一But ______ .

A. you didn’t                B. you hadn’t                C. he wasn’t          D. you aren’t 

 

A 【解析】     试题分析:考查动词时态。前句是对过去情况的虚拟,由此可知答语中应该用一般过去时表示过去的事实,根据前句动词would have taken 可知此处用动词did代替take,答案选A。句意:--对不起!如果我知道他病的厉害,我就带他去医院了。--但是你没有。 考点:考查动词时态。

Look, this is the first plane in the world to be created using the new technology of “3D printing”. The airplane was built using only a computer—but it can fly at a speed of 100mph and has a two-meter wingspan.

         It was produced using a special nylon laser printer that builds up something layer-by-layer. The parts were made separately and attached using a “snap fit” technique so the aircraft could be put together without tools in minutes.

         No fasteners at all were used in the manufacture of the plane. Unmanned and electrically powered, the plane can travel in near silence and is also equipped with a small autopilot system. The special production process used is known as “laser sintering (激光烧结)”and allows the designers to create shapes and structures that would normally include costly manufacturing techniques. This technology allows a highly-tailored aircraft to be developed from your own design to first flight in days, while using traditional materials and techniques would take months. And because no tooling is required for manufacture, major changes to the shape and scale of the aircraft can be made with no extra cost.

         Professor Jim Scanlon, who led the team, said, “The process allows the design team to revisit historical techniques and ideas that would have been too expensive using traditional manufacturing.” He added, “This form of structure is very firm and lightweight, but very complex. If it was manufactured traditionally it would require a large number of individually tailored parts that would have to be connected or fastened at great expense.”

         The new printed plane is known as the Southampton University Laser Sintered Aircraft—or SULSA for short—and is part of a wider project using cutting-edge manufacturing techniques. The University of Southampton has been at the leading position of Unmanned Aerial Vehicle development since the early 1990s.

1.Which of the following would be the best title for the text?

A. Revolutionary Breakthrough of 3D Printer

Scientists Create Aircraft with High Speed

C. New Designed Airplane with New Techniques.

D. The World’s first 3-D printed Airplane, SULSA

2.How could the plane work while flying?

A. It should be controlled by an autopilot system.

B. It should be controlled by “laser sintering”.

C. A pilot controls it using a remote control.

D. A pilot with high techniques controlled it.

3.This kind of plane has the following advantages EXCEPT ______.

A. it produces little noise while flying

B. it is manufactured in quite a short time

C. it only requires simple and cheap tools

D. it needn’t extra cost if changes are made

4.Professor Jim Scanlon believes they can _____ with their techniques.

A.produce firmer and lighter real planes easily

B.connect and fasten tailor parts for real planes

C.copy earlier planes to study their techniques

D.find differences by studying the traditional ones
