John von Neumann was the oldest of 3 children of an banker, and his speed of learning new ideas and solving problems stood out early. At 17, his father tired to persuade him not to become a mathematician because he may lead a poor life being a mathematician, and so von Neumann agreed to study chemistry as well. In 1926, at 23, he received a degree in chemical engineering and a Ph.D. in mathematics. From then on, mathematics provided well enough for him, and he never had to turn to chemistry.
In 1930, von Neumann visited Princeton University for a year and then became a professor there. His first book was published in 1932. In 1933, the Institute for Advanced Study was formed, and he became one of the 6 full-time people in the School of Mathematics（Einstein was one of the others）
World War Ⅱ hugely changed von Neumann's areas of interest. Until 1940 he had been a great pure mathematician. During and after the war, he became one of the best mathematicians who put mathematics theories into practice. During the last part of the war he became interested in computing machines and made several fundamental contributions After the war, von Neumann continued his work with computers, and was generally very active in government service. He received many awards, was president of the American Mathematical Society and was a member of the Atomic Energy Commission. He died in 1957 of cancer.
Von Neumann made several great contributions and any one of them would have been enough to earn him a firm place in history. He will be remembered as one of the greatest minds of the 20th century.
Von Neumann really was a legend in his own time, and there are a number of stories about him. His driving ability is a part of his legend. He reported one accident this Way: "I was driving down the road. The trees on the right were passing me in an orderly fashion at 60 miles per hour.

Thanks to a young waiter, I only recently discovered that a friend of 20 years was once a yo-yo virtuoso(溜溜球大师).
“Oh， stop it!” Jackie said when I started laughing during our dinner. “I was, too. And I knew how to ‘Walk the Dog.’ ”
“Wow, really?” said our waiter, Jumario Simmons, flashing a big smile at us.
“Don’t encourage her,” I said.
“What else could you do?” he asked.
“I did ‘Round the World,’” Jackie said, now ignoring me completely. “That cradle(婴儿时期的) thing, too.”
I’d asked Jumario what he did when he wasn’t waiting on tables. The 24-year-old waiter was so smart that I knew there had to be more to his story. It turns out that he won a regional yo-yo competition last year. He also gives free lessons to kids. “It gives them something to do,” Jumario said. “Keeps them off the streets.”
One of the great things about eating out is the table talk with strangers, which reminds us that everyone has a life and a name. But the other day I heard that some restaurants are ending this talk between diners and servers. I listened to the reporter describe how their improvements are allowing customers to text orders from their tables to speed up service.
The reporter got my attention with this sentence: “Five minutes after typing ‘I’m at table 3’, a meal arrives at the table.” But there wasn’t a “please” with this order, which should have been a request, by the way. If you’ve ever waited on tables, you know that the last thing you need is yet another way for a customer to be unpleasant.
Most servers are constantly mediating(调解) between customers’ requests for substitutions and overworked cooks’ accusations of treason. Except at high-end restaurants, servers also have to hover like mothers of preschoolers so that we might consider them worthy of a large enough tip to lift their pay to minimum wage.
Texting a server from a table a few feet away is equal to moving our fingers and shouting, “Hey, you!” It was rude in 1957, and it’s rude now. You won’t ever find me texting a waiter or waitress.
What do we know from the text?

