It's a little hard to figure out the rules for sure but the baby African buffalo (水牛）seems to have the upper hand. The two stand a couple　 feet apart, staring at each other. Behind them, their mothers look on with the kind of indifference (不关心）of mothers everywhere who see their kids playing a harmless game.

The alarm went off about half an hour ago, the second time tonight. Here，one bell means "elephant ",two "rhino"(犀牛），and three and four，I really can't remember for what，because when you' re awoken by bells in the middle of the night，your first thought won’t be Animal", But as soon as I realized it was the rhino alarm, I was running for the stairs.

Yet I'm the only one watching the animals stare-down. Either nobody else died of a heart attack when the bells went off, or I was the only one in the entire hotel who didn't turn the alarm switch to off before going to bed.

The Ark, a hotel shaped like the biblical ark(圣经的方舟), lies in the highlands of Kenya’s Aberdare National Park, about 100 kilometers north of Nairobi. At the Ark's prow (船首) are huge windows overlooking a waterhole. Earlier tonight，I'd watched a pack of wolves, buffalos and elephants. And now, at Three or so in the mornings　 I'm　 down　 for　 the round of rhino bells. The first time, 2.5 hours ago, it was a single black rhino, which came　 down, got a　 drink, and left.

I'd have been sorry for the lost sleep. I've already arranged with a guide to take me out at sunrise for the so-called "should-never-missed" bird-watching, where well get to see 30 species, but really, how many times in your life will you get to wake up and say，"Wow! Rhino? Isn't that the definition of a pretty good right? Last week we went from Uganda into Kenya，Before I left home, I thought I'd be happy with ten elephants and five or six giraffes on the whole trip.I　 didn't dare to dream the rhino.

1.The message that the hotel's bells sent was 　　　　 .

A. a very wise way the author had never heard of

B. hard for the author to remember in detail

C. a matter that all visitors had got used to

D. like conditioned response training for animals

Ronald Reagan ever said, “It’s true hard work never killed anybody, but I figure, why take the chance?” To some extent, extra effort seems to be self-defeating. Studies suggest that, after 50 hours a week, employee productivity falls sharply.

But that doesn’t stop some managers from demanding that workers stay chained to their desk for long periods. Jack Ma, the founder of Alibaba, recently praised the “996” model, where employees work from 9 a.m. to 9 p.m., 6 days a week, as a “huge blessing”. Apparently, presenteeism (出勤主义) is the curse of the modern office worker.

There will be days when you do not have much to do: perhaps because you are waiting for someone else in a different department, or a different company, to respond to a request. As the clock ticks past 5 pm, there may be no purpose in staying at your desk. But you can see your boss hard at work and, more importantly, they can see you. So you make an effort to look busy.

Some of this may be a self-continuing cycle. If bosses do not like to go home before their employees, and employees fear leaving before their bosses, everyone is trapped. Staff may feel that they will not get a pay rise, or a promotion, if they are not seen to be putting in maximum effort. This is easily confused with long hours. Managers, who are often no good at judging employees’ performance, use time in the office as a measure. The consequence is often wasted effort. We pretend to work and managers pretend to believe us. Rather than work hard, you try to make bosses think that you are. Leaving a jacket on your office chair, walking around purposefully with a notebook and sending out emails at odd hours are three of the best-known tricks. After a while this can result in collective self-delusion that this pretence is actual work.

But presenteeism has more serious consequences. It is perhaps most common in Japan, where people attend the office even when they are in discomfort. In doing so, they are doing neither themselves nor their employers any favours. As well as reducing productivity, this can increase medical expenses for the employer. According to a study in the Journal of Occupation and Environmental Medicine, these costs can be six times higher for employers than the costs of absenteeism among workers. Those workers were more likely to experience greater pain and to suffer from depression.

In the evolution of humanity, presenteeism is a recent phenomenon. In the industrial era, workers were paid not for their output but for their time, and were required to clock in and out. But modern machinery like smartphones and laptops is portable. Turning an office into a prison, with prisoners allowed home for the evenings, does nothing for the creativity that is increasingly demanded of office workers as routine tasks are automated. To be productive you need presence of mind, not being present in the flesh.

1.What can we learn from Paragraph 2 and Paragraph 3?

A. Employees often have to work extra hours.

B. Extra effort improves employees’ productivity.

C. “996” model is well received around the world.

D. Both bosses and employees are devoted to their jobs.

2.What does the underlined “This” in Paragraph 4 refer to?

A. Hoping to get a pay rise. B. Going home after the boss.

C. Putting in maximum effort. D. Judging employees’ performance.

3.Which of the following is one the results of long-time presenteeism?

A. Reducing medical costs of employees.

B. Making employees more hard-working.

C. Increasing the competition among employees.

D. Worsening employees’ physical and mental condition.

4.What does the author want to tell us in the last paragraph?

A. Employees should be treated as prisoners.

B. Productivity can’t be measured by presenteeism now.

C. Office tasks usually can’t be carried out automatically.

D. Office workers should be allowed to be absent-minded.

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.

When you were trying to figure out what to buy for the environmentalist on your holiday list, fur probably didn’t cross your mind. But some ecologists and fashion (时装)enthusiasts are trying to bring back the market for fur made from nutria(海狸鼠).

Unusual fashion shows in New Orleans and Brooklyn have(showcased)nutria fur made into clothes in different styles. “It sounds crazy to talk about guilt-free fur-unless you understand that the nutria are destroying vast wetlands every year”, says Cree McCree, project director of Righteous Fur.

Scientists in Louisiana were so concerned that they decided to pay hunters $5 a tail. Some of the fur ends up in the fashion shows like the one in Brooklyn last month.

Nutria were brought there from Argentina by fur farmers and let go into the wild. “The ecosystem down there can’t handle this non-native species(物种).It’s destroying the environment. It’s them or us.” says Michael Massimi, an expert in this field.

The fur trade kept nutria check for decades，but when the market for nutria collapsed in the late 1980s，the cat-sized animals multiplied like crazy.

Biologist Edmond Mouton runs the nutria control program for Louisiana. He says it’s not easy to convince people that nutria fur is green, but he has no doubt about it. Hunters bring in more than 300,000 nutria tails a year, so part of Mouton’s job these days is trying to promote fur.

Then there’s Righteous Fur and its unusual fashion. Model Paige Morgan says，”To give people a guilt-free option that they can wear without someone throwing paint on them-1 think that’s going to be a massive thing, at least here in New York.” Designer Jennifer Anderson admits it took her a while to come around to the opinion that using nutria fur for her creations is morally acceptable. She trying to come up with a lable to attach to nutria fashions to show it is eco-friendly.

1.What is the purpose of the fashion shows in New Orleans and Brooklyn?

A.To promote guilt-free fur.

B.To expand the fashion market.

C.To introduce a new brand.

D.To celebrate a winter holiday.

2.Why are scientists concerned about nutria?

A.Nutria damage the ecosystem seriously.

B.Nutria are an endangered species.

C.Nutria hurt local cat-sized animals.

D.Nutria are illegally hunted.

3.What does the underlined word “collapsed” in paragraph 5 probably mean?

A.Boomed. B.Became mature. C.Remained stable. D.Crashed.

4.What can we infer abouf wearing fur in New York according to Morgan?

A.It’s formal. B.It’s risky. C.It’s harmful. D.It’s traditional.
