Michael Fish may soon be replaced as a weather forecaster by something truly fishier---the shark(鯊魚).
Research by a British biology student suggests that sharks could be used to predict storms.
Lauren Smith, 24, is close to completing her study on shark’s ability to sense pressure.
If her studies prove the theory, scientists may be able to monitor the behaviour of sharks to predict bad weather.
Miss Smith had previously studied the behaviour of lemon sharks in the Bahamas.
She then used their close relatives, lesser spotted dogfish, for further research at Aberdeen University.
Her work---thought to be the first of its kind to test the pressure theory ---- resulted from the observation that juvenile blacktip sharks off Florida moved into deeper water ahead of a violent storm in 2001.
Miss Smith said: “I’ve always been crazy about traveling and diving and this led me to an interest in sharks.”
“I was delighted to have been able to research in the area for my degree. I know there’s so much more we need to understand ---- but it certainly opens the way to more research.”
It has been discovered that a shark senses pressure using hair cells in its balance system.
At the Bimini Shark Lab in the Bahamas, Miss Smith fixed hi-tech sensors to sharks to record pressure and temperature, while also tracking them using GPS (Global Positioning System) technology.
In Aberdeen, she was able to study the effects of tidal(潮汐的) and temperature changes on dogfish----none of which were harmed. She also used a special lab which can mimic(模擬) oceanic pressure changes caused by weather fronts.
She is due to complete her study and graduate later this year. She says she will be looking for a job which will give her the chance to enrich her experience of shark research.

One day when I was driving on the freeway, I noticed all the way there were large dividing walls, which had been built between it and the road running parallel to it, for noise reduction (減少) and a sense of separation. The purpose was to create a sense of privacy (隱私) for people on the other side.
This got me thinking: How often do we put up mental barriers that keep us distant from others? Lifting the artificial barriers that keep us apart can offer opportunities to express our goodwill and create better relationships. If we can do like this, maybe our life will be a little different.
There is a little post office in a nearby town, and since it is closer to me than the post office in my own town, I go there. One day, with many people jammed into the little building, a man came hurrying in to mail a letter, and the girl at the counter saw he had too little postage on it. She told him he needed 2 more cents. Obviously he was a little at a loss. He had hurried over from his office, and didn’t have any money on him or time to stand in line. He was going to run back to get the needed money and wait in line again, but he hurried to get the letter mailed in the first place.
As we were watching him, one woman volunteered a two-cent stamp, and the whole line became very quiet. It was a beautiful moment. The man hesitated for a little while and asked her if she was sure, and she assured him she was fine with giving him the stamp. He offered to go back to his office to get the two cents, and she told him not to bother.
It was a small thing, but it meant something to both of the people involved, and to the rest of us. We aren’t a yard that needs defining or a freeway that needs barriers. We are human beings who can contribute to each other’s wellbeing by taking time to pay attention and interact. After all, we are all parts of a whole living in society.
【小題1】The purpose of the first paragraph is to __________.
| A．summarize the main idea |
| B．give detailed information |
| C．tell readers the author’s opinion |
| D．introduce the topic |
| A．The man went back to his office immediately. |
| B．The man turned to a lady for help. |
| C．A woman offered a stamp to the man. |
| D．The man waited in line patiently. |
| A．She pays too much attention to privacy. |
| B．She believes people should participate in the world around them. |
| C．She confuses real barriers with false ones. |
| D．She insists all small things always have the greatest meaning. |
| A．Artificial Barriers | B．Unnecessary Separation |
| C．An Unforgettable Experience | D．The Kindness of People |

