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

The days of the hunter are almost over in India. This is partly because there is practically nothing left to kill, and partly because some steps have been taken mainly by banning tiger-shooting to protect those animals which still survive.

Some people say that Man is naturally a hunter. I disagree with this view. Surely our earliest forefathers, who at first possessed no weapons, spent their time digging for roots, and were no doubt themselves often hunted by meat-eating animals.

I believe the main reason why the modern hunter kills is that he thinks people will admire his courage in overpowering dangerous animals. Of course, there are some who truly believe that the killing is not really the important thing, and that the chief pleasure lies in the joy of the hunt and the beauty of the wild countryside. There are also those for whom hunting in fact offers a chance to prove themselves and risk death by design; these men go out after dangerous animals like tigers, even if they say they only do it to rid the countryside of a threat. I can respect reasons like these, but they are clearly different from the need to strengthen your high opinion of yourself.

The greatest big-game hunters expressed in their writings something of these finer motives. One of them wrote：

“You must properly respect what you are after and shoot it clearly and on the animal’s own territory (领地).You must fix forever in your mind all the wonders of that particular day. This is better than letting him grow a few years older to be attacked and wounded by his own son and eventually eaten, half alive, by other animals. Hunting is not a cruel and senseless killing — not if you respect the thing you kill, not if you kill to enrich your memories, not if you kill to feed your people.”

I can understand such beliefs, and can compare these hunters with those who hunted lions with spears and bravely caught them by the tail. But this is very different from many tiger-shoots I have seen, in which modern weapons were used. The so-called hunters fired from tall trees or from the backs of trained elephants. Such methods made tigers seem no more dangerous than rabbits.

1.There is no more hunting in India now partly because ________.

A．it is dangerous to hunt there    B．hunting is already out of date

C．hunters want to protect animals  D．there are few animals left to hunt

2.The author thinks modern hunters kill mainly ________.

A．to make the countryside safe     B．to earn people’s admiration

C．to gain power and influence      D．to improve their health

3.What do we learn about the big-game hunters?

A．They hunt old animals.           B．They mistreat animals.

C．They hunt for food.              D．They hunt for money.

4.What is the author’s view on the tiger-shoots he has seen?

A．Modern hunters lack the courage to hunt face-to-face.

B．Modern hunters should use more advanced weapons.

C．Modern hunters like to hunt rabbits instead of tigers.

D．Modern hunters should put their safety first.
