Recently some American scientists have a useful piece of advice to people in industrialized nations. They say people should eat more of the same kind of food eaten by humans living more than 10, 000 years ago.1.
The scientists say that the human life has changed greatly. Our bodies have not been able to de
al with these changes in lifestyle and this has led to new kinds of sicknesses. These new sicknesses were not known in ancient times.So they are called “diseases of civilization”. 2.
Scientists noted that people in both the Old Stone Age and the New Stone Age enjoyed very little alcohol or tobacco, probably none.3. However, a change in food is one of the main differences between life in ancient times and that of today.
Stone Age people hunted wild animals for their meat, which had much less fat than domestic ones. They ate a lot of fresh wild vegetables and fruits. They did not have milk or any other dairy products, and they made very little use of grains.4.We eat six
times more salt than our ancestors. We eat more sugar. We eat twice as much fat but only one third as much protein and much less vitamin C.
5. But scientists say that we would be much healthier if we eat much the same way the ancient people did, cutting the amount of fatty, salty and sweet food.
A. People today probably don’t want to live like our ancestors.
B. Ancient people also got lots of physical exercise.
C. Stone Age people lived a simple life.
D. Many cancers and diseases of the blood system are examples of such diseases.
E. Modern people used to suffer from “diseases of civilization.”
F. But today, we enjoy eating a lot of these.
G. In that case, they would live much healthier.
Since 2013, Torobo, a robotic arm designed to test the limits of artificial intelligence. has had one ambition—to be admitted to the University of Tokyo. However, it has repeatedly failed. This year was no exception.
In early November Torobo took an exam to prepare for an all-important standardized test. While Torobo’s total score of 525 out of 950 was 14 points higher than in 2015，its standard score of 57.1% was slightly lower, because human students did better in the 2016 test.
Though the score，which is higher than the national average, is enough to get the robot admitted to many other famous Japanese universities, it falls short of the minimum required for the University of Tokyo.
A closer analysis of the results showed that Torobo's newly programmed ability to solve complex physics problems helped increase its year-over-year physics score from 46. 5% to 59%. The robot also dug deep into its database of information from textbooks and websites to obtain an impressive 66.3% in world history. The average 60% scores acquired in the two math sections, were not too shabby either.
But，while Torobo is able to handle knowledge-based questions and ones involving complex mathematical calculations, it has a hard time thinking independently. As a result, the robot is unable to fully understand multiple sentences and phrases to arrive at the logical conclusions required in the English language tests. This weakness was reflected in the weak oral and writing scores, which came in at 36.2% and 50.5% , respectively.
Fortunately, after four tiring years, the robot's creators have decided to free Torobo from its annual test-taking suffering, the research team will instead focus on improving the robot’s ability to pick out specific answers from massive sets of data—a skill that led to its excellent history scores. They believe the expertise(专业技术）will help Torobo succeed as an industrial robot.
1.What is the disadvantage of Torobo?
A. It has much difficulty searching for facts.
B. It doesn't own language skills.
C. It has weak independent thinking ability.
D. It couldn’t get through the exams.

Visitors to the grounds of New College at England’s Oxford University pass under an iron gate with the advice: Manners make the man. Even after an appropriate update to: Manners make the person, it’s thought-provoking(引人深思的)—especially to today’s Americans.
When we think about what makes the person—it’s more likely the degree, the job, the salary. Since when do we count manners as a measure of success?
We do know that these would make life nicer, if more tolerable. However, we forget or overlook our manners. So , it seems, does everyone else—including, unluckily, our children.
As a university president, one of my great joys is to visit our campuses and see our students, though we’re separated by different generations, interests, and, of course dressing, each student tells me something within the first few minutes that we meet: whether he or she has been taught manners. I sense this in different ways: through her words or her gestures, in the way she listens or how he refers to friends and faculty, how she greets and says goodbye, how he responds when an elderly person enters the room.
In the absence of manners, however, I make some allowances. For instance, the many ethnic(种族的)groups that students represent often have different explanations of what makes up good manners. In other cases, some students may reject what they’ve learned to break from their parents and be accepted by other students. Whether students are being different or openly opposing, a recent experience I had with them tells me that there’s some hope for reviving and good manners.
Good manners don’t just guarantee acceptance. Good manners open doors to deeper connections and more meaningful roles in our society. Good manners are gentle signals that show we care about one another and allow us to relate to another person in a thoughtful way but at a respectable distance.
1.Which of the following is seldom a mark of success to people today?
A. Handsome income. B. An academic degree.
C. High ranks in the office D. Polite behavior.
2.What does the underlined part “make some allowances” in Paragraph 4 probably mean ?
A. treat the absence of manners differently
B. reject the absence of manners
C. oppose bad manners somehow
D. partly permit being in the absence of manners
3.Which of the following is the benefit by good manners?
A. Good manners makes people thoughtful
B. Good manners help deeper connections with others
C. Good manners guarantee acceptance of ourselves
D. Good manners inspire people to care about one another
Imagine that you’re looking at your company-issued smartphone and you notice an e-mail from Linkedln: “These companies are looking for candidates like you!” You aren’t necessarily searching for a job, but you’re always open to opportunities, so out of curiosity, you click on the link. A few minutes later your boss appears at your desk. “We’ve noticed that you’re spending more time on Linkedln lately, so I wanted to talk with you about your career and whether you’re happy here,” she says. Uh-oh.
It’s an awkward scene. Attrition (损耗) has always been expensive for companies, but in many industries the cost of losing good workers is rising, owing to tight labor markets. Thus companies are making greater efforts to predict which workers are at high risk of leaving so that managers can try to stop them. Methods range from electronic monitor to well-designed analyses of employees’ social media lives.
Some of this work may be a reason to let employees to quit. In general, people leave their jobs because they don’t like their boss, don’t see opportunities for promotion or growth, or are offered a higher pay; these reasons have held steady for years.
New research conducted by CEB, a Washington-based technology company, looks not just at why workers quit but also at 
when. “We’ve learned that what really affects people is their sense of how they’re doing compared with other people in their peer group, or with where they thought they would be at a certain point in life, says Brian Kropp, who heads CEB’s HR practice. “We’ve learned to focus on moments that allow people to make these comparisons.”
Technology also provides clues about which star employees might be eyeing the exit. Companies can tell whether employees using work computers or phones are spending time on (or even just opening e-mails from) career websites, and research shows that more firms are paying attention to these things. Large companies have also begun searching for badge swipes (浏览痕迹)---- employees’ use of an ID to enter and exit the building or the parking garage---to identify patterns that suggest a worker may be interviewing for a job.
1.What can we infer about Linkedln in the text?
A. an e-mail B. a job from the Internet
C. a world-famous company D. a professional social network
2.According to the passage, how can companies prevent workers from quitting?
A. Companies can analyze workers’ social media lives.
B. Companies need to find out workers likely to quit.
C. Companies must try to reduce the cost of losing good workers.
D. Companies should be stricter with workers.
3.According to the research by CEB, which of the following might be the most probable reason for workers to quit their jobs?
A. Workers are always doing comparisons.
B. Not seeing opportunities for promotion.
C. To find a higher-paid job.
D. They don’t like their bosses.
4.What is the author’s purpose in writing the text?
A. To show a new trend in the job market.
B. To stress the role of new technologies.
C. To make a review on a phenomenon.
D. To tell us the leader’s concerns.
