One day, Mr. Arnold was teaching a lesson, and things were going as normally as ever. He was explaining the story of human being to his pupils. He told them that, in the beginning, men were nomads (游牧); they never stayed in the same place for very long. Instead, they would travel about, here and there, in search of food, wherever it was to be found. And when the food ran out, they would move off somewhere else.

He taught them about the invention of farming and keeping animals. This was an important discovery, because by learning to cultivate (耕作) the land, and care for animals, mankind would always have food steadily. It also meant that people could remain living in one place, and this made it easier to set about tasks that would take a long while to finish, like building towns, cities, and all that were in them. All the children were listening attracted by this story, until Lucy jumped up:

“And if that was so important and improved everything so much, why are we nomads all over again, Mr. Arnold?”

Mr. Arnold didn’t know what to say. Lucy was a very clever girl. He knew that she lived with her parents in a house, so she must know that her family were not nomads; so what did she mean?

“We have all become nomads again,” continued Lucy, “The other day, outside the city, they were cutting the forest down. A while ago a fisherman told me how they fish. It’s the same with everyone: when there’s no more forest left the foresters go elsewhere, and when the fish run out the fishermen move on. That’s what the nomads did, isn’t it?

The teacher nodded, thoughtfully. Really, Lucy was right. Mankind had turned into nomads. Instead of looking after the land in a way that we could be sure it would keep supplying our needs, we kept developing it until the land was bare. And then off we would go to the next place! The class spent the rest of the afternoon talking about what they could do to show how to be more civilized (文明的).

The next day everyone attended class wearing a green T-shirt, with a message that said “I am not a nomad!”

And, from then on, they set about showing that indeed they were not. Every time they knew they needed something, they made sure that they would get it using care and control. If they needed wood or paper, they would make sure that they got the recycled kind. They ordered their fish from fish farms, making sure that the fish they received were not too young and too small. They only used animals that were well cared for, and brought up on farms.

And so, from their little town, those children managed to give up being nomads again, just as prehistoric men had done, so many thousands of years ago.

When milk arrived on the doorstep

When I was a boy growing up in New Jersey in the 1960s, we had a milkman delivering milk to our doorstep. His name was Mr.Basille. He wore a white cap and drove a white truck. As a 5-year-old boy, I couldn’t take my eyes off the coin changer fixed to his belt. He noticed this one day during a delivery and gave me a quarter out of his coin changer.

Of course, he delivered more than milk. There was cheese, eggs and so on. If we needed to change our order, my mother would pen a note-“Please add a bottle of buttermilk next delivery”—and place it in the box along with the empty bottles. And then, the buttermilk would magically appear.

All of this was about more than convenience. There existed a close relationship between families and their milkmen. Mr. Basille even had a key to our house, for those times when it was so cold outside that we put the box indoors, so that the milk wouldn’t freeze. And I remember Mr. Basille from time to time taking a break at our kitchen table, having a cup of tea and telling stories about his delivery.

There is sadly no home milk delivery today. Big companies allowed the production of cheaper milk thus making it difficult for milkmen to compete. Besides, milk is for sale everywhere, and it may just not have been practiced to have a delivery service.

Recently, an old milk box in the countryside I saw brought back my childhood memories. I took it home and planted it on the back porch. Every so often my son’s friends will ask what it is. So I start telling stories of my boyhood, and of the milkman who brought us friendship along with his milk.

Cancer researchers urged people on Wednesday to take more vitamin D to lower risk of cancer, saying studies showed a clear link. “Our suggestion is for people to increase their intake, through diet or a vitamin supplement. ” Dr.Cedric Garland said in a telephone interview.

Garland’s research team reviewed 63 studies, including several large long-term ones, on the relationship between vitamin D and certain types of cancer worldwide between 1966 and 2004.

“There’s nothing that has this ability to prevent cancer,” he said, urging governments and public health officials to do more to fortify foods with vitamin D. Garland is part of a University of California at San Diego Moores Cancer Center team that published its findings this week online in the American Journal of Public Health. Vitamin D is found in milk, as well as in some fortified orange juice, yogurt and cheeses, usually at around 100 international units(IU) a serving. People might want to consider a vitamin supplement to raise their intake to 1000 IUs per day, Garland said, adding that it was well within the safety guidelines established by the National Academy of Sciences.

The authors said that taking more vitamin D could be especially important for people living in northern areas, which receive less vitamin D from sunshine.

African Americans, who don’t produce as much of the vitamin because of their skin colour, could also benefit significantly from a higher intake, the authors said.

