Many people in the world live in big cities, which are often dirty and difficult places to live. So, some cities will get bigger. They will also get higher, and lower, because people will begin to live under the ground as well as in tall buildings. Scientists also say that men can begin to live in cities under the sea, when there is not enough space on the land. Of course, these new cities will be very expensive, and difficult to build, but they are not impossible. Already, some countries are building places to live under the ground so their people can go there if there is a new war. There are underground cities in Switzerland（瑞士）and China, built by the government（政府）to help some of the people live during a great war.
But will people change if they live under the ground for a long time？For example some fish go blind if they live in the dark sea for a long time. People will not go blind, because there will be light underground, but they may change in some way. Scientists say that people who live in cities today are losing their senses of smell, touch and taste. They can’t smell the dirty air, they can’t taste the chemicals（化学制剂）in their food. These senses are not as strong as before, when people lived in the country and grew their own food. The city has changed that. What will the underground city change in everyone？

Look, this is the first plane in the world to be created using the new technology of “3D printing”. The airplane was built using only a computer—but it can fly at a speed of 100mph and has a two-meter wingspan.
It was produced using a special nylon laser printer that builds up something layer-by-layer. The parts were made separately and attached using a “snap fit” technique so the aircraft could be put together without tools in minutes.
No fasteners at all were used in the manufacture of the plane. Unmanned and electrically powered, the plane can travel in near silence and is also equipped with a small autopilot system. The special production process used is known as “laser sintering(激光烧结)”and allows the designers to create shapes and structures that would normally include costly manufacturing techniques. This technology allows a highly-tailored aircraft to be developed from your own design to first flight in days, while using traditional materials and techniques would take months. And because no tooling is required for manufacture, major changes to the shape and scale of the aircraft can be made with no extra cost.
Professor Jim Scanlon, who led the team, said, “The process allows the design team to revisit historical techniques and ideas that would have been too expensive using traditional manufacturing.” He added, “This form of structure is very firm and lightweight, but very complex. If it was manufactured traditionally it would require a large number of individually tailored parts that would have to be connected or fastened at great expense.”
The new printed plane is known as the Southampton University Laser Sintered Aircraft—or SULSA for short—and is part of a wider project using cutting-edge manufacturing techniques. The University of Southampton has been at the leading position of Unmanned Aerial Vehicle development since the early 1990s.

A. Revolutionary Breakthrough of 3D Printer
Scientists Create Aircraft with High Speed
C. New Designed Airplane with New Techniques.
D. The World’s first 3-D printed Airplane, SULSA
小题2:How could the plane work while flying?| A．It should be controlled by an autopilot system. | | B．It should be controlled by “laser sintering”. | | C．A pilot controls it using a remote control. | | D．A pilot with high techniques controlled it. |
小题3:This kind of plane has the following advantages EXCEPT ______.| A．it produces little noise while flying | | B．it is manufactured in quite a short time | | C．it only requires simple and cheap tools | | D．it needn’t extra cost if changes are made |
小题4:Professor Jim Scanlon believes they can _____ with their techniques.| A．produce firmer and lighter real planes easily | | B．connect and fasten tailor parts for real planes | | C．copy earlier planes to study their techniques | | D．find differences by studying the traditional ones |

More than 30 million kids buy school lunch each day. This year, many schools raised lunch prices to fight raising costs. Students pay about $2 a meal now. That is 27 cents more than last year. But they still get a good deal. The average cost for schools to produce one meal has gone up 30 cents, and is now $3.
So, how do schools neither make money nor lose money? To start, the government pays for a small part of the difference. Schools have to make up the rest. Peggy Eller, a leader of school nutrition (营养) service in Hudson, Wisconsin, said her district is cutting costs by using fewer paper products and serving smaller portion(份额). Well, portion control is one key to healthful eating!
The push for more healthful food has grown in recent years. One in five kids aged 6 to 19 is overweight. Being overweight can cause health problems. Many states passed laws that require schools to serve nutritious meals.
Since 2004, more than 90% of all U.S. Schools have removed the fat from lunches. Foods high in fat, salt and sugar have been replaced by low-fat milk, fresh fruits and vegetables. These new items on lunch menus have encouraged kids to change their eating habits. “It makes easier to try new things at home, “said Savanna Mackey, a Florida fifth-grader.
Students need healthful meals to grow strong and do well in school. “Rising prices won’t stand in the way,”says school nutritionist Jane Thornton. “We’ll just be more clever in how we do things.”
小题1:In the first paragraph, the author aims to tell us .| A．the large number of kids buying school lunch | | B．the average price of school lunch | | C．the school"s ways to deal with school lunch | | D．the fact of school lunch"s getting more expensive |
小题2:Many school districts raised lunch prices because .| A．there is less healthful food on the menus | | B．the cost of food has gone up | | C．kids often forget to bring lunch money | | D．some school dining-halls are serving smaller portions |
小题3:According to Paragraph 4, Savanna Mackey .| A．doesn"t like the new items on the lunch menus | | B．always enjoys foods like fresh and vegetables | | C．becomes interested in eating healthy food at home | | D．prefers eating at school to eating at home |
小题4:What can be inferred from the passage?| A．American schools solve the problem of high food prices by themselves. | | B．American schools are very concerned about their students’ health. | | C．Almost all schools are forced by the government to serve healthy foods. | | D．American childhood overweight is mainly caused by the present lunch foods. |

