Revision

Check the homework exercises. Step 3 Presentation Present the students some pictures of the early sailors and explorers, as well as the pictures of navigating tools, including maps, compass, etc. Step 4 Pre-reading Ask the students to read the 3 questions of the passage A Hard Expedition: 1.

Why did the crew get lost on the sea? A. Because the wind was roaring. B. Because they were at the mercy of the sea. C. Because they couldn’t reckon the precise latitude and their magnetic compass was awkward and not reliable. 2.

Which of the following is true according to the passage? A. The horizon, celestial objects overhead, seaweed, tide and logs with a knotted rope helped the crew make sure of the sailing course precisely. B. Sailing alongside cliffs was a good way to avoid being on a random course heading nowhere. C. The crew suffered from not only starvation and thirst but also psychological problems. 3.

What result did this incident lead to? A. This incident led to that all the crew lost heart. B. This incident led to a miracle. C. This incident led to that portable equipment for secure voyage was simplified and updated. Step 5 Reading 1. Ask the students to read the passage A Hard Expedition: In 1662, an expedition to the North Pole

set loose

from the equator.

The

Encyclopedia

records the background of this exploration.

After outward departure at dusk, the crew

deposited their parcels and did their routine. But they couldn’t reckon

the precise

latitude. And the

magnetic

compass was awkward

and not reliable. Gradually, the crew, who were at the mercy of the sea

and roaring wind when offshore,

lost their way. They had to use the horizon, celestial objects overhead, seaweed, tide and logs with

a knotted rope as the course reference. To avoid being on a random course heading nowhere, they sometimes even sailed alongside

cliffs,

whose shortcomings were obvious. The dilemma lasted long. Starvation and thirst caused psychological tension. Foreseeing the minimum chance of escaping the jaw of death, the crew lost heart and even allowed the seabirds to swoop to tear

and peck them. With so many hardships and drawbacks, their survival was a miracle.

This incident increased the tendency of a compulsory reform on nautical equipment for secure voyage. Portable equipment

was simplified and updated.

【参考译文】

一次艰难的远征

1662年，一支远征队从赤道向北极出发，百科全书记载了这次探险的背景。

船只在黄昏时分启程，船员们放好包裹，开始执行日常事务。但是他们无法计算准确的纬度，磁性指南针也很难操作，不太可靠。渐渐地，离开海岸后就完全受大海和呼啸的风主宰的船员们迷了路。他们不得不使用地平线、头顶上的天体、海草、潮汐和绑有打结绳子的圆木做航线参考。为了避免过于随意的航线把他们带到不知名的地方，他们有时甚至还沿着悬崖航行，这样做的缺点是显而易见的。这种困境持续了很长时间，饥饿和口渴引起了心理的紧张不安。因为预见到很难有（最低的）机会从鬼门关逃脱，船员们失去了信心，甚至任由海鸟扑下来撕扯、啄食他们的身体。经历了那么多的艰难和险阻，他们能够幸存下来真是奇迹。

这一事件促进了为了安全航海，必须革新航海设备的趋势，便携设备由此得到了简化和更新换代。
