课下作业（三）高考语篇提能练

Ⅰ.阅读理解

Cellphones are still absent from most U．S. schools but new data shows they are steadily gaining approval.More school administrators are bowing to parents' wishes to stay in touch with their kids.Teachers also find ways to work them into lessons.The nation's largest school system, New York City, is among those that have abandoned strict bans.

Liz Kolb, an education technology professor at the University of Michigan, said, “We've seen a lot of schools say, ‘Well, I'm not going to fight parents that are upset that their child can't have the cellphone in school.’”

“Teachers are also taking advantage of the technology，” Kolb added.Many districts are spending millions of dollars in giving students access to tablets or laptop computers.These have countless academic apps and programs teachers can use.According to Kolb, there are teachers who have found that having the cellphone is like having a computer in your pocket, so it's a way to have another learning tool that isn't necessarily costing the district more money.

Still, some school districts are moving in the opposite direction.The school board in Mansfield City, Ohio, last year tightened its rules.It now requires the devices (设备) be turned off and out of sight in classrooms unless the teacher says otherwise.

In Connecticut, Seymour High School Principal Jim Freund said teachers tried to limit cellphone use to lunch and other noninstructional (非教学的) times.However, students were still playing games or on social media when they shouldn't have been.“I don't think they had the maturity level to control it，” Freund said.So the school promulgated a strict ban in December.Since then, students have reported getting more work done in study hall and the cafeteria has become noisy as students talk to one another more.
