Forty percent of teens say they have been hit or nearly hit by a car，motorcycle or bike while walking，according to a new report released by the Safe Kids Worldwide organization.

Safe Kids Delaware has released a list of safety tips children and teens should follow in order to remain safe while walking. The group said it is important to put down phones and remove headphones while crossing the street，make eye contact with drivers before crossing，and remain visible to drivers even in the dark.

"We all know about the dangers of distracted（思想不集中的）driving，but we need to talk to our children，especially teens，about the dangers of walking while they are distracted by using technology like listening to music with headphones on，and texting on cellphones，"said Kim O'Malley，the pedestrian（行人）safety conductor for Safe Kids Delaware.

Teens on the Moue is the name of the report，which explores the walking behavior of  1，040 teenagers between the ages of 13 to 19.Half of the surveyed teens admitted they were distracted by a mobile device while crossing the street. The study also found that more often than not，those who were hit or nearly hit had not been using a crosswalk（人行横道）or had been running across the street.

Safe Kids Worldwide reports that the death rate for teens aged 13 to 19 is nearly three times higher than that of 5-to 12-year-olds.In Delaware，seven teenagers aged 15 to 19 have been killed in pedestrian crashes in the last three years，and another 123 have been injured. By comparison，just two children aged 5 to 9 were killed at that time and another 79 were injured. The new report expands on findings from a similar one in 2015 that showed one in five high schoolers and one in eight middle schoolers crossed the street while distracted by using technology.

   A primary school in Jinhua, Zhejiang Province, has announced (宣布) it no longer requires parents to sign their children’s homework. China Youth Daily _____:

Putting an end to the _____ that parents sign off the homework of their children _____ the burden on many parents, as otherwise they would have to look through primary school homework after a hard day’s work. But there are _____ that if parents stop having to sign off their children’s homework, the children will not get _____ grades.

_____, the most efficient way for children to study is to develop their _____ to learn and do their own homework.

When doing homework, students practice and _____ apply what they have learned. Truly, teachers are _____ to check students’ homework and ______ their mistakes. But some parents correct their children’s mistakes by themselves when signing off it.

It is the ______ of students to do their homework, be responsible ______ their studies and correct their mistakes. Parents’ supervising (监督) their homework, checking their answers and ______ the harder problems will only make children ______ aware of their mistakes and encourage them to ______ their parents’ help when they face any problems.

Children have to manage their own learning and ______ the ability to study by themselves, as competency (能力) will not be achieved ______ a student simply repeats fixed ______ in which he is helped in school by teachers and at home by parents.

An experiment ______ by Walter Mischel in the 1960s proved that children with better self-discipline performed better in their studies and interpersonal relationships.

   Every pet owner loves his pet. There is no argument here.

But when we asked our readers whether they would clone their beloved animals，the responses（反应）were split almost down the middle. Of the 228 readers who answered it，108 would clone their beloved animals，111 would not and nine weighed each side without offering an opinion.

Clearly，from readers’responses，this is an issue that reaches deeply into both the joy and eventual sadness of owning a pet. It also shows people’s widely different expectations over the developing scientific procedure.

Most of the respondents who favored the idea strongly believed it would produce at least a close copy of the original；many felt the process would actually return an exact copy. Those on the other side，however，held little hope that cloning could truly recreate a pet；many simply didn’t wish to go against the natural law of life and death.

Both sides expressed equal love for their animals. More than a few respondents owned“the dog/cat in the world”.They thought of their pets as their“best friend”，“a member of the family”，“the light of their life”.They told moving stories of pets’ heroism，intelligence and selfless devotion.

Few wonder the loss is so disturbing（令人不安的）and the cloning so attractive.“People become very close to their animals，and the loss can be just as hard to bear as when a friend or family member dies，”says Gary A. Kowalski，author of Goodbye Friend：Healing Wisdom for Anyone Who Has Ever Lost a Pet. “For me，cloning feels like an attempt to turn death away... It’s understandable. Death is always painful. It’s difficult to deal with it. It’s hard to accept.”

But would cloning reduce the blow? This question seemed to be at the heart of this problem.

   Computer hackers have now got their hands on mobile phones. A phone virus program can get your phone to do things you have no _____ of, computer security experts _____.

It might call the White House or the police, or _____ your personal address book to a marketing company. Or it could simply eat into the phone’s operating software, turning it _____ and erasing your personal information.

Similar viruses have already made mobile phone owners _____ in Japan and Europe.

Mr. Hypponen, chief technical officer of computer security in Finland said, “A virus can get your _____ and send them somewhere else. And it can record your _____.”

Mobiles are now able to _____ the Net, send e-mails and download software. So they easily become the _____ for the same hackers who have sent viruses to computers over the past decade.

“It’s technically ______ now,” said Stephen Trilling, director of research on anti-virus software.

“If the phone is connected to the ______, it can be used to transmit (传递) threats and ______ just as any computer can.”

In Japan, ______ you open a certain e-mail on your mobile, it will cause the phone to repeatedly ______ the national emergency number.

So phone operators will have to ______ emergency calls until the virus is ______.

In Europe, mobiles’ short message service, ______, SMS, has been used to send codes that could damage ______.

“Mobile users can ______ viruses, of course, by ______ their traditional phones without Web links,” some experts say.

Why College Is Not Home

The college years are supposed to be a time for important growth in autonomy(自主性) and the development of adult identity. However, now they are becoming an extended period of adolescence, during which many of today’s students are not shouldered with adult responsibilities.

For previous generations, college was a decisive break from parental control; guidance and support needed to come from people of the same age and from within. In the past two decades, however, continued connection with and dependence on family, thanks to cell phones, email and social media, have increased significantly. Some parents go so far as to help with coursework. Instead of promoting the idea of college as a passage from the shelter of the family to autonomy and adult responsibility, universities have given in to the idea that they should provide the same environment as that of the home.

To prepare for increased autonomy and responsibility, college needs to be a time of exploration and experimentation. This process involves ＂trying on＂ new ways of thinking about oneself both intellectually(在思维方面)and personally. While we should provide ＂safe spaces＂ within colleges, we must also make it safe to express opinions and challenge majority views. Intellectual growth and flexibility are fostered by strict debate and questioning.

Learning to deal with the social world is equally important. Because a college community(群体) differs from the family, many students will struggle to find a sense of belonging. If students rely on administrators to regulate their social behavior and thinking pattern, they are not facing the challenge of finding an identity within a larger and complex community.

Moreover, the tendency for universities to monitor and shape student behavior runs up against another characteristic of young adults: the response to being controlled by their elders. If acceptable social behavior is too strictly defined(规定) and controlled, the insensitive or aggressive behavior that administrators are seeking to minimize may actually be encouraged.

It is not surprising that young people are likely to burst out, particularly when there are reasons to do so. Our generation once joined hands and stood firm at times of national emergency. What is lacking today is the conflict between adolescents’ desire for autonomy and their understanding of an unsafe world. Therefore, there is the desire for their dorms to be replacement homes and not places to experience intellectual growth.

Every college discussion about community values, social climate and behavior should include recognition of the developmental importance of student autonomy and self-regulation, of the necessary tension between safety and self-discovery.
