题目内容
The designer asked _______ we were getting on well with the project.
- A.how
- B.what
- C.if
- D.that
试题分析:句意:设计师问是否我们的计划进行的很顺利。how怎样;what什么;if是否;that在从句中没有意义。根据句意故选C。
考点:考查连词的用法。
点评:本题难度适中。连词是近几年高考常考的语法项目,主要考查的是它们的用法及意义,还需正确理解句意及正确分析句子的成分才能做出正确的判断。本题考生容易误选A,主要根据语言环境来判断。
即学即练:All the dishes in this menu,_________ otherwise stated, will serve two to three people.
A. as B. if C. though D. unless
解析:D。句意:除非有特别的说明,要不然这个菜单上的所有的菜只供两到三个人食用。unless表示“如果不……,除非……”,符合句意。
Changing the design of a new product may ______ the risk of its production in the market.
| A.bring about | B.come about | C.bring up | D.come up |
A team of engineers at Harvard University has been inspired by Nature to create the first robotic fly. The mechanical fly has become a platform for a series of new high-tech integrated systems. Designed to do what a fly does naturally, the tiny machine is the size of a fat housefly. Its mini wings allow it to stay in the air and perform controlled flight tasks.
“It’s extremely important for us to think about this as a whole system and not just the sum of a bunch of individual components (元件),” said Robert Wood, the Harvard engineering professor who has been working on the robotic fly project for over a decade. A few years ago, his team got the go-ahead to start piecing together the components. “The added difficulty with a project like this is that actually none of those components are off the shelf and so we have to develop them all on our own,” he said.
They engineered a series of systems to start and drive the robotic fly. “The seemingly simple system which just moves the wings has a number of interdependencies on the individual components, each of which individually has to perform well, but then has to be matched well to everything it’s connected to,” said Wood. The flight device was built into a set of power, computation, sensing and control systems. Wood says the success of the project proves that the flying robot with these tiny components can be built and manufactured.
While this first robotic flyer is linked to a small, off-board power source, the goal is eventually to equip it with a built-in power source, so that it might someday perform data-gathering work at rescue sites, in farmers’ fields or on the battlefield. “Basically it should be able to take off, land and fly around,” he said.
Wood says the design offers a new way to study flight mechanics and control at insect-scale. Yet, the power, sensing and computation technologies on board could have much broader applications. “You can start thinking about using them to answer open scientific questions, you know, to study biology in ways that would be difficult with the animals, but using these robots instead,” he said. “So there are a lot of technologies and open interesting scientific questions that are really what drives us on a day to day basis.”
