Kids can build almost anything from them—a plane, a castle, even a race car. And if one part of a creation c

2、omes apart or breaks, the builder doesn’t have to start from scratch. He can just replace the missing blocks. And what’s true for kids’ play is also true for adult projects. Scientists have just created a new type that resembles the letter X. These pieces are small and lightweight yet strong. And

3、they’re inexpensive. One day they may be fixed into bikes, bridges, planes or buildings. Just as with toy blocks, if one piece breaks, engineers can swap it out without scrapping the whole project. “When you read about this invention, ”Rainer Adelung said, “you think: ‘Why hasn’t anyone done this

4、before?’” The material used in the new X blocks is often called, simply, a composite. Engineers took carbon fibers, each thinner than a human hair, and wove them into a hard plastic substance. Recently, the company Sprint Aero Systems approached Materials scientists Cheung and Gershenfeld for hel

5、p. It wanted some basic, big composite piece for an airplane. Cheung doubted whether this was a good idea. If one part of the big piece broke, the problem might spread, leading to a more disastrous breakup of the material. Instead, his team at MIT decided to create smaller composite pieces. They i

6、magined an airplane built from millions of identical blocks—the new X blocks. In the lab, he connected the blocks to make triangular pyramids. Then, he connected the pyramids to create a cube about 20 centimeters across. The cube weighed only as much as an egg, but supported more than about 295 kilo

7、grams before crushing. Because the new X blocks are so light, however, he does find them exciting. One reason: “Weight is a huge, huge concern”for cars and planes, he explains. It determines how much fuel they will use. 【文章大意】本文主要介紹了科學(xué)家們發(fā)明的一種新的類似積木的東西, 這種東西強(qiáng)度很高, 并且非常廉價(jià), 體積很小, 但是可以很方便地造成其他東西。 1.

8、 The first paragraph describes the blocks’ character of   . A. amusement B. effectiveness C. popularity D. convenience 【解析】選D。細(xì)節(jié)理解題。結(jié)合第一段的Any child. . . also true for adult projects. 可知, 孩子們玩的積木可以更換, 可以建造任何形狀的東西等, 說明了積木的方便性。 2. How did Rainer find the idea of X blocks? A. Fascinating.

9、 B. Confusing. C. Challenging. D. Discouraging. 【解析】選A。細(xì)節(jié)理解題。根據(jù)第三段的“When you read about this invention, ”Rainer Adelung said, “you think: ‘Why hasn’t anyone done this before?’”可知, 他認(rèn)為為什么這種發(fā)明不早點(diǎn)呢, 是對(duì)這種發(fā)明的一種贊美, 故選A。 3. Why did Cheung make smaller composite pieces? A. To make composite pieces

To produce the blocks in the same shape. 【解析】選B。細(xì)節(jié)理解題。結(jié)合第五段的最后一句話If one part of the big piece broke, the problem might spread, leading to a more disastrous breakup of the material. 和第六段的Instead. . . the new

11、X blocks. 可知, 他把這些東西做成很小的東西, 是防止它們散架, 故選B。 4. According to the passage, using the new X blocks   . A. people won’t worry about the fuel problem B. people won’t care about the weight of vehicles C. people can save more money by using less fuel D. people don’t need denser construction materials

12、 【解析】選C。細(xì)節(jié)理解題。從最后一段的“Weight is a huge, huge concern”for cars and planes, he explains. It determines how much fuel they will use. 可知, 重的東西耗油多, 因?yàn)檫@個(gè)東西比較輕, 可以節(jié)省油料的使用, 故選C。 B   Recreational tree climbing is taking root in the eco-tourism industry, and it’s sending guys like Tim Kovar to far off reache

13、s of the globe. Kovar, a tree-climbing instructor, recently returned to the U. S. from Brazil, where he spent time developing a tree-climbing operation thanks to the“slow travel”movement. Slow travel, is like the slow food movement, the practice of giving fast food in favor of homegrown cooking—th

14、e kind that takes hours to prepare and enjoy. Likewise, slow travel urges visitors to experience a place’s natural surroundings and learn about the ecology in a way not afforded by extreme games. “Tree climbing is a slow activity, ”says Kovar. “It’s not something you do quickly and then you’re on

15、to the next thing or event. ”There is no such thing as a quick climb, especially for beginners. This wasn’t a race against the clock or the fellow climbers. In fact, tree climbing is unlikely to ever become a feature of the extreme games. Many climbers refuse competition. There has already been so m

16、uch competition in the world. “When you stand below the tree, it can be amazing, ”Rusel DeMaria says, looking affectionately up at Michael’s Triumph, a 150-foot-tall tree. But reaching the treetop, he adds, is an entirely different feeling. Likewise, his wife, Viola Brumbaugh, kneels on the ground

17、 and asks Michael’s Triumph for permission to climb. “It goes a lot smoother that way, ”she says. And climbing has been included into many educational programs. New Tribe offers guided climbs through its school, Tree Climbing Northwest, where“we teach enough tree biology and forest ecology to rais

18、e awareness in our students, ”says New Tribe president Sophis Sparks. “We know that the tree climbing experience deepens personal appreciation for trees. After climbing, people value trees more and are motivated to support preservation. This is not just to preserve their playground. ” Perhaps that

19、is why he struggles with the term“recreational tree climbing, ”saying, “I prefer to call it inspirational tree climbing. ” 【文章大意】爬樹已經(jīng)成為生態(tài)旅游的一種形式, 它不但給人們帶來了樂趣, 而且還提高了人們保護(hù)樹木的意識(shí)。 5.

25、comes from the federal(聯(lián)邦制的)government.  1 States have been required to show progress through yearly testing. But states say testing tells only part of the story about efforts by schools and students to improve. So the Obama administration has eased the limits on states in measuring performance.

26、  2 This new measurement tool is called the Colorado Growth Model. The idea is to show academic growth, not just achievement on tests. It combines test scores, family income levels, school size, the ethnicity of the student and many other factors.  3 The graph shows a school’s average score on sta

27、ndardized tests as well as its academic growth. On average, students enter sixth grade at West Denver Prep performing below grade level.  4? The new assessment method shows that, each year, the average West Denver Prep student learns more math than ninety-four percent of all the students in Color

28、ado.  5? Josh Smith says perhaps the most important thing they should learn is to believe in themselves. A. The results from schools across the state are shown online on a graph. B. Reading and writing scores also show growth. C. For ten years now, federal law has tied this spending to studen

29、t performance. D. Therefore, the government feels it a great pressure. E. But three years later, most are outperforming other students across the state. F. However, the limits don’t work at all. G. The western state of Colorado, for example, has a new assessment method. 答案: 1~5. CGAEB 關(guān)閉Word文檔返回原板塊 - 7 -
