句子部分的答案如下：

　　44. Will be making decisions in such areas as product development, quality control and customers’ satisfaction

　　45. To acquire new skills that will help you keep up with improved technologies and procedures

　　46. Don’t expect that the companies will provide you with clearly defined career paths

　　44题，明显是考察一些名词的写法。以product development 为例，在听写时不应逐

　　字母地进行拼写。用pt/dv的代替法自然更好些。

　　45题，能够写出To acquire new skills就应该能够得到一半的分数了。

　　46题，Don’t expect that the companies will give you career paths 就是主干。

　　整体上看，今年的听力题目的确有难度的上升。由于目前四级试卷采取标准记分，所以，即便大家觉得自己没有做对几道题目，按照整体排名来算，也许最终也不会是一个很差的结果。英文的学习是一个长久的过程，请不要因为一次考试的结果而改变了你学习英文的最终目的。
