一．閱讀理解（共4小題）

• 1．You can choose a private setting when you browse（瀏覽）the Internet．But be forewarned：It may not afford nearly as much privacy as you expect．That's the finding of a new study．
     Major web browsers，such as Google's Chrome and Apple's Safari，are often a private-browsing option．It's sometimes referred to as "being incognito"．This option lets you surf the Internet browser and saves a record into its history of each page that you visited．And what sites you visit won't affect the suggestions your browser makes the next time you're filling out an online form．
     Many people believe incorrectly that the incognito setting broadly protects them．Most believe it even after reading a web browser's explanation of the incognito mode．
     For instance，a new study had 460 people read web browsers' descriptions of private browsing．Each person read one of 13 descriptions．Then the participants answered questions about how private they thought their browsing would be while using this tool．The volunteers didn't understand the incognito mode．This was true no matter which browser's explanation they had read．The researchers reported their findings on April 26 at the 2018 World Wide Web Conference in Lyon，F(xiàn)rance．
     More than half of the volunteers thought that if they logged in a Google account through a private window，Google wouldn't keep a record of their search history．Not true．And about one in every four participants thought private browsing hid their device's IP address．That's wrong，too．
     Blase Ur was one of the study's authors．He's an expert in computer security and privacy at the University of Chicago in Illinois． "Companies could clear up this confusion by giving better explanations of the incognito mode，" his team said．For example，the browsers should avoid vagueness（模糊）．The web browser Opera，for instance，promised users that "your secrets are safe"．Firefox encourages users to "browse like no one's watching"．In fact，someone might be． （If you'd like to know more about the research information，please click here．）

• 2．One day，12-year-old Sean Redden logged on to the Internet and went to a popular chat room．Just as he was about to sign off，he saw the name of someone he'd never seen there before，Susan．Her brief message was "Would someone help me？"
     Sean typed back， "What's wrong？" A moment later he received this message，"I can't breathe．Help me!I can't feel my left side．I can't get out of my chair．"
     Oh，man，Sean thought．Pretending to be paralyzed（癱瘓） was a bad joke．Then he wondered what if she really was sick？ "Hey，Mom，" he called． "There's a kid here who's sick or something．" Sharon looked at the computer screen． "It's not just some game，is it？" she asked．
     The message was not a joke． "Susan" was actually a 20-year-old student，working late at night at a college library near Helsinki，F(xiàn)inland-almost 7，000 miles away from Sean's home in Texas．While searching the Internet，she began to feel terrible pain all through her body．The library was silent and empty．The nearest phone was outside in the hallway．She couldn't move that far．Any movement caused the pain to get worse．Then she realized she might get help on the Internet．
     "I don't think it's a joke，Mom，" Sean said．And he typed， "Where are you？" After a long pause（暫停），the letters appeared："Finland．" Sean and Sharon couldn't believe it．Not knowing what else to do，Sharon called the local police．
     Sharon explained the situation to Officer Amy Schmidt．Schmidt told Sharon to try to get the sick girl's phone number．Texas police called the international telephone operator and asked to be connected to the proper agency（機(jī)構(gòu)）in Finland．The call was connected to a nearby rescue station．The Texas police gave Susan's address to the Finnish operator．When Sean heard that，he typed，"Help is on the way．"
     In a few minutes，Susan heard people running down the hallway outside the door．Suddenly，the door opened．Emergency workers and three policemen ran in．Susan turned once more to the computer， "They are here．Thanks．Bye bye．"
     Four days later，the police in Texas received a message from officers in Finland："Thanks to her Internet friend，Susan had received medical treatment she badly needed and is doing well．"

三．信息匹配（共1小題）

• 6．The Internet has opened up a whole new online world for us to meet，chat and go where we've never been before．
     But just as in face to face communication，there are some rules of behavior that should be followed when online．（1）

  Imagine how you'd feel if you were in the other person's shoes．
     For anything you're about to send：ask yourself， "Would I say this to the person's face？" if the answer is no，rewrite and reread．（2）

  
     If someone in the chat room is rude to you，your instinct（本能） is to fire back in the same manner．But try not to do so． （3）

  If it was caused by a disagreement with another member，try to fix the situation by politely discussing it．Remember to respect the beliefs and opinions of others in the chat room．
     （4）

  Offer advice when asked by newcomers，as they may not be sure what to do or how to communicate．When someone makes a mistake，whether it's a stupid question or an unnecessarily long answer，be kind about it．If it's a small mistake，you may not need to say anything．Even if you feel strongly about it，think twice before saying anything．Having good manners yourself doesn't give you license to correct everyone else． （5）

  At the same time，if you find you are wrong，be sure to correct yourself and apologize to those that you have offended．
     It is not polite to ask others personal questions such as their age，sex and marital status．Unless you know the person very well，and you are both comfortable with sharing personal information，don't ask such questions．
  
  A．It's natural that there are some people who speak rudely or make mistakes online．
  B．Repeat the process till you feel sure that you'd feel comfortable saying the words to the person's face．
  C．Everyone was new to the network once．
  D．The basic rule is simple：treat others in the same way you would want to be treated．
  E．When you send short messages to a person online，you must say something beautiful to hear．
  F．You should either ignore the person，or use your chat software to block their messages．
  G．If you do decide to tell someone about a mistake，point it out politely．
