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 doesnt 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_AThe person you are speaking to will understand you and make allowances for any mistakes he hears.BThey may try to avoid making similar mistakes next time.CObviously the better answer is to expand their vocabulary.DIf you have this proactive outlook，then you will see English opportunities wherever you go.EHowever, their spoken English does not have to remain“poor”！FSecond，they are afraid of making mistakes.GThe second reason lies in the reluctance of using what has just been learned.答案：15ECFAD第四节：短文改错 假定英语课上老师要求同桌之间交换修改作文，请你修改你同桌写的以下作文。文中共有10处语言错误，每句中最多有两处。每处错误仅涉及一个单词的增加、删除或修改。增加：在缺词处加一个漏字符号()，并在其下面写出该加的词。删除：把多余的词用斜线()划掉。修改：在错的词下划一横线，并在该词下面写出修改后的词。注意：1.每处错误及其修改均仅限一词；2只允许修改10处，多者(从第11处起)不计分。Today is Sunday.
