Course(MOOC), the opportunity for cheating appears greater than ever. The all－knowing Google search is within easy reach. So how can a teacher handle such a large number of examinees and search out cheaters taking tests on the Internet?
Using technology, of course. Mettl, an online company, has developed advanced techniques for netting cheaters. It has adopted a mass of technologies on its test－taking platform, monitoring test－takers' performance in the exam. Here's how it works: A test－taker signs on to Mettl and select his/her exam from the site's library of pre－loaded tests. Facial and keystroke(击键) recognition technology confirm the person that has signed in is the very person, and the system records both the test－taker and the test－taker's screen throughout the test.
Mettl's technology uses the test－taker's webcam(摄像头) to detect(察觉) 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 smartphone 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. 28．From the first paragraph we can infer that ________． A．MOOC has replaced the traditional form of education B．teachers should be stricter in dealing with cheating C．preventing online cheating is a harder job D．Google is a software designed for cheating
29．How can Mettl help to get rid of cheating online? A．By equipping teachers with cameras.
B．By asking test－takers to sign in. C．By providing different tests at a time.
D．By recording the test－takers' behaviors.
30．The underlined word “flags” in Paragraph 4 means “________”． A．notices B．reacts to C．changes D．marks
31．We can conclude from the passage that the technology of Mettl is ________ in the MOOC era.
A．unreliable B．promising C．wasteful D．successful
D
Children whose mothers were exposed to higher levels of phthalates (酞酸盐), which are common chemicals in consumer products, such as raincoats and soaps, in late pregnancy (孕期), tend to score lower than other children on intelligence tests at the age of seven, according to a new study.
Researchers followed 328 New York women in low－income communities from pregnancy until their children were seven years old. When the children were seven, they completed an intelligence test measuring four areas of mental functioning. The mothers' levels of two of the phthalates—DnBP and DiBP—during pregnancy were associated with childhood intelligence: as
phthalate levels went up, the child's IQ tended to go down.
“With observational studies, there is always the chance that the results may be in part explained by an unmeasured factor that we haven't yet considered，” said Stephanie Engel, a professor from the University of North Carolina.
“I would characterize this study as thorough and high quality, and the results are worrying，” said Engel, who was not involved in the work. “But there needs to be more research in this area before firm conclusions can be drawn.”
“However, it is clear that there needs to be a serious discussion in the scientific and policy communities about whether the evidence is strong enough yet to make widespread policy changes, not just on the basis of this study, but also including a range of childhood health outcomes that have already been reported，” Engel said.
“Although there are no rules on phthalate exposure during pregnancy, it would be careful for expectant mothers to avoid microwaving food in plastic, avoid products that smell pleasant, and as much as possible, store food in glass instead of plastic containers，” she said.
32．According to the passage, the new study is about________． A．the interaction between a pregnant woman and her unborn baby B．how phthalates taken in by a pregnant woman affect her baby C．why children's IQ is different at the age of seven
D．the usage of common chemicals in consumer products 33．Which of the following statements is TRUE?
A．Researchers chose 328 pregnant women at random to do the research. B．Engel doesn't think phthalates have any risks.
C．There are two types of phthalates that may affect childhood intelligence. D．The researchers are very confident about their conclusions. 34．What can you learn from the last but one paragraph? A．The evidence is not strong enough to change the policy. B．The policy should be stricter.
C．A serious discussion is needed just based on this study. D．All studies about childhood health should be involved. 35．Where does this text probably come from? A．A children's book. B．A science report.
C．A nutrition guidebook. D．A chemistry magazine.
