1.选B,
根据题目的since可以得出是现在完成时态.再看四选项,只有B符合答案.
句意为,这个穷人从他20岁起就在挖坟墓了(现在还在挖),用了现在完成进行时态表过去到现在的持续进行的动作.
2.选B
句意为,我们开始讨论吧.a,c,d是不符合题意的,B选项的shall we意为“好吗?”
3.选C
根据句意:干冰很冷,如果你用手指触摸的话,会把你烧伤.根据后面的“会烧伤”,可得出B,C两选项,再看前面的such,和so,such通常修饰名词,而so才是修饰形容词,并与that 组成so ...that...如此...以致于...
够清楚了啦...
1.B这是一个现在完成时啦,he为第三人称,要用has
2。B,Let's.......shall we?是固定的
3.C只有so,very修饰形容词,固排除B,后为一个虚拟语气,if后用一般现在时,主语用将来时
