Bill was a very good pilot. He had been in the air force for several years, and had been very successful. Now he was sent to a small field in the middle of a forest,  1  planes were able to attack the enemy very easily,  2  it was near the front line, but  3  to find. The forest trees were very tall and very  4  on all sides, so planes had to go down very quickly and then stop their falling very  5  before they   6   on the ground. Only the  7  pilots were able to land safely, and even some of those lost their planes and  8  because they hit the trees on the ground. After Bil《清平乐》赏析。
