问题 The young scientists got the first-hand information they needed in the scientific research____________(通过实地考察).

选项

答案 by carrying out observations on the spot

解析 本题语法点考查介词by引导的词组作方式状语的用法,注意“实地”的表达法是on the spot。carry out有两个意思(1)实现,实行,此句为该意。(2)把……进行到底,完成,例句:They decide to carry out the great cause regardless of losing their lives. (他们决定将这项伟大的事业进行到底,就算失去生命也再所不惜。)
