区别用法什么的

一 此处的light是光线的意思 该意思的light为不可数名词 二 从if he had worked harder中的if和had可以看出此处应是对过去的虚拟 所以用would和过去完成式 三 这里的this is可以看出应用现在的时态 ac项均为过去时 b项为现在进行时 显然不符合 我也只能排除 如何正面解释也不知道 只知道用现在的时态 四 根据句意可知这里是用过去与现在比较 故用比较级 用worring修饰day 五 句意应为没必要做 用need 注意是need do sth 我也就只能这么解释了 希望能帮你哈

1.light是光
句意是“如果以光速行驶的话它会怎样?”
2.虚拟语气,对过去已经结束的事情假设(一般与事实相反),前半句用过去完成时,后半句要用过去将来完成时。
句意是“如果他努力工作的话,他可能就会成功了。”
3.固定用法。
句意是“这是我第一次来这里。”
4.worrying才是形容词。worry是动词。more指相当,十分,比平时要更。
句意是“他过了让人焦急的一天。”
5.need即可是情态动词,直接加not,接动词,又可以是一般动词,前面加don't再接to do

1.光.
以光的速度行进会发生什么?
2.如果他努力过,他就会成功了,状语从句都用完成时了,主句当然也是,都是假设过去已经发生的事情的.
3.this is the first...这样的句子中从句一般都用完成时.
4.他度过了更让人担忧的一天.应该有上下句是表示两者的对比(对比前一天),而不是*
5.needn't 情态动词,后接动词原形
