问题描述：
the guard turned around with his eyes__and a very __look on his face.A.wide open...watchful
B.widely open...alert为什么选A不选B?
答
wide作形容词来修饰open这种状态，不是用副词，而且widely作副词是广泛的意思，说眼睛睁得大时wide既是副词又是形容词 ，alert多做后置定语
答
alert可以形容人警惕，但不能形容警惕的样子。这里需要形容look
答
wide不仅可以做形容词,也可以做副词,做副词时的意思为 充分地 完全地的意思,而widely,一般为广泛地、普遍地的意思；另外 alert 做定语时只能修饰人或动物,如 an alert man,而这里为eye,因为非人非动物,选watchful.
