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.
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.

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.

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.

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.

C．He also made snake robots for search, rescue and exploration.

Have you ever heard the story of the four-minute mile? 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 in1954.
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 does not know how to swim, falls in deep waters? They drown. If an animal who has not learned swimming could escape by swimming, why not you? Because you believe you will drown while the animal does not.
Have you ever wondered why the letters are organized in a particular order on hour keyboard? You might have thought it is to increase the typing speed. Most people never question it. But the fact is that this system was developed to reduce the typing speed at a time when typewriter parts would jam if the operator typed too fast.
These three cases show the power of our beliefs. There is no other more powerful directing force in human behavior than belief. Your beliefs have the power to create and to destroy. A belief delivers a direct command to your nervous system.
I used a snake in my workshops for children to show them how unrealistic some of their beliefs are. Students of a school in India, said snakes were slippery, slimy (黏糊糊的) and poisonous. After doing an exercise for changing beliefs, they handled my snake and found it to be dry and clean. They also remembered that only three types of poisonous snakes exist in India.
Did this story end the way you thought? Review your beliefs now and find out which ones you need to change.

B
What should you think about when trying to find your career? You are probably better at some school subjects than others. These may show strengths that you can use in your work. A boy who is good at mathematics can use that in an engineering career. A girl who spells well and likes English may be good at office work. So it is important to know the subjects you do well in at school. On the other hand, you may not have any specially strong subjects but your records show a general satisfactory standard. Although not all subjects can be used directly in a job, they may have indirect value. A knowledge of history is not required for most jobs but if history is one of your good subjects you will have learned to remember facts and details. This is an ability that can be useful in many jobs.
Your school may have taught you skills, such as typing or technical drawing, which you can use in your work. You may be good at metalwork or cookery and look for a job where you can improve these skills. If you have had a part-time job on Saturdays or in the summer, think what you gained from it. If nothing else, you may have learned how to get to work on time, to follow instructions and to get on with older workers. You may have learned to give correct change in a shop, for example. Just as important, you may become interested in a particular industry or career you see from the inside in a part-time job.
Facing your weak points is also part of knowing yourself. You may be all thumbs when you handle tools; perhaps you are a poor speller or cannot add up a column of figures. It is better to face any weakness than to pretend they do not exist. Your school record, for instance, may not be too good, yet it is an important part of your background. You should not be apologetic about it but instead recognize that you will have a chance of a fresh start at work.
46. We can infer from the first paragraph that ________.
A.learning better at school shows power in your job
B.the better you are at school subjects, the more helpful they are in your career.
C.learning each subject well is an ability in many jobs.
D.we should think about how to find our career

C. regret not having worked harder at school
D. have an opportunity of a new beginning in his future work
48. All the subjects may have direct value for job hunting except _________.
A. mathematics B. English C. history D. technical drawing
49. The underlined phrase “be all thumbs” (in Paragraph 3) probably means “_________”.
A. heavy- handed B. the best C. important D. skilled

A. The relationship between school performance and career
B. how to get a job

As a seasoned magician from Taiwan, Liu is popular worldwide for his magic shows. Countries he has performed in include the United States, Japan, South Korea and the UK.
Witnessing something impossible happen right before your eyes is the root of people’s love for magic.
Liu is known for his interaction with his audiences. He has a unique understanding of showmanship(演出技巧)。

Invented in Turkey and patented by Nanopool, a German company, the spray-on liquid glass might become one of the most useful inventions in the field of nanotechnology. The product was tested at the Saarbrücken Institute for New Materials.
It is worth mentioning that the invention is transparent and non-poisonous. The liquid glass can protect any type of surface from damages caused by water, UV radiation, dirt, heat, and bacterial infections. Besides, it is flexible and breathable, which means that the liquid glass can be applied on plants and seeds as well. Researchers found that the spray greatly increases the resistance of plants to bacteria-caused diseases. The trials also showed that the sprayed seeds grew faster.
Depending on the type of surface that is to be covered, researchers can add water or ethanol to the spray. Scientists say that their latest invention has a long-lasting anti-bacterial effect. The spray produces a coating that is just 100nm thick. Trials by food processing plants in Germany have concluded that foods covered with the glass can store longer than those stored in normal condition.
According to Neil McClelland, UK project manager with Nanopool, due to its capabilities, the spray-on liquid glass can become one of the most useful inventions around the world, ending up being used by a lot of industries that will cover their products. At present, the invention is being used by a train company and a hotel chain in the UK, as well as a hamburger chain in Germany that are carrying out tests of the liquid glass for various uses.
The spray-on liquid glass was also tested in a Lancashire hospital, where it showed “very promising” results, being used to cover medical equipment and bandages. The invention could be also used on clothing, because it cannot be seen by the naked eye, thus clothes could become stain resistant. Due to its unique characteristics, the liquid glass can be used to cover bathrooms, sinks and many other surfaces in the home. According to the researchers, the spay-on glass can last for a year. It is expected to hit the DIY stores across Britain at a price of 5 pounds.
