    function kaishi(){
        setTimeout("bh()",3000);
        sum=0;
    }
//    实现地鼠出现的动作
    function bh(){
        sj=Math.floor(Math.random()*9);
        img1=document.getElementsByTagName("img");
        img1[sj].src="dishu.gif";
//        给地鼠图片添加单击事件和打击动作
        img1[sj].setAttribute("onclick","daji()");
        setTimeout("xs()",1000);
    }
//    实现打击地鼠的动作，将地鼠图片更换为击中图片，并且去掉onclick事件，避免出现一只地鼠击中两次，加两次分数的情况
    function daji(){
        img1[sj].src="shang.gif";
        img1[sj].removeAttribute("onclick");
//        更换一次图片积分器加十分
        sum+=10;
//        改变积分器
        document.getElementById("fen").innerHTML=sum/10;
        document.getElementById("fen1").innerHTML=sum;
    }
//    一秒后没击中地鼠，地鼠消失动作
    function xs(){
        img1[sj].removeAttribute("onclick");
        img1[sj].src="keng.gif";
