Butterflies are some of the most fascinating and beautiful insects in the world. Adult butterflies will live about 2 to 4 weeks. They use their senses of sight, touch, hearing, smell, and taste to survive in the world, find food and mates, lay eggs in an appropriate place, migrate, and avoid hungry enemies.
Butterflies have large compound eyes(复眼), which allow them to see in all directions without turning their heads. Like most insects, butterflies are very nearsighted, so they are more attracted to a sea of flowers than individual plants. Butterflies do not “see” colors such as red, green, and yellow, but they can sense sunlight, which indicates the direction the sun is shining, as well as ultraviolet light（紫外线）, which is present on many flowers and guides butterflies to honey sources.
Butterflies have a very well-developed sense of smell, but it is not in their nose, since they don't have one. Sense receptors are located in their antennae（触角）, feet, and many other parts of the body. They can help butterflies find their favorite flower honey food, and mates.
Butterflies' feet have sense organs that can taste the sugar in flower honey, letting the butterflies know if something is good to eat or not. Some females also carefully choose host plants by tasting to find appropriate places to lay their eggs. Adult butterflies feed their babies using a long tube. Butterflies force blood into the tube to straighten it out, allowing them to feed. Butterflies get all their food from this tube.
Butterflies don't have ears. Instead they “hear” sounds through their wings by sensing changes in sound vibrations（振动）.
Butterflies may possess senses we don't even know about yet, because their body structure is very different from ours, and therefore difficult to understand, when observed through our own human senses.

When 15-year-old Louisa Ball takes a nap, she sleeps for days on end, and no amount of shaking can fully wake her up. The British girl has a rare condition called Sleeping Beauty Sickness. Doctors don’t know what causes it or how to cure it --only know that it strikes teenagers and goes away by itself after eight to 12 years.
Louisa’s mum, Lottie, told NBC News that the girl had flulike symptoms just over a year ago. Shortly afterward, she had her first period of long sleeping.
She was eventually diagnosed with Kleine-Levin Syndrome, whose victims worldwide may number no more than 1,000. The victims live normally for weeks or months at a time, with normal sleep patterns and normal energy levels. Then, with little warning, they’ll go to sleep for days or weeks at a time. So far, Louisa’s longest period in bed has been 13 days. Victims will wake briefly, but be disoriented and not fully awake. Louisa’s parents force her awake so she can use the bathroom and eat.
Now, Louisa’s friends can tell when a period is coming on. She stops talking and she may be annoyed easily. That’s when she knows she has to get home to her bed. Louisa has slept through family vacations, the dance recitals(表演会) she loves to perform in, and school tests. Now it becomes increasingly difficult to catch up on missed schoolwork.
But just as doctors don’t know the cause, they also don’t know why it ends as mysteriously as it began. The illness is unrelated to narcolepsy(嗜眠病), whose victims are constantly tired and drop off for brief periods of sleep at any time.
It’s so dramatic that some people have accused Louisa of making the false symptoms to get attention. Her father, Richard, thinks that’s absurd.

Every day, Daisy wakes up next to a man, who has to convince her they are married. When she expresses doubt, he takes out a photo album and shows her pictures of their wedding 13 years ago.

I lived in a big city in Australia and I used to give much money to the homeless around, feeling sorry for their misfortune. But later I became a single mom with no home, a huge and hardly any income. As a result, I stopped giving and became very .
Things started to change. I became enough to have a home, and even a backyard, and I started to pull myself out of debt. One day we saw a person with the sign, “Will work for food.” I . My daughter asked why I no longer helped the people in . I replied, “Honey, they just use that money for or other bad things.” She didn’t respond. But when I said that, it didn’t feel right.
Three days later, I was to pick up my daughter from school. A man was standing on the corner and something deep inside my heart drove me to help him. So I stopped my car, and he ran over with . He said, “God bless you, I only need 77 cents.” I reached into my ashtray（烟灰缸） and enough, there sat 3 quarter and 2 pennies.
Greatly shocked by this , I gave him all the money in the ashtray. He tears with joy, “You just made it for me to see my mom for Christmas! The bus this great sale is leaving right away!”
