Cell Phones: Hang Up or Keep Talking

Millions of people are using cell phones today. In many places, it is actually considered unusual not to use one.1. They find that the phones are more than a means of communication – having mobile phone shows that they are cool and connected.

The explosions around the world in mobile phone use make some health professionals worried. Some doctors are concerned that in the future many people may suffer health problems from the use of mobile phones. Mobile phone companies are worried about the negative publicity(負(fù)面報(bào)道)of such ideas. 2.

On the other hand, signs of change in the issues of the brain and head can be detected with modern scanning equipment. In one case, a traveling salesman had to retire at a young age because of serious memory loss. 3. This man used to talk on his mobile phone for about six hours a day, every day of his working week, for a couple of years.

4. The answer is radiation(輻射). High-tech machines can detect very small amounts of radiation from mobile phones. Mobile phone companies agree that there is some radiation, but they say the amount is too small to worry about.

As the discussion about the safety continues, it appears that it’s best to use mobile phones less often.

Every year, TIME selects the best inventions that are making the world better, smarter and — in some cases—a little more fun. Here’s which ones made this year’s unranked list.

●Morpher

People refuse to wear a helmet because they’re thick and bulky. Morpher, a bike helmet made from interweaved plastics that is just as strong as its traditional helmets, but flexible enough to fold almost totally flat, making it easier to transport. Morpher has raised almost $300,000 on Indiegogo and may be available for sale in stores in future.

● Hyper Adapt

Almost everyone who sees the movie Back to the Future wants a pair of self-lacing shoes. Now, thanks to Nike, the shoe dream is a reality. When wearers press a button near the tongue, the Hyper Adapt 1.0s automatically tighten and loosen around their foot. Simplified shoe fastening could give users an edge during sports competition, and it’s especially useful for people with impaired(受損的) motor function.

●Hello Sense

It's hard to believe that an alarm clock could not only be beautiful but also improve your sleep. That it could monitor the temperature, humidity(濕度), light and even air quality in your bedroom to help you engineer a perfect sleep environment. That it could monitor your sleep cycles and wake you when you’re least likely to feel groggy—all thanks to simple voice commands.

●Eatwell Assistive Tableware

It is hard for Alzheimer’s patients to use silverware without spilling. Eatwell Assistive Tableware is a dining set designed to make mealtime easier for people with Alzheimer’s and other diseases that affect brain and body function.

A handshake is one of the most common ways to greet others, but US President Donald Trump’s unusual method has been put under the microscope lately.

Much like an arm wrestler in a match, the recently-elected leader has a habit of yanking (猛拉) people’s hands toward himself during handshakes. And while a typical handshake is only brief, the one between him and Japanese Prime Minister Shinzo Abe on Feb 10 lasted a full 19 seconds.

Simply having a strong hand is not the explanation here. According to Darren Stanton, a body language expert from the UK, while handshakes are usually an exchange of kindness, Trump uses his as a way to show power and control, regardless of how uncomfortable it makes people. “It is as if to say, ‘Hey, I’m in charge, don’t mess with me,’ ” Stanton told The Independent.

Apart from Trump’s “yank-shake”, there are other ways people display power with their hands. At business talks or political meetings, for example, some people may rotate (旋轉(zhuǎn)) their wrists during handshakes so that their hand ends up on top instead of underneath. Some may squeeze so hard that it leaves the other person’s hand in pain.

According to Stanton, by pulling people into his personal space, Trump is also testing whether they are willing to cooperate with him. “For example, if someone was resistant to being yanked towards him and stood their ground, he would know that he has work to do with them before he got what he wanted,” Stanton told Express.

This is probably why on Feb 13 when Canadian Prime Minister Justin Trudeau visited the White House, all eyes were on how he was going to handle Trump’s handshake. Fortunately, Trudeau managed to avoid the embarrassment by grabbing Trump’s shoulder to stop himself being pulled in. Afterward, some Twitter users wrote that this proved Trudeau’s strong leadership, with one even calling the moment “one of Canada’s greatest victories”.

Vice magazine summed up the exchange between the two leaders as: “... no regular handshake. This was the first shot in a bloodless war.”

1.According to Darren Stanton, Trump uses his “yank-shake” to _____.

a. show his kindness

b. gain control

c. remind people of his status

d. see if people are cooperative

e. get people to lower their guard

A. bcd B. abc

C. ace D. bde

2.The phrase “stood their ground” in Paragraph 5 probably means _____.

A. going ahead B. standing still

C. turning around D. pulling out

3.According to the text, the way Trudeau reacted to Trump’s handshake _____.

A. annoyed Trump B. displayed his power

C. was considered rude D. was likely to start a war

4.What can be concluded from the text?

A. Some people spin their wrists during handshakes to show extra respect.

B. Handshakes are the most preferable way for political leaders to greet others.

C. The way someone shakes another person’s hand can have different meanings.

D. The longer two people shake their hands, the better their relationship is.

"I didn't hear them call my name," explained Shelley Hennig to Active Teens (AT) as she talked about that exciting moment on national television when she won the honor of Miss Teen USA 2004. "Are you ready?" is what she heard. Then she said, "I shook my head no, and then they said 'yes' and it was announced again."

It was four days after that life changing moment for the seventeen-year-old high school student from Destrehan, Louisiana -- she was still on cloud nine.

"I was so shocked! I never believed that it could actually really happen." Present in the audience that day were: her mother and father, older brother, her friends, and her dance teacher.

Understanding why members of her family and her friends would be there, AT asked why her dance teacher had traveled so far to see her compete. "She's always been my role model. I've danced with her since I was six. She's been through so many difficulties and came through them all. I've learned to get over bad life's experiences and learned how to move on because of her."

One of those bad life's experiences for Shelley happened three years ago when her brother Brad was killed in a drunk driving accident. He was 18. She found writing helped her get through the rough days. She said, "I write a lot about my brother. I write a lot, a lot, a lot..."

As Miss Louisiana Teen, she traveled around the state speaking to teens about the dangers of drinking and driving. In her role as Miss Teen USA, Shelley will continue to speak to youth about safe driving, in addition to many other things to help the youth.

When AT asked Miss Teen USA if she had any advice for our readers, she said, "Don't let anyone change you. Hang out with people that make you feel good about yourself. That way, it is easy to be yourself."

1.What do the words "on cloud nine" in Paragraph 2 probably mean?

A. frightened B. troubled

C. very happy D. very angry

2.Shelley takes her dance teachers as a role model mainly because she is ________.

A. determined B. friendly

C. strict D. experienced

3.What suggestion does Shelley give to the teens?

A. Be yourself with the support of friends.

B. Meet friends whenever possible.

C. Go easy on yourself and others.

D. Have a good role model.
