New equipment and other improvements reduced the amount of time-from eleven hours in 1982 to six in 1988-needed by workers so that they could produce a ton of steel.
句子结构是什么?前面已经是完整的一句话了New equipment and other improvements reduced the amount of time;中间没有任何连词吧,后面还能是一句话?workers needed to produce?整个句子结构是怎样的?有点晕啊,没连词就出现两句句子? |
