the fires was presented by Cary Colaizzi of the engineering firm Goodson, which has developed a heat-resistant grout (a thin mortar used to fill cracks and crevices), which is designed to be pumped into the coal fire to cut off the oxygen supply.
【正确答案】
A
【答案解析】解析：A项restraining意为“抑制，制止”，如As we talked，I felt ajoy I could not restrain(我们交谈时，我感到一种无法抑制的高兴情绪)。根据上下文的推断，画线词containing的意思引申为“控制，遏制”，与A项的意思相吻合，故选A。B项comprising“包含，由……组成”；C项embracing“拥抱，互相拥抱，包含”，这两项为干扰项。D项releasing“释放，解放，放弃”与画线词意思不一致。