When we read books we seem to enter a new world. This new world can be similar to the one we are living in, or it can be very . Some stories are told they were true. Real people who live in a world do real things; in other words, the stories are about people just like us doing what we do. Other stories, such as the Harry Potter books, are not . They are characters and creatures that are very different from us and do things that would be for us.
But there is more to books and writing than this. If we think about it, even realistic writing is only . How can we tell the difference between what is real and what is not real? For example, when we read about Harry Potter, we seem to learn something about the real world. And when Harry studies magic at Hogwarts, he also learns more about his real life than . Reading, like writing, is an action. It is a way of . When we read or write something, we do much more than simple look at words on a page. We use our -- which is real-- and our imagination-- which is real in a different way --- to make the words come to life in our minds.
Both realism and fantasy(幻想) the imagination and the “magic” of reading and writing to make us think. When we read realistic, we have to imagine that the people we are reading about are just like us, even though we that we are real and they are . It sounds , but it works. When we read, we fill in missing information and about the causes and effects of what a character does. We help the writer by 52 that what we read is like real life. In a way, we are writing the book, too.
Most of us probably don’t think about what is going on in our when we are reading. We pick up a book and lose in a good story, eager to find out what will happen next. Knowing how we feel we read can help us become better readers, and it will help us discover more about the real magic of books.

Everyone may all have the experience of feeling anxious and stressed when having a rough day or having some troubles. Different people may choose different ways to deal with it, and for most people a break for a 10-minute walk may be quite useful.
Anyway, here is another way around: to get a piece of chewing gum, and chew it. According to a Swinburne University of Technology study, gum-chewing has been found to “relieve anxiety, improve alertness(机敏性) and reduce stress among individuals in a laboratory setting.”
Some may argue that a laboratory is not the same as an office. But check out the conditions of the study: individuals were monitored while performing “a group of ‘multi-tasking’ activities.” Doesn’t it sound like the situation in the office?
Here’s a summary of some of the study’s findings:
Gum chewers showed a reduction in anxiety as compared to non-gum chewers by nearly 17 percent during mild stress and nearly 10 percent in appropriate stress.
Gum chewers showed improvement in alertness over non-gum chewers by nearly 19 percent during mild stress and 8 percent in moderate stress.
Improved Performance: Chewing gum resulted in a big improvement in overall performance on multi-tasking activities.
Although these aren’t major improvements, every little bit works and chewing a piece of gum is a lot quicker and easier than slipping outside for a 10-minute walk. So, how does gum work this magic? In part it does so by lowering the level of cortisol(皮质醇)—a steroid(类固醇) hormone that is released in response to stress in your system.
A few words of advice before you reach for the gum: don’t crack your gum, and be sure to chew it with your mouth closed. In fact, I’d say keep the gum out of meetings, because it really looks impolite to others around you.
小题1:From the study in the text we know that_________________.| A．gum chewers may lack alertness | | B．gum chewers tend to be less stressed | | C．gum chewers can finish many jobs perfectly | | D．gum chewers can reduce their anxiety and anger easily |
小题2:How does gum work to reduce stress according to the text?| A．It works by improving alertness. | | B．It works by allowing a 10-minute walk. | | C．It works by reducing one’s level of cortisol. | | D．It works by being chewed in a laboratory setting. |
小题3:Which one may the author probably agree with?| A．People should chew gum with their mouths closed in a meeting. | | B．It is impolite to chew gum in a meeting with people around you. | | C．People can crack gum freely when meeting friends. | | D．People should be careful when chewing gum at home. |
小题4:What does the text mainly talk about?| A．How to chew gum. | B．How to relieve stress. | | C．Why people love chewing gum. | D．Chewing gum can relieve stress. |

What will people die of 100 years from now？ If you think that is not a simple question， you have not been paying attention to the revolution that is taking place in biotechnology(生物技术). With the help of new medicine， the human body will last a very long time. Death will come mainly from accidents， murder and war. Today"s leading killers， such as heart disease， cancer， and aging itself， will become distant memories.
In discussion of technological changes， the Internet gets most of the attention these days. But the change in medicine can be the real technological event of our times. How long can humans live？ Human brains were known to decide the final death. Cells are the basic units of all living things， and until recently， scientists were sure that the life of cells could not go much beyond 120 years because the basic materials of cells， such as those of brain cells， would not last forever. But the upper limits will be broken by new medicine. Sometime between 2050 and 2100， medicine will have advanced to the point at which every 10 years or so， people will be able to take medicine to repair their organs. The medicine， made up of the basic building materials of life， will build new brain cells， heart cells，and so on－in much the same way our bodies make new skin cells to take the place of old ones.
It is exciting to imaging that the advance in technology may be changing the most basic condition of human existence， but many technical problems still must be cleared up on the way to this wonderful future.
小题1:According to the passage， human death is now mainly caused by____ | A．diseases and aging | B．accidents and war | | C．accidents and aging | D．heart disease and war |
小题2:Humans may live longer in the future because ____ | A．heart disease will be far away from us | | B．human brains can decide the final death | | C．the basic materials of cells will last forever | | D．human organs can be repaired by new medicine |
小题3:We can learn from the passage that ____| A．human life will not last more than 120 years in the future | | B．humans have to take medicine to build new skin cells now | | C．much needs to be done before humans can have a longer life | | D．we have already solved the technical problems in building new cells |
