1、阅读强化训练(十四)学生用书P154(单独成册)(建议用时：25分钟) 阅读理解It might be easy to imagine that the more crowded a bird flock(群) becomes, the slower the birds fly. But it has been proven that the bigger a bird flock becomes, the faster the birds will fly. The discovery was made by scientists from Swedens Lund University.
2、They took a look at the flying speed of birds in an effort to find what influenced how fast they would fly.Most of the findings didnt surprise the researchers. A birds weight and its wing shape, wind speed and direction, and the purpose of the flight all indeed influenced its flying speed. But the s
3、cientists found that the size of the flock had a strong effect on the flying speed, which had not been expected. The scientist Anders Hedenstrm expressed surprise at the discovery as it has usually been ignored in studies on birds.Anders Hedenstrm and his partner Susanne Akesson collected their data
4、 on Swedens land Island. There they studied birds physical characteristics(特征), counted flock populations, and recorded their speeds during flying. To know the birds speed while flying, they used a tool that can also gauge important characteristics of wind, including speed and direction. They were a
5、ble to measure the speed of different kinds of large flocks. The researchers results showed that bigger flocks fly faster no matter what kind of bird species they belong to. Why thats the case is the next question they hope to answer.The researchers also said that large flocks are made up of largers
6、ized birds, which move at faster speed than smaller birds. In a large flock, it is easier to take advantage of the turbulence(湍流) that occurs behind other birds, especially when flying in formation(队形), like geese and other birds do. Using the turbulence makes it easier to maintain higher speed.【解题导
7、语】原本人们认为鸟群的数目越大，就会飞的越慢，而最新的研究却得出了完全相反的结果。这是为什么呢？1What does Paragraph 1 mainly tell us?AThe bigger the bird flock is, the faster the birds fly.BThe bigger the bird flock is, the slower the birds fly.CWhat affects birds flying speed didnt interest people.DThere was no further progress in studying bird
8、s flying speed.A解析：段落大意题。根据第一段的内容可知，最新的研究表明：并非鸟群的数目越大，飞行速度越慢，而是恰好相反。2What does the underlined word “gauge” in Paragraph 3 probably mean?AMeasure.BAffect.CChange. DControl.A解析：词义猜测题。根据划线词后面的They were able to measure the speed of different kinds of large flocks.可知，gauge意为“测量”。3What can be learned from
9、 the last paragraph?ABirds are naturalborn flyers.BBigger birds fly slower than smaller ones.CTurbulence helps birds maintain higher speed.DThe goose is the slowest flying bird in the world.C解析：推理判断题。根据最后一段的内容可知，鸟类可以利用大气湍流维持飞行速度。 完形填空I am an eighthgrade student at Central Middle School.
