Nowadays, children watch television for long hours. They often spend evenings watching their favorite programs on TV. Sometimes they might stay up late to watch TV. Their addiction to television results in their not having time to play or do exercise. They should go outside with friends or spend time reading books. Moreover, watching television too much is harmful to their eyesight.
Researchers claim that attention deficit disorders in children are a result of watching too much television. They say that watching television leads to a developmental disorder in the part of the brain which is responsible for language skills. Children who watch television more and read less have greater difficulty paying attention and concentrating. Children that spend long hours watching television are more likely to be affected by attention deficit disorders.
Television is one form of media which is used to show all kinds of products. Watching too much television can lead to early exposure to a wide variety of things. Television advertisements may cause children to behave incorrectly or damage themselves. Advertisements about fast food, cold drinks or other such products that are not good for children’s health can have a bad effect on them. Some TV shows and films also affect how children think and behave.
Studies in psychology have shown that certain programs can have a long-lasting effect on children’s minds. Horror scenes and other frightening shows can have a negative effect on the minds of children watching them.
Television is a means of recreation but watching it too often is harmful to children’s physical and mental health. You need to help you children deep a balance of everything in life.

举一反三
Too many people wander through life like sleepwalkers. Each day they follow familiar routines, never asking, ＂What am I doing with my life?＂and they don＇t know what they＇re doing because they lack goals.
Goal-setting is a focus of the will to move in a certain direction. Begin with a clear conception of what you want. Write down your goals and date them---putting them into words clarifies them. Rather than concentrating on objects to acquire and possess, focus on fulfilling your desires to do, to produce, to contribute to goal-setting that yields the true sense of satisfaction we all need.
It’s important to visualize(想象)yourself accomplishing your goal. While losers visualize the penalties(不利) of failure, winners visualize the rewards of success. I’ve seen it among athletes, statistics contrasting air and highway safety, but it made no difference. I had read too many articles describing crash scenes and imagined these scenes vividly. I had programmed myself, without realizing it ,to stay off planes.
Then one summer I had the opportunity to fly on a private plane with friends to a resort; I didn’t want to miss out on a great vacation. So I spent two weeks imagining a smooth flight on a beautiful sunny day and an easy landing.
When the day arrived, I was eager to go . To everyone＇s surprise, I got on the plane and I loved every minute of it , and I still use the techniques I employed that day.
小题1:According to the passage, if you want to be successful ,the first thing for you to do is to .
| A．find the right methods | B．be careful about everything |
| C．know your ability | D．have a clear goal |
| A．he didn’t know air travel is safer than highway travel |
| B．he couldn’t imagine himself accomplishing his goal |
| C．he read too much about plane crashes and tried to avoid flying |
| D．he wanted to take a private plane instead of a public one |
| A．Defining Your Goal | B．Visualizing Reward of Success |
| C．Overcoming the Fear of Air Travel | D．Sleepwalking Through life |
Sonny opened his eyes wide, “Do you mean next time when I’m entering for the 60-metre race I should wish that Billy, Tony and Sandy would all fall asleep halfway?”
I was shocked, “But the tortoise didn’t wish that the hare would fall asleep!”
“He must have wished that,” Sonny said, “Otherwise how could he be so foolish as to race with the hare? He knew very well the hare ran a hundred times faster than he himself did.”
“He didn’t have such a wish,” I insisted. “He won the race by perseverance (坚忍不拔的), by pushing on steadily.”
Sonny thought a while. “That’s a lie,” he said. “He won it because he was lucky. If the hare hadn’t happened to fall asleep, the tortoise would never have won the race. He could be as steady as you like, or a hundred times steadier, but he’d never have won the race. That’s for sure.”
I gave up. Today’s children are not like what we used to be. They’re just hopeless.
小题1:The writer argued (辩论)with his son because ______________.
| A．he liked tortoises while his son liked hares |
| B．they disagreed about whether the tortoise was foolish |

| D．he liked the story of the hare and the tortoise while his son didn’t. |
| A．won the race by his own hard working |
| B．took a risk (冒险) by agreeing to run a race |
| C．was not given a fair chance in the race |
| D．in fact did win the race luckily |
| A．boys who were unknown to Sonny’s father |
| B．boys who Sonny has run races with before |
| C．boys who Sonny has never raced with before |
| D．boys who Sonny did not expect to race with again |

