阅读下面短文，并根据文章后的要求答题（请注意问题后的词数要求）。
(1) Although many Chinese students say they have a good knowledge of English grammar, most would admit(承认) that their spoken English is poor. Whenever I speak to Chinese students, they always say, “My spoken English is poor.” However, their spoken English does not have to remain poor! I would suggest that there may be some reasons for their problems with spoken English.
(2) First, they can’t find suitable words to express themselves because of limited vocabulary. Clearly the better answer is to expand(扩展) their vocabulary. However, you can speak with a limited vocabulary if your attitude is positive. Others will follow you as long as you use the words that you know.
(3) Second, they are afraid of . Sometimes they make mistakes when they are speaking because they are shy and nervous. Yet students should remember that their goal should be FLUENCY AND ACCURACY. You want to make yourself understood, to talk to someone in English ,as quickly and as well as you can, even if sometimes you may use a wrong word or tense, but it doesn’t matter because the person you are speaking to will understand you and ignore your mistakes.
(4) Third, no enough attention is paid to listening. You have one mouth but two ears! All that is heard is necessary for you to start speaking.
(5) Fourth, most Chinese students are inactive rather than active language learners. Instead of actively finding opportunities to improve their spoken English, they passively wait for speaking opportunities(机会) to come to them and wonder why their spoken English always remains poor. If you have positive attitude, then you will see English opportunities wherever you go.

这个问题我还想问问老师呢

B解析题意分析：Na2CO3溶液中的氢氧根是由于碳酸根的水解造成的，即是水的电离产生的；而稀氨水中氢氧根主要是一水和氨的电离产生的，可根据溶液的pH值求出溶液中的氢离子的浓度，也就等于此溶液中水电离出来的氢氧根的浓度．
