Question

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

Answer 1

C

试题分析：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。
