Valerie noticed that her daddy was going bald day by day. This worried her.

    "Daddy, every day you have less hair. Why is that?"

    Her father smiled, "Round here there's a little hair thief, and he visits my head during the night. He pulls out my hairs as many as he likes. And nobody can catch him!"

    That night, Valerie stayed awake. As soon as she heard her father's first snoring (打鼾), she took a hammer (锤子)and went into her parents' bedroom. Being afraid of the thief running away, she slowly tiptoed in. When she arrived, she began to watch her father's head carefully, hoping to catch the hair thief as soon as he appeared. Before long, she saw a shadow on her daddy's head. With all her strength, she swung the hammer down.

    Thwack! Her father yelped and jumped out of his bed. The lump (肿块) on his head was already big, and growing. He turned the light on, and saw Valerie holding her hammer in the air.

    "I nearly got him, Daddy! I thought I hit him, but it looks like he escaped!"

    Meanwhile, they woke Valerie's mother up. Seeing the lump on her husband's head, she laughed out loud. "Well, that's what happens when you tell silly stories, "she said.

    So Valerie's father had to explain to her that the hair thief didn't exist, and that going bald is something that just happens naturally to most daddies. There he sat, realizing how important it was not to tell children tall tales. And Valerie still worried about her daddy, but she did something else. She bought her daddy a very nice sleeping hat.

    Have you watched movies that take place in the future? You may have seen people travelling in lying cars or using spacecraft to explore other planets. These movies could be showing us what air and space travel will be like in the future.

    Imagine the year is 2040. Your new jetpack will take you to the store. A jetpack is something that a person straps on like a backpack. Fuel and air are burned in an engine. Then hot air is forced out of the exhaust, or the bottom of the jetpack. This thrusts (用力推)the person wearing the jetpack up into the air. A person wearing a jetpack can fly.

    There are jetpacks that have already been made. One jetpack can stay up in the air for minutes. It has a range of 30 miles.

    Most experts think that jetpacks would not be good for everyday travel. A group of scientists has started a project called myCopter. The group is studying very small aircraft and wants to know if the use of tiny aircraft could be possible in the future.

    The group is thinking about how the tiny aircraft could work. The owners of the aircraft won't be trained pilots. Experts want to build aircraft that fly together. Each aircraft could send out signals to other aircraft nearby. This will help keep the aircraft from getting too close to each other. The owner of the aircraft will choose the main direction. But the aircraft will mostly be controlled by a computer on the aircraft.

    Volcanoes can cause lots of damage. Here are a few of the worst ones in history.

    Which university is the best in the world? To answer this question, university rankings (排名) may be helpful. Recently, Times Higher Education, a London educational magazine, made a list of 100 universities with the best reputation (声誉).

    Harvard University sits on top. Massachusets Institute of Technology comes in second and Stanford University makes the top three.

    Rankings can guide you when you choose a university. But it is not the only reason. Learning about which university has the best course you want to study is also important.  In China, architectural (与建筑有关的) design is the best course in Tianjin University, which is among the best in China. Math in Zhejiang University also has a great reputation.

    Besides, selecting a university is not only an academic (学术的) choice. For those who are going to study abroad, they also need to think about if their personality will fit the campus culture. Some universities such as Stanford and Duke are proud of their "high-tech culture". Their libraries are full f advanced facilities.The University of Minsota, the US is among them. There, students and teachers work with the local community to keep their environment nice and clean. The University of Iowa is No. 1 in the US for parties.

    Are you ready to find your dream university? Remember, the early bird catches the worm.

A. China's Tsinghua Univerity and Peking Univerity are ranked 36th and 41st place.

B. Many students enjoy talking and drinking in the bar.

C. Other universities pride themselves on their "green campuses".

D. Some universities may not rank highly overall but have great courses.

E. In the US, New York University is famous for its philosophy (哲学) course.
