8、elow freezing and the days are fine, that the rocks may“sail”，the researchers said. On those occasions, the cold night air leaves a sheet(薄片)of ice only an eighth of an inch thick.

13、 strong winds.CThey are mainly pushed by winddriven ice.DThey move very slowly on smooth ice sheets.C细节理解题。根据第四段中的“Driven by light winds，the sheets push up against rocks”可知，两位科学家认为，石头周围形成的冰在风的作用下使得石头移动。4What does the underlined word “episodic” in the last paragraph probably mean?AAmazingly big.BExtr
14、emely slow.CHappening sometimes.DGoing on without stopping.C词义猜测题。由最后一段可知，能够让石头移动的条件非常特殊，很少出现，所以可推断episodic应该是“偶尔发生”的意思。BMary and Peter were having a picnic with some friends near a river when Mary noticed an object overhead.“Look！”she shouted to her friends.“Thats a spaceship up there and its going
