Do you find yourself forgetting where you left your keys or blanking out information on important tests?{#blank#}1{#/blank#}Before your next big exam, be sure to check out some of these tried and tested ways of improving memory.

    Focus your attention on the materials you are studying. Attention is one of the major parts of memory. In order for information to move from short-term memory into long-term memory, you need to actively attend to this information.{#blank#}2{#/blank#}

    Structure and organize the information you are studying. Researchers have found that information is best organized in related groups.{#blank#}3{#/blank#} Or you can make an outline of your notes and textbook readings to help group related concepts (概念).

    {#blank#}4{#/blank#}When you are studying unfamiliar material, take the time to think about how this information relates to things that you already know. By establishing relationships between new ideas and previously existing memories, you can remember the recently learned information.

    Pay extra attention to difficult information. Remembering information at the beginning or end of an article is easy. However, recalling information from its middle can be difficult.{#blank#}5{#/blank#}Another way is to try restructuring what you have learned so it will be easier to remember. When you come across an especially difficult concept, devote some extra time to memorizing the information.

A. Use this approach in your own studies.

B. Try grouping similar concepts and terms together.

C. Relate new information to things you already know.

D. Repeat the information you are studying to improve memory.

E. Try to study in a quiet place and concentrate on your learning.

F. Fortunately, there are things that you can do to help improve your memory.

G. You can overcome this problem by spending extra time memorizing this information.

How to develop courage by overcoming daily fears

    At times, when it comes to courage, we tend to believe it only applies to rare and uncommon situations. Yet our ordinary lives can also be full of courage, even if we are not facing the end of a gun, a wild animal or a dangerous criminal. Courage doesn't just mean doing heroic acts.{#blank#}1{#/blank#} In fact, where there is fear on a daily basis, there are opportunities for you to show your courage. Here are some suggestions to develop courage by overcoming daily fears.

    Recognizing your fears.

    By realizing that you're fearful, you are more likely to get to the bottom of what your fear is.{#blank#}2{#/blank#} You might come to understand that you're afraid of failing or taking chances. You may be fearful simply because you don't have confidence in yourself. The key is not to dwell on your fear, but rather to understand what it is that you're worried about.

    Ask yourself what is the worst that can happen.

    If you hesitate to take action, ask yourself this: what's the worst that can happen? Then prepare to accept it. Then go on to improve on the worst. Is failure the worst thing that can happen? No, absolutely not.{#blank#}3{#/blank#}. Doing nothing is actually the worst thing that can happen. When you take no action, you are assured of getting nowhere.

    Take action.

   {#blank#}4{#/blank#}  You cannot think courage comes just in one day. You need to act to overcome your fear. Your action may put you into discomfort, but you have to just do it. And your action can prevent you from being stuck.

    {#blank#}5{#/blank#} To build up your confidence, you need to do the same thing over and over again. Soon you will discover that less courage is needed because you have already gained mastery. You are able to move decisively forward.

A. Share your fears with others.

B. Practice, practice and practice.

C. So you are already in a comfort zone.

D. Courage comes from taking action

E. Each undesired result is just one more step towards your goal.

F. Finding out what is truly holding you back,

G. You needn't wait for an emergency to occur to develop courage.

    Ask someone what they have done to help the environment recently and they will almost certainly mention recycling. Recycling in the home is very important of course. However, being forced to recycle often means we already have more material than we need. We are dealing with the results of that over-consumption in the greenest way possible, but it would be far better if we did not need to bring so much material home in the first place.

    The total amount of packaging increased by 12% between 1999 and 2005. It now makes up a third of a typical household's waste in the UK. In many supermarkets nowadays food items are packaged twice with plastic and cardboard.

    Too much packaging is doing serious damage to the environment. The UK, for example, is running out of it for carrying this unnecessary waste. If such packaging is burnt, it gives off greenhouse gases which go on to cause the greenhouse effect. Recycling helps, but the process itself uses energy. The solution is not to produce such items in the first place. Food waste is a serious problem, too. Too many supermarkets encourage customers to buy more than they need. However, a few of them are coming round to the idea that this cannot continue, encouraging customers to reuse their plastic bags, for example.

