【题目】【原创】A bit shocked with the current rise of airfares? They have gone up not 3% or 5%, but 10%, and sometimes even higher! Yes, its sad; conventional traveling has become almost unaffordable to most of us travel junkies(旅游迷)。But heres the good news! Theres a chance you can travel for free! In fact, you can even get paid while doing so. Its true. Below are some clever suggestions that you can try to get paid while traveling.

1.Work as a Tour Guide

If you love mingling and hanging around with people, this one is perfect for you. As a tour guide, you can see and study different cultures while leading tourists to historic places around the world. And you can have a substantial income while enjoying foreign cultures. There are always two sides to a coin, though.

2. Teach English

Latin America, the Middle East and Asia have abundant jobs for English teachers. If you are bent on having a cultural and educational trip to a land that has mystified(使惊奇)you for the longest time, teaching could be the thing that can carry you through. In many cases, youre not required to be certified. Your students just need to know one thing --- that youre a native speaker.

3. Become a Travel photographer

For those who are camera experts, theres a huge opportunity to sell the travel photos that they take. One way is to set up a shop on websites. Via these platforms, you can sell photos either to a variety of travel magazines, or to business organizations with stock photography collections.

4.Bcome a Flight Attendant

You can also choose to get a nine-to-five job. A great option is working as a flight attendant. These flying professionals make around $25,000 to $50,000 a year. They get fantastic travel benefits which include going on trips with family members if they choose to. The salary may be a bit in the lower range, but remember that the average time on the job for attendants is about hours per month. Cool, isnt it?

【题目】 Its well known that our human memory can fail us. People can be forgetful, and they can sometimes also remember things incorrectly, with damaging consequences in the classroom, courtroom, and other areas of life. Now, researchers show for the first time that bumblebees(大黄蜂) can be unreliable witnesses too.

Bumblebees are rather clever animals, which explains why Chittka has been studying learning and memory in the insects for the last 20 years.

Most times when people have studied memory in animals, errors in performance have been taken to mean that the animals failed to learn the task or perhaps learned it and then forgot. But what if animals can experience a more interesting type of memory failure?

To find out, Chittka first trained bumblebees to expect a reward when visiting a yellow artificial flower followed by one with black-and-white rings. During subsequent tests, bees were given a choice between three types of flowers. Two were the types theyd seen in the training before. The third had yellow-and-white rings, representing a mixed-up version of the other two. Minutes after the training, the bees showed a clear preference for the flower that recently rewarded them.

One or three days later, however, something very different happened when the bumblebees memory was put to the test. At first, the bees showed the same preference displayed in the earlier tests, but as the time went on, they began selecting the flower with yellow rings, even though theyd never actually seen that one in training before.

Chittka says that insects make similar errors in the conjunction (结合) of long-term memories as humans do. The ability to extract (提取) common features between different events in the environment might come at the expense of remembering every detail correctly. In bees, with their limited brain capacity (容量), the pressure to store main features of several objects rather than each individual object might be much greater, compared with humans.
