explain:hold fast the dream for without them life is like a borken winged bird要考口语，写个跟文章差不多的，

A person should complete his dream quikely, because if he has no dream, he will loose the power to live.

先说一下,这里的Fast是航海术语,就是Tight的意思.
意思就是：Hold your dream tightly.Because a dreamless life will beacome a bird with broken wings.
