go round in circles 瞎忙
    【講解】
    go round in circles 和 run round/around in circles都有"在原地兜圈子,毫無(wú)進(jìn)展，白忙，瞎忙”的意思;但與run circles around sb.有區(qū)別。后者指“比（某人）做得出色,輕易超過(guò)(某人)”。
    【對(duì)話】
    A:Our teacher asked us to recite the text again.
    A:我們老師又要我們背誦課文了。
    B:Do you have to remember every text?
    B:每篇課文你們都要求會(huì)背嗎？
    A:Yes. He says recitation is good for us to learn English.
    A:是的。他說(shuō)背誦對(duì)我們學(xué)習(xí)英語(yǔ)很重要。
    B:I think so. But I know many people just think that's going round in circles.
    B：我也這么看。但我知道很多人都認(rèn)為那是瞎忙乎，沒(méi)有什么用。
