Mobile phones have changed the way we communicate, but people disagree on whether the devices are useful tools for education.

Students can be easily distracted by their phones during class. Are they listening to the teacher or texting their friends? Are they taking a picture of a quiz to cheat?

School officials, teachers and parents are all trying to find out the best way to supervise students’ use of mobile or cellphones.

In the Canadian province of Ontario, officials are restricting (限制) phone use during teaching time. However, there are exceptions for classroom activities, health and other emergencies.

France passed a law in 2018 banning (禁止) the use of cellphones in schools for students up to age 15, the age when they go to high school.

Last July, a new law was signed in California. It says state public and charter schools can ban students from using smart phones in class and at school. It does not, however, say schools are required to completely ban the devices. There are exceptions, which include emergencies or problems related to health.

So, the officials turned to technology for answers. San Mateo High School now locks up cell phones during the day in a special container. Each student must put his phone away in small bag with a kind of lock. At the end of the day, students unlock the bag with a device.

Other schools are choosing simpler answers to the problem—they ban cellphones in classrooms. “They wanted to provide a clean break for students and not have the frenetic energy that can happen if kids start texting each other or social-media posts start going,” Behm said.

Education Week found that more than 30 schools, and in some cases school districts, have put in place some kind of restrictions during the current or last school year. Districts across the country also have their own ways of phone restrictions both formal or informal.

Toth said students have grown up with cellphones, and “it is our responsibility to teach them correct use for tools within the classroom.” He added that schools are teaching about cellphones and how to use them with social media and the Internet.

“It is part of changing education for kids,” he said, “as long as we teach them to use them responsibly.”

The technology is here, Toth said, schools should use it to help students, and not fear it.

1.From the passage we can know _________.

A.the students in Ontario aren’t allowed to use mobile phones

B.a high school student can use cellphones in schools in France now

C.bringing smart phones to school breaks the new law in California

D.most people think mobile phones are useful for school education

2.The writer probably agrees ________.

A.students should be banned from using smart phones at any time

B.teachers shouldn’t return students’ cellphones during class break

C.each school finds its own way of cellphone restriction

D.teachers should face the cellphone problem and teach its correct use to them

3.The underlined word “frenetic” probably means ________ in Paragraph 8.

A.wild B.worried C.peaceful D.anxious

4.Which of the following may be the best title of the passage?

A.Should Schools Ban Mobile Phones? B.Do We Need to Change Our Ideas?

C.Best Way to Supervise Students. D.Mobile Phones Belong to Technology.

They tell us when to get up or when we’re running late for work and whether we are in danger of missing our favourite TV programme. But while our daily activities depend on clocks that tell us the time science is discovering that our well-being is influenced by a very different kind of timepiece. Circadian rhythms---the human body’s own internal(体内的) clock—have a powerful influence on our health and behaviour. They are programmed from birth and control functions ranging from temperature and blood pressure to sleep patterns.

In recent years researchers have also discovered that this built-in mechanism (内在机制) can influence everything from the way we react to medicines to how well we learn music.

The latest example, from experts at Harvard University in the US, shows that the human body clock can even influence whether or not we are likely to tell the truth. Researchers found it was easier for people to tell lies in the afternoon because as they were tired, the self control that would normally prevent them from lying started to break down. Tiredness made it easier for them to tell lies ---especially if it meant they got a financial reward at the end.

“The body clock has a great effect on us all,” says Professor Jim Horne from the Sleep Research Centre at Loughborough University. “Most people tend to feel good around late morning and then decline in the early afternoon. But the time most of us will feel our sharpest is between 6pm and 8pm. That’s because sleepiness tends to build up throughout the day. By early evening our body clock kicks in to wake us up. One reason may be to ensure we get home safely. When our ancestors (祖先) were coming home after hunting all day, their internal clocks kicked in to get them home in one piece.”

So what effects do circadian rhythms have and what’s the best time of day to take advantage of them?

1.The underlined word “They” in the first paragraph refers to_____ .

A. our health and behaviour　　 B. scientists and experts

C. our daily routines　　 D. circadian rhythms

2.The research referred to in Paragraph 3 found that people would rather ______ .

