Nowadays, more and more teenagers use smart phones, tablets and other mobile devices more than ever before. And the amount of time they spend on these devices is only likely to increase in the future. But are all these changes good?

We sometimes call children who are able to use mobile devices and technology easily digital natives. They can text, email, get Wi-Fi, and download. Some experts say that long periods of time spent chatting to friends online, playing video games and listening to mp3s, for example, may possibly change how their brains work.

Then there is the question of privacy. All this online activity creates a digital footprint. Every time we share a photo or a post on social media, and every time we search for something on the Internet, information about our activity is stored somewhere.

Our inability to control what happens to our children's digital footprint and their personal privacy has big possibilities. It might become normal for companies to ask their employees for their social media qualifications. We are also becoming more aware that companies and governments may be able to 'listen in' on our communications. So it is important to make our children aware of the possible results of over sharing.

Another area where the digital world may have a big effect is in education. One worry is that kids who spend a lot of time online at home are sometimes unable to socialize properly with other children when they are at school. Other experts point out that, when it comes to children and technology, the children are the experts, not the teachers. They say that we should stop seeing online as 'bad' and offline as 'good' and there is evidence of innovative work in some schools.

So, do we really need to rescue our children from the dangers of the digital world?

1. Which of the following can summarize the main idea of the text?

A. Do we need to rescue our kids from the digital world?

B. Should children learn to use digital technology?

C. Are there changes in children’s school life?

D. Should teachers accept changes in our life?

2.According to the second paragraph, what is the possible effect of digital childhood?

A. Children can grow up quickly.

B. Children can read texts fluently.

C. Children’s way of thinking may be changed.

D. Children may become mentally disabled.

3.All the following may happen to our digital footprints EXCEPT________

A. When surfing the Internet, our digital footprints are saved.

B. Some business societies may take advantage of the information.

C. Government may look into our communication through the Internet.

D. Digital pictures may be printed by our computer automatically.

4.Why are many teachers doubtful about digital technology?

A. Because some students can not do well in studies.

B. Because some teachers haven’t changed for years.

C. Because some students addicted to digital technology can not socialize well.

D. Because some teachers addicted to tradition technology cannot teach well.

Did you know that almost 100% of the materials in your mobile phone can be recovered and recycled to generate energy or make new products, such as plastic products, electronics or even jewelry? Every mobile phone contains significant amounts of copper, aluminum, gold, plastic and other non-metals that can be recycled and reused.

The Singtel x SingPost E-waste Recycling Programme, launched on World Environment Day, 5 June 2017, is a cooperation between the two leading ICT and postal companies as part of their environmental sustainability efforts.

Called ReCYCLE, the programme provides the means for people to do their part for the environment by recycling their mobile and internet related electronic waste such as mobile phones and chargers, laptops and tablets, modems and routers, and other related accessories(配件).

These unwanted devices can be dropped off into the ReCYCLE bins at selected Singtel Shop and Singtel Exclusive Retailer outlets and Post Offices. You can also ask for a ReCYCLE envelope from any Singtel Shop and Singtel Exclusive Retailer outlets, and Post Offices, and mail your mobile device and accessories at no charge.

This programme reduces waste as it ensures that the valuable metals and components the devices contain get recovered. However, e-waste that is often thrown away, including all the precious metals that it contains, will be burnt and landfilled at Semakau Landfill.

Is the data in my e-waste safe when sent for recycling?

We assured that all storage media devices like SIM cards, memory cards, USB flash drives and hard drives are safe for recycling. Cimelia, our e-waste recycling partner is a reliable and NEA-licensed company, which are only interested in extracting(提取) the precious metals from the devices, NOT the data in them.
