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.

It used to be a matter of fact when Peter Pan – a character from James Matthew Barrie’s 1911 book – said: “All children, except one, grow up.”

But this “fact” doesn’t seem to apply to today’s world anymore.

According to the NPD Group, a US market research company, sales of toys to adults in the UK increased by more than 20 percent in 2016, three times the pace of the children’s toy market itself. These toys ranged from puzzles and Lego building sets to vehicle models and action figures. And more than half of the sales came from millennials – people born between the 1980s and 2000s.

“Adults of the 21st century are channeling (疏导) their inner child, one toy at a time,” commented website Koreaboo. This is also why these adults are sometimes referred to as “kidults”.

According to Frederique Tutt, an analyst at NPD, the motivation of these grown-ups is to escape the stress of today’s fast-paced world. They are driven toward the more immediate pleasures brought by toys than those brought by, say, getting a promotion, which is far less easy to achieve.

“It reminds me of the playful side of life,” Rob Willner, a 25-year-old PhD student in the UK, told The Telegraph when talking about his love for Lego, which he said brings him both comfort and entertainment.

Despite this, some social scientists see the trend as disturbing. To Frank Furendi, a professor at the University of Kent in the UK, the fact that so many adults are pursuing “the thrills (刺激) of youth” is the evidence that “adulthood has got nothing attractive about it anymore”, he told The New York Times.u “That’s actually quite sad.”

But scientists are probably just worrying too much. According to Canadian comic book artist Todd McFarlane, collecting toys could simply be a way for people to express their individuality (个性).

“It’s just pop culture stuff. It’s stuff that says, ‘I like a little of this and I like a little of that’,” he told ABC News. “[It’s] no big deal.”

So now that over 100 years have passed since Peter Pan, perhaps it’s time to introduce a new “fact”, as stated in the tagline (品牌宣传词) of the UK fashion brand KIDULT: “Growing old is mandatory (强制性的), but growing up is optional.”

1.The author mentions Peter Pan in the text mainly to ______.

A. show the influence of the character on millennials

B. explore the similarities Peter Pan and millennials share

C. lead up to the trend of millennials’ love for toys

D. analyze what has made many millennials refuse to grow up

2.Why do many adults feel like collecting toys, according to Frederique Tutt?

A. They find it brings them both comfort and inspiration.

B. They consider it a way to relieve stress.

C. They want to make up for the pleasures they missed during childhood.

D. They usually don’t get along well in their lives and need an emotional outlet.

3.What can we conclude from the article about kidults?

A. They are well-known for their pursuit of independence and freedom.

B. Social scientists feel worried about them because they take nothing seriously.

C. In Todd McFarlane’s eyes, their interest in toys is a way to express their identity.

D. They refuse to make efforts to become promoted at work as they don’t want to grow up.

Walking alone in the dark, the boy whistled to________his courage.

A. keep up B. hold up

A Cornell University sleep researcher has some advice for people who run high schools: Don’t start classes so early in the morning. It may not be that the students who nod off at their desks are lazy. And it may not be that their parents have failed to enforce(确保) bedtime. Instead, it may be that biologically these sleepyhead students aren’t used to the early hour.

“Maybe these kids are being asked to rise at the wrong time for their bodies,” says Mary Carskadon, a professor looking at problem of adolescent (青春期的)sleep at Cornell’s School of Medicine.

Carskadon is trying to understand more about the effects of early school time in adolescents. And, at a more basic level, she and her team are trying to learn more about how the biological changes of adolescence affect sleep needs and patterns(方式).

Carskadon says her work suggests that adolescents may need more sleep than they did at childhood, no less, as commonly thought.

Sleep patterns change during adolescence, as any parent of an adolescent can prove. Most adolescents prefer to stay up later at night and sleep later in the morning. But it’s not just a matter of choice—their bodies are going through a change of sleep patterns.

All of this makes the transfer(迁移)from middle school to high school—which may start one hour earlier in the morning—all the more difficult, Carskadon says. With their increased need for sleep and their biological clocks set on the “sleep late, rise late” pattern, adolescents are up against difficulties when they try to be up by 5 or 6 a.m. for a 7:30 a.m. first bell. A short sleep on a desktop may be their body’s way of saying. “I need a timeout.”

______.

A. students work so late at night that they can’t get up early

D. it is really tough for parents to enforce bedtime

2.The underlined phrase “nod off” most probably means “_______”.

A. fall asleep B. turn around

C. agree with others D. refuse to work

3.Which of the following statements is NOT true according to Mary Carskadon?

A. Adolescents are going through a change of sleep patterns.

B. Adolescents need less sleep than they used to at childhood.

C. Adolescents prefer to stay up later at night and sleep later in the morning.

D. It is difficult for adolescents to get up early for a 7:30 a.m. first bell in high school.

4.What is the test mainly about?

A. Adolescent heath care.

B. Adolescent sleep difficulties.

C. Problems in adolescent learning.
