Step 7 Reading practice

Read the text and answer the questions.

Why did Jan quit her job?

How did the people in the online community help her?

Why did she start the IT club?

What is the "digital divide"?

What's Jan's next goal?

What can we learn from her experiences?

keys:

She suddenly developed a serious illness.

People in the online community talked with her about her problems, supported her, and gave her advice.

To teach older people how to use computers and the Internet.

The digital divide is the gap between those who have access to the Internet and those who haven't, and those who know how to use new technology and those who don't.

Her next goal is to start a charity website to raise money for children in poor countries.

We learn that when we go through tough times, we can find help and support from other people online. We also learn that we can feel less lonely.

List the ways in which the text says that the Internet has changed people's lives. Try to add more examples.

Discuss the questions below in pairs.

Do you think your life has been changed by the Internet? If so, how?

The writer mentions many advantages of using the Internet. Do you think there are any disadvantages? If so, what are they?

keys:

My life has certainly been changed by the Internet. It has made my school work and studying easier and has helped me stay in touch with old friends more easily and often.

I think there are a few disadvantages from using the Internet, such as the lack of privacy. Sharing everything online means people can know everything about us. Also using the Internet all the time distracts us from the real world around us.

Step 8 Read headlines

Headlines usually include only key ideas or information from the text. They often do not follow strict grammar rules, because writers use as few words as possible to catch the attention of the readers.

Step 9Video: The Positive affects the Internet

The teacher shows the video.

Can you list the negative effects of the Internet?

Step 10Difficult sentences

At age 50, she found herself out of work and stuck at home with only her computer to keep her company.

此句结构为“find +宾语+宾补”，out of work和stuck at home是句子的宾语补足语，说明宾语herself 的处境。

“with+名词+to do”结构，在句中做stuck的伴随状语

She believes that it is highly important to bridge the digital divide and make sure that everyone has access to the Internet and knows how to use new technology.

本句中的bridge、divide和access既可以用作名词又可以用作动词。

bridge—般用作名词，本句中作动词，意思是“架起桥梁、消除（隔阂）”。
