On an island there are exactly seven towns: T, U, V, W, X, Y and Z. All existing and planned roads on the island are two-way and run perfectly straight between one town and the next. All distances(距离；路程) by road are distances the main square of one town to the main square of another town. U is the same distance by road from T, V and W as Y is from X and Z. The following are of the now existing roads on the islands.
Road 1 goes from T to V via (经由) U.
Road 2 goes directly from U to W.
The triangle (三角形) road goes from X to Y, from Y on to Z, and from Z back to X. Any main square reached by two roads is an interchange (立交桥) between them, and there are no other interchanges between roads.

For as long as humans have lived on the earth, they have made use of various forms of communication. Generally, this expression of thoughts and feelings has been in the form of oral speech. When there is a spoken language problem, communication can be carried out through sign language, in which gestures stand for letters, words, and ideas. Tourists and people unable to hear or speak have often had to turn to this form of expression. When gestures describe words or ideas, they can often be used internationally(各国之间地). When used for spelling words however, where each gesture stands for a single letter, people must share the same written language. 
Body language sends ideas or thoughts by certain actions, either meaningfully or not. A wink(眨眼, 使眼色)can be a way of showing that the person is only joking. A nod means agreement, while shaking the head indicates disagreement.
Other forms of language can be found in Braille(a reading system of raised dots read with the fingertips used by the blind), signal flags, Morse code, and smoke signals. Road maps and picture signs also guide and warn people. While language is the most common form of communication, other systems and techniques also express human thoughts and feelings.

Scientists at Royal Holloway, University of London and Queen Mary, University of London have discovered that bees learn to fly the shortest possible route between flowers even if they discover the flowers in a different order. Bees are effectively solving the “traveling salesman problem”, and they are the first creatures found to do this. 
The traveling salesman must find the shortest route that allows him to visit all locations on his route. Computers solve it by comparing the length of all possible routes and choosing the shortest, and it can keep computers busy for days. However, bees solve it without computer assistance using a brain the size of grass seed. Dr. Nigel Raine, from the School of Biological Sciences at Royal Holloway explains, “Bees solve traveling salesman problems every day. They visit flowers at multiple locations and because bees use lots of energy to fly, they find a route which keeps flying to a minimum. ”
The team used the computer to control artificial flowers to test whether bees would follow a route defined by the order in which they discovered the flowers or if they would find the shortest route. After exploring the location of the flowers, bees quickly learned to fly the shortest route.
As well as improving our understanding of how bees move around the landscape pollinating(授粉)crops and wild flowers, this research, which is due to be published in The American Naturalist, has other applications. Our lifestyle relies on networks such as traffic on the roads, information flow on the Web and business supply chains. By understanding how bees can solve their problems with such a tiny brain, we can improve our management of these everyday networks without needing lots of computer time. Dr. Raine adds, “Despite their tiny brains, bees are capable of extraordinary feats of behavior. We need to understand how they can solve the traveling salesman problem without a computer. ” What would be the best title of the passage?
| A．Bees help salesmen travel |
| B．Tiny-brained bees solve a complex mathematical problem |
| C．How bees discover the flowers |
| D．How to solve the “traveling salesman problem” |
We may infer from the second paragraph that the “traveling salesman problem” .
| A．can be solved by a computer easily |
| B．can’t even be solved by a computer |
| C．can puzzle both people and computers |
| D．remains to be solved by scientists |
The main purpose of the last paragraph is to .
| A．provide further proof for the research |
| B．tell us how bees can fly the shortest route between flowers |
| C．tell us how the research about bees’ flying route was conducted |
| D．explain the importance of the research |
It can be concluded from the passage that .
| A．all creatures are smarter than computers |
| B．the research about bees’ flying route can be applied to many fields |
| C．our networks are more complex than bees’ ones |
| D．with the help of the computer we can find out how bees can solve the “traveling salesman problem” |
British writer John Bunyan was born at Elstow, Bedfordshire, England, in November, 1628. His father was a maker and mender of pots and kettles, and the son followed the same trade. Though he is usually called a tinker, Bunyan had a settled home and place of business. He had little schooling, and he describes his early surroundings as poor and mean. He became much interested in religions, but it was only after a tremendous spiritual conflict, lasting three or four years, that he found peace. His struggles are related with extraordinary vividness and intensity in his “Grace Abounding to the Chief of Sinners.” His writing began with a controversy against the Quakers (教友派), and shows from the first the command of a homely but vigorous style.
Like most working men at the time, Bunyan had a deep hatred for the corrupted, hypocritical rich who accumulated their wealth “by hook and by crook.” As a stout Puritan(清教徒), he had made a conscientious study of the Bible and firmly believed in salvation (拯救) through spiritual struggle.
Bunyan’s style was modeled after that of the English Bible. With his concrete and living language and carefully observed and vividly presented details, he made it possible for the reader of the least education to share the pleasure of reading his novel and to relive the experience of his characters.
Bunyan’s works include Grace Abounding to the Chief of Sinners (1666), The Life and Death of Mr. Badman (1680), The Holy War (1682) and The Pilgrim’s Progress (1684).
The Pilgrim’s Progress is the most successful religious allegory (寓言) in the English language. Its purpose is to urge people to observe Christian doctrines and seek salvation through constant struggle with their own weaknesses and all kinds of social evils. It is not only about something spiritual but also bears much relevance to the time. Its predominant metaphor — life as a journey — is simple and familiar. The objects that Christian meets are homely and commonplace, and the scenes presented are typical English ones, but throughout the allegory a spiritual significance is added to the commonplace details. Here the strange is combined with the familiar and the trivial joined to the divine, and, a rich imagination and a natural talent for storytelling also contribute to the success of the work which is at once entertaining and morally instructive.
“The Vanity Fair,” is an excerpt from The Pilgrim’s Progress. The story starts with a dream in which the author sees Christian the Pilgrim, with a heavy burden on his back, reading the Bible. When he learns from the book that the city in which he and his family live shall be burnt down in a fire, Christian tries to convince his family and his neighbors of the oncoming disaster and asks them to go with him in search of salvation, but most of them simply ignore him. So he starts off with a friend, Pliable. Pliable turns back after they stumble into a pit, the Slough of Despond. Christian struggles on by himself. Then he is misled by Mr. Wordly Wiseman and is brought back onto the right road by Mr. Evangelist. There he joins Faithful, a neighbor who has set out later but has made better progress. The two go on together through many adventures, including the great struggle with Apollyon, who claims them to be his subjects and refuse to accept their allegiance to God. After many other adventures they come to the Vanity Fair where both are arrested as alien agitators. They are tried and Faithful is condemned to death. Christian, however manages to escape and goes on his way, assisted by a new friend, Hopeful. Tired of the hard journey, they are tempted to take pleasant path and are then captured by Giant Despair. Finally they got away and reach the Celestial City, where they enjoy eternal life in the fellowship of the blessed.According to the passage, Bunyan hated the rich people mainly because ______.
| A．his father was making and mending pots and kettles |
| B．Bunyan had poor and mean early surroundings |
| C．the rich usually got their wealth in dishonest ways |

