It is often the case, when having meals, waiting buses or at tending lectures, you can always find people addicted to their cellphones, completely ignoring others.

This is really a common phenomenon in our daily life. The reason is why smart phones nowadays can be used to playing mobile games and keep in touch with friends. However, too much exposure to phones are bad for people in terms of healthy. Moreover, people involving in phones fail to communicate well with these around them.

As far as I am concerned , people should be wisely make use of their phones to help with their work and study. Meanwhile, they should care much about their family and friends than mobile phones.

3 . Instagram（图片分享社交应用程序）is about to take its biggest step toward removing likes from its platform. After months of testing an option to hide likes in select international markets, Instagram, which is owned by Facebook（FB）, has already been testing hiding likes in seven other countries, including Canada, Ireland and Australia. For years, likes have been central to how celebrities, brands, politicians and everyday users experience Instagram and Facebook. It's a way of measuring popularity and success. But in recent months, Instagram has been rethinking how likes contribute to making its platform more toxic. Now it's considering a change.

The total number of likes on posts — which appear as hearts on the app ——will disappear from Instagram's main feed, profile pages and permalink（永久链接）pages. The owner of the account can still see their own likes, but their followers won't know the count.

CNN Business previously spoke with users in countries with the test. The majority felt this move would improve well-being on the app. Instagram is the most detrimental（不利的，有害的）social networking app for young people's mental health, such as negatively impacting body image, according   to one study.

But other users and psychologists said hiding likes won't fix everything. The test doesn't address some of the key ways that activity on Instagram can impact the well-being of users, including bullying, feeling left out and thinking other people's lives are better than their own.

Renee Engeln, a psychology professor at Northwestern University, voiced his opinion that the biggest impact of Instagram is the content and the exposure to this constant stream of perfected images is what seems to hurt psychologically. Plus, users can still see their own likes ——and feel badly if their posts don't perform well.
