[要点] 在英语中，我们常用 A long time ago, there was a ...（很久以前，有一个/位……）这样的句式用于讲故事的开头；也可用Once upon a time, there was a ...（从前，有一个/位……）等句式。
例如：Once upon a time, there was a poor old fisherman. 从前有一位贫穷的老渔夫。
[随身练] 翻译句子。
很久以前，有一位名叫汉斯的老实人。
_____________________ an honest man called Hans.
2. One day, a wise old man came to the palace and the king challenged him to a game.(P19)
[要点] challenge意为“向……挑战”，其后通常跟人作宾语。challenge sb. to …是常用
结构，意思是“向某人挑战……”。例如：
Their school challenged ours to a football match. 他们学校向我们学校挑战，要进行足球比赛。 [随身练] 翻译句子。
我想向他挑战，要跟他下一盘棋。
I want to _______ him _______ a game of chess.
3. Wouldn’t you like gold or silver instead?(P19) [要点]
1）or为并列连词，用于连接同等成分的词、短语等。or表示选择，意为“或者， 还是”，用于肯定句或选择疑问句中。or也用于否定句中，表示“和，与”（注意and用于肯定句中）。例如：
You can go by air or by train. 你可以坐飞机去，也可以坐火车去。 There isn’t any air or water on the moon.月球上既没有空气也没有水。
2）instead 为副词，意思是“代替、顶替”。instead常位于句末，用于两个各自独立的句子或并列句的后一句中，也 可用于带有状语从句的主句中。例如：
Mr Black was ill, so she was taking hisclass instead. 布莱克先生生病了, 因此她在代他的课。
4
If you can’t go, I will go instead. 如果你不能去，我替你去。
instead也可位于句首，连接上下句。通常是上句含有否定的意义，然后用instead引出下句，提出相反的情况。这时instead常意为“而是”、“相反”。例如：He didn’t go to the park. Instead he went to the zoo.他没去公园，而是去了动物园。 [随身练]改错。 The baby is too young. He can’t speak and walk.____________________________________.
Task Ⅲ 疑难解析。
[疑难]在I can see nothing but an empty field ...这个句子中，nothing but该如何理解？
[解析] nothing but意为“只是、只不过”，相当于only，后跟名词短语。例如： There is nothing but a card in the box. 盒子里面只有一张卡片。
nothing but 也可用于 want, like, decide,hope 等可跟动词不定式的动词后面。 例如：
I want nothing but to speak to you all these days. 这些天来我只想和你说说话。