A. tell lies when they are tired　　 B. tell lies if they are rewarded

C. get angry as they become tired　　 D. break down because they are tired

3.According to the passage, when are people most quick-thinking?

A. In the morning.　　 B. Around midday.

C. In the late afternoon.　　 D. In the early evening.

4.What information will the writer probably give following the last paragraph?

A. An explanation of how the human body clock controls the body.

B. Examples of how the human body clocks control the body.

C. Examples of the most suitable time to do different activities.

D. Some practical suggestions to prevent people from lying.

Everyone has traits (特性) that make us who we are. We have physical traits, like red hair, long legs and funny-looking toes. We also have character traits including humor, warmth, creativity and so on.

Certain physical traits are fully inherited (遗传), such as blue eyes and knobby knees. About 25,000 to 35,000 genes (基因) are in a single cell in the human body. These genes carry the traits that are passed down genetically from parents to their children.

Many traits exist between inheritance and development — the interaction with environment. One example is body shape. It tends to be passed down from parents. But once diet becomes a factor, environment begins to play an important role in how the body develops. Body shape is a trait that is a mixture of inheritance from parents and influence of environment.

So lots of our most important traits have been learned, rather than inherited. For example, if you’re really great at video games, it’s not because your parents passed down the skills in genes. It’s because you have practiced a lot of video games and developed those skills yourself. If you have kids who turn out to be great at video games, it is because they put in the hours, learned the skills, and memorized the moves that are necessary to play the video games well.

Of course, some of us have brains that are more advantageous to video game playing. Say you were born with a large and powerful part of the brain that controls your hand-eye coordination. That is inherited. What you do with it, how you choose to develop that advantage, is up to you.

You can pierce your nose or get a tattoo (纹身) — it doesn’t matter how much you change your body during the lifetime. None of those things will turn into genetic material to be passed down to the next generation. However, if your children grow up in an environment with role models who are pierced and covered in tattoos, they are more likely to get piercings and tattoos!

1.　　　　　　　　　 is a physical trait that is fully inherited.

A.The eye color B.The special diet

C.The body shape D.The pierced nose

2.What does the underlined word “That ” refer to ?

A.Video game playing. B.Advantageous brains.

C.The shape of your brain. D.Your hand-eye coordination.

3.According to the passage, the writer believes that 　 　　 .

A.character traits can hardly change during the lifetime

B.the skills of video game playing are passed down to kids

C.a kid’s hand-eye coordination isn’t related to inheritance

D.environment plays an important role in traits development

4.Which of the following would be the best title for the passage?

A.Why are Traits Important? B.How does Inheritance Influence Traits?

C.Where do Traits Come from? D.What are Physical and Character Traits?

What makes us who we are? This question has two different answers. One is the environment that surrounds us when we grow up, and the other is our genes (基因). In English, this is called the “nature vs nurture debate(辩论)”. Nature means genes, and nurture means environment, including the people around you.

There is a famous saying: “Give me a child until the age of 7 and I’ll show you the man.” Now, there is a scientific research to support this famous saying.

They watched small birds in new environments, and wrote down how much they explored(探索). Birds that grew up with very outgoing birds were more outgoing themselves. Scientists at the universities of Exeter, UK and Hamburg, Germany did studies on birds. They found that their personalities（个性） were affected most by the birds around them when they grew up – more so than genes.

Nick Royle from the University of Exeter in the UK said the research was surprising because it shows that “for these birds, personality is mainly determined（决定） by environment.” However, human personalities are a lot more complicated than birds, so there is much we still don’t know. The nature vs nurture debate will continue for a long time, if not forever.

1.The famous saying in the passage tells us _________.

A.A 7-year-old boy can do things as well as an adult.

B.An adult can be influenced and changed by a 7-year-old boy.

C.The environment in the early part of our life has the biggest influence on our adult life.

2.Nick Royle is a(n) ______ scientist.

A. American　　 B. British　　 C. German

3.What do the scientists think of the research?

A. Outgoing.　　 B. Exciting.　　 C. Surprising.

4.What does the underlined word “complicated” mean?

A. 有趣的　 B. 类似的 C. 复杂的

5.Which is NOT TRUE according to the passage?

A. The environment and genes affect our personality.

B. The scientists are sure that the environment influences the human personality more than the genes do.

C. The nurture means the environment .
