Anyone studying a foreign language knows the importance of memorizing words and expressions. {#blank#}1{#/blank#} We still also tell you ways about developing a large vocabulary.

    You have probably faced a situation in which you can't remember new words. Perhaps you haven't heard the word enough times or you haven't used it for a very long time. {#blank#}2{#/blank#}

    The easiest way to enlarge your vocabulary is to create flashcards. The word in English can appear on one side of the card. {#blank#}3{#/blank#} By repeatedly using flashcards, you can remember more words. The important point is that you should not try cramming (突击学习) unfamiliar words if you want to have long-term learning. This method can help students on some exams. But a couple of days later you're not going to remember any of that information. {#blank#}4{#/blank#} There are several websites that can help with testing. English learners can be helped by taking free language tests, which can be of great help to show you where you need to improve.

    {#blank#}5{#/blank#} However, with effort, a little sacrifice, and training, you can increase your number of vocabulary words.

A. You can also try using some free online tests.

B. Building a large vocabulary is not an easy task.

C. The difficulty in remembering and using words counts.

D. A large vocabulary improves our powers of expression.

    Most of us lead unhealthy lives; we spend far too much sitting down. If in addition we are careless about our diets, our bodies soon become loose and fatty and our systems slow moving.

    {#blank#}1{#/blank#}. I am thinking of such features of modern city life as pollution, noise, rushed meals and stress. But keeping fit is a way to reduce the effects of these evils. The usual suggestion to a person who is looking for a way to keep fit is to take up some sport or other. While it is true that every weekend you will find people playing football and hockey in the local park, they are outnumbered a hundred to one by the people who are simply watching them.

    For those who do not particularly enjoy competitive sports—{#blank#}2{#/blank#}—there are such separate activities as cycling, walking, jogging and swimming. What often happens though is that you do them in such a leisurely way, so slowly, that it is doubtful if you are doing yourself much good, except for the fact that you have at least managed to get up out of your armchair.

    Even after you have found a way for keeping in shape, through sport or gymnastics, {#blank#}3{#/blank#}, because, according to the experts, you must also master the art of complete mental and physical relaxation(放松). {#blank#}4{#/blank#}. Yoga, as practiced in the West, is the most widely known and popular of the systems for achieving the necessary state of relaxation. It seems ironical (讽刺性的), though, that as our lives have improved in a material sense we have found it increasingly necessary to go back to forms of activity—{#blank#}5{#/blank#}—which were the natural way of life of our forefathers.

A. be active and practise Yoga

B. There are some aspects of our unhealthy lives that we cannot avoid

C. and it is especially difficult to do so if you are not good at them

D. physical effort on the one hand and relaxation on the other

E. they spent most of the time out of doors

F. you are still only half way to good health

G. It has to do with deep breathing, emptying your mind of all thoughts, meditation, and so on

The Science of Risk-Seeking

    Sometimes we decide that a little unnecessary danger is worth it because when we weigh the risk and the reward, the risk seems worth taking. {#blank#}1{#/blank#} Some of us enjoy activities that would surprise and scare the rest of us. Why? Experts say it may have to do with how our brains work?

    The reason why any of us take any risks al all might have to do with early humans. Risk-takers were better at hunting, fighting, or exploring. {#blank#}2{#/blank#} As the quality of risk-taking was passed from one generation to the next, humans ended up with a sense of adventure and a tolerance for risk.

    So why aren't we all jumping out of airplanes then? Well, even 200,000 years ago, too much risk-taking could get one killed. A few daring survived, though, along with a few stay-in-the-cave types. As a result, humans developed a range of character types that still exists today. So maybe you love car racing, or maybe you hate it. {#blank#}3{#/blank#}

    No matter where you are on the risk-seeking range, scientists say that your willingness to take risks increases during your teenage years. {#blank#}4{#/blank#} To help you do that, your brain increases your hunger for new experiences. New experiences often mean taking some risks, so your brain raises your tolerance for risk as well.

    {#blank#}5{#/blank#} For the risk-seekers a part of the brain related to pleasure becomes active, while for the rest of us, a part of the brain related to fear becomes active.

As experts continue to study the science of risk-seeking, we'll continue to hit the mountains, the waves or the shallow end of the pool.