DNA left at a crime scene could be used in the future to build up a picture of an offender’s face, it was revealed tonight.
A first step towards genetic mugshots has been taken by researchers in the US who link specific DNA markers with face shape. To identify the genes, they focused on known mutations(突变) that cause changes of the face and head. Normal versions of these genes were found to influence individual features.For instance, one gene affected the lips, another the shape and configuration of bones around the eyes, and a third the appearance of the mid-face and skull. In total, 20 genes had “significant effects” on facial appearance.
Lead scientist Professor Mark Shriver, from Pennsylvania State University, said: “We use DNA to match to an individual or identify an individual, but you can get so much more from DNA. Currently we can’t go from DNA to a face, or from a face to DNA, but it should be possible.” The implications are far reaching, raising the possibility of creating a data bank of facial types based on genetic markers. DNA from a crime scene could then be used to produce a rough image of the face of an offender or victim. Such genetic mugshots may be more reliable than computer-generated “e-fits” based on witnesses’ recollections. Other uses of the technique might include proving the identity of fathers in paternity cases, or visualising our remote ancestors from fossil DNA.
The scientists wrote in the online journal Public Library of Science Genetics: “Such predictive modelling could be forensically useful; for example, DNA left at crime scenes could be tested and faces predicted in order to help to narrow the pool of potential suspects. Further, our methods could be used to predict the facial features of descendants, deceased ancestors, and even extinct human species. In addition, these methods could prove to be useful diagnostic tools.” The team developed a model which first established a range of physical face shapes from people of mixed West African and European ancestry from the US, Brazil and Cape Verde. Measurements were taken of thousands of point co-ordinates on grids placed over 3D images of the faces.
Statistical methods were then used to determine the relationship between facial differences and the effects of gender, ethnic ancestry and individual gene variants.The underlined word “mugshots” in the second paragraph most probably means _________.
| A．different faces | B．characteristics | C．pictures of faces | D．genders |
