　　Ⅱ.阅读理解

　　A

　　There was room for all of us，and sleeping bags kept the night chill away.We would listen to the sound of the river，and hear the coyotes(丛林狼) howling along the hills not far away.

　　Those were the cool summer nights of the mid nineties in Southern Alberta，Canada，when the four children were young and we would lie on the trampoline(蹦床) in the backyard late at night，for the sun would not set till late in July and August.We would look at the stars up above.It was a simple painting of little white dots on a black canvas，but we would never grow tired of looking at it.As our eyes surveyed that starry wonder we would see streaks of lights as meteors(流星) hit the atmosphere and burn up，or we would follow the meteors'steady path across the sky till it would also disappear.
