【推荐1】Social media has completely taken over everyday life, affecting how society runs and changing individuals in ways that even they can feel. While social media can act as a platform for people to express themselves, it can also be overwhelming, especially for high school teens.

To teenager Bryson Lan, quitting social media helped eliminate (消除) a significant distraction in his routine and keep up with teachers. “I was scrolling through social networking sites so much,” Lan said. “I was also starting to struggle since I entered my high school year. When school started, I was super overwhelmed (不知所措的), and I was just not ready for it.”

Most teenagers fear that by eliminating these apps, they will miss out on connections with their peers and feel a significant loss to their social life. However, Lan found he didn’t miss anything during his time without social media.

Another problem with social media is the amount of “junk content” posted. People are regularly posting and updating on social media, and much of the content has no meaning to other viewers and is ultimately a time suck.

However, social media isn’t all negative. Social media can be a place to develop passions and boost creativity. For example, Lan found his interest in photography blossom after seeing works from other photographers on social media. “Social media is a good place where you can have a portfolio (作品集) or upload your works,” Lan said. “A lot of people have photography accounts or art accounts. In some ways, I think it actually furthers your hobby.” “Thanks to this revolutionary development of social media, we can enjoy a world where everyone is closer than before,” Lan said. “But we also need to have the skills to make good use of social media, and that depends on each person’s efforts.”

1. What did getting rid of social media bring Lan?

C．A smaller social circle.	D．More attention on his studies.

2. What does the underlined phrase “a time suck” in paragraph 4 mean?

A．A waste of time.

A few years ago, I started to notice big shifts in teens’ behavior. Around 2014, teens started to spend their time much differently from the generations before. These teens and young adults all have one thing in common: Their childhood or adolescence coincided with the rise of the smart phone. For this reason, I call them iGeneration.

What makes iGen different? Growing up with a smartphone has affected nearly every aspect of their lives. They spend so much time on the Internet, texting friends and on social media that they have less leisure time for everything else. Whether it’s going to parties, shopping at the mall, or watching movies, iGen teens are participating in these social activities at a significantly low rate.

Some parents might worry about their teens spending so much time on their phones because it differs from the way they spent their own adolescence. But it is not just different-in many ways, it’s actually worse. Spending less time with friends means less time to develop social skills. A 2016 study found that sixth graders who spent just five days at a camp without using screens ended the time better at reading emotions on others’ faces, suggesting that iGen’s screen-filled lives might cause their social skills to shrink.

In addition, in the annual Monitoring the Future survey, the percentage of iGen teens who read a non required book every day dropped from 60 percent in 1980 to only 16 percent in 2016. Perhaps as a result, average SAT critical reading scores have dropped 14 points since 2010.

iGen shows another break with the previous generations: Depression, anxiety, and loneliness have shot upward with happiness declining. The teen suicide rate increased by more than 50 percent, as did the number of teens with clinical-level depression.

Parents used to worry about their teens spending too much time with their friends-they were a distraction, a bad influence, a waste of time. But it might be just what iGen needs now.

1. How are iGen teens different from the generations before?
_________________________________________________________
2. What is another break with the previous generation does iGen show?
_________________________________________________________
3. Please decide which part is false in the following statement, then underline it and explain why.
Teen’s friends were regarded as a distraction, a bad influence, and a waste of time by most parents, so it’s not suggested that teens spend time with their friends.

4. Can you offer some suggestions for iGen teens? (about 40 words)

【推荐1】The Coalition for the Homeless is an organization that seeks to address the needs of the homeless population in the United States. It is a network of offices, some of which provide food and houses for the homeless population, and some of which fight for the passing of laws that of over two hundred million people living in the United States,up to three million are homeless—and the number is still growing. Since the late 1970s,fast rising house prices,large cuts in government supported housing programs, and economic recession(经济衰退)have made it impossbile for many Americans to meet housing costs. Sadly, this has resulted in a number of persons being forced to leave their homes and/or unable to find new affordable homes. According to another research,families with children appear to be the fastest-growing part of the homeless population, making up 39% of it.The old idea of a homeless person,that of the single man who gets drunk all the time,is no longer true. A much lager part of the population now finds itself homeless. Even worse, once a person becomes homeless, he often finds it impossible to find a job,since most employers require anyone who wants a job from them to provide a home address on a job application.

