19．There are many expressions with the word"dog"．
（36）G They take their dogs for walks，give them good food and medical care．However，dogs without owners to care for them lead a different kind of life．The expression，lead a dog's life，describes a person who has an unhappy existence．
When we say we live in a dog-eat-dog world．（37）F A person has to work hard like a dog to be successful．Such hard work can make people dog-tired．And，the situation would be even worse if they became sick as a dog．
Still，people say every dog has its day．This means that every person enjoys a successful period during his or her life．（38）A Yet，some people say that you can never teach an old dog new tricks．They believe that older people do not like to learn new skills and will not change the way they do things．
Some people are compared to dogs in bad ways．People who are unkind or uncaring can be described as junkyard dogs living in places where people throw away things they do not want．Junkyard dogs are often used to guard this property．They bark or attack people who try to enter the property．However，sometimes a person who appears to be mean and threatening is really not so bad．（39）C
Dog expressions are also used to describe the weather．The dog days of summer are the hottest days of the year．（40）B But we do not want it to rain cats and dogs．

20．Every day，hundreds of thousands of us visit coffee shops．While we drink our coffee，we may connect our smartphone to the shop's Wi-Fi network，and keep in touch with friends via services such as Facebook．
As well as socializing，we may use the time and free access to a wireless connection to get on top of our finances．Transferring money from your account to others'accounts is nothing more than a few taps on your screen．
But what coffee drinkers do not realize is that lurking（潜伏） among their fellow coffee-lovers are bank robbers．
Unknown to you，this modern form of bank robber is silently collecting all your private data．The only sign of his thievery is perhaps a little smile as your bank log-in details appear on his screen．
You'll only realize when you later go to a cash machine to withdrawsome money，and discover that every penny in your account has been cleared out．
The common method for thieves is to use your smartphone's Wi-Fi connection．They rely on the fact that most of us are not careful about the security of networks we connect to．
For example，when you are in a coffee shop，your smartphone will present you with a list of available Wi-Fi networks that you can use to connect your phone to the Internet．Most of these networks are run by legitimate（合法的）companies，but sometimes they are actually created by a thief sitting nearby with little more than a laptop．
These networks are often given names，such as"Free Public Wi-Fi"，which deceive smartphone users into logging in．On the surface，everything seems normal，and you will be able to connect just as you are with a legitimate Wi-Fi service．
However，because you have connected to a network controlled by a thief，he can monitor （监视） everything you do，enabling him to collect passwords and log-in details about your bank account．

28．The underlined phrase"get on top of"can be replaced byA．
A．deal with B．give up C．cut off D．set up

D．All the networks available in a coffee shop are illegal．

A．Positive．B．Negative．C．Objective．D．Indifferent．
31．What's the best title of this passage？A
A．Be cautiousabout free Wi-Fi networks．
