It is the color of grass and the leaves on trees. It is also the color of most growing plants. Sometimes, the word “green” means young, fresh and growing. For example, a greenhorn is someone who has no experience. In the 15 th century, a greenhorn was a young cow or an ox whose horns(角)had not yet developed. A century later, a greenhorn was a soldier who had no experience in war. By the 18 th century, a greenhorn had the meaning it has today—a person who is new in a job. Someone who is good at growing plants is said to have a green thumb(大拇指). The expression comes from the early 20 th century. A person with a green thumb can make plants grow quickly and well. The Green Revolution(绿色革命)is the name given some years ago to the development of new kinds of rice and other grains. It was the result of hard work by agricultural scientists who had green thumbs. Green is also the color used to describe the powerful feeling. Jealousy(嫉妒). The green－eyed monster is not a dangerous animal from outer space. It is an expression used about 400 years ago by the British writer William Shakespeare in his play “Othello”. It describes the unpleasant feeling when someone has something he wants. In most places in the world, a green light is a signal(信号)to move ahead. In everyday speech, a green light means approval(赞成)to continue with a project. 26. A new solider was called a greenhorn in the __ __ century. A. 15 th B. 16 th C. 18 th D. 20 th 27. A person with a green thumb___ _. A. is good at growing plants B. really has a green thumb C. has no experience in war D. is new in a job 28. A man may meet the green eyed monster if __ __. A. he sees a dangerous animal B. he can’t get something C. he reads a sad play D. his friend gets a prize that he wants 29. This passage doesn’t mention the history of the expression “_ ___”. A. a green B. a greenhorn C. the green eyed monster D. a green light 30. Which would be the best title of the passage? A. Green, the color of grass and trees B. The stories about the color “green” C. Green, a sign of approval D. Different meanings of “green” 【2015年辽宁沈阳市】 B Mr Li: Sam, did you enjoy your first Spring Festival in China? Sam: Yes, I did. During this festival, many family members get together. Mr Li: Yes. I hear that at Thanksgiving Americans also get together for a special meal. It sounds similar. Sam: Yes. It’s similar. During these holidays, both the Chinese and Americans come home and have a big dinner. It’s great fun. Mr Li: What do you think are the main differences between the Spring Festival and Thanksgiving? Sam: Well, we take part in different activities and eat different kinds of food. In China, people usually set off fireworks and eat dumplings.
