I stood there listening to my father shout at top of his voice. The 16 on his face said that one of us had done something wrong.“ 17 one of you did this?”We all stared down at the step. There was child’s handwriting in chalk (粉笔) there. I was very 18 . I hoped no one could see it. Would he guess it was me? I was so scared. When he asked me, I 19 : “Not me, Dad.”The others denied (否认) it as well. Of course, we all knew that one of us 20 have done it. But as the 21 and smalle st of the three, I just couldn’t find the courage (勇气) to tell the and smallest of the three , I just couldn’t find the courage to tell the ____22___.To find out who had written on the 23 , Father gave us each a piece of paper and a pencil. “I wa nt each of you to 24 exactly what you see on the step.”I tried my best to write the words 25 . I didn’t want Dad to be able to tell it was me.He gathered up our pieces of paper and looked at them. “Since 26 of you will admit to have done it, then I will punish you all.” I stood there and said 27 . The last thing I wanted was for Dad to punish me!“I ___28___ it.” My sister stepped forward and said she had done something she hadn’t. She was grounded (受处罚) for a month.We didn’t talk about that for many years. Not __29____we were all older and I knew it was safe to finally tell my dad it was really____. I always felt sorry because of it. That was the last time I let anyone take the blame (责任) for me.16.A. sound B. taste C. look D. feeling17.A. What B. Which C. Who D.

The answer is no – especially when you’re talking about materials. A material’s toughness refers to the amount of energyneeded to break it. Strength refers to a material’s ability to carry a load (重量).Take a ceramic (陶瓷的) plate, for example. It can carry quite a bit of food to the dinnertable, but if you drop it on the floor, it breaks. Ceramic plates are strong, not tough. A rubber ball,on the other hand, can easily be squished (挤压) out of shape, but it’s hard to break. Rubber ballsare tough, though not particularly strong.In fact, when it comes to materials, toughness and strength are like the two poles of a magnet(磁铁). For years, it was thought impossible to find materials that are both tough and strong –until now, with the new nanofiber (纳米纤维) created by scientists from the University ofυNebraska-Lincoln, US, reported Live Science.To understand what a nanofiber is, you first have to know about nanotechnology. The “nano” part of “nanotechnology” refers to the size of a nanometer, which is one billionth of a meter.Nanotechnology is the science of controlling matters of extremely small size. But how small arethey? Think of it like this: a piece of paper is ϖ100,000 nanometers thick, and so is your hair.Nanofiber is one type of nanotechnology. To see these fibers, you need a microscope (显微镜) that is many thousands of times more powerful than the ones used in a science class.Despite their small size, nanofibers can still be woven(编织) into materials that are hundredsof times stronger than steel and are very tough at the same time.“If materials were tougher, one could make products more lightweight and still be very safe,”Professor Yuris Dzenis, who led the study, told Live Science.Airplanes, for example, are made of many composite (合成的) materials that, if broken,could lead to terrible crashes. To make up for (补偿)not being tough enough, engineers usemore of these materials, making airplanes safer, but also much heavier. But with the newnanofiber materials, not only planes, but also bridges, bikes can all be made lighter, stronger andtougher.“Whatever is made of composites can benefit from our nanofibers,” Dzenis said.A. To compare nanofibers and composites.B. To introduce the development of nanotechnology.C. To inform us of the characteristics and uses of nanofibers.D. To discuss the toughness and strength of different materials.( ) 42. How does the author explain the meanings of toughness and strength of a material?A. By giving examples.B. By asking questions.C. By making comparisons.D. By analyzing(分析) causes and effects.( ) 43. According to the text, a nanofiber ______.A. is as thick as one of your hairsB. is both tough and strongC. is the toughest material ever foundD. can be seen with a common microscope( ) 44. What does the underlined word “despite” mean?A. 如果B.除非C. 尽管D.由于( ) 45. What can we conclude from the text?A. Composites are stronger but much heavier than nanofibers.B. Nanofibers have potential for a wide range of applications.C. It still remains to be seen whether the nanofiber material is safe to use.D. Whatever is made of composites will one day be made of nanofibers instead.第Ⅱ卷(非选择题,共65分)根据句意,用括号中所给单词的正确形式填空。
