【題目】Do not sign any agreement until you ______ a lawyer or some other knowledgeable person to read it.

A.will askB.have askedC.are askingD.will have asked

【答案】B

【解析】

考查時態(tài)。句意:在沒有請律師或其他有知識的人閱讀之前,不要簽署任何協議。此處是not…until引導的時間狀語從句,主語是祈使句,則從句用現在時態(tài),排除A、D,且從句動作并不是正在進行,而是動作先于主句動作,應該用現在完成時態(tài)。故選B。
