No doubt there are ups and downs in life. Whatever the situation is, you shouldn’t lose your joy of life. Life is for a limited period only and no one knows how long he/she will live, so why do you waste your precious time in worrying about the things that are beyond your control? Be happy, and enjoy your life unconditionally (无条件地).

You enjoy good days but you also need to learn how to enjoy bad days, even enjoy your pain. In 2016 when I was in Geneva, Switzerland, I suffered a sudden heart attack. My colleagues called an ambulance and I was taken to hospital with much pain in my chest. Before reaching hospital, I was totally exhausted with pain and was going to lose control of my emotions. Then the doctor in the ambulance said, “Don’t worry; you are in safe hands.” His words took away all my pain because I started realizing that it was no time to worry about pain and it’s time to be happy that my life was safe. At that time, I learnt an important lesson that in pain there is a hidden joy and whoever sees the bright side can enjoy pain. My pain turned into a joy which greatly helped me recover more quickly than expected.

You not only enjoy success but you also need to learn to enjoy failure. Failure provides you with an opportunity to benefit from so many choices you’ve made. Celebrating failure will raise your morale and make you more powerful and determined to achieve success. We all make mistakes in life but only the courageous (勇敢的) people not only laugh at their own mistakes but also let other people laugh at them and then they reach success without any spiritual burden (负担). A person who learns from mistakes and knows how to turn the bad situation into his/her favor is the most intelligent person and really enjoys his/her life.

1.What does the author mainly tell us in the first paragraph?

A.Life is full of ups and downs. B.People’s lives only last a limited period.

C.We should enjoy our life unconditionally. D.Bad situations can be changed into good ones.

2.Why did the author still feel happy when experiencing much pain?

A.His colleagues were always with him.

B.He could be looked after by his parents.

C.He planned to enjoy the last days in life.

D.His doctor made him realize the value of being alive.

3.The underlined word “morale” in Paragraph 3 is closest in meaning to “________”.

A.talent B.confidence

C.pleasure D.inspiration

4.The author thinks that the wisest person________.

A.never laughs at others B.has strong determination

C.is ready to do others a favor D.is good at learning from mistakes

There is no doubt that many parents want to mold (塑造)their child to be better, faster, smarter and more skilled. Even though human parents can’t do that, a robot that builds its own children can. Scientists at the University of Cambridge in England have created a mother robot that not only creates its own children, but tests out their performance.

The mother robot analyzes(分析)the performance of each of the “children” it creates, and passes down good characters to the next generation

For example, as the mother creates them and puts them to work, she measures how they’re behaving, and she uses data from this behavior to create the next generation of robots.

The mother robot can actually build hundreds of child robots and see the performance of these child robots. And if their performance is good, keep their design for the next generation. And if bad, just let it go.

“We program the robots based on some functions that define(规定)the reward the robots are going to get, depending on the construction that they make. They cannot change their own reward. For the child robot, the longer the distance the robot walks, the better the reward it receives,” said Fumiya Iida, the lead researcher.

After several generations, the “children” were running twice as fast.

“The mother robot produced 500 robots to see which one is good and which one is bad,” said Iida.

The researchers believe that the machines can be used in a car factory, for example, where robot cameras examine each ear in production line, find out any mistakes, and then design a better car.

1.What is special about the mother robot?

A. It can analyze data

B. It can create child robots

C. It’s smarter than human mothers

D. It can build and improve its own children.

2.How does the mother robot mold her own children to be better?

A. It teachers them how to behave better.

B. It reprograms the bad ones after analyzing their performance

C. It copies hundreds of child robots and then chooses the best ones.

D. It keeps the good characters for the next generation to create a better robot.

3.What is the key point in influencing the child robot to receive a reward?

A. Size　　 B. Distance.

C. Behavior　　 D. Speed.
