Charlie and his family don't always live in their house. Sometimes they live in a houseboat. There are 4 rooms in the bottom of the boat. One of them is his parents' bedroom. Another one is his bedroom. Then there is a kitchen and a bathroom. Charlie's bedroom is small, but he likes it very much. It has a small window. He doesn't open it because it's under the water. When the boat is in the water, Charlie can look out of his window and see many fish under the water. Once he saw an old car under the water. He thought it was funny to see the fish swim through the car windows.

    In the school year, Charlie's family keep their boat on the bank (岸) of the lake. In summer Charlie and his family often take their boat out to the middle of the lake. They stay on the lake for a few weeks. Then they go fishing for their food. Charlie's mother grows vegetables in pots on the boat, so they also have vegetables to eat. When it is very hot, they jump into the water and go swimming. Charlie thinks a houseboat is the best place to live in.

    Sudha Chandran, a classical dancer from India, had to have herright leg cut after an accident. She was also cut off on her career (事业) road.

    Though the accident brought her bright career to a stop, shedidn't1. In the painful months, Sudha met a doctorwho had a(n)2 onher leg. So eagerly she wanted to go back to dancing after she had been fitted witha man-made leg. Sudha believed in herself and thought she could realize her dream,so she3 onher brave journey back to the world of dancing.

    After every public performance, she might ask her dad aboutit. "You still have a long way to go!" That was the4 she used to get from her father. In January 1984,Sudha made a historic comeback5giving a public performance in Bombay. Sheperformed in such a great manner that it moved6 to tears (眼泪) and this performance pushed her to number oneposition again. That evening when she asked her dad the same question, he didn't7 anything. He just touched herfeet as a praise.

    Sudha's comeback was so8 that a film producer decided to make the storyinto a hit film. It has moved more and more people.

    People wondered9 Sudhacould manage to dance again. When she was asked the question, she would just answerquite10 ,"YOUDON'T NEED FEET TO DANCE." Where there is a will, there is a way.

If you are writing or studying, it makes very much difference where the light comes from. People who use books and pens every day have to be especially careful about the way the light shines on their work.

Every house gets its light either from daylight through the windows—which is the very best to use—or from lamps or electricity (电器); but whichever kind of light it is, the way it shines towards our books or work is a matter of great importance to the eyes.

Take a book, sit with your back towards the window, and try to read. Your shadow (影子) falls all over the page and makes it almost as bad for your eyes as if you were in a dark room.

Now turn around and face the window. The page is in the shadow again, while the bright light is in your eyes.

Try sitting with your right side towards the window. This is very good for reading, but if you were writing, the shadow of your hand would fall across the page and bother (烦扰) you a little.

There is just one other way: sit with your left side to the window. Now everything is good for reading and for writing, too.

Whatever kind of light is in the room, the rule about the right to sit is always the same.

In the middle of a cold night, I heard a loud sound outside. I 1 and looked out through the bedroom window. There was a little dog outside the door. It was 2 and shaking. The dog was black, so at first it was difficult to see at night. The yellow spots(斑点) on its eyes helped me 3 it. It was trying to get inside a box to get away from the cold air outside.

 Seeing the poor animal, I felt really 4 . I went near the little dog and wiped(擦) it till it was dry. Then I took it inside and made a(n) 5 for it with an old scarf and a small pillow. The dog seemed very comfortable in its new be d and went to 6 quickly.

 The next morning, I asked my parents if we could 7 it. They thought for quite a while and 8 . We named him Spotty. Soon Spotty became part of the 9 . Days passed on and he could take care of the house when we were out.

 Almost a year later, one midnight we heard Spotty barking(吠). We came out but saw nothing 10 outside. The next morning, I woke up and couldn't find Spotty. I searched for him everywhere, but he was nowhere to be seen. We waited for one long week. But we still couldn't find him.

In 1944, a young man carrying a bag filled with books knocked on the doors of Mr. Wu Dayou's house in Kunming. {#blank#}1{#/blank#} young man was there to ask Wu to let him study in the then National Southwest Associated University (NSAU/Xinan Lianda) , where Wu was a professor. {#blank#}2{#/blank#} (surprising) , just 13 years later, the seemingly common young man won the Nobel Prize in Physics. This man is none other than Mr. Tsung-Dao Lee.

During his years spent in NSAU, Lee quickly grew intellectually. He often {#blank#}3{#/blank#} (find) himself asking Wu after lessons for more work and would often search for {#blank#}4{#/blank#} (know) outside of the courses. 

Lee entered the University of Chicago's Graduate School {#blank#}5{#/blank#} just 23 years old and began researching physics. In 1956, he became {#blank#}6{#/blank#} (young) full professor at Columbia University. One year later, he, along with Chen Ning Yang, won the Nobel Prize in Physics. 

When Lee returned to China in the spring of 1979, he {#blank#}7{#/blank#} (invite) to teach two classes at the University of Science and Technology of China. He badly wanted more Chinese researchers {#blank#}8{#/blank#} (understand) the progress the world has made in the past decades. {#blank#}9{#/blank#} he established the CUSPEA program in 1979, which supported 915 Chinese students to study in the U. S. 

Although he was living abroad. Lee remained connected to China. His legacy serves as an inspiration (激励) for future generations to pursue {#blank#}10{#/blank#} (they) dreams and make a positive difference to the world. 

 Have you ever experienced the feeling of falling as you start to fall asleep? Sometimes you may wake up to this feeling. If so, don't worry. Many people have felt the same thing.

 In fact, the muscle twitches(肌肉抽搐) in the arms, legs or other parts of the body are called hypnic jerk(入睡抽动) or sleep starts. And they are very common. Up to 70 percent of people experience them sometimes, Huffing to Post reported. But what causes it?

 There are some theories(理论). Some scientists believe that the feeling of falling comes from the body relaxing itself, especially if the person is anxious or unable to get comfortable. As you' re going to sleep, your muscles become relaxed. But your brain stays awake. It misunderstands the relaxing of your muscles as a sign that you' re falling. The brain then jerks the body awake as if it's trying to protect you.

 Other scientists believe that different phase(时期) of sleep might cause hypnic jerks. When we sleep, we experience two phases: non-rapid eye movement(NREM,非快速眼动睡眠期) and rapid eye, movement(REM,快速眼动睡眠期). During REM, our heart rate can act irregularly. If the body experiences flashes(一瞬间) of REM while entering sleep, these irregularities could cause twitches.

 If you don't want to experience hypnic jerks, scientists have some suggestions. When you become deeply relaxed, you can learn how to reconnect your body with your brain slowly by moving your fingers and toes a little bit. Then start to move your head and open your eyes so that you can avoid the muscle twitches.

 But experts agree that hypnic jerks, though sometimes scary, are harmless. If it wakes you up, simply roll over and go back to sleep, But keep in mind: a caffeinated drink, exciting evening activities or stress may make hypnic jerks happen more often.