John, a famous musician, took his priceless antique violin and played it in the crowded subway station. The music from the violin was delicately streaming throughout the whole station. However, during the one-hour play, only six or seven people were truly appreciating the charming music. A three-year-old kid was so fascinated by the music that he forgot everything around. John only got 52 dollars for his work that day.
However, in normal days, when John is about to hold a concert, one ticket can be sold at more than 100 dollars and it is extremely hard to buy a ticket even at such a high price. Therefore, later, many passers-by in the station that day felt deeply regretful for not recognizing the famous musician and missing such a valuable but cheap music feast.
I have a very busy friend who had totally changed after knowing that his wife came down with incurable illness. He cooked by himself for the family and took a walk with his wife every day. Nonetheless, his wife still did not manage to conquer the illness and passed away after three months. After that, he often sighed miserably that due to his past busy life, he had missed a lot of beautiful time with his wife. But now, it is impossible to make up for it.
It is no use crying over spilt milk. We have missed a lot of precious things in our life without knowing to cherish them.
Actually, I also missed something precious before. The reason why we would have missed those precious things is less than simple: we had thought that we could still own them tomorrow.
Nevertheless, tomorrow is actually by no means reliable. There was a famous Buddhist monk saying that in many people’s lives, they have only done two things: waiting and regretting. The result is that they were always too late to cherish what they had before they lost it. We would often claim to do something when we grow up, or when we have money or when we become old, etc. However, when we reach the condition we have expected, we could no longer realize our wish, because we have lost it by then.
【小題1】The reason why people often regret may be that _______.
| A．they are too busy to notice the beautiful things |
| B．they are too careless to cherish precious things |
| C．they are lazy to observe the surroundings |
| D．they think that it’s none of their business |
| A．a(chǎn)ctions speak louder than words |
| B．a(chǎn) bad beginning makes a bad ending |
| C．the lost will never come back |
| D．each day brings its own bread |
| A．By listing data. | B．By comparing the details . |
| C．By explaining the procedures . | D．By taking examples. |
| A．Many people will not cherish what they have until they lost them. |
| B．Many people cannot do well until they get older. |
| C．Many people know what they are doing. |
| D．Many people regret for what they don’t possess. |

Bad behavior is something that most people don’t want to tolerate. However, we have had to tolerate it more and more with each passing year. There seems to be no concern for other people’s feelings; nor do we seem to care about other people’s property. We live in an age where saying what is on our minds has priority over any harm that it might do.
There are ways to deal with bad behavior in modern times, though. Too many of us let bad behavior go because we don’t want to rock the boat. This is the time that you should rock the boat and rock it hard. Let people know that you expect it to change. That is the key to dealing with bad behavior. If it continues, take the proper action for the situation you are in. If you have developed the habit of bad behavior, take a hard look at it and then change it. You can’t expect others to behave well if you aren’t willing to look at your own bad behavior and change it.
If you don’t have control over anything in a situation, just walk away from it and move on to something that you do have control over. You needn’t feel ashamed of that. Besides, you must stand firm in what you believe. You can’t control what other people do, but you can control what you do about it. You can’t go wrong if you stand firm in what you believe. Understanding your responsibility is also important. Don’t try to take on the responsibility for other people’s behavior. Take care of what you have to and do it in the way you know it should be done. The rest will take care of itself.
Bad behavior is on the rise with more and more people behaving badly without having to pay any consequences. Worry about how you behave rather than how others behave. Pretty soon, it just may catch on.
【小題1】It can be inferred from Paragraph 1 that _____________.
| A．bad behavior is common today |
| B．bad behavior is sure to hurt people deeply |
| C．people behave badly because of carelessness |
| D．people are more understanding than before |
| A．fight it bravely whenever it happens |
| B．ignore it if it is beyond your control |
| C．let it go to avoid trouble |
| D．make people feel ashamed of their bad behavior |
| A．Because bad behavior is often ignored. |
| B．Because people are often influenced by others. |
| C．Because people aren’t punished for their bad behavior. |
| D．Because people haven’t realized its consequences. |

Parents feel that it is difficult to live with teenagers. Then again, teenagers have feelings about their parents, saying that it is not easy living with them. According to a recent research, the most common between parents and teenagers is that regarding untidiness and daily routine tasks. On the one hand, parents go mad over rooms, clothes thrown on the floor and their children’s refusal to help with the . On the other hand, teenagers lose their patience continually when parents blame them for the towel in the bathroom, not cleaning up their room or refusing to do the shopping at the supermarket.
The research, conducted by St. George University, shows that different parents have different to these problems. However, some approaches are more than others. For example, those parents who yell at their children for their untidiness, but clean the room for them, have fewer chances of changing their children’s . On the contrary, those who let teenagers experience the of their actions can do better. For example, when teenagers who don’t help their parents with the shopping don’t find their favorite drink in the refrigerator, they are forced to their actions.
Psychologists say that is the most important thing in parent-child relationships. Parents should to their children but at the same time they should lend an ear to what they have to say. Parents may their children when they are untidy but they should also understand that their room is their own private space. Communication is a two-way process. It is only by listening to and each other that problems between parents and children can be settled.

