阅读表达。

        How can you think in English?(1)I think the best way is to practice as what a             player            every day. During the practice the football player will pass the ball to his teammates over and over again. So he won't

have to think about passing the ball in the game, he will just do it.

        (2)You can train yourself to think in English in this way. The first step is to think of the words that you use

daily, simple everyday words like book, shoe or tree. For example, whenever you see a "book", you should think

of it in English instead of in your mother language.

        After you have learned to think of several words in English, then move on to the next step —think of

sentences in English. (3) 听是学英语的一个非常有用的方法。Listen first and don't care too much about

whether you fully understand what you're hearing. Try to repeat (重复) what you hear. The more you listen,

the more you learn. After you reach a higher level, start having conversations with yourself in English. This

will lead you to think in English. 

1、在(1)句的空白处填入适当的词使句意完整、上下文通顺:                ,                   

2、将(2)句译成中文:                                                                                               

3、将(3)句译成英文:                                                                                               

4、在文中找出与下面句子意思相近的句子,并写在横线上:No matter when you see a "book", you

     shouldn't think in your native language except in English.

                                                                                                                                                    

5、找出文中或写出最能表达该短文主题的句子:
