请品读以下三条关于perseverance (坚持不懈) 的名言 (quote),选择一条谈谈你对此的理解;并结合一个具体事例,说明perseverance的重要性。

A. When the world says, "Give up", Hope whispers," Try it one more time."

B. You can't go through life quitting everything. If you are going to achieve anything, you've got to stick with something.

C. Don't be discouraged. It's often the last key in the bunch that opens the lock.

1. 文中不得透漏个人姓名和学校名称。

2. 词数为100-120左右。

 

见解析

【解析】

A句意:当世界说,“放弃”,希望低语,“尝试再一次。

B句意:你不能在生活中去放弃一切。如果你想实现什么,你必须坚持做某事。

C句意:不要气馁。它通常在打开锁最后一把钥匙。

参考范文:

Perseverance is what it takes to achieve one's success. Without perseverance, one may find it hard to realize his dream.

Personally, I prefer quote A, which asks us not to give up but stick with what we're pursuing. Only by trying again and again can we make it at last.

Take Madam Curie for example. To fulfill her academic ambition, she overcame many hardships to go abroad for further education. After her husband's death, she carried on her research work despite a lot of difficulties. Finally, her continuous efforts paid off. She was awarded two Nobel prizes.

So, never give up easily when faced with failure. Hold on to your dream and you'll surely enjoy a sense of achievement.

Scientists have created a way to control a robot with signals from human brain.By generating the proper brainwaves—picked up by a cap with electrodes (电极) that sense the signals and reflect a person’s instructions—scientists can instruct a humanoid(类人的) robot to move to specific locations and pick up certain objects.

The commands are limited to moving forward,picking up one of two objects and bringing it to one of two locations.The researchers have achieved 94 percent accuracy between the thought commands and the robot’s movements.

“This is really a proof?of?concept demonstration,” said Rajesh Rao,a researcher from the University of Washington who leads the project.“It suggests that one day we might be able to use semi?autonomous robots for such jobs as helping disabled people or performing routine tasks in a person’s home.”

The person wearing the electrode cap watches the robot’s movements on a computer screen through two cameras installed on and above the robot.

When the robot’s cameras see the objects that are to be picked up they pass on the information to the user’s computer screen.Each object lights up randomly on the computer screen.When a person wants something picked up and it happens to light up,the brain registers surprise and sends this brain activity to the computer and then to the robot.The robot then proceeds to pick up the object.

A similar algorithm(计算程序) is used to decide where the robot will go.

“One of the important things about this demonstration is that we’re using a ‘noisy’ brain signal to control the robot,” Rao said.“That means we can only obtain brain signals indirectly from sensors on the surface of the head,not where they are generated deep in the brain.As a result,the user can only generate high?level commands such as indicating which object to pick up or which location to go to,and the robot needs to be autonomous enough to be able to execute such commands.”

In the future,the researchers hope to make the robots more adaptive to the environment by having them carry out more complex commands.
