She thought he looked hungry and brought him a large glass of milk. He drank it slowly and then asked, "How much do I pay?" "You needn't do that," she said. "Mother has taught me to be kind."Years later, the young woman became seriously ill. She was sent to a big city. When Dr.Howard Kelly, a very famous doctor now, heard the name of the town she came from, a strange light filled his eyes. At once, he got up and went down through the hospital hall into her room. He made her out at once and decided to do his best to save her life. He did it and they won at last!Before she left, the bill (账单) was sent to her. She was quite afraid to open it. Finally, she looked, and to her surprise, she found these words on the bill: "Paid with a glass of milk. Dr. Howard Kelly.〞Tears of joy came down from her eyes as she said silently, "Thank you, God. Your love has passed through hearts and hands."71. Why did the boy just ask for some water?A. He changed his idea.B. He didn't need a meal.C. He was quite thirsty then.D.

That makes their teachers feel worried. Is your English handwriting beautiful? If not, here are four steps that really work!◆Use paper with linesUsing paper with lines can keep you writing straight instead of up or down when you write English words or sentences. Those lines on the paper can help you to write words in the right size. Be sure to fill the lined space completely. And make sure those capital letters(大写字母) are written properly.◆Slow downIf your writing is hard to read, try slowing down a little. For some kids, going slower makes the handwriting clear. If you write too fast, it's hard for you to stop where you should, and even worse, you may make more mistakes.◆Hold your pencil rightWhen you hold your pencil the correct way, writing is much easier. Some kids press down really hard when they write. That makes the handwriting not nice. Try to be relaxed and don't hold the pencil so hard. Let your writing appear nice and clean. If you do so, people will guess you are a student with a good habit.◆Draw more picturesDrawing can improve your handwriting. ____________________________________________.Even though you have no chance to draw at school, you can practice by yourself at home.Handwriting is very important. Imagine you are a world -famous movie star or a well -known sports player, what do you do when your fans run up to you? Give them your autographs(亲笔签名), of course!76 -77简略答复下列问题;78.将文中划线句子翻译成汉语. 79.选择适当的句子复原到文中空白处(把所选答案的字母标号填在题前括号内即可);80.判断正误(正确的填写T, 错误的填写F )76.What kind of paper can help you write well when you start learning to write English?__________________________________________________77. What should you do if your handwriting is hard to read?_______________________________________79. A. You need to use paper with lines when you are drawing pictures.B. You need to use the skills to control(控制) your pencil better when you are drawing pictures.C. You need to hold your pencil hard when you are drawing pictures.80.
