解题思路：简介大过程
解题过程：
1.There are ______on the desk
A.two box of pencilsB.two boxes of pencilC.two boxes of pencilsD.two boxes pencil
此题应选择C, 首先我们已知短语：a box of … 一盒……，那么“两盒……”就用two boxes of ，又因为pencil是可数名词，所以需用复数，加s。
2.Can I help you? ---yes,i'd like ______for my twin daughters
A.two pair of shoesB.two pairs of shoesC.two pair of shoesD.ywo pairs ofshoes
此题应选择B,与上题类似，“两双鞋”用two pairs of shoes
3."Two hours_____enough for mr. I can finishthe work."he said
A.are B.were C.is D.was
此题应选择C，Two hours意思是“两小时”，表示一个整体，所以动词用is。除此之外，类似的还有表示距离的短语，如：Five kilometres is a long way.
最终答案：略
