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.

For a year and half, kids sent hurtful messages like “You are ugly.” or “Why are you still alive?” to Rebecca Sedwick. In 2013, Rebecca, then 12, couldn’t stand it anymore. She took her own life near her home in Florida. Soon afterward, Trisha Prabhu read about the story. “I was surprised and heart-broken,” said Trisha, now 15, who is from Naperville, Illinois, “I know that I had to do something to stop this from ever happening again.”

Trisha did some research. Studies show that one fourth to half of all teens in the US have been cyberbullied (网络欺凌). Experts say that if you are ever bullied online, you should tell a trusted adult. Tell the cyberbully to stop, and prevent him or her from contacting you again. Print and save messages to share with the police. This is good advice, agrees Trisha. But these methods all take place after the bullying has already happened. Trisha had a different idea. Why not teach cyberbullies to stop before they post these messages?

Trisha’s research won awards, including a prize in the Google Science Fair. Then, Tresah built the ReThink app (应用软件). It is programmed to recognize words or phrases that could be hurtful. When that happens, different warning messages come out. “Don’t say things that you may regret later!” says one message. Others ask, “Are you sure you want to say this?” and “Are these words really yours?”

Now Trisha is working on a version(版本) of ReThink for computers. “I am a big dreamer,” she says. “I want to stop cyberbullying before the hurt is done.”

1.What do we know about Rebecca Sedwick?

A. She was one of Trisha's best friends.

B. She sent hurtful messages to others.

C. She ended her life at the age of 12.

D. She went to Florida to study further.

2.What is Trisha’s suggestion for stopping cyberbullying?

A. Stop talking with the cyberbully.

B. Stop the messages before they are sent.

C. Turn to your parents or close friends

D. Show the messages to the police at once.

3.What is the third paragraph mainly about?

A. People's attitudes to the ReThink app.

B. Trisha's research on cyberbullying.

C. How the ReThink app works.

D. The Google Science Fair.

4.Which of the following can best describe Trisha?

A. Honest and careful. B. Helpful and clever.

C. Proud and impolite. D. Strange and impatient.