A lot of people are afraid spiders（蜘蛛）–even the small ones. But a big tarantula（鸟蛛）is much more terrifying for many. Now, scientists in Sri Lanka have discovered a huge species of tarantula that’s about the size of a person’s face.
The first part of the spider’s scientific name, Poecilotheria rajaei, comes from the Greek words for “spotted”(poikilos) and “wild beast” (therion). Its species name, rajaei, comes from a local police officer who helped the team that discovered the creature. Poecilotheria rajaei has 8-inch long legs, and unusual spots colored gray, pink, and yellow.
Although it is very big, is there a real reason to be afraid of one? Maybe. This tarantula has enough poisonous fluid（毒液）to kill mice and small birds and snakes –but its bite wouldn’t cause the death of most humans.
Poecilotheria rajaei was first seen in 2009, when a villager in Sri Lanka found the body of a male and brought it to Ranil Nanayakkara, co-founder of Sri Lanka’s Biodiversity Education and Research organization.
An examination of the awesome creature proved that it was a type of tarantula scientists hadn’t seen before. So Nanayakkara carefully looked through the Sri Lankan forests to try to find more of the spiders.
It’s still too early to know whether this species is endangered. But researchers fear that the tarantulas’ natural habitat is slowly being destroyed.
“ They prefer old trees, but due to the widespread removal of trees the number has dropped,” Nanayakkara said in an interview.
Tarantulas have eight legs and two body parts. They are different from insects, which have only six legs but three body parts. Tarantulas have hairy bodies and are usually larger than other types of spiders. Some species of tarantulas can live up to 25 years.
While Poecilotheria rajaei is very big, the largest tarantula is the Goliath bird-eater (Theraphosa blondi). Found in the rainforests of South America, its legs can be up to 10 inches long. But don’t worry if you ever see one: Its poisonous fluid isn’t really dangerous to humans.According to the text, Poecilotheria rajaei _______.

“Iris scan （虹膜扫描）, please,” the bank’s computer voice tells you. You step up and the computer reads your eye, comparing it to the stored file it has of your iris. The images had better match---otherwise, you won’t be able to get your money.
Iris scanning and other technologies, such as fingerprint and voice scanning, have appeared in many science fiction movies in the past. Today, these advanced technologies are part of the real world. They are common at work, the bank, the airport, and your local prison. The iris scan, fingerprint scan, and voice scan are all examples of biometrics(生物测定学), a fast developing area of automatic personal identification technology. Basically, biometrics uses various ways to verify a person’s identity, based on the individual’s unique characteristics, including fingerprints, signature, and so on.
Biometrics identification systems have a number of advantages over password systems. The primary advantage is that an individual has to be physically present in order to be identified. Another important advantage is that there are no passwords to remember, forget, lose, or steal.
The voice scan is the simplest and most affordable form of biometrics. It only requires a computer, a microphone, and the correct software. The software records a subject’s voice and then compares it to a stored voice sample for identification purpose.
For additional safety, fingerprint and handprint scans can also be employed. Fingerprint scans take the image of a fingerprint and compare it to a stored file of prints. Handprint scans identify the unique features of a hand.The first paragraph serves as a(n) ________.
| A．example | B．explanation |

often teach about happiness and what has become clear is this：There are some qualities always unhappy people have．Here are some of them．
Happy people know life can be hard and tend to live through hard times．They take responsibility for how they got themselves into a mess，and focus on getting themselves out of it as soon as possible．Unhappy people see themselves as victims of life and stay stuck in the“look what happened to me” attitude instead of finding a way through and out to the other side．
Most happy people believe in the good in people instead of thinking everyone is out to get them．Generally open and friendly towards people they meet，happy people foster(培养)a sense of community around themselves and meet new people with all open heart．Unhappy people are distrustful of most people they meet and don’t think strangers can be trusted．Unfortunately，this behavior slowly closes all chances of meeting new friends．
Unhappy people believe someone else’s good fortune steals from their own．They believe there’s not enough goodness to go around and always compare others’against theirs．This leads to jealousy(嫉妒)．Happy people know that others’good luck and circumstance are just signs of what they also can achieve if they try hard enough．They believe in unlimited possibilities and don’t get stuck in thinking one person’s good fortune limits their possible outcome in life．
There’s only so much space between the two ears．Unhappy people fill that space with constant worry and fear．Happy people experience fear and worry too，but make an important difference between feeling it and living with it．When fear or worry crosses a happy person’s mind，they’ll ask themselves if there’s an action they can take to prevent their fear or worry from happening and they take it．If not，they realize they’re spinning in fear and they lay it down．Paragraph 2 mainly shows that unhappy people tend to _______________．
