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.

Some children are natural-born bosses. They have a strong need to make decisions, manage their environment, and lead rather than follow. Stephen Jackson, a Year One student, “operates under the theory of what’s mine is mine and what’s yours is mine,” says his mother. “The other day I bought two new Star Wars light sabres(剑). Later, I saw Stephen with the two new ones while his brother was using the beat-up ones.”
“Examine the extended family, and you’ll probably find a bossy grandparent, aunt, uncle or cousin in every generation. It’s an inheritable trait,” says Russell Barkley, a professor at the Medical University of South Carolina. Other children who may not be particularly bossy can gradually gain dominance(支配地位) when they sense their parents are weak, hesitant, or in disagreement with each other.
Whether it’s inborn nature or developed character at work, too much control in the hands of the young isn’t healthy for children or the family. Fear is at the root of a lot of bossy behaviour, says family psychologist John Taylor. Children, he says in his book From Defiance to Cooperation, “have secret feelings of weakness” and “a desire to feel safe.” It’s the parents’ role to provide that protection.
When a “boss child” doesn’t learn limits at home, the stage is set for a host of troubles outside the family. The overly willful and unbending child may have trouble obeying teachers or coaches, for example, or trouble keeping friends. It can be pretty lonely as the top dog if no one likes your bossy ways.
“I see more and more parents giving up their power,” says Barkley, who has studied bossy behaviour for more than 30 years. “They bend too far because they don’t want to be as strict as their own parents were. But they also feel less confident about their parenting skills. Their kids, in turn, feel more anxious.”

A．should give more power to their children
B．should be strict with their children

A．How bossy behaviour can be controlled.

Hospital emergency rooms treat injured fingers all the time. Without treatment，a bad cut can lead to permanent damage. But how should a person know when a bleeding cut is serious enough to require medical attention? We asked Dr. Martin Brown. Chairman of the department of emergency medicine at Inova Alexandria Hospital in Virginia.   
First，the medical term for a cut or tear in the skin is a laceration(严重划破，撕裂伤). Dr. Brown says the length is usually not as important as the depth. He says a long cut on a finger can likely be treated without a visit to a doctor if the wound is not very deep. “If you have a short but deep laceration where there’s been a structure underneath that's been damaged a tendon，a nerve，a blood vessel,”says Martin，“it may, in fact，need professional attention. ”
Some injuries —like a fingertip that gets cut off might even require surgery to repair. That requires a specialist to either file(锉平) down the bone or reattach the fingertip. More often，filing down the bone is what is done because reattaching a fingertip is often not successful.
How a wound bleeds can be a sign of how serious it is. Minor cuts usually produce what is known as venous(静脉)bleeding. This means the blood flows steadily from the injury. The bleeding will often stop when pressure is put on the wound. Dr. Brown says in most cases holding direct pressure with clean gauze or a cloth for four to five minutes should stop the bleeding. With a cut finger, holding the hand above the heart can reduce the loss of blood. But if a cut appears to be pumping blood out with some force，this may be a sign of arterial(动脉)bleeding. This kind of injury should be treated by a medical professional as soon as possible.
Even a cut that does not require medical attention must be kept clean to prevent infection. Small cuts should be cleaned gently with clean water. Use a washcloth to clean the area if the wound is dirty. Dr Brown says cuts should be covered with a clean, dry bandage.
