Before this global sporting event, we started thinking about sports that didnt exist any more and sports that were maybe a little strange. Read the following ones that have ever been included in the past Olympic Games.Live Pigeon Shooting(1900)This bloody event was only held once, at the 1900 Paris Games. Nearly 300 birds were killed during the competition, leaving a crime scene of feathers and blood. This is the only event in Olympic history that involved killing live animals.Kabaddi(1936)This sport if popular in South Asia. The object is for one member of a team to enter the other sides half of the field, and score points. The attacker then returns to his half of the field.12 Hour Bicycle Race(1896)Seven riders got on their bikes at 5 am and rode until 5 pm. Four riders dropped out before noon, but the winner, Adolf Schmal of Austria, managed about 180 miles. Only Schmal and one other finished.Tug of War(1900-1920)This may seem like a basic PE class sport more than an Olympic event, but Tug of War was actually one of the first sports played at the Olympic games in 500 BC. There are two teams of eight; the winning team must pull the other team six feet forward.Swimming Obstacle Race(1900)The athletes had to climb over a pole(杆子) and a row of boats, and then swim under another row of boats. All of this was done in the Seine River, so they also had to fight against the water. This event was only ever held in 1900, in Paris.11 . Which sport looks like a common activity more than an Olympic event?ASwimming Obstacle Race.B12 Hour Bicycle Race.CLive Pigeon Shooting.DTug of War.12 . How many athletes finished the event 12 Hour Bicycle Race?AOneBTwoCFourDSeven13 . What does the underlined phrase “drop out” mean in English according to the passage?AGive upBRun outCFall off.DBreak down14 . What can we learn from the passage?AAthletes took part in all of the events in teams.BTug of War was held in the Olympics only once.CSome of the events may be in the 31st Summer Olympics.DThese events are not as popular as they used to be.Young sunflowers turn and swing every day. New findings add to evidence that the plants are animal-like.Harmer, a professor in the University of California at Davis, Department of Plant Biology, carried out a series of experiments on sunflowers in the field, in pots outdoors and in indoor growth chambers.By staking plants so that they could not move, Harmer showed that he could destroy their ability to track the sun. He also noticed that sunflowers prevented from moving were not as tough and leafy as those that were free to move. When plants were moved indoor with a settled overhead light, they continued to swing back and forth for a few days.The indoor plants did start tracking the “sun” again when the apparent source of lighting was moved across the room. The plants could reliably tack the movement and return at night when the artificial day was close to a 24-hour cycle, but not when it was closer to 30 hours.When sunflowers track the sun, the east sides of their stems grew more rapidly than the west sides. At night, the west sides grew faster as the stem swung the other way. The team identified a number of genes that were expressed at higher levels on the sunward side of the plant during the day or on the other side at night. A plant growth-regulating hormone (激素), called auxin, appears to be a key driver.The “dance” to the sun cycle obviously slows when the sunflower matures (成熟) and its flowers open up. At that point, the plants stop moving during the day and settle down facing the sun in the east.“Bees like warm flowers.” Harmer said, adding that the bees are cold-blooded, so landing on a warm flower saves them energy and perhaps feels really good.“The morning warmth changes the flowers in a way to make them more appealing to insects, perhaps causing them to release more attractive scents earlier in the day.” he said “Were currently testing this idea.”15 . Why did Harmer do the experiment on sunflowers?ATo see how sunflowers grow upBTo show what sunflowers genes are.CTo study why sunflowers track the sun.DTo check if sunflowers swing in cloudy days.16 . What does the underlined word “staking” probably mean in Paragraph 3?AbreakingBcontrollingCgrowingDsearching17 . What is the result of sunflowers being stopped from moving?AThey will produce a number of new genes.BThey will grow faster than usual.CThey wont swing back though set free.DThey wont grow well.三、阅读判断阅读短文，并根据短文内容判断短文后面句子的正误。正确为T错误为F。Fire can help people in many ways.
