If women are mercilessly exploited year after year，they have only themselves to blame.Because they tremble at the thought of being seen in public in clothes that are out of fashion，they are always taken advantage of by the designers and the big stores.Clothes which have been worn only a few times have to be put aside because of the change of fashion.When you come to think of it，only a woman is capable of standing in front of a wardrobe packed full of clothes and announcing sadly that she has nothing to wear.
Changing fashions are nothing more than the intentional creation of waste.Many women spend vast sums of money each year to replace clothes that have hardly been worn.Women who can not afford to throw away clothing in this way waste hours of their time altering (改变) the dresses they have.Skirts are lengthened or shortened；necklines are lowered or raised，and so on.
No one can claim that the fashion industry contributes anything really important to society.Fashion designers are rarely concerned with vital things like warmth，comfort and durability.They are only interested in outward appearance and they take advantage of the fact that women will put up with any amount of discomfort，as long as they look right.There can hardly be a man who hasn’t at some time in his life smiled at the sight of a woman shaking in a thin dress on a winter day，or delicately picking her way through deep snow in highheeled shoes.
When comparing men and women in the matter of fashion，the conclusions to be drawn are obvious.Do the constantly changing fashions of women’s clothes，one wonder，reflect basic qualities of inconstancy and instability？Men are too clever to let themselves be cheated by fashion designers.Do their unchanging styles of dress reflect basic qualities of stability and reliability？That is for you to decide.
1．Designers and big stores always make money________.
A．by constantly changing the fashions in women’s clothing
B．by mercilessly exploiting women workers in the clothing industry
C．because they are able to predict new fashions for the coming seaon
D．because they attach great importance to the quality of women’s clothing2．To the writer，that women alter their old fashioned dresses is seen as________.
A．a waste of money
B．an expression of taste
C．a waste of time
D．an expression of creativity
3．According to the passage，which of the following statements is true?
A．The fashion industry makes an important contribution to society.
B．The constant changes in women’s clothing reflect their strength of characters.
C．Fashion designs should not be encouraged since they are only welcomed by women.
D．New fashions in clothing are created for the commercial exploitation of women.
4．By saying “the conclusions to be drawn are obvious”，the writer means that________.
A．women are better able to put up with discomfort
B．men are more reasonable in the matter of fashion
C．men are also exploited greatly by fashion designers
D．women’s inconstancy in their choice of clothing is often laughed at

Today，when a fire breaks out，you can be sure a citizen with a cellphone camera has posted it to Facebook or Twitter，or sent it to the media.But up to now，that citizen has not been able to easily send images and details of what is happening to the people who need it most：the police，firefighters and buildingsecurity people who must respond，and whose ability to help is often measured in minutes，if not seconds.
That’s about to change.A oneyearold company called Elerts has developed a system that’s designed to mobile and social technologies to speed the flow of information between citizens and emergency workers in time of danger.The system involves free mobile applications—iPhone and iPad app (应用软件) is available now—that eyewitnesses can use to report incidents and get public safety warnings.And Elerts is offering a management console (控制台)for security firms and universities to receive the reports and distribute warnings and instructions，like a map with the best evacuation route (疏散路线)． The service is the brainchild of Chris Russo，deputy fire chief in
the
coastal
town
of Hull，Mass.As
mobile communications sped up，he grew increasingly frustrated by his inability to communicate effectively with colleagues and the public，particularly with people who are at the scene and might be able to provide help.
“Remembering situations when communications failed puts__a_pit_in_my_stomach，” Mr Russo says.Last summer，he was in a search at a beach for a missing boy，who went into a bathhouse but didn’t come out.First responders feared an abduction (绑架) on the beach or shark attack.The child’s mother，who didn’t speak English well，was so sad that she couldn’t remember what color shorts he had on.Mr Russo had no photo of the child，and no ability to turn to beachgoers.
Two long hours later，the boy was spotted by a lowflying helicopter lost and alone on the beach crying—a lucky break.“If 5 percent of beachgoers had an app to receive a message and send in sightings of a lost boy，the happy ending might have come much sooner，” Mr Russo said.
5．What is the passage mainly about?
A．A system for reporting emergencies.
B．A moving story of Chris Russo.
C．A cellphone instant service.
D．An app for firm management.
6．The underlined part in Paragraph 4 can be replaced by “________”．
A．arouses my interest
B．causes a stomachache
C．makes me feel frustrated
D．leaves a hole in my stomach
7．We can infer from the passage that emergency workers________.
A．have to carry out rescue work in minutes
B．need images and detailed information badly
C．must send images and details immediately
D．have to turn to Facebook and Twitter for details
8．The author takes Chris Russo’s experience as an example to________.
A．advertise his creativity in communication
B．inform readers how Russo got the idea of the service
C．make the passage more interesting to read
D．show readers the working principle of the new system
