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 (聲稱) as its own. Only he and his family are welcome there. No other families of the same species are welcome. Your house is 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 frightened 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.
小題1:Some scientists believe that most of the time bird’s singing is actually ________.
A．a(chǎn)n expression of happinessB． a way of warning
C．a(chǎn)n expression of angerD． a way of greeting

小題3: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 their singing helps get rid of their fears.
小題4:How does the writer explain birds’ singing?
A．By comparing birds with human beings.
B．By reporting experiment results.
C．By describing birds’ daily life.
D．By telling a bird’s story.
小題5:What does the underline word “screaming” in paragraph 4 mean?

We can express our feelings and needs by using body language. Cats can do that too. The ways that cats use their tails to show their feelings and needs are interesting.
Unlike dogs, which generally wave their tails to express good feelings, cats use their tails to send a lot of signals. When a cat waves its tail strongly from side to side, it may be a sign for us to leave it alone, or we may get scrathed (抓傷). Throwing a little toy for the cat to play with can get it relaxed. When a cat holds its tail upwards with a slight move, it means the animal is very happy to see its owner.
We all like to cuddle (依偎) inside our bed, and cats do that thing, too. Much as little children like to wrap (用……纏繞) their arms around their Teddy Bears, cats like to wrap their own tails around their bodies to get a sense of safety while asleep. If we notice a cat sleeping in such a position, we should not break its peace.
Usually the tip of the cat’s tail doesn’t draw our attention. But its particular position may also show the cat’s feelings. For example, a cat holding the tip of its tail pointed downwards may try to say that it is not feeling comfortable. So at this point, the cat not only feels angry, but also unsafe. This may again be a sign for us not to upset the cat in any way.
In conclusion, cats use their tails in many different, sometimes funny ways to send us messages, and we can learn to know more.
小題1:According to the text, in which way are cats different from dogs?
A．Cats draw more attention from humans than dogs.
B．Cats are friendlier to humans than dogs.
C．Cats have more feelings than dogs.
D．Cats show more feelings with tails than dogs.
小題2:When a cat waves its tail strongly from side to side, it probably feels    .
A．safeB．sleepyC．a(chǎn)nxiousD．hungry
小題3:A cat wraps its tail around its body when sleeping to      .
A．get its tail well relaxedB．get a sense of safety
C．show friendship to its ownerD．warn strangers to keep off
小題4:What does the fourth paragraph mainly tell us?
A．A cat can use its tail tip to show its feelings.
B．We should pay attention to the tip of a cat’s tail.
C．Why a cat holds the tip of its tail pointed downwards
D．A cat has many ways to express its feelings

Here is some news of the future.
March 20, 2035
There was a lot of news around the life extension drugs that hit the market a decade ago. They didn't promise that you would like forever, but they gave you a chance to extend your life an extra five to ten years. Even though the life expectancy rate at birth has increased greatly, the life expectancy for seniors hasn't improved that much. Basically, you have a greater chance to become a senior, but you will not have a much longer lifespan, and this is where the anti-aging drugs intend to kick in. So, do the anti-aging drugs work? Well，it is too early to tell. But the sales so far are very good.
April 19, 2035
Of the total US population of 378 million, people over 65 years of age now make up 20% for the first time. The senior ratio of only 4.1% by year 1900, and 12.4% 30 years ago.
The number of people above 65 compared to those of what is considered working ages, between 15 and 64, is currently 33.7%. This is up from 18.5% since year 2005, which means that for every retired person there are now two workers, compared to four workers 30 years ago. The number of people above the age of 80 has grown to 23.8 million, making them 6.3% of the total population compared to 3.6% in 2005.
April 12, 2040

We use an average of 158 liters of water a day in Britain, for which we pay a bargain price of 28p a liter, but much of this is just cash down the drain, according to water companies.
Most are campaigning to cut the amount we use. And the frontline weapon in their campaign is the water meter (計(jì)量器). They want us all to have one and one company is seeking powers to make this compulsory.
The Government is anxious for us to use less water, too. Elliot Morley, the Environment Minister, says he is impressed by the savings when a meter is installed. In most homes, consumption drops by 20 percent.
He also thinks consumers get a good deal from meters. He said, “Most people would find that they would either be exactly the same or better off with water meters and it is a fairer way of paying for water.”
At present, only 25% of households have meters and most of those are in East Anglia. They are installed by water companies, and households then have about ￡43 added to each bill to cover the cost of installing and reading the meter.
Barrie Clarke, a spokesman for Water UK, said, “We want everyone to be more water wise—to think about the amount of water they use. But with our climate change and different weather patterns, over time it will make economic and environmental sense to think how we use water. This may mean meters.”
Mr. Clarke believes the easiest way to save water is to use less in the garden. In one hour, a sprinkler uses the same amount of water as the average family of four uses in a day—about 632 liters. He said that gardeners should water in the evening so that it dose not evaporate in the heat of the day and that every household should have a water butt to collect rainwater for use in the garden.
小題1:Which of the following is NOT the advantage of installing water meters?
A．Water consumption drops.
B．It’s fairer to pay for water.
C．They’re installed for free.
D．People are more water wise.
小題2:The passage implies that ________.
A．water meters are welcome by British people
B．people will be better off with water meters
C．everyone has become wiser to use water now
D．saving water is both good to economy and environment
小題3:How many liters of water does an average family of four use in a day after installing a meter in Britain?
A．a(chǎn)bout 126 litersB．a(chǎn)bout 158 liters
C．a(chǎn)bout 506 litersD．a(chǎn)bout 632 liters
小題4:The underlined word “evaporate” in the last paragraph means _________.
A．change into steam and disappears
B．a(chǎn)bsorb the heat of the day
C．sink into the soil
D．turn into ice
小題5:According to Mr. Clarke, some good ways to save water are as follows EXCEPT ________.
A．using less on the garden
B．using a sprinkler
C．watering in the evening
D．gathering rainfall for garden use

