题目内容
9.These brightly colored bicycles can be seen everywhere.Theyare locked(lock) by the user after riding,and then unlocked by the next rider with a mobile phone.分析 这些色彩鲜艳的自行车随处可见,骑行后被用户锁定,然后由下一个骑手用手机解锁.
解答 答案:are locked 分析句子得知,主语they指的是bicycles,根据后文unlocked by the next rider with a mobile phone被下一个骑手用手机解锁,主语是动作的承受者,因此是被动语态,结合前文时态can be seen,故这里用一般现在时的被动语态,主语they是复数,故用are locked.
