The steel industry has changed radically over the last two decades, as large, integrated companies such as Bethlehem Steel once conducted operations from mining at one end of the process to shipping at the other have greatly downsized, or in some cases shut down altogether.
as large, integrated companies such as Bethlehem Steel
as large, integrated companies, such as Bethlehem Steel, that
with large, integrated companies, such as Bethlehem Steel, that
while large, integrated companies, such as Bethlehem Steel, that
and large, integrated companies such as Bethlehem Steel
答案是B 想請教幾個問題:
1. as在這邊的用法,題目有三個動詞(分別是has、conducted、have),所以應該需要兩個conj,B選項有個that,所以as在這邊也是conj嗎?
The steel industry has changed radically over the last two decades, as large, integrated companies, such as Bethlehem Steel,( that once conducted operations from mining at one end of the process to shipping at the other為形容詞子句修飾Bethlehem Steel) have greatly downsized, or in some cases shut down altogether.
2. that前面可以加逗點嗎?
謝謝解惑~
