2 . It’s a small step for Steve, but could this be a great progress in paralysis(瘫痪)？

Steve’s arms and legs were paralyzed after a fall four years ago. But when he’s wearing this robotic suit, he can use his thoughts to move again.

Learning to walk came quite quickly, but using the exoskeleton(外骨骼) to correctly bend and stretch his arms or turn his wrists took much longer.

So how does the exoskeleton work? Well, first Steve has electric device on the surface of his brain. They are reading his thoughts, his brain activity, his brainwaves, and they are being sent to a computer. Now, the computer has to receive that information at once and change that brain activity into orders, which are sent to the exoskeleton. From thought to movement, it takes less than a third of a second.

Steve first used this electric device in his brain to control a computer game before trying the exoskeleton. Now the French researchers plan to test the technology on three more patients.

This experimental exoskeleton is not going to become widely used soon. If you look, Steve’s body is connected to the ceiling of the room to stop him falling over. It means the exoskeleton can’t be used outside the lab. And it is also too expensive for most of the world to benefit. But this is still a breakthrough and shows the potential of technology to change lives.

This summer has been full     1     unforgettable moments. Among them, Su Bingtian, 31, set     2     new Asian record of 9.83 seconds at the Tokyo Olympics semifinals (半决赛) on Aug 1^st. This     3     (make) him the first Chinese player to qualify (获得资格) for the final in the event.     4     (late), he finished sixth in the final with a time of 9.98 seconds.     5     he missed out on a medal, Su’s performance deserves(值得) cheer     6     respect. He has been working onwards and upwards (勇往直前) to achieve his longtime goal to run in the 100m final in the Olympics. In 2015, Su became the first Chinese     7     (run) in under 10 seconds. But his career was in trouble in the following years because of     8     (injure). He had planned to retire (退休；退役) in 2017, but the call to challenge     9     (he) brought Su back on the field. Now, in his third Olympic Games, Su’s excellent performance spoke for itself. “I hope my performance today serves as an inspiration (鼓舞) for younger players in their sporting careers,” Su told Xinhua. “When I was their age, my speed was no match for them. With the techniques (技巧) and ideas they have, they could achieve much more     10     I have.”
