周一ATP马德里公开赛首轮，赛会10号种子、塞尔维亚天王德约科维奇发挥出色，最终直落两盘以7-5和6-4击败日本名将锦织圭，成功晋级第二轮。请看本报昨日的报道：

Novak Djokovic got the type of win he needed to boost his confidence and get his game back on track.

He beat 20th-ranked Kei Nishikori 7-5, 6-4 in the first round of the Madrid Open on Monday, his highest-ranked win in 10 months.

Djokovic broke serve late in each set to get past Nishikori after nearly two hours in the Magic Box.

报道中的back on track就是“回到正轨”，就是在经历一段困难或者曲折之后又回到原来预设的路径上。例如：

She speaks about getting her life back on track, and thinks the best thing for her to do right now is to get back to work.

她说希望让生活回到正轨，并且认为目前最好的办法就是重返职场。
