选择题
Dark clouds _______ the sunlight. It seemed as if it was going to rain.
A．left out
B．picked out
C．blocked out
D．put out
答案
答案：C
题目分析：考查动词短语辨析。句意：乌云遮住了太阳。看起来像要下雨了。leave out遗漏；pick out检出；block out阻挡，遮住；put out扑灭。如：We put a tarpaulin across the window to block out the sun-light. 我们将涂焦帆布横挂在窗子上遮住阳光。故选C。
