The #oilwar is on ! Rates for #VLCCs are going up the roof... TD index up by 54%, TD3 (Arab Gulf to #China) up by 219% in 3 days according to #refinitiv shipping team (chart below)... All of it driven by floating storage. With #crude oil prices down by 36% in less than a week, obviously everybody wants to be the next #Timchenko and the famous #contango play is back in fashion ! But more interestingly, it also seems the Saudi Arabian shipping company #Bahri is chartering a large number of VLCC on top of the 42 VLCC it already owned to accommodate the crude supply increase pledge from #KSA and #Aramco.

【翻折变换（折叠问题）有关的压轴题】
本题考查的是图形的翻折变换，涉及到勾股定理，等腰三角形的判定与性质，根据题意作出辅助线，构造出等腰三角形是解答此题的关键．

考点分析：
翻折变换（折叠问题）；坐标与图形性质；探究型。
审清题意：
设E（x，y），连BE，与OB交于E，作EF⊥AB，由面积法可求得BG的长，在Rt△AEF和Rt△EFB中，由勾股定理知：AF＝AE﹣EF＝BE﹣BF，解得x的值，再求得y的值即可.
