Ever since farmers began to grow grain, they have had to protect their crops from birds. In the 1300's, English farmers hired children to protect their crops. They were called "bird scares". The children chased birds and threw stones at them. Bird scares were replaced in the 1800's by scarecrows. A scarecrow is anything that is set in a field to scare birds away. Often it is a pole dressed like a person. Some farms with small fields still use scarecrows today. Farming became big business in the twentieth century. Scarecrows could no longer protect the huge fields of grain, so farmers used poisonous chemicals on the fields. The poison made the grain bitter. The birds usually would not eat the bitter grain. Although they can prevent crops from being destroyed by insects and birds, some chemicals can be harmful to humans. Therefore, farmers are using fewer chemicals now than they did twenty years ago. Perhaps scarecrows may be seen more often in the fields in the future. "Bird scares" keep birds away from crops by _ . A) feeding them bitter grain B) pretending to be scarecrows C) spreading chemicals in the fields D) chasing them and throwing stones

Wearing seat belt is,of course,the first step to safe driving.These additional measures might also save your life. Count to three.Keeping up enough space between your car and others is extreme1y necessary.Jim Clark,a California driving instructor,suggests a least amount of three seconds'following distance.To figure this,pick an object on the roadside ahead.When the car in front of you passes it,start counting one-thousand-one,one-thousand-two,one-thousand-three.If you get to that object before you reach one-thousand-three,you don't have three seconds of following time --- time needed to keep away from accidents. Let followers pass."If someone's driving after you,get out of his way,"Clark advises."You're better of being safe than right." Expect the worst.In a study,the Federal Highway Administration found that 68 percent of drivers do not come to a complete stop at stop signs.When you're driving and see someone come near to a stop sing,assume the person's not going to stop. And when you stop at a crossing and another car comes near with its turn signal on,don't take it true that the driver will turn.Instead,wait until he turns.He may have had the signal on for miles. Stay outside.In crowd,multilane traffic,drive in either the outside--left or outside--right lane."That allows you somewhere to go if a problem develops,"traffic expert Francis Kenel says."If you're in the middle,all you can do is to pause from time to time." According to the text if you want to drive safely you should . A) wear seat belt B) take some additional measures C) at least take 5 steps D) count to three

Q: These days, young children can enjoy directly what it is like to be a marine biologist at a marine association. What they discover can lead them to appreciate and protect the ocean and also the animals living in it. At the present time, learning isn't only limited to the classroom. It's quite common for kids to learn from outdoor experiences. Teachers commonly take their pupils on field trips to museums as well as other interesting areas. If you wish to help pupils to take care of the ocean, one of the best areas to take them to is a marine association, the place where the ocean biome is shown. Taking your pupils to a marine association is a prefect way to help them learn. Education professionals agree that there are topics that children can learn more successfully whenever they experience them directly.

They not only get to research creatures from the ocean, but they also get to see, touch, and smell most of these animals and plants. This type of _ offers students an idea about the life of a marine scientist. It could help them choose a career afterwards. These programs are generally held on Saturdays and Sundays in order that kids and parents can have more hours in which to have fun. Teachers who want to arrange these activities for their students can call a local marine association near them. The text is most probably taken from _ .

HANGZHOU, China -- Millions of Chinese basketball fans who were upset about the retirement of Yao Ming, are excited to see another even more shining star, Jeremy Lin, rising from the N.B.A and becoming a household name all across China. "We are amazed by Lin Shuhao's magic performance and should cheer him on," one Internet user wrote. "His sport shirts have sold out, even including the counterfeit ones," said Zheng Xiaojun, a 24-year-old clerk. Lin's amazing success over the last month has caught the imagination of the Chinese. He has been particularly popular here in northern Zhejiang province, from which his grandmother went to Taiwan in the late 1940s. Cai Qi, a well-known micro blogger, posted a message on micro blog over the weekend stating that Lin's hometown is Jiaxing, a city near Hangzhou where Lin's grandmother grew up. Cai Qi's nephew Yu Guohua, a 56-year-old factory worker, is Lin's closest still living in northern Zhejiang. He said in a telephone interview that Lin had come to play basketball with the Jiaxing High School team last May and had been surrounded by admirers. Yu said he did not have a chance to meet Lin in the crowd, but managed to speak with his family. "His father was very supportive of Lin's playing basketball, but his grandmother was not, for fear he would be injured," Yu said. Lin may owe his height, 6 feet 3 inches, to his grandmother's family, Yu said. Chen Weiji, the father of Lin's grandmother, was well over 6 feet and all of Chen's children were tall as well, he said. The N.B.A. believes that 300 million people in China play basketball. The retirement last year of Yao Ming took its main Asian draw away from the N.B.A. But Lin's appearance has helped the league remain a hot topic of Chinese online chatter. Why does Lin Shuhao appeal especially to people in northern Zhejiang ? A) He was born in Zhejiang. B) His sports shirts are made in Zhejiang. C) He once visited Zhejiang. D) His grandmother grew up in Zhejiang.
