    If a diver surfaces too quickly, he may suffer the bends. Nitrogen (氮) dissolved (溶解) in his blood is suddenly liberated by the reduction of pressure. The consequence, if the bubbles (气泡) accumulate in a joint, is sharp pain and a bent body—thus the name. If the bubbles form in his lungs or his brain, the consequence can be death.

    Other air-breathing animals also suffer this decompression (减压) sickness if they surface too fast: whales, for example. And so, long ago, did ichthyosaurs. That these ancient sea animals got the bends can be seen from their bones. If bubbles of nitrogen form inside the bone they can cut off its blood supply. This kills the cells in the bone, and consequently weakens it, sometimes to the point of collapse. Fossil (化石) bones that have caved in on themselves are thus a sign that the animal once had the bends.

    Bruce Rothschild of the University of Kansas knew all this when he began a study of ichthyosaur bones to find out how widespread the problem was in the past. What he particularly wanted to investigate was how ichthyosaurs adapted to the problem of decompression over the 150 million years. To this end, he and his colleagues traveled the world's natural-history museums, looking at hundreds of ichthyosaurs from the Triassic period and from the later Jurassic and Cretaceous periods.

    When he started, he assumed that signs of the bends would be rarer in younger fossils, reflecting their gradual evolution of measures to deal with decompression. Instead, he was astonished to discover the opposite. More than 15% of Jurassic and Cretaceous ichthyosaurs had suffered the bends before they died, but not a single Triassic specimen (标本) showed evidence of that sort of injury.

    If ichthyosaurs did evolve an anti-decompression means, they clearly did so quickly—and, most strangely, they lost it afterwards. But that is not what Dr Rothschild thinks happened. He suspects it was evolution in other animals that caused the change.

    Whales that suffer the bends often do so because they have surfaced to escape a predator (捕食动物) such as a large shark. One of the features of Jurassic oceans was an abundance of large sharks and crocodiles, both of which were fond of ichthyosaur lunches. Triassic oceans, by contrast, were mercifully shark- and crocodile-free. In the Triassic, then, ichthyosaurs were top of the food chain. In the Jurassic and Cretaceous, they were prey (猎物) as well as predator—and often had to make a speedy exit as a result.

(1)、Which of the following is a typical symptom of the bends?
A、A twisted body. B、A gradual decrease in blood supply. C、A sudden release of nitrogen in blood. D、A drop in blood pressure.
(2)、The purpose of Rothschild's study is to see ______.
A、how often ichthyosaurs caught the bends B、how ichthyosaurs adapted to decompression C、why ichthyosaurs bent their bodies D、when ichthyosaurs broke their bones
(3)、Rothschild's finding stated in Paragraph 4 ______.
A、confirmed his assumption B、speeded up his research process C、disagreed with his assumption D、changed his research objectives
(4)、Rothschild might have concluded that ichthyosaurs ______.
A、failed to evolve an anti-decompression means B、gradually developed measures against the bends C、died out because of large sharks and crocodiles D、evolved an anti-decompression means but soon lost it

    Kunta wondered why the white people had done this to him. Born a free man, he was now in chains. Heavy iron chains around his feet and hands were fixed to a metal bar that ran round the hall about ten centimeters off the ground. He was just able to lie down on the ground, but could not stand up.

    Kunta had been seized in the forest and then hit on the head with a hard object. When he woke up, his hands and feet had already been tied together. What shocked him most was that the men who carried him were black. He reasoned with them, and tried to persuade them to set him free. But they would not listen to him. When they came to the river, a white man was waiting in the boat for them. There was an argument about money, so it seemed, in a language that Kunta did not understand. Finally, Kunta was thrown into the bottom of the boat and covered with an old smelly cloth. The men took him in their boat to the castle on the coast where he was now held prisoner.

