1、第一个open是一个动词,是说早上八点开门营业,用单数第三人称形式,而第二个open是形容词,表示开门营业的,所以用系表结构表示状态,他一天十个小时是开门营业的.
2、这是个比较级的问题,多音节的词要在前面加more 或less表示比较,所以CD排除,然后比较用than,所以选b

1.因为不是指的某一天，而是说的每一天；
2。比较级要用more than， less than ，因此acd都错了

1. 因为商店早上8点开门是每天都做的事情，用一般现在时，而open也是形容词，所以第二空格可以使用is open.
2. 词组搭配：less ... than 或more than

1、开店是瞬间年动作，要用瞬间动词open，而店铺在白天是一直开着的，是个持续性动作，要用be open表示“开着的”这种状态；
2、第一个选择应该是more than的搭配猜对，第三个少了more，第四个应该是as difficult as才对，只有less difficult than的语法形式是对的...

做不及物动词的open有begin, become open的“开始”的意思。The meeting opened with an interesting s...

更何况B选项的第二个空动词open没有任何时态，肯定不对嘛。

第1题,"商店早8点开门"是个长期存在的状态,应用一般现在时,用三单形式.第二个空如果选B选项,应该用三单啊,所以无论是用排除法还是正向思维都选A.
第2题是固定形式,形容词比较级+than,又因为difficult是多音节,所以要用less或more来修饰以形成形容词比较级,详细你可参考http://zhidao.baidu.com/question/201300426.html?si=...
