You find a telephone number in the phone book, dial it and then forget it. This is your short-term memory. It lasts less than 30 seconds. However you don’t look in the phone book for your best friend’s number. You know it. This is a long-term memory. Your long-term memory has everything you remember.Why do you forget something? What is the reason? You did not learn it in the beginning. This is the major reason for forgetting. But you can remember better. Here are some ideas.1. Move information from your short-term memory to your long-term memory. Practice the information. Spend time on it.2. Be sure that you understand the information.3. Do only one thing at a time. Study in a quiet place. You can’t listen to music and memorize at the same time.4. Try to connect the new information with something you already know.5. Divide the information into parts. Do not have more than seven parts. Learn one part and stop for a few minutes. Don’t try to learn all parts at the same time.6. Make a picture in your mind. For example, when you learn theword SOFA, make a picture in your mind of this furniture. Remember what it looks like.7. Try to relax when you study.

The rivers which had brought down the soil were steep near the mountains, but near the coast they were wide and rolling, deep enough for the small boats of the time to sail formiles. It was far enough south for the summers to be hot, so that the growing season lasted from six month in Maryland to about nice in South Carolina. If you add these ideal farming conditions to the early discovery of a New World crop which was always in demand in the Old world, you will readily understand why the Southern Colonies became a farming group.Tobacco! This was the breath of life in Virginia, the oldest of the Southern Colonies. Men talked, thought, and bought in tobacco. It was a farming country, and other crop were also grown, but while theSoutherner might have competition in the production of fruits and grains(wheat and rice and barley大麦)，in tobacco he was a master. Tobacco! It was a magic word. Everything revolved around its production and it had a tremendous effect upon life in the South.59.“A New world crop” i n the last sentence of the 1st paragraph most probably refers to_____A)wheat B)rice C)tobacco D)barley60.

A few minutes before six o’clock, they decided to leave. They walked to their car, and got in. They expected a quiet, peaceful ride home. Mr. Lestar was about to start the car when a gun-man jumped up from the back seat. “Drive me to Paris!” he demanded.“All right,”Mr. Lestar replied. “I’ll drive you anywhere you want to go. But first let my wife out of the car.”After Jean was safely out of the car, Mr. Lestar started the motor slowly, but his mind was racing. Unarmed and 81 years old, he knew he needed help. Where were the police? “Just my luck,”he thought. “If I were speeding, there would be a police car on every corner.” Then the car sped forward and Mr. Lestar began driving like a madman, running red lights, and driving the wrong way on one-way streets but not one police officer saw him.Obviously, Mr. Lestar’s plan was not working. He got a new plan ashe remembered that Lille Police Station was nearby. “All right,” he thought. “If I can’t bring the police to my car, I’ll bring my car to the police.” Then he drove his car crashing through the doors and stopped in the courtyard of the policestation. Mr. Lestar yelled, “Help!” Officers from the police station came running and quickly held the man.64.When Mr. Lestar saw a man pointing a gun at him, his first responsewas that ________.

The coast is very varied, with perhaps the best parts in the south-west of England and in the west of Scotland. The coast of Devon and Cornwall, in the south-west, is much indented(向内陆凹进)，with many sheltered bays and fine rough points of land extending out into the sea. With so large a population on so small an island the best parts of the coast are inevitably rather crowded during the summer ,but much of Devon and Cornwall is still unspoiled, with many picturesque(风景如画的)fishing villages. The other parts of the coast are less dramatic, being partly flat and partly steep.In the parts nearest to great centers of population big seaside-resort(海滨胜地) towns have grown up . Four of these--Brighton, Bournemouth and Southend in the south, and Blackpool in the north-west--have become important towns themselves, with more than 150,000 permanent residents each, and there are other big seaside towns whose inhabitants include many retired people .Some of these places are remarkable for the great number of visitors they receive, some to stay for a week or a fortnight ,some to spend a few hours on the before returning home in the evening.69.
