Have you ever heard that we humans use only ten percent of our brains? This opinion holds a certain appeal because if it were true, then we could instantly become ten times more intelligent just by firing up that sleepy majority of the brain!
The idea that we use only a small part of the brain dates back to animal experiments in the 19th century. When scientists stimulated (刺激) a specific part of the brain, the animal moved its leg or tail. If a tiny part of the brain could do something so great, what was the use of the rest of the brain? Some scientists assumed that large parts of the brain were simply useless.
Then, in the early 20th century, scientists observed that stimulating certain parts of the brain had no physical effects. They named these seemingly useless parts of the brain the “silent cortex.” Today we know that in humans, much of the “silent cortex” is actually devoted to complex activities like language, learning, and imagining.
Brain scans have shown that different parts of the brain become much more active as we shift (切换) our attention and focus, but even as we sleep, many areas of the brain are extremely active. Would you be smarter if your entire brain constantly worked to maximum capacity (能力)? Interestingly enough, the opposite is probably true. The less brain activity you need to perform a given task, the more the brain as a whole is able to do.
1.Why does the opinion mentioned in paragraph l seem appealing?
A. People wish to become much smarter.
B. People believe it is scientific.
C. People know nothing about the brain.
D. People want to make little use of their brain.
2.What did scientists discover in their experiment in the 20th century?
A. The majority of the brain is sleeping.
B. Animals’ legs and tails have some connection with their brain.
C. Stimulation on some parts of the brain causes no physical reaction.
D. Certain parts of the brain are devoted to language and learning activities.
3.“Silent cortex” has proved to be______.
A. sensitive to stimulation
B. useful in complex activities
C. responsible for physical reaction
D. more active than the other parts of the brain
4.If you need less brain activity to perform a task, _______.
A. you will feel sleepy
B. you must shift your focus
C. you can use your brain to the fullest
D. you will be more productive

Have you ever heard of spring fever? When we have spring fever, are we really sick? Originally, yes. 1. But now people used it to mean a sudden increase of romantic feelings.
These days, we use “spring fever” to describe a restless feeling after the long, cold days of winter. 2. It is also a verb that means something happening or appearing quickly.
Imagine that you are resting in the chair when suddenly you see a mouse run across the floor. You spring into action! You jump from the chair and run after the mouse! 3. And it works! But when you tell your roommate that you caught a mouse in a trap, tears spring from her eyes. You feel badly, but she really should have told you about her pet mouse Charlie!
4. You say to her, “You can’t just spring that on me! I’ll need time to find another roommate!” But then you think that maybe it’s for the best. Every time you see her you feel guilty about Charlie. 5. She always expects you to buy her things: she wants you to spring for lunch, spring for movie tickets, and sometimes even spring for groceries.
So, when you spring for something, you pay for someone else.
A. Many people suffer a lot from it.
B. You roommate turns her back on you.
C. But the word “spring” is not just a season.
D. Spring fever used to refer to an actual illness.
E. Then your roommate is moving out tomorrow.
F. That night you spring a trap with some cheese in it.
G. And anyway, she does something that really annoys you.

Have you ever heard of the phrase “we just can’t communicate”? Most people communicate with the ability to read or write well. This might not be the case as you will soon find out.
How many times have you been to the doctor’s office and listened to an educated professional explain something to you that is just unintelligible. These people keep asking you, “Do you understand?” and sometimes out of embarrassment because you don’t want to look like stupid, you tell them. “Yes, I do understand.” This isn’t a good way to communicate, either.
How do we communicate in a positive way to get our points across? Ask the persons you are communicating with if they understand what you just said. In another case, if someone is talking to you, use the statement, “Just to make sure that I understand what you just said” and then repeat back your understanding of their conversation. Sometimes just asking a few simple questions and clarifying your understanding can bring great benefits to any communication.
In some countries like Japan, you might find them reading your body language more than the words you are communicating with. Sometimes just by the way someone stands or reacts to something you said, you can get a valuable insight to what the other person means in this conversation. Don’t forget, however, this could also lead to a misunderstanding. Again if you think someone is communicating with their body language, try not to assume that you know exactly what message they are trying to get across. Always ask them if they understand what you are talking about.
A person is responsible for what he says and to make sure that the other person completely understands the point he is trying to get across. Why not start using some of the simple skills in this article to help with your communication skill? You will start to see the benefits within a short period of time.
1.What does the underlined word “unintelligible” in paragraph 2 mean?
A. Hard to speak. B. Impossible to notice.

Have you ever heard the story of the four-minute miles? Many years ago, people believed that it was impossible for a human being to run a mile in less than four minutes until Roger Banister proved it wrong in 1954.
What happens if you put an animal in a pond? Any animal, big or small, will swim its way through. What happens when someone, who doesn’t know how to swim, falls in deep water? They drown.

Have you heard of snake robots? Scientists and doctors are already using tiny snakes that coil through the human body armed with sharp surgical tools to perform operations on hearts, prostate cancer, and other diseased organs. The snake robots that carry tiny cameras, scissors and forceps, and even more advanced sensors are being developed.
The next generation of the robots will be wireless, and will explore inside your body on their own--- not attached to any cables. For now, they are powered by cables that humans control. Experts say the day is coming when some robots will roam around the body on their own. But the experts in robotics say the new creations work best when they are designed for very specific tasks.
Howie Choset has been researching and building robots, particularly snake robots. He believes that his snake robot and others like it can help reduce medical costs by making complex surgery faster and easier. Choset says his new design is smaller and more flexible than earlier models.
The size of surgical robots allows surgeons to operate with far less damage to the body, helping the patient heal faster. Choset has also built larger snake robots designed for search and rescue, or just exploration. They can climb poles and trees and then look around through a camera in the head and slither through places that humans cannot reach.
“ We sent our snake robots into these caves in the Red Sea to look for evidence of ancient Egyptian ships,” he said. “ To me, archeology is like search and rescue, but everyone has been dead for 5,000 years.”
The doctors are very excited about the potential for surgical robots to do things that humans can’t do. The variety of sensors available for surgical robots keeps expanding. As they get smaller, maybe one day they will be able to test chemicals or blood in the body, or even the electrical connections in nerves.
1.What can we learn from the first paragraph?
A.The doctors carry out surgery using snake robots mainly for heart disease.
B.The doctors are very satisfied with the new snake robots during surgery.
C.Snake robots are completely free of human control today.
D.Other supplementary appliances will be added to snake robots.
2.Which of the following is true, according to the passage?
A.Snake robots are only used in the medical field.
B.Snake robots can reduce the patients’ medical costs.
C.Scientists are uncertain about the prospects for snake robots.
D.Scientists are forced to spend a lot of time researching snake robots.
3.How can snake robots work best, according to the passage?
A.When they carry tiny cameras, scissors and forceps.
B.When they are operated by experienced doctors.
C.When they are given a wireless function.
D.When they are designed for particular tasks.
4.Why do we know about Howie Choset, according to the passage?
A.He thought snake robots of different sizes can be used for different types of surgery.
B.He thought patients’ pain had been slightly reduced with the help of snake robots.
