的，日常的”。
45as【解析】such…as意为“这样的…如”。此空后为并列的三个分词短语，即“如”后跟的例举事项。
46refere
ce【解析】这三个分词短语意为“执行日常运算、挖掘…材料、操作再生产设备”。显然，“参考材料”最合适。
f47a
d【解析】这三个分词短语是并列的，故中间的连词只能用a
d。48promisi
g【解析】此旬意为“一家大制造公司最近采访了许多…的工程师，这些工程师都已离开这家公司。”由上下句判断，此空处填“有希望的，有前景的”最合句意。49was【解析】此空显然应是句子的谓语成分，应填动词的过去式。
50far【解析】可用于修饰“toolittle”的只能是far，意为“太少，特别少”。
