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.
1.Which of the following can replace the underlined word “exclusive” in Paragraph 3?
A.Ordinary. B.Limited. C.Beneficial. D.Widespread.
2.What did the researchers find about bees?
A.Bees learn best in insects. B.Bees are as clever as birds.
C.Bees are born good learners. D.Bees can be trained to learn skills.
3.What may the research team focus on next?
A.What else bees can do. B.Where bees learn skills.
C.How bees teach others. D.How bees' brains work.
4.What may be the best title for the text?
A.Small Bees, Great Abilities B.Bees Can Learn and Teach

There are plenty of different parks to visit in the UK. All theme parks in Britain have cafes, restaurants, picnic areas and gift shops, so you’ll still have plenty to see and do when you and the kids have been on enough rides. There are usually smaller “funfair” rides and games as well, so younger children won’t get bored. Several theme parks also have other attractions next to them, e.g. water parks often open all year round, unlike the theme parks.
Wherever you are in Britain, there’s likely to be a theme park within one or two hours’ drive, bus ride or train journey. Several theme parks even have accommodation(膳宿) so you can stay for a day or two if you want to make a trip into a short holiday.
Prices for UK theme parks vary considerably; some have an entrance price which allows you to go on all the rides, while in others you have to pay for every ride individually. It can also make a difference whether you go during peak time or not. For example, tickets always cost more during school holidays and weekends than they do during the weekdays.
Theme parks always get very busy during the summer months, so if you don’t like crowds, it’s usually a good idea to go earlier or later in the year!
If you’re thinking of visiting a UK theme park, it’s worth having a look for special offers on tickets. Products such as chocolate bars and cereals sometimes have “buy one get one free” offers on theme park tickets, so keep a look out in shops and supermarkets.
