Astronauts aboard the space station celebrated a space first on Wednesday by drinking water that had been recycled from their urine(尿), sweat and water got from air. They said "cheers," clicked drinking bags and toasted NASA workers on the ground.
The urine recycling system is needed for astronaut stations on the moon and Mars. It also will have NASA money because it won’t have to ship up as much water to the station by space shuttles or cargo rockets. Besides, it’s important as the space station is about to expand from three people living on board to six.
The recycling system had been brought up to the space station last November by space shuttles Endeavour, but it couldn’t be used until samples(样品) were tested back on earth. So when it came time to actually drink up, NASA made a big deal of it. The three-man crew stood holding their drinks and congratulated engineers in two NASA centres that worked on the system.
“This is something that had been the stuff of science fiction,” American astronaut Michael Barratt said before taking a small mouthful. “The taste is worth trying.”
The new system takes the combined urine of the crew from the toilet, moves it to a big tank, where the water is boiled off, and the vapor(水蒸气) is collected. The rest of the urine is thrown away. Then the water vapor is mixed with water from air, and then it goes through filters (过滤器). When six crew members are aboard it can make about six gallons from urine in about six hours.
“Some people may find the idea of drinking recycled urine distasteful, but it is also done on earth, but with a lot longer time between urine and the tap,” said Marybeth Edeen, the space station’s national lab manager.
The technology NASA developed for this system has already been used for quick water purification after the 2004 Asian tsunami.
【小题1】 According to the text, the recycling system is important because ___________.

Directions: Complete the following passage by using ONE word that best fits the context.
Thanksgiving Day was near. The first grade teacher gave her class   48  fun assignment --- to draw a picture of something for which they were thankful.
Most of the class would celebrate the holiday with turkey and other traditional goodies of the season. These, the teacher thought, would be the themes of most of her students’ art. And they were. Douglas made a different kind of picture,   49 . When asked to draw a picture of something for which he was thankful, he drew a hand. Nothing else. Just an  50  hand .
His abstract image captured the imagination of his peers. Whose hand could it be? One child guessed it was the hand of a farmer, because farmers raise turkeys.   51  suggested a police officer’s, because the police protect and care   52  people. Still others guessed it was the hand of God, for God feeds us. And so the discussion went --- until the teacher almost forgot the young artist himself.
When the children had gone on to other assignments, she stopped at Douglas’ desk, bent down, and asked him 53  hand it was. The little boy looked away and said, “It’s yours, teacher.”
She recalled the times she had taken his hand and walked with him here or there, as she had the other students. How  54  had she said, “Take my hand, Douglas, we’ll go outside.” Or, "Let me show you how to hold your pencil.” Or, “Let's do this together.” Douglas was most thankful for his teacher's hand. Brushing aside a tear, she went on with her work.
The story speaks of more than thankfulness. It says something about teachers teaching and parents parenting and friends showing friendship, and how much it means to the Douglases of the world. They might not always say thanks,  55  they'll remember the hand that reaches out.

Professor Green, known to the world as a scientist, is not only absent-minded but short-sighted as well. His mind is always busy 41 scientific problems and seldom notices what is going on 42  him.
One fine day recently, he went  43 a walk in the countryside, but as 44  he has a book in his hand. When he went out , he began to read his book . He hadn’t gone far 45 he run into a big cow and fell down. In the fall, he had lost his glasses, without which he couldn’t see anything. He thought he had hit his head  46 a fat lady. “I’m sorry, Madam.” He said politely 47 searching for his glasses. As soon as he had 48 , he realized his mistake.
Soon he was fixing his mind on his book 49  and paid no attention to anything else. He had scarcely been walking for five minutes when he fell over again, _50 both his book and his glasses. This time he got very angry, seizing his umbrella, he gave the “cow” a wild blow. Then, after finding his glasses, he realized with horror that he made a second mistake. A large fat woman was fleeing from him in a horror.

If we observe carefully, we van find that most of the flowers in nature are red, orange and yellow. If we have seen a black flower, it’s a chance in million. People have made a census(普查)to colours of more than four thousand kinds of flowers and discovered that only eight of them are black. Why?
As we know, sunlight is formed by seven different kinds of coloured light. The wave length of each light changes, so the quantity of heat in each light changes, too. Flowers, especially their petals(花瓣), are very delicate(纤弱) and prone(易于) to the harm caused by high temperature. Black flowers can take in all the light waves, which cause the flowers to dry up in a high temperature. So black flowers can rarely survive sunlight. But red flowers, orange flowers and yellow flowers can protect themselves from sunlight by reflecting the red light, orange light and yellow light, each of which has a large quantity of heat.
That is why red, orange and yellow flowers are very common in nature while black flowers are so rare.
【小题1】We can hardly find black flowers because  _____.
