Of all the things we eat and drink, water is the most important. Not all people realize this, but it is quite true. The human body can live without food for a long time, but two or three days without water usually result in death.
Many people do not understand how much water the human body needs, but many people do not drink enough, especially in the hot weather. Most people drink when they are thirsty but often need more water after exercises.
65 to 70 percent of the human body is water. Water is important in several different ways. Most people need five to seven liters（升） of water every day, but we needn’t drink this amount(量) because a lot comes from the food we have. If we don’t have enough water, however, we will feel tired and many become ill. Do you know what the best drink is? Yes, you are right. Cool water!
【小题1】When do we need more water?________

Thirteen, for me, was a challenging year. My parents divorced and I moved to a new town with my father, far from my old family and friends. I was terribly lonely mad and would cry myself to sleep each night. To ease my sadness, my father purchased an old horse for me at a local auction. I named him Cowboy.?
Cowboy was without a doubt the ugliest horse in the world. But I didn’t care. I loved him beyond all reason.?
I joined a riding club and suffered rude comments and mean snickers(窃笑) about Cowboy’s looks. I never let on about how I felt, but deep inside, my heart was breaking. The other members rode beautiful, registered horses.?
When Cowboy and I entered the events where the horse was judged on appearance, we were quickly shown the gate. No amount of preparation and love would turn Cowboy into a beauty. My only chance to compete would be in the speed events. I chose the jumping race.?
One girl named Becky rode a big brown horse in the race events. She always won the blue ribbons. Needless to say, she didn’t feel threatened when I competed against her at the next show. She didn’t need to. I came in next to last.?
The stinging memory of Becky’s smirks made me determined to beat her. For the whole next month I woke up early every day and rode Cowboy five miles to the arena (赛马场). We practiced running and jumping for hours in the hot sun and then I would walk Cowboy home totally exhausted.?
All of our hard work didn’t make me feel confident by the time the show came. I sat at the gate and sweated it out while I watched Becky and her horse charge through the course and finish in first place.?
My turn finally came. I put on my hat, rubbed Cowboy’s neck and entered the arena. At the signal, we dashed toward the first fence, jumped it without trouble and raced on to the next one. Cowboy then flew over the second, third and fourth fences like a bird and I turned him toward the finish line.?
As we crossed the line the crowd was shocked into silence. Cowboy and I had beaten Becky and her fancy horse by two seconds!?
I gained much more than a blue ribbon that day. At thirteen, I realized that no matter what the odds, I’d always come out a winner if I wanted something badly enough to work for it.?

Moving to a new city and state was difficult for me, especially in winter. Little did I know that a Colorado snowstorm would greet me after I had been in my new home for only a week.
I just missed home. But more than the old house and the beach, I missed Stacey, my best friend. And I missed our lovely tea. Going to a sweet little tearoom, we had discovered was a special treat for us. The place was a Victorian dream, with delicate teacups and tablecloths with flower prints. The hat shelf near the front door swept us back to childhood. Stacey and I became little girls, trying on different hats until we found the perfect one for our dress-up tea party. We would then choose a lovely table and order our tea. That was a precious time, filled with laughter between scones（煎饼） and sharing our lives between tiny cucumber sandwiches.
Springtime descended upon Denver, and the sun lightened my heart. But I still fought loneliness almost every day. I decided to explore the Denver area. While my husband went to the office, I took time to see what our new area had to offer.
One day, I was walking along the street when suddenly the words "Tea Leaves" caught my eye. A tea room? Here, in the land of loneliness and pain?
I walked through the doors, and tears came to my eyes. It was a beautiful room, not Victorian, but simple and lovely.
I sat down and ordered a pot of tea, a cucumber sandwich, and some scones.It felt silly and wonderful --- and it felt like home. For the first time since moving, I felt as if this new city and state could be, would eventually be, my home. I would come back here and bring new friends. When Stacey visited, we would come here.
I lifted my cup and made a silent toast. I toasted Stacey, whom I missed  ly, and I toasted the sweet little tearoom that lessened my pain.

In a great many cities, hundreds of people ride bikes to work every day． In New York, some bike riders have even formed a group called Bike for a Better City． They declare that if more people rode bikes to work, there would be fewer automobiles in the downtown part of the city and so less dirty air from car engines．
For several years, this group had been trying to get the city government to help bike riders． For example, they want the city to draw special lanes(车道) for bikes on some of the main streets, because when bike riders must use the same lanes as cars there are accidents． Bike for a Better City feels that if there were special lanes, more people would use bikes．
But no bike lanes have been drawn． Not everyone thinks it is a good idea—they say it will slow traffic． Some store owners on the main streets don’t like the idea—they say that if there is less traffic, they will have less business．
The city government has not yet decided what to do． It wants to keep everyone happy． On weekends, Central Park—the largest place open ground in New York— is closed to cars, and the roads may be used by bikes only．

Many American presidents in the 19^th century were born in poor families. They spent their childhood in little wooden rooms. They got little education . Washington and Lincoln, for example, never went to school and they taught themselves. Lincoln once did jobs of a worker, shopkeeper and post officer in his early years.
A large number of U. S. presidents had experiences in the army. The two best known were Ulysses Grant and Dwight D. Eisenhower. Grant was a general (将军) in the American Civil War and Eisenhower was a hero in the Second World War. It happened that they graduated from the same school—West Point Military Academy . One may be surprised to learn that both of them did not do well in the school. Eisenhower, for example, was once fined (罚款) because he broke the rules of the school.
The jobs of U. S. presidents are tiring. He must keep an eye on anything important which happens both at home and abroad. Every day, a lot of work waits for him to do, and he has to make many important decisions. When Franklin Roosevelt was a child, he was once brought to visit President Taft. The old president said to him, “When you grow up, you should not be president. It’s a tiring job.”
