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 |

About 809 primary school pupils from Southwest China’s quake-hit Sichuan Province arrived in eastern Shandong Province on a special train to attend classes there. The pupils, all from Leigu Township, Beichuan County, a badly-hit area in Sichuan, will study for about two months in schools in Shandong’s capital city of Jinan.
They have been arranged to study in four schools in Jinan and enjoy free schooling, food and accommodation. Each pupil would be given a monthly subsidy of 30 yuan. “To let them come to Jinan is not only for study, but also for recovery from the quake trauma (精神创伤).” said Zou Shiping, Jinan’s vice mayor. In Mingzhu Primary School in Jinan, a wall of pictures became a special way for the local pupils to welcome their friends from the quake zone. Dormitories were also specially decorated for them.
“This is the best meal that I have had for a long time.” a student from Wenchuan said after her first breakfast in the new place. Huang Zujie, Jinan Education Bureau’s deputy director, said, “We will let the children feel just as they are in their hometown.” Huang said the schools had invited chefs of Sichuan cuisine to let the pupils taste their familiar hometown meals. A second group of about 500 middle school students from Sichuan will soon come to Jinan for classes.Where did those 809 primary school pupils arrive?
A.Hebei Province. | B.Qing Dao. | C.Jinan | D.Beichuan County. |

We are living in a wonderful age, which has become wonderful largely through the scientific discoveries and inventions. There are always new discoveries and new knowledge ahead in every field. For example, much is yet to be discovered in electricity. Weather forecasting is an important area today. Science is doing much in the control of diseases.
Science is a never-ending road for us to go along. Every field gives changes to the person who wants to make science his life work.
Science is also a method of thinking, which can teach us how to solve problems and help us to arrive at the truth. The men and women who will be the scientists of tomorrow are in our colleges, factories and farms today. We are all potential scientists.

As we all know, robots are playing an important role in our daily life at present. Now South Korean schoolchildren see robot teachers in the classroom at an elementary school in Seoul. Robot teachers – who never get angry or make sarcastic (讽刺) remarks--- have been a hit with pupils during a pilot project in some South Korean schools, a government report said Thursday.
Elementary school children responded favourably to the robotic teachers, the Ministry of Knowledge Economy said, citing a survey by educational researchers.
English-teaching robots were sent to three provincial schools for eight weeks starting in late December.
And programmable electronic devices looking like robots, which teach math, science and art, were used in 10 Seoul schools for five weeks from November.
The researchers found that the English-teaching robots helped raise interest in the language and boosted the confidence of students.
“Tele-presence (远程呈现)” robots are controlled remotely by an English teacher and are equipped with a microphone and video camera. Autonomous units use voice-recognition software to interact with children .
The government has expressed interest in robots to give rural school children more learning opportunities.
“The machines spurred creativity and had a positive influence on the attitude of students,” a ministry official told Yonhap news agency.
Officials in charge of the project are working to improve the quality of robot teaching and iron out glitches (小故障)before any decision to expand (扩大) their use.What’s the writer’s purpose of writing the passage?
A.To show South Korean schoolchildren don’t like their teachers |
B.To prove robot teachers are better than real teachers. |
C.To tell us the government will forbid using robot teachers in the future. |
D.To show us a piece of news about robot teachers. |
According to the passage, the schoolchildren’s attitude to the robot teacher is _____ .

The underlined word “spurred” can be replaced by “______”.
A.encouraged | B.prevented | C.damaged | D.cut |
A British train station has put up a no kissing sign to stop lovers going full stream ahead with their over-loving goodbyes. Rail users have been told: if you want to get up to that kind of business, do it in the car park.
The sign has gone up at the drop-off point (下车区) at Warrington Bank Quay station in the town of Warrington, between Liverpool and Manchester in northwest England. A man in a hat and a woman with a curly-looking hair show people they must not indulge (沉迷于) in full –on lip- locking.
A similar sign, this time permitting kissing , has been put up elsewhere in a zone where smooching (拥吻) is considered acceptable. “We have not banned kissing in the station,” said a spokesman for operators Virgin Rail. “But we have put the sign at the drop-off point because it is not a very big area and it often gets busy with lots of traffic.”
The sign is a light-hearted way of getting people to move on quickly. “If people wish to spend a little more time with their loved ones before they leave, then should park in the short-stay car park nearby.”
The busy station links the town with the major cities London, Birmingham, Glasgow, Edinburgh, Liverpool and Manchester.
However, one station is trying to rescue love from the tracks, High Wycombe, northwest of London, is having none of it and is actively urging travelers to enjoy love. “Kissing is welcome here! We would never dream of banning kissing,” says a poster of a cartoon couple embracing, framed by a pink heart.
“Railway stations are romantic places,” insisted Kirsteen Roberston from Chiltern Railways. “So our passengers are more than welcome to share a kiss in our stations.”Why is a no kissing sign put up at the drop-off point?
A.Because the space is limited and people are often crowded. |
B.Because the station wants to ban kissing in the area. |
C.Because people can easily see the sign. |
D.Because the trains have been put off many times. |
The underlined words “that kind of business” mean “_______”
A.buying and selling | B.kissing each other |
C.parking cars | D.buying tickets |
From the passage we know that Chilten Railways _____ .
A.bans kissing in the station | B.plays films of kissing in the station |
C.encourages kissing in the station | D.bans travelers to see films of kissing |
