A new robot can jump three times higher than any other robot that its builders know of. It also out - jumps any living creature.
Many researchers studied how animals jump. But Elliot Hawkes’ team didn’t want to copy animals. Instead, they learned what features set limits on animal jumpers and found ways around those limits.
Muscles provide energy for many animals to jump. As they stretch, muscles and tendons (腱) store energy. They release it as they move back to their normal length. The stored energy propels the jump. But a muscle can only tense and release once per jump. Most animal jumpers develop large motors (muscles) and small springs (tendons).　　　　　　　　 　　　　　　
A robot jumper can use a small motor and a large spring because it can use a latch(弹簧锁) to keep the spring in place. With each jump, the spring stretches a bit more. The motor’s power gets multiplied over many jumps as it is stored in the spring. Hawkes’ team used this type of system to maximize how high a robot can jump.
The new robot has two types of springs. As its legs bend, rubber bands connected to them also stretch. By the time the robot is ready to jump, it has a round shape. When the latch releases, the legs and rubber bands snap(啪地合上) back into a narrow shape similar to a model rocket. Then the robot shoots up at nearly 100 kilometers per hour. When the robot lands, it can position itself for the next jump.
“I’m impressed with how high the robot can jump,” says Cynthia Sung, a scientist not involved in the study. “But it needs some improvements. It can’t control its jump height or direction.” Her team has made its own jumping robot named REBOund. That robot can’t jump very high. But it can be programmed to jump to different heights.
Hawkes’ team is working to add steering to its robot. They also want to find a way for it to collect samples on the moon. They hope to turn it into a space explorer.
8. What does the underlined word “propels” in paragraph 3 mean?
A. Drives.
B. Limits.
C. Balances.
D. Explains.
9. How did Hawkes’ team maximize the height their robot could jump to?
A. By helping it store enough energy in advance.
B. By helping it multiply power from many jumps.
C. By equipping it with multiple power engines.
D. By applying excellent animal jumpers’ type of system.
10. What does Hawkes’ robot look like when it’s shooting upward?
A. An arrow.
B. A flat board.
C. A round ball.
D. A model rocket.
11. What is an advantage of REBOund compared to Hawkes’ robot?
A. It is a special space explorer.
B. It can change its jump direction freely.
C. It can control the jump height.
D. It is connected with a computer.

答案： 8.A 词义猜测题。根据画线词所在段的第一句“Muscles provide energy for many animals to jump.”可知，肌肉能够为许多动物的跳跃提供能量。由此可知，肌肉储存的能量能够“驱动”跳跃。drive意为“驱动；驱使”，与画线词意义相近。
9.B 细节理解题。根据第四段最后两句“The motor’s power gets multiplied over many jumps as it is stored in the spring. Hawkes’ team used this type of system to maximize how high a robot can jump.”可知，Hawkes的团队通过帮助机器人储存多次跳跃的能量使这款机器人的弹跳高度最大化。
10.D 细节理解题。根据第五段第四、五句“When the latch releases, the legs and rubber bands snap back into a narrow shape similar to a model rocket. Then the robot shoots up at nearly 100 kilometers per hour.”可知，当弹簧锁松开时，腿和橡皮筋会弹回一个类似火箭模型的形状，然后机器人以每小时近100千米的速度向上弹起。由此可知，机器人在向上弹起的过程中像一个火箭模型。
11.C 推理判断题。根据倒数第二段中的“But it needs some improvements. It can’t control its jump height or direction.”和“Her team has made its own jumping robot named REBOund. That robot can’t jump very high. But it can be programmed to jump to different heights.”可知，Cynthia Sung提到Hawkes的团队研发的机器人无法控制其弹跳高度和方向。而她的团队研发的名为REBOund的弹跳机器人虽然弹跳得没有那么高，但它能跳到不同的高度。由此可推知，REBOund的一个优势是它可以控制弹跳高度。
