Buses
In the past, many people liked travelling by bus. All passengers had to buy tickets. There was a bus-conductor in each bus. He collected money from the passengers and put the money in a bag. Passengers do not buy tickets now. They put their money in a fare-box instead. In the past, there were only single-decker buses. None of them was a double-decker bus. In the past, travelling by bus was not very comfortable. There were no air-conditioners in the buses．Nowadays, most buses have air- conditioners. Most of the bus-drivers are men, but some of them are women. However, in the past, none of the bus-drivers were women . All of them were women .

重点难点解析
1 . All passengers had to buy tickets．所有乘客必须买票。
▲have和must的异同
在表示“必须”这个意思时，must和have to很接近。只是must强调主观看法，have to强调客观需要，若用来指现在，两者可以换用。不过用have to的场合较多，尤其是在口语中，have to有时可说成have got to．另外，have to能用于多种时态，而must只能用于一般现在时。如：
①I have to get home to do my work.. 我得回家干活。（可能时间或客观情况不允许我再呆下去。）
② We must clean our room every day. 我们必须每天打扫房间。（作为一种义务，无论干净不干净。）
用于否定句时，mustn\'t表示“决不可”“千万不能”，而don\'t have to表示“不必”，相当于needn\'t. mustn、和don\'t have to在意义上有很大的不同。如：
1)We mustn\'t tell her about it．这件事我们决不能告诉她。
2)We don\'t have to tell her about it．这件事情我们不必告诉她。
3)You mustn\'t be late again next time．你下次千万不能再迟到了。（不能用don\'t have to)
2. They put their money in a fare-box instead．取而代之的是他们把钱放进投币箱中。
▲ instead与instead of辨析
instead是个副词，它后面不能跟名词、代词或动名词，而只能作动词的状语或句子的状语，而instead of是复合介词，其后应跟名词、代词、动名词或介词短语。如：
1) If you don\'t want to go, I\'ll go instead．你要是不打算去，我就替你去好了。
2) I will go instead of you．我将代替你去。
3. None of them was a double-bus。它们中没有一个是双层巴士。
▲none of之后除可接可数名词之外，也可以接不可数名词。如：
1) None of the milk can be used．这牛奶一点也不能用。
2) None of the rooms are ready．没有一个房间准备好。
4. Perhaps we won’t travel by ferry any longer. 也许我们不再乘渡船了.
▲no longer 与 not any longer
no longer 与 not any longer的词义是相同的, 它们的区别主要表现在词序上. no longer常位于实义动词之前,连系动词、助动词和情态动词之后, 而any longer在否定句中总是放在句尾. 如:
① He’s no longer at school. 他不再上学了.
② I can’t wait any longer. 我不能再等了.

重点难点解析
1．They are going to make a new one．他们打算做一个新的。
▲对于将要发生的事，或打算，计划，决定要做的事情，都以be going to十动词原形的句型来表示，其中be动词是否用am, is，are决定于主语。如：1）He is going to be back soon．他不久将回来。
2）I am going to buy a new bike．我要买一辆新自行车。
▲此处one用作不定代词，它可指代刚提到的人或可数的物，也可泛指人们或一个人，但不可指代不可数名词。如：1）I have a red pen, and he has a blue one。我有支红钢笔，他有支蓝钢笔。
2）One could see that he was very happy．人们能看得出他非常高兴。
2. Let\'s start collecting things．让我们开始收集东西吧。
▲let是及物动词，意思是“让”“请让”“允许”“做……吧”等，其过去式仍为let。let位于句首，引导祈使句。let后面跟somebody作宾语时，在somebody之后的动词不定式，需要省略不定式符号to。
a. let用于祈使句，表示“请让” “做……吧”。如：
1）0K, let me try！好，让我试一试吧！（省略了主语you的祈使句）
2）Let me have a look．请让我看一看。（省略了主语you的祈使句）
3) Let\'s do it together．咱们一起做吧。（祈使句）
4）Let\'s begin our class．我们开始上课吧。（祈使句）
b. let用于第三人称作宾语的句子中，表示“让”。如：
1）Let him think about it for a minute．让他考虑一会吧。
2）Let them feel it场hand．让他们用手摸一摸。
c. let用于不省略主语的句子中，表示“允许”“让”。如：
1）After my explanation, she let her da回lter go with her classmates.
在我解释过后，她允许女儿和同学们一起去了。
2）The father let his son have a rest before moving to Lesson Nine.
那位爸爸让儿子在进行第九课之前休息休息。
3 . First,…Next, Then... Finally,…首先，……接着，……然后……最后，……
▲在汉语中，我们常用“某人先做了某事，然后作了某事，最后做了某事”来表示某个人做事情的先后顺序。在英语中，我们也可以在句子前加一些表示先后顺序的词语来表示动作的先后顺序。常用的词语有first...then…， finally/in the end...。如：
1）Let\'s first get everything ready. Then we will read the directions. Finally/In the end, we must do it very carelly.
我们先把一切准备好。然后我们来看说明书。最后，我们一定要非常小心地去做。
2）What a shame！First he gave me the book as a present. Then he got it back from me. And finally/in the end, now, he said he would give it to me again. I will never take his things, never.
真丢人，他先是把这本书作为礼物送给我。然后，他又把它要了回去。最后，就是现在，他又要把这本书送给我。我永远也不会要他的东西，永远不会。
