Honey from the African forest is not only a kind of natural sugar, it is also delicious.
Most people, and many animals, like eating it. However, the only way for them to get that honey is to find a wild bees' nest and take the honey from it. Often, these nests are high up in trees, and it is difficult to find them. In parts of Africa, though, people and animals looking for honey have a strange and unexpected helper - a little bird called a honey guide.
The honey guide does not actually like honey, but it does like the wax in the beehives (蜂房). The little bird cannot reach this wax, which is deep inside the bees' nest. So, when it finds a suitable nest, it looks for someone to help it. The honey guide gives a loud cry that attracts the attention of both passing animals and people. Once it has their attention, it flies through the forest, waiting from time to time for the curious animal or person as it leads them to the nest. When they finally arrive at the nest, the follower reaches in to get at the delicious honey as the bird patiently waits and watches. Some of the honey, and the wax, always fall to the ground, and this is when the honey guide takes its share.
Scientists do not know why the honey guide likes eating the wax, but it is very determined in its efforts to get it. The birds seem to be able to smell wax from a long distance away. They will quickly arrive whenever a beekeeper is taking honey from his beehives, and will even enter churches when beeswax candles are being lit.
小題1:Why is it difficult to find a wild bees' nest?
A.It's small in size.B.It's hard to recognize.
C.It's covered with wax.D.It's hidden in trees.
小題2:What do the words "the follower" in Paragraph 2 refer to?

小題3:The honey guide is special in the way ________.
A.it goes to churchB.it gets its food
C.it sings in the forestD.it reaches into bees' nests
小題4:What can be the best title for the text?
A.Wild BeesB.Wax and Honey

The argument over a Philadelphia school district accused of secretly spying on pupils through laptop cameras became fiercer today after it acknowledged obtaining more than 56,000 images of its students, many of them in their homes.
When the scandal (丑聞) first broke, it was believed that only a few pictures had been taken of one pupil, Blake Robbins. But court papers released this week showed that thousands of images were taken of Robbins and other students.
Robbins and his parents have filed an action against the school district. Court papers from the Robbins’s lawyers said that at first it was thought that the laptops’ technology had produced a few images but they found more than 400 of Robbins, including images “showing him partially undressed and sleeping”.
Robbins said he did not know why the spying device was activated (激活) as his laptop had not been reported stolen or missing. Other students whose pictures were taken said their laptops had not been reported stolen or missing either.
An administrator at the school, one of the few with authority to track the laptops, remained silent, refusing to answer questions.
The Philadelphia Inquirer reported that 38,500 of the images came from six laptops that had been reported missing from the Harriton gym in September 2008. These apparently helped the police catch a suspect. Another set of images were from cameras in laptops which employees responsible for tracking failed or forgot to turn off.
The court papers, filed by Robbins’ lawyers, said that the technology was activated between 20 October and 4 November last year, with most of the 400 shots of him while he was in his home, and included his family. “There were additional webcam pictures and screen shots taken of Blake Robbins which, up to now, have not been recovered because the evidence was deleted by the IT department,” the court papers say.
One of Robbins’ lawyers is trying to obtain access to the administrator’s home computer to confirm whether she downloaded any of the pictures. The court papers indicate she may be a voyeur (窺隱私者) though it has not been proved.
小題1:We can learn from the passage that _________.
A.Robbins’ parents remained calm over the scandal
B.Robbins had his laptop stolen before the scandal
C.the laptops’ technology produced some images
D.the private rights of the students were offended
小題2:What did The Philadelphia Inquirer say about the case?
A.The police had found some evidence.
B.Most of the laptops in Harriton gym were missing.
C.Employees in charge of tracking deliberately left the laptops on.
D.There was obviously more than one suspect related to the case.
小題3:According to the court papers, the administrator _________.
A.may have spied her students on purpose
B.may have broken into Robbin’s house
C.has downloaded many students’ pictures
D.has removed evidence from computers
小題4: What does the passage mainly talk about?
A.Modern technology has negative effects on our lives.
B.Students in Philadelphia are accustomed to being spied on secretly.
C.A Philadelphia school is charged with spying students through laptop cameras.
D.The American government should take measures to improve teachers’ qualities.

