what size.
从回答 size six可以看出,提问是针对size的具体数值,而一个具体数字是被看作是一个整体.
比如说
10 years is a long period.
虽然主语是10years,但是它是一个整体.
而问句中使用了are,是因为它是作为shoes的谓语.

B

考查强调句型。分析题目结构可以看出,该题目考查的it 引导的强调句型。因此第二个空应填入that;第一个空应填入what,在从句作meant的宾语。全句大意:不仅是因为晚会的规模,而且是因为晚会对于我们无奈公司的意义使得它独一无二。

have...on的意思是穿着,是个表示状态的,已经穿在脚上了.可是现在这个对话谈论的鞋明显是还没有穿上嘛.wear是个表示穿这个动作最广义的词,在这个语境下面用这个词最合适了,穿衣、穿鞋,你穿多大号的?
put on是穿上.他正在穿鞋He is putting on the shoes.
dress 有点盛装打扮的意思.
