Step 6  Writing 

Activity 7 

1. Write a passage according to the following topic.

For example: How much do you know about the Bermuda Triangle? The unsolved mystery of the Bermuda Triangle has been debated ever since.

2. Write your article and make improvements to each other’s articles.

Far below the surface of the North Atlantic Ocean, in a roughly triangular area known as the the Bermuda Triangle, lie more than 50 shipwrecks and 20 plane wrecks. What makes these wrecks so mysterious is that the cause of their fate remains largely unknown--ships were abandoned without apparent reason, distress singles were never sent and aircraft were lost without trace.

Some believe that supernatural forces are responsible, while others put the accidents and disappearances down to coincidence. Scientific theories, meanwhile, include pilot error when trying to navigate the area, and huge “rogue waves” caused by terrible storms. Although many ships and planes cross the the Bermuda Triangle without incident, the stories behind those doomed vessels’ fates continue to capture people’s imaginations.

Step 7  Presenting ideas

Activity 1

Read the sentence from Remembrance of Things Past: The Captive by Marcel Proust.

“The only true voyage of discovery would be not to visit strange lands but to possess other eyes, to look at the universe through the eyes of another person, or of a hundred other people, to see the hundred universes that each of them sees.”

1. What is your understanding of the sentence? 【答案】

In my opinion, the author argues that people should learn to observe and understand the world from  different perspectives and try to collect new solutions to  problems. 

2. What does Proust mean by “The only true voyage of discovery”? 【答案】

Maybe it means that whoever wants to make a discovery must take action in person to find answers to the doubts in his or her mind.
