89 would have survived
90 may feel lonely away from home
91 at the rate of 12 million each year原句为什么错？89 用should 也是对的，但是考虑到后句had been 的时态，所以可用should have had a chance 90 be likely to do sth 应该在此处也可以用这个结构；但是不宜用outside,因为outside 常用于指户外，建筑（如房屋等）的外面，不是“出门在外”的表达。91 通常speed 和介词 at搭较多， at the speed ；1200万的表达是12million, 不加s；如果要用annual的话，用副词形式，annually供参考
