High school biology teacher Kelly Chavis knew smartphones were a problem in her class. But not even the students realized how much of a problem the devices were until Chavis did an in-class experiment.
For one class period, students used a whiteboard to count every Snapchat, Instagram, text, call that appeared on their phones. Chavis is among a growing number of teachers, parents and health experts who believe that smartphones are now partly to blame for increasing the levels of student anxiety. “One girl, just during the one hour, got close to 150 Snapchat notifications. 150!” she said.
Jean Twenge, a psychology professor at San Diego State University in California, said it is not a coincidence that youth mental health issues have risen with the number of phones. “This use of phones has led to a loss of sleep and face-to-face interactions necessary for their growth,” she said.
Researchers are still not sure whether phones cause student depression or depression causes phone use. But nearly 60 percent of parents said they worry about the influence of social media on their child’s physical and mental health.
Both schools and parents are starting to take steps to deal with the problem. Many public schools pay outside companies to watch students’ social media activity for signs of anxiety. Other schools invite in yoga teachers and comfort dogs to help calm students.

D.Whether students are willing to give up using phones.
The huge T-rex (霸王龙) bends over a large triceratops (三角龙) lying on his side below. With its mouth open wide, the T-rex looks ready to kill the triceratops with a final bite to the triceratops’s neck. The display will be found at the National Museum of Natural History.
The museum has sought a huge T-rex skeleton (骨架) for many years. Before, it used a model of one. But museum director Kirk Johnson says that was never good enough. “It’s been kind of deeply embarrassing to be the national museum and NOT have a T-rex,” he said. The T-rex display is now the centerpiece of the museum’s newest show, which will be available to the public on July 15.
That T-rex, named Sue, was found in South Dakota. Officials at the museum built a special area for the skeleton. It includes a gift store of all things related to Sue. Sue even has her own Twitter account and a media presentation of her life story.
In modern times, movies like “Jurassic Park (侏罗纪公园)” have helped grow dinosaur interest for a new generation of young fans. But such movies describe the T-rexes as mostly huge, stupid and dangerous animals, which are true threat in the fighting: quick, intelligent and aggressive hunters in groups.
1.What is described in Paragraph 1?
A.How a T-rex hunts in the wild.
B.How a T-rex will be displayed in a museum.
C.How a T-rex is painted in a picture.
D.How a T-rex is filmed in a movie.
2.What do we know about the T-rex skeleton?
A.It was found in Australia.
B.It has been open to the public.
C.It is valued by the museum.
D.It is still a model one.
3.What can be inferred from the last paragraph?
A.Movies about dinosaurs should be reduced.
B.The young generation dislikes dinosaurs.
C.The T-rex is a kind of huge, stupid dinosaur.
D.Some movies are misleading in a way.
