      Horror gripped (紧握) the heart of the World War I soldier as he saw his lifelong friend fall in battle.

Caught in a trench with continuous gunfire whizzing (子弹等在空中掠过的声音) over his head, the soldier

asked his lieutenant (陆军中尉), if he might go out into the"No Man's Land"between the trenches to bring

his fallen comrade back.

     "You can go," said the lieutenant, "but I don't think it will be worth it. Your friend is probably dead and

you may throw your own life away."The lieutenant's words didn't matter, and the soldier went anyway.

     Miraculously he managed to reach his friend, hoisted (扯起) him onto his shoulder, and brought him

back to their company's trench. As the two of them tumbled in together to the bottom of the trench, the

officer checked the wounded soldier, then looked kindly at his friend. "I told you it wouldn't be worth it, "

he said. "Your friend is dead, and you are mortally wounded."

     "It was worth it, though, sir," the soldier said.

     "How do you mean'worth it?'"responded the lieutenant. "Your friend is dead!"

     "Yes sir," the private answered."But it was worth it because when I got to him, he was still alive, and I

had the satisfaction of hearing him say,'Jim, I knew you'd come.'"

     Many a time in life, whether a thing is worth doing or not really depends on how you look at it. Take up

all your courage and do something your heart tells you to do so that you may not regret not doing it later in

life.

2. The underlined word "Miraculously" can be replaced by _____.

B. Because the soldier successfully brought his friend back.

C. Because what he did will bring him great honor and make him get promoted in his later life.

D. Because his friend was still alive when he reached him and he didn't make his friend disappointed.
