单选题
He accidentally found a stock of jewelry stamps when he was packing up his books.
【正确答案】
B
【答案解析】[解析] 本句意思是“整理他的藏书时,他意外地发现一套珍贵邮票”。句中accidentally意为“意外的”。by the way短语意思为“顺便”,例如,By the way,why not drop in for a drink this evening?顺便说一句,今晚到我家喝一杯怎么样?by chance意为“偶然的”,例如,I met her quite by chance.我遇见她完全是偶然的。by hand意为“用手”;by nature意为“天生地,自然地”。只有by chance意思上和accidentally最接近。
