Plants are very important living things. Life could not go on if there were no plants. This is because plants can make food from air， water and sunlight. Animals and man cannot make food from air， water and sunlight. Animals get their food by eating plants and other animals. Therefore animals and man need plants in order to live. This is why we find that there are so many plants around us.

If you look carefully at the plants around you， you will find that there are two kinds of plants： flowering plants and non-flowering plants. Flowering plants can make seeds. The seeds are protected by the fruits. Some fruits have one seed， some have two， three or four， and some have many seeds. But a few fruits have no seeds at all. An example of a fruit without seeds is the banana fruit. Most non-flowering plants do not grow from seeds. They grow from spores（胚芽）。 Spores are very small. Some spores are so small and light that they can float in the air. We may say that spores are quite the same as seeds. When these spores are all on wet and shady places， they usually grow into new plants.

Five years ago, David Smith wore an expensive suit to work every day. “I was a clothes addict,” he jokes. “I used to carry a fresh suit to work with me so I could change if my clothes got wrinkled.” Today David wears casual clothes—khaki pants and sports shirt—to the office. He hardly ever wears necktie. “I’m working harder than ever,” David says, “and I need to feel comfortable.”

More and more companies are allowing their office workers to wear casual clothes to work in the United States. The change from formal to casual office wear has been gradual. In the early 1990s, many companies allowed their employees to wear casual clothes on Friday(but only on Friday). This became known as “dress-down Friday” or “casual Friday.” “What started out as an extra one-day-a-week benefit for employees has really become an everyday thing,” said business consultant Maisly Jones.

Why have so many companies started allowing their employees to wear casual clothes? One reason is that it’s easier for a company to attract new employees if it has a casual dress code. “A lot of young people don’t want to dress up for work,” says the owner of a software company, “so it’s hard to hire people if you have a conservative dress code.” Another reason is that people seem happier and more productive when they are wearing comfortable clothes. In a study conducted by Levi Strauss and Company, 85 percent of employers said that they believe that casual dress improves employee morale(士气). Only 4 percent of employers said that casual dress has a negative impact on productive. Supporters of casual office wear also argue that a casual dress code helps them save money. “Suits are expensive, if you have to wear one every day,” one person said. “For the same amount of money, you can buy a lot more casual clothes.”

A. he often wore khaki pants and a sports shirt

B. he couldn’t stand a clean appearance

C. he wanted his clothes to look neat all the time

D. he didn’t want to spend much money on clothes

C. he looks handsome in casual clothes

D. he no longer works for any company

My grandfather came from Hungary and was the only one in his family who settled down in the United States. The rest of his family remained in Europe. When World War I broke out , he seemed to have become another man, downhearted. Such obvious change was not born out of his welfare, but out of fear if his only son, my uncle, had to go to war, it would be cousin fighting against cousin.

One day in 1918, my Uncle Milton received his draft notice. My grandparents were very upset. But my mother, at the age of 10, felt on top of the world about her soldier brother going off to war. Realizing how he was regarded by his little sister and all of her friends, my uncle bought them all service pins, which meant that they had a loved one in the service. All the little girls were delighted.

The moment came when my uncle and the other soldiers, without any training but all in uniforms, boarded the train. The band played and the crowd cheered. Although no one noticed, I’m sure my grandmother had a tear in her eye for the only son. The train slowly pulled out, but not about a thousand yards when it suddenly paused. Everyone stared in wonder as the train slowly returned to the station. There was a dead silence before the doors opened and the men started to step out. Someone shouted, “The war is over.” For a moment, nobody moved, but then the people heard someone bark orders at the soldiers. The men lined up in two lines, walked down the steps, and with the band playing, marched down the street, as returning heroes, to be welcomed home. My mother said it was a great day, but she was just a little disappointed that it didn’t last a tiny bit longer.

What the grandfather was most worried about was .

A. the spread of the world war B. the safety of his living two cousins

C. a drop in his living standards D. his relatives killing each other

The underlined phrase “draft notice” means “ ”.

A. order for army service B. train ticket for Europe

One day, she told me, “I think I 29 never leave the hospital,” she continued, “I just want to enjoy the little things--- 30 is out of the window.” We had never spoken of that before. 31 we began an African safari, a trip she had dreamed of for years.

Morning and afternoon, we went diving and rolled into the clear water 32 down like peas in honey. In the evenings, we spent time on the pier, watching the sun set.

We have been friends 34 than they have been alive.

35 dives, we talked about where to go next. I made lists 36 she slept. Our plans were now more theoretical, and the big trip to the South Pacific one day seemed a long way off. Cancer has become part of our 37 . We are well aware that our bodies are temporary gifts. Not knowing what comes next means 38 is possible. Perhaps I will be hit by a truck, or my heart will stop. Life is 39 .
