Have you ever wondered why birds sing? Maybe you thought that they were just happy. After all, you probably sing or whistle when you are happy.
Some scientists believe that birds do sing some of the time just because they are happy. However they sing most of the time for a very different reason. Their singing is actually a warning to other birds to stay out of their territory.
Do you know what a ‘territory’ is? A territory is an area that an animal, usually the male, claims (声称) as its own. Only he and his family are welcome there. No other families of the same species are welcome. Your yard and house are your territory where only your family and friends are welcome. If a stranger should enter your territory and threaten you, you might shout. Probably this would be enough to frighten him away.
If so, you have actually scared the stranger away without having to fight him. A bird does the same thing. But he expects an outsider almost any time, especially at nesting（筑巢）season. So he is screaming all the time, whether he can see an outsider or not. This screaming is what we call a bird’s song, and it is usually enough to keep an outsider away.
Birds sing loudest in the spring when they are trying to attract a mate and warn others not to enter the territory of theirs.
You can see that birds have a language all their own. Most of it has to do with attracting mates and setting up territories.

To learn an instrument(乐器) such as the violin or accordion（手风琴）takes years. The job opportunities for musicians are scarce and competition is fierce. Then why are more people than ever before paying a lot of good cash to get their children the best music teaching they can afford?
The secret lies in the influence of music on the whole person. It has been found that learning a musical instrument actually increases a person’s IQ over time. Different instruments and different trypes of music have varying effect, with classical music and the string（弦乐） family coming out on top, potentially increasing you IQ by up to 12 points!
When is a good time to start learning music? Experts have found that even the fetus（胎儿）can benefit from listening to classical music. Surround yourself and your family with good music from the first. The Suzuki Piano Method teaches children from the age of 3 years piano, with two lessons per week. From preschool, children can learn to read music and play from sheet music. Progress in learning your instrument is directly proportional（成比例的）to the amount of practicing.
Is there such a thing as an unmusical child? Shinichi Suzuki proposes that music is the native home language of all human beings and therefore nobody can be “unmusical”. Of course there are exceptional talents, compared to which others may seem to be slower learners.
Is there any benefit for adults in starting an instrument? Apart from the purely relaxing aspect, yes. Learning an instrument can earn even adults additional IQ points, and as an added benefit in improves your health by reducing your stress levels. Your social life may benefit too, if you are prepared to come out of your box and join occasions such as Ceilidhs (musical get-togethers) or arrange house concerts. It has been established that people who play instruments tend to be more emotionally balanced and more patient with themselves, others and life in general.
So go ahead, sign up for that amateur orchestra, dust off your old trombone（长号）or take your first real six-string down from the attic（阁楼）; get out there and play!Playing which of the following musical instruments can help increase a person’s IQ most?
| A．The piano | B．The violin | C．The trombone | D．The accordion |

Officials in the Midwestern U. S. town of Joplin, Missouri, say the death from Sundays’ big tornado reaches 116 and that search efforts continue for possible survivors trapped in rubble (碎石). Search and rescue teams are conducting their third sweep through the nearly 10 kilometer – long and one – kilometer wide area of destruction left by the tornado. They are working as quickly as possible while weather conditions remain relatively stable. More storms are forecast for the area.
Joplin Fire Chief Mitch Randles said there are areas with large piles of rubble that might hold survivors. “We are still finding individuals. We did rescue seven individuals from underneath rubble yesterday and, of course, we are also finding dead folks as well.” Said more folks and that is why we are doing these searches. We want to make every opportunity that we can to find everybody that is in the rubble and that has survived to this point.”
Randles said the current sweep involves a slower pace that previous searches and that he plans a fourth search, possibly on Wednesday, using specially trained dogs. “We are searching every structure that has been damaged or destroyed in a more in-depth manner, “he said.” I have dogs and dog handlers coming from all over the country do help us in that effort.”
Joplin City Manager Mark Rohr said the Red Cross and other volunteer organizations are helping people who were left homeless by the tornado and that the Federal Emergency Management Agency, or FEMA, is on hand to help. “Joplin is a great city. We have suffered a great loss, “said Rohr.” We will recover and we will recover strongly and we have a lot of help and a lot of volunteers to make that easier.”
The tornado that struck Joplin was classified by the Natioonal Weather Service as an F – 4, with winds of more than 300 kilometers per hour. It lasted only 20 minutes, but it killed more that 100 people, injured more than 400 others, and destroyed or heavily damaged some 2,000 homes, businesses, churches and a hospital. Authorities have registered more than 1,700 calls about missing people and they hope to resolvemost of those cases soon, as victims are identified and survivors come forth and reunite with loved ones.
This was the worst tornado to strike the United States in 60 years. It was the latest in a wave of violent storms that have swept Midwestern and southern states in recent weeks, leaving more than 300 people dead an causing more than $2 billion dollars in damage.What kind of disaster (灾害)of this article is talking about?

