What is a "lightsaber"? Is it the same as a "tractor beam"?(用英文回答，不要太長）暑假作業…?

A "lightsaber"=sabre is a heavy "light sword" with a lighting blade which is projecting a brightly lit energy blade as a combat weapon ,Or deflect,and re-directing of Blaster Bolts, used in the weapon world of fencing in Holliwood movies.
The tractor section is connected by a flexible joint so that the tractor beam can turn corners more easily in weapon world of fencing as shown in Holliwood movies. It has the ability to make and attract one object to another position from a remote-control distance.

你是學什的?暑假作業怎麼這麼難!
