1."which large and fast aircraft use"表示现在时态,原句意思表示已经开始了,所以是现在完成时
2.个人认为应该是一般时,“主将重现”语法.但是没有一般时.只能是完成时,意思是“一旦你尝过威士忌,你将不想要其他的了.”
3.意思是,当他到场的时候,客人“已经”走了.而且前面还是he was disappointted 说明是过去的事.
4.后面是“till now”意思是持续到现在,所以不选join,因为join是瞬间动词,不能持续发生.所以选d.在军队中服役.不能选c,因为"be army"语法不对.
5.有现在完成时态的话,我会选现在完成时.只能用排除法,原句意思是“—他今晚没来—但是他保证过.”用过去时或者现在完成时比较恰当.a是一般现在时,c是将来时,意思不符.d句子中没有出现过过去时,所以要用也用现在完成时,不用过去完成时.
