For the people living in the Nile Basin, the river is their life:. This 6,825 km waterway, whose watershed（流域） covers three million square kilometers, flows through mountains ,woodlands, lakes and deserts. Its potential for fishing, tourism and shipping is great—but so are its challenges.
Water shortage , already serious in Egypt and Sudan , will soon influence several other countries in the watershed as well. Today, about 160 million people depend on the Nile River for their living. Within the next 25 yeas ,the district's population is expected to double, adding to the demand brought about by growth in industry and agriculture. The frequent drought（干旱）adds to the urgency.
Water quality is also a problem. Precious soil is washed out to sea. Wastes from industry and agriculture create pollution. Higher concentrations of salt influence irrigated soils. Water-borne diseases continue unchecked. In areas where it's hot and damp, water hyacinths choke off lakes, dams and other sections of the river, making it difficult for fishing and other businesses to move forward.
Native people along the narrow area of farmland have watched the sand move closer day by day. They’ve seen the river change course, and their only source（来源） of water thickened with mud. They’re very poor and have few choices.
But a new program, the Nile Basin Initiative （NBI），is offering very practical assistance. The program is more than just a water-management project. It’s a plan for the social and economic development of a vast district: it concentrates on the needs of the poorest of the poor and the environment that supports them.
These are whole ecosystem problems, calling for united solutions（解决办法）. Half the Nile Basin's countries are among the world's poorest nations；yet, somehow, they must find the resources, skills and political will to overcome these challenges.
68. What are the great challenges the Nile Basin faces？
A. The development of .shipping industry.
B. Overfishing of native people.
C. Water shortage and water quality.
D. Increasing population and tourism.
69. The underlined word “hyacinths”（in Paragraph 3） refer to “ ”.
A. animals B. plants C. rocks D. salts
70. The program NBI is mainly aimed at .
A. preventing water pollution B. changing the river course
C. improving living condition of the poor
D. preventing land from becoming desert
71. What would be the best title of this passage？
A. People's Life in Egypt and Sudan
B. Frequent Drought in Egypt and Sudan
C. The Poorest Countries in the Nile Basin
D. The Ecosystem Problems in the Nile Basin
68．C 69．B 70．C 71．D

I was small for my age. I was shy and sometimes it was hard for me to make friends with the others. However, learning came fairly easy for me. I was the best in most of my classes, but PE class was my nightmare (恶梦) and made me feel that I was not as good as the others.
Miss Forsythe was our PE teacher. She was young and energetic. Everyone liked her. She said that we all had to come to her classes. No one could hide from Miss Forsythe! One day she told me that she wanted me to play a game with another girl in a PE show. I was rather worried that I wouldn’t do a good job when she explained her idea, but she was excited. With her encouragement, I had no choice but to agree. It was a "boy meets girl" game. I played the boy and my classmate, Margaret Ann, played the girl. We were dressed in evening clothes and danced around the floor. According to Miss Forsythe, I had to pick up Margaret Ann when we finished the dance. Since I was not strong enough to pick the tallest girl up, it was she who picked me up. I suddenly felt ten feet tall! It was a huge success and everybody applauded (鼓掌) for our excellent performance. What a wonderful ending! Afterwards, I smiled confidently (自信地).
Miss Forsythe’s understanding and willingness to create a place for me in her show (which certainly did not need me) gave me some much needed confidence. She was and always will be my favorite teacher.

Most of us seem to reach our peak of alertness (警觉) around noon. Soon after that, alertness declines, and sleepiness may set in by mid-afternoon.
Your short-term memory is best during the morning—in fact, about 15 percent more efficient than at any other time of day. So, students, take notice: when you are faced with a morning exam, it really does pay to review your notes right before the test is given.
However, long-term memory is different. Afternoon is the best time for learning materials that you want to recall days, weeks or months later. Politicians, business executives or others who must learn speeches would be smart to do their memorizing during that time of day. You should try to do most of your studying in the afternoon, rather than late at night. Many students believe they memorize better while burning the midnight oil because their short-term recall is better during the early hours of the morning than in the afternoon. But short-term memory won’t help them much several days later, when they face the exam.
By contrast, we tend to do best on tasks related to the process of knowing, understanding, and learning numbers during the morning hours.
What about sports? During afternoon and early evening, you’re able to react the quickest to an outside stimulus—like a baseball speeding toward you. Studies have also shown that late in the day, when your body temperature is peaking, you will consider PE easier and less tiring—whether it actually is or not. That means you are more likely to work harder during a late afternoon or early evening workout, and therefore benefit more from it.
In fact, all of your senses—taste, sight, hearing, touch and smell—may be at their keenest during late afternoon and early evening. That could be why dinner usually tastes better to us than breakfast.
While all of us follow the same general pattern of ups and downs, the exact timing varies from person to person. It all depends on how your “biological” day is structured. Each of us can increase our knowledge about our individual rhythms. Learn how to listen to the inner beats of your body; let them set the pace of your day. You will live a healthier and happier life.

Skateboarding has become one of several non - traditional activities that PE teachers around America are introducing to inspire kids to exercise regularly. Some PE classes feature in-line (滚轮) skating, yoga, and even rock climbing. Experts have called those types of activities “the new PE”.
Such activities are part of a larger effort to help kids develop lifelong fitness habits and to keep them from becoming overweight. Now, 9 million U.S. children and teens are overweight. Obesity (肥胖) can lead to health problems such as diabetes and heart disease later in life.
“Our children and youth are becoming unhealthy and obese,” says Lindsey Johnson. “Skateboarding is a great activity that keeps kids doing physical movement and gives them new skills and interest.”
Some schools don’t allow skateboarding because they say it is dangerous. Cendali, however, argues that regular practice eliminates a great deal of the danger. “We teach students how to do it and how to do it safely,” he says.
Some people say skateboarding teaches life lessons. “Skateboarding teaches kids to believe that if they stick with something they will finally succeed,” says education expert Richard Sagor of Lewis & Clark College in Portland, Oregon.
Skateboarding inspires kids not to give up in learning difficult skills. “It’s natural for kids to want to learn and get better at things,” adds Sagor. “When it comes to skateboarding, they’ll try a trick hundreds of times before they succeed.” That same effort could be made in schoolwork.
Eric Klassen agrees that skateboarding requires kids to stop saying a task is too hard for them. “A baby will attempt to walk 600 to 900 times before he or she is successful,” says Klassen. “We tell students that they shouldn’t say ‘I can’t do it’ unless they’ve tried 600 to 900 times.”
