When was the last time you relied on an old-fashioned map to figure out the route to an unfamiliar place? For many, the GPS has revolutionized navigation, making a paper map almost obsolete? So how has this piece of technology developed over its 26 years of existence? On February 14,1989,the first satellite in the US Global Positioning System was sent into space from Cape Canaveral, beginning the start of one of the wonders of the modern world.
GPS stands for Global Positioning System, which is made of a network of around 30 satellites that move around the earth. The system uses a process called trilateration to find out one’s position. By measuring the time it takes for the signal to reach one satellite, the GPS can determine your distance from the satellite, creating a sphere(范围) of possible locations. Measuring your distance from at least three satellites will narrow your location to the place where the three spheres cross one another, to the accuracy(精确) of about less than 1 meter!
The GPS was first invented during the Cold War by the United States Department of Defense. In 1960, the first system, which was made of just five satellites, was put into place. It was initially created for strictly military(军事的) use; however, in 1983, as a result of faulty navigation technology, a Korean passenger plane mistakenly flew into USSR territory(苏联领土) and was shot down. In order to prevent such bad events, American President Ronald Reagan allowed civilian(民用的) use of the GPS.
Over the next ten years, the system’s accuracy improved as the network was increased to 24 satellites. And during the first Persian Gulf War, the new GPS was finally used by the military. Now scientists use the technology to track animals to better understand their movement and behavior. Parents who may be worried about their children can also use GPS technology to track them.
1.The underlined word “obsolete” in Paragraph 1 can best be replaced by “ ”.
A. priceless B. unusual
C. perfect D. useless
2.The second paragraph is mainly about .
A. how the GPS works B. the history of the GPS
C. the applications of the GPS D. some problems with the GPS
3.According to the text, the GPS .
A. has a history of over 100 years
B. became popular during the Cold War
C. relies on the satellites circling the earth
D. was available first during space exploration
4.What does the author think of the GPS?
A. It is not always reliable
B. It has a lot of uses in many fields
C. It makes our life more peaceful
D. It will soon go out of fashion

When was the last time you saw some dolphins at an aquarium? Was it fun to watch? Do you think the dolphins enjoyed it? A new film shows just exactly where some of these dolphins come from. And it isn't pleasant.
The Cove is a documentary film with a lot of blood…dolphin blood. It's all about dolphin drive hunting, which is a method of hunting dolphins that fishermen use. They use boats to drive the dolphins into a bay or onto a beach. Once there, the dolphins are prevented from escaping and are then killed in the water with knives or spears.
The dolphins are mostly hunted for their meat, but some are captured and ended up in dolphinariums, including the world famous Sea World parks. This form of dolphin killing takes place in many places around the world. There are dolphin drive hunts in the Solomon Islands, Peru and the Faroe Islands.
The Cove focuses on a particular dolphin hunt near the town of Taiji in Japan.
Every year, more than 2,000 dolphins are driven into a cove near the town and killed. The documentary film is directed by former National Geographic photographer Louis Psihoyos, and was made secretly throughout 2007 using underwater microphones, and a hidden camera. Also appearing in the film is Ric O’ Barry, the director of saving Japan dolphins, and also a marine mammal expert. He trained dolphins for the popular 1960s TV series Flipper. He is praised for having started the dolphin entertainment industry but has spent most of his life fighting against it.
So what do the people of Taiji think about it? Many feel that they are being unfairly selected out. The town of Taiji has a 400-year history of whale and dolphin hunting and its fishermen only catch about 20% of Japan's yearly dolphin quota(份额).
Masashi Nishimura, manager of the Japan Fisheries Association's International section said,“ I don't think it's a big topic here,” he said, “as long as the killing is humane（人道的）, dolphins are like other animals to us.”
But for many people, dolphins are special. They are clearly highly intelligent mammals and they often form strong bonds of friendship with humans. Primates such as chimpanzees, gorillas and orangutans are all protected species. Should these levels of protection be extended to marine mammals too? Many believe they should.
1.Which of the following is not TRUE according to the passage?
A.Fishermen use boats to drive the dolphins into a bay.
B.There are dolphin drive hunts in the Solomon Island.
C.Underwater microphones were used to make the film.
D.All the dolphins caught in Japan are sold for meat.
2.What is Masashi Nishimura’s attitude towards the killings?
A.Cold. B.Regretful.
C.Unfair D.unsupportive
3.What is the author’s purpose in writing the passage?
A.To introduce a documentary film The Cove.
B.To show how The Cove was made.
C.To encourage people to protect dolphins.
D.To describe what is happening to dolphins.

