教学与学法: 自主学习，小组讨论 教学用具：blackboard 教学过程：

二、学生自学、教师巡导：
Preview grammar and finish the exercises 三、学生展示, 教师精导
“强调”就是使句子的某一部分比一般情况下显得更加重要。英语表达中，要强调句子的某一成分，一般可用强调句型“It is (was) +that (who) +句子的其余部分”。It在句中无意义，只起引出被强调部分的作用。被强调的部分指人时，除可用that外，还可换用who（强调宾语指人时也可用whom）。使用强调句型时，应注意以下事项：
一、去掉强调结构It is (was) ? that(who)?后，剩下的词仍能组成一个完整的句子。这是判断是不是强调句型的关键。试比较：
1. It is normal that he didn’t go home yesterday. 2. It is you and Tom that didn’t come yesterday.
二、如果强调时间、地点、原因或方式状语时，不可用when, where, why或how，而仍用that。试比较：It was because of his mother why he was late. (误),
It was because of his mother that he was late. (正)。
三、 强调句型的反意疑问句形式为：It is/was+被强调部分+that?，isn’t / wasn’t it？ 四、强调主语时，that或who后面的谓语动词的形式仍然取决于原句中的主语；be的变化只有is和was两种形式，如果要表示现在时将来时的其它各种形式时，就用It is?, 表达过去时的各种形式时，用It was?.一般要与谓语动词的时态一致。如： 1. It is I who/ that am an English teacher.
2. It is the boy who/ that speaks English best in the class. 3. It was on Sunday that he gave George this ticket. 4. It is the little girl who/ that has broken the glass. 五、强调句型和（not）??until句型的结合。
句式特征为:It is/ was until +被强调部分+that +延续动词
It is/ was not until+被强调部分+that+短暂动词
如：用强调句型对I didn’t knew the result. until he came back.中的划线部分进行强调，则变成：It was not until he came back that I knew the result. 跟踪训练：
一. 用强调句型it is/ was? that/ who强调划线部分 1. She didn’t know
