一道英语语法题怎么选 the project requires more labor that you()because it is extremely difficult a has been put in b have been put in c to be put in d being put in
选B,由题目可知 labor that you()because it is extremely difficult是一个由that引导的定语从句,that在从句中作宾语,即正常语序应该是have been put more labor in the project,A错了应该是have,如果you后面填C和D则不是一个完整的句子,故排除
