a huge shot in the arm是什么意思呢？ 是指日本經濟在經歷了20多年的緊縮之后會復蘇嗎？
My comments:
A shot in the arm is an American slang for taking an injection of medicine, to cure one of an illness. Or perhaps it is a narcotic injection, which gives drug users a high.
Either way, you may always safely infer that a shot in the arm means a boost, an uplifting act of encouragement.
In our example, Japan getting the nod for hosting the 2020 Olympics is considered a “huge shot in the arm”, or a great boost.
A huge boost, undoubtedly, to an economy that’s been stagnant for 20 years.

“For an economy that is desperate to snap out of 20 years of deflation this is a huge shot in the arm,” said Evan Lucas, market strategist at IG Markets in Melbourne, who estimated the price tag would fall somewhere between the $13.9 billion spent for the London 2012 games and the $43 billion on the 2008 Beijing games.
