Since the 1970s, scientists have been searching for ways to link the brain with computers. Brain-computer interface(BCI) technology could help people with disabilities send commands to machines.
Recently, two researchers, Jose Millan and Michele Tavella from the Federal Polytechnic school in Lausanne, Switzerland, demonstrated(展示)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 band. He could even talk as he watched the vehicle and guided it with his thoughts.
“our brain has billions of nerve ceils. These send signals through the spinal cord (脊髓)to the muscles to give us the ability to move. But spinal cord injuries or other conditions can prevent these weak electrical signals from reaching the muscles,” Tavella says. “Our system allows disabled people to communicate with external world and also to control devices.”
The researchers designed a special cap for the user. This head cover picks up the signals from the scalp(头皮) and sends them to a computer. The computer interprets the signals and commands the motorized wheelchair. The wheelchair also has two cameras that identify 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 interprets brain signals and turns them into simple commands. “The practical possibilities that BCI technology offers to disabled people can be grouped in two categories: communication, and controlling devices. 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 benefit frotn. And the other is to guarantee that they can use the technology over long periods of time.

BCI is a technology that can________
A. help to update computer systems B. link the human brain with computers

A. make profits from them B. prove the technology useful to them

D
Mars was the first planet that humans attempted to get to. Since the 1960’s, scientists have been working to learn more information about the Mars’ past, We now know that Mars was once a warm, wet place with great oceans and deep rivers. We also know that about 3.7 billion years ago, all that water disappeared when the planet lost its air. But why did the atmosphere on Mars change so greatly?
NASA had launched the MAVEN spacecraft in the hope of answering that very question. MAVEN will study the remains of Mars’ air and help scientists figure out what became of the rest of it.
The spacecraft was launched on Monday, November 18, 2013, from Cape Canaveral, Florida. The trip to Mars takes about 10 months. and MAVEN is scheduled to go into orbit in September 2014. It is the first spacecraft created with the purpose of studying Mars’ atmosphere. Its wings measures 37.5 feet not quite the length of a school bus, and it weighs 1991 pounds about the same amount as a small car. MAVEN is equipped with eight different tools to measure and study the planet’s atmosphere. To collect information, it will fly in orbit as fast as 3278 miles per hour, and as slow as 93 miles per hour.
Once it arrived at Mars, MAVEN will have plenty of company. The spacecraft Curiosity is still walking around the planet’s rocky surface, studying the geology, chemistry and possible biology there. NASA currently has a number of spacecrafts getting unique views of Mars with powerful cameras and telescopes. These missions are all slow, steady steps forward to discover Mars secret past. While the results may not be revealed for some time, an exciting exploration is on the way.
1.We can learn from the first paragraph that________
A.all the scientists wanted to live on Mars
B.people have had a better knowledge of Mars nowadays
C.spaceships have been sent up to Mars since 1960s
D.all the water on Mars has been gone for ten billion years
2.The MAVEN spacecraft has been launched with the purpose of________
A.analyzing the change of the atmosphere on Mars
B.assisting Curiosity in studying the surface of Mars.
C. analyzing what is contained in Mars’ air
D.checking whether water still exists on Mars
3.It can be inferred from, the text that__________.
A.many different tasks will be given to MAVEN when it lands on Mars
B.many spacecrafts are working around Mars to study its water
C.more wonderful things about Mars will be found in the future
D.more spacecraft will be sent up to help Curiosity
4.What is the best title of this text?
A.A new finding on Mars
B.A new spacecraft sent to Mars
C.The rapid development of Mars
D.The great change of the Mars’ atmosphere

For more than twenty years scientists have been searching for signs of life on other planets. Most of these searches have been done over the radio. The hope is that someone in outer space may be trying to get in touch with us. Scientists also have sent radio and television messages on spaceships traveling through space, on the chance that someone may be receptive to such messages.
Scientists are using powerful radio telescope to listen to signals from about 1,000 stars, all within 100 light years of earth. In addition, they will scan (扫视) the entire sky to “listen” for radio messages from more distant stars. Using a computer, they will be able to monitor more than eight channels at one time. Scientists are looking for any signal that stands out from the background noise.
Of the 200 billion stars in the Milky Way galaxy, scientists find that five percent are like our sun. Perhaps half of them have a planet like earth. Such a planet would be a reasonable distance from the star for temperatures to be right for the evolution (进化) of life. Based on the inhabitable (that can be lived in) planets in our galaxy, most scientists agree that chances are likely that one or more of these planets support some life.
However, many scientists wonder whether intelligent life exists on other planets. Some believe that twenty years of searching without any intelligible messages shows that no one is out there. They say that the evolution of intelligence comparable to ours is unlikely.
Other scientists believe that our search hasn’t been long enough to rule out the possibility that intelligent life exists in our galaxy. Although our sun family in only about five billion years old, our galaxy is about 20 billions years old. In that time, some scientists think it is likely that civilizations are much more advanced than ours. Perhaps these civilizations send us no signals; perhaps we have not recognized the signals they have sent us. If we hope to find intelligent life, these scientists believe that we have to keep looking.
1.According to the passage, how many planets in our galaxy might be inhabitable?
A. 15 billion. B. 10 billion.
C. 5 billion D. 200 billion
2.The first paragraph in this passage is mainly about ________.
A. why scientists are looking for signs of life on other planets
B. how scientists are looking for signs of life on other planets
C. where scientists are looking for signs of life on other planets
D. when scientists are looking for signs of life on other planets
3.The underlined word “monitor” in the passage means “________”.
A. find B. follow
C. form D. check
4.Which of these statements is True based on the information in the passage?
A. Scientists are tying different ways to find signs of life on other planets.
B. Most scientists believe that there is intelligent life on other planets.
C. The earth is one of the oldest planets in our galaxy.
D. Scientists don’t believe that there might be life on other planets.
