need to have a mobile phone by our side？

We could start with the advantages of mobile phones. There are many things that we could do with mobile phones. With the advancement of technology，more and more features are being added to the mobile phones which make them more useful. In addition to making calls，mobile phones also support a wide variety of other services such as text messaging，email，Internet access，business applications，gaming and photography. We can bring them everywhere，and can be reached by others anytime. They make the world smaller，bringing people together no matter where they are.

But we could have some risks when using our mobile phones. We may have accidents when we use them while driving. Some studies show that mobile phones can do harm to our bodies;and materials in mobile phones could damage our environment.

Since there are so many risks，why do we still have mobile phones？This is because these risks or disadvantages can be overcome. For example，while we are driving we can easily pull up our car if we really need to use the phone. Mobile phone manufacturers are reducing the radiation of mobile phones to avoid health risks.

Though there are both pros and cons of using mobile phones，we could easily see that there are more advantages than disadvantages. Moreover，mobile phones are becoming cheaper，which might be another reason why mobile phones are increasingly used today.

xt Big Thing turns out to be just a new computer？ This is what I'm asking myself after Apple's 【C1】______ over hyped product introduction. This time around the Next Big Thing is called an iPad.

It's reasonably 【C5】______ , and after spending a few minutes with one, I'm pretty sure I'll buy one for myself and probably 【C6】______ second one for my kids to watch movies on road trips.

That really is "magical" for Apple's bottom line, anyway.

And that's 【C16】______ . What's wrong, or at least interesting, is why some of us 【C17】______ so much more from a new gadget.

We need the magic 【C20】______ .
