Since the 1970s, scientists have been searching for ways to connect the brain with computers. Braincomputer interface(BCI) technology could help people with disabilities send commands to machines.
Recently, two scientists, Jose Millan and Michele Tavella from the Federal Polytehnic School in Lausanne, Switzerland, show a small robotic wheelchair directed by a person’s thoughts.
In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right hand. He could even talk as he watched the vehicle and guided it with his thoughts.
“Our brain has billions of body cells(細(xì)胞). These send signals through the spinal cord(脊髓) to the body part to give us the ability to move. But spinal cord injuries(脊柱受傷) or other conditions can prevent these weak electrical signals from reaching the body part.” Tavella says. “Our system allows disabled people to communicate with outer world and also to control machines.”
The scientists designed a special cap for the user. This head cover picks up the signals from the scalp(頭皮) and sends them to a computer. The computer finds meanings of the signals and commands the wheelchair with an engine. The wheelchair also has two cameras that tell objects in its path. They help the computer react to commands from the brain.
Prof. Millan , the team leader, says scientists keep improving the computer software that finds meanings of brain signals and turns them into simple commands.” The practical possibilities that BCI technology offers to disabled people can be grouped in two kinds: communication, and controlling objects. One example is this wheelchair.”
He says his team has set two goals. One is testing with real patients, so as to prove that this is a technology they can get advantages from. And the other is sure that they can use the technology for long.
小題1:BCI is a technology that can________.
A．help to make computer systems more modern
B．connect the human brain with computers
C．help the disabled to be healthier
D．control a person’s thoughts
小題2:Which of the following shows the path of the signals described in Paragraph 5?
A．scalp→computer→cap→wheelchair
B．computer→cap→scalp→wheelchair

D．cap→computer→scalp→wheelchair
小題3:The team will test with real patients to_________.
A．make money from them
B．prove the technology useful to them
C．make them live longer
D．learn about their physical condition
小題4:Which of the following would be the best title for the text?

What is color? Why do some of the things around us look red, some green, others blue?
Colors are really made by reflected(反射)light(光). We see color because most of the things reflect light. Something is red, because it reflects most of the red light. In the same way, if something is green, it reflects most of the green light. If something reflects all light, it is white. If it doesn‘t reflect any light, it is black.
Some of the light is reflected and some is taken in(吸收)and turned into(變成)heat.The darker the colour is, the less light is reflected, the more light is taken in. So dark-colored(深色的)clothes are warmer in the sun than light-colored(淺色的) clothes.
小題1:When something reflects light, we can_______.
A．see its colorB．see its heat　　
C．not see its colorD．see nothing
小題2:Something looks white because it reflects______.
A．some lightB．no lightC．a(chǎn)ll lightD．most light
小題3:The dark-colored clothes are warm because______is taken in(吸收).

In one way, it may be thought that failure（失敗）is a part of life. In another, failure may be regarded as a step towards success.
The "spider-story" is often told as an example of this. Robert Bruce, leader of the Scots in the 13th century, was hiding in a hole on a hill from the English. He watched a spider(蜘蛛) making a web. Bruce is said to have got confidence from this and to have gone on to beat the English. Edison, too, the inventor of the light bulb(電燈泡) , made hundreds of models that failed before he found the right way to make one.
So what? First, always think about your failure. What caused it? Were you in high spir¬it then? What can you change so that things will go right the next time?
Second, is the goal(目標(biāo)) you are trying to reach the right one? Try to do some thinking about what your real goals may be. Think about this question: "If I am successful in this, where will it get me?" This may help to prevent failure in the things you shouldn't be doing anyway.
The third thing to remember about failure is that it's a part of life. Learn to "live with yourself” even though you may have failed. Remember, "You can't win them all. “
小題1:Robert Bruce was mentioned in the passage to show that        .
A．people who fail are not lonely

As we know, it is not easy to build a satellite(衛(wèi)星). Building a traditional satellite usually takes years. The costs can be as high as $250 million or more. Most members of the design teams have worked in the field for a long time. They hold advanced degrees(學(xué)歷) in math, science, or engineering.

But things are changing. High costs, unusual educational needs and long start-up times are no longer an obstacle(障礙) to space exploration. The scientists have developed a new type of tiny, inexpensive earth-orbiting(軌道) satellite.
So far, college students have built and launched(發(fā)射) several cube-shaped satellites, or CubeSats. At least 15 more are ready to go. Those already in orbit take pictures, collect information and send it back to the earth, just as regular satellites do.
But you might not even have to wait until you get to college to start designing and building your own satellite. A new program called KatySat aims to get teenagers to take part in. When kids understand what satellites can do, the kinds of ideas they’ll come up with may be countless.
Education isn’t the only aim of CubeSats because these tiny, technology-filled boxes are  inexpensive to build and can be put together quickly, they’re perfect for testing new technologies that might one day be used on major space tasks.
The biggest challenge now is to find ways to bring the satellites back to the earth after a year or two. Or space junk could gradually increase because CubeSats become more popular.
Nowadays, college and high school students are getting a chance to learn what it takes to explore in space. Someday—perhaps a lot sooner that you imaging—you might get to design, build and launch your own satellite. If you do, you’re sure to have fun. And you might also get crazy about science for life.
小題1:Building a traditional satellite __________.
A. costs $250,000          
B. needs college students      
C. takes quite a long time
小題2:Compared with the traditional ones, the new satellites __________.
A. need long start-up times    
B. are cheap and small-sized   
C. collect more junk in orbit
小題3:The underlined word “countless” in Paragraph 4 probably means “__________”.
A. 無用的                   B. 無價(jià)值的             C. 無數(shù)的
小題4:According to the passage, which of the following is true?
A. CubeSats could possibly cause pollution in space.
B. Scientists designed CubeSats for kids to play with.
C. Students can’t design satellites without college education.
小題5:The purpose of the author writing the passage is __________.
A. to tell us that satellite technology can also be learned by kids
B. to show that high technology brings a big change in kids’ life
C. to tell us that kids must study hard to learn satellite technology

