BSpending two or three hours playing outdoors each day can reduce a child’s chance of becoming short-sighted, a research shows. It challenges (挑战) the belief that short- sightedness is caused by computer use, watching TV or reading in weak light.The Australian government researchers believe that sunlight is good for people’s eyes. They compared the vision(视力) and habits of 100 seven-year-old children in Singapore and Australia. In all, 30% of the Singaporean children were short-sighted--this rate(比率) was ten times higher than Australian children.Both groups spent a similar amount of time reading, watching television and playing computer games. However, the Australian children spent an average(平均) of two hours a day outdoors—90 minutes more than the Singaporean children.Professor(教授) Ian Morgan, from the Australian Research Council’s Vision Centre, said, “Humans are naturally long-sighted, but when people begin to go to school and spend little or no time outdoors, the number of short-sighted people gets larger. We’re also seeing more and more short-sighted children in cities all around the world—and the main reason may be that city children spend less time outdoors. “Daylight can be hundreds of times brighter than indoor light. But why does playing outside prevent us from becoming short-sighted? Scientists believe that natural light has a special chemical(化学物质) which stops the eyeball from growing out of shape and prevents people becoming short-sighted.So be outdoors. It doesn’t matter if that time is spent having a picnic or playing sports.24. How much time did the Singaporean children spend outdoors on average every day in the research?A. 2 hours. B. 90 minutes. C. 1 hour. D. 30 minutes.

阅读理解Most of us can find 15 minutes or half an hour each day for some specific regular activity.It may be a free period or a regular wait, say in the queue for a bus or meal --- even while eating breakfast.One famous surgeon always made it a rule to spend at least 15 minutes on general reading before he went to sleep each night.Whether he went to bed at 10 pm or 2:30 am made no difference.Even if you cannot keep to this kind of discipline, it is a good idea to make sure you always have a general interest book in your pocket.Don’t forget it should be a book which entertains you and the English must not be too difficult for you.Nearly all “speed reading” courses have a “pacing” element --- some timing device which lets the student know how many words a minute he is reading.You can do this simply by looking at your watch every 5 or 10 minutes and noting down the page number you have reached.Check the average number of words per page for the particular book you are busy reading.Well, this is difficult at first.A friend can help by timing you over a set period, or you can read within hearing distance of a public clock which strikes the quarter hours.Pace yourself every three or four days, always with the same kind of easy, general interest book.You should soon notice your habitual w.p.m.rate creeping up.6.The passage recommends setting aside for reading practice().A.two hours a dayB.one hour a dayC.15 minutes or half an hour a dayD.three minutes a day before meal7.One famous surgeon always made it a rule to read() .A.15 minutes at 10 pm each nightB.for at least 15 minutes at bedtimeC.no matter it was early or lateD.whenever he had a spare moment8.It is a good idea always to carry in your packet ().A.a book you will never forgetB.a serious bookC.several books of various kindsD.an easy and interesting English book9.According to the passage, a “pacing” device() .A.measures a student’s reading speedB.is not included in most speed reading coursesC.is an aid to vocabulary learningD.should be used whenever we read alone10.Looking at your watch every 5 or 10 minutes ().A.avoids the need for reading fasterB.is not the same as pacingC.is not easy at firstD.helps you to remember the page number you were at last time

Passage FiveIn the United States, it is important to be on time, or punctual, for an appointment, a class, etc. However, this may not be true in all countries. An American professor discovered this difference while teaching a class in a Brazilian (巴西的) university. The two-hour class was scheduled' to begin at 10 A. M. and end at 12. On the first day, when the professor arrived on time, no one was in the classroom. Many students came after the scheduled time. Several arrived half an hour later. Few apologized for their lateness. Were these students being rude? He decided to study the students, behavior.The professor talked to American and Brazilian students about lateness in both an informal and a formal situation: at a lunch with a friend and in a university class. He found that if they had a lunch appointment with a friend, the average American student defined lateness as 19 minutes after the agreed time. However, the average Brazilian student felt the friend was late after 33 minutes.In an American university, classes not only begin at the scheduled time in the United States, but also end at the scheduled time. In the Brazilian class, only a few students left the class at 12: 00; many remained past 12: 30 to discuss the class and ask more questions. While arriving late may not be very important in Brazil, neither is staying late.51. The word "punctual' most probably means______.A. leaving soon after classB. coming earlyC. arriving a few minutes lateD. being on time
共用题干第三篇Sprained（扭伤）AnkleOne of the most common injuries teenagers and adults experience is a sprained ankle.A sprain occurs when the ligaments（韧带）of a joint are twisted（扭伤）and possibly torn. Ligaments are bands of fibers that hold the bones of a joint in position.A sprain can occur from a sudden twisting at the joint,or a stretching or tearing of the fibers of the ligaments. The injured area usually swells（肿胀）and becomes black and blue. Stepping off the sidewalk at the wrong angle or having one foot land in a hole while walking or running can leave you rolling on the ground in pain with an ankle on fire!If you cannot walk without experiencing intense pain,you must seek medical help.If the pain is manageable,and you can walk,here are three words to help you remember how to treat yourself:● Elevate（抬高）●Cool● Bandage（打绷带）As soon as there is injury to that ligament,there will be a certain amount of bleeding under the skin. Once the blood poois around the damaged blood vessels,swelling occurs.The pressure from the swelling results in additional stress and tenderness to the region.In order to reduce the degree of swelling,lie down as soon as possible and keep the ankle elevated so that it is actually higher than your heart. Next,to reduce blood distribution and keep bleeding（流血）to a minimum , apply a cold pack. After 20 minutes , take thepack off,wait half an hour,and then reapply.This can be done several times a day for a total of three days.Never leave a cold pack on for more than 20 minutes at a time.Reducing the temperature in that area for an extended period of time signals the body to increase blood flow to raise the body temperature!Therefore, one accidentally triggers（引起）more blood distribution to the affected area by leaving a cold pack on for too long!Finally,bandage the ankle.Be careful not to wind it too tightly;doing so can restrict blood flow and cause harm to the entire foot.Once the initial cold pack is removed,what is to be done?A:Begin bandaging the ankle.B:Wait 30 minutes and then reapply the ice pack for 20 minutes.C:Keep the ankle in a position lower than your heart.D:Wait 20 minutes and then reapply the ice pack for 30 minutes.
