3.Friction is a force which opposes motion. Much of the energy supplied to a complicated machine with many moving parts is wasted in overcoming this opposition. The energy is converted into useless heat. The amount thus lost can be considerably reduced and the life of the machine prolonged by careful lubrication. This reduction improves the efficiency of the machine. Another way in which friction is reduced is to substitute roller or ball bearings for the earlier type of bearing, in which the surfaces in contact move by sliding. Bearings of these later types are used very extensively in many kinds of modern machinery.It must not be assumed, however, that friction is always a disadvantage. In many instances it is highly important. Belts are often used in conveying power from one machine to another. In the absence of friction, this could not be done. The driving wheel would not run the belt, neither would the belt run the wheel to driver. Without friction, then, belted machinery could not be used. Again in the case of all motor vehicles, friction is essential in the operation of the brake. Were there no friction, there could be no brake. But even this illustration does not give an adequate picture of the importance of friction. The vehicle could not even be started if it were not for the friction exerted between the tires and the road. Nails hold in wood, and screws hold in either wood or metal by reason of friction, without which they would be useless. Walking is difficult enough on an icy pavement, but it would be wholly impossible if there were no friction at all between the shoe and the pavement.(5分)3.1Friction arises when____.(1分)A. an opposing force of motion existsB. the energy is wastedC. everything is motionlessD. a complicated machine is supplied with energy
3. In the early 1600's, a group known as the Separatists lived in England. They were people who wanted to worship God, study the Bible and pray, but the English laws did not allow them to worship as they desired. They were hunted down, beaten, and locked up.Eventually, they heard about freedom of religion in Holland, and planned to escape. After much hardship, they were allowed to leave England.Now called Pilgrims, they lived in Holland for 12 years, but left because they couldn't stand the hard life, and couldn't work their own trades. They wanted to find a Kingdom of God for their posterity (后代) to practice religion freely. So they hired the Speedwell and the Mayflower to carry them across the Atlantic to a new land in America.The Speedwell had many leaks and had to turn back. The Mayflower took in their passengers, making a total of over 100. They sailed two months and three days, cramped and hungry.On November 11, 1620, the Mayflower spotted land. They landed in Province town, Massachusetts. For over a month, they sent men to find the perfect place for them to build their colony. When they finally found a place, they called it Plymouth.Right away they started building homes, knowing winter was near.Unfortunately, a violent storm hit when the houses were not yet finished. The Pilgrims were forced to stay on the cramped (狭窄的) Mayflower for their first winter in the new world. When this winter was over, over half of them had died.The Pilgrims eventually made a good friend who helped them. His name was Squanto. He showed them where fish swam, how to hunt deer, and how to plant corn.Squanto was a Native American who was kidnapped (绑架) earlier in his life and taken to England. This is why he was able to communicate with the Pilgrims.With the help of the Native Americans, there was plenty for everyone to eat that first summer, and also plenty to last for the next winter.The Pilgrims had so much to be thankful for. They gave thanks for good friends, new homes, freedom of religion, and plenty of food in a three-day celebration with their Native American friends.Today we continue the celebration of the Pilgrims and the Native Americans, and call it Thanksgiving.(5分)3.1 The Separatists left England in pursuit of____.(1分)A. wealthB. adventureC. an easier lifeD. religious freedom
22. Chess must be one of the oldest games in the world. An Arab traveler in India in the year 900 wrote that it was played "long, long ago". Chess was probably invented in India, and it has been played everywhere from Japan to Europe since 1400. The name "chess" is interesting. When one player is attacking the other's king, he says, in English,"check". When the king has been caught and cannot move anywhere, he says "check mate". These words come from Persian. "Shah mat" means "the king is dead". That is when the game is over, and one player has won.Such an old game changes very slowly. The rules have not always been the same as they are now. For example, at one time the queen could only move one square at a time. Now she is the strongest piece on the board. It would be interesting to know why this has happened! Chess takes time and thought, but it is game for all kinds of people. You don't have to be a champion in order to enjoy it. It is not always played by two people sitting at the same table. The first time the Americans beat the Russians was in a match played by radio. Some of the chess masters are able to play many people at the same time. The record was when one man played 400 games! It is said that some people play chess by post. This must make chess the slowest game in the world.(10分)22.1 Which of the following is known to be true?____(2分)A. Chess is an old Indian traveling game.B. Chess is the oldest game in the world.C. Chess was played in Japan and Europe before 1400.D. Chess was played in India long before 900.
