Henry Ford was the first person to build cars which were cheap,strong and fast.He was able to se11 millions of models because he could produce them in large numbers at a time;that is,he made a great many cars of exactly the same kind. Ford's father hoped that his son would become a farmer,but the young man did not like the idea and he went to Detroit where he worked as a mechanic .By the age of 29,in 1892,he had built his first car.However,the car made in this way,the famous "Model T" did not appear until 1908-----five years after Ford had started his great motor car factory.This car showed to be so well-known that it remained unchanged for twenty years.Since Ford's time,this way of producing cars in large numbers has become common in industry and has reduced the price of many goods which would otherwise be very expensive. The "Model T" was very famous _ . A) before 1908 B) between 1982 and 1908 C) before 1892 D) after 1908

To American visitors, Iceland is a very interesting country, partly because it is different in so many ways from what he or she is used to seeing at home. There are quite a few things that are not done, or that do not exist on the island - quite a few "No's". There is no pollution, for instance. No dogs are permitted in Reykjavik, the capital. There is no television on Thursdays or during the entire month of July, and only three hours of black-and-white TV the rest of the time. There is no hard liquor on Wednesdays and no beer at any time. There are no handguns; only one jail of thirty-five cells in the entire land - an admirable figure, even for a small country of 313,376 people. There is no army, air force or navy. There is no tipping for anything. There are no large stores open on Saturdays or Sundays. Since Iceland is situated just under the Arctic Circle, there is no darkness in summer and do daylight in winter. But thanks to Gulf Stream, the climate is rather mild, with temperatures ranging from 34 degrees Fahrenheit to 52 degrees in July. The rules on television, liquor, and guns are the result of governmental decision. But the absence of pollution is due in great part to the fact that Iceland gets its power from the enormous geyser and the thousands of hot springs that come out of the ground. They provide all the energy needed by the country. In fact, Iceland uses only 3 percent of all its available power. Iceland has been described as a democratic independent country where more fish are caught and more books published per person than anywhere else in the world. The Icelanders have always felt a particular love for literature. They composed their first works in the ninth and tenth centuries AD. These works were poems and tales about the kings, heroes, and heroines of Iceland and Norway. At first the stories were memorized and passed from generation to generation. The Icelanders have never stopped writing ever since. "Rather shoeless than bookless," they proudly say. There is no pollution in Iceland mainly because _ . A) Iceland uses only 3 percent of all its available power B) the Icelanders use hot water from the ground below as their energy C) it is located just under the Arctic Circle D) it is a democratic independent country

Q: Let's face it -- you're going to get a lot of well-intentioned advice from friends, parents and grandparents about your sleep. Some of this advice is going to be just wrong. Myth 1: Sleeping late on the weekends will make up for lost sleep during the week. Fact: Getting less than the amount of sleep that you need night after night accumulates over time and starts to create a "sleep debt". And like all debts, eventually you need to pay the price. The problem with waiting until the weekend to meet sleep needs is that in the meantime, you are paying the price of being less alert, feeling more moody, thinking slower and having less stimulation. Myth 2: A boring teacher (or warm room, full stomach, etc.) can put teens to sleep. Fact: If you are getting enough sleep on a regular basis, there is no teacher, math book or reading assignment in the world boring enough to make you fall asleep in class. There are basically two things that make people sleepy -- not getting enough sleep and not getting good quality sleep. The environment kids are in, including the room temperature, light level and entertainment value, may unmask underlying sleepiness, but the environment does not cause it! So if you are dozing off in class, don't blame it on bad teaching. Myth 3: Teenagers can pull an all-nighter to study and still be ready for the big test in the morning. Fact: Teenagers are much better off studying less and getting a good night's sleep. Research clearly shows that the ability to concentrate and learn new information, as well as to work efficiently, declines sharply after being awake for 15-16 hours, and continues to bottom out the longer you stay up. Plus, if the big test is at 8:00 am, the problem gets even worse. That's because morning time typically represents a low energy point in the body's normal 24-hour circadian rhythm, especially in teenagers. According to the passage, at 8:00 am a teenager will _ . A) feel more energetic after a night's sleep B) have a poor learning result C) have the least desire to learn D) be able to think in a quick way

(Question)
The history of the computer keyboard started way back in 1714, when the first typewriters were manufactured. Then, they looked more like sewing machines, since they were designed by Remington, which also used to manufacture sewing machines. They were not used for commercial purposes but to produce legal documents that were neat. 1868 was the year when Christoper Latham Scholes created the typewriter that is common today and was later mass marketed in 1877. Before the typewriter advanced to become the modern-day keyboard, there were a few developments that led to it. First there was the combination of the typewriter with the telegraph to create a teletype. Key punches were also created by the combination of the typewriter with punch card systems. The teletype was used to input data in the very first computers, and this is where the development of the computer keyboard started. How the teletype worked with the computer is that a card was inserted into the teletype. The keys would then be pressed in the teletype and a series of holes would be punched in the card. These were known as key punches, which would then be put into a card reader which analyzed the cards as data. This was in 1946, and in 1948 an electromagnetically controlled teletype was brought into operation for the binary automatic computer . There later came the video display terminal and electronic keyboards. When people typed, they would immediately see the results on the screen. This was in the 1970s, and people accepted the technology because it was user-friendly. There was no long process involved in getting something typed. The very first designs of these keyboards were big and heavy, and most did not come with the computer. This was later modified to a smaller size and different colours and designs, and that is the keyboard we use today. For what purpose were the first typewriters manufactured? A) To produce legal documents. B) To replace sewing machines. C) To record the results of research. D) To create the first computer keyboards.