Since the beginning of history, man has been attracted by the idea of living forever, of winning the fight against death and disease. So far, this has only remained a dream. Many people have wondered whether it would be possible to find a way to preserve human bodies, and what would be the best way.
It has long been known that meat of fruit can be kept fresh for long periods by freezing; in ancient China, for example, food was stored with ice to keep it fresh. This method could also be useful for preserving humans.
However, most living beings that exist under warm conditions die when frozen. This is because of the harmful effects of freezing ice crystals(晶體), which not only are larger than the volume(體積) of the water originally in the cells, but also form sharp cutting shapes that harm the cells.
In the 1940s Dr B.J. Luyet and a group of scientists in England were working on the problem of freezing cells without damaging them. Since the harm caused by ice crystals was the main cause of damage, Luyet suggested removing some or all of the water from the cells before freezing them.
Using living cells form chicken, Luyet and his assistants discovered that they could partly dry the chicken cells, using a mixture of the white part of an egg and glycerin (丙三醇). Some success was obtained. The chicken cells were dried, frozen for a period of time, and then carefully unfrozen. Almost all the cells recovered when they reached normal temperatures.
Since then, the cooling of whole animals to a temperature far below freezing point for later unfreezing has become more of a possibility, and the glycerin method would probably be used to accomplish this. When this can be done completely and successfully, science will have moved much closer to its aim of freezing and storing incurable patients until the day they can be cured.
小題1:What does the passage mainly talk about?
A.Easy but practical ways to remove water from living cells.
B.The possibility of preserving human bodies by freezing.
C.The practice of preserving food by freezing.
D.The harmful effects of freezing.
小題2:The idea of freezing human bodies to preserve them ______________.
A.has already been realized
B.was invented in ancient China
C.has its roots in the way of storing food
D.is widely accepted by the scientific world
小題3:According to the text, freezing _________________.
A.is harmful to living cells
B.is the best way of preserving food
C.reduces the volume of water in living cells
D.is a way of removing water from living cells
小題4:What can be inferred from the last paragraph?
A.It is impossible to have whole animals frozen.
B.It remains unknown how to unfreeze frozen animals.
C.Freezing incurable patients for later treatment is still an idea.
D.The glycerin method has already been adopted to treat patients.

Air is an odorless (無氣味的), invisible (看不見的) gas that surrounds the earth. It is everywhere on the planet. An “empty” drinking glass and an “empty” room, to give two examples, are not really empty. Each is filled with air. When the glass is filled with water, the water pushes the air out of the glass.
Air, as a gas, has no definite (明確的) shape, but, because it is matter, it takes up space. It is easy to prove that air is something that takes up space. Stuff a dry handkerchief into the bottom(底部) of a glass so that it will not fall out when the glass is turned upside-down. Push the upside-down glass; hold it straight into a jar of water till the glass is completely covered. When the glass is taken out of water, the handkerchief will be dry. The air inside the glass takes up space and keeps the water from coming in.
小題1:What does the underlined word “Stuff” (in Paragraph 2) mean?
A.Press tightly. B.Take out.
C.Put down.D.Turn fully.
小題2:The writer tells us that _______.
A.the experiment is done in the laboratory
B.the experiment is done outside the room
C.the experiment is easily done
D.the experiment is carried out indoors
小題3:Which of the following pictures gives us the correct result?
( W—water;  A—air;  H—handkerchief )

