1、since是现在时，注意后面是had migrated 2、since releasing要求逻辑主语和句子主语一样，就变成了their descendants了. 而不是African honeybees。作者: azhongzhong 时间: 2011-8-5 13:32
这两个我都不懂呢,1.since 是现在时的标志对吧。而不是since是现在时吧。 2、since releasing要求逻辑主语和句子主语一样，就变成了their descendants了，their descendants since releasing African honeybees 有什么不妥吗？难道是African honeybees since releasing African honeybees？