It’s a sure sign that summer is over and winter is on the way — leaves that were once deep green turn red, yellow and bright orange. It happens every autumn. But did you ever wonder why?
The leaves start changing color when the nights start getting longer and the temperature starts getting cooler. Some scientists think that as the number of daylight hours shrinks, the leaves stop making chlorophyll which makes plants green. The reason is that the process of making chlorophyll requires sunlight. But according to horticulture (園藝) educator Susan Rose from Colorado State University, it turns out leaves don’t really change color at all. “The fall colors are actually there all along,” she said. “But they are covered by the green chlorophyll. As the chlorophyll stops being produced, the other colors can shine through.”
The kind of color that the leaves are going to change to is determined by the plant’s genetic (基因的) background. In some places, the leaves start changing color in September — before autumn even officially begins. In other places, they don’t change until late October or even November. Some scientists say the leaves have been changing color later than usual in recent years. And they think global warming has something to do with that.
In one study, researchers found that the growing season in the Northern Hemisphere was nearly a week longer, on average, in 2008 than it was in 1982. And a professor from Harvard University found that the leaves, west of Boston, Massachusetts, are changing color about three days later than they used to. However, other scientists disagree with the global warming theory. Susan Rose said the leaves in her part of Colorado are changing “right on schedule.” But the leaves in other parts of that state are running a little late. “The lateness in the mountains may have something to do with the really warm late summer and early fall,” she said. “But I’m afraid that’s just a guess.”
小題1:According to Susan Rose, _____.
A．the fall colors are always in leaves
B．leaves make chlorophyll all the seasons
C．leaves’ changing color have nothing to with the weather
D．leaves begin changing color because they start making chlorophyll
小題2:The underlined word “shrinks” in Paragraph 2 could best be replaced by _____.
A．reducesB．increasesC．lastsD．a(chǎn)ppears
小題3:Scientists guess leaves change color later than usual probably as a result of _____.
A．genetic background B．dry weather
C．global warmingD．low temperature
小題4:The purpose of the last paragraph is to tell readers _____.
A．why leaves change color at fall
B．leaves change color at different time
C．the effects of the global warming on plants
D．different opinions on the lateness of leaves’ changing color

The fourth round of heavy smog to hit Beijing in four weeks has sent more people to the hospital with respiratory（呼吸的） illnesses and led to calls for laws to control the pollution.
Pan Shiyi, a celebrity real estate developer said he is planning to propose (提案) a Clean Air Act to the local government. As a representative to the Beijing Municipal People's Congress, he started an online survey at 9:20 a.m. Within three hours, more than 25,000 web users, or 99 percent of total respondents（應(yīng)答者）, welcomed his proposal on Sina Weibo, China's Twitter.
They have good reasons to stand alongside Pan. The latest round of haze（霧霾）reduced visibility to under 500 meters in many parts of the city. The smog has also led to a great increase in respiratory illnesses, particularly among children and the elderly. Anxious parents and doctors almost all blame the smoggy air for the illnesses. Though most schoolchildren are home for the winter holidays, the bad air can easily move indoors. Besides, ordinary medical masks fail to provide adequate protection, so some people have turned to gas masks and respirators（呼吸器）.
The causes of the scary smog are rather mysterious, though experts blame excessive emissions and the mountains around Beijing that trap pollution in winter, unless there is adequate wind to clear it away. Some critics have pointed fingers at China’s top two oil firms, China National Petroleum Corp and China Petrochemical Corporation, saying the companies’ outdated production technologies produce large quantities of substandard, high-polluting gas fuel.
Meanwhile, concerned Beijingers have moved their brainstorming sessions to cyberspace. If Pan’s proposal for a Clean Air Act is adopted, netizens say the new law should include items providing for “car-free days” in times of smog, higher standards for vehicle fuel, stricter restrictions on industrial and exhaust gas emissions, and more effective protection for the public.
Beijing is not the only city that has ever lost the blue sky. Five days of thick fog caused thousands of deaths in Britain in December 1952, urging the government to pass the first Clean Air Act in 1956, which introduced smokeless zones and cleaner fuels to reduce pollution. That may provide some experience for Beijing to refer to.
小題1:What can we learn from the passage?
A．People are clear about the causes of the smoggy weather.
B．Children staying indoors will not get respiratory illnesses.
C．Smog is worse for people with lower resistance to diseases.
D．Masks can give people protection against the smoggy weather.
小題2:Britain is mentioned in the last paragraph to ______.
A．suggest Beijing should learn from other countries
B．let people know many places have this problem
C．tell people the situation in Britain is worse
D．call on the government to pass Britain’s Clean Air Act
小題3:What’s the best title for this passage？
A．The Use of Gas masks and Respirators
B．Beijingers Call for Clean Air Act
C．Effective Protection for Blue Sky
D．The Mysterious Causes of the Scary Smog

