Neworiental SC book P229 No.207[原创]
Geologists believe that the Bering land brighe, over which human beiings( are thought to have first entered) the Americas, disappeared about 14,000 years ago when massive glaciers melted and caused the sea level to rise several hundredes feet worldwide.
E.Were thought to first enter为什么不对?
我认为1)人通过白令海峡是过去的事情,应该使用一般过去时。
2)be thought to 后的动词形势没有用现在完成时的必要。
请大牛们指点。[em06][em18][em20] |
