  • 第1题:

    The boy( )when he said that he ( )the eggs( )by the hen in the closet before he( )down to have a rest。

    A.was lying,had laid,laid,lay
    B.had laid,lay,laid,was lying
    C.lay,was lying,lain, lay
    D.laid,lay,lain,lies

    答案:A
    解析:
    题目意为“当那男孩说在他躺下来休息之前把母鸡下的蛋放到柜子里去了时,他在撒谎。”lie意为“说谎,躺”,过去式为lied,过去分词为lied,现在分词为lying;lay意为“放,下蛋”,为及物动词,过去式为laid,过去分词为laid,现在分词为laying。其中,lie down为固定搭配,意为“躺下”,根据题干中“said”确定要选择过去时态,为lay down,可以排除选项B和D,且before引导的句子中,主句用过去完成时,从句用一般现在时,因此he()the eggs应当是过去完成时态,为had laid,故选项A正确。
