The summer beach season is prime time for shark attacks. It seems like sharks are attacking all the time .But that is something of an illusion. The number of attacks is very small.
How does a shark hunt? Muscles and fins (鳍)give the shark its speed and maneuverability(灵活)in the water. A shark’s front fins act like the wings of a plane and let it “fly” through the water. The tail acts like a high-power propeller(推进器).
But the big thing that gives the shark its edge in the ocean is its sensory package. The package includes the shark’ eyes ,ears ,skin, nose and mouth, as well as electric sensing.
A shark' nose is probably its most important sense. If you were to put a single drop of blood in a swimming pool ,a great white shark could smell that. And they can tell the direction that the smell is coming from.
Sharks handle their electric sensing using cell located in the head .Whenever something moves using its muscles , a shark can detect the electrical impulses（脉冲）flowing to those muscles. A shark can electrically “see” anything that has muscles even if it is hiding or the water is not clear.
Sharks even have vibration sensors in their skin. Even something moves near the shark ,tubes pick up the pressure changes and hairs inside the tubes send signals to the brain . This extra sense allows a shark to turn quickly and attack again.
When you put all these different senses together ,it makes the shark a nearly ideal hunter. A shark can detect prey from miles away and then use eyes ,electrosensing and movement sensing to home in .
Strangely, sharks do not seem to use these senses to home in on people. The very low number of sharks tells us that sharks do not hunt people on a regular basis. On the other hand , people love to hunt sharks. Millions of sharks die every year. Without protection ,extinction is a definite possibility.From the text ,we can know that____________________.

His first successful fight was for the equal rights of black people in South Africa. Then, as the first black president, he fought to unite the country and organize the government. Now Nelson Mandela has set his sights on a new enemy, AIDS.
On March 19 the 82-year-old, former president, hosted his second AIDS-awareness concert. He warned that 25 million people in Africa were already infected with the fatal disease.
Mandela was born in a small village in South Africa in 1918. He was adopted by the chief of his tribe and could have been a chief himself and lived a happy country life.
But he refused to be a chief when his people lived under racial discrimination(歧视). He decided to fight for equal rights for all the people in South Africa. Before 1990, under the country’s Racial Segregation Law, colored and white people lived separately. Black people were treated unfairly even when taking a bus. Blacks had to stand at the back of the bus to make room for white people even when there were only a few of them on board.
For his opposition to the system, Mandela was arrested and spent 27 years in prison. He was freed in 1990 and became the president of the country after the first election were held in which everyone could vote.
Mandela was not only a political fighter who attacked with speeches. He was also a trained boxer and fought in the ring when he was young.
“Although I did not enjoy the violence of boxing, I was interested in how one moved one’s body to protect oneself, how one used a strategy both to attack and retreat”, he wrote in his autobiography.
As a skillful fighter, he chose music as his weapon against AIDS. He hopes to win another victory against AIDS.When was Mandela arrested?
| A．In 1963 |
| B．In 1990 |
| C．When he refused to be a chief |
| D．When he became the president |
Nelson Mandela succeeded in doing the following except _______.
| A．winning the equal rights for the black people in South Africa |

| C．organizing a government in South Africa |

If Nelson Mandela hadn’t fought against racial discrimination, he_______.
| A．could have been the president of South Africa |
| B．could still have lived a happy life |
| C．could have been in a difficult situation |
| D．would have been an excellent boxer |
Which of the following statements can best describe the life of Nelson Mandela?

