问题补充:
---Thestudentssittingatthebackcan’tseetheblackboard_______.
---Whynot_______themmovealittleforward?A.clear enough, letB.enough clear, lettingC.clearly enough, letD.enough clearly, letting
答案:
C解析不能清楚的看黑板,清楚修饰动词see,要用副词clearly,enough在英文中修饰名词位置不限,修饰形容词或副词位于他们后面,故只能说clearly enough,why not表示建议,等于why don’t you,后应该跟动词原形,故只能选C。