    Another thing which shocked Kunta was that women were held in the castle too. He could hear their crying, also children's voices. What was to become of them all, he wondered. For all his life, he had known that people suddenly disappeared from their villages. He had known that it was not safe to travel alone in the forest near the coast. But why did white people want to catch Africans and put them in chains? Would they be killed or even eaten? The situation seemed hopeless and he knew his life was in danger.

    Worse was to come. A few days later about 140 black people were taken and put on a tall sailing ship waiting off the coast. Once on the boat, they were taken below and their chains were fixed to two bars that ran the length of the ship. Their feet were fixed to one bar and their hands to another bar. Thus they lay on hard wooden boards, unable to stand up or move around.

    The sea journey lasted over sixty days and nights. They had rough weather and Kunta's back bled from rolling over on the hard wooden boards. Many of the men fell sick with fever. They sighed and cried out for more water, but food and water were only given out once a day. Once in a while sailors came down, Kunta thought, to carry sick men upstairs for treatment. When the ship finally arrived in a port, the wooden cover was opened wide and Kunta could see in daylight for the first time across the part of the ship where he had been chained. About a third of the people who had been chained up below at the beginning of the journey were missing.

    Why are certain people so memorable, while some fade from our memories over time? This question crosses my mind often; there are many possible answers. When you are raising children, you realize that some people become very important to them, draw them in, accept and respect them. These people change them.

    Several examples come to mind with my youngest son. He was always more comfortable around his dad's friends than his own. He loved to spend time with them, fish with them, listen to their stories and just be with them.

    He has experienced the loss of several really meaningful friendships over the past few years, and it has been very painful for him. One, Dr. George, was a neighbor and fishing buddy who would call to see if Ken could go fishing with him. Dr. George always said Ken was the son he never had and that it meant everything to him. He died very suddenly while fishing with all of his best buddies a few years ago. The huge hole that left in so many lives simply cannot be filled — for Ken it was immensely painful.

    There was another fishing buddy of his dad's, Frank, who was always fun to be around. Ken was very young then, but he really enjoyed getting along with "the guy" when they were fishing. Frank and his family went to the Keys in the same week as we did one year ago and the memory remains to this day. Cheerful and happy, he was able to laugh at himself and accept everyone's abilities or lack of them, all qualities that impressed Ken so much.

    When he became deadly ill, Ken drove from his home in North Carolina to Florida for an overnight visit with him. He died a short time later. The day after his funeral (葬礼), Frank came to Ken in a dream and asked if he would take care of his wife, Carol. To Ken this was very meaningful, and today they share a special bond that Frank somehow knew would be important for them both.

    Most of us feel very tired after working for eight hours a day, five days a week. When we get home, we watch at least one film because it's well-deserved and the only time we get to "relax" before going to sleep. Wake up and repeat. No wonder you feel tired. So how do you get out of this vicious circle? How do you restart your life?

    ⒈YOUR MINDSET

    "Oh man, another one of these self-improvement things. I hope I can do it, but I've tried these things before, and I just never stick to it."

    This was something I used to say to myself every time I try to start something new for myself. There's a fear-driven side of your brain which tells you, "You can't do this."

    What can you do? Well, the tip here is to talk to yourself like you're talking to a friend, or a coworker. So the next time you try something new, be kind to yourself like you would be kind to others. You are your own worst critic. But you can also be your firm defender.

    ⒉YOUR DIET

    If you are looking at what you eat for the reason to feel energized, then the general rules are:

    1) Eat when you're hungry. Don't eat when you're not.

    2) Be mindful when you eat. Chew at least 20 times. Let yourself taste and digest your food.

    3) Don't do three things at once when you're eating. Your body wasn't made for that.

    4) Preferably, eat "real" food. Eat what your great-grandmother would recognize as food.

    Don't let your days pass by in a boring way. Start by re-examining these key habits in your life to build a body that can start doing things you want.

    ⒊YOUR SLEEP

    Without enough sleep, we're basically going through the day drunk. This means tiredness, difficulty to respond quickly and smartly to anything that comes up. The sleeping hours needed for an average adult ranges from 7 to 9 hours.
