As she ran her eyes over the flight-test calculation sheets the engineer had given her, Katherine Goble could see there was something wrong with them. The engineer had made an error with a square root (平方根). And it was going to be tricky to tell him so. It was her first day on this assignment, when she and another girl had been picked out of the computing pool at the Langley aeronautical laboratory, to help the all-male flight research unit.

But there were other, more significant snags (障碍) than simply being new—he was a man and she was a woman. In 1953 women did not question men. They stayed in their place, in this case usually the computing pool, tapping away on their desktop calculators or filling sheets with figures, she as neatly turned out as all the rest. Men were the grand designers, the engineers; the women were “computers in skirts”, who were handed a set of equations (方程式) and exhaustively, diligently checked them. Men were not interested in things as small as that.

Nonetheless, this engineer’s calculation was wrong. If she did not ask the question, an aircraft might not fly, or might fly and crash.

So, very carefully, she asked it. Was it possible that he could have made a mistake? He did not admit it but, by turning the colour of a cough drop, he ceded (屈服) the point. She asked more such questions, and they got her noticed. As the weeks passed, the men “forgot” to return her to the pool. Her incessant “why?” and “how?” made their work sharper. It also challenged them. Why were their calculations of aerodynamic forces so often out? Because they were maths graduates who had forgotten their geometry, whereas she had not; her high-school brilliance at maths had led to special classes on analytic geometry in which she, at 13, had been the only pupil.

Why was she not allowed to get her name on a flight-trajectory report when she had done most of the work? Because women didn’t. That was no answer, so she got her name on the report, the first woman to be so credited. Why was she not allowed into the engineers’ lectures on orbital mechanics and rocket propulsion? Because “the girls don’t go”. Why? Did she not read Aviation Week, like them? She soon became the first woman there.

As NASA’s focus turned from supersonic flight to flights in space, she was therefore deeply involved, though still behind the scenes. She ensured that Alan Shepards mercury capsule splashed down where it could be found quickly in 1961, and that John Glenn in 1962 could return safely from his first orbits of the earth. Indeed, until she had checked the figures by hand against those of the newfangled electronic computer, he refused to go.

Later she calculated the timings for the first moon landing (with the astronauts’ return), and worked on the space shuttle. But in the galaxy of space-programme heroes, despite her 33 years in the flight research unit, for a long time she featured nowhere.

It did not trouble her. First, she also had other things to do: Raise her three daughters, cook, sew their clothes, care for her sick first husband. Second, she knew in her own mind how good she was—as good as anybody. She could hardly be unaware of it, when she had graduated from high school at 14 and college at 18, expert at all the maths anyone knew how to teach her.

But when their story emerged in the 21st century, most notably in a book and a film called “hidden figure”, she had a NASA building named after her and a shower of honorary doctorates.

Do your best, she always said Love what you do. Be constantly curious. And learn that it is not dumb to ask a question; it is dumb not to ask it. Not least, because it might lead to the small but significant victory of making a self-proclaimed (自称的) superior realise he can make a mistake.

    Eliud Kipchoge’s extraordinary sub-two-hour marathon in Vienna on Saturday is one of the greatest sporting achievements—recording a time that has never been achieved before, again. It is a time on the fringes (边缘) of what scientists believe is humanly possible.

“It is a great feeling to make history in sport after Sir Roger Bannister in 1954. I am the happiest man in the world to be the first human to run under two hours and I can tell people that no human is limited,” Kipchoge said afterwards.

Is he right? Where are the limits of human ability? And how close are we to reaching them?

Raph Brandon, head of science for England cricket, distinguishes between achievements which are constrained (限制) by human anatomy (解剖学), and those which require human determination or skill.

“When Bolt ran 9.58 in Berlin 10 years ago, if you analyse the split times it’s very hard to imagine where the improvement comes from,” said Brandon, “The Usain Bolt 100m or the two-hour marathon, they’re in that category.”

Multi-day, ultra-endurance events, such as Thomas’s cross-Channel swim, are different, Brandon said.

“They need determination, psychology and bloody-mindedness to go that little bit further. Those people will continue to do unique things because you’re not really taking the body to its anatomical limit. It’s more a question of how much you’re prepared to consume and exhaust yourself.”

And there’s a third category, those sporting endeavours (努力) that rely on hand-eye coordination: the goal tallies of Cristiano Ronaldo and Lionel Messi, and the batting of Virat Kohli Steve Smith or Don Bradman, who trained by hitting a golf ball with a stump against a wall to become the best batsman ever to play Test cricket.

