Section F　单元语法专项——过去将来时1．定义过去将来时的基本特征，即“立足过去，着眼未来”。它表示从过去某一时间来看将要发生的某个动作或存在的状态。但这个“将来”时间绝不会延伸到“现在”，而仅限于“过去时间区域内”。由此可以看出，含有这个时态的句子常带一个表示“过去某个时间点”的状语。·Mary told me that she would go to Shanghai by plane the next day.玛丽告诉我说第二天她将要乘飞机去上海。2．基本构成►(1)would＋动词原形❶I knew very little about school, but at least it would be a change, the start of a new life.我对上学几乎完全不了解，但那至少是个变化，是新生活的开始。►(2)was/were going to＋动词原形❷No one knew when he was going to finish his homework.没有人知道他什么时候会完成作业。►(3)was/were about to＋动词原形❸He said that they were about to leave at six.他说他们将于6点离开。►(4)was/were to＋动词原形❹The building was to be completed the next month.这栋建筑将在第二个月竣工。►(5)come, go, arrive, leave, die等瞬时动词，可用过去进行时态表示过去将来。❺He was leaving the next day.他第二天要走了。3．基本用法►(1)主句为过去时，宾语从句常表示将要发生的事情。❶I felt he would protect me from Mrs Reed.我觉得他可以在里德太太面前保护我。►(2)表示过去习惯性的动作。❷During that period，he would do morning exercises every day.在那段时间，他每天做早操。►(3)表示过去情况中的“愿望”“倾向”，多用于否定句。❸No matter how difficult the work was, he would keep on doing it until he accomplished it. 不管工作有多难，他总会坚持不懈，直到把它干完。❹They knew that we would never permit such a thing. 他们知道我们绝不会允许发生这样的事。❺Even after the lecture ended, the audience would not leave. 甚至在讲座结束之后，听众仍不肯离去。►(4)过去将来时，用于虚拟语气中。❻If I were you, I would not do that. 要是我是你的话，我就不会那样做。 注意：would用于过去将来时和表示过去重复的动作时含义不同。❼He said he would raise the question at the meeting. 他说他将在会议上提出这个问题。❽When I was young，I would help my mum do housework. 小时候，我常常帮妈妈做家务。[即学即练]Ⅰ.用正确的时态完成下列句子1．The truck was late.The goods and other materials we subscribed to _________________________ (arrive) in two hours.2．He told me that the device ________ (run) as long as the button was pressed.3．They promised they ________ (do)me a favour and ensure my safety.4．They believed that reality ________ (tell) you everything.5．She thought that one day you ________ (be) sensible enough not to view it as true.would arrive/were going to arrivewould runwould dowould tellwould be6．Playing with smartphones or tablets too long __________ (harm) people's health and prevent them from concentrating on their work, he added.7．The author said he was indeed concerned about this issue and he ____________ (maintain) his argument.8．In his opinion, some electronic devices ____________(be) both rewarding and limiting.9．On the basis of this amazing figure, the authorities ___________(take) measures to encourage websites to establish privacy policies.10．The boy admitted that he ________ (be) addicted to the Internet two years before.would harmwould maintainwill/would bewill/would takehad beenⅡ.用句末所给动词的适当形式填空1．Jack ________ swimming in the river every day in summer.(go)2．I ________ with you if I have time.(go)3．We will go to the cinema if it ________ fine tomorrow.(be)4．I will tell her the news when I ________ her next week.(meet)5．When ________ you ________ the car？(buy)6．We ________ good friends since we met at school.(be)7．What ________ you ________ at five yesterday afternoon？(do)8．The bike is nice.
