在回答这个问题之前，请认真考虑一下。
◆ this kind of, of this kind
◇ 二者都表示“这种……”，但“this kind of＋名词”作主语时，谓语动词的数常与kind保持一致；“名词＋of this kind”作主语时，谓语动词的数常与该名词保持一致。如：
This kind of actress is easy to find but directors of this kind are scarce． 这种女演员不难找，可是这种导演却不多见。
◆ though；although；as
◇ 这三个词都可以表示“虽然”、“尽管”。though和although引导让步状语从句时，常可互换，只是although的语气更强一些。如：
Though／Although it was late，the farmers kept on harvesting the crops by the lights of the tractors．
◇ 此外，though可以用于省略句，although很少这样用though引导的从句可以部分倒装，although引导的从句不用倒装语序。如：
Though poor, he is always neatly dressed．
Poor though I am, I can afford it．
