US military is attempting to develop a new style “insect robot” to replace the human soldier to go wherever he can’t. The greatest trouble this project has fallen across is how to enable the robot to fly freely like an insect， said an official of the Pentagon(五角大楼).
The Pentagon is seeking for the cooperation with scientists in hope of developing a new technique by which people can control the insect’s flight direction and pass on the information its eyes or other organs catch through the equipment set in its body， the official said.
It is thus designed that a tiny controlling chip will be equipped in an insect’s body when it is in chrysalis(蛹). As the insect grows， the cut made when fixing in the chip will be recovered. The chip will exist in forever. Scientists believe this won’t influence the insect， sound growth or the functions of internal organs.
The terminal target of the project is to set up a global system， in which the insect robots will be stationed in all parts of the world and stick to their posts till a new instruction is received. At that time the military can receive from all over the world clear image information within about 5 meters of the insects and that of a special target within 100 meters.
Years ago， Defense Advanced Research Projects Agency of US DOD(国防部) spent $3,000,000 carrying out a plan for training bees to detect landmines. But， no new progress has so far been made.
“According to the scientists， there is still enormous difficulty in technology in turning it into reality， such as the insects reproduction(繁殖)， their adaptation to the surroundings and temperature and so on. However， this project is really challenging. If successful， it is equal to making countless small drone(无人机)，”said the official of DOD.According to the description of the passage， what is an insect robot like？
| A．An insect made of a certain metal. |
| B．A robot looking like an insect. |
| C．An insect with a chip in its body. |
| D．A tiny flying robot. |
As for the design that an insect robot can receive and send information， how do you infer(推测) it works？
| A．There must be a controlling chip well connected with the insect’s brain. |
| B．The insect’s eyes and other organs must be replaced by some special equipment. |
| C．All the insect’s concerned organs must be controlled by a chip. |

“Dining out”, or “eating out”, is a phrase people use in Britain when they eat in a restaurant or a pub. Eating out is more popular in Britain today than ever before.
However, eating out can be expensive. Restaurants are normally more expensive than pubs, though many pubs serve very good, simple food. As British people don’t dine out every night of the week, eating in a restaurant is often seen as a special occasion. When going for the first date, or if celebrating an anniversary or a birthday, many people like to go to a restaurant. People often eat in a restaurant before going to the cinema or the theatre.
As in all cultures, there are many rules of etiquette (礼节)surrounding food and eating, and nowhere is this more pronounced than when eating in a smart restaurant. People are almost always expected to eat with a knife and fork and these should be held in the correct hand and used in the correct way. It is also impolite to have your elbows on the dining table when you are eating.
There’re many such “unspoken” rules — they are normally only important when eating in a very elegant and expensive restaurant, and vary slightly from restaurant to restaurant and place to place. A recent nationwide survey showed that there was a divide in manners between the north and south of Britain — the “worst” manners were in Scotland and the northeast, and the “best” in Wales and the southeast! However, this survey was almost certainly conducted by someone in the southeast, so it may not be entirely fair.
Naturally, restaurants vary greatly in quality and price. However, almost all British cities have a vast range of food and cooking styles to choose from as well as traditional British food,. from the very cheap to the very expensive — French, Italian, Indian, Greek, Thai, Japanese and many more. In fact, when asked what their favorite food is, many British people say an Indian curry (咖喱菜）rather than any other dish!
As well as dining in a restaurant, when people are too tired to cook after work they often get a “takeaway”. This means they order from a takeaway or takeout restaurant by phone, then go to collect it and take it home to eat. Many takeout restaurants also deliver to your house. While you can normally find a takeout restaurant for almost any cuisine, the most popular are Italian, Indian and Chinese — and all you have to do is to open the door, pay and eat!What can be concluded from the first two paragraphs?
| A．The British spend more eating out than cooking at home. |
| B．The British pay great attention to eating in a restaurant. |
| C．The British often dine out when celebrating festivals. |
| D．People tend to eat in a restaurant after watching a movie. |
The underlined word “pronounced” in Paragraph 3 probably means “_____”.
| A．polite | B．expensive | C．strange | D．obvious |
According to the passage, which of the following statements is true?
| A．There exist great differences of rules in different restaurants. |
| B．People from Wales and southeast Britain are the most polite. |
| C．Your order in a takeout restaurant can be sent to your home. |
| D．Traditional British food is seldom served in British restaurants. |
What does the passage mainly talk about?
| A．Restaurant culture in Britain. | B．Table manners in Britain. |
| C．Different restaurants in Britain. | D．Traditional and foreign foods in Britain. |

