A smart phone’s low battery warning is the only warning that most people take seriously. Try the following steps and you will improve your battery life.

1. Let there be less light

For larger smart phones, the longer the screen is on and the brighter it is, the faster your battery goes. Try making the screen as dark as you can bear it and still read a text. Darkening the screen is common among teenagers, but it may be hard for Mom and Dad to see what’s showing on their phone.

2. Turn off the signals

Your smart phone does a lot of communicating in the background. They’re checking for things like new emails, text messages, Wi-Fi signals, Bluetooth signals, your location and more. These activities do drain your battery life, so you should turn off whatever you aren’t using. Location Services is also another feature that burns up your battery, so you can use GPS and Wi-Fi to find out which apps have access to Location Services and turn them off.

3. Turn off notifications (通告)

Another way to improve battery life is to stop the constant flow of notifications and updates from Facebook, email, games and sites. Your phone will automatically pick up these notifications when it’s connected to the Internet, and they can have a noticeable impact on battery life.

4. Use battery saving mode (模式)

For a quick way to improve your battery, simply put your smart phone in Airplane Mode. If Airplane Mode is too limiting, some phones have a specific battery saver mode. This shuts down unimportant functions and apps like Wi-Fi, some updates and more.

If used properly, these tips above will improve your battery life up to 30 percent.

1.The underlined word “drain” means “　　　　　 ”.

A. light up　　　　 B. use up

C. pick up　　　　　　 D. make up

2.If you want to improve your battery life, you are advised to use a 　　　　 .

A. small screen　　　　 B. large screen

C. bright screen　 　 D. round screen

3.We can infer that aged people tend to　　　　　 .

A. email family members　　　　　　　　 B. use Location Services

C. darken the screen　　　　　　　　　　 D. brighten the screen

4.We can learn that Airplane Mode can 　　　　 .

A. improve signals　 B. waste energy

The first thing I do in the mornings is look at my phone. That's mainly because my phone is my alarm clock, but once my eyes are open and that screen is lit up in my hands, it's an awfully short trip to check emails and pursue headlines. There's no reason for me to doing this. My emails that early in the morning are mainly junk, and the headlines won't change much before I' ve brushed my teeth and poured a cup of coffee, right?

My wife says I'm addicted to my phone, I disagree, but I can definitely stand to spend less time looking at it. I'm not terribly active on social media, but I do enjoy me some idle scrolling. And, wow, do these tech companies know how to keep those thumbs constantly swiping up? We've got a daughter. and while I think we're pretty good about limiting her screen time, it would seem that technology has fascinated me from the start. So, I decided to try loosening my phone's grasp on my attention by switching the screen to black and white.

Changing the display to black and white is very easy.　 In your iPhone's settings(设置) , choose General(通用功能) , then Accessibility(辅助功能).　 Next choose Display Accommodations(显示调节) , then Color Filters(滤镜).　 Tap the toggle(切换器)　 on and a list of filters appears.

Choose Grayscale and you're all set.

Picture the scene: the battery on your mobile phone has run out． You can't make any calls for help and no one can contact you． You are all alone - well, not quite． Just reach into your pocket and take out a piece of sugar．Put it into the battery, wait a minute, and you're back on the phone．

    Thanks to a couple of American scientists, this situation could become real．Swadesh Chaudhuri and Derek Lovely have invented the"bacteria battery" - powered by bacteria that eats sugar and turns it into electricity．

"This is a special organism," Lovely said．"You can harvest enough electricity to power a cell phone battery for about four days from a spoonful of sugar．"

In the past, bacteria batteries have been expensive and not long-lasting． But this battery uses more efficient bacteria that can turn 80 percent of sugar into electrical energy． This is 30 percent more than similar batteries can manage．

The bacteria battery could become as small as a household battery． It's also cheap and stable, as sugar can be taken from waste and crops．

But the sugar to electricity process is slow: it could take weeks for the bacteria to digest a cup of sugar．And it produces "greenhouse" gases which pollute the environment．

The scientists understand there is a lot more work to be done． "It is still young," said Lovely．"Where we are now is where solar power was 200r 30 years ago．"

But he believes the battery could be used in scientific equipment at the bottom of the ocean．Other ideas include using sugar in the blood to run medical devices in the human body, and taking sugar from animal waste to provide energy to power homes in rural areas．

1.This passage is mainly about_　　　　　 ．

A． how to change sugar into electricity

B． a scientific invention of a new kind of bacteria battery

C． a new way to reduce pollution caused by mobile phones

D． a new kind of mobile phones and its future

2.Which of the following is not the strong point of the newly-developed battery?

A． Convenient．　　　 B．Stable．　　　　 C． Inexpensive．　　　 D． Quick．

3.The underlined sentence in the 7th paragraph actually means　　　　　　 ．

A． the bacteria battery shares some similarities with solar energy

B． scientists will continue their work until they find solar power

C． there is much room for the improvement of the bacteria battery

D． the bacteria battery will get popular in 20 0r 30 years

4.According to the passage, who will find the bacteria battery less useful?

A． Farmers．　　　　 B． Divers．　　　 C． Doctors．　　　　 D． Electricians．

Before you throw that old cell phone in the trash，or hide it away in a drawer，think again. There are actually many ways to dispose(处理)of a mobile phone that you are no longer using. First，you should be aware that in many places，throwing away cell phones is actually illegal because the batteries—especially in very old phones—can contain poisonous metals. 1.

You certainly don’t need to pay to recycle an old cell phone. 2. This had led to many charities making a small amount of money by collecting old phones. There are large organizations that will take unwanted phones. However，you might also want to think locally.

3. And they do make a little bit on each donation. If you can’t find a large cell phone recycling program in your area，you might consider starting a small local one，perhaps for a local public schoo1. 4. As people move to bigger and better phones，or smaller and better phones，there are plenty of old cell phones just waiting for a place to land，and smart schools have provided that place.

You might also want to hang onto any accessories(配件)that you have. 5. Continuing to use accessories in good shape makes smart economic sense.

A.In fact，most companies that recycle them get paid to do so.

B.There are better places to get rid of them than your trash can.

C.Many schools and local charities now have recycling programs.

D.Local charities have contributed a lot in repairing unwanted phones.

E.Things like chargers or covers can often be used with your new phone.
