1. A.
   to issue
2. B.
   being issued
3. C.
   to have issued
4. D.
   to be issued

Answer 1

A
解析：
本題考查不定式作主語(yǔ)補(bǔ)足語(yǔ)的用法及非謂語(yǔ)動(dòng)詞的時(shí)態(tài)和語(yǔ)態(tài)。order sb．to do sth．命令某人做某事句中的order是以被動(dòng)形式出現(xiàn)的，故其后應(yīng)接不定式作主語(yǔ)補(bǔ)足語(yǔ)。又因issue（發(fā)布）的賓語(yǔ)是clear warnings，且該動(dòng)作尚未發(fā)生，故選不定式的一般式作主補(bǔ)。
