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?
New equipment and other improvements reduced the amount of time-from eleven hours in 1982 to six in 1988- workers needed to produce a ton of steel.
time-from eleven hours in 1982 to six in 1988- 后面- - 之间的是一个插入,解释TIME
看主干:New equipment and other improvements reduced the amount of time workers needed to produce a ton of steel.
补充完整应该是 time that workers needed to produce a ton of steel. ^^ lz明白了么~