While Jennifer was at home taking an online exam for her business law class, a monitor（監(jiān)控器）a few hundred miles away was watching her every move.
Using a web camera equipped in Jennifer’s Los Angeles apartment, the monitor in Phoenix tracked how frequently her eyes moved from the computer screen and listened for the secret sounds of a possible helper in the room. Her Internet access was locked - remotely - to prevent Internet searches , and her typing style was analyzed to make sure she was who she said she was: Did she enter her student number at the same speed as she had in the past? Or was she slowing down?
In the battle against cheating, this is the cutting edge and a key to encourage honesty in the booming field of online education. The technology gives trust to the entire system, to the institution and to online education in general. Only with solid measures against cheating, experts say, can Internet universities show that their exams and diplomas are valid - that students haven’t just searched the Internet to get the right answers.
Although online classes have existed for more than a decade, the concern over cheating has become sharper in the last year with the growth of "open online courses." Private colleges, public universities and corporations are jumping into the online education field, spending millions of dollars to attract potential students, while also taking steps to help guarantee honesty at a distance.
Aside from the web cameras, a number of other high-tech methods are becoming increasingly popular. Among them are programs that check students’ identities using personal information, such as the telephone number they once used.
Other programs can produce unique exam by drawing on a large list of questions and can recognize possible cheaters by analyzing whether difficult test question are answered at the same speed as easy ones. As in many university classes, term papers are scanned against some large Internet data banks for cheating.
【小題1】Why was Jennifer watched in an online exam?
| A．To correct her typing mistakes. |
| B．To find her secrets in the room. |
| C．To prevent her from slowing down. |
| D．To keep her from dishonest behaviors. |
| A．a(chǎn)dvanced technique | B．sharpening tool |
| C．effective rule | D．dividing line |
| A．they can attract potential students |
| B．they can defeat academic cheating |
| C．they offer students online help |
| D．they offer many online courses |

Far from the land of Antarctica, a huge shelf of ice meets the ocean. At the underside of the shelf there lives a small fish, the Antarctic cod.
For forty years scientists have been curious about that fish. How does it live where most fish would freeze to death? It must have some secret. The Antarctic is not a comfortable place to work and research has been slow. Now it seems we have an answer.
Research was begun by cutting holes in the ice and catching the fish. Scientists studied the fish’s blood and measured its freezing point.
The fish were taken from seawater that had a temperature of -1.88℃ and many tiny pieces of ice floating in it. The blood of the fish did not begin to freeze until its temperature was lowered to -2.05℃. That small difference is enough for the fish to live at the freezing temperature of the ice-salt mixture.
The scientists’ next research job was clear: Find out what in the fish’s blood kept it from freezing. Their search led to some really strange thing made up of a protein never before seen in the blood of a fish. When it was removed, the blood froze at seawater temperature. When it was put back, the blood again had its antifreeze quality and a lowered freezing point.
Study showed that it is an unusual kind of protein. It has many small sugar molecules held in special positions within each big protein molecule. Because of its sugar content, it is called a glycoprotein. So it has come to be called the antifreeze fish glycoprotein. Or AFGP.
【小題1】What is the text mainly about?
| A．The terrible conditions in the Antarctic. |
| B．A special fish living in freezing waters. |
| C．The ice shelf around Antarctica. |
| D．Protection of the Antarctic cod. |
| A．The seawater has a temperature of -1.88℃. |
| B．It loves to live in the ice-salt mixture. |
| C．A special protein keeps it from freezing. |
| D．Its blood has a temperature lower than -2.05℃. |
| A．A type of ice-salt mixture. | B．A newly found protein. |
| C．Fish blood. | D．Sugar molecule. |
| A．sugar | B．ice |
| C．blood | D．molecule |

