1. 这是个什么词？
词：boost
英英释义：something that gives someone more confidence, or that helps something increase, improve, or become successful
例句：The new port will undoubtedly give local economy a boost.
2. 为什么选这个词？
“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。和它的动词用法相比，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。
我们试着把“boost”作动词那一期里面的例句进行改写：
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.
还可以说：
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.
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。
3. 怎样学会使用这个词？
1）翻译下面的句子：
这笔价值 3000 万美元的投资将会促使这个创业公司发展得更好。
The investment of 30 million dollars will give the start-up a much -needed boost.
（参考翻译：The investment of 30 million dollars will give the start-up a much-needed boost.）
2）结合自己的生活、学习、工作、兴趣等，想象在什么语境下会用到这个表达。先简要描述这个场景，再造句。
例子： 市场
场景 ：Mr. Trump’s police undoubtedly provide coal and steel with a boost,men who feared that they had been marginalized in dirty, dying industries suddenly feel as if they are worth something again. In the rich world,nostalgia also offers a way to rebel against someone else’s idea of progress-to“take back control”.
