半夏投资李蓓最近发文呼吁平准基金入市提振A股。请看本报周四的报道：

A leading Chinese macro hedge fund called on the government to set up a stabilization fund to buy stocks, lobbying for direct intervention the authorities have refrained from.

Foreign investors have kept selling despite signs of the economy stabilizing and China-U.S. relations improving, which could indicate that some big institutions have decided to gradually liquidate local holdings, Li Bei, founder of Shanghai Banxia Investment Management Center, wrote in an article posted late Tuesday on WeChat.

报道中的refrain from就是“避免”。例如：

The sign on the wall says: “Please refrain from smoking.”

墙上的标语提示“请勿吸烟”。
