In the picture we can see that Granny Wang is sending an e-mail to her granddaughter, who is studying

in America. Sometimes they even chat face to face online. However, not long ago Granny Wang didn't know

how to send e-mails. If she wanted to see her granddaughter, she had to go to America to visit her in person.

It cost her too much money and took up too much time.

     Then she learned how to use the internet and now it is possible for her to communicate with her

granddaughter easily. She began to use the computer half a year ago. Even though it was hard for her, she

never thought of giving it up. This reminds me of the old saying, it's never too late to learn. Nowadays

everything is changing and developing so fast that if we don't continue to learn new things, we will fall behind

in this fast changing world.
