I shall never forget the night, a few years ago, when Marion J. Douglas was a student in one of my adult-education classes. He told us how tragedy had struck at his home, not once, but twice. The first time he had lost his five-year-old daughter. He and his wife thought they couldn’t bear that first loss; but, as he said, “Ten months later, God gave us another little girl and she died in five days.”
This double bereavement was almost too much to bear. “I couldn’t take it,” this father told us. “I couldn’t sleep, eat, rest or relax. My nerves were entirely shaken and my confidence gone.” At last he went to the doctors: one recommended sleeping pills and another recommended a trip, but neither helped. He said, “My body felt as if it was surrounded in a vice(大钳子), and the jaws of the vice were being drawn tighter and tighter.” The tension of grief(悲伤) --- if you have ever been paralyzed(使瘫痪) by sorrow, you know what the meant.
“But thank God, I had one child left --- a four-year-old son. He gave me the solution to the problem. One afternoon as I sat around feeling sorry for myself, he asked, ‘Daddy, will you build a boat for me?’ I was in no mood to build a boat; in fact, I was in no mood to do anything. But my son is a persistent fellow! I had to give in. Building that toy boat took me about three hours. By the time it was finished, I realized that those three hours spent building that boat were first hours of mental relaxation and peace that I had had in months! I realized that it is difficult to worry while you are busy doing something that requires planning and thinking. In my case, building the boat had knocked worry out of the ring. So I determined to keep busy.”
“The following night, I made a list of jobs that ought to be done. Scores of items needed to be repaired. Amazingly, I had made a list of 242 items that needed attention. During the last two years I have completed most of them. I am so busy now that I have no time for worry.”
No time for worry! That is exactly what Winston Churchill said when he was working eighteen hours a day at the height of the war. When he was asked if he worried about his huge responsibilities, he said, “I am too busy. I have no time for worry.”

Humpback whales

Humpback whales are sometimes called performers of the ocean. This is because they can make impressive movements when they dive. The name “humpback”, which is the common name for this whale, refers to the typical curve shape the whale’s back forms as it dives.

   Sometimes the humpback will dive with a fantastic movement, known as a breach. During breaching the whale uses its powerful tail flukes to lift nearly two-thirds of its body out of the water in a giant leap. A breach might also include a sideways twist with fins stretched out like wings, as the whale reaches the height of the breach.

   A humpback whale breathes air at the surface of the water through two blowholes which are located near the top of the head. It blows a double stream of water that can rise up to 4 meters above the water.

   The humpback has a small dorsal fin located towards the tail flukes about two-thirds of the way down its back. Other distinguishing features include large pectoral fins, which may be up to a third of the body length, and unique black, and white spots on the underside of the tail flukes. These markings are like fingerprints: no two are the same.

   Humpback whales live in large groups. They communicate with each other through complex “songs”.

Quick Facts

Size:

14m~18m in length

30~50 tons in weight

Living environment:

Open ocean and shallow coastline waters

Migration:

From warm tropical (热带的) waters, where they breed, to cold polar waters, where they eat.

Diet:

Shellfish, plants and fish of small size

Hunting:

Sometimes in groups, in which several whales form a circle under the water, blowing bubbles that form a “net” around a school of fish. The fish are then forced up to the surface in a concentrated mass.

Current state:

Endangered: it is estimated that there are about 5000~7000 humpback whales worldwide.

 

1.According to Quick Facts, a humpback whale ______.

A. cannot survive in waters near the shore          B. doesn’t live in the same waters all the time

2.To make a breach, a humpback whale must ______.

A. use its tail flukes to leap out of the water     B. twist its body sideways to jump high.
