3、 _ (go) there.10If I should see him tomorrow，I _ (invite) him home.一、will和be going to 用法比较1两者都可以表示预测将要发生的事。be going to强调从目前的证据或迹象表明可能发生某事；而will则表示依据直觉、知识、经验等做出的揣测。I told you to come early.Youre going to have trouble.我告诉过你要早来。你要有麻烦了。There will be a day when all computers in the world break down.将来有一天

6、 your shoes cleaned.如果打算今天下午打网球，你最好把鞋擦好。If he will listen to me，Ill give him some advice.如果他乐意听我的，我就会给他提些建议。If he wont come，well ask someone else.如果他不愿来，我们就问别的人。二、虚拟语气在非真实条件句中的用法虚拟条件句主句例句与现在事实相反的假设一般过去时(be用were)should/would/could/might 动词原形If I were you，I should seize the chance to go abroad.与过去事实相反

15、uld/should/might be2(should) leave3.knew4(should) go5.would have scored6wouldnt have made7.would win8hadnt been caught9.hadnt gone10would invite课堂活动区感悟高考1D句意为：你错过了关于核污染的讲座真是遗憾。我本想去听的，但我忙着准备工作面试。由语境可知，此处表示“本想去而事实上没去”，为虚拟语气。叙述与过去事实相反的情况要用would have done，故D项正确。2D句意为：天气又热又干燥。是的。要是稍微下点儿雨，现在的情况就会更好一些！那样我的

16、蔬菜就不会死掉了。由条件句中的had rained可以推出这是与过去事实相反的虚拟语气，但是主句有时间状语now，所以用了与现在事实相反的虚拟语气would be；最后一句话也是与过去事实相反的虚拟语气，故用wouldnt have died。3A句意为：如果我知道这个电脑程序，就会节省大量的时间和精力。由上句“Had I known”可知，从句为与过去事实相反的虚拟条件句，省略了if。那么主句谓语形式应为would have done。4Bshould表示“假如，万一”。如：If you should need any help，heres my number.万一你需要帮助的话，这是我的电话号码。5D句意为：要是没有他们的帮助，我们不可能及时完成那个计划。but for要是没有，句子应用虚拟语气。又因计划已经完成了，所以用“情态动词现在完成时态”表示对过去发生的事情的猜测。6D在听完第一个说话者的话之后“我不知道Ann在住院”这个情况就已经成为过去，所以要用一般过去时，因此可以排除B、C两项；我去看她这个动作发生在将来，是临时决定要去做某事，没有计划和安排性，所以用will，不用be going to结构，由此可以排除A项。故此题应该选D项。对点训练1A2.D3.A4.A5.A4
