Scientists have been studying how people use money for long. Now they’re finding some theories may apply to one group of monkeys.

Researchers recently taught six monkeys hos to use money. They gave the monkeys small metal disks (圆片) that could be used like cash and showed them some yummy apple pieces. The monkeys soon figured out that if tyey gave one of the disks to a scientist, they’d receive a piece of apple in return.

If you think that is all the monkeys can figure out, you are wrong. Two researchers, Jake and Allison, acted as apple sellers in the experiments. The monkeys were tested one at a time and had 12 disks to spend in each experiment. Jake always showed the monkeys on apple piece, while Allison always showed two pieces. But that’s not necessarily what they gave the monkeys. The number of apple pieces given for a disk was determined at random.

Experiment One: Allison showed two pieces of apples but gave both piece only half the time. The other half, she took one piece away and gave the monkey just the remaining piece. Jake, on the other hand, always gave exactly what he showed: one piece for each disk. The monkeys chose to trade more with Allison.

Experiment Two: Allison continued to sometimes gave two pieces and sometimes one piece. But now, half the time, Jake gave the one apple piece he was showing, and half the time he added a bonus. Guess what? The monkeys chose to trade more with Jake.

In the first experiment, the monkeys correctly figured out that if they traded with Allison, they’d end up with more treats. In the second one, when a monkey received two pieces from Jake, it seemed like a gain. When Allison gave the monkey only one piece instead of the two she showed, it seemed like a loss. The monkeys preferred trading with Jake because they’d rather take a chance of seeming to win than seeming to lose.

We also sometimes make silly business decisions just to avoid the feeling that we’re getting less, even when we’re not. Would you have made the same choices?

1.What conclusion might experts draw from the first experiment?

A. People are smarter in terms of finance.

B. It’s easy to teach monkeys how to trade.

C. Business theories can apply to all monkeys.

D. The monkeys show certain business sense.

2.What does “a bonus” in paragraph 5 refer to?

A. A coin.　　 B. A chance.

C. A metal disk.　　 D. An apple piece.

3.Why did the monkeys choose to trade more with Jake in the second experiment?

A. Because they didn’t like the feeling of losing.

B. Because they get more apple pieces from Jake.

C. Because Jake always gave them two apple pieces.

D. Because the apple pieces from Jake were yummy.

4.What could be the best title for the passage?

A. Disk for Apple: Who to Trade with?

B. Shopping for Bargain: Same of different?

C. Moneky’s Business Sense: Smart or Silly?

D. People’s Business Decision: Lose or Gain?

Market analysts in the United States have recently been quoted as saying that the biggest threat to the luxury (奢侈品) industry in the US is the tech industry. This is according to an article by fellow journalist Ashley Lutz. Her suggestion is sound. The main idea of her article is that products from Tiffany & Co. find their biggest competition not from other luxury brands but from companies like Apple. Lutz points out that luxury products are often only for “show,” while the attraction behind tech products is functionality.

You find few people in the United States today willing to purchase luxury goods at full price. It didn’t use to be that way. Luxury goods used to be actually exclusive. That meant you needed to travel to the right store to purchase them, and you didn’t even have the option of getting a deal.

Today, no one wants to pay full price for luxury goods. People have the unfortunate belief that fakes (赝品) somehow are equal to originals, and if you can’t get a deal on eBay, Amazon, or in an outlet store, purchasing a luxury product probably isn’t worth it. Luxury brands struggle to remain high-end (高档的) images despite the reality that the American consumer is motivated much more by discounts than they are by brand names or image.

Yet people stand in line to pay full price for a new product from Apple and crowds gather to hear about a new smart phone. While electronics are updating every day, people are purchasing technology at full prices much more than they are purchasing luxury goods. What are high-tech makers doing right that luxury makers are pitifully failing at?

Carefully looking at the situation, it would appear as if the Internet didn’t hurt the luxury industry, expectation from the consumers did. What people want these days more than anything is stuff that does something. They want cars that drive, shoes that are comfortable, games that are fun to play, screens that are beautiful to look at, tools that are useful, and entertainment that is entertaining. Little of that fits into what the luxury industry has typically offered with its status, image, and fine materials. The sad reality is that luxury products aren’t that luxury any more.

1.What does this passage mainly talk about?

A. Nobody likes luxury goods any more.

B. Tech products become the new “luxury goods”.

C. Luxury goods are of poor quality nowadays.

D. Iphones have taken the place of luxury products.

2. The underlined word “exclusive” in paragraph 2 means _______.

A. easy to sell

B. low in price

C. hard to find

D. unique and with no bargain

3.What do people pay most attention to nowadays?

A. The function of products.

B. The images of luxuries.

C. The Internet service.

D. The expectation from the consumers.

The fact that ants are fascinating insects has been known for some time. Now, scientists have discovered a large number of wood ants living in an abandoned underground storehouse in Templewo, Poland, despite having no obvious source of food.

