【题目】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 ars. 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.

【题目】When I was ten my dad helped me buy my first ten-speed bicycle from Allen. I put up $60 of my grass cutting and snow shoveling (铲) money and my dad put up the other half I would pay him back over the next six months. Although it was not in the latest style, it was my ticket to the adult world.

I spent that summer and autumn riding happily. My sister Liz, a prisoner of her five-speed bicycle, never had a chance to keep up. Just before the Christmas deadline to pay my dad back, we were hit with several snowstorms. This allowed me to shovel enough driveways (车道) to pay off my debt. I was now officially a bike owner; it was a feeling unlike any other.

On that Christmas morning, my dad gave me a used portable (便携式的) record player. I was excited. However, my joy was short-lived after my dad called my sister to the kitchen. “We have one more gift for you.” he said as he opened the door that led to the garage. There, on the steps, stood a new ten-speed bicycle.

“It’s not fair,” I complained. “I worked so hard for my bike and it’s not even new. Then Liz gets a new bike. She didn’t have to do anything for it. My dad smiled. “She didn’t have to do anything for it because it’ s not really for her,” he said. What did that mean? I didn’t want her bike.

By spring Liz and I were riding all over town together now that she could keep up. As we grew, Liz and I became true friends.

Still I wasn’t smart enough to figure out what my dad meant until years later. That new bike was not a gift for Liz it was a gift for me. He’d given me the gift of my sister’s company, the ability to stay together rather than drift apart (逐渐疏远) in the face of my ability to travel. He gave me my best friend.
