174 Chief Diagnostic Tool 主要診斷工具
While waiting for my car, I saw a Magic Ball on the mechanic's desk. I turned it upside down and read: “Fan belt.” I shook it again. “Battery,” it said. The mechanic walked in. “That,” he said, “is our chief diagnostic tool.”
在等著修車的時候,我在修理工的桌子上看到一個魔球。我把它倒過來放,出來的字是“風(fēng)扇皮帶”。我又把它搖一搖,出來的字是“電瓶”。這時,修理工進來了。他說:“這是我們主要的診斷工具。”
