Have you ever wondered why birds sing? Maybe you thought that they were just happy. After all, you probably sing 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 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 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 of their own. Most of it has to do with attracting mates and setting up territories.Some scientists believe that most of the time bird’s singing is actually _____________.
A.an expression of happiness | B.a way of warning |
C.an expression of anger | D.a way of greeting |
What does the underlined word“territory”mean?
A.A place where families of other species are not accepted. |
B.A place where a bird may shout at the top of its voice. |
C.An area for which birds fight a against each other. |
D.An area which a bird considers to be its own. |
Why do birds keep on singing at nesting season?
A.Because they want to invite more friends. |
B.Because their singing helps frighten outsiders away. |
C.Because they want to find outsiders around. |
D.Because they want to express their happiness. |
Macao(澳门) is only forty miles from Hong Kong and it is easy to reach. You can get there by sea. It is an interesting place and it had a long history. Macao is part of China and most people living there are Chinese.
The first Europeans to go to Macao came from Portugal(葡萄牙). More than four hundred years ago the Portuguese went there to trade with China. Some settled and made their homes there. They built strong forts(堡垒,炮台) to guard the city and the harbor. They also built churches, schools, hospitals and other places. Slowly the city grew. People from many countries came to live and work in Macao.
Today many people visit Macao. Some only go there to watch dog-racing or motor-racing or to gamble(赌博) with their money. But Macao is a quiet and peaceful place. It is pleasant just to walk around and look at old buildings and forts. You feel you are back in the old days. Of course, some of the buildings are now in ruins. The Church of St. Paul has only the front wall with many steps leading up to it. But it is still interesting to see.
When you are hot and tired, there are small cool gardens to rest in. when you are hungry, there are good restaurants with many kinds of food. Nearby there are some islands, which are also nice and are easy to get to. There is certainly a lot to do in Macao. Macao is easy to get to because_________.

Because earthquakes happen without warning, it’s important to take measures now to prepare. Because you don’t know where you will be when an earthquake happens, prepare some supplies for your home, workplace, and car.
1. Water
A person needs at least 1/2 gallon(加仑) of water daily just for drinking. Store at least 1 gallon of water per person per day and be prepared for a 72-hour period. It is suggested that you buy bottled water. Keep bottled water in its original container and do not open it until you need to use it. Also, do check the “use by” date.
2. Food
It’s always a practical idea to keep a supply of non-perishable(不易腐烂的) food on hand. Have an enough supply of canned food, powdered milk, dried fruits, non-salted nuts and canned juices for at least 72 hours.
3. Torch(手电筒) and spare batteries (电池)
Keep a torch beside your bed, at your place of work, and in your car. Do not use matches or candles after an earthquake until you are sure that no gas leaks(泄露).Prepare a battery-powered radio and spare batteries. Most telephones will be out of order, so radios will be your best source of information.
4. Clothes
If you live in a cold place, you must think about warmth. You might not have heat after an earthquake. Think about your clothing and bedding supplies.Why should people prepare themselves for an earthquake?
A.Because earthquakes can be known before they happen. |
B.Because earthquakes take place without warning. |

How to eat healthfully can be especially complex for working women who often have neither the desire nor the time to cook for themselves (or for anyone else ).Registered dietitian Barbara Morrissey suggests that a few simple rules can help.
“Go for nutrient-dense foods,”she suggests,“foods that contain a multiple of nutrients. For example,select whole wheat bread as a breakfast food,rather than coffee cake. Or drink orange juice rather than orange drink,which contains only a small percentage of real juice—the rest is largely colored sugar water. You just can't compare the value of these foods, the nutrient-dense ones are so superior,”she emphasizes.
Morrissey believes that variety is not only the spice of life,it's the foundation of a healthful diet. Diets which are based on one or two foods are not only almost impossible to keep up the strength,they can be very harmful, she says, because nutrients aren't supplied in enough amounts or balance.
According to Morrissey,trying to find a diet that can cure your illnesses,or make you superwoman is a fruitless search.“ As women,many of us are too concerned with staying thin,”she says,and “we believe that vitamins are some kind of magic cure to replace food.”
“We need carbohydrates,protein and fat-they are like the wood in the fireplace. The vitamins and minerals are like the match,the spark,for the fuel,”she explains.“ We need them all,but in a very different proportions(部分). And if the fuel isn't there,the spark is useless.”From the first paragraph we know that working women________.
A.think cooking is especially complicated |
B.do not share the same views with registered dietitians |
C.are busy and not interested in cooking |
D.are likely to eat healthfully |
Orange juice is different from orange drink because________.
A.it contains only a small percentage of real juice |
B.it is natural,nutritious and prepared from real oranges |
C.it is largely orange-colored sugar water |
D.it produces nothing but calories |
In Paragraph 4,“a fruitless search” means “____”.
A.an effort with no results |
B.a search for a diet without fruits |
C.a research on fruitless diet |
D.a diet serving as medicine |
Many women take it for granted,according to the passage that________.
A.a balanced diet can result in being fat |
B.staying thin and healthy are both possible |
C.lack of variety in diets leads to staying thin |
D.vitamins are some kind of substitutions(代替物)for food |
By saying “if the fuel isn't there,the spark is useless”,the author means “________”.
A.carbohydrates,protein and fat are enough to support a human life |
B.vitamins and minerals are almost of no value |
C.carbohydrates,protein and fat are as important as vitamins and minerals |
D.without carbohydrates,protein and fat,vitamins and minerals are of no use |

Two thieves came to a house to steal something. They dug a hole in the wall of the house.
