If you need to call your parents but your phone is not with you, can you remember their numbers?

To remember 11 numbers is not difficult. However, because of the smartphone, many of us are losing this ability. What's more, smartphones weaken our skills at giving directions, as well as killing face-to-face communications. Even when friends are having a meal together, it's common for most to check their phones.

According to a report, Chinese people spend on average 170 minutes on their smartphones daily.

For students, an addiction（沉溺）to smartphones does no good for studying. Research by Japan's Education Ministry showed children who spend more than four hours a day on their phones perform much worse in school tests than those who play with their phones for 30 minutes.

It's true that the smartphone has made our lives easier. But many also think they spend too much time on it, and this is bad for their study or work.