1.According to the passage, people are advised to take more Vitamin D because ________.

A. it is nutritious

B. it can’t harm people’s health

C. it can lower cancer risk

D. it is not taken enough every day

2.Who can Garland probably be?

A. A health researcher.

B. A doctor.

C. A scientist.

D. A public health official.

3.Which of the following food can lower people’s chance of getting cancer?

A. Milk.

B. Fortified orange juice.

C. Fortified yogurt.

D. All of the above.

4.People from which area should take more Vitamin D according to the passage?

A. Asian people.B. African people.

C. American people.D. European people.

“One thing I enjoy about my job is that I can work on something that is actually active,” says Game McGimsey, an American volcanologist(火山学家). Part of his job includes keeping an eye on Alaska’s many active volcanoes and giving people a heads-up when a volcano might erupt(喷发).

Like most jobs in the science, volcanology requires a lot of education. McGimsey received an undergraduate degree in geology at the University of North Carolina, then landed an internship(实习期) with a geologist at the USGS(美国地质勘探局) whose work field was about volcanoes. After earning a graduate degree at the University of Colorado, McGimsey accepted a job with the USGS and has been with the Alaska Volcano Observatory for 25 years.

Volcanoes can influence the world in ways we might not think about. For example, on Dec.15 1989, a 747 jetliner (a large airplane) flew through a thick ash cloud produced by Mount Redoubt, an Alaskan volcano that hadn’t erupted in 25 years. The ash caused all four engines to die, and the plane’s electronics went dead.

“The plane was within several thousand feet of flying into the mountains below when the pilots got a couple of engines restarted and landed safely in Anchorage,” McGimsey says. It cost nearly $80 million to repair the damage to the plane.

Such situations show just how dangerous volcanoes can be. However, volcanologists know the risks and are prepared to protect themselves.

McGimsey admits, “There is certainly a higher danger level in volcanology than some other jobs. We understand how serious the danger is, and we don’t like taking unnecessary chances. We avoid getting too close to an erupting volcano, because it is not worth injury or death simply to get a rock or a photograph.”

1.Before working for the USGS, McGimsey ________.

A.had been a pilot for 25 years

B.knew nothing about the organization

C.had taught at the University of North Colorado

D.had studied at the University of Colorado

2.On Dec.15,1989, a 747 jetliner ________.

A.had all its engines restarted

B.flew into a volcano in Europe

C.survived an air accident luckily

D.disappeared in a huge ash cloud

3.What McGimsey says in the last paragraph shows his ________.

A. prideB. carefulnessC. lonelinessD. doubt

4.What would be the best title for the text?

A.Game McGimsey: a man of his word

B.Game McGimsey: a volcano watcher

C.The eruption of Mt Redoubt

D.Lost land of the volcano

“We are good mothers,” I said to my friend, as we sat on our comfortable beach chairs under our beach umbrella and watched our children playing in the waves.

Out of nowhere, the children took off running. About fifty yards from us, a man—maybe in his fifties—was fishing. The children stood next to him and watched with their little mouths hanging open as he cast the fishing lines. He smiled at them. They ran back to us—all except my three-year-old daughter, Drew.

My heart beat fast with horror. “Drew! Come here! Play with your friends!” I shouted, very aware that my speeches about not talking to strangers weren’t working. It seemed that many parents heard of horrible stories about children being taken away by strangers. Responsible mothers should teach their children that the world is a dangerous place. So I felt relieved (松口气) when Drew ran towards me and took hold of a shovel (铲子). Then she looked me in the eye: “I want to be with the person.”

Again, she approached the middle-aged man, and started digging next to him.

Several seconds later, she returned, waving something shiny.

“Look, Mommy! A toy fish!”

It was, indeed, a toy fish—yellow and rubber. This must have been what he was using to attract the fish. And he’d given it to Drew. The three other children were deeply impressed, and they didn’t try to hide how jealous(妒忌的)they were—clearly, they all wanted the fish.

“My friend gave me that fish!” Drew shouted loudly. The sand in front of the umbrella turned into a preschool cage match with a yellow rubber fish flying through the air. I felt like I might cry myself.

Unexpectedly, there he was: the man, standing right next to us with three more rubber fish in hand. He handed them to each of the children. By their faces, you would have thought he was actually the really kind big brother.

“Thank you,” I said, realizing that there is good and kindness in strangers.

