by the end of the decade 要用将来时 is错
cost to meet regulation错误,cost to 后加成本的对象,to do 表目的时只能用在抽象名词之后,如way,effort ,goal等; 时间状语为by the end of ,主句时态应用将来时。
end of the year 擺在最後 這個句子要用過去式
: "US industry's cost"改为 "the cost to the industry..."; "the cost IS projected at 10%.... by the end of the decade", 用将来时 ",by the end of the decade the cost WILL be 10% of the price per barrel".
projected at 用法错误
可以先注目动词,一个是estimate,一个是project,明显是E更好,按照动词先杀。
projected at wrong idiom
cost to接收费的对象,cost of 接收费的原因
A, C的by the end of the decade修饰 is projected 和 is estimated。句意完全不通。
Moreover, "the cost IS projected at 10%.... by the end of the decade", here IS-wrong, future tense must be used. The idea is that "by the end of the decade, the cost WILL be 10% of the price per barrel".
A, C的by the end of the decade修饰 is projected 和 is estimated。句意完全不通。
