當(dāng)前位置：試題詳情

Recently，many e-commerce（platforms，including Didi Taxi，Ctrip，F(xiàn)liggy，JD and Taobao，have been uncovered that they are cheating their frequent customers.Their ways are pretty clever.When there are new users or conservative old users，they will give a quite appealing price to attract them into registering and buying goods.However，their big data is not friendly to the stable users and frequent visitors.The system always offers them higher price for the same products or service.How does this happen？According to the data analysis，the system knows clearly that although they feel the price is high，they will finally pay the bill.By collecting and analyzing users' profiles，buying habits and other information，big data recommends the same products to different users with different prices.
Companies also try other ways to make money，making online consumption（消費） far more worrying.For example，video websites always offer 120 seconds' advertisements，which drives people crazy.And even if you pay for the membership to get rid of the ads，you have to "enjoy" 15-second "private" ads.By broadcasting them，companies make huge profits-second to the membership fees.Also，owning 100 Mbps network，you still put up with the slow speed when you are downloading a song.You have no choice but to become a VIP when you seek high quality services.Users seem to be lambs（羊羔） among wolves.Even though they say， "Since you have money，I'll charge you more"，we can't do anything about it.
It pains us that we haven't figured out a way to deal with the problem.The only thing we can do is replacing our iPhones with Android phones if we want to buy a membership card，and applying for new accounts if we want cheaper hotels.Not finding a way to fight back，we can't do anything but accept them passively.

1．Someday a stranger will read your e-mail without your permission or scan the Website you've visited，or perhaps someone will casually glance through your credit card purchases or cell phone bills to find out your shopping preferences or calling habits．
In fact，it's likely some of these things have already happened to you．Who would watch you without your permisson？It might be a spouse，a girlfriend，a marketing company，a boss，a cop or a criminal．Whoever it is，？they will see you in a way you never intended to be seen-the 21st century equivalent of being caught naked．
Psychologists tell us boundaries are healthy，and that it's important to reveal yourself to friends，family and lovers in stages，at appropriate times．But few boundaries remain．The digital bread crumbs （碎屑） you leave everywhere make it easy for strangers to reconstruct who you are，where you are and what you like．In some cases，a simple Google search can reveal what you think．Like it or not，increasingly we live in a world where you simply cannot keep a secret．
The key question is：Does that matter？
For many Americans，the answer apparently is"No．
When opinion polls ask Americans about privacy，most say they are concerned about losing it．A survery found an overwhelming pessimism about privacy，with 60 percent of respondents saying they feel their privacy is"slipping away，and that bothers me．"
But people say one thing and do another．Only a tiny fraction of Americans change any behaviors in an effort to preserve their privacy．Few people turn down a discount at tollbooths（收費站） to avoid using the EZ-Pass system that can track automobile movements．And few turn down supermarket loyalty cards．Privacy economist A lessandro Acauisti has run a series of tests that reveal people will surrender personal information like Social Security numbers just to get their hands on a pitiful 50-cents-off coupon （優(yōu)惠券）．
But privacy does matter-at least sometimes．It's like health：When you have it，you don't notice it．Only when it's gone do you wish you'd done more to protect it．

A．There is always something you shouldn't reveal．

D．There should be fewer disputes and questions between friends．
（3）Why does the author say"we live in a world where you simply cannot keep a secret"？

A．Modern society has finally evolved into an open society．
B．Many search engines profit by revealing people's identities．
C．There are always people who are curious about others'affairs．

3．Fear is an emotion（情感） like others such as happiness，anger，hurt and sadness.We need emotions to process information we receive and decide how to respond.Being afraid of fast cars，for example，is something that might protect us from harm.Being afraid of the consequence of a choice may prevent us getting into trouble.
   Fears in young children commonly center on certain animals like snakes or big dogs.Fears are caused often because of experiences or ideas expressed by others，and at times，the media.Many normal fears during the early years，like men with beards，or large dogs，disappear with age.Those fears relating to personal failure and ridicule （嘲笑） last through adulthood and may need special help to overcome.
   Children's fears are often trivial，but that doesn't mean we should pay no attention to them.They need to be recognized and accepted as real for that child.Only when we help children understand their fears can they grow normally in their ability to deal with them.
   Research shows that as a child grows up，the center of his fears changes a lot.Things like divorce，a teacher who "shouted at me"，people with guns，bullies，big boys，or "making fun of me" top the list of childhood fears.
   We cannot always prevent these experiences from happening，but it's essential that children be allowed to freely express their emotions without judgment.Sympathy and a caring listener will help ease the pain of these fears.Read books and stories to your child about children who have experienced similar fears.This helps children talk about their fears and find ways to handle.With all emotions，fears become less of a problem for children as they gain self-confidence and they find that fear is common and can be dealt with.

.
A．only center on frightening animals
