完形填空
In learning English, one should first pay attention to listening and speaking. It is the groundwork (基础) of reading and writing. You’d better    your best to speak while you do much listening. Don’t be       of making mistakes. But be careful not to let them stop (阻止) you from improving your       . While you are doing this, a good        is to write or keep a diary, write notes or letters. Then if you can, ask some others to go through (浏览)        you have written and tell you where it is wrong. Many mistakes in your speaking will be        found when you write. Through correcting mistakes, you can do better in learning English.
If you are slow in speaking, don’t       about it. One of the helpful ways is reading, either aloud or to yourself. The important thing is to choose       interesting to read. It mustn’t be too difficult for you. When you are reading        this way, don’t stop to       the new words if you can guess their meanings when they have nothing to do with the sentences. You can do that some other time.
