This is the accepted wisdom inside the book industry —and in many British families, too. Parents and booksellers tend to blame the growing appeal of online entertainment and handheld games, but research from the US is challenging these assumptions. Michael Norris, an American publishing expert, will release findings in the monthly Book Publishing Report which show that, despite the best intentions, it is well-meaning mothers and fathers who often stop their sons and daughters from picking up the reading habit. “Parents have too much of a role in deciding which books their children are going to read,” said Norris. “It is turning children off.” The results of a number of surveys Norris has carried out with hundreds of American book-sellers over the past year have provided the basis for a series of tips for parents designed to help children find enjoyment in books. One of his tips is to make sure children talk directly to a librarian or a bookseller, while parents stand well back. Parents should allow children to choose their own reading material. “Even if a mother or father is just standing with the child when the bookseller asks them what they like to read, we have found that the child will give an answer they think their parent wants to hear. It will not be the same answer they would give alone,” said Norris. Norris’s another tip for parents is that they do not attempt to limit books to one age range. ”What we have found is that parents should not worry whether a title looks too young or too old for a child. If a book has caught their attention, then let them take it.“ Children, added Norris, often enjoy reading books that are easy for them to understand. “My father made me read The Hunt for Red October by Tom Clancy when I was much too young and I have never read another Clancy since,” said Norris. 8. What did Norris think prevents children from enjoying reading? A. Children’s interest in handheld games. B. The declining market of the book industry. C. Parents influence on children’s book selection. D. The growing popularity of online entertainment. 9. What do we learn about the new study? A. It’s published to improve book sales. B. It mainly focuses on British families. C. It involves many years’ efforts. D. It was conducted by Norris. 10. What should parents do to help kids get their favourite books at bookstores? A. Introduce new books regularly. B. Let them talk with booksellers alone. C. Discuss popular books with children. D. Often seek expert advice from booksellers. 11. What did Norris think of his father’s act? A. It was totally wrong. B. It was quite necessary. C. It aroused his interest in reading. D. It showed parents’ worries about kids. D While it may sound like something that has crawled out of your nightmares, cyborg cockroaches (蟑螂) have arrived as friends rather than foes. Scientists have designed a new remote controlled insect, equipped with a battery “backpack” that is powered by solar panels. The cockroach, which is part insect and part machine, is intended to enter dangerous areas, monitor the environment or undertake search and rescue missions without being recharged. The researchers had to install some components into a tiny pack to allow for the cockroach’s natural movements. The cockroaches are still alive, but sensory organs attached to the end of their bodies send electrical impulses that cause the insect to move right or left. A battery is necessary for the sending and receiving of these electrical signals, which needs to be charged up. While it’s possible to build docking stations for recharging the battery, they need to return and it could disrupt time-sensitive missions. To solve the tough problem, the team wanted to create a more practical version that does not need to return to a docking station when it runs out of power. Therefore, they designed an on-board solar cell that could continuously ensure that the cockroach stays charged while it works. However, cockroaches have a limited surface area available for all the components necessary to move its legs and keep it powered. The solution was to design a special “backpack” that could neatly carry both the wireless leg-control module and rechargeable battery. This was attached to the top of the insect on its front, and was 3D printed to fit perfectly to the curved surface of cockroach. It allowed for this electronic device to be stably fixed on the insect for over a month, while leaving enough space to implant the solar panel. Famously able to survive a nuclear war, cockroaches have been the inspiration for a number of technologies in recent years. Different teams of scientists have designed remote-controlled robo-bugs that can climb walls, carry objects and find humans during search-and-rescue missions. 12. What is a cyborg cockroach? A. A tiny backpack with a solar panel. B. A robot working as a power station. C. A kind of bug discovered by scientists. D. An insect remote-controlled by humans. 13. What is a big challenge to create cyborg cockroaches? A. The components are too small. B. Recharging can delay urgent tasks. C. Sending electrical impulses is dangerous. D. Their organs can’t receive signals timely. 14. What do we know about the cyborg cockroaches in paragraph 4? A. The special backpack is fixed on their legs. B. 3D printing solves all problems perfectly. C. They have a limited surface to store power. D. They can still get charged while working. 15. What is the best title of the passage? A. A Solar Powered Cockroach B. The Future of Rescue Mission C. New Recharged Solar Panels D.

(虽然可以建造对接站为电池充电，但它们需要返回，这可能会打乱时间敏感的任务。为了解决这个棘手的问题，该团队希望创造一个更实用的版本，在电源耗尽时不需要返回坞站)”可知，制造电子蟑螂的最大挑战是充电会延迟紧急任务。故选B。 【14题详解】 细节理解题。根据倒数第二段中“Therefore, they designed an on-board solar cell that could continuously ensure that the cockroach stays charged while it works.(因此，他们设计了一种机载太阳能电池，可以持续确保蟑螂在工作时保持充电状态)”可知，半机械蟑螂在工作时仍然可以充电。故选D。 【15题详解】 主旨大意题。根据第一段中“Scientists have designed a new remote controlled insect, equipped with a battery “backpack” that is powered by solar panels.(科学家们设计了一种新的遥控昆虫，它配有一个由太阳能电池板供电的电池“背包”)”结合文章主要介绍了“太阳能蟑螂”，这种蟑螂半昆虫半机器，用来进入危险区域、监测环境或执行搜索和救援任务而不需要充电。文章介绍了其工作方式以及作用。由此可知，A选项“太阳能蟑螂”最符合文章标题。故选A。 9/9 学科网（北京）股份有限公司 $$
