How Much to Tip
You’re out to dinner . The food is delicious and the service is fine . You decide to leave a big fat tip . Why ? The answer may not be as simple as you think .Tipping , psychologists have found , is not just about service . Instead , studies have shown that tipping can be affected by psychological reactions to a series of different factors from the waiter’s choice of words , to how they carry themselves while taking orders , to the bill’s total . Even how much waiters remind customers of themselves can determine how much change they pocket by the end of the night .“Studies before have shown that mimicry brings into positive feelings for the mimicker ,”wrote Rick van Baaren , a social psychology professor . “ There studies show that people who are being mimicked become more generous toward the person who mimics thorn .”
So Rick van Baaren divided 59 waiters into two groups . He requested that half serve with a phrase such as “ Coming up ! ” Those in the other half were instructed to repeat to orders and preferences back to the customers . Rick van Baaren then compared their take home . The results were clear-it plays to mimic your customers . The copycat waiters earned almost double the amount of tips to the other group .
Leonard Green and Joe Myerson , psychologists at Washington University in St . Louis found the generosity of a tipper may be limited by his bill . After research on the 1,000 tips left for waiters , cab drivers , hair stylists , they found tip percentages in these three areas dropped as customers’bills went up . In fact , tip percentages appear to plateau when bills topped $100 and a bill for $200 made the worker gain no bigger percentage tip than a hill for $100 .
“That’s also a point of tipping ,” Green says . “ You have to give a little extra to the cab driver for being there to pack you up and something to the waiter for being there to serve you . If they weren’t there you’d never get any service . So part of the idea of a tip is for just being there .”

How Much to Tip
You’re out to dinner. The food is delicious and the service is fine. You decide to leave a big fat tip. Why? The answer may not be as simple as you think.
Tipping, psychologists have found, is not just about service. Instead, studies have shown that tipping can be affected by psychological reactions to a series of different factors from the waiter’s choice of words, to how they carry themselves while taking orders, to the bill’s total. Even how much waiters remind customers of themselves can determine how much change they pocket by the end of the night.
“Studies before have shown that mimicry (模仿) brings into positive feelings for the mimicker,” wrote Rick van Baaren, a social psychology professor. “These studies show that people who are being mimicked become more generous toward the person who mimics them.”
So Rick van Baaren divided 59 waiters into two groups. He requested that half serve with a phrase such as, “Coming up!” Those in the other half were instructed to repeat the orders and preferences back to the customers. Rick van Baaren then compared their take-home. The results were clear — it pays to mimic your customer. The copycat(模仿者) waiters earned almost double the amount of tips to the other group.
Leonard Green and Joel Myerson, psychologists at Washington University in St. Louis, found the generosity of a tipper may be limited by his bill. After research on the 1,000 tips left for waiters, cabdrivers, hair stylists, they found tip percentages in these three areas dropped as customers’ bills went up. In fact, tip percentages appear to plateau (达到稳定水平) when bills topped $100 and a bill for $200 made the worker gain no bigger percentage tip than a bill for $100.
“That’s also a point of tipping,” Green says. “You have to give a little extra to the cab driver for being there to pick you up and something to the waiter for being there to serve you. If they weren’t there, you’d never get any service. So part of the idea of a tip is for just being there.”
1. Apart from service, how many other factors affecting the customers’ tipping are mentioned in the passage?
A. 1. B. 2. C. 3. D. 4.
2. These studies show that _________.
A. tipping can be affected by physical reactions to many different waiter’s factors
B. people who are being mimicked usually tip less to the person who mimics them
C. the mimic waiters can get almost twice as much money as the other group
D. mimicry makes the mimicker feel bad
3. According to the passage, which of the following will be likely to show the right change of the tip percentages?
A B C D
4. We know from the passage that the writer seems to __________.
A. object to Mr. Green’s idea about tipping

C. give his generous tip to waiters very often

One step too far
Scientists have been trying to figure out how to alter the genes of humans for many years now, and it looks like they've finally cracked (破解) the code. But while this may seem like a great step forward in science, some also believe that it's one step back when it comes to ethics.
In August, a group of scientists from the US and South Korea worked together to successfully edit a human embryo and remove a genetic mutation (突变) that would have led to heart disease, reported The Guardian.
This was achieved with the help of CRISPR, a gene-editing tool that allows scientists to “cut and paste” human DNA.
Although this was the first example of an embryo's genes being changed successfully, the benefits of gene editing have already been tested in living patients.
In 2015, a five-month-old girl from the UK was saved after doctors used edited cells to fight off her cancer. As of today, she's alive and well.
And in the US last year, scientists managed to remove HIV cells from several patients by editing the genes inside their bodies.
Some people hope that in the future, diseases or birth detects could simply be “edited out”. However, others believe this could lead to so-called designer babies, giving parents the option to choose everything from eye color to intelligence.
“You could find wealthy parents buying the latest ‘upgrades’ for their children, leading to even greater inequality than we already live with,” Marcy Darnovsky, director of the San Francisco Center for Genetics, told BBC News.
In spite of these ethical concerns, experts say it’s not possible to create the “perfect” human being. Despite the progress scientists have made, we don’t understand human genes enough to give all unborn child great brainpower or amazing singing abilities.
“Right now, we know nothing about genetic enhancement,” Hank Greely, a director of sciences at Stanford University, US, told The New York Times. “We’re never going to be able to say, honestly, ‘This embryo looks like it would score high on the two-part SAT.’”
So it looks like if we want good exam results, or to impress people with our piano skills, we’ll have to stick with the old fashioned method of plain hard work — at least for now.
1.The underlined word “alter” in Paragraph 1 probably means ______.
A.record
B.change
C.remove
D.increase
2.Why do some people consider human gene editing a step backwards? ______
A.They don't think it is an effective way to light diseases.
B.They are concerned that it could lead to genetic mutations.
C.They think it could lead to designer babies and increased inequality.
D.They worry that it could make parents abandon children with birth defects.
3.What was the first successful example of human embryo gene editing? ______
A.A genetic mutation related to heart disease was removed by scientists
B.A newborn baby with cancer was saved by edited cells.
C.HIV cells were removed from patients’ bodies.
D.Some birth defects were simply edited out.
4.What can we conclude from the text? ______
A.Gene editing is regarded as the perfect way to treat birth defects.
B.There is still a long way to go to fully understand human genes.
C.Gene editing could help enhance human intelligence in the near future.
D.Scientists are pessimistic about the future of gene editing.
