2017届高考英语高频词汇举例解析（3）

　　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．

　　as表示“虽然”、“尽管”引导让步状语从句时，从句要用倒装语序，将表语、状语等置于句首。 Tired as he was, he went on working with his workmates． Child as he is, he knows a lot about the computer．注意：as引导让步状语从句时，若充当表语的名词位于句首，则该名词前面不用冠词。

　　through; over; across; into 1) The PLA man jumped ＿＿＿ the water to save the boy． 2) The highway goes under the river ＿＿＿ the tunnel． 3) There is a bridge ＿＿＿ the river． 4) The ship sailed ＿＿＿ the Atlantic． 5) The students walked ＿＿＿ the gate with Mr Liu．析: into。意为“进入；到……里”，含动作方向为由外向里之意。 through。意为“通过；穿过”，侧重于指从物体的中间穿过。 over。此处意为“（位置）横跨；在……上面”，表示动作时为“越过……”之意。 across。意为“横过；穿过”，一般指从房间、原野、海洋等一端横越到另一端或两个动作方向成十字交叉状。
