高一英语 Unit 2 Healthy Eating (2) 人教实验版【本讲教育信息】一. 教学内容： Unit 2 Healthy Eating (2) 1. 语法：情态动词：ought to, have to, should, must 以及 need 的用法情态动词综合练习 2. 构词法二. 教学重难点： 1. 情态动词 ought to 与 should 的用法should 作为情态动词，表示“劝告”、“建议”，常译作“应该”。如：You should keep your promise.你应该信守诺言。Young people should respect old people.年青人应该尊重老年人。ought 无人称和时态的变化，后接带 to 的动词不定式。ought to 可表示“义务”、“要求”、或“劝告”，常译作“应该”、“应当”等。此时和 should 差不多，只是语气稍重一些。如：You ought to start at once.你应该立即开始。Such things ought not to be done.不应该做这种事情。（注意 ought to 的否定式的写法）ought to 有时可以表示“非常可能”的意思，常用于第三人称中。如：——Ought he to go?他有可能去吗？——Yes, he ought to.是的，很可能。If she is completely well, she ought to be back at school today.如果完全康复的话，她很有可能今天来上学。2. must 和 have toshould 和 ought to 用来表示“劝告”，而 must 和 have to 则用来表示“强烈的要求”。上一节已经为大家介绍过 must 和 have to 的区别，这里大家还要体会它们与 should 及 ought to 的含义差别。下面来理解以下句子的含义及差别。You must eat a balanced diet to stay healthy.You should eat a balanced diet to stay healthy.You must get up early.You have to eat three meals a day if you want to be able to study hard.You must not eat the same kind of food at every meal.You needn’t eat meat every day.情态动词练习题： 1. 用 should, shouldn’t, must, mustn’t, needn’t, have to, don’t have to 填空1）Bill’s room isn’t very interesting.
