[20巧郑州一模] We use robots for tasks like building cars and sorting mails,but can we use them as stand-up comedians (单日相声演员) in the fu?ture? One robot called RoboThespian has been trying out some jokes.

Researchers from Queen University of London organized Robothespian's performances to test whether it could be as funny as a human.

The electronic comedian went on stage for a show with British comedians An?drew O'Neill and Tieman Douieb,performing the same jokes as Douieb but with a few changes―it is a robot after all. The robot has some advantages over human comedians,too.

"We used computer vision and audio software to notice the response of each au?dience member,something a human comedian cannot do”， said Kleomenis Katevas,the robot's programmer. "The machine used this information to decide who to look at and which gestures to use.” The robot also has other advantages over human comedians. Impressions of other people and sounds are very popular ways for performers to get laughs,and according to New Scientist reporter Celeste Biever? the robot can perform recorded sound by simply playing it back. It can also act out programmed pieces from Shake?speare or just about anything else.

Another of the robot's advantages is more surprising. Because I feel less em?pathy (同感) for RoboThespian than for the human comedians,I feel more relaxed during his performances," Biever added. And of course,RoboThespian is unlikely to feel as nervous as other comedians,or be affected too badly by an audience member shouting at it.

The Queen Mary researchers say they're most interested in how audiences can be part of live performances. So in the future,we may be watching robots perform?ing exactly the show we want to see. Do you think it's time for the robot to write some more jokes?

1. Why was RoboThespian originally developed?

A. To help human comedians perform better on stage.

B. To find out if robots could understand human jokes.

C. To see if robots could perform like human comedians.

D. To assist human comedians to make up some better jokes.

2. When RoboThespian gave performances on stage,it .

A. imitated the audience's voices to make them laugh

B. was affected easily by an audience member shouting at it

C. performed completely different jokes from human comedians

D. recorded each audience member's reaction and acted accordingly

3. What does Celeste Biever think of robot comedians?

A. He believes the future of comedy lies in them.

B. He considers their jokes as rather poor and boring.

C. He thinks they aren't suitable for live performances.

D. He feels more comfortable watching their performances.

4. What is the article mainly talking about?

A. The robot comedian RoboThespian and its advantages.

B. Robot technology used to help us with our daily tasks.

C. Predictions of the comedy of the future and concern about it.

D. A comparison between human comedians and robot comedians.

[2015河南洛阳第二次统一检测] It is 7 am and the alarm is going off. You know you have to be out of bed to catch the bus. But the urge to bury yourself in the bed is ever so strong. Sounds familiar? Why is it that teens find it difficult to get themselves out of bed in time every morning or stay sharp and focused during the first couple of hours of school?

During adolescence,the body goes through many changes and this includes a shift in sleep patterns. Re?searchers from MIT have been tracking the body's need for sleep in teenagers. They found that though adolescents need as much as 9. 5 hours of sleep a day,they get to bed later and later with each passing year. In fact,the sleep cycle shifts later by as much as 12 to 18 minutes each year between the ages of 10 and 20!So by the time a 10-year-old child who sleeps at 8 pm grows to be 17 or 18,his body naturally wants to stay up till 10:30 or 11pm.

According to researchers,this is because of a hor?mone called melatonin (褪黑激素) that is secreted (分泌) by the pineal gland—a tiny structure deep inside the brain. Melatonin regulates the body's natural day-night rhythms. It causes a person to become sleepy by lowering their body's core temperature. In teens， melatonin is se?creted much later in the evening and continues to increase throughout the night. This makes it difficult for teens to fall asleep earlier as they did in their younger years. Like-wise,the effect of melatonin continues until much later in the morning,making it hard for them to wake up early.

A study found that at least one in four teens is tired and falls asleep in school at least once a week. During sleep,important body functions and brain activities hap?pen. So how can teenagers get their sleep enough? The A-merican Association of Pediatrics (AAP) recommends that middle and high schools should start later―not before 8:30 am. This should give teens some more time to sleep at night.

20. From Paragraph 2,we can learn that if you sleep late,the next day you should .

A. stay sharp B. skip breakfast

C. get up late D. stay up late

21.What does the underlined word "this" in Paragraph 3 refer to?

D. The adolescents sleep late.

22. The teens go to sleep later than before because .

A. melatonin is secreted much later

B. melatonin regulates the sleep time

C. they sleep a lot in the daytime