Besides containing attractive flowers, trees and other plants that beautify the community, eco-friendly rain gardens are healthy for the environment and the people living and working nearby.
A rain garden （雨水花园）is not very different from a traditional garden. It is just a far more eco-friendly garden. Usually it is built lower than the ground. Rain gardens make smart use of rain and storm water by temporarily holding water from rain and storms and letting it soak（浸入）slowly into the ground before it runs into streams or enters the public drinking water supply.
Thus, a rain garden keeps the water, allowing it to be used as needed by plants in the rain garden, rather than flowing immediately into nearby streams and going unused. The water will soak slowly into the ground within a day or two. This creates an advantage that the rain garden does not allow mosquitoes to breed. This is a simple, attractive, and eco-friendly “green” way to treat storm water.
What’s more, planting a rain garden helps reduce pollution and improve the environment. Without using expensive machinery and chemicals, rain gardens remove harmful chemicals in the rainwater and cut down on the amount of pollution reaching streams and rivers by up to 30%.
Native plants are recommended for rain gardens because they are more used to the locals climate, soil, and water conditions. They may attract local wildlife such as native birds. Water your rain garden immediately after planting and once a week, unless you have had at least an inch of rain during the week. Once the native plants establish the necessary root system, it will require little care.
Often, local governments and private businesses develop large rain gardens in their yards and in public parks as a way to improve the environment and solve flooding problems. However, you don’t need to be a professional environmental engineer to create a rain garden. As long as you’re eco-conscious homeowners, you can help the environment by building smaller rain gardens in your yards.Which of the following is NOT RIGHT for the function(功能) of rain gardens?

People use their mouths for many things. They eat, talk, shout and sing. They smile and they kiss. In the English language, there are many expressions using the word “mouth.”
For example, if you say bad things about a person, the person might protest and say “Do not bad mouth me.” Sometimes, people say something to a friend or family member that they later regret because it hurts that person’s feelings. Or they tell the person something they were not supposed to tell. The speaker might say: “I really put my foot in my mouth this time.” If this should happen, the speaker might feel down in the mouth. In other words, he might feel sad for saying the wrong thing.
Another situation is when someone falsely claims another person said something. The other person might protest: “I did not say that. Do not put words in my mouth.”
Some people have lots of money because they were born into a very rich family. There is an expression for this, too. You might say such a person, “was born with a silver spoon in his mouth.” This rich person is the opposite of a person who lives from hand to mouth. This person is very poor and only has enough money for the most important things in life, like food.
Parents might sometimes withhold sweet food from a child as a form of punishment for saying bad things. For example, if a child says things she should not say to her parents, she might be described as a mouthy child. The parents might even tell the child to stop mouthing off.

| A．I have run a long way | B．I have been a mouthy person |
| C．I have learned a lot | D．I have talked too much |
Prolonging human life has increased the size of the human population. Many people alive today would have died of childhood diseases if they had been born 100 years ago. Because more people live longer, there are more people around at any given time. In fact, it is a decrease in death rates, not an increase in birthrates, that has led to the population explosion.
Prolonging human life has also increased the dependency load. In all societies, people who are disabled or too young or too old to work are dependent on the rest of society to provide for them. In hunting and gathering cultures, old people who could not keep up might be left behind to die. In times of famine (饥荒), infants might be allowed to die because they could not survive if their parents starved, where as if the parents survived they could have another child. In most contemporary societies, people feel a moral obligation (责任) to keep people alive whether they can work or not. We have a great many people today who live past the age at which they want to work or are able to work; we also have rules which require people to retire at a certain age. Unless these people were able to save money for their retirement, somebody else must support them. In the United States many retired people live on social security checks which are so little that they must live in near poverty. Older people have more illnesses than young or middle-aged people; unless they have wealth or private or government insurance, they must often “go on welfare” if they have a serious illness.
When older people become senile (衰老的) or too weak and ill to care for themselves, they create grave problems for their families. In the past and in some traditional cultures, they would be cared for at home until they died. Today, with most members of a household working or in school, there is often no one at home who can care for a sick or weak person. To meet this need, a great many nursing homes and convalescent (疗养的) hospitals have been built. These are often profit making organizations, although some are sponsored by religious and other nonprofit groups. While a few of these institutions are good, most of them are simply “dumping (倒垃圾的) grounds” for the dying in which “care” is given by poorly paid, overworked, and under skilled personnel (员工).The author believes that the increased size of the human population results from _______.
| A．an increase in birthrates | B．the industrial development |
