Question

请教一个句子的语法问题.
my experiment in what the Americans term “downshifting” has turned my tired excuse into an absolute reality
in what the Americans term这个不明白,

Answer 1

My experiment是主语
in what the Americans term “downshifting” 是my experiment的定语.
has turned是My experiment的谓语
my tired excuse into an absolute reality是主句的宾语.
在定语in what the Americans term “downshifting“,the Americans是主语,term (称为,叫做）是谓语.downshifting 是宾语.
全句意思为：我那个被美国人叫做”下漂“的实验将我的陈腐的借口变为绝对的现实.
downshifting；暂时译为下漂或下移,可根据实验的具体内容来确定.
