课文原文
Lesson 91 Three men in a basket 三人同篮
A pilot noticed a balloon which seemed to be making for a Royal Air Force Station nearby. He informed the station at once, but no one there was able to explain the mystery. The officer in the control tower was very angry when he heard the news, because balloons can be a great danger to aircraft. He said that someone might be spying on the station and the pilot was ordered to keep track of the strange object. The pilot managed to circle the balloon for some time. He could make out three men in a basket under it and one of them was holding field-glasses. When the balloon was over the station, the pilot saw one of the men taking photographs. Soon afterwards, the balloon began to descend and it landed near an airfield. The police were called in, but they could not arrest anyone, for the basket contained two Members of Parliament and the Commanding Officer of the station! As the Commanding Officer explained later, one half of the station did not know what the other half was doing!

8.2 学习策略建议
策略一：主题词汇记忆法
【航空军事主题卡片】

┌──────────────┐ ┌────────────────────────┐
│ │ │ • Royal Air Force │
│ aircraft │ → │ • pilot │
│ │ │ • airfield │
│ [ˈeəkrɑːft] │ │ • control tower │
│ │ │ • station │
│ n. 飞行器 │ │ • balloon │
│ │ │ • land / descend │
└──────────────┘ └────────────────────────┘
策略二：动作链记忆法
故事法记忆动词链：
你是一名pilot，正在巡逻时notice了一个balloon，
它似乎正在making for某个station。
你立即informed了基地，officer很angry，
因为balloon对aircraft是danger。
他ordered你to keep track of这个strange object。
你managed to circle它一段时间，
终于make out basket里有三个人，
其中一人holding field-glasses。
当balloon over the station时，
you saw他在taking photographs。
Soon afterwards，balloon开始descend，
最后landed near an airfield。
Police被called in，却无法arrest任何人，
因为basket里contained两位MP和Commanding Officer！
策略三：构词法扩展记忆
词族记忆树：
inform (v.通知)
│
┌───────┼───────┐
↓ ↓ ↓
information informative informally
(n.信息) (adj.有益的) (adv.非正式地)
│
↓
informed (adj.见多识广的)
记忆口诀：inform通知你information信息，
内容informative有益，
方式可informal随意。
策略四：搭配块记忆
【高频搭配块】
□ make for + 地点 = 朝...移动
The ship made for the harbor.
□ keep track of + n. = 跟踪/记录
Keep track of your expenses.
□ make out + n. = 辨认出/理解
