Today I attended a meeting holding in our school. At the meeting over forty model students praised. For our joy, Li Ding, the monitor of our class, who was among them. We all felt proud of her. Then the headmaster gave them a talk. He wanted us to learn these students and hoped that more and more students will be praised at the next school meeting. I was great encouraged and made up my mind to work harder. Next week there will be a English exam. I’ll try to get good marks.
The Great Wall of China, a wonder of the word, 1.(call) “The Ten Thousand Li Great Will” in China. It’s over 6,000 kilometers long, 6-7meters high2. 4 to 5 meters wide. At most places the Great Wall has a wide walkway3.snakes along the top. It is said that it’s the only man-made structure that can be seen from space. The Great Wall has a history of more than two thousand years. 4. was during the Qin Dynasty that the parts were joined up into one long wall. In ancient days it was difficult 5. (build) such a wall. Our forefathers carried, lifted and 6.(lay) big bricks and stones7.simple tools. Each brick and stone fits well, even 8.they didn’t have our modern machines!
Nowadays the Great Wall has become a place of interest. Every year people 9.all over the world come to visit it. Many of them have got to know the famous Chinese saying: “He who does not reach the Great Wall is not10.true man.”

The Science of Risk-Seeking
Sometimes We decide that a little unnecessary danger is worth it because when we weigh the risk and the reward, the risk seems worth tasking. 1.Some of us enjoy activities that would surprise and scare the rest of us. Why? Experts say it may have to do with how our brains work.
The reason why any of us take any risks at all might have to do with early humans. Risk-takers were better at hunting, fighting, or exploring.2.As the quality of Risk-taking was passed from on ration to the next, humans ended up with a sense of adventure and a tolerance for risk.
So why aren’t we all jumping out of airplanes then? Well, even 200,000 years ago, too much risk-taking could get one killed. A few daring survived, though, along with a few stay-in-the-cave types. As a result, humans developed a range of character types that still exists today. So maybe you love car racing, or maybe you hate it. 3.
No matter where you are on the risk-seeking range, scientists say that your willingness to take risks increases during your teenage years. 4.To help you do that, your brain increases your hunger for new experiences. New experiences often mean taking some risks, so your brain raises your tolerance for risk as well.
5.,for the risk-seekers a part of the brain related to pleasure becomes active, while for the rest of us, a part of the brain related to fear becomes active.
As experts continue to study the science of risk-seeking, we’ll continue to hit the mountains, the waves or the shallow end of the pool.
A. It all depends on your character.
B. Those are the risks you should jump to take.
C. Being better at those things meant a greater chance of survival.
D. Thus, these well-equipped people survived because they were the fittest.
E. This is when you start to move away from your family and into the bigger world.
F. However, we are not all using the same reference standard to weigh risks and rewards.
G. New brain research suggests our brains work differently when we face a nervous situation.
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 hand. He could even talk as he watched the vehicle and guided it with his thoughts.
"Our brain has billions of nerve cells. 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 from. And the other is to guarantee that they can use the technology over long periods of time.
1.BCI is a technology that can ________.
A. help to update computer systems
B. link the human brain with computers
C. help the disabled to recover
D. control a person's thoughts
2.How did Tavella operate the wheelchair in the laboratory?
A. By controlling his muscles.
B. By talking to the machine.
C. By moving his hand.
D. By using his mind.
3.Which of the following shows the path of the signals described in Paragraph 5?
A. scalp →computer→ cap→ wheelchair
B. computer →cap→ scalp→ wheelchair
C. scalp →cap→ computer →wheelchair
D. cap →computer →scalp →wheelchair