Trying to make a big decision while you’re also preparing for a scary presentation? You might want to hold off on that. Feeling stressed changes how people weigh risk and reward. However, an article published in Current Directions in Psychological Science, a journal of the Association for Psychological Science, suggests stressed people pay more attention to the positive sides of a possible outcome.
It’s a bit surprising that stress makes people focus on the way things could go right, says Mara Mather of the University of Southern California. She co-wrote the review paper with Nichole R.Lighthall. “This is sort of not what people would think, ” Mather says. “Stress is usually associated with negative experiences, so you’d think, maybe I’m going to be more focused on the negative outcomes.”
But researchers have found that when people are under stress, they start paying more attention to positive information and discounting negative information. “Stress seems to help people learn from positive feedback and impairs(削弱)their learning from negative feedback, ” Mather says.
When people under stress are making a difficult decision, they may pay more attention to the good sides of the alternatives they’re considering and less to the problems. So someone who’s deciding whether to take a new job and is feeling stressed by the decision might focus on the increase in salary more than the longer commute(上下班往返).
The increased focus on the positives also helps explain why stress plays a role in addictions. People under stress have a harder time controlling their urges. “The compulsion to get that reward comes stronger and they’re less able to resist it,” Mather says. A person who’s under stress might think only about the good feelings they’ll get from a drug, while the downsides shrink into the distance.
Stress also increases the differences in how men and women think about risk. When men are under stress, they become even more willing to take risks; when women are stressed, they get more conservative(保守的). Previous research backs this up — men usually react to difficulties while trying to fight them or escape them; women try to find friends and improve their relationships.
小題1:By saying “You might want to hold off on that” in the first paragraph, the writer suggests that      .
A.you might want to delay making your big decision
B.you should save the presentation for later
C.you should avoid taking risks
D.you might benefit from the stress
小題2:From the article, we can conclude that stress       .
A.often leads people to take more risks
B.often leads people to make balanced decisions
C.makes people think more of negative results
D.makes people ignore the negative side of problems
小題3:Which of the following is TRUE according to the article?
A.Stress is helpful in getting rid of addictions.
B.People who are addicted to drugs are easily stressed.
C.When women are stressed, they do not tend to take risks.
D.When men are stressed, they are more likely to develop an addiction.
小題4:What is the central theme of the article?
A.Stress can affect decision-making.
B.Stress increases our desire to get rewards.
C.We should think more about the upside of problems.
D.There is a link between stress and negative experiences.

Certain animals know without analysis the difference between a number of objects and a smaller number. In his book The Natural History of Selbourne (1786), the naturalist Gilbert White tells how he surreptitiously removed one egg a day from a kind of bird Plover’s nest, and how the mother laid another egg each day to make up for the missing one. He notes that other kinds of birds ignore the loss of a single egg, but if more than one egg has been removed, they will give up their nests. It has also been noted that a certain type of bees always provides five—never four, never six—caterpillars (毛蟲) for each of their eggs so that their young have something to eat when the eggs have hatched out. Research has also shown that both mice and pigeons can be taught to distinguish between odd (奇數(shù)) and even (偶數(shù)) numbers of food pieces.
These have led some people to think that creatures can actually count. They also point to dogs that have been taught to respond to questions about numbers with the correct number of barks.
Animals respond to quantities only when they are connected to survive as in the case of the eggs, or survive as in the case of food. They can “count” only when the objects are present and only when the numbers involved are small—no more than seven or eight. In lab experiments, animals which are trained to count one kind of objects were unable to count any other type. What interests them are the objects, not the numbers. Animals’ achievements simply are not equal to evidence of counting. They only show the results of clever, careful training.
小題1:The author refers to Gilbert’s book in paragraph 1 in order to_______.
A.support the idea that animals can count
B.show attitudes have changed since 1786
C.prove that some animals are aware of quantities
D.indicate that more research is needed in this field
小題2:The author mentions all of the following are aware of quantities in some way EXCEPT _______.
A.caterpillarsB.bees
C.miceD.plovers
小題3:The underlined word “surreptitiously” probably means _______.
A.quicklyB.carefully
C.occasionallyD.secretly
小題4:Where does this text probably come from?
A.A news report.B.A science fiction.
C.A park guide.D.A biology magazine.

