本课必须熟记的词组：

在we don’t need中，这个need是个普通动词，是个实义 动词，表示“需要”。所以things we don’t need就表示 “我们不需要的东西”。
You needn't wait for me. ＝You don't have to wait for me.
你不必等我。（还没有等） You needn't have waited for me. ＝You didn't have to wait for me. 你不必等我的阿。（已经等过了。）
Comprehension questions：
1 Were you in a shop or a theatre? A shop.
2 Who were you with? My wife.
3 She was trying a hat on, wasn't she? Yes, she was.
4 What did you say to your wife? ‘Do you call that a hat?’
3. mustn’t和needn’t的区别 Needn’t上面讲过是表示“不必、没必要”。
而mustn’t就表示“不应该”。
同时，needn’t也是可以用don’t have to来代替。
You mustn't make a noise. The children are asleep.
你不应吵闹，孩子们都睡了。（这里mustn’t表示 “不应该”。
“我觉得它好看，”我说，“男人有多少领带也不会嫌 多。” “女人有多少帽子也不嫌多。”她回答。 10分钟以后，我们一道走出了商店。 我妻子戴着一顶像灯塔一样的帽子。
• Ten minutes later we walked out of the shop together.
My wife was wearing a hat that looked like a lighthouse! 10分钟以后，我们一道走出了商店。我妻子戴着一顶像灯塔 一样的帽子。
I sat down on one of those modern chairs with holes in it and waited. We had been in the hat shop for half an hour and my wife was still in front of the mirror.
我必须做所有的这些练习吗？ B：No, you needn’t. 不，你不必。 如果你要表达“你必须”的意思时，就用“Yes, you
must.”
当然了，needn’t也可以单句使用，比如来看 我们这课课文中的几次使用： You needn't be so rude about it.
你说话没必要这样不客气。 You needn't have said that.
5 Did she think you were being rude? Yes, she did. 6 How long had you been in the hat shop? Half an hour. 7 What was the remark you suddenly made? ‘We mustn't buy things we don't need.’ 8 How soon did you regret saying it? Almost at once.
英语中实际上有两个 need。
一个是普通动词need，是表示“需要”的意思。
比如：I need a car（我需要一辆汽车。）；
另一个是情态动词need。是表示“必要”。
情态动词的need和can，may等情态动词一样，后接动词原形，但只 用于否定和疑问句，肯定句用must，have to，ought to或 should。也就是说情态动词的need只能表示“不必要”（needn’t） 或是“有必要吗？”（Do you need…）。而如果要表示“有必要、 必须”就使用must，have to，ought to或 sho气，”我的妻子边回答边照 着镜子。
Lesson 41 课文讲解：
Do you call that a hat? Call我们知道最常用的是“打电话”的意思。同时， call还可表示 “把…叫做、称为”，常用于口语和非 正式文体中。在第10课中我们讲到过 name 和 call 的区别，这里再复习一下：
You needn't come with us if you don't want to. 如果你不想去，你不必和我们一道去。 Or: You don't have to (haven't got to) come with us if you don't want to.

Wear在这里是表示“穿、戴”的意思，再比如： Wear a black dress穿一件黑衣服 Wear a diamond earrings 戴一对钻石耳环 Wear the glasses 戴眼镜 Wear perfume 用香水 The girl wears too much make-up. 这个女孩妆化得太浓了。
You needn't drive so quickly; we have plenty of time. 你不必开得那么快，我们有足够的时间。 Or: You don't have to(haven't got to) drive so quickly; we have plenty of time.
语法讲解：need主要有两种用法
1.作为“实义动词”表示“需要”。
2.在needn’t结构中need作为“情态动词”。 needn’t用于否定句，表示“不必”、“没必 要”.
首先来看need作为“实义动词”表示“需 要”。其各种形式的变化都和普通动词一模 一样的：
I need a new hat. I must buy one.
“我们不应该买我们不需要的东西，”我突然发表意 见说，但马上又后悔说了这话。
“你没必要这么说，”我妻子回答说，“我也不必提 醒你昨天买的那条糟糕透了的领带。”
We mustn't buy things we don't need. 首先，这句话中mustn’t表示“不应该”，是表示一种 “禁止”的意思。大家知道：must是表示“必须做某 事”，而其否定形式就是mustn’t，表示“不应该，不准、 禁止”干某事。而和我们前面说的needn’t做比较可以看 出，needn’t表示“不必要，没必要”干某事，但仍可以 干。试比较：
我坐在一个新式的满是网眼儿的椅子上，等待着。 我们在这家帽店已经呆了半个小时了，
而我的妻子仍在镜子面前。
'We mustn't buy things we don't need,' I remarked suddenly. I regretted saying it almost at once. 'You needn't have said that,' my wife answered. 'I needn't remind you of that terrible tie you bought yesterday.'
Lesson 41 Do you call that a hat? 你把那个叫帽子吗？
'Do you call that a hat?' I said to my wife. 'You needn't be so rude about it,' my wife answered as she looked at herself in the mirror.
