单选题For many people today, reading is no longer relaxation. To keep up their work they must read letters, reports, trade publications, interoffice communications, not to mention newspapers and magazines: a never-ending flood of words. In (56) a job or advancing in one, the ability to read and comprehend (57) can mean the difference between success and failure. Yet the unfortunate fact is that most of us are (58) readers. Most of us develop poor reading (59) at an early age, and never get over them. The main deficiency (60) in the actual stuff of language itself--words. Taken individually, words have (61) meaning until they are strung together into phrased, sentences and paragraphs. (62) , however, the untrained reader does not read groups of words. He laboriously reads one word at a time, often regressing to (63) words or passages. Regression, the tendency to look back over (64) you have just read, is a common bad habit in reading. Another habit which (65) down the speed of reading is vocalization-- sounding each word either orally or mentally as (66) reads. To overcome these bad habits, some reading clinics use a device called an (67) , which moves a bar (or curtain) down the page at a predetermined speed. The bar is set at a slightly faster rate (68) the reader finds comfortable, in Order to "stretch" him. The accelerator forces the reader to read fast, (69) word-by-word reading, regression and subvocalization, practically impossible. At first (70) is sacrificed for speed. But when you learn to read ideas and concepts, you will not only read faster, (71) your comprehension will improve. Many people have found (72) reading skill drastically improved after some training.

He is delighted that how he can (75) a lot more reading material in a short period of time.

单选题Jonnie (was not) barely able to walk (without help)(because of) the (bad) injury in his left leg.

单选题My father was a foreman of a sugar-cane plantation in Rio Piedras, Puerto Rico. My first job was to drive the oxen that plowed the cane fields. I would walk behind an ox, guiding him with a broomstick. For $1 a day, I worked eight hours straight, with no food breaks. It was very tedious work, but it prepared me for life and taught me many lasting lessons. Because the plantation owners were always watching us, I had to be on time every day and work as hard as I could. I"ve never been late for any job since. I also learned about being respectful and faithful to the people you work for. More important, I earned my pay. I was only six years old, but I was doing a man"s job. Our family needed every dollar we could make because my father never earned more than $18 a week. Our home was a three-room wood shack with a dirty floor and no toilet. Nothing made me prouder than bringing home money to help my mother, father, two brothers and three sisters. This gave me self-esteem, one of the most important things a person can have. When I was seven, I got work at a golf course near our house. My job was to stand down the fairway and spot the balls as they landed, so the golfers could find them. Losing a ball meant you were fired, so I never missed one. Some nights I would lie in bed and dreamt of making thousands of dollars by playing golf and being able to buy a bicycle. The more I dreamed, the more I thought. Why not? I made my first golf club out of guava limb and a piece of pipe. Then I hammered an empty tin can into the shape of a ball. And finally I dug two small holes in the ground and hit the ball back and forth. I practiced with the same devotion and intensity I learned working in the field—except now I was driving golf balls with club, not oxen with a broomstick.

单选题If you smoke-particularly cigarettes-you are far more likely than a non-smoker to suffer or die from several major diseases-notably lung cancer.One smoker in four dies prematurely (过早的) because of his smoking. The risk of dy-ing for a heavy smoker (between the ages of 35 and 55) is roughly equal to the risk run by a non-smoker 10 years older.Cigarette smoking-and to a lesser degree pipe and cigar smoking--may aggravate (使恶化) or be partly responsible for the development of a wide variety of other diseases, which include cancers of the mouth and throat, peptic ulcers (胃溃疡), and loss of teeth.(78) Women who smoke during pregnancy produce babies on average about 5 to 8 ounces lighter than those who don't. Take lung cancer for example.Britain's lung cancer figures are the highest in the world, and still rising. Ninety peo-ple die every day, 33,000 in 1969. Almost all these deaths can be attributed directly to to-bacco smoking. (79) The prospects of a cure for lung cancer are, at present, remote, and it is impossible to estimate when, if ever, someone will find one. You would be foolish to rely on someone finding a cure before you needed it.One man in eight who die between the ages of 35 and 64 is killed by lung cancer. The figures for women in this age group are lower, about 1 in 20. This is partly because women smoke less, and have not smoked as long. But the figures are still very high.

单选题The following is an African folktale: Long ago the sky was close to the Earth, people did not have to plant their own food. Instead, when they were hungry, they just reached up and broke off a piece of the sky to eat. Sometimes the sky tasted like ripe bananas. Other times it tasted like roasted potatoes. The sky was always delicious. People spent their time making beautiful cloth. They painted beautiful pictures and sang songs at night. The grand king, Oba, had a wonderful palace. His servants made beautiful shapes out of pieces of sky. Many people in the kingdom did not use the gift of the sky wisely. When they took more than they could eat, the sky became angry. Some people threw the extra pieces into the garbage. Early one morning the angry sky turned dark. Black clouds hung over the land, and a great sky voice said to all the people, "You are wasting my gift of food. Do not take more than you can eat. I don"t want to see pieces of me in the garbage anymore or I will take my gift away." The king and the people trembled with fear. King Oba said, "Let"s be careful about how much food we take." For a long time, all the people were careful. But one man named Adami wasn"t careful. At festival time, he took so many delicious pieces of sky that he couldn"t eat them all. He knew he must not throw them away. So he decided to try to hide the pieces at the bottom of the garbage pile. Suddenly, the sky became angry and the clouds turned black. "You have wasted my gift of food again," yelled the sky. "This time I will go away so you cannot waste me any more." "You will have to learn how to plant crops in the ground and hunt in the forests. If you work hard, you may learn not to waste the gifts of nature." Everyone watched as the sky sailed away. From that time on, they worked hard to grow their food and cook their meals. They always tried to remember not to waste the gifts of nature.
