文章内容: This argument, of course, ignores the true nature of public communication and the nature of the occasions in which it occurs. When we engage with people we do not know well to solve problems, share understanding and perspectives, advocate viewpoints, or seek stimulation, we are engaged in public speaking. Public communication is a familiar, daily activity that occurs in the streets, in restaurants, in board rooms, courtrooms, parks, factories and meeting. Public communication is usually situation-specific and ephemeral. Most audiences do well if they remember as much as 40 per cent of what a speaker says immediately after the speaker concludes; even less is retained as time goes by. This fact is both reassuring and challenging to the public communicator. On the one hand, it suggests that there is room for human error in making public pronouncements; on the other hand, it challenges the public speaker to be as informed as possible and to strive to defeat the poor listening habits of most public audiences.
问题: Use information from the above paragraph to complete the following statements. Use NO MORE THAN THREE WORDS OR A NUMBER.
S1 The writer defines public speaking as any activity where people jointly explore problems, knowledge, attitudes and opinions, or look for _____________.
S2 At the end of most public speeches, most audiences immediately forget about _____________ of what they have just heard.
S3 Because most public speeches are short-lived, the speaker should work to counteract the _____________ of the listeners.
试题解析：在S1中空格的前面出现一连串的排比：explore problems, knowledge, attitudes and opinions, or look for...，文章中相应的出现如此的排比的地方第二到第三行：solve problems, share understanding and perspectives, advocate viewpoints, or seek stimulation, 其中solve与explore同义，understanding与knowledge同义， viewpoints与opinions同义，而seek又与look for同义，因此答案是stimulation；S2中的关键词为most audiences和forget，而在第二小段的第一到第三行有：Most audiences do well if they remember as much as 40 per cent of what a speaker says immediately after the speaker concludes，其中有关键词most audiences，以及forget的反义词remember，因此这里应填入60%；在S3中，关键词为work，counteract和listeners，此处的work有“努力、奋力”的意思，counteract表示“反抗、反对、与...作斗争”，而listeners和audiences是同义词，根据第二小段的最后两行：to strive to defeat the poor listening habits of most public audiences，我们可以得出正确答案为poor listening habits，其中strive和work同义，defeat和counteract同义。
