四 任务型阅读 （注意：每个空格只填一个单词）
Now students’ English handwriting gets worse and worse. That makes their teachers feel worried. Is your English handwriting beautiful? If not, here are four steps that really work!
◆Use paper that has lines
Using paper that has lines can keep you writing straight 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.2·1·c·n·j·y
◆Slow down
If 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 not easy for you to stop where you should, and even worse, you may make more mistakes.www-2-1-cnjy-com
◆Hold your pencil right
When you hold your pencil the correct way, writing is much easier. Some kids press(按,压) down really hard when they write. That makes the handwriting not nice. Try to relax yourself 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.21·世纪*教育网
◆Draw more pictures
Drawing can improve your handwriting. You need to use the skills to control your pencil better when you are drawing pictures. Even though you have no chance to draw at school, you can practice by yourself at home.21教育网
