the strangest sport anyone has ever invented. and at first sight, it looks like the easiest. competitors have to do two things. the first is to stand still. the second is to place their hands anywhere on the body of a car, and keep it there.this is where things start getting difficult. lots of people are doing the same thing. and the winner of the “handstand” contest is the person who can carry on doing it for the longest time. that person gets to own the car.it still seems to be an easy thing to do. at the beginning it is. anyone can stand still. but when the contest has been going for four or five days, standing still seems like the most difficult job in the world . and keeping the hand in place over this time becomes an act of serious attention. after a few days, the hand seems to belong to someone else-someone who wants to go home and get some sleep.competitors are allowed to take a five-minute break every hour to eat, drink or do whatever else is necessary. no one is allowed to lean on the car for support. winners need to be able to show great powers of attention. they also need to be able to develop special skills.www.maybe the popularity of the “handathon” is due to the fact that it is not necessary to be a trained athlete to enter. competitors in the longview handathon certainly dont seem to do much preparation. most say they will prepare by “getting lots of sleep”. others say they will “eat healthy food” or “pray for success”. the whole event gives ordinary people the chance to do something interesting and win something in the end.handathons are competitions, but there is little rivalry (竞争) between competitors. they help each other out and keep each others spitits up. people who drop out early return with food, drink and encouragement.29 what ability is most important in a handathon?anot leaning on the carbstanding without any supportchaving strong powers of attentiondeating and drinking in five minutes 30why is handathon popular?aanyone who is interested can join in it.bsomeone can win with special trainingcit doesnt need to make any preparationdpeople get along well with each other in it. 31which of the following statements about the “handathon” is right?acompetitors are not allowed to drop outbcompetitors dont encourage each otherccompetitors can sit down and take a 10-minute break every hourda competitor has to place his or her hand anywhere on the body of a car. 32which is the writers opinion about the “handathon”? ait is the easiest of all sports.bit can last a whole day.cit is not as easy as it looks at first.dit is no good competing in a “handathon”das the population of the planet increases, so does the number of homes, business, parking lots, schools, airports and roadways. all these structures use electricity and need to be lighted. humans demand light. they want their homes more comfortable and they want their streets safe. the problem is that researchers are finding that all the light is having a negative effect on humans and wildlife as well. less than 10 years ago i drove to a thinly populated section of my own, lay down in the middle of the road and watched an attractive meteor shower(流星雨). if i did that today, i wouldnt be able to see the meteor shower.nowadays scientists are finding light pollution can be almost as bad as carbon dioxide （二氧化碳）pollution. one of the saddest parts of light pollution is that most of it is unnecessary and most of the outdoor light that we use is wasted. one only needs to look at a row of street lights to see how much of the lights shines upwards and lights the sky: a total waste of electricity.additionally, the production of electricity creates pollution by releasing greenhouse gases. this affects the air we breathe and our quality of life.scientists are also studying the effects of light pollution on wildlife. thousands of birds die each year when they crash into highly lighted buildings, as they become puzzled by the light. it has been long known that tiny baby sea turtles become lost and follow the light on the shore instead of heading towards the sea.fortunately, light pollution is one of the easiest sources of pollution that can be corrected without a negative effect. following some guidelines and a little searching on google can give you many ideas on how to reduce your contribution to light pollution.33according to the passage, the best way to deal with light pollution is to _.areducing the output of lightsbeducating people about light pollutioncavoiding the use of unnecessary lightingdinventing environmentally-friendly lights34what can be inferred from the passage?aastronauts cant see clearly in space nowadaysbglobal warming results in light pollution in some waycwe are almost at a loss how
