12．Your smart phone can do a lot of things．It can call people．It connects to the Internet．It enables you to play fun games．But there is a dark side-it might also spread diseases．
This may be hard to believe，but scientists reached this conclusion after they tested eight random cell phones from an office in Chicago．All the tested phones showed high numbers of bacteria，with about 2，700to 4，200 units on each phone．In drinking water，the healthy limit is less than 1unit per 100ml （毫升） of water．
Although computers，keys and pens all carry bacteria，our smart phones get far dirtier．They touch a lot of things，including our hands and the inside of our pocket or purse．We take them almost everywhere：the bus，the subway and who hasn't played smart phone games while sitting on the toilet？
What's even worse is that after the phone returns from its dirty trip，it then spends most of its time cozying up to our faces．You don't think about how often you touch your phone to your face，do you？Our noses，mouths and ears are all warm and rich in grease （油脂），an environment that bacteria really like．
Compared to traditional keyboard，touch screens spread bacteria more easily to hands．An expert in Australia warned that playing with iPads and iPhones at Apple stores is a health risk．
There is one simple and reliable way you can reduce the bacteria on your phone's surface：wash your hands regularly．So how do you keep your smart phone clean？Alcohol is effective when used to kill bacteria from the back and side of your phone．

29．What might be the disadvantage of smart phones？A
A．It might be a potential risk of diseases．
B．It can be used to make immediate talks．
C．It can be connected with the Internet．
D．It can serve as a game-playing machine．
30．Which ottle of water may be safe to drink？A
A．A 350ml bottle of water checked with 3 units of bacteria．
B．A 500ml bottle of water checked with 50 units of bacteria．
C．A 650ml bottle of water checked with 10 units of bacteria．
D．A 1000ml bottle of water checked with 15 units of bacteria．
31．Which is true according to the passage？B
A．Our keys carry more bacteria than smart phones．
B．Smart phone users risk being exposed to bacteria．
C．There's no way to reduce the bacteria on smart phones．
D．Experts warned not to touch iPhones in Apple stores．
32．What can be the best title for the passage？C
A．A New Problem of Smart Phones
B．Take Care of Your Smart Phones
C．Smart Phones-A New Health Risk
D．How to Keep Smart Phones Clean．

About one year before，we got a lovely cat．named Tom．He enjoys watch my elderly neighbor in her garden．Although he won't let her to touch him，he always keeps an eye on her．
One afternoon I heard Tom calling strange．When I reached the door to check on him，his calling stops，so I headed back to the kitchen．Just as I did，her calling started again．I stepped outside to find Tom sitting next to my elderly neighbors who had fallen．She didn't have strength to get up and shout for help．Tom didn't leave her side until help arrived．With Tom，she might not have been found in time．

Rock concerts and construction sites are just a few places that frequently have noise levels that can damage hearing．Any place where you have to shout to be heard should be avoided．
◆（34）A
