Using technology, of course. While special services via webcam(摄像头) and cheating detecting software have been developed now, Mettl, an online company, has developed advanced techniques for netting cheaters, which the company claims are even more reliable and easier to use. Whatever small attempt to cheat, he or she will be found out.

    Mettl has adopted a handful of technologies on its test—taking platform, creating a mini monitoring state in an exam. Here's how it works: A test-takersigns on to Mettl and selects hisher exam from the site's library of pre—loaded tests. Facial and keystroke recognition technology confirm the person that has signed in is the very person, and the system records both the test—taker(through the webcam)and the test—taker's screen throughout the test.

    Mettl's technology uses the test—taker's webcam to detect how many people are using the computer. Soon, it will track eye movement well enough to sense whether the test-taker is looking away from the screen, perhaps to Consult a smart phone or a friend in secret. Mettl also monitors the test-taker's screen and can detect when the test-taker has changed a computer or moved from the test. The system will soon be able to record sound, thus detecting whether the test-taker is talking or being talked to.

    If any irregularities are detected, the system flags the incident and reports it back to the test's administrator. This can bring any number of things, depending on the test-giver's wishes: a completeshutdown of the exam, a warning message that appears on the test-taker's screen, even human instructions from the control center.

    Mettl is hoping its technology will help it break into the country's big MOOC markets.

    In cities with rent control, the city government sets the maximum rent that a landlord (房东) can charge for an apartment. Supporters of rent control argue that it protects people who are living in apartment. Their rent cannot increase; therefore, they are not in danger of losing their homes. However, the critics say that after a long time, rent control may have negative effects. Landlords know that they cannot increase their profits. Therefore, they invest in other businesses where they can increase their profits. They do not invest in new buildings which would also be rent-controlled. As a result, new apartments are not built. Many people who need apartments cannot find any. According to the critics, the end result of rent control is a shortage of apartments in the city.

    Some experts argue that the minimum wage law can cause problems in the same way. The federal government sets the minimum that an employer must pay workers. The minimum helps people who generally look for unskilled, low-paying jobs. However, if the minimum is high, employers may hire fewer workers. They will replace workers with machinery. Therefore, other things being equal, the number of workers that employers want decreases. Thus, critics hold the opinion that an increase in the minimum wage may cause unemployment. Some poor people may find themselves without jobs instead of with jobs at the minimum wage.

    Supporters of the minimum wage say that it helps people keep their dignity. Because of the law, workers cannot sell their services for less than the minimum. Furthermore, employers cannot force workers to accept jobs at unfair wages.

    Economic theory predicts the results of economic decision, such as decisions about farm production, rent control, and the minimum wage. The predictions may be corrected only if “other things are equal”. Economists do not agree on some of the predictions. They also do not agree on the value of different decisions. Some economists support a particular decision while others criticize it. Economists do agree, however, that there are no simple answers to economic questions.

    If women are mercilessly exploited（剥削）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（衣橱）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 cannot afford to throw away clothing in this way,waste hours of their time altering（政变）the dresses they have.Skirts are lengthened or shortened;neck-line 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（耐用）.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 times 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 high-heeled 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 wonders,reflect basic qualities of inconstancy and instability （不稳定）?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（可靠）?That is for you to decide.

    Animal Farm by George Orwell

    Animal Farm is probably one of the most popular school reads in the world. George Orwell wrote it as a political allegory(讽喻)and has since then inspired the minds of not only adult revolutionaries but also the younger ones who start feeling the spark of being right and free for all of the humanity in their hearts.

Persepolis by Marjane Satrapi

    This is a wise, funny, and heartbreaking memory of Marjane Satrapi's years growing up in Iran during the Islamic Revolution, and how she dealt with life while experiencing the ruinous effects of the war with Iraq. The mistakes she felt she made opened her eyes and shaped her into becoming the influential individual she is today.

    To Kill a Mockingbird by Harper Lee

Regarded as a masterpiece of literature—-it is no wonder it won the Pulitzer Prize. The plot and characters are based on the author's observations of her family and neighbors, as well as on an event that occurred near her hometown in 1936, when she was 16 years old. The novel is famous for its warmth and humor, despite telling a story of innocent Tom Robinson being accused of raping(强暴)a white woman because he was black.
