It’s easy to see how the sawfish got its name. These frightful creatures can grow to be more than 6 meters long. Their bodies are flat and winged, like underwater airplanes. And their noses are shaped like chainsaws.
Sawfish are food hunters of the sea. When a sawfish is hungry, it waves its sharp-toothed snout（口鼻部）through a group of fish. Then, it lifts its nose and uses its mouth to draw the injured victims.
Hardy（适应力强的）population of sawfish thrived in warm waters along coastlines around the world for thousands of years. Over the past 200 years, however, human actions have severely endangered sawfish. Threats include fishing nets that trap the huge animals, often by mistake.
Some people collect sawfish’s snouts as prizes: One snout recently sold for nearly $ 1,600 online. In some Asian cultures, the toothy snouts are used in ceremonies to drive evil and disease away. And sawfish are also delicious. A growing demand in Asia for the fish’s fins for a pricey soup has contributed to the fish’s loves. Compared with other fish, sawfish give birth late in life and at slow rates, which makes it hard for them to recover from overfishing.
New efforts now aim to restore sawfish population. Beginning next month, an international agreement will provide protection for all seven of the world’s sawfish species. Scientists are hoping that it’s not too late to save the sawfish.
Until 1998, “this fish had never been formally studied in the United States,” says Tonya Wiley of the Mote Marine Laboratory in Sarasota, Fla. “We didn’t know such basic things as where they live, what habitat they use, how often they breed, how many young they have — even what age sawfish are when they begin breeding.”
Through historical studies and field research, scientists have become aware of how much the fish’s numbers have decreased. Today, there may be 90 percent fewer sawfish than there used to be. Wiley estimates that only 3,000 to 6,000 sawfish remain in US waters.

       “My kids really understand solar and earth-heat energy,” says a second-grade teacher in Saugus, California. “Some of them are building solar collectors for their energy course.” These young scientists are part of City Building Educational Program (CBEP), a particular program for kindergarten through twelfth grade that uses the stages of city planning to teach basic reading, writing and math skills, and more.

        The children don’t just plan any city. They map and analyze（分析）the housing, energy, and transportation requirements of their own district and foretell its needs in 100 years. With the aid of an architect（建筑师）who visits the classroom once a week, they invent new ways to meet these needs and build models of their creations. “Designing building of the future gives children a lot of freedom,” says the teacher who developed this program. “They are able to use their own rich imagination and inventions without fear of blame, because there are no wrong answers in a future context. In fact, as the class enters the final model-building stage of the program, an elected ‘official’ and ‘planning group’ make all the design decisions for the model city, and the teacher steps back and becomes an adviser.”

        CBEP is a test of activities, games and imitations that teach the basic steps necessary for problem-solving: observing, analyzing, working out possible answers, and judging them based on the children’s own standards.

63. The Program is designed ______________.

   A. to direct kids to build solar collectors               

  B. to train young scientists for city planning

   C. to develop children’s problem-solving abilities

   D. to help young architects know more about designing

64. An architect pays a weekly visit to the classroom ____________.

   A. to find out kids’ creative ideas                          B. to discuss with the teacher

   C. to give children lectures                                          D. to help kids with their program

65. Who is the designer of the program?

   A. An official.      B. An architect.         C. A teacher.      D. A scientist.

66. The children feel free in the program because ______________.

   A. they can design future buildings themselves

   B. they have new ideas and rich imagination

   C. they are given enough time to design models

   D. they need not worry about making mistakes

Hi！Have you ever suddenly felt that someone you knew was in trouble—and was he? Have you ever dreamed something that came true later? Maybe you have ESP (超感觉知觉).

　　ESP stands for Extrasensory Perception. It may be called a sixth sense. It seems to let people know about events before they happen, or events that are happening some distance away.

　　Here's an example. A woman was ironing clothes. Suddenly she screamed, "My father is dead! I saw him sitting in the chair!" Just then, a telegram came. The woman's father died of a heart attack. He died sitting in a chair.

　　There are thousands of stories like this one on record. Scientists are studying them to find out what's behind these strange mental messages. Here's another example—one of hundreds of dreams that have come true.

　　A man dreamed he was walking along a road when a horse and carriage came by. The driver said, "There's room for one more." The man felt the driver seemed dead, so he ran away. The next day, when the man was getting on a crowded bus, the bus driver said, "There's room for one more."

　　Then the man saw that the driver's face was the same face he had seen in the dream. He wouldn't get on the bus. As the bus drove off, it crashed and burst into flames. Everyone was killed!

　　Some people say stories like these are coincidences. Others, including some scientists, say that ESP is real. From studies of ESP, we may someday learn more about the human mind.
