题目内容
5.他们花了一年半时间做了这个实验.It took them oneand a half years to do this experiment..
分析 and a half years to do this experiment.
解答 答案:and a half years to do this experiment..
首先通过中英文句子的比对,可知英文句子中缺少"一年半时间做了这个实验"的表达.短语"一年半时间"的英文表达是:one and a half years,"做这个实验"是do this experiment,结合设空处前面的It took them可知本句使用的句式是:It takes sb.some time to do sth.,故答案为:and a half years to do this experiment.
点评 做这类题型,首先根据所给汉语明确句子所要考查的单词或短语的拼写,再结合相关语法知识对单词或短语做出形式上的变化.
