【正确答案】 C

【答案解析】[解析] bound意为“肯定的，很可能的”，be bound to do sth.意为“很有可能或肯定会做某事”，如It"s bound to rain soon(过一会儿肯定会下雨)和In a group as big as this, you are bound to get occasional disagreements.(在这么大一个组里，你肯定会不时遇到不同意见。)故would certainly“的确，当然”正确，其他词项的意义分别为：would unnecessarily“没有必要地”，would simply“仅仅；只是”，would alternatively“两者择一”意义均与其不符。