“To provide enough power, we need certain methods with high energy density（密度）”，said Jae Kwon, assistant professor of electrical and computer engineering at MU．“The radioisotope（放射性同位素） battery can provide power density that is much higher than chemical batteries．”
Kwon and his research team have been working on building a small nuclear battery, presently the size and thickness of a penny, intended to power various micro / nanoelectromechanical systems （M/NEMS）．Although nuclear batteries can cause concerns, Kwon said they are safe．
“People hear the word ‘nuclear’ and think of something very dangerous,” he said, “However, nuclear power sources have already been safely powering a variety of devices, such as pace-makers, space satellites and underwater systems．”
His new idea is not only in the battery’s size, but also in its semiconductor（半导体）．Kwon’s battery uses a liquid semiconductor rather than a solid semiconductor．
“The key part of using a radioactive battery is that when you harvest the energy, part of the radiation energy can damage the lattice structure（晶体结构） of the solid semiconductor,” Kwon said, “By using a liquid semiconductor, we believe we can minimize that problem．”
Together with J．David Robertson, chemistry professor and associate director of the MU Research Reactor, Kwon is working to build and test the battery．In the future, they hope to increase the battery’s power, shrink its size and try with various other materials．Kwon said that battery could be thinner than the thickness of human hair．
小题1:Jae Kwon gave examples in Paragraph 4_________．
| A．to show chemical batteries are widely applied． |
| B．to introduce nuclear batteries can be safely used． |
| C．to describe a nuclear-powered system． |
| D．to introduce various energy sources． |
| A．uses a solid semiconductor | B．will soon replace the present ones． |
| C．could be extremely thin | D．has passed the final test． |
| A．science news report | B．book review |
| C．newspaper ad | D．science fiction |
But what are stem cells? As we know, most cells in our bodies are designed to serve specific purposes – for example, a liver cell develops to work in the liver and cannot become a heart cell. But stem cells are different. They are very young, and in the laboratory scientists can grow them into different types of cell.
Claudia Castillo needed a new windpipe after getting a serious disease. Scientists from the University of Bristol in the UK took a donor windpipe, or trachea, from someone who had recently died. They used strong chemicals to remove the donor’s cells, leaving a tissue scaffold(组织支架). This was refilled with cells from Ms Castillo’s windpipe, and stem cells from her bone. After four days the cells had grown sufficiently for the windpipe to be transplanted into Ms Castillo.
Currently, transplant patients have to take drugs for the rest of their lives to prevent their bodies rejecting the new organs. These drugs can have bad side-effects, and do not always prevent rejection. But by using Ms Castillo’s own cells, doctors were able to trick her body into thinking the new windpipe was her own organ. Five months on, Claudia Castillo is in perfect health.
This ground-breaking procedure could be used in other transplant operations in the future. Scientists also believe stem cells might be used to treat Parkinson"s disease, Alzheimer"s disease, heart disease, stroke, arthritis, diabetes, burns and so on.
However, stem cell research is extremely controversial. The most effective stem cells do not come from adults but from embryos created in laboratories and which are just a few days old. Many people have religious or ethical objections to growing embryos, even if they can be used to cure diseases.
小题1:This transplant is considered the greatest medical breakthrough because _________.
| A．this is the first organ transplant in the whole world |
| B．the patient is in perfect health after the operation |
| C．it is the first success with new stem cell technology |
| D．the stem cells are from an embryo developed in a lab |
| A．they are grown in the lab only |
| B．they can grow into different types of cell |
| C．they are designed for a specific purpose |
| D．they can work in the liver not in the heart |
| A．How Claudia survived in the operation |
| B．How to remove the cells from the donor’s organ |
| C．Why stem cells are needed in the transplant |
| D．How the windpipe is transplanted |
| A．Human bodies always reject transplanted organs even with their own cells |
| B．The donor’s cells had to be removed because they were unhealthy |
| C．The transplanted organ was refilled with the stem cells only |
| D．Claudia will not have to take drugs to prevent rejection. |
| A．controversial | B．confident |
| C．conservative (保守的) | D．critical |
“The map says you have to turn when you see a large stone with a red circle,” said one of them.
“What do we do after the turn?” I asked 26 .
“It says we should see a tree. We are 27 to turn 20 meters north of it and dig.
We got there and dug. We had 28 at first digging but we got better and worked very 29 . My trousers were dirty but I kept digging 30 I hit something. It was a large metal box. We 31 the lock and looked inside. There was a letter. It read:
“The lesson you have learned will be very 32 . If you put as much 33 in anything you do as you did in finding the 34 , you will have found the key to making over 20 million dollars.”
This was a trick from my parents. I thought I would never forget this 35 birthday present.
