Since American students have been introduced into the era of the Massive Open Online Course, the opportunity for cheating appears greater than ever. The all-knowing Google search engine is within easy reach. So how can a teacher handle such a large number of examinees so far away, let alone searching out cheaters taking tests across the Internet?
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 mass of technologies on its test-taking platform, creating a mini monitoring state in an exam. Here’s how it works: A test-taker signs on to Mettl and selects his／her 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, detecting whether the test-taker is talking or being talked to.
If any wrongdoings 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 complete shutdown 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.

An extinct mountain goat that was once common in the Pyrenees became the first animal to be brought back from extinction. Researchers used frozen DNA to produce a clone, but the newborn kid died within minutes of birth due to breathing difficulties.
The Pyrenean ibex is a type of mountain goat，which is believed to have died out completely in 2000. Before the death of the last known individual（a13-year-old female known as Celia）, biologists took cells from her skin and ears. An earlier cloning attempt to use the skin cells failed. But the latest attempt involved the creation of 439 cloned embryos. Of these cloned embryos, 57 were put into the female domestic goats, but only one goat gave birth and the newborn cloned kid died after seven minutes as a result of lung disease.
Researchers say that other cloned animals, including sheep, have been born with similar lung disease, but they say that overall the experiment was a major step forward in the effort to bring the ibex back to its mountain home. The leading researcher Jose Folch says, “the cloned kid was genetically like the ibex；in species such as the ibex，cloning is the only possibility to avoid its complete disappearance.”
The failure to produce a living clone from DNA that was frozen only a decade ago shows the difficulty researchers would face in trying to bring back species that have been extinct（灭绝的） for decades or centuries. Researchers have had the idea of bringing back the Tasmanian tiger, which went extinct in 1936. There are, however, other species that have been seriously suggested for cloning，such as the giant panda, the African bongo antelope, the Sumatran tiger and the pygmy hippo. Supporters believe cloning provides hope of keeping these endangered animals alive before they die out．
1.What do we know about the cloned ibex?
A. It died of lung disease.
B. It was the first cloned animal in the world.
C. It lived for thirteen years.
D. It was born in 2000.
2.Jose Foleh would agree that cloning ．
A. is not suitable and should be banned.
B. requires immediate attention.
C. should be carried out cautiously.
D. may help prevent animal extinction.
3.We can conclude from the passage that ．
A. cloning has developed quickly in developed countries.
B. no more animals will die out in the future.
C. cloning makes it possible to preserve endangered species.
D. cloning seldom results in physical problems for animals.
4.What’s the best title for this passage?
A、Great advancement in cloning goats.
B、Difficulties in saving extinct animals.
C、Public concerns about cloning.
D、Cloning brought back an extinct species for a while.

“People are ruder today because they are rushed and more ‘time poor’ than ever before,” says Patsy Rowe, “ Manners have fallen off the radar(雷达)．” Due to our strong attraction to electronic equipment it is a wonder that more people don’t wake up each morning and greet the singing birds with complaining about the noise．Here are some examples of rudeness．
Some people prefer to do almost everything over the Internet．To them, dealing with an actual human is like an evolutionary step backward． It feels very slow because humans don’t work at 4G speeds．When you have dinner with friends, you will often notice someone paying more attention to his mobile phone．We have programmed ourselves to think that every new message brings life-changing news, so taking calls and checking our texts are more important than talking to the people we are with．What is worse, some people even tend to send anonymous（匿名的）rude messages by email．
However, rudeness is never acceptable．Don’t assume it is OK to be rude if the person you’re in touch with won’t recognize you．If you have something awful to say, have the courage to face the person and say it, write a letter or email and sign it, or forget it．Upsetting people with unsigned messages is cruel and disgusting．
We shouldn’t blame technology for our shortcomings．Technology is here to help us, but we should not allow it to take over our lives．An important step is acknowledging our shortcomings．People spend a lot of time pointing out bad manners but it would be even more helpful if we’d publicly acknowledge good manners when we see them．
1.What can be inferred from the underlined sentence in Paragraph 1?
A． People can tell good from bad behavior．
B． Radar is able to observe human behavior．
C． People care little about their behavior．
D． Radar can be used to predict human behavior．
2.Some people are less willing to deal with humans because__________．
A． they are becoming less patient
B． they are growing too independent
C． they have to handle many important messages
D． they have to follow an evolutionary step backward．
3.The author thinks sending unsigned awful messages is ___________．
A． Ridiculous
B． disgusting
C． acceptable
D． reasonable
4.What can we learn from the last paragraph?
A． We should applaud good behavior．
B． Technology can never be blamed
C． We should keep pointing out mistakes．
D． Technology will take over lives one day．
