瑞幸咖啡计划今年在国内新开2500家店，在门店数量上超过星巴克。请看本报周五的报道：

Chinese coffee startup Luckin is aiming to open 2,500 new stores this year and overtake Starbucks Corp. as the largest coffee chain by number of outlets in the world’s second-biggest economy, it said Thursday.

The firm, which only officially launched its business at the start of last year, has expanded at breakneck speed, propelled by a focus on technology, delivery and heavy discounting even at the cost of mounting losses.

“What we want at the moment is scale and speed,” Luckin’s chief marketing officer, Yang Fei, told reporters Thursday at a presentation in Beijing.

报道中的at breakneck speed就是“飞快地、以快到危险的速度”。例如：

In the past few years, China’s online game industry has been growing at breakneck speed.
