It’s normal for teens to want to stay connected with friends and social circle, but what about that happening in the middle of the night? The Journal of Youth Studies recently published new research showing that one in five teens from 12 to 15 regularly wake to spend all night on social media (社会媒体). Not surprisingly, the research also showed that these social night owls were three times more likely than others 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 and computers makes the brain to stay awake, so it's easy to see why a teen might be up all night. A study in Psychological Science showed the same brain reaction: when teens saw large numbers of “likes” on their posts, they stayed awake with excitement as if they had eaten chocolates or won money. Besides not catching up on sleep and interrupting their sleep cycle, teens may never fully enter deep 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 rules sooner rather than later.
“Providing access (使用机会) to social media is a favor that children can earn and also lose,” Janie Feldman, an expert who treats sleep disorders (紊乱), reminds parents, “The bad effect is clear. So teens and parents should discuss and agree on its use, timing and access. When teenagers agree to the rules, it’s easier for parents to control how much time they use the phones or computers.”

A.Girls often called to office.
B.Teens who stay up late on social media.
C.Teens who are busy with their homework at night.
D.Boys regularly waking in the middle of the night.
2.How do teens react when seeing many “likes” on their posts according to the study?
A.They are too excited to go to sleep.

Animal experts say one of the world's most beautiful and rare kinds of big cat is close to disappearing from the wild. A study earlier this year found that about thirty Amur leopards (豹) still live free. The cats are also called Far Eastern leopards.
Recently, their number has been reduced by one, Some person shot a female Amur, then beat her to death. The animal's body was discovered last month in the Barsovy National Wildlife Refuge in eastern Russia.
An official of the World Wildlife Fund, Darron, said this was the third such killing in the area in the past fives years. Mr, Collins said the death of even one adult female is a huge loss for the endangered cat, He noted that the killing reduces the possibility for cubs (幼兽) or young.
It is not clear how many Amur leopards still live free. One population count was performed in February and March. Wildlife expert Dmitry Pikuuov led this study. It found evidence of seven to nine males. The study identified three to seven females without cubs, Four leopards were identified as females with cubs. In all, five or six cubs were recorded, Six to eight animals could not be identified.
Most of the land where the Amur leopard once lived was in China.New roads and climate change there threatened the animals. So did hunters who kill big cats for their body parts.
Mr. Pikuuov says adult Amurs need about five hundred square kilometers with good forests to survive. He said they also need a large and continuing supply of animals like deer for food. He believes the answer to saving the Amur leopard is for governments to provide protected spaces for wildlife.

An 8-year-old Nigerian, Tani Adewumis, whose family is homeless, won first place at the New York State chess championship without a single defeat at the beginning of 2019 and he says he is not done yet.
“I want to be the youngest grandmaster,” Tani told The New York Times. Tani placed first in the tournament for kindergarten through third grade — an outstanding win for anyone. “It’s unheard of for any kid, let alone one in a homeless shelter,” said Russell Makofsky, who is in charge of the chess program.
Tani hasn’t had an easy life. His family left northern Nigeria in 2017 fearing attacks on Christians, and moved to New York City over a year ago where the boy learned how to play chess at school. School chess coach Shawn Martinez saw Tani’s potential after observing him stand out in the game a few weeks after first learning it early last year. He reached out to Tani’s family about joining in the school’s chess program, and learned they were unable to pay costs associated with membership. Shawn decided to abandon Tani’s fees, which can easily reach thousands with travel and chess camp admissions.
Seven victories later, the elementary school boy is one of the top players in the country for his age group. “He works very hard at his game,” Martinez said, believing Tani could achieve master status in the next year or two. The world’s youngest grandmaster qualified at the age of 12.
As Tani’s story hits national headlines, more people want to help. Makofsky, who set up a GoFundMe for Tani, said the family has received offers for a car, legal services, jobs and even housing. “My hope is that he’ll be in a home tonight,” Makofsky said.
