Recently, one of my friends have sent me a short message, say that true friends are one soul in two bodies, which moves me very much and makes me think how true friendship is.
Nowadays, the word friendship has been used very often that it has lost its meaning. Some jokingly put it that friends are made to be taken advantage. In my opinion, true friendship doesn’t mean that you need your friends help, you’ll treat them to dinner. True friendship is the communication of the hearts and understand of the souls. True friends keep you in the mind, no matter where they are. Once you have found such true friends, do treasure him. With friendship, life proves happily and harmonious.

It’s normal for teens to want to stay connected to friends and social circles, but in the middle of the night? The Journal of Youth Studies recently published new research indicating that one in five teens from 12 to 15 regularly wake during the night to have some form of social media. Not surprisingly, the research also indicated that these social night owls were three times more likely than their friends to feel tired at school and that girls were more likely than boys to be called to office.
The blue light produced by cell phones, tablets and computers signals the brain to stay awake, so it’s easy to see why a teen might be up all might. A 2016 study in Psychological Science noted the same brain circuits(脑回路)that are activated by eating chocolate and winning money are activated when teens see large numbers of “likes” on their posts or those of their peers.
Besides not catching enough snaps, by interrupting their sleep cycle, teens may never fully engage in REM sleep(快速动眼睡眠), the deepest stage of sleep that may be responsible for brain development and learning.
Considering about 72 percent of children from 6 to 17 sleep with some electronic media in their bedrooms, parents need to set boundaries sooner rather than later.
“Providing access to devices and thus to social media is a privilege that children can earn and also lose, ” Janie Feldman, a psychologist who treats sleep disorders, reminds parents that, “temporarily removing privileges can have important impact so long as the means of earning back the privileges is clear. Teens and parents should discuss and agree upon terms of use, timing, and access. Teenagers are most cooperative when they agree to the rules, so including them in defining rules makes for very effective parenting.
1.What does the new research indicate about teens from 12 to 15?
A. Some of them rely on social media for homework.
B. Some of them share their sleep experience online.
C. Some of them often use cell phones or tablets at midnight.
D. Some of them surf online for ways to protect animals.
2.How will teens’ brain react when they see many “likes” on their posts?
A. It will become too active for the teens to go to sleep.
B. It will inspire the teens to post something more online.
C. It will promote the teens for some restful time.
D. It will promote the teens to earn money with their posts.
3.What advice does Janie Feldman give parents of teens?
A. Forbid their children from using social media at night.
B. Get the children to have the right to social media with housework.
C. Never give the children access to social media if they break a rule.
D. Give back children’s media access when they correct their errors.
4.Which of the following is the best title for the passage?
A. How to Win Back the Trust of Parents
B. Sleep Disorders and Social Media
C. REM Sleep and Brain Development
D. The Harm of Social Media on Teens