C. the toy fish was covered with sand

D. the stranger appeared from nowhere

A. Give a kid a fish

B. We are good mothers

C. The world is dangerous

D. Teach kids to be kind

Those who are used to looking through thousands of books in big bookstores may find Japan’s Morioka Shoten a little strange. That’s because this tiny bookstore that is located in Ginza, Tokyo sells only a single book at a time.

Opened in May 2015, Morioka Shoten is the brainchild of Yoshiyuki Morioka. The experienced bookseller began his career as a bookstore clerk in Tokyo’s Kanda district before branching out to open his own store. It was here while organizing book readings that he realized that customers usually came into the store with one title in mind. Morioka began to wonder if a store could exist by selling many copies of just one single book. In November 2014, he partnered with his two friends, to establish a unique bookstore with the idea of “A Single Room, A Single Book.”

Like its offering, the bookstore is simple. The selections that are picked by Morioka change weekly and vary widely to attract customers with different interests. Recent choices include The True Deceiver, an award-winning Swedish novel by Tove Jansson, Hans Christian Andersen’s Fairy Tales, and a collection of artist Karl Blossfeldt’s photography of plants. Morioka has also chosen books written by famous Japanese authors Mimei Ogawa and Akito Akagi.

To highlight his only offering, Morioka often uses clever methods. For example,when selling a book about flowers, he decorated his shop with the ones that had been mentioned in the book. He also encourages authors to hold talks and discussions so they can connect with customers. Morioka says his goal is for the customers to experience being inside a book, not just a bookstore!

Risky as the idea might seem, things appear to be going well. Morioka says he has sold over 2,100 books since he opened it. Things can get better considering that (考虑到) his bookstore is becoming increasingly popular not just among the locals but also visitors from other countries.

1.What inspired Morioka to open such a bookstore?

A. A Swedish novel

B. His present partner

C. A bookstore clerk

D. His working experience

2.Why is Morioka Shoten unique?

A. It is popular with foreigners .

B. It sells books of different topics.

C. It is decorated with colorful flowers.

D. It sells various copies of a book in a week.

3. Why does Morioka encourage authors to hold talks?

A. To introduce his bookstore.

B. To advocate(倡导) his philosophy.

C. To make books better understood.

D. To help readers connect with each other.

4. What’s the author’s opinion about the bookstore’s future?

A. Risky B. Optimistic

C. Unpredictable D. Hopeless

For most caffeine(咖啡因)consumers, its main benefit is that it helps you get more done. This is what makes it unusual, says Stephen Braun, author of Buzz: The Science and Lore of Alcohol and Caffeine.

“Its appeal is that it helps us earn more money,” he adds. “What makes it different from other drugs is that it’s used as a productivity tool –– not for pleasure.”

Many of history’s creative minds have also been connected with a large amount of caffeine consumption (消耗).

According to one biographer, the French novelist and playwright Balzac drank as many as 50 cups of coffee a day. “Were it not for coffee one could not write, which is to say one could not live,” he once insisted.

For seven years, the film-maker David Lynch ate at the same Los Angeles diner every day, drinking up to seven sweetened cups of coffee “with lots of sugar” in one sitting, which he said would guarantee that “lots of ideas” arrived.

Ludwig van Beethoven was said to have painstakingly counted out exactly 60 coffee beans per cup when he brewed(煮)coffee.

Perhaps recent tales of caffeine excess (过量) featured the singer Robbie Williams, who reportedly consumed 36 cups of black coffee and 20 cans of Red Bull a day.

It is the routine task itself, as much as the stimulating(刺激的)effects of caffeine, that makes the process so important, says Mason Currey, author of Daily Rituals: How Artists Work. “A lot of artists use the process of making coffee as a gateway to the creative process,” he adds. “You need to get into the right mindset to do that sort of work, and the preparation process provides a focus.”

One problem with attempting to control caffeine, says Braun, is that it affects everyone differently –– it is impossible to work out a “safe” limit that works for everyone. “Eventually, you have to become your own scientist –– there isn’t an alternative to careful self-experimentation,” he says.

1.The examples of some famous people are given to show that _______.

A. most artists like drinking coffee

B. drinking coffee helps artists make more money

C. there’s a link between drinking coffee and creating ideas

D. drinking coffee makes artists become more successful

2.What leads to the artists’ creative process according to Mason Currey?

A. Being lost in thought. B. Drinking the coffee.

C. Brewing the coffee. D. Getting a good mindset.

3.What does Braun advise us to do in the end?

A. To drink less coffee.

B. Never to limit caffeine use.

C. To work out a safe level of caffeine use.

D. Never to take more coffee than you need.
