Scientists in Britain have managed to teach bees to pull strings (线) to get to food and then pass on what they have learned to others in their colony (群体) — showing a high level of intelligence despite their tiny brains.
Researchers at Queen Mary University of London said the experiments, often used to test the intelligence of apes (猿) and birds, showed for the first time that some insects are up to the task, and can also pass skills on through several generations.
The findings add to the evidence suggesting the ability for “culture spread”— the ability to learn and pass on knowledge and skills — may not be exclusive to humans.
In the research, published in the journal PLOS Biology on Tuesday, the scientists were able to train 23 out of a group of 40 bees to pull strings with their legs and feet.
The strings were attached to discs — or artificial “flowers”— containing food at their center but placed under a transparent (透明的) screen. The bees, spotting the food beneath the screen, learned to pull the “flowers” out by pulling the string with their legs and feet to be able to get to it.
From another group of bees given the chance to solve the task without any training, only two of 110 were successful.
Another group of bees was then allowed to observe the trained bees pulling the strings, and 60 percent of them successfully learned the skill. Finally, trained bees were put in colonies, and the scientists found the technique spread successfully to a majority of the colony's worker bees.
Lars Chittka, a Queen Mary University professor who guided the project, said the team is interested in figuring out the brain processes behind the bees' learning and teaching skills.

Jimmy is an automotive mechanic (汽车修理技工), but he lost his job a few months ago. He has a good heart, but always feared applying for a new job.
One day, he gathered up all his strength and decided to attend a job interview. His appointment was at 10 a.m. and it was already 8:30. While waiting for a bus to the office where he was supposed to be interviewed, he saw an elderly man wildly kicking the tyre of his car. Obviously there was something wrong with the car. Jimmy immediately went up to lend him a hand. When Jimmy finished working on the car, the old man asked him how much he should pay for the service. Jimmy said there was no need to pay him; he just helped someone in need, and he had to rush for an interview. Then the old man said, “Well, I could take you to the office for your interview. It’s the least I could do. Please, I insist.” Jimmy agreed.
Upon arrival, Jimmy found a long line of applicants waiting to be interviewed. Jimmy still had some grease (油渍) on him after the car repair, but he did not have much time to wash it off or have a change of shirt. One by one, the applicants left the interviewer’s office with disappointed looks on their faces. Finally his name was called. The interviewer was sitting on a large chair facing the office window. Rocking the chair back and forth, he asked, “Do you really need to be interviewed?” Jimmy’s heart sank. “With the way I look now, how could I possibly pass this interview?” He thought to himself.
Then the interviewer turned the chair and to Jimmy’s surprise, it was the old man he helped earlier in the morning. It turned out that he was the General Manager of the company.
“Sorry I had to keep you waiting, but I was pretty sure I made the right decision to have you as part of our workforce (职工) before you even stepped into this office. I just know you’d be a trustworthy worker. Congratulations!” Jimmy sat down and they shared a cup of well-deserved coffee as he landed himself a new job.
1.What did Jimmy see on the way to the interview?
A.A friend’s car had a flat tyre. B.A wild man was pushing a car.
C.A terrible car accident happened. D.An old man’s car broke down.
2.How did Jimmy feel on hearing the interviewer’s question?
A.He was sorry for the other applicants. B.There was no hope for him to get the job.
C.He regretted helping the old man. D.The interviewer was very rude.
3.What can we learn from Jimmy’s experience?
A.Where there’s a will, there’s a way. B.A friend in need is a friend indeed.
C.Good is rewarded with good. D.Two heads are better than one.
The Origins of Famous Brands
Our lives are full of brand names and trademarked products that we use every day. Although many brand names are simple acronyms(首字母缩略词) or versions of their founders' names, some of the companies we trust every day actually have fascinating and surprising back stories.
Starbucks
It seems fitting that the most famous coffee brand in the world would take its name from one of the world's greatest works of literature. The inspiration for the name of the coffeehouse came from Herman Melville's Moby Dick. The founders' original idea was to name the company after the Captain Ahab's ship — Pequot, but they eventually decided that Pequot wasn't a great name for coffee, so they chose Ahab's first mate, Starbucks, as the name instead.
Nike
Originally founded as a distributor for Japanese running shoes, the company was originally named BRS, or Blue Ribbon Sports. In 1971, BRS introduced its own soccer shoe, a model called Nike, which is also the name for the Greek goddess of victory. In 1978, the company officially renamed itself as Nike, Inc.
The right name is essential to a company's success, and a great origin story is just as crucial as a great product. An attractive origin story is one more thing that keeps customers guessing, wondering, and buying its products.
Google was originally called BackRub, for it searched for links in every corner of the Web. In 1997, when the founders of the company were searching for a new name showing a huge amount of data for their rapidly improving search technology, a friend suggested the word “googol”. When a friend tried to register the new domain name, he misspelled “googol” as “google”.

2.When did the Nike get its name eventually?
A.In 1971. B.In 1978. C.In 1997. D.In 1987.
