2 . Social network Facebook has announced that it is pausing work on Instagram Kids, a young people’s version of Instagram, the photo and video-sharing app that Facebook owns. Instagram Kids would have been for 10 to 12-year-olds, who cannot officially use Instagram because it has an age limit of 13.

However, Facebook has recently been criticized for the effect that Instagram can have on teenagers’ mental health, and in particular how girls feel about their bodies.

Facebook has since published its own research which suggests that Instagram more often has a positive effect. However, the criticism has made the company decide that now is a bad time to develop the app for people who are younger than teenagers.

Adam Mosseri, the boss of the Instagram, said that this would give the company time to listen to and work with parents, experts, public officials and politicians and to show that Instagram Kids would take into account concerns around the mental health and wellbeing of its users.

Instagram Kids has not been completely cancelled, but if it is eventually launched in the future, you’ll need a parent or guardian’s permission to sign up. There will be no advertisements and you will only be able to access “age-appropriate” photos and videos.

Mosseri said that he understood people’s worries about the project and that these steps should help the company to get things right. However, several US politicians have called on Instagram not to restart work on the app. “A pause is not enough,” said a statement from four politicians who are keenly opposed to Instagram Kids. “Facebook has completely given up the benefit of the doubt when it comes to protecting young people online and it must completely abandon this project,” the statement said.

3 . Electronic media such as email, instant messaging, video games, and television, has influenced almost every aspect of our daily lives.     1     While some media exposure can be useful and informative (增进知识的), too much screen time takes away from other activities.

Screen time becomes a particularly important issue when discussing children’s use of media. Experts now recommend children’s screen time should be limited to no more than 2 hours per day, including television and non—school related computer usage.     2    

Unfortunately, it appears that this recommendation is not followed in most families. One recent study found that children between the ages of 8 and 18 spend nearly 45 hours per week watching television, playing video games, and surfing the Internet.     3     Besides, much of the electronic media that makes up children’s screen time is filled with inappropriate (不合适的)   contents.

    4     First, never allow televisions and computers in your child’s bedroom. Avoid using television, video games, and computer time as a reward for good behavior. Provide plenty of other recreational activities for your child to enjoy and set a good example for your child with regard to your own media usage.

It’s important to serve as a model of healthy electronics use for your children.     5     Keeping the TV on for background noise all the time and scrolling (滚屏) through your phone any time will teach your child bad habits.

A．Most children know more about electronics than adults do.

C．Parents should think of ways to manage their children’s screen time.

D．This is more time than they spend doing homework, or reading for pleasure.

E．However, the effect of being all the time in front of a screen is not entirely positive.

F．So before you watch your favorite TV series, remember to set a good example.

G．Children under the age of 2 are generally encouraged to have no screen time at all.
