Stephen Powelson’s Amazing Memory

When Stephen Powelson was nine, his school organized a (1) weekly contest in memorizing passages from the Bible. Stephen paid (2)no attention until he was chided* for (3) not competing. The next Sunday he surprised everyone by (4) reciting all the passages for the (5) entire year.

As a teenager in prep school, Stephen took Greek. His teacher (6) assigned 21 lines of the Iliad* to be memorized (7) in a week. At the end of the hour - though he (8) insisted he paid full attention to the (9) lecture - Stephen knew all 21. He went on to memorize the first (10) 100 lines.

In 1978, for the first time (11) since college, Powelson, now 60, had some (12) spare time. To keep his mind active, he reread the Iliad and (13) discovered that he still knew the first 100 lines (14) by heart.

That someone could memorize so much between ages 60 and 70 is (15) astonishing to most people, who are (16) convinced that memory (17) worsens as we grow older.

Powelson's method is to (18) read a book into his tape recorder, then read it several more times, making sure he understands (19) each word. "Also," he says, "I attempt to (20) visualize myself as part of the action."

Part 2 Listening for Gist

You might not know how rarely images are viewed directly through telescopes. The most common way to observe the skies is to photograph them. The process is very simple. First, a photographic plate is coated with a light-sensitive material. The plate is positioned so that the image received by the telescope is recorded on it. Then the image can be developed, enlarged, and published so that many people can study it. Because most astronomical objects are very remote, the light we receive from them is rather feeble. But by using a telescope as a camera, long time exposures can be made. In this way, objects can be photographed that are a hundred times too faint to be seen by just looking through a telescope.

Section Two Listening Comprehension

Part one Dialogue

Tunisian Holiday

(Someone is enquiring about the Tunisian holiday.)

Agent: Hello, Bath Travel.

Client: Hello, I'd like to find out more about your Tunisian holiday for amateur archaeologists. I've read about it in the paper, but I'd like to know more about what is involved.

Agent: You mean you'd like to know the itinerary?

Client: Yes, that's right.

Agent: All right. Just briefly, you arrive in Tunis at midday on the first day and go by coach to La Marsa. Then there is a short briefing by the archaeologist and then the rest of the day you are free to explore.

The second day you get up before dawn and go to Carthage to see the sunrise. You have breakfast and a lecture there and then go by coach to Mansoura, where there are beautiful coves. After lunch you can walk along the beach, to Kerkouane.

The walk takes about four hours. Kerkouane is one of the most recent and most exciting sites. Then by coach to Kelibia, a fishing village, in time for sunset over the harbor.

Client: That sounds rather a long walk.

Agent: Well, it's an easy walk. Flat all the way, and very pretty. But you can go by coach, if you prefer. The third day you spend in Hammamet on Cap Bon, and the day is free to enjoy the town. It's a lovely old town and resort. And the fourth day you take the coach to the ruin of EI Djem, which is a magnificent amphitheatre*. You have lunch in Sfax and then you take the ferry to the beautiful Kerkennah Islands. Client: Islands, you say?

Agent: Yes, they're very peaceful and you spend the fifth day there. The fishermen will take everyone out on their sailing boats and there will be a fishermen's picnic. On the sixth day you visit the Great Mosque of Kairouan and have a picnic lunch. Then take the coach to the lovely port of Bizerte for the last night. And the final day there is a visit to the ancient Roman capital of Utica with its fantastic mosaics* and then a coach to Tunis International Airport.

Client: Have you got a full brochure which gives more details?

Directions: Listen to the dialogue and complete the following itinerary.

Part 2 Passage

Mexican Gray Wolf

1)After more than a century of assault by humans, the wolf population had

dwindled to no more than a handful by the 1970s in Mexico and the American southwest.

2)The program is now about halfway to meeting its goal of a "wild" population of

at least 100 wolves covering more than 12,800 square kilometers.

3)Decisions about mating, movement among the 45 captive-breeding facilities

and releases into the wild are made by a US-Mexican committee of scientists, landowners and others.

4)A wolf with rare genes - until it has successfully reproduced - will never be

released because of the high mortality rate in the wild.

5)The recovery program is gradually moving away from freeing captive-born

wolves, as the population of pups born free takes off.