I have been a student at Bentley College in Waltham for some time now, so I have a lot of experience and know how things work at Bentley. As a freshman(新生)at Bentley College you will be living in the Tree Dorms, Slade Hall or Miller Hall. I would highly suggest that you choose to live in the Tree Dorms because this is where most fresh-men are going to be living. There will be a lot of activities going on in the building and you will meet lots of people. Slade Hall is next to the parking lot and not far from the Tree Dorms, so that would be your second choice. As Miller Hall is small and far away, it would be my last choice for freshmen housing. If Bentley offers you the chance to live with second or third year students you’d better refuse their offer and live with freshmen. Living with your classmates will make the transition (过渡) into college life a lot easier.
As a freshman your classes should be easy. After freshman year your classes will become a lot more difficult, so I advise that you get down to business early in the first year. There are two very easy things you can do to increase your knowledge as a freshman. The first is to just go to class and the second is to always do your homework. I also highly advise that you do it on your own and try to stay disciplined. It is too easy to put your homework away and then get really behind and not be able to learn everything before a mid-term or final exam. The author advises freshmen to live in the Tree Dorms because ___________.
| A．it is across the parking lot from Slade Hall |
| B．it is small and quite far away from the playground |
| C．there are many second and third year students there |
| D．there are many freshmen and more activities |
Where is Slade Hall?
| A．Near Miller Hall. | B．Far from Tree Dorms. |
| C．Beside the car park. | D．Near the classrooms. |
According to the author, how can freshmen improve knowledge?
| A．Remember to do homework by discussing it with others. |
| B．Finish homework and go to class every day. |
| C．Try to spend more time in the library. |
| D．Be able to learn something before a mid-term or final exam. |
The author writes the passage to ___________.
| A．tell new students how to get used to college life |
| B．tell new students about their teachers and dormitory |
| C．show the differences between college and high school |
| D．tell readers about some funny things at Bentley College |
Maybelle said she wouldn't be coming with me to the library. I asked why, and she said she could get all the short stories she wanted off the Internet. Saved walking all the way to the library, and putting up with my long chat on the way there, and on the way back. Maybelle is very direct like that, always has been.
"But, Maybelle, we've been walking to the library every Monday for the last fifty years!"
She said," Why don't you get Internet'? We can send each other emails."
So I had to get Internet. I called the local high school. They said they'd send me a good student to tell me all about computers and such.
Evil thing, this Internet. Makes you lose old friends, forces you to learn new complex ideas, even if you're too old. But Maybelle said you have to be modern; otherwise, you're dead.
The kid came the next day. Tall skinny black kid, by the name of Arsenius, said his work would cost more.
I said, "All right. As long as I get Internet."
"You need a computer, then you need to get hooked up," he said.
"Let's buy a computer and get hooked up, then."
"How much you want to spend?"
"Whatever it takes."
"How many rams you want?"
I wasn't going to show him my ignorance, so I said, "Whatever it takes."
"Let's go to the mall. You got a car?"
"In the garage."
When I opened the garage door, he gasped. Daddy's car is still there, a'57 Chevy. I never drive it. Walk everywhere.
I said," Let's walk. It's only a mile or so."
He said," Let's drive, or you will faint on me in this heat."
"Young man, I don't faint, never have. We're walking."
"I get paid by the hour," he said. "Walking will cost you a lot more. Also, you feel like carrying a computer a mile or so?"What kind of person is Maybelle?
| A．She always says what she means in an honest way. |
| B．She no longer likes reading in her old age. |
| C．She doesn't want to be friends with the writer any more. |
| D．She doesn't want to keep up with the time. |
Why does the writer want to have Internet at his place?
| A．Because the writer believes that one is never too old to learn. |
| B．Because the writer thinks that it is better late than never. |
| C．Because of the pressure from people of his age. |
| D．Because of the convenience the Internet will bring. |
Arsenius gives _________ reasons for driving to the mall.
| A．two | B．three | C．four | D．five |

Searching for the truth
Collecting and writing news is like researching in history: the best information comes from those who were there at the time. So if' we want to study the history of China in the sixth century AD, we look at the writings of the people who lived then. They are called the primary sources because they tell us what it was like to live then. People at a much later date who write about the same events are called the secondary sources. For example, when we read the original writings of Jia Sixie on agriculture, we are reading a primary source; when we read about Jia Sixie in our textbook we are reading secondary source because the passage was written about him and his ideas many years after he died.
When we make news, we use primary and secondary sources. We can see this most clearly in TV programmes. As we watch the news on TV, the person presenting the programme in the studio is the secondary source( because he tells us about the news) and the reporter in Iraq or Washington is the primary source (because he is telling us about what is actually happening there). Without these reporters acting as primary sources, you would never find out what really happened in a war, earthquake, sports meeting, concert or festival. These reporters explain what is happening, so we have a clearer idea of what is going on there. They often take photographers with them who act as primary source by giving pictures of events.
In a newspaper, the position is different because these two roles are often combined. This means a reporter who investigates a story may be the same person who writes it. If this happens, the reporter is both the primary and the secondary source. But the photographer who works with him/her is still a primary source.
One of the reasons that it is important to separate primary and secondary sources is that they help us to decide what is a fact and what is an opinion. A fact is something that everybody agrees has happened. An opinion is somebody's idea of what happened. So facts and opinions are often mixed in any report, whether in a newspaper or on TV.
