Bicycles, roller skates and skateboards are dangerous. I still have scars (傷疤) on my knees from my childhood run-ins with various wheeled devices. Admittedly, I was a foolish kid, but I’m glad I didn’t spend my childhood trapped indoors to protect me from any injury.

“That which does not kill us makes us stronger.” But parents can’t handle it when teenagers put this theory into practice. And now technology has become the new field for the age-old battle between adults and their freedom-seeking kids.

Locked indoors, unable to get on their bicycles and hang out with their friends, teens have turned to social media and their mobile phones to gossip and socialize with their friends. What they do online often mirrors what they might otherwise do if their mobility weren’t so heavily restricted (限制) in the age of helicopter parenting. Social media and smartphones have become so popular in recent years because teens need a place to call their own. They want the freedom to explore their identity and the world around them. Instead of climbing out of windows, they jump online.

As teens have moved online, parents have projected their fears onto the Internet, imagining all the potential dangers that youth might face.

Rather than helping teens develop strategies (策略) to deal with public life and the potential risks of interacting with others, fearful parents have focused on tracking, monitoring and blocking. These approaches don’t help teens develop the skills they need to manage complex social situations. “Protecting” kids may feel like the right thing to do, but it denies teens the chances of learning as they come of age in a technology-soaked world.

The key to helping youth in the modern digital life isn’t more restrictions. It’s freedom — plus communication. Urban theorist Jane Jacobs used to argue that the safest neighborhoods were those where communities collectively took interest in and paid attention to what happened on the streets. Safety didn’t come from surveillance (監(jiān)視) cameras or keeping everyone indoors but from a collective willingness to watch out for one another and be present as people struggled. The same is true online.

What makes the digital street safe is when teens and adults collectively agree to open their eyes and pay attention, communicate and work together to deal with difficult situations. Teens need the freedom to wander the digital street, but they also need to know that caring adults are behind them and supporting them wherever they go. The first step is to turn off the tracking software. Then ask your kids what they’re doing when they’re online — and why it’s so important to them.

1.When he was a child, the writer ______.

A. became disabled

B. spent much time outdoor

C. always stayed at home

D. was ignored by his parents

2.Teens go online mainly because ______.

A. online games mirror real life

B. they want to fight against their parents

C. online experiences make them strong

D. they need a space of their own

3.By mentioning “helicopter parenting” (Paragraph 3), the writer means parents ______.

A. remove any hidden dangers their kids may face

B. use helicopters to track their kids

C. prevent their kids from going to school

D. protect their kids too much

4.According to the passage, helicopter parents may make kids ______.

A. lose the chances of learning

B. handle complex social situations well

C. adapt to the digital world quickly

D. develop strategies to deal with public life

5.The main idea of the passage is that ______.

A. kids should be given freedom to deal with online risks

B. safe neighborhoods come from joint efforts of all

C. the digital street is a threat to kids’ safety

D. kids should be warned against potential dangers in society

以下是幾本新書的簡要介紹：

A. Strong Is Your Hold

This book was written by Galway Kinnell, who spent many years in finishing the book. Kinnell’s first collection of new poems in more than a decade revisits themes of marriage, friendship and death, with long, loose lines reminiscent of Whitman. It is popular with the people who are interested in literature.

B. The Letter

The murder of a television star appears to be the work of thieves who are quickly caught. But they escape from prison and a young lawyer says she knows who the real criminals are. Written with intelligence, this story is so fast-moving that it demands the reader’s complete attention.

C. London Alive

This author of many famous novels has now turned to writing short stories with great success. The stories tell of Londoners’ daily lives and happen in eighteen different places——for example, one story takes place at a table in a cafe, another in the back of a taxi and another in a hospital.

D. Gone West

A serious look at one of the least-known regions of the United States. The author describes the empty villages which thousands left when they were persuaded by the railway companies to go west in search of new lives. The author manages to provide many interesting details about their history.

E. Cutting for Stone

This book was written by Abraham Verghese. It is a powerful story about twin brothers born in a Catholic hospital in Addis Ababa, Ethiopia. Their mother, an Indian nurse at the hospital, dies in childbirth. The brothers are raised by two Indian doctors who live at the hospital. One brother later moves to the United States. This is a story about the extremes of love, family, and medicine.

F. Jane Eyre

There is great kindness and warmth in this love story. Poor and plain as Jane Eyre is, she has a strong will, sharp wisdom and great courage. She is forced to battle against a harsh employer and a rigid social order. Yet she is never defeated. Standing on her feet, she gains her own happiness in the end.