It is a truth universally acknowledged that a single man in possession of a good fortune must be in want of a wife.
However little known the feelings or views of such a man may be on his first entering a neighborhood, this truth is so well fixed in the minds of the surrounding families that he is considered the rightful property of someone or other of their daughters.
“My dear Mr. Bennet,” said his lady to him one day. “have you heard that Netherfield Park is let at last?” Mr. Bennet replied that he had not.
“But it is, ” returned she, “for Mrs. Long has just been here, and she told me all about it.”
Mr. Bennet made no answer.
“Do you not want to know who has taken it?” cried his wife impatiently.
“You want to tell me, and I have no objection to hearing it.”
This was invitation enough.
“Why, my dear, you must know, Mrs. Long says that Netherfield is taken by a young man of large fortune from the north of England; that he came down on Monday in a chaise to see the place, and was so much delighted with it, that he agreed with Mr. Morris immediately; that he is to take possession before Michaelmas, and some of his servants are to be in the house by the end of next week.”
“What is his name?”
“Bingley.”
“Is he married or single?”
“Oh! Single, my dear, to be sure! A single man of large fortune; four or five thousand a year. What a fine thing for our girls!”
How so? How can it affect them?
“My dear Mr. Bennet,” replied his wife, “how can you be so tiresome! You must know that I am thinking of his marrying one of them.”
“Is that his design in settling here?”
“Design! Nonsense, how can you talk so! But it is very likely that he may fall in love with one of them, and therefore you must visit him as soon as he comes.”
“I see no occasion for that. You and the girls may go, or you may send them by themselves, which perhaps will be still better, for as you are as beautiful as any of them. Mr. Bingley may like you the best of the party. ”The sentence “… a single man in possession of a good fortune must be in want of a wife” means that ______.

Where on Earth are you? Navigators (导航员) use lines of latitude and lines of longitude to locate places. Lines of latitude run east and west around Earth. On a map or globe, these lines appear as running sideways or horizontally. Lines of longitude run north and south around Earth. These lines go up and down or vertically on a map or globe. These lines create an imaginary graph paper on the Earth. They make it possible to find an absolute, or exact, location on Earth. They even allow us to give an absolute location to a place out in the middle of the ocean.
Lines of latitude tell us how far north or south of the Equator we are. Sailors have used primitive navigation tools, like astrolabes, since ancient times. The astrolabe uses the sun and stars to find an approximate location. Using such tools, they have been able to approximate their distance from the equator. Although their instruments may not have been the high quality we have now, they were incredibly accurate (精确) for their time.
Lines of longitude tell us how far east or west of the prime meridian (本初子午线) we are. Sailors constantly looked for new ways to increase their navigation skills. Still, it wasn’t until the 18th century that they were able to measure degrees of longitude. They would have been very envious of the technology available to us today.
When we use lines of latitude and longitude together, we can get a very precise location. If we want to identify the absolute location of a point, we look where the latitude and longitude lines cross nearest to that point. We use the coordinates (坐标) for that point as its address. Many maps today include degrees of latitude and longitude.______ make it possible for people to find an exact place on Earth.
| A．Latitudes | B．Longitudes | C．Navigators | D．Sailors |
The second paragraph mainly talks about _______.
| A．the function of latitude | B．the use of the equator |
| C．the invention of astrolabe | D．the high quality instruments |
Why do maps include degrees of latitude and longitude?
| A．To help trade expeditions. | B．To locate a precise place. |
| C．To cross the lines of the nearest point. | D．To identify how far a place is. |
The best title for this passage is ____________.
| A．The map and the globe | B．Latitude and longitude |
| C．The equator and the prime meridian | D．Absolute coordinates |
