二、过去将来时的表达法1.基本表达：过去将来时用“would＋动词原形”表示。He said he would come to see me.他说他要来看我。He told me he would go to Beijing.他告诉我他将去北京。
2.其他表达：(1)was/were going to do这种结构表示准备、计划做某事，或将要发生某事。The boy was not going to do anything that evening.那天晚上这个男孩不准备做任何事。When he arrived the plane was just going to take off.飞机正要起飞时他到了。(2)was/were about to do这种结构表示“正要、即将”。His father was about to be transferred to a seaside town.他父亲正要被调往一座海滨小城。(3)was/were on the point of doing这种结构表示“正要……时”。She was on the point of leaving when we came in.我们进来时，她正要离开。
(4)was/were due to do这种结构表示“定于(某时做某事)”。Word came that the ship was due to leave at mid-night.有消息说，船定于午夜起航。(5)go，come，leave，take off等少数动词可用过去进行时表示过去将要发生的情况。A great many people were coming to watch the fireworks.有许多人要来观看焰火。She told mother that she was going to a dance with Mike.她告诉母亲，她要和迈克一起去参加一个舞会。(6)was/were to do这种结构表示曾计划做某事。The man said he was to take up the position.这个人说他要承担这个职务。
三、过去将来时与一般将来时的比较一般将来时是表示从现在看来将要发生的情况，而过去将来时则是表示从过去看来将要发生的情况。Tom says that he will never get married.汤姆说他永远不结婚。Tom said that he would never get married.汤姆说过他永远不结婚。
