以下是引用番茄笑了在2005-7-5 11:00:00的发言:D. sloth, found in Puerto Rico in 1991, have been dated at 34 million years old, making the sloth the earliest known mammal on 看完题目以后,觉得好像每个选项都有问题,不知道选哪一个好!看了大家的讨论,结果是d。我有一些问题希望大家能指教指教。 1 为什么这里要用现在完成时? 用过去时不是更好吗? 2 found in Puerto Rico in 1991 这个在整个句子中是做什么成份啊?sloth不可能自己找到自己肯定是别人找到它,为什么不用被动语态呢? 3 这里不是应该用the earliest known mammal of 更为合适吗?D为什么用the earliest known mammal on the Greater Antilles islands.难道是指这个岛上最早的脯如动物? 请各位高人指教啊! 如果问题太浅,还请大家见谅!

偶来试试看。8过先申明偶绝对不是nn哦!
为什么这里要用现在完成时? 用过去时不是更好吗?
偶觉得用现在完成时更好,因为考古的年代到目前为止推论为34m年,说不定以后会有了更精确的测量方法会改变这个34m年。要强调的是到目前为止。
found in Puerto Rico in 1991 这个在整个句子中是做什么成份啊?sloth不可能自己找到自己肯定是别人找到它,为什么不用被动语态呢?
定语吧?被动语态省略了。
这里不是应该用the earliest known mammal of 更为合适吗?D为什么用the earliest known mammal on the Greater Antilles islands.难道是指这个岛上最早的脯如动物?
好像animals 的话,ON the islands 听上去更顺吧。
一家之言,请各位指教!