Elaine Yu Yee-nee, 15, Creative Secondary School
Lockers are designed in a way to hide their contents for a reason. Otherwise, they’d have open fronts like cupboards. Searching students’ lockers would be total invasion(侵犯) of privacy. Having a locker is more than having a place to store your stuff. A locker also gives you the freedom to keep certain things hidden. These can include harmless personal items like diaries, letters and photos. Searching lockers could discomfit students and others might make fun of them.
Yes, lockers are school property(財(cái)產(chǎn)). But that doesn’t give schools the right to inspect lockers as they please. While students are using lockers, they have the right to keep their contents private. Teachers could ask for permission to take a look inside a student’s locker and if the student is OK with that, then it would be fine. Searching students’ lockers without their permission would result in the loss of trust.
I doubt that students who have something dangerous to hide, such as weapons or drugs, would put them in their lockers. They would not want to risk being caught so easily.
Giving schools the right to search lockers would not help catch those who commit crimes. But it would certainly create an environment in which students would be embarrassed to have their belongings shown in public for no good reason.
Ronald Ling Pak-ki, 20, University of Hong Kong
Many students see their lockers as personal property. They would never agree that schools should have the right to inspect their lockers. But I think schools have an absolute right to do so.
It is the schools that actually own the lockers. Students just use them to store some of their things safely and conveniently. There are clear rules on what items students can and cannot keep in their lockers. Schools have both the duty and the right to check if students are following the rules.
I don’t think school authorities would decide to search a student’s locker unless they felt the need to do so. They might, for instance, suspect students of hiding drugs. To make sure that the process remains open and fair, only authorized teachers should have the right to search lockers. The search should be carried out in such a way as not to embarrass students in front of others.
小題1:What are .the two students talking about?
A．How to make sure schools are safe.
B．Whether there are crimes in schools.
C．Whether schools can search students’ lockers.
D．How to establish trust between teachers and students.
小題2:The underlined word could be replaced by ___.
A．embarrassB．frightenC．worryD．challenge
小題3:According to Elaine, school lockers ____.
A．a(chǎn)re students’ personal property
B．should be changed into cupboards
C．a(chǎn)re likely to hold some dangerous things
D．can be searched with students’ permission
小題4:Which of the following would Ronald agree with?
A．Students won’t hide drugs in lockers.
B．Students use lockers but don’t own them.
C．Students should not put personal things in lockers.
D．Students may forbid teachers to inspect their lockers.

Scientists in Colombia have trained a team of rats to help remove land mines from the countryside. Land mines are small bombs hidden in the ground and designed to explode(爆炸) when someone steps on them.
When trained, the rats can smell special metals in the mines and then signal(發(fā)信號(hào)) to their human team. Then why use rats for such an important job?
In the past, dogs have been used to find bombs. Rats have a good sense of smell and can respond to orders, just like dogs do. But rats are much lighter than dogs. They stand less of a chance of setting off the mines, which explode under a certain amount of weight. What’s more, the best rats are cheaper to keep than dogs. It costs about the same amount of money to take care of one dog as it does 70 rats.
The rats have already been used in Tanzania, an African country with many land mines. Luisa Fernanda Méndez and her team in Colombia are training the even lighter Wistar rats. These are the white rats with red eyes that scientists often use in laboratory experiments. “They even train their babies to perform their jobs, which saves us a lot of time, ” Méndez said.
Colombia has the second-highest rate(比率) of deaths from land mine accidents in the world. Last year, land mines killed 695 people — 56 of whom were children. A criminal group called the Revolutionary Armed Forces of Colombia, or FARC, as well as other organizations, have placed the mines. FARC are strongly against Colombia’s government. The group has placed mines all around its own bases and in many places in the countryside.
In the past, the Colombian government hired peasants and poor farmers to find mines. Many of them died trying to find the well-hidden bombs.
Colombian police official Erick Guzmán hopes the team of rats can come to the rescue(援救). “These rats will be a great help,” he said.
小題1:How do rats help to find land mines?
A．By their special sight. B．By their light weight.
C．By their sense of smell.D．By their excellent hearing.
小題2:The advantage of rats over dogs in finding bombs is that _____.
A．they are cleverer.
B．they run faster
C．they have a better sense of smell
D．they don’t make mines explode as easily
小題3:The underlined word “They” may refer to ______.
A．scientistsB．Wistar rats
C．dogsD．Méndez and her team
小題4: What is the passage mainly about?
A．Specially-trained rats help clear land mines.
B．People in Tanzania are suffering from land mines.
C．Dogs are no longer used to find land mines.
D．Land mines have become a great danger to Colombians.
