[答案] B. accused.

　　[注释]accuse sb. of... 控告某人犯有......, warn sb. of 警告、告戒某人有......deprive sb. of sth.剥夺某人某事。charge sb. with murder (指控某人犯有杀人罪) 。

　　[答案] D. acquired.

　　[注释]acquired (=gain for oneself by skill or ability, by one's own efforts or behavior) (由技术、能力、努力或行为) 获得; 得到：He has acquired a good command of English language. (他已精通英语。) achieve, vt. 取得 (胜利、成功等) , 实现 (目标、目的等) 。 attain, vt.达到 (目的等) , 取得 (成就等) ：1) I hope you will attain your object. (我希望你会达到你的目的。) 2) He attained success through hard work.

　　[答案] A. actual [注释]本题中actual (=existing in fact, not imaginary) 实际使用过的。

　　actual, read, genuine 是同义词, 有时可以互换, 如：an actual (or real) event in history, (历史上的真实事件) , real (or genuine) banknotes(真钞票), 其反义词是false (假的) ; original (原来的) , 其反义词是duplicate (复制的) 。从不同的角度看, 似乎任何一个选择都说得过去,但按照题意选A. actual 最佳, 因为题中强调的不是钢琴的真假, 而是指作曲家“实际使用过的”。本题译文：这是作曲家创作他的一些杰出作品时实际使用过的那台钢琴。

　　[注释]adjust (=arrange, put in order or agreement; make suitable or convenient for use) 强调, 调节, 使适应; The body adjusts itself to change of temperature. (身体能自行调节以适应温度的变化。) My eyes have not been adjusted to dark yet. (我的眼睛还没有适应黑暗。)本句中adjust 是不及物动词。I must adjust my watch. It's slow. (我必须调一下我的表。它走得慢了。)