As science and technology have changed the way adults live, the toys children play with have changed as well. Development in science and technology has had a big effect on the toys that children play with. Today trains and mobile phones are popular toys for young children, but there were no toys of this kind before real trains and mobile phones were invented. The materials that toys are made of have also changed. Today lots of toys are made of plastic. Plastic is a modern, man-made material that did not exist in the past. On the other hand, some other toys that you have might not be all that different from the ones children played with 1,000 years ago. Scientists have found some bone dice（骰子）in Aberdeen. In medieval（中世纪的）times dice were used for playing games as much as they are today.

A recent survey found that half of all the children aged from 4 to 6 have played video games, a quarter of them regularly. The increasing use of electronic toys troubles Dr Singer, a professor at Yale. “One thing we know is that kids in early years need to be in touch with the real world,” he said, “no matter how brilliant they are, they’re not going to learn to walk, to move or to talk to others unless their hands or feet have a direct role in such activities.”

Some toy experts argue that the best toys are the ones that increase a child’s creativity and imagination. Traditional toys can be used for different kinds of purposes and be used in group settings, individually（单独地）, and one-to-one. They are also used differently depending on the child’s age and skill level. And these toys made of natural materials are valuable for children because they teach children what the world is made of.

1. In how many ways do toys change according to the first paragraph?

A．One.

B．Two.

C．Three.

D．Four.

2. The author used the example of “dice” to show that ______.

A．the toys are changing all the time

B．some toys are made of different materials

C．some toys don’t change over time

D．some toys’ materials don’t change over time

3. From the article, we can know that ______.

A．only children like to play with toys

B．toys have nothing to do with children’s future life

C．the development of toys is related to science and technology

D．plastic is the best material for making toys

4. According to Dr Singer, ______.

A．the electronic toys are good for children if they play often enough

B．the electronic toys prevent children keeping in touch with the real world

C．children should play with electronic toys instead of the traditional ones

D．children should be stopped from being hurt by the danger coming from the outside world

【推荐3】Conventional wisdom says that hardship can make us old before our time. In fact, a new study suggests that violence not only leaves long-term scars on children’s bodies, but also changes their DNA, causing changes that are equal to seven to ten years of premature aging.

Scientists measured this by studying the ends of children’s chromosomes (染色体）, called telomeres(端粒), says Idan Shalev, lead author of a study published in Molecular Psychiatry.

Telomeres are special DNA sequences (序列）which prevent the DNA in chromosomes from separating. They get shorter each time a cell divides, until a cell cannot divide any more and dies.

Several factors have been found to shorten telomeres, including smoking, radiation and psychological stresses such as being treated badly when young and taking care of a chronically ill person.

In this study, researchers examined whether exposure to violence could make children’s telomeres shorten faster than normal. They interviewed the mothers of 236 children 3t ages 5, 7 and 10, asking whether the youngsters had been exposed to domestic violence between the mother and her partner; physical maltreatment by an adult; or bullying. Researchers measured the children's telomeres —in cells obtained by wiping the insides of their cheeks一at ages 5 and 10.

Telomeres shortened faster in kids exposed to two or more types of violence, says Shalev. Unless that pattern changes, the study suggests, these kids could be expected to develop diseases of aging, such as heart attacks or memory loss, seven to 10 years earlier than their peers.

Shlev says there is hope for these kids. His study found that, in rare cases, telomeres Better nutrition, exercise and stress reduction are three things that may be able to lengthen telomeres, he says.

The study confirms a small but growing number of studies suggesting that early childhood adversity imprints itself in our chromosomes, says Charles Nelson, a professor of pediatrics and neuroscience at Harvard Medical School.

A．Violence can cause quick cell death in children’s body.

B．Telomeres can help prevent chromosomes from separating.

C．Children who have shorter telomeres have heart attacks later.

D．Being treated badly will make a child’s telomeres shorten faster.