Our factories and homes burn coal and oil. Every year we have forest fires somewhere. Many scientists believe that the climate is changing.
The earth will perhaps be warmer by about 7 degrees centigrade. At the South Pole and the North Pole, the ice will melt (融化). The sea level (海平面) will rise by about 7meters. As a result, water will cover cities like London, Tokyo and New York. Some ports and towns along the coasts will disappear under water.
Some other scientists think that the dust, smoke and pollution from coal, wood and oil fires will block out the sunrays(紫外線). Then the earth will become colder and great sheets of ice will cover Europe and North America.
When chemicals in the air mix with rain, we have acid (酸) rain. Acid rain can bring us great harm. It destroys forests and kills life in lakes and rivers.
People are beginning to see how serious the problem is. They find it important to work with nature instead of against it. They are trying to save the earth in many different ways. But one of the most important things to do is to make people understand that saving the earth is saving ourselves.
小題1:Some scientists believe that          .               
A. the earth is growing warmer
B. we can find oil in our forests
C. we have to burn down the forests every year
小題2:Ice at the poles will          if the earth gets warmer.
A. cover cities like London and Tokyo
B. raise the sea level by 7 degrees
C. become water and make the sea level rise                
小題3:Acid rain          .
A. brings great changes in our climate
B. kills pests in lakes and forests
C. kills the fish in rivers and lakes                        
小題4:What can we learn from the third paragraph?
A. The dust together with pollution from coal, wood and oil fires will bring us more heat from the sun.
B. The sunrays will come more because of the dust and pollution from fires.
C. As a result of the dust and pollution from coal, wood and oil fires, the earth will become colder.

Mark began to introduce the guest speaker to the listeners, but then stopped for a while. He had forgotten her name.
Barbara hid her valuable things when she went on vacation. When she came back, she couldn’t remember where she’d put them.
Perhaps you’ve had such experiences like these. Most people have. But most of them haven’t realized that they have a memory problem. Neither do they know a simple but important fact: Memory can be improved. If you just accept that, the following will show you how.
First, relax. If you are over worried about something, you’ll forget it. If you keep telling yourself that your memory is bad, your mind will come to believe it and you won’t remember things. When you forget something, don’t follow up with saying like “Oh, my god! I always forget things! ” Such words will have a bad result on you and your memory.
But relaxing isn’t enough. To improve your memory, you’ll need to take an active role. Like your body, your memory can be made strong through exercise. Look for opportunities to exercise your memory. For example, if you’re learning a language, try to actively remember a lot of new words.
If you don’t take notice of things actively, you won’t remember them. So, you can make pictures of what you see in your mind every day. For example, don’t just put your keys down! If you want to find them again, make a mind picture of the place where you’re putting them.
小題1:The first two paragraphs just tell us ________.
A．examples of memory problems
B．Barbara was a very rich person
C．language problems of two persons
D．Mark often forgot his friends’ names
小題2:When you forget things, you ________.
A．must be too careless
B．must accept the fact
C．shouldn’t lose confidence in your memory
D．should keep telling yourself that your memory is bad

閱讀下列短文，根據(jù)短文中的信息完成文后表格。（每空一詞）
Have you had a headache during a test? Have you ever been so worried about something that you have a headache or even can’t sleep at night? If so, then you know what stress is. Stress is what you feel when you are worried about something. This worry in your mind can make your body feel bad. You may feel angry, sad, scared, or afraid——all of which can give you a stomachache or a headache.
However, there are different kinds of stress. Some kinds of stress are good and others are bad. Good stress might happen when you’re called to answer questions in class or when you have to give a speech. This kind of stress can help you to get things better done. For example, you may do a better job on your test if the stress pushes you to prepare better before the test.
On the other hand, bad stress can happen if the stress lasts too long. You may not feel well if your parents are fighting, if a family member is sick, if you’re having problems at school, or if anything else makes you unhappy every day. That kind of stress isn’t going to help you. And it can actually make you sick.
The best way to fight the stress is to have a balanced life. Make sure you keep your SELF in mind: Sleep, Exercise, Leisure（休閑）, and Food. If you get enough sleep and eat properly, and if you exercise and leave time for fun, you’ll probably feel less stressed.
