教学重点与难点
1.need作为情态动词和实意动词的用法
need作为情态动词仅用于否定句或疑问句;
用情态动词must提问时, 否定回答用needn’t ;
用need做情态动词提问时, 肯定回答用must .
I needn’t show her the answer to the question, need I?
我不必把这个问题的答案给她看, 是吗?
“Must you finish your homework today?”
“你必须今天完成作业吗?”
“Yes, I must”（“No, I needn’t.”）
“是的, 我必须今天完成.”（“不, 我不必今天完成.”）
“Need she go at once?”
“她马上就得走吗?”
“Yes, she must.”（“No, she needn’t.”）
“是的, 她必须马上走.”（“不, 她不必马上走.”）
need作为实意动词有它作为动词的多种形式, 可以用于各种
句型之中, 表示不同的意义.
实际上need较多地用于实意动词, 较少用于情态动词.
在表示过去意义时, 常用作实意动词, 而不用作情态动词.
“Does he need to wash his hands?”
“他要不要洗手?”
“Yes, he does. / No, he doesn’t.”
“是的, 他得洗. / 不, 他不必洗.”

2.关于否定疑问句
否定疑问句一般用来表示惊异, 责难, 赞叹, 邀请或建议等,
一般不要求对方用Yes或No来回答.

那真是一个奇妙的地方, 你难道不和我们一块去? (惊异)

再喝一杯茶好吗? (邀请或建议)
Mom, can’t Lily do it?
妈妈, Lily就不能做吗? (责备)
有时对不太有把握的事情向对方提问, 也可以用这种否定疑问句;
这时答语应该和附加问句的答语一样, 如果是肯定的, 要用Yes,
否则就用No, 这跟汉语的习惯很不相同.
“Aren’t you in Class Two?”“Yes, I am.”
“你不是二班的学生吧?”“不, 我是二班的.”
“Doesn’t she want to go?”“No, she doesn’t.”
“她难道不想去吗?”“是的, 她不想去.”
