One kind of female butterfly mates only once in its life -- and then closes its wings to avoid "harassment" when pursued by persistent and unwanted males, a Japanese researcher said.
Observations of the Small Copper Butterfly, a colourful orange and black butterfly, showed that some females closed their wings when males flew by, but only when they were males of their own species, said Jun-Ya Ide, an associate professor at Kurume Institute of Technology in Fukuoka, western Japan.
"When we looked into why, the males were courting the females. They do this very stubbornly, so the females sometimes try to get away -- or prefer to stay unobserved," he added.
Ide and his colleagues brought a model of a male butterfly near the females to test their reactions and found that young females that had yet to mate kept their wings open, but those that had already mated closed them.
Not only can the persistent attentions of unwanted suitors harm the delicate females, fleeing from them -- with the male often in pursuit -- uses up strength and can even shorten their lives, he added.
"Closing their wings makes them less visible, helping them avoid communication with their own species. We figured they were trying to avoid harassment by males," Ide said.What does the word “harassment”mean in the paragraph？

Are you sometimes a little tired and sleepy in the early afternoon? Many people feel this way after lunch. They may think that eating lunch is the cause of the sleepiness. Or, in summer, they may think it is the heat. However, the real reason lies inside their bodies. At that time – about eight hours after you wake up – your body temperature goes down. This is what makes you slow down and feel sleepy. Scientists have tested sleep habits in experiments where there was no night or day. The people in these experiments almost always followed a similar sleeping pattern. They slept for one long period and then for one short period about eight hours later.
In many parts of the world, people take naps(小睡) in the middle of the day. This is especially true in warmer climates(气候), where the heat makes work difficult in the early afternoon. Researchers are now saying that naps are good for everyone in any climate. A daily nap gives one a more rested body and mind and therefore is good for health in general. In countries where naps are traditional (传统的), people often suffer less from problem such as heart disease.
Many working people, unfortunately, have no time to take naps. Though doctors may advise taking naps, employers do not allow it! If you do have the chance, however, here are a few tips about making the most of your nap. Remember that the best time to take a nap is about eight hours after you get up. A short sleep too late in the day may only make you feel more tired and sleepy afterward. This can also happen if you sleep for too long.

It was the summer of 1965. DeLuca, then 17, visited Peter Buck, a family friend. Buck asked DeLuca about his plans for the future. “I’m going to college, but I need a way to pay for it,” DeLuca recalls saying. “Buck said, ‘You should open a sandwich shop.’”
That afternoon, they agreed to be partners. And they set a goal: to open 32 stores in ten years. After doing some research, buck wrote a check for $1000. DeLuca rented a storefront (店面) in Connecticut, and when they couldn’t cover their start-up costs, Buck kicked in another $1000.
But business didn’t go smoothly as they expected. DeLuca says, “After six months, we were doing poorly, but we didn’t know how badly, because we didn’t have any financial controls.” All he and Buck knew was that their sales were lower than their costs.
DeLuca was managing the store and going to the University of Bridgeport at the same time. Buck was working at his day job as a nuclear physicist in New York. They’d meet Monday evenings and brainstorm ideas for keeping the business running. “We convinced ourselves to open a second store. We figured we could tell the public, ‘We are so successful, we are opening a second store.’” And they did—in the spring of 1966. Still, it was a lot of learning by trial and error.
But the partners’ learn-as-you-go approach turned out to be their greatest strength. Every Friday, DeLuca would drive around and hand-deliver the checks to pay their suppliers. “It probably took me two and a half hours and it wasn’t necessary, but as a result, the suppliers got to know me very well, and the personal relationships established really helped out,” DeLuca says.
And having a goal was also important. “There are so many problems that can get you down. You just have to keep working toward your goal,” DeLuca adds.
