巴西政府为刺激经济复苏降低长期贷款的利率，请看本报昨日的报道：

    Brazil’s government surprised investors by cutting the main rate for long-term corporate loans to stimulate a faltering economic recovery, but vowed Friday to keep a lid on loan subsidies with a new benchmark linked to market rates.

    In an announcement that caught markets off guard late Thursday, Brazil’s highest economic policy body, CMN, cut the TJLP long-term rate to 7 percent from 7.5 percent for the second quarter.

    报道中的keep a lid on就是“控制在现有水平”，例如：

    Economic difficulties continued and the government intervened to keep a lid on inflation.

    经济依然困难，政府干预遏制通货膨胀。
