1、一般将来时表示在未来的某个时间将要发生的某个动作或状态。学明白一般将来时要理解的一下三个至关重要的概念： 预测,表示说话人认为将来会发生某件事。 事先计划：说话人在头脑里已经做出决定将来要做某件事。 3 意愿：说话人既不是预计某事会发生,也不是预先经过考虑决定将做某事,而是在说话的时刻立即做出决断表明他将做某事。 用来预测,表示预测,或说估计将来要发生某事,可用 will 或be going to。 According to the weather report, it will be windy tomorrow. 表示打算去.,要.时,可用be going to do。 This is j

2、ust what I am going to say.C将要、正要时,可用be about to do。 强调近期内或马上要做的事。e.g. Do not worry, I am about to make a close examination on you. 别担心,我马上就给你做一次仔细的检查。D be to do的5种用法：a按计划、安排即将发生某事或打算做某事。例：She is to be seen in the lab on Monday.星期一你准会在实验室见到她。b 该做或不该做的事情语气上接近于should, must, ought to, have to,表示一种命令、规劝

3、性语气。 e.g.：You are to go to bed and keep quiet, kids. Our guests are arriving in less than 5 minutes.孩子们,你们必须 上床睡觉,不准吵闹。我们的客人5分钟之内就要到了。c 能或不能发生的事情接近can, mayHow am I to pay such a debt?我怎么可能还得起这么大的一笔债呢？d 不可避免将要发生的事情,后来将要发生的事情。I assure you that the matter _ as quickly as possible. Have a little patienc

4、e.A. will be attended B. will be attended toC. is attended D. is attended towill be attended to关键的一点是：attend表示处理,解决时是不及物动词,必须与to连用。另外,从上下文看,事情显然尚未解决,所以应该用将来时的被动语态。答案是B。e 用于条件从句如果想,设想接近if want to,或if shouldGreater efforts to increase agricultural production must be made if food shortage _ avoided.A i

5、s to be B can be C will be D has been答案是A. is to be。全句的意思是：如果要避免食品短缺,就必须作出更大努力来增加农业产量。表预测时,我们可以用will 或be going to。但两者还存在以下两点区别： 用be going to 特别是意指根据目前的明显迹象来推断某件事将要发生。 will则只是表明说话人认为或相信某件事将要发生。 be going to 通常用来表示说话人与其所说的时间马上或在相当近的将来就要发生。而will所表示的动作发生的时间可近可远。 a. Look at those black clouds! Its going t