February has long been a month of romance. With the sweet smell of roses in the air, romantic films hit cinemas and love stories fill newspapers and magazines.
On the 14th day, it is a custom for a boy to take his girlfriend out to dinner, buy her flowers and chocolates, write poems, sing to her or even spell out her name with rose petals! This is what you see on Valentine’s Day, a day named after Valentine who was a priest in the third century Rome. When the emperor (皇帝) decided that single men could become better soldiers than those with wives, he didn’t allow marriage.
But Valentine continued to perform marriage ceremonies for young lovers in secret. When his actions were discovered, the emperor sentenced him to death. While in prison, it is said that Valentine fell in love with the daughter of his prison guard. Before his death, he wrote her a letter, which he signed “From your Valentine”, an expression that is still in use today. Valentine died for what he believed in and so he was made a Saint (圣徒), as well as becoming one of history’s most romantic characters.
Nowadays, Valentine’s Day is also popular among Chinese young people. Some students are planning to make Valentine’s cards for parents, teachers and friends. Others want to hold parties at which they will exchange small gifts and eat heart-shaped cakes. The idea is to have fun and encourage people to share in the spirit of St. Valentine.
【小題1】Why did the emperor in Rome not allow marriage in his country?
| A．Because there were few women in his country at that time. |
| B．Because he thought men without wives could be better soldiers. |

It's common for parents to feel emotional when the moment comes for their child to leave home and go to university. Even parents who don't speak about the event are likely to feel a sense of sadness because it’s the end of an era where you and your family were at the centre of your child's world. As a parent you’ll probably continue to support your child in different ways, but the main job of raising your child is over. It's a huge change for everyone involved.
There are a few things that you can do to make the transition easier. Plan carefully for your child's departure and think about how you can help. Many parents take their child to university for the first time. If you decide to do that, be ready to feel a real wrench when the time comes to say goodbye. Your child will probably be as nervous as you are about the moment when you finally say goodbye – but that might not show!
Be positive and cheerful about the choice your child has made to continue studying, and plan to leave once you've unpacked the car and looked around your child's new living accommodations. If you can, save your tears for the car – you'll make things easier on your child and yourself.
The more you've invested in being a parent, the more you'll feel a sense of loss, so the sadness you feel now is a sign that you've been a good mom or dad. Remind yourself that parenting is all about raising an independent and confident child who functions well without you. If your child quickly settles and starts enjoying himself, you should congratulate yourself.
It's also only fair to allow yourself some time to grieve(悲痛). Don't expect to pick yourself up and move on straight away. But you may decide to find a hobby or sport to fill your extra time. Perhaps you've always wanted to learn a new language, go to yoga classes or take up swimming. You may decide to spend more time with family and close friends, who are likely to be feeling the absence of your child as well.
Agree on the best approach to staying in touch before your child leaves, and stick to your agreement. Try not to panic if your child doesn't respond immediately – remember, they're starting a new and busy life.
【小題1】Why do parents feel sad when their child leaves home for college?
| A．Because the absence of their child makes them feel lonely. |
| B．Because their children will start a new life in college. |
| C．Because it means the end of love between parents and their child. |
| D．Because they are no longer the main focus of their children’s life. |
| A．sorrow | B．regret | C．a(chǎn)nger | D．love |
| A．Supporting your child in different ways all the time. |
| B．Congratulating yourself when your child goes to college. |
| C．Preparing your child to stand on their own feet in the future. |
| D．Investing as much as possible in the growth of your child. |
| A．Developing a new hobby or sport |
| B．Learning a new language. |
| C．Spending more time with close friends |
| D．Staying in touch with your child. |
| A．Staying in Touch with Your Child |
| B．Preparing to Say Goodbye to Your Child |
| C．Dealing with Your Child Leaving Home for University |
| D．Life after Your Child Has Left Home for University |
