问题描述：
We spent half a year in building the park.(改为同义句) It___ __ half a year ___ ___ the park.
答
took to build
答
改为“It took us half a year to build the park."
原句意思为：我们花了半年时间建这个公园。spend 用了其过去时，表明花了多少时间在某事上。
这句话就等同于it 引导的句型”It takes sb some time to do sth"(做某事花费某人多少时间）。这是一个固定句型，记住就行了。既然在原句中spend 用了其过去时，那么在转换成同义句的时候，take也要换成过去时。
答
took us to build
答
It_took__ _us _ half a year _to__ _build__ the park.
答
是这样的：We spent half a year in building the park 这个句子里中用了句型：sb spend some time (in) doing sth. 这个句型的同义句是： it take sb some time to do sth 花费某人多少时间去做某事.it是形式主语；其真正主语是动词不定式“to do sth”.所以应该是：It took us half a year to build the park
