根据短文内容,从短文后的选项中选出能填入空白处的最佳的选项。选项中有两项为多余选项。

     Although many Chinese students say that their knowledge of English grammar is good, most would

admit that their spoken English is poor. Whenever I speak to a Chinese student, they always say, "My

spoken English is poor." 1_____ I would like to suggest that there may be some reasons for their problems

with spoken English.

     First, they fail to find suitable words to express themselves due to a limited vocabulary. 2_____ However,

you can speak with a limited vocabulary, if you choose a positive attitude. Others will follow you as long

as you use the words that you know. 

     3_____ Sometimes they make mistakes when they are speaking because they are shy and nervous. Yet

students should remember that their goal should be FLUENCY NOT ACCURACY. Your aim in writing is to

be accurate following the rules for grammar and using the right words and spelling them correctly. However,

in speaking your aim is fluency. You want to get your message across, to talk to someone in English, as

quickly and as well as you can, even though sometimes you may use a wrong word or tense, but it doesn't

matter. 4_____

     The third reason is that not enough attention is paid to listening. You have one mouth but two ears! All

that hearing is necessary for you to start speaking.

     Fourth, most Chinese students are reactive rather than proactive language learners. Instead of actively

seeking out opportunities to improve their spoken English they passively wait for speaking opportunities to

come to them and wonder why their English always remains poor. 5_____

A. The person you are speaking to will understand you and make allowances for any mistakes he hears.

B. They may try to avoid making similar mistakes next time.

C. Obviously the better answer is to expand their vocabulary.

D. If you have this proactive outlook, then you will see English opportunities wherever you go.

E. However, their spoken English does not have to remain "poor"!

F. Second, they are afraid of making mistakes.

G. The second reason lies in the reluctance of using what has just been learned.
