课文原文
In future, astronauts will be required to descend from a spaceship while it is still in space and to return to it. The ability to do this will be necessary in future flights to distant planets. Scientists are now trying to discover if this is possible. The spaceship Astra which left the earth a short time ago, will be travelling three hundred miles into space. At a certain point, the Astra will stop for a short time and an astronaut will attempt to leave the stationary spaceship and then return to it. We shall not know whether the experiment has been successful until we have received a radio message. The first message is expected to arrive at 7 o’clock this evening. By that time, the Astra will have been flying through space for seventeen hours and will have circled the earth a great many times. When the first radio messages have been received, the results of the trip will be announced immediately.

8.2 学习策略建议
8.2.1 主题联想法
以**“太空探索”**为核心构建词汇网络:
太空探索 (Space Exploration)
│
┌───────────────┼───────────────┐
▼ ▼ ▼
人员与角色 航天设备 任务动作
• astronaut • spaceship • descend
• scientist • Astra • return
• discover
• attempt
• announce
8.2.2 对比记忆法
离开 vs 返回:
- leave the spaceship → return to it
- 课文核心动作对立
时间对比:
- a short time ago(过去)→ in future(未来)→ by that time(将来某时)
运动状态:
- stationary(静止)vs flying/circling(运动)
8.2.3 场景记忆法
“太空行走实验”场景链:
- 宇航员需要下来 (descend from) →
- 从静止的 (stationary) 飞船 →
- 尝试 (attempt) 太空行走 →
- 然后返回 (return to) →
- 实验是否成功 (successful) →
- 结果将立即宣布 (announce immediately)
8.3 输出练习建议
8.3.1 造句练习
用以下句型造句:
- be required to do…
- the ability to do… will be necessary
- try to discover if…
- not…until…
- by that time…will have…
8.3.2 翻译练习
翻译以下句子:
- 科学家们正在试图发现这是否可能。
- 到那时,飞船将已经在太空中飞行了17个小时。
- 宇航员将尝试离开静止的宇宙飞船。