Polish zoologist Wojciech Czechowski and his team began studying the underground colony in 2013. They found the ants built a 60-cm high nest in the soil directly over the storehouse vertical air pipe. As years passed, the metal covering on the pipe eroded, leaving behind a hole that thousands of worker ants accidentally slip into each day as they go about their daily chores. The scientists say that there are no sources of food in the storehouse. This means that the insects live in a state of near starvation.

In July 2015, the researchers disturbed part of the ant nest in search of larvae (幼虫), cocoons(茧), and queens. They found nothing, leading them to suspect that the lack of food and cold temperatures made reproduction impossible and that the group tending the nest is entirely made up of non-reproductive female workers. Their population is refilled every year, by a new rain of unfortunate ants that slide down the hole. The researchers say that when they returned in January 2016, the nest had been repaired. It appears that despite the terrible conditions, the worker ants do not stop constructing their nest.

Wood ants are known for their ability to adapt to bad living conditions. In this case, the millions of worker ants trapped in the storehouse have no choice. But instead of losing hope, they are making the best of the situation—a classic example of “when life gives you lesions make lemonade.”

1.How did the wood ants arrive in the storehouse?

A. They fell down there by accident.

B. The research team brought them there.

C. The storehouse builders left them there.

D. They were attracted by the environment.

2.What does the underlined word “eroded” in Paragraph 2 probably mean?

A. Expanded.　　 B. Rotted.

C. Exploded.　　 D. Melted.

3.What did the researchers find in the nest?

A. Larvae.　　 B. Cocoons.

C. A queen.　　 D. Worker ants.

4.Why did the population of wood ants remain steady?

A. They had enough food.

B. They were able to reproduce.

C. They adapted to the conditions.

D. They had new comers to join them.

Scientists have created a “ human-like robot” that can dance and do the housework.

“ Mahru” has been developed to imitate humans and can move its lips, eyebrows and pupils(瞳孔). The machine can also move its upper and lower body freely and automatically stop itself when walking.

In addition, it has been programmed to give out two kinds of pleasant smells to match its emotions.

The 1.5 tall robot was produced by researchers at the Korea Institute of Science and Technology (KIST) and is the first South Korean- developed machine of its kind.

“‘Mahru’ will open the way for the commercial use of humanoid robots doing housework,” You Bum-Jae, leader of the development research team ,said. “‘Mahru’ can dance while walking on its legs and is able to work in place of a human.”

Through an advanced motion capture (捕获) system, “Mahru” can follow a variety of human movements and move its hands freely enough to deal with any obstacles that may get in its way when walking.

State-funded KIST showed the robot during a presentation at its head office in Seoul.

People here were treated to an entertaining demonstration which saw the robot show off the full range of its skills, most notably s series of dance moves.

The research team added that they had designed another “ Mahru”, this time with sensors(传感器) allowing it to distinguish(分辨) between faces and objects.

The showing of “ Mahru” came a week after researcher in Japan said they had created the “most human-like” robot in the world. A team at robotics department of Osaka University in Japan claimed that “ robogirl”, Repliee R-1, “ looks, moves and interacts (相互作用) like a human, and has silicone(硅胶) skin that feels almost human to the touch.”

1. “Mahru” made by KIST can do the following things EXCEPT____________

2. According to what You Bum- Jae said in Paragraph 5, his research team wants to ________.

3. When Mahru” meets something in its way, it will be likely to________.

A Canine Reading Buddy

Dogs and people have developed a special bond over time. Recently, however, some dogs have taken a different role in people’s lives—therapy dogs.

1. Some therapy dogs visit patients in hospitals or nursing homes, while others visit children in schools and libraries. They are there to help children become better readers.

Reading programs that use therapy dogs have been in existence for more than ten years. All therapy dogs of this program are registered with an organization that tests the dogs to make sure they have the right personality for the job.

2. Both the dogs and the handlers are volunteers with the reading program.

At the start of a reading therapy session, a child and a dog are introduced. The pair is allowed to settle down in a quiet corner together. 3. An adult handler stays nearby but generally lets the dog perform its job without interfering(干涉). Sometimes, a handler may ask a question that encourages the child to work with the dog to help the child feel more comfortable.

Not every child will be able to be part of a reading therapy program that uses dogs. A few children might be allergic to dogs or afraid of them; some children might have cultural traditions that prevent them from touching a dog. 4.

Reading therapy programs inspire learning and change. 5. They spend time with human friends. For dogs that love human companionshiop and a quiet place to rest, being part of a reading therapy program can be a great way to spend a few hours each day. The readers benefit too, gaining confidence and learning that reading aloud can be a relaxing experience.

A. How do the therapy dogs benefit from it?

B. But therapy animals also serve in many other areas.

C. As the child reads, the dog usually lies quietly and listens.

D. When reading to an animal, some children may become relaxed.

E. In these circumstances, other animals are available, such as cats and parrots.

F. A therapy dog is more of a companion and is trained to help people in different ways.

G. A dog’s handler also takes a class and must pass a test to work in the therapy program.