Few of us act alone in the real world. Most things are done with the help or ideas of other people. Group projects are great practice for high school, college, and real life, when you will probably have a job that requires working with others. Right now, group projects can be fun and they often allow you to do a bigger, more interesting project than you could alone. With group work, you can actually learn more in less time.
Group projects also give you a chance to get to know kids you might not otherwise know or talk with. Group projects are also a great way to practice skills you’re not so sure of. For example: working on a deadline, staying organized, or being patient. And if you’re a little nervous talking in front of a group, a joint project can help you become more comfortable with it. Maybe your group will pick you to tell the whole class about your project. If so, you’ll know your whole group is rooting for you!
One of the most important things about group work is talking and meeting together. It’s a good idea to continually check with everybody on their progress to see if anyone needs help. You might think the first step is to figure out who will do what, but actually it’s getting to know another a little. Take a few minutes to chat. Even if you know each other well, it can help to take a minute to think about your skills and share your strengths and weaknesses. The second step is to go over ground rules from your teacher and any that you want to create together as a group.
小題1:Group projects can give you a chance to do the following EXCEPT ________.
A.get to know more friendsB.learn more than you do alone
C.work in an organized wayD.get rid of shyness forever
小題2:The underlined phrase “root for” in the second paragraph means _______.
A.likeB.supportC.offerD.prevent
小題3:What’s the purpose in checking others’ progress?
A.To learn what they will do next.
B.To find good topics to talk with them about.
C.To help them when they need help.
D.To make sure that their work is finished on time.
小題4: According to the passage, we can infer that _______.
A.group members should be your close friends
B.talking with group members should be the first step of group work
C.knowing persons is more important than your projects
D.rules from teachers are more important than working among group members

Still waiting for little green men to make contact? Don't hold your breath.
A leading astronomer has concluded there probably aren't any aliens out there – meaning we are absolutely alone in the universe.
Even though there may be tens of thousands of other distant planets similar in size to Earth, the conditions on them are likely to be too hard to support life-forms such as ET.
Dr Howard Smith, a senior astrophysicist at Harvard University, believes there is very little hope of discovering aliens and, even if we did, it would be almost impossible to make contact.
So far astronomers have discovered a total of 500 planets in distant solar systems – known as extrasolar systems – although they believe billions of others exist.
But Dr Smith points out that many of these planets are either too close to the sun or too far away, meaning their surface temperatures are so bad that they could not support life. Others have unusual orbits which cause vast temperature variations, making it impossible for water to exist – the most important thing for life.
Dr Smith said, "We have found that most other planets and solar systems are wildly different from our own. It means it is highly unlikely there are any planets with intelligent life close enough for us to make contact." But his suggestions contradict other leading scientists who have claimed aliens almost certainly exist.
Only last month Professor Stephen Hawking said the fact that there are billions of galaxies out there made it reasonable to think there were other life-forms in the universe.
Researchers from the University of London have recently suggested that aliens could be living on as many as 40,000 other planets. But Dr Smith said: "Any hope of contact has to be limited to a relatively tiny space around the Earth, reaching maybe 1,250 light years out from our planet, where aliens might be able to pick up our signals or send us their own. But communicating would still take decades or centuries."
小題1:By saying "don’t hold your breath", the author advised the reader not to _____.
A.keep silentB.give upC.expect soD.be afraid
小題2:Dr Smith concludes there probably aren’t any aliens because other planets _____.
A.a(chǎn)re too far away from the earth
B.a(chǎn)re different from the Earth in size
C.don’t have rich natural resources
D.don’t have a suitable living environment
小題3:Researchers from the University of London are mentioned to show that ______.
A.they have better explanations about aliens
B.a(chǎn)liens certainly exist on many planets
C.they disagree with Dr Smith’s suggestion
D.a(chǎn)liens can pick up signals from the earth
小題4:What’s the main idea of the text?
A.There must be other life forms in the universe.
B.We can communicate with aliens in decades.
C.The chances of finding aliens are slight.
D.Many other planets are quite different from the Earth.