A. It all depends on your character.

B. Those are the risks you should jump to take.

C. Being better at those things meant a greater chance of survival.

D. Thus, these well-equipped people survived because they were the fittest.

E. This is when you start to move away from your family and into the bigger world.

F. However, we are not all using the same reference standard to weigh risks and rewards.

G. New brain research suggests our brains work differently when we face a nervous situation.

    Life is full of surprises and events that sometimes change one's daily routine. Some of them might be good and pleasant. {#blank#}1{#/blank#} For example, during an examination, you discover that you don't know the answers; one morning you are suddenly told that you get fired from your job. These unexpected events may cause anxiety and stress. So you need to find some ways to be less affected by them.

    {#blank#}2{#/blank#} Even if you live the same kind of life, doing the same things day after day, there could be unexpected events. So you need to realize that such events can't be avoided and you need to be prepared for them. In this way, you'll find it easier to deal with whatever happens in your life.

    Have a positive attitude. Not all unexpected events are bad. {#blank#}3{#/blank#} For example, even getting fired for work could finally turn out well, as you might find a more satisfying job.

    Introduce small changes into your life. {#blank#}4{#/blank#} You can try eating a different breakfast or drink tea in the morning instead of coffee, or do things that you usually do, but in a different way.

    Always focus on the present moment, learning from it and making use of new changes that come your way. In other words, make the most of the present moment, instead of thinking about what you lost, or how bad the situation is. {#blank#}5{#/blank#}

Life getting you down? Learn to bounce back

    "That which does not kill us makes us stronger.＂ Nietzsche said. There are a number of ways that can get us through tough times, help us to bounce back and make us happier. {#blank#}1{#/blank#}

    Find something you can control.

    {#blank#}2{#/blank#} But taking small, positive steps in any area of our life can have a ripple effect, enabling us to move forward in the problem area.

    {#blank#}3{#/blank#}

    As a species, we tend to focus on what's wrong rather than what's right. But we can benefit a lot from paying attention to what's going right. Psychologists have shown consciously focusing on these good things helps to increase our experience of positive emotions.

    Check your thinking.

    {#blank#}4{#/blank#}Leading psychologist Martin Seligman found that the way we interpret the causes of everyday setbacks can have a significant impact on our ability to cope and our physical health. He also showed we can learn more resilient(有弹性的) thinking styles.

    Distract yourself.

    When we are immersed in a problem, it is hard to think creatively about ways to deal with it. It often helps to take time out from the things you are worrying about.{#blank#}5{#/blank#}Not only does this give us a break from what we're doing and our worries, it's also great for our minds.

A. Always do something that is right.

B. It's true that there are lots of things we can't control.

C. An effective way of taking time out is exercise.

D. Next time you are feeling stressed or stuck, give them a try.

    Rivers play an important role on the earth, and we can't imagine what the earth would be like without rivers. {#blank#}1{#/blank#}

    With a length of 6, 650 kilometers, the Nile is the longest river in the world. The Nile River has been the source of human civilization since ancient times. The Nile has two main branches—the White Nile and the Blue Nile. The White Nile starts from the Great Lakes region of East and Central Africa through Lake Victoria. {#blank#}2{#/blank#} The Blue Nile carries with it a lot of fertile soil which turns out to be very important to farming in Egypt.

    The Amazon River is the world's largest river with a width of about 40 kilometers during the rainy seasons but about 10 kilometers wide when it is not flooded. The Amazon River has such a big water volume that it accounts for(占.....比例) more than 20% of all the world's fresh water—far more than any other river. {#blank#}3{#/blank#}The main Amazon River flows mostly through Brazil and Peru but its tributaries can also be found in many other countries.

    {#blank#}4{#/blank#}It has a depth of about 250 meters. Its length is 4, 700 kilometers. The sources of the Congo River are in the highlands and mountains in the Eastern Africa Rift Valley. It's the second largest river in terms of water volume. {#blank#}5{#/blank#}The Congo River basin(盆地) is the catchments(流域，集水区) area of the Congo River. It lies in both north and south of the Equator, making its flow very stable as there are always some tributaries experiencing a rainy season at any time.

B. The Congo River is the world's deepest river.

C. Do you know which is the deepest river in the world?

D. The Blue Nile originates from (发源于)Lake Tana in Ethiopia.

E. Without rivers, there would be no living life in and along them.

F. And it flows through the second largest rain-forests in the world.