When was the last time you did something really fun with one of your parents—just the two of you?
Parents who take their young children to music, swimming and art classes often stop arranging such activities once their kids are older and in school all day. But it doesn’t have to be that way. Doing something enjoyable with your kids just might make you look at each other in a whole new way, especially if you do it through a class or an event. When parent and child become students together, it puts them on the same level, at least for a while.
“I really like parents to come to class with their kids—they start sharing things and talking about what they’re doing and what they like,” said art teacher Pyper Dixon.
However, finding something new in common is a big choice for them, especially when kids get involved in sports and other after-school activities. But it’s possible to learn a new skill or hobby together.
That’s certainly true of Lauren, 11, of Silver Spring, who is in Dixon’s class with her father, Dennis. “I was just going to drop her off,” Dennis said, “but Dixon persuaded me to stay.”
Now Lauren gets to nag her father about doing his art homework. “He always leaves it to the last minute,” she said. “But then he’ll turn around to do amazing drawings,” she added, “We have different styles of drawing, so it’s interesting to talk it over with him.”
Without the Saturday morning art class, Dennis said, he would be reading the paper, and Lauren would be on her own in her room or on the computer. But they talk more now. “I can’t think of an experience where you communicate with your kid so closely,” he said.
1.The author raises the question at the beginning to_______.
A．expect an answer
B．criticize some parents
C．introduce the topic
D．support his argument
2.What does Dixon think is the benefit of parent and child studying art together?
A．They will become equal.
B．They will communicate more.
C．The child will learn art much better.
D．The parent will learn something new.
3.The underlined word “nag” in the text probably means _______.
A．urge B．help C．miss D．teach
4.We can learn from the text that_______.
A．Lauren used to talk a lot with her father
B．Dennis enjoys studying art with Lauren
C．Lauren dislikes her father’s drawings
D．Dennis likes playing computer games

Last week when I was sitting in my office, I heard an elderly lady talking on the phone about her husband. Her husband’s name was Ed. He dropped her off for her doctor’s appointment and was going to park the car and wait for her. She was so upset that she started to cry. I knew I should take action.
The lady told me her name was Helen and she called the restaurant she and her husband were going to have lunch at after her appointment to see if he was waiting for her there. She explained that she thought her husband parked the car in the parking lot and waited for her in the car but she didn’t find him there so she returned to see if he entered the medical building, but Ed was not there either. She regretted making her husband park the car alone since some signs of Alzheimer’ (早老性痴呆症)had appeared in his behavior. I asked a few nurses to help look for Ed inside and out side the medical building according to Helen’s description. Then I offered to drive Helen to the restaurant to see if Ed was waiting for her there.
On arriving at the parking lot of the restaurant, Helen began to search for Ed’s car but she failed, which suggested Ed wasn’t there. We decided to have a talk with the manager before we returned to the hospital. On our way to the manager’s office, I received a call from a nurse, who said they had found Ed. What a relief(安慰)! But we still needed to go on searching since he forgot where he parked his car! Fortunately, we didn’t have much difficulty finding it.
As I waved goodbye to the couple, I thought, “This is true love in life. The love is not romantic but it stays with us all the time.”
1. What did Helen do after she found Ed was missing?
A. She called the police. B. She turned to the author.
C. She called the restaurant. D. She searched for him everywhere.
2. We learn from this passage that Ed .
A. went to the restaurant himself B. might have developed Alzheimer’s
C. visited his friend in the hospital D. worried about his wife very much
3. When did the author know that Ed was found?
A. After the author and Helen returned from the restaurant.
B. While the author and Helen were on their way to the restaurant.
C. Before the author and Helen found the manager of the restaurant.
D. When the author and Helen arrived at the parking lot of the restaurant.