Equipment has been a factor for many sports. NFL receivers wear gloves that enable them to make improbable one-handed catches. The GB cycling team swept the board at the Olympics because of their amazing new clothing tech.

The line between what is fair and unfair is blurry. Kipchoge’s sub-two-hour run will not be officially recognized. He ran behind a car which beamed a green laser on to the ground in front of him. Teams of pacemakers, 41 in total, ran in a v-formation to protect him from headwinds (逆风). He wore specially designed shoes and the time and date of the event were picked only after detailed weather forecasting.

Jo Davies, a sport psychologist, says recent studies have shown athletes can push themselves harder because of their perception of exhaustion.

Other research published this year which looked at athletes who had won multiple gold medals found that they were different in several important ways. They had often had a shocking and upsetting life experience and had suffered significant setbacks in their performance during their careers, as well as personality traits of determination, perseverance and perfectionism.

So whether or not those limits have been reached, there will be no shortage of people prepared to try to go beyond them.

1.Why is Eliud Kipchoge’s sub-two-hour marathon considered extraordinary?

A.It was made in Vienna on a weekend.

B.It pushed the limits of human ability.

C.It proved that there was no boundary of his achievements.

D.It was greater than the record kept by Sir Roger Bannister.

2.The Usain Bolt 100m and the two-hour marathon belong to the same category in that ________.

A.they need great determination or skills B.they can be achieved via equipment

C.they rely on hand-eye coordination D.they are reaching anatomical limit

3.Kipchoge’s sub-two-hour marathon will not be officially recognized because ________.

A.he was followed by pacemakers B.he was caught in headwinds

C.he got much special help D.he didn’t run on the picked day

4.It can be inferred from the last three paragraphs that ________.

A.Jo Davies believes that athletes make progress in the same way

B.anatomical limit prevents athletes from having sad life experience

C.an athlete who has suffered setbacks will win gold medals

D.whether an athlete can succeed or not may depend on himself

    You’ve got the butter, the eggs, the organic salad greens and the laundry soap. And so you make your way to the front of the grocery store, which is where you’ll face your moment of truth:

Will you step in behind the mom with a wiggly baby and a full cart? Or take your chances with the young couple you spotted arguing over the best milk in Aisle 3B?

Better make up your mind, quick. Because, faster than the guy with “just one item” who’s about to cut in line, this whole scene is going to disappear.

Amazon recently opened its own convenience store, Amazon Go, in Seattle. It’s the first of its kind: a truly cashless grocery experience in which shoppers enter through gates that look like subway turnstiles (闸机), take what they want from the shelves and exit the way they came. No carts, no lines, no waiting. The store accurately lists what you take and charges your Amazon account, efficiently delivering an electronic receipt after you’ve left. Like most things that Amazon does, this smells like inevitability. We know, as surely as we knew the day that first Amazon box showed up on the doorstep, that the future of shopping has arrived.

Like all progress, it comes at a cost. “Based on data”, says Manoj Thomas, a professor of marketing at Cornell University, “we know that when people use any abstract form of payment, they spend more. And the type of products they choose changes too.”

Decades of psychological research has reinforced the knowledge that the further we are removed from “the pain of paying,” the less we understand how much were really spending. “If you are paying by credit card,” says Thomas, “you might pause at the checkout and suddenly think,” Should I be buying this? “Or if you are paying cash, that reflection happens at the very beginning. Both will be gone with the Amazon store.” Unhealthy impulse purchases and overspending will result from it, he says. “Both are completely related because they are influenced by our impulse urges.”

Win Is Thomas advocating that we all make a run for the atm and attempt to turn back time by using old hard currency? “No, no, no,” he says.

He envisions a world in which you’ll be able to set budget or calorie limits on an app that will recognize when you pick up unhealthy or budget-busting items and will warn you that they fall outside your goals. He expresses confidence that there is some tech hero out there right now, figuring out this exact solution to keep us all on the straight and narrow.

1.What does the underlined phrase “this whole scene” in Paragraph 2 refer to?

A.Customers arguing over the best item. B.Customers lining up at the checkout.

C.Customers cutting in line for the bargains. D.Customers doing shopping with their babies.

2.What might you experience if you do shopping in Amazon Go?

A.Less “pain of paying” at the checkout counter.

B.Convenient entering through subway turnstiles.

C.Overspending on more than you actually need.

D.Quicker delivering of goods to your car.

3.Manoj Thomas probably holds the view that ________.

A.abstract payment contributes to market prosperity

B.impulse consumption may be regulated with the new app

C.extra spending will surely not happen with the warning of the app

D.it is better for people to use cash or credit cards to avoid overspending
