动力和天分哪个更重要

选E。

This was what the crew of and the people at the Houston space centre attempted. This mission was successful until re-entry, when the space shuttle disintegrated without warning. The goal was not achieved; seven astronauts tragically lost their lives. This failure does not mean thatthis tradgety was without value. It forced NASA to re-examine its contingencies. NASA was compelled to look carefully at its organization structure, independent contractors, and engineering practices.

　　1．What I am most interested in is American movies．我最感兴趣的是美国电影。
