Lesson 78 The last one?After reading an article entitled 'Cigarette Smoking and Your Health' I lit a cigarette to calm my nerves. I smoked with concentration and pleasure as I was sure that this would be my last cigarette. For a whole week I did not smoke at all and during this time, my wife suffered terribly. I had all the usual symptoms of someone giving up smoking: a bad temper and an enormous appetite. My friends kept on offering me cigarettes and cigars. They made no effort to hide their amusement whenever I produced a packet of sweets from my pocket. After seven days of this I went to a party. Everybody around me was smoking and I felt extremely uncomfortable. When my old friend Brian urged me to accept a cigarette, it was more than I could bear. I took one guiltily, lit it and smoked with satisfaction. My wife was delighted that things had returned to normal once more. Anyway, as Brian pointed out, it is the easiest thing in the world to give up smoking. He himself has done it lots of times!Lesson 79 By AirI used to travel by air a great deal when I was a boy. My parents used to live in South America and I used to fly there from Europe in the holidays. A flight attendant would take charge of me and I never had an unpleasant experience. I am used to traveling by air and only on one occasion have I ever felt frightened. After taking off, we were flying low over the city and slowly gaining height, when the plane suddenly turned round and flew back to the airport.While we were waiting to land, a flight attendant told us to keep calm and to get off the plane quietly as soon as it had touched down. Everybody on board was worried and we were curious to find out what had happened. Later we learnt that there was a very important person on board. The police had been told that a bomb had been planted on the plane. After we had landed, the plane was searched thoroughly. Fortunately, nothing was found and five hours later we were able to take off again.

1、SUSAN：That was quick! Have you finished already?
上一句说道太干了，他必须去浇水。浇水的动作发生在SUSAN说这句话之前，已为过去，而且SUSAN说“Have you finished already?”用了现在完成时，也强调了这件事发生在过去，对现在有了影响。所以“That was quick”用过去时。
2、PETER：That was a pleasant surprise.
上一句说道“It's raining.”说明下雨这件事发生在过去，到目前为止一直延续。PETER说那真是一个大的惊喜指的是下雨这件事，所以用过去时。
学数学的小窍门
1、学数学要善于思考，自己想出来的答案远比别人讲出来的答案印象深刻。
2、课前要做好预习，这样上数学课时才能把不会的知识点更好的消化吸收掉。
3、数学公式一定要记熟，并且还要会推导，能举一反三。
4、学好数学最基础的就是把课本知识点及课后习题都掌握好。

这句话前面的PETER所问的是根据主观上来说的，就是说PETER自己认为必须浇花园，主观的“必须”用must，第三个must也是一样的道理，而SUSAN问他是否是have to,就是问他有没有特别重要的客观上的理由，即是带有强制性的“不得不”之意。问答双方所站的角度一主一客，所以措辞也不同。望采纳
哦、起床…
首先，这个新概念的课文的语法要点是让学员掌握表示“必须”的must和“不得不”的have to 的用法。结构上，must 和have to 都必须接动词原型使用，主要的区别在于语意上。“某人 must do 某事” 强调做动作在主观上的必要，而“某人 have to do 某事”则侧重强调一种“被迫”性质，也就是客观限制主体“不得不”做出这样的动作。明确了上面的用法，下面是你的每个句子的解答：1. 课文 I must water the garden first. 我得先给花园浇水。 我写的i must have water to garden first。可以吗解答：不可以。首先本句water是动词，意为“给……浇水”，而且由于语意有重复，must 和have to 不能同时连续使用。若用have to 可改为：I have to water the garden first.（别丢冠词）2. 课文Do you have to water it now? 你一定得现在浇吗？ 我写的do you have to now可以吗？我写的是省略的写法。。。解答：不可以，因为have to在语法上相当于一个情态动词，而且本句是一般疑问句。在这种句式中，必须出现句子主语“你”真正的动作，必须加上“你”的动作“浇水”（water），或者代替water的一个动词do，才能让句子完整。 可以说：Do you have to do it now? （宾语it也不能省略）3课文 What a nuisance! 真讨厌！ 我写的what a terrible可以吗解答：不可以。因此 terrible 永远是形容词，不能单独放在冠词a 后面使用。而且terrible 的主要意思是“糟糕的；令人恐怖的”，这两个意思和“真讨厌”是有一定差别的，不能随意替换。4课文That was quick! 好快啊！ 我写的how was quickly可以吗解答：不可以。因为课文原句的that 是指示代词，表示课文上文提到的那位男士浇水这件事，因为女士不知道下雨了，所以她才说“那（你浇水的事）可真快啊！” how是个副词，没有that这里的作用，它用在感叹句的时候必须遵循下面的结构：How + 形容词或副词 ＋ 陈述句 ！ 例如：How beautiful she is! 她可真漂亮啊！ How fast he runs! 他跑得可真快！ 另外，quickly 是副词，quick是形容词，用法不同，不能随意替换。5课文Have you finished already? 你已经浇完了？ 我写的did you finishi it可以吗解答：不可以。因为本句用 现在完成时 have finished 搭配副词 already 表示“已经做完了某事”，而你的Did you finish it? 是一般过去时，只有“完成了吗？”的意思。英语中的现在完成时初学者不易掌握，是因为它和一般过去时相比，更强调这件事对当前的影响和带来的结果。本文中之所以这么问，就是因为那位女士觉得男士不可能这么快浇完水，采用already（已经）这么询问。要表达“我已经做了某事”，一般都用现在完成时。（见新概念1第85课至89课）6课文Yes. Look out of the window. 是的。你看看窗外。 我写的yes, you see windows outside可以吗解答：不可以。因为“look out of 某物”这个短语就可以表达“向某物外面看”的意思，是“固定搭配”。与look相比，see强调看得专注、仔细，甚至有“弄明白”的意思，这里，外面下雨了，是很直观的事情，look就可以。另外，outside 这个词你会在字典里发现有很多词性，很多意思，当它放在句尾的时候，可以是副词（在外边）或是名词（外侧，屋外），强调静止的状态，但本句强调“向外看”的动作趋势，所以用短语out of ，不用 outside。7课文That means You don't need to water the garden. 这就是就是说，你不必给花园浇水了。 我写的that means you needn't have water to the garden可以吗？为什么要写don't need，need不是可以做情态动词吗？为什么不写to,to表目的啊？解答：这个问题很好！也是本课另一个重要知识点。首先need既可以当情态动词，直接跟动词原型，也可以当作实义动词（也就是大多数动词的用法）。这里的意思是“你不必浇水了”，表示“没有必要做”的含义，一般就可以用“don't need to do” 或者 “don't have to do”，同时“needn't do”也是允许的，只是现代英语不常用了。可以看出，don't need to do 结构中，need 是实义动词的用法，接to do（动词不定式）做宾语，而不是情态动词的用法。8课文It means I can have tea, instead. 这意味着我反倒可以喝茶了。 我写的it means i have tea instead可以吗？ 解答：不可以。因为这里can 这个情态动词表示说话人的一种语气。相信你可以体会出，主人公说出这句话，是想表达类似“我总算可以（有机会、有可能）来喝茶了”的意思，对吧？can正是用来表达这种“可能性”的一个情态动词。没有了它便没有了这层语意。希望你能满意我的解答。有问题可以继续提问。
