“boost”可以作动词也可以作可数名词，意思是“增强、促进、刺激”。我们前不久学习了它的动词用法，今天来掌握它的名词用法。英英释义: something that gives someone more confidence, or that helps something increase, improve, or become successful。它的动词用法相比，boost 作名词在外媒中出现的频率要低一些，不过还是值得掌握。boost 前面一般接动词 get, receive, give, provide 等动词，后面一般接 to 和 for 这两个介词，后面接的常见名词有 economy, sales, confidence, morale, productivity 等。
例句:
① 新的港口建成后无疑可以促进当地经济的发展，除了可以说： The new port will undoubtedly boost local economy.
1) The new port will undoubtedly be a boost to local economy. 2) The new port will undoubtedly give local economy a boost. 3) The new port will undoubtedly provide local economy with a boost.
② 同样，利物浦在连续输掉 3 场比赛后终于在主场赢得了比赛，极大地鼓舞了球队的士气，除了可以说：
After losing three matches in a row, Liverpool finally won a game at home, greatly boosting the team's morale/confidence. 还可以说： After losing three matches in a row, Liverpool finally won a game at home, which provides a much-needed morale boost for the team.
"much-needed"这个形容词表达出了这种 boost 的迫切性和重要性，可以顺便掌握。
1）翻译：
