ene is a sheet of carbon, but only one atom thick. You don39。 t have to look far to find graphene— it39。 s all around you. If you want this hightech wonderstuff, all you need is a pencil, paper and a little adhesive tape. Use the pencil to shade a small area on the paper, and then apply a small piece of adhesive tape over the area. When you pull up the tape, you39。 11 see that it pulls up a thin layer of some of the shading from your pencil. That layer is called graphite, one of the softest minerals in the world. Now stick the same piece of tape on another sheet of paper and pull the tape upthere should be an even thinner layer, this time left on the paper. Now imagine that you do this over and over, until you get the thinnest possible layer of material on the paper. This layer would be only one atom thick, and you wouldn39。 t be able to see it. Graphite is made of layers of graphene. So when you get to the thinnest possible layer, you39。 ve found graphene. 31. What would change the future of electronics according to engineers?( C ) A. Personal puter. B. Big technology. C. Graphene. D. Creative ways. 32. Which of the following statements about graphene is true ?( B ) A. It is visible to the human eye. B. It is possibly the thinnest material in the world. C. It can be used to make paper. D. Finding it demands time and money. 33. The word “apply” in paragraph 4 could be used to replaced by ? ( D ) A. push. B. find. C. collect. D. put. 34. What does the writer tell in the last two paragraph ?( A ) A. An easy way to find graphene. B. Significance of the discovery of graphene. C. Development of hightech wonders. D. Possible applications of graphene. 35. Graphene39。 s super strength lies in the fact that.( C ) A. It is the thinnest material in the world. B. It is made of the most abundant elements in the world. C. It can help to make electronic ponents smaller. D. It helps engineers to produce more sensitive electronic products. 第二篇 Puerto Rican Cuisine(菜肴 ) Puerto Rico, a Caribbean (加勒比海区 ) island rich in history and remarkable natural beauty, has a cuisine all its own. Immigration(移民 ) to the island has helped to shape its cuisine, with people from all over the world making various contributions to it. However, before the arrival of these immigrants, the Taino people lived on the island of Puerto Rico. Taino cuisine included such foods as rodents (啮齿动物 ), fresh shellfish and fish fried in corn oil. Many aspects of Taino cuisine continue today in Puerto Rican cooking, but it has been heavily influenced by the Spanish, who invaded Puerto Rico in 1508, and Africans, who were initially brought to Puerto Rico to work as slaves. Taino cooking styles were mixed with ideas brought by the Spanish and Africans to create new dishes. The Spanish extended food choices by bringing cattle, pigs, goats, and sheep to the island. Africans also added to the island39。 s food culture by introducing powerful, contrasting tastes in dishes. In fact, much of the food Puerto Rico is now famous for coffee, coconuts, and oranges was actually imported by foreigners to the island.
