2019年自考英语二历年试题(真题)及答案

2019年10月髙等教育自学考试全国统一命题考试 英语(二)试卷(课程代码:00015) 本试卷共8页,满分100分,考试时间150分钟。 考生答卷前必须将自己的姓名和准考证号写在答题卡上。 必须在答题卡上答题,写在试卷上的答案无效。 第一部分:阅读判断(第1?10题,每题1分,共10分) 下面的短文后列出了10个句子,请根据短文的内容对每个句子作出判断:如果该句提供的是正确信息,选择A;如果该句提供的是错误信息,选择B;如果该句的信息文中没有提及,选择C。在答题卡相应位置上将答案选项涂黑。 To Lease(租赁) or Not to Lease Planning to lease a car because you don't think you can afford to buy? Think again. Leasing can end up being just as expensive as buying. Most people think about leasing because they believe it will cost them less money. They're right-it is cheaper, but only in the short term. For example, if you were to lease anew Subaru Forester, you might pay $300 per month for the car. If you were to buy the same car, you would pay about $400 per month. Over a three-year, you would save $3600-a big savings. But after your lease is over, you have to give the car back. Many people want to lease because they can drive a more expensive car than they might otherwise be able to afford. For example, if you spend $300 monthly on a car, you might be able to lease a new Ford Explorer. For the same price, you might have to buy a used Explorer, or buy a new but much less expensive model. A lease,therefore,allows you to drive the latest models of more expensive cars. However, whatever car you can afford to buy you get to keep it, and it will always have a resell or trade-in(以新旧换)value if you want to upgrade to a new car later. Furthermore, people who lease cars are often shocked by how much they must pay when the lease is over . Most leases limit you to a certain number of miles. If you go over that, you must pay for each mile. As a result, you may end up paying thousands of dollars in mileage(里程) fees. In addition, when you lease ,you have to pay for regular maintenance and repairs to the vehicle. Since you must return the car finally, you are paying to repair someone else's car.

Music can also reduce stress, make depression more bearable and help you relax. All the benefits of music can only be got if the listener enjoys the music he is listening to. If the listener dislikes the music or finds it boring,it will have a negative effect on him instead of a positive one. Now let's examine what most of us do when it

comes to listening to music. We usually just listen to a play list and allow a program to randomly(任意的)select the songs we are going to listen to. This is where the program lies. What if you liked the first song but found the second one boring? What if the third one was a motivating song while the fourth didn’t suit your emotions? What do you think the result will be? What you'll have is an emotional mess! The first song will lift your mood a little. The second will make you a little bored. The third will motivate you and then the fourth will put you down. In the end you’ll end up feeling worse than before. I strongly recommend dividing your play list into different small lists. For example, a list for relaxation, a list for motivation and so on. Another very important thing you must do is to get rid of all of the old music that you are bored of. Besides, don't listen to songs with negative words or messages. The music you listen to can delay your recovery from breakups(分手)by months and months!

The first hundred years after Christopher Columbus’s journey of discovery in 1492 did not produce any settlement on the North America continent but rather some Spanish trading posts further south, a great interest in gold and adventure and some colorful crimes in which the English had their part. John Cabot, originally from Genoa but a citizen of Venice was established as a trader in Bristol, England, when he made a journey in 1497. But his ship, the Matthew, with its crew of eighteen, did no more than see an island(probably off the New England coast) and return home. He and his son made further voyages across the north Atlantic which enabled the English crown to claim a "legal" title to North America. But for a long time afterwards the Europeans’interest in America was mainly corffined to the Spanish activities further south.
