising |
| B．interested in nothing but the buyer’s attention |
| C．correct in telling the difference between persuasion and information |
| D．obviously unfair in his views on advertising |
In the author’ opinion .
| A．advertising can seldom bring material benefit to man by providing information |
| B．advertising informs people of new ideas rather than wins them over |
| C．there is nothing wrong with advertising in persuading the buyer |
| D．the buyer is not interested in getting information from an advertisement |
