I dare to swim across this river. (我敢游过河去。)b. He does not dare(to) answer .(他不敢回答。)3、have to的含义与must相似,两者往往可以互换使用,但 have to有各种时态,且强调客观需要,意为不得不”。例如：I have to leave because of the bad weather. (因为天气不好,我不得不离开了。)4、had better后接动词原形,意为“最好”,用于现在时或将来时,可用于一切人称,没有任何词形变化。had better的否定式是在其后加not,疑问式是把had和not提前。例如:a. You'd better sit here and have a rest. (你最好坐在这儿休息一下。)b. She had better not tell lies any more.  (她最好再也别撒谎了。)c.Hadn' t the doctor better see him?  (医生是不是去看看他比较好?)Step 6 Food comments Teach some new words of this part before so that the activity goes well.(BBQ,tender,steak,sauce, slightly,incredibly,pizzeria,vegetarian,bitter,bakery,cheesecake,creamy,recommend)Activity 4—Pair-work1)  T invites Ss to talk in pairs about the food in the pictures using words they consider appropriate.
