89 would have survived
90 may feel lonely away from home
91 at the rate of 12 million each year原句為什么錯？89 用should 也是對的，但是考慮到后句had been 的時態(tài)，所以可用should have had a chance 90 be likely to do sth 應(yīng)該在此處也可以用這個結(jié)構(gòu)；但是不宜用outside,因為outside 常用于指戶外，建筑（如房屋等）的外面，不是“出門在外”的表達(dá)。91 通常speed 和介詞 at搭較多， at the speed ；1200萬的表達(dá)是12million, 不加s；如果要用annual的話，用副詞形式，annually供參考
