Those sounds, whether spoken, 【B7】_______ written in letters, we call words. The power of words, then, lies in their【B8】______—the things they bring up before our minds. Words become 【B9】_______ with meaning for us by experience;【B10】______the longer we live, the more certain words【B11】______the happy and sad events of our past to us; and the more we read and【B12】______, the more the number of words that mean something to us【B13】______. Great writers are those who not only have great thoughts but also express these thoughts in words which appeal【B14】______to our minds and emotions. This【B15】______and telling use of words is what we call【B16】______style. Above all, the real poet is a master of【B17】______.

【答案解析】解析：本句意为“之后他们(赞成)______一些符号”。agree可以与介词to，with，on(upon) 搭配。这里句意是“人们商定了一些特定的符号”，故D项agree upon“同意”符合题意。agree to sth．“答应(某事物)”其后通常为表示“计划”“建议”的词，agree with sb．“与某人意见一致”和 agree in“在……方面意见一致”均不符合题意。
【答案解析】解析：本句意为“我们的阅读和______越丰富，对我们来说有意义的词语数量也______”。空格处所填词应与read构成并列关系。think“思考”，collect“收集”，learn“学习”，recite“背诵”。代入可知，只有通过阅读和学习，我们掌握的词汇才会更多，且read and learn是常用固定搭配，故C项符合题意。
【答案解析】解析：本句意为“首先，一个真正的诗人是______大师”。本题考查固定搭配，master of“精通……的能手”，通过下文He can convey his meaning in words…，可知B项words正确。A项signs“符号：手势”、C项style“风格，类型”和D项sound“声音”均不符合题意。
