Helen turned on her flashlight. Nothing happened. The light did not come on. There was no light. What was wrong with her flashlight? She unscrewed the top of the plastic flashlight. Helen took the two batteries out of the plastic tube. She looked at the two batteries. They were “D” batteries. They looked okay. They did not look bad. But maybe they were dead batteries. She opened a package of new batteries. She put two new “D” batteries into the plastic tube. Helen screwed the top back onto the plastic flashlight. She turned on her flashlight. The light worked!
海倫打開手電筒。什么也沒(méi)發(fā)生。燈不亮了。沒(méi)有燈光了。她的手電筒怎么了？她擰開塑料手電筒的頂端。海倫把兩節(jié)電池從塑料管里拿出來(lái)。她看看這兩節(jié)電池。它們是“D”號(hào)電池。它們看起來(lái)沒(méi)問(wèn)題。它們看起來(lái)也沒(méi)壞。但是也許它們是廢電池。她打開一包新電池。她把兩節(jié)新“D”號(hào)電池放進(jìn)塑料管里。海倫擰緊塑料手電筒的頂端。她打開手電筒。又有電了！
