If you knew a bottle of water had been recycled from urine (尿), would you drink it? Astronauts at the International Space Station (ISS) may soon do so. NASA (美国航空航天局) said it would use a high-tech machine (高科技机器) to recycle wastewater at the ISS. The machine will recycle everything from sweat (汗), the water for washing hands, shower water, water used for brushing teeth, and even urine, to make drinking water.

It will save NASA millions of dollars each year. At present, each ISS astronaut uses about 4.4 liters (升) of water every day. It costs about $24 million a year to transport water up to ISS. NASA says that a liter of water costs about $11,000.

The machine will be sent to the ISS in October 2008. NASA hopes it will recycle about 93% of all water used on the station. Will the water be clean? Scientists say the wastewater will go through a very complicated process (复杂的过程). For example, different chemicals will be put in the wastewater; the water will be heated to 130℃to get rid of bacteria (细菌). The recycled water is thousands of times better than the water from a city tap, scientists say.

Sometimes I really doubt (怀疑) whether there is love between my parents. Every day they are busy trying to make money in order to pay for my brother's education and mine. They don't act in the romantic ways that I read in books or I see on TV. For them, “I love you” is too difficult to say. Even sending flowers to each other on some special days is hardly ever seen.

One day, my mother was repairing a quilt. I silently sat beside her and looked at her. “Mom, may I ask you a question?” I said. “What?” she replied, still doing her work. “Is there love between you and Dad?” I asked her in a very low voice. My mother stopped her work and looked at me in surprise. She didn't answer my question at once. Then, she bowed her head and continued to do her work.

I was afraid that I had hurt her feelings. I felt so embarrassed that I didn't know what to do. But at last I heard my mother say the following words:

“ Look at this thread (线). Sometimes it appears, but most of the time, it hides in the quilt. The thread really makes the quilt strong and durable. If life is a quilt, then love should be a thread. It can hardly be seen anywhere or anytime, but it's really there."

I couldn't understand her until the next spring. At that time, my father suddenly got sick seriously. My mother had to stay with him in the hospital for a month. When they returned from the hospital, they both looked very pale. After they were back, every day in the morning and dusk, my mother helped my father walk slowly on the country road. My father had never been so gentle. The doctor had said my father would recover in two months. But after two months he still couldn't walk by himself. All of us were worried about him. "Dad, how are you feeling now?" I asked him one day. "Susan, don't worry about me." he said gently. "To tell you the truth, I just like walking with your mom. I like this kind of life." Reading his eyes, I know he loves my mother deeply.

Once I thought love meant flowers, gifts and sweet kisses. But from this experience, I understand that love is just a thread in the quilt of our life. Love is inside, making life strong and warm.
