A Robot Fish has been developed by National University of Singapore’s researchers from the Department of Electrical & Computer Engineering．This robot fish has movements which have been inspired by the movements of the carp（鲤鱼）．
There are various purposes that it can be used for．It can help in underwater archaeology （考古学）．For example, it can enter a sunken city where human divers cannot enter．Just like a fish , it can also look at all the comers of particular wreckage．This robot can also be used for general purposes such as detection of leakages in a pipeline or for laying down communication cables across oceans．It also has possible military uses．
In order to copy carp movements, Mr．Fan studied the movements of the fish for around 3 months．He studied all the different movements of carp using different cameras and then converted these movements mathematically to transfer this data to the robot using many actuators（驱动器）．
Professor Xu commented on the robot that the current models that copy fish movements are capable only of 2D movements which limits their capability as they are not able to dive into water．He said that his model is the first model with 3D movements which allows it to dive as well as float with the help of its fins, just as a normal fish would do．Hence, this fish model robot has much greater movement capability．It would be much harder for enemies to detect as compared to traditional ones when used for military purposes．
The researches want to make their robot fish even smaller, more realistic while adding more sensors such as GPS and video camera to it．This will improve its autonomous 3D movement．They are also planning to test the fish by giving it more difficult tasks such as detecting various objects．
The author gave an example in paragraph 2 _____．

A．to introduce the Robot Fish can help in underwater archaeology

B．to show the Robot Fish can be used for general purposes

C．to show the Robot Fish can lay down communication cables across oceans

D．to tell us the Robot Fish has possible military uses

Which is NOT true about the 3D Robot Fish?

A．It is capable of diving into water．

B．It cannot dive into water．

C．It can float using its fins．

D．It is difficult to detect．

What' s the main idea of the last paragraph?

A．The researchers will give the robot more difficult tasks．

B．The researches want to make their robot smaller．

C．The researchers are going to test the robot．

D．The researches plan to improve the robot．

Which of the following would be the best title for the text?

A．First Robot Fish with Autonomous 3D Movement used widely

B．First Robot Fish with Autonomous 3D Movement treading the ocean

C．First Robot Fish with Autonomous 3D Movement created in Singapore

D．First Robot Fish with Autonomous 3D Movement's general purposes

Parking has long been a major headache for drivers in Shanghai. The Transportation Department is mapping out a new plan for the city’s parking system. There are one million cars on the road in Shanghai but only enough public parking space to provide room for 15 percent of these vehicles. It is no wonder that local drivers get so worried trying to find a place to park.
The city is seeing a rise in private car owners. In March, the city sent out 2,000 private car licenses, the highest number of licenses ever sent out in a month. And prices rose to 14,600 yuan, 500 more than in February. Industry experts say this suggests that local people have a strong, active interest in buying cars.
By the year 2020, the number of automobiles in Shanghai will probably reach two million. If one parking lot is for each car, then a lot of parking space should be built for these vehicles.
Downtown Shanghai is most short of parking space. However, experts point out that simply building more parking lots in downtown areas is not practical and doesn’t provide an ideal solution. The idea of “ Park & Ride” system has been suggested. This means that drivers can leave their vehicles in car parks nearby subway or bus stations and ride public transport to go downtown. Based on this idea, the city will limit the number of parking lots in downtown areas and demand higher parking fees but build more parking areas near main subway and bus stops.
72.The underlined phrase “ mapping out ” in the first paragraph means __________.
A. making B. arguing C. controlling D. inspiring
73. About __________ drivers can find places to park their cars in Shanghai now.
A. 850,000 B. 1,000,000 C. 150,000 D. 2,000,000
74. What does the second paragraph mainly tell us ?
A. The city sent out more private licenses in February.
B. Less and less people bought cars in March.
C. The city sent out less private licenses in March.
D. More and more people are going to buy cars.
75. According to the idea of a “ Park & Ride ” system, the city will __________.
A. send out more private car licenses
B. build more parking lots near bus stops
C. encourage people to buy more cars
D. build more parking areas in downtown

When you take a walk in any city, you often see a lot of people walking dogs. It is still true that a dog is the most useful and faithful animal in the world, but the reason why people keep a dog has changed. In the old days people used to train dogs to protect(保护) themselves against attacks by other beasts. Later they came to realize that a dog was not only useful for protection but willing to obey his master. For example, when people used dogs for hunting, the dogs would not eat what was caught without permission.
These days people in the city need not protect themselves against attacks from animals. Why do they keep dogs, then? Some people keep dogs to protect themselves from robbery（抢劫）. But the most important reason is for companionship. For a child, a dog is a best friend when there are no friends to play with. For young couples, a dog is their child when they have no children. For old couples, a dog is also their child when their natural children have grown up. So the main reason why people keep dogs has changed from protection to friendship.

There’re five people at our table, including myself. I’ve already learnt a great deal about them in the short time we’ve been at sea, although we rarely meet except at meal times.
First of all, there’s Dr Stone. He’s a man of about sixty five, with gray hair and a friendly face. He gave up his work a short while ago and is now traveling round the world before he retires to some quiet country village. As a young man, he served for many years as a doctor in the army and visited many countries. He’s told us a lot about the city to which we are going.
Then there’s “Grandmother”. I call her that because her name escapes me.

Naturally she is very excited at the thought of seeing her again, and her three grandchildren, whom she has never seen.
Then there’s a man I don’t care for very much, an engineer by the name of Barlow. He has been on leave in England and is now returning to his work in Singapore.
The other person who sits at our table is Mrs. Hunt. I’ve found out hardly anything about her. She’s extremely quiet and rarely talks, except to consult（咨询）the doctor about children’s various illness. She’s on her way to join her husband in India.

When I was sixteen years old, I made my first visit to the United States. It wasn’t the first time I had been abroad. Like most English children, I learned French at school. I had often been to France, so I was used to speaking a foreign language to people who didn’t understand French. But when I went to America, I was really looking forward to having a nice and easy holiday without any language problems.
How wrong I was! The misunderstandings began at the airport. I was looking for a public telephone to give my American friend Daisy a call and tell her that I had arrived. A friendly old man saw me looking lost and asked if he could help me.
"Yes, "I said, "I want to give my friend a ring. "
"Well, that's nice, "he said. "Are you getting married? But aren't you a bit young?"
"Who is talking about marriage?" I replied. "I only want to give my friend a ring to tell her I've arrived. Can you tell me where there's a phone box?"
"Oh! "he said. "There's a phone downstairs. "
When at last we met, Daisy explained the misunderstanding to me.
"Don't worry, "she said to me. "I had so many difficulties at first. There are lots of words which the Americans use differently in meaning from the British. You' ll soon get used to all the funny things they say. Most of the time, British and American people understand each other!"
