In earliest times, men considered lightning to be one of the great mysteries of nature. Some ancient peoples believed that lightning and thunder were the weapons of the gods.
In reality, lightning is a flow of electricity formed high above the earth. A single flash of lightning 1.6 kilometres long has enough electricity to light one million light bulbs.
The American scientist and statesman, Benjamin Franklin, was the first to show the connection between electricity and lightning in 1752. In the same year he also built the first lightning rod (避雷针). This device protects buildings from being damaged by lightning.
Modern science has discovered that one stroke of lightning has a voltage (电压) of more than 15 million volts. A flash of lightning between a cloud and the earth may be as long as 13 kilometers, and travel at a speed of 30 million meters per second.
Scientists judge that there are about 2,000 million flashes of lightning per year. Lightning hits the Empire State Building in New York City 30 to 48 times a year. In the United States alone it kills an average of one person every day.
The safest place to be in case of an electrical storm is in a closed car. Outside, one should go to low ground and not get under a tree. Also, one should stay out of water and away from metal fences. Inside a house, people should avoid open doorways and windows and not touch wires or metal things.

I came to study in the United States a year ago. Yet I did not know the real American society until I was injured in a car accident because after the accident I had to see a doctor and go to court.
After the accident, my roommate called a doctor for me. I was very grateful and determined to repay him one day. But the next day, he asked me to pay him $200 for what he had done. I was astonished. He had good reason to charge me, he said. And if I wanted to collect money from the person who was responsible for my injury, I’d have to have a good lawyer. And only a good doctor can help me get a good lawyer .Now that he had helped me find a good doctor, it was only fair that I should pay him .But every time I went to see the doctor, I had to wait about 50 minutes. He would see two or three patients 
at the same time, and often stop treating one so as to see another. Yet he charged me $115 each time. The final examination report consisted of ten lines, and it cost me $215. My lawyer was all smiles the first time we met. But after that he avoided seeing me at all. He knew very well the other party was responsible for the 
accident, yet he hardly did anything. He simply waited to collect his money. He was so irresponsible that I decided to dismiss him. And he made me pay him $770.
Now I had to act as my own lawyer. Due to my inexperience, I told the insurance company the date I was leaving America. Knowing that ,they played for time,… and I left without getting a cent.
My experiences taught me two things about America: firstly, in a country like America money is everything. It is more important than friendship, honor or professional morality.

| A．be properly treated |
| B．talk with the person responsible for the accident |
| C．recover before he leaves America |
| D．eventually get the responsible party to pay for his injury |

Almost all theme park accidents can be prevented．Here, based on coverage of theme park safety, are some tips to help you and your family stay safe on your next visit.
If you are visiting with a child, take a moment to explain the ride to them, and tell them what they should do．They are depending upon you to keep them safe．Set a good example for them by following the rules of the park, and make sure that they know you expect them to follow those rules, too.
Tell them to stay seated, to hold the grab bar or put their hands in the laps, and not to stick their knees and feet outside a ride vehicle．Make them look to you for the okay to get on or off a ride, too．And never put a crying child on a ride．If your child starts to cry, let others pass you in line until your child is calmed．Or, gently exit the queue and find something more relaxing to do．
Young kids can’t keep an adult’s pace in a theme park．Let them take plenty of breaks.
“Kids get tired,” said TPI reader Matt Johnson, a father of four．“Tired kids make parents even more tired．And tired kids and parents may get hurt — physically and emotionally.” He advises that parents plan a mid-day break, perhaps a swim back at the hotel, to avoid mid-day heat and crowds．“You will see cranky families having a miserable time while you are refreshed and having a great evening.”The second paragraph tells readers that ________.

A recent study, while showing a generally positive attitude toward science, also suggests a widespread worry that it may be “running out of control”．This idea is dangerous．
Science can be a force for evil as well as for good．Its applications can be channeled either way, depending on our decisions．The decisions we make, personally or collectively, will determine the outcomes of science．But here is a real danger．Science is advancing so fast is so strongly influenced by businesses that we are likely to believe whatever decisions we come to will make little difference．And, rather than fighting for the best possible policies, we may step back and do nothing．
Some people go even further．They say that despite the moral and legal objections （反对）, whatever is scientifically possible will be done ——somewhere, sometime．They believe that science will get out of control in the end．This belief is dangerous too, because it a fuels sense of hopelessness and discourages them from making efforts to build a safer world．
In our interconnected world, the lack of agreement in and of the world of science can lead to the failure to control the use of science．Without a common understanding, the challenges of “controlling” science in this century will be really tough．Take human cloning for example．Despite the general agreement among scientists on its possible huge impact （影响） on traditional moral values, some countries still go ahead with the research and development of its related techniques．The outcomes are hard to predict．
Therefore, discussions on how science is applied should be extended far beyond scientific societies．Only through the united efforts of people with hope, can we be fully safe against the misuse of science and can science best serve mankind in the future．What can we conclude from the recent study?
| A．People think highly of science． |
| B．People hold mixed opinions about science． |
| C．Science is getting dangerously out of control． |
| D．Science is used for both good and bad purposes． |
According to the passage, what will happen if we hold that science is getting beyond control?
| A．The development of science will hopelessly slow down． |
| B．Businesses will have even greater influence on science． |
| C．The public will lose faith in bringing about a bright future． |
| D．People will work more actively to put science under control． |
The discussion should reach beyond scientific societies because __________．
| A．scientists have failed to predict the outcomes |
| B．the ties between different areas need strengthening |
| C．united efforts are necessary for the development of science |
| D．people need to work together to prevent the bad use of science |
What is the main idea of the passage?
| A．Science and its applications bring us many dangers． |
| B．The development of science mostly lies in people’s attitudes． |
| C．Mankind can largely take control of science with their efforts． |
| D．The future of science will be influenced by the dangerous ideas． |
