1、英语 科学案 序号 5&6 高三 年级 11,12 班 教师 李纯荣 学生 动词的时态和语态（2）Step 1 默写以下时态的构成形式一般现在时一般过去时现在进行时过去进行时将来进行时一般将来时过去将来时现在完成时过去完成时现在完成进行时Step 2 语法填空中的答题技巧技巧 熟练掌握常见的固定句型在一些固定句型中，对谓语动词的时态有特别的规定，我们可以把这作为判断时态的一个依据。如下面的常见句型：This/ It/ That is the first/second/last time + that。如主句中动词用is，则that从句中动词用现在完成时；如主句中动词用was，则that从句动词

2、用过去完成时。This is the first time I _ (visit) China.It was the first time I _ (have) visitors since Id moved to London.主句+ since + 从句。在该句型中，主句常用现在完成时（若主句主语是it或表示时间的词时，还可用一般现在时），since从句常用一般过去时。Cathy _ (not phone) since she _ (go) to Berlin.It _ (be) three years since I _ (join) the army.It is (high) time

3、 that。在that从句中常用动词过去时或should do。Its time that we _ (go) to school.It + be before。这种结构意为“要时间才”或“在时间以后才”。若be动词用一般过去时，则before从句中常用一般过去时；若be动词用将来时，则before从句中常用一般现在时。It will be a long time before we _ (meet) again.It was half a year before I _ (hear) from him.hardly/scarcely when; no sooner than。在这两个句型中，

4、when从句和than从句中常用一般过去时，主句常用过去完成时。意为“一就”。No sooner _ I _ (leave) than he _ (come).was/were about to do when。在when从句中常用一般过去时。I was about to leave when he _ (come).技巧 利用试题中提供的时间状语确定时态技巧 利用上下文语境推测时态很多试题中没有时间状语，但是我们可以从试题所提供的语言环境或上下文来推测出动作发生的时间或从双方的交谈中“捕捉”到时间点，这就要求有宏观把握句子和分析句子的能力。技巧 利用时态的呼应来把握时态若主句是一般过去时，宾

5、语从句的时态常与过去相关的时态（表客观事实、科学真理的从句总用一般现在时）；若主句是现在时或将来时，宾语从句的时态不受主句的限制，可根据需要选用时态。在时间、条件、让步等状语从句中，若主句为一般将来时，从句往往用一般现在时表将来，或主句为过去时，则从句也用相对应的过去时。I think he is ill today. 我认为他今天病了。You will fail the test if you dont work hard. 如果你学习不努力，你考试会不及格。He said that he had helped Tom. 他说他已经帮过汤姆了。Step 3 Practice （1）Wind-