    But this is not just about supermarkets. It is about all of us. We have learned to associate packaging with quality. We have learned to think that something unpackaged is of poor quality. This is especially true of food. But it also applies to a wide range of consumer products, which often have far more packaging than necessary.

    There are signs of hope. As more of us recycle, we are beginning to realize just how much unnecessary material we are collecting. We need to face the wastefulness of our consumer culture, but we have a mountain to climb.

    A kiln (窑) is a type of oven or furnace used to cure (加工处理), harden, or burn certain materials. Depending on which materials are heated in it, a kiln may be square, tunnel shaped, or beehive shaped, and usually made of brick or stone.{#blank#}1{#/blank#} It may be set as low as sixty-five degrees to cure grain or as high as 3,200 degrees to transform limestone to quicklime (熟石灰).

    {#blank#}2{#/blank#} They have a variety of purposes. The cement (水泥) industry uses revolving kilns to heat and separate raw materials. Bricks, pottery, and china made from clay must be fired, or hardened, in kilns. Certain kinds of coal and wood must be kiln-dried （在窑里烘干的）before they can be used. Hobbyists use small kilns to fire a variety of ceramic (陶瓷) objects.

    There are two main types of kilns. A periodic kiln, used to fire certain kinds of delicate china, is raised to a high temperature and then completely cooled before its contents are removed. A continuous, or tunnel kiln contains several chambers, or zones, which heat, bake, and cool a product. Stacks of clay bricks move through a tunnel kiln on tracks{#blank#}3{#/blank#}

    Gas, oil, and coal are all used to heat modern kilns{#blank#}4{#/blank#} But for special jobs, where cleanliness and careful heat（绝热）are important, kilns must be heated by electricity oven though it is more expensive. Small kilns used in the home or in craft shops are also heated electrically because electricity is clean and convenient.

    {#blank#}5{#/blank#} When ancient people discovered that heat hardened some materials, they were able to make durable household objects such as jugs and bowls. Today our museums display many kinds of ancient statues and art objects that have lasted because they had been kiln-dried. They come from lands as far apart as China and Greece.

A. Its temperature may vary.

B. Then they come out, hardened, and cooled.

C. Kilns are used in industry and in craft-making.

D. Kilns have been in use for thousands of years.

E. An electric kiln is a heating chamber used to transform materials.

F. Most manufacturers use whichever material is cheapest in their area.

G. Clay, when heated properly, becomes hard enough to form bowls and plates.

    Travis is the manager of G&G where he is responsible for forty employees (雇员)and profits (利润) of over $2 million per year. He's never late to work. He does not get upset on the job. When one of his employees started crying after a customer screamed at her, Travis took her away. "Your working uniform is your shelter," he told her. "Nothing anyone says will ever hurt you. You will always be as strong as you want to be."

    Travis picked up that lecture in one of his G&G training courses, an education program that began on his first day and continues throughout an employee's occupation. The training has, Travis says, changed his life. G&G has taught him how to live, how to focus, how to get to work on time, and how to master his emotions (情绪). Most importantly, it taught him willpower.

    At the center of that education is an extreme focus on an all-important habit; willpower. Dozens of cases show that willpower is the single most important habit for a person's success.

     And the best way to strengthen willpower is to make it into a habit. "Sometimes it looks like people with great self-control aren't working hard—but that's because they've made it automatic," Angela Duckworth, one of the University of Pennsylvania researchers said. "Their willpower occurs without them having to think about it."

     The company spent millions of dollars developing programs of study to train employees on self-control. Managers wrote workbooks that serve as guides to how to make willpower a habit in workers' lives. Those courses arc, in part, why G&G has grown from a sleepy company into a large one with more than seventeen thousand stores and profits of more than $10 billion a year.

    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.
