⑥ shall在问句中,可表示征求对方意见,与第一人称连用;在陈述句的第二、三人称的主语后或表示“命令”、“警告”、“允许”等。如:Shall we go to the zoo this weekend?(我们这个周末去动物园好吗?)/ He shall bring his own book next time.(他下次必须带自己的书来)

⑦ should可表示“劝告”、“建议”、“惊奇”等意思。We should speak to old people politely.(我们应该礼貌地对老人讲话)

⑧ will表示“意愿”、“决心”等意思,一般与第二人称连用。如:Will you please close the door for me?(请你替我把门关上好吗?)/ I will teach you a lesson.(我要教训你一顿) ⑨would表示过去的“意愿”、“决心”等。He would sit near the fire every time he returned

home.(每次他回到家中总要坐在火炉边)

would也可以表示现在的情况,表达说话人向对方提出的要求,语气比“will”婉转、客

气。在日常会话中,“我想要…”通常用“I would like to”或“I should(I’d) like to”来表示。如:Would you like to have a rest at the moment?(你现在想要休息一下吗?)

would还可以表示过去经常发生的事情。如:Every year parents would tell their children about the boy who would save his people.(每一年父母们总是向孩子们讲述这个将会拯救他的人民的男孩的事)

⑩ need表示“需要”,用于疑问句或否定句。“need”作实义动词时,在肯定、否定、疑问句中都可以用。如:He needn’t do it in such a hurry.(他不需要如此匆忙地做这件事)/ He needs some help.(他需要一些帮助)/ He doesn’t need to bring his football socks then.(那么他就无须带上足球袜了)

⑾ dare是“敢”的意思,用法几乎与“need”完全相同,即在疑问句和否定句中,可以作情态动词,后面用不带“to”的动词不定式。在肯定句中和实义动词一样,后面的动词不定式要带“to”。How dare you say I am a fool?(你竟敢说我是个傻瓜?)/ He didn’t dare to touch the red button.(他不敢触碰那个红色的按钮)

⑿ ‘d better (do)(“最好是”)一般也当作情态动词使用,否定式是:’d better not (do). 如:You’d better sit here and say nothing.(你最好坐在这儿不讲话)/ You’d better not speak because he is sleeping.(你最好不要讲话因为他正在睡觉)
