老师您好.
有一句话：left,until now,to odd,low-level IT staff to put right,and seen as a concern only of data-rich industries such as banking,telecoms and air travel,information protection is now high on the boss's agenda in businesses of every variety.
它先说直到现在until now,意思是直到现在还怎么样,最后又说 现在now high on...,也是说现在怎么样,这两句话都说的是现在,而情况却不同.为什么呢,怎么理解呢?如果要表达原来怎么样,现在的情况变了,变得怎么样了,一开始也不应该用until now啊,用意思是“直到不久前”的词语表达不是更明确吗?
不能理解.但是句子表达应该没错,因为是考试试卷上的.
