Motorists who used to listen to the radio or their favorite tunes on CDs may have a new way to entertain themselves, after engineers in Japan developed a musical road surface.
A team from the Hokkaido Industrial Research Institute has built a number of“melody roads,”which use cars as tuning forks to play music as they travel.
The concept works by using grooves(凹槽).They are cut at very specific intervals in the road surface. The melody road uses the spaces between to create different notes.
Depending on how far apart the grooves are, a car moving over them will produce a series of high or low notes, and designers are able to create a distinct tune.
Paten documents for the design describe it as notches “formed in a road surface so as to play a melody without producing simple sound or rhythm and reproduce melody-like tones”.
There are three musical strips in central and northern Japan—one of which plays the tune of a Japanese pop song. Reports say the system was invented by Shizuo Shinoda. He scraped some markings into a road with a bulldozer before driving over them and found that they helped to produce all kinds of tones.
The optimal speed for melody road is 44kph,but people say it is not always easy to get the intended sound.
“You need to keep the car windows closed to hear well,”wrote one Japanese blogger.“Driving too fast will sound like playing fast forward, while driving around 12mph［20km/h］has a slow-motion effect, making you almost car-sick.”According to the passage, melody roads use to create different notes.

We can learn from the passage that the highness of notes is depended on .
| A．how far the grooves are | B．how big the grooves are |
| C．the number of the grooves | D．the speed of the car |

In order to hear the music well, you have to .
| A．drive very fast | B．drive slowly |
| C．open the windows wide | D．keep the windows closed |
What’s the best title of the passage?

Work is a very important part of life in the United States. When the early Protestant immigrants came to this country, they brought the idea that work was the way to God and heaven. This attitude, the Protestant Work Ethic(道德规范), still influences America today. Work is not only important for economic benefits, the salary, but also for social and psychological needs, the feeling of doing something for the good of the society. Americans spend most of their lives working, being productive. For most Americans, their work defines them: they are what they do. What happens then, when a person can no longer work? Almost all Americans stop working at age sixty-five or seventy and retire. Because work is such an important part of life in this culture, retirement can be very difficult. Retirees often feel that they are useless and unproductive. Of course, some people are happy to retire; but leaving one’s job, whatever it is, is a difficult change, even for those who look forward to retiring. Many retirees do not know how to use their time or they feel lost without their jobs. Retirements can also bring financial problems. Many people rely on Social Security checks every month. During their working years, employees contribute a certain percentage of their salaries to the government. Each employer also gives a certain percentage to the government. When people retire, they receive this money as income. These checks do not provide enough money to live on, however, because prices are increasing very rapidly. Senior citizens, those over sixty-five, have to have savings in the bank or other retirement plans to make ends meet. The rate of inflation is forcing prices higher each year; Social Security checks alone cannot cover these growing expenses. The government offers some assistance, Medicare(health care)and welfare(general assistance), but many senior citizens have to change their life styles after retirement. They have to spend carefully to be sure that they can afford to buy food, fuel and other necessities.
Of course, many senior citizens are happy with retirement. They have time to spend with their families or enjoy their hobbies. Some continue to work part time, others do volunteer work. Some, like those in the Retired Business Executives Association, even help young people to get started in new business. Many retired citizens also belong to “Golden Age” groups. These organizations plan trips and social events. There are many chances for retirees.
American society is only beginning to be concerned about the special physical and emotional needs of its senior citizens. The government is taking steps to ease the problem of limited income. They are building new housing, offering discounts in stores and museums and on buses, and providing other services such as free courses, food service, and help with housework. Retired citizens are a rapidly growing percentage of the population. This part of the population is very important and we must meet their needs. After all, every citizen will be a senior citizen some day.The author believes that work first became important to Americans because of _______.

With double duty as the mother of the household, she was exhausted, so that the youngest was often the target of anger and annoyance. Bad words, such as “you little fool” and the like, served as a daily meal for the youngest.

“Congratulations, young man! Your test results are incredible! You are really a great and talented young man. ”Words from the board of examiners became the discovery of a new side of himself that was not known in advance. Voice kept echoing in his mind, such as “I, the great man, am in the shower”, “The great man washes his face”, “The talented young man again brushes his teeth” and so on.

Cleverness is a gift while kindness is a choice. Gifts are easy – they’re given after all. Choices can be hard.
I got the idea to start Amazon 16 years ago. I came across the fact that the Internet usage was growing at 2,300 percent per year. I’d never seen or heard of anything that grew that fast, and the idea of building an online bookstore with millions of titles was very exciting to me. I had just turned 30 years old, and I’d been married for a year. I told my wife MacKenzie that I wanted to quit my job and go to do this crazy thing that probably wouldn’t work since most start-ups don’t, and I wasn’t sure what to expect. MacKenzie told me I should go for it. As a young boy, I’d been a garage inventor. I’d always wanted to be an inventor, and she wanted me to follow my passion.
I was working at a financial firm in New York City with a bunch of very smart people, and I had a brilliant boss that I much admired. I went to my boss and told him I wanted to start a company selling books on the Internet. He took me on a long walk in Central Park, listened carefully to me, and finally said, “That sounds like a really good idea, but it would be an even better idea for someone who didn’t already have a good job.” That logic made some sense to me, and he convinced me to think about it for 48 hours before making a final decision. Seen in that light, it really was a difficult choice, but finally, I decided I had to give it a shot. I didn’t think I’d regret trying and failing. And I suspected I would always be haunted by a decision not to try at all.
After much consideration, I took the less safe path to follow my passion, and I’m proud of that choice. For all of us, in the end, we are our choices.What inspired the author with the idea of building an online bookstore?
