答案与解析：
r only son has never thought
本题注意表示 从未 用现在完成时来表示时态;设想做某事：think to do;独生子：only son
h your decision against its possible consequences
本题重点注意下 权衡 的表达：weigh sth. against sth;后果：consequence
d he break/breach his promise/commitment to pay back the money
本题考察部分倒装，当表示否定含义的.词或者词组放句首时(本句是under no circumstances)，后面应该用部分倒装;此外也要注意违背承诺的表达以及时态的选择。
