My granddaughter, Shari, owns The Berry (莓果) Factory in Sacramento, California, and her mother, Joan, and I were helping with the Valentine’s Day rush. We’d dipped (浸泡) hundreds of berries, arranged gift baskets and packaged orders to be shipped around the country.
By the end of the day, the two middle-aged women, Joan and I, were exhausted. Shari didn’t seem tired. That was typical Shari. Though she was very busy, I’d seen her give away berries to everybody — parking attendants, mail carriers and hairdressers. “For me?” they would say, bursting into a smile.
As a “thank you”, Shari took us out for dinner. But there was a 45-minute wait at her favorite restaurant. “No big deal. There’s another place just up the road,” she said, driving us there. This time we walked right in.
When the waitress came to take our drink orders, Shari reached into her handbag, pulling something out. “I want you to have these,” she said, handing the waitress a box of chocolate-dipped strawberries. “She will love those berries!” I thought. But the waitress seemed startled. She only let out a “thank you” before grabbing the box and rushing into the kitchen.
A few minutes later, the waitress returned with our iced tea. “I apologize,” she said. “My best friend and I had promised to send each other something every Valentine’s Day. But she passed away last year. I didn’t know how I’d get through this day without her. Then you handed me that box.”“I’m so sorry to hear that,” said Shari. “It’s not much, but I hope you can enjoy them.”“Oh, I will,” the waitress said. “See, every year we always sent each other the same thing; a box of chocolate-dipped strawberries bought from our favourite store, The Berry Factory.”

It’s 10:30 p.m., and 11-year-old Brandon Blanco is sound asleep at home. Suddenly, a loud noise wakes him up. Naturally, Brandon reaches for his cell phone. He blinks twice, and the message on the screen becomes clear: “R U awake?”

But the late-night text does not annoy Brandon. He gets frequent messages and calls, even after bedtime. And he can’t imagine life without them. “If I didn’t have a cell phone, I wouldn’t be able to talk to my friends or family as often,” he told the Kaiser Family Foundation.

Brandon’s use of technology doesn’t stop there. He also has a computer, a TV and three video-game consoles（控制台）in his room. With so many devices, it is no surprise that when he is not at school, he spends nearly every waking minute using one or more of these devices. Brandon is hardly alone. According to a recent study by TFK, kids aged 8 to 18 are spending more time than ever before using electronic devices. How much time? More than seven and a half hours a day on average, the study found. That’s about an hour more than just five years ago.

The jump is the result of a huge explosion in mobile devices, says Victoria Rideout, the lead author of the study. “These devices have opened up many more opportunities for young people to use media, whether it’s on the bus, on the way to school or waiting in line at the pizza parlor,” says Rideout.

Often, kids multitask, or use more than one device at a time. “If you’ve got a chance to do something on your computer and take a phone call and have the TV on in the background, why not?” Media expert Cheryl Olson says. Most experts agree technology has much to offer kids. But some worry the kids could be missing out on other activities like playing outside or hanging out with friends. “It’s a matter of balance,” says Olson.

Multitasking while doing homework is another concern. Some kids listen to music, watch TV or use the phone while doing their homework. “It’s important to make sure that you can stop and concentrate on one thing deeply,” says Rideout.

With new and exciting devices hitting stores every year, keeping technology use in check is more important than ever. “Kids should try,” adds Rideout. “But parents might have to step in sometimes.”

3.The underlined phrase “in check” in the last paragraph can be replaced by _________.

A. in order         B. in store         C. in control               D. in sight

B. have less homework

C. spend more time on homework
