请翻译，并解析为什么！谢谢！

A 虚拟语气，对过去的虚拟 他一定是发生意外了，否则的话，那时候应该已经到这儿了。
A 他在街道上走着，没有想买东西的打算。intention 就是意愿的意思
B be junior to 比...小几岁
be senior to 比...大几岁这是senior junior 的固定用法。那个科学家比史密斯先生小几岁。

1.He must have had an accident , or he would have been here then. = he would have surely come if he hadn't had an accident = something must have happened to him, otherwise he would have surely arrived

2. He walked in the street without the intention to buy anything .= he had no intention of buying anything

3. The scientist is several years junior to Mr. Smith.= the scientist is several years younger than mr smith = mr smith is several years his senior

1.A 虚拟语气 2.A 打算的意思，B是带有目的性的，感觉应该选A
3.B
