Teens who become addicted to their cell phones may be placing their health at risk by harming their ability to sleep well,a new Swedish study suggests.

"The message is that teenagers who use their cell phones excessively are much more stressed, much more restless, much more tired, and have a great tendency to develop sleep deprivation(剝奪) as a result of their calling habits, " said the study author Dr. Gaby Bader.

He focused on the experiences of 21 healthy Swedish boys and girls between the ages of 14 and 20. The teens kept what the authors described as "regular working/studying hours" and were not previously diagnosed with any particular sleep irregularity.

He observed that the above-15 call group kept more irregular sleeping hours than the lower-use group,had more difficulty falling asleep,more difficulty waking up,and experienced more sleep disruptions(擾亂).

Bader said that among young people,a relatively recent technological invention like the cell phone has quickly become existed nearly everywhere,giving rise to considerable pressure to keep in touch. And this pressure can develop into an addiction,with serious negative results for teenager health.

"We see more and more people--especially the young generation-- who grew up with these kinds of items and gadgets in their hands," Bader said. "And they become dependent on the technology. So,we have to teach young people to be structured. To know when to have the cell phone on,and when to switch it off. To avoid becoming the slave of technology,instead of the master. "

Dr. Mary Carskadon expressed little surprise with the finding. " Interpersonal(人際的)contact is one of the things that's best at keeping us awake," she observed. "And so,a young person receiving cell phone texts or phone calls is going to have more deep disturbances. And they are going to be tired and restless,and probably,as a result,going to use more stimulants(興奮劑).And judgment is not always the best in our teenage years. So, that's where I think parental attention to this issue may be useful. "

72. Teens who become addicted to their cell phones will become     .

A. too anxious to relax.               B. unable to stay still.

C. unable to have real rest.             D. excited to forget sleep.

73. What we can learn from the sixth paragraph is that     .

A. more teens know how to make technology serve them

B. teens used to be taught how to use technology

C. we should make use of technology rather than be in the control of it

D. the young generation depends less on the technology to grow up

74. According to Dr. Mary Carskadon,how to deal with the problem?

A. Teenagers should judge how to use their phones.

B. Teenagers should reduce their interpersonal contact.

C. Teenagers should switch their phones off.

D. Parents should give more attention to children's use of phones.

75.What's the passage mainly about?

A. Too much phone time has a bad effect on teens' sleep.

B. Too many cell phone calls have cost teens too much.

C. Few cell phone calls will damage teens' friendships.

D. Too little cell phone time improves teens' attention at class.

High school dropouts(輟學者)earn an average of $ 9,000 less per year than graduates. Now a new study dispels a common belief why they quit. It’s much more basic than flunking out(不及格).

Society tends to think of high school dropouts as kids who just can’t cut it. They are lazy,and perhaps not two bright.So researchers were surprised when they asked more than 450 kids who quit school about why they left.

“The vast majority actually had passing grades and they were confident that they could have graduated from high school.” John Bridgeland, the executive researcher said. About 1 million teens leave school each year. Only about half of African-American and Hispanic(美籍西班牙的)students will receive a diploma(證書),and actually all dropouts come to regret their decision. So, if failing grades don’t explain why these kids quit, what does? Again,John Bridgeland:"The most dependable finding was that they were bored.” “They found classes uninteresting; they weren’t inspired or motivated. They didn’t see any direct connection between what they were learning in the classroom to their own lives, or to their career aspirations.”

The study found that most teens who do drop out wait until they turn sixteen, which happens to be the age at which most states allow students to quit. In the US,only one state,New Mexico,has a law requiring teenagers to stay in high school until they graduate. Only four states: California, Tennessee, Texas and Utah, plus the District of Columbia, require school attendance until age 18, no exceptions, another researcher,says raising the compulsory attendance age may be one way to keep more kids in school.

“As these dropouts look back,they realize they’ve made a mistake. And anything that sort of gives these people an extra push to stick it out and it through to the end, is probably helpful measure.”

New Hampshire may be the next state to raise its school attendance age to 18. But critics say that forcing the students unwilling to continue their studies to stay in school misses the point-the need for reform. It's been called for to reinvent high school education to make it more challenging and relevant, and to ensure that kids who do stick it out receive a diploma that actually means something.  

68. Most high school students drop out of school because          .

A. they have failing grades     

B. they take no interest in classes

C. they are discriminated against    

D. they are lazy and not intelligent

69. The underlined words “stick it out” probably means“         ”.

A. complete schooling                 B. solve the problem

C. love having classes                         D. believe in themselves

70. In the last paragraph, the writer is trying to          .

A. analyze the reason why students quit school

B. suggest raising the compulsory attendance age

C. raise awareness of reforming high school education

D. wish to make laws to guarantee no education

71. From the passage,we can infer the following EXCEPT that          .

A. the grades of most dropouts at school were acceptable

B. about 500, 000 high school dropouts are black and Spanish

C. classes don't appeal to dropouts

D. on average dropouts cannot get good jobs

For years we have been told that encouraging a child’s self-respect is important to his or her success in life. But child experts are now learning that too much praise can lead to the opposite effect, Praise-aholic kids who expect it at every turn may become teens who seek the same kind of approval from their friends when asked if they want to go in the backseat of the car.

