How is a smartphone different from a cell phone，and what makes it so smart? To understand this，we should start with a history lesson． 1. Cell phones were used for making calls while PDAs could store information and a to-do list，and could be linked to your computer．Then PDAs added cell phones’features，while cell phones added PDA-like(and even computer-like)features．The result was that the smartphone came into being．
Here are some features of smartphones．
Operating system． 2. In general，a smartphone will be based on an operating system that allows it to run applications．For example，Apple’s iPhone runs the iOS，and BlackBerry smartphones run the BlackBerry OS．
Mobile Internet． 3. For this we should say thanks to the growth of 4G data networks，as well as the addition of Wi-Fi．
4. A smartphone may allow you to download apps，edit photos，and get driving directions with GPS．The applications may also allow you to create and edit Microsoft Office documents—or at least view the files．
QWERTY Keyboard．A smartphone includes a QWERTY keyboard．This means that the keys are laid out in the same manner they would be on your computer keyboard，where you don’t have to tap the number 1 to enter an A，B or C．
These are just some of the features that make a smartphone smart．5. What makes a smartphone today may change by next week，next month or next year．Well，a smartphone of the future may be in your brain．
A．Apps．
B．Documents．
C．In the beginning，there were cell phones and PDAs．
D．A smartphone is a mobile phone with an operating system．
E．The technology about a smartphone is always changing，though．
F．You can use your smartphone to link to the Internet at a higher speed．
G．Years ago，many people thought it must be a smartphone if it had a touch screen．
In 2007，the editors of the Oxford Junior English Dictionary，convinced that their reference work“needed to reflect the consensus experience of modern-day childhood．”banned a group of old terms used less today describing the natural world．They inserted newer and supposedly more useful words describing the digital fields that young people in habit today．
Thus they say goodbye to“acorn”，but say hello to“attachment”．“Beech”and“bluebell”come out of the dictionary．while“blog”and“broadband”come into it．And they say farewell to“catkin”and“cowslip”because here come“celebrity”and“chat room”．
It’s possible，of course，that those Oxford editors had a good reason for their vocabular cleansing．Perhaps they had read the Cambridge University study revealing that most young children can identify Pokémon(神奇宝贝)species far more easily than they can name real-life sparrows．
But is this simply another fight in the language war，an ongoing battle between people? Some people argue that a dictionary should model how language works best，while some people insist that it should capture how language works now．
In Britain，some citizens felt justified in fighting back against the decision of the Oxford editors．The protest of the thinning of the word herd almost immediately attracted more than200，000 signatures．
Susie Dent，author of Modern Tribes：The Secret Languages of Britain，is doing everything in her power to guarantee“the old markers of time”．“Fortnight”(fourteen nights，or two weeks)is among her cherished favorites．
Thanks to them，I can now show off my knowledge that a“snollygoster”is a“shrewd person，especially a politician”．

A huge lake of salty water appears to be buried deep in Mars，scientists reported this week．The presence of water raises the chances of finding life on the red planet．The discovery is based on observations by a European spacecraft．It has excited experts．Water is necessary for life，and scientists have long hoped to prove that it is present on Mars．
Cassie Stuurman is a geophysicist at the University of Texas．In 2016，she found evidence of a huge ice deposit(沉积)on Mars．“If these researchers are right，this is the first time we’ve found evidence of a large water body on Mars．”Stuurman said．Researchers are not yet sure how deep the area of water is．So，they cannot say whether it is an underground pool，or just an area of soft and wet soil．
In order to find the water，Italian researchers examined radar signals．The signals were collected over three years by the European Space Agency’s Mars Express spacecraft．The results suggest that a 20-kilometer-wide water body lies below ice that is 1.5 kilometers thick．They believe the area is close to the planet’s southern pole．
Mars is very cold，but salt in the water may have kept it from freezing．It is the same as when you put salt on a road to prevent ice from forming．The water would be extremely cold，right at the point where it’s about to freeze．And it would be salty．Such conditions are not ideal for life to form．But，she said there are bacteria on the earth that have been able to survive in similar conditions．
Mars has been a popular planet for exploration，with some groups placing instruments on its surface and others examining it from space．In May，NASA launched another spacecraft，the InSight Mars lander which will dig deep into the data under the surface after it reaches a flat area of the planet in November．

4.What is the main idea of the text?
A. Life used to exist on Mars．

I live in the center of the city and there is a large parking lot full of parking spots nearby．Rain is a rare occurrence in LA，so cars easily collect pollutants and dust．Together with my friends，I decided it should be a kind gesture to surprise the owners with a car wash．So we bought car washing supplies and brought out all the bath towels we could find．With all the supplies in hand，we were able to convince another roommate to help out as well and we began watering down the cars．
Every once in a while，someone would come by and asked us seemingly stupid men，“Who told you to wash the cars?”or，even better，“who paid you to wash their cars?”We explained we just wanted to do something kind．But our response was often me with an even more confused look．
As the afternoon went on，some other friends that came by understood our goal of the spontaneous event and started helping out with some of the duties．First one friend then two，and by the time we had cleaned the entire lot，we had an entire car washing crew with independent individually assigned tasks and duties．
I wasn't cleaning cars to be able to afford a new phone．I was cleaning cars simply because I wanted to offer the car owners kindness．There was no equipment to weigh our value created．We couldn’t measure our success in dollars earned over the time spent washing cars when we could have been earning twice as much at work．
I now realize，first hand，that there is a special energy created when you choose to think bigger than yourself and act in service of others and maybe，like me，you’11 find it’s actually the greatest gift you’ you’ll ever get．
