Fix it on your own

Did you know that a bowl of rice could save your iPod if you drop it in a swimming pool by accident? Or that the camera on your phone could tell you what's wrong with your TV remote control? The experts at Geek Squad (geelsquad.co.uk) have made a gadget(小机件) rescue guide. So, let’s take a look at some of their useful advice.

● How to get more juice out of your phone battery(电池)

If your battery goes dead but you need to get a number or send one last text, try warming it up. That may give you a tiny bit of power. Take the battery from the phone and rub it between your hands. Or warm it under your arm for a few minutes. Then try to start the phone – but use it quickly.

● What to do if your gadget gets wet

First, try drying it out with a vacuum cleaner. If a vacuum cleaner isn’t at hand, fill a pot or bowl with uncooked rice and put your we gadget inside. The dry, uncooked rice will absorb all the water and, after a few hours, you should be able to use the gadget. Don’t forget to remove the battery and SIM card before you dry it.

● What to do if your TV remote control stops working

If replacing the batteries doesn’t work, get the camera function up on your phone and point the remote at the lens(镜头). When you press a button on the remote, if it's working then the glass bobble(小球) at the front of the remote will light up when you look at it on the screen of your phone. This is because the screen on a phone or digital camera picks up infrared rays (红外线), even though your eyes don't. If the glass bobble doesn’t light up, the remote is broken. If it does, the receiving device is broken.

43.If your cell phone falls into a sink, you can         .

A.warm it up under your arm.       B.put it into the uncooked rice.

C.press it with both of your hands.    D.remove the battery after you dry it.

44.Why can a phone be used to prove the TV remote control works well?

A.Because it can receive infrared ray.

B.Because it can reflect infrared ray.

C.Because it can improve the TV remote control.

D.Because it can picture the TV remote control.

45.In which section of a newspaper can we possibly read this text?

A.Entertainment     B.Finance        C.Culture       D.Life

46.The purpose of the passage is to give people        .

A.professional guides     B.necessary warnings

C.practical tips              D.personal opinions