   The implication (含義) of saying “You are the prettiest girl in class,” or talking about the goals she scored but not her overall( 全面的) efforts, is that you love her only when she looks the best, scores the highest, achieves the most. And this carries over to the classroom.

   Social psychologist Carol Dweck, PhD, tested the effects of overpraise on 400 fifth grades while she was at Columbia University. She found that kids praised for “trying hard” did better on the tests and were more likely to take on difficult assignments than those praised for being “smart”.

   “ Praising attributes (品質) or abilities makes a false promise that success will come to you because you have that quality, and it devalues efforts, so children are afraid to take on challenges, ” says Dweck, now at Stanford University. “They figure they’d better quit while they’ re ahead.”

1.The underlined words “ Praise-aholic kids” refer to kids who are _______.

A. tired of being praised

B. worthy of being praised

C. very proud of being praised

D extremely fond of being praised.

2.The author quoted (引用) Dr. Dweck’s words in the last paragraph in order to make the article ______.

A. better-known                          B. better-organized

C. more believable                            D. more interesting

3.We can infer from the passage that ____________.

A. praise for efforts should be more encouraged

B. praise for results works better than praise for efforts

C. praising a child’s achievements benefits his or her success in life.

D. praising a child’s abilities encourages him or her to take on challenges

Zoe, Damacela, 19, didn't have nice clothes when she was young. It wasn't easy for Zoe’s hard-working single mother to make ends meet. They moved in and out of homeless shelters.

Everything changed for Zoe in grade nine. At that time, she heard about a sewing(縫紉) class at her school. She signed up and couldn't wait to turn her designs into clothes. The color of the first dress she made was white-black strips. Soon the clothes she wore were all made by her. Other girls at school loved her designs too. They asked her if they could buy dresses from her. Zoe sold her first dress for $13. Unfortunately, it cost her $25 to make the dress. “I had the creativity in designs," says Zoe. “But I really had no idea about business.”

Zoe kept selling the clothes she designed. Her business was booming, and even the girls who had ever teased her became her customers. In the eleventh grade, Zoe took a business class. She learned how to price her clothes so that she could be sure to make a fair profit.

Her business teacher suggested she take part in a contest for teenaged entrepreneurs (企業(yè)家). The contest was for teens from all over the United States. Zoe sent in her business plan, which explained how she planned to make her company grow. She won the second prize in the end. Zoe ’s success became a news item. Supermodel Tyra Banks heard about it and she invited Zoe to take part in her TV show. “Being recognized I felt really unreal,”says Zoe.

Vans, Keds, Dollies—they sound like the names of rock bands, but if you have teenagers, you'll know they're actually the latest in teenage footwear.

But experts are now warning that the current shoe fashions will be causing teenagers discomfort in the short term and storing up years of foot, knee and back pain in the future.

Here, the experts identify the problems caused by teenagers' shoe choice.

KEDS/VANS

Slip-on shoes with elastic (彈性的)sides are particularly popular among teenage boys - with Keds and Vans the most sought-after brands.

The main problem is that they are just too flat—so flat that the heel, which strikes the ground first, also becomes damaged and painful.

BALLET PUMPS

The worst shoes of all are such light and thin dolly shoes. The problem is partly their flatness, as with Keds and Vans. However ballet pumps, which have no string or heel, have other specific problems.

“As the shoe has no fastening device, it relies on the toes to keep the shoe on, causing an awkward gait(步法), this leads to short- and long-term problems such as calluses(繭子), heel and knee pain.”

WEDGES AND STILETTOS

These shoes can also cause problems with gait. They may look good, but the heels on these are so high they can force the wearer's body weight forward, making them very unstable.

Teens who wear these shoes regularly are also in danger of joining those millions of women with constant back pain.

SCHOOL SHOES

So what do podiatrists(足科醫(yī)生)have on their wish list, especially for everyday wear?

Something in a natural, breathable fabric, with a string to hold it on, with a small heel and a deep toe-box that does not press the toes, such as Clark's, Marks & Spencer or Rhino.

If your teen insists on wearing 'bad' shoes, get them some simple foot orthotics(矯形器) in the shoes. These support and correct the movement of the foot and, properly fitted by a podiatrist, can often transform their walk and halt the damage.

 

1. Of all the shoes mentioned in the passage, which can cause the worst problems?

  A. Marks & Spencer.                       B. Wedges & Stilettos.   

C. Keds and Vans.                     D. Ballet Pumps.

2. Which pair of shoes may not be found on the podiatrists’ wish list?

 

                                         

 

3. The underlined word “halt” in the last paragraph probably means _______.

A. increase           B. worsen           C. stop           D. cure

4. From this passage we can infer _______.

  A. trendy shoes may ruin teenagers’ health

B. fashionable shoes all have orthotics in them

  C. experts are strongly against wearing popular shoes

  D. podiatrists are expert at producing branded shoes

5. In which column of Mail Online can you find this passage?

  A. Sports.          B. Science.           C. Health.             D. Shopping.
