Every living thing has genes. Genes carry information. {#blank#}1{#/blank#} They make sure that humans give birth to humans and cows give birth to cows. They also make sure that a dog doesn't give birth to a frog, or an elephant to a horse. However, genetic engineers take genes from one species-for example, a snake, and transfer them to another-for example, corn. {#blank#}2{#/blank#} Such new life forms have been described, by some scientists as a real-life Frankenstein(科幻怪人).

    Genetic engineers put duck genes into chicken to make the chickens bigger. They put hormones(激素) into cows to make them produce more milk. They put genes from flowers into beans and from fish into tomatoes. {#blank#}3{#/blank#} It just makes them easier and faster for the farmer to grow.

    The effects of genetic engineering on the natural world may be disastrous. The engineers may create strange life beings, or monsters. that we cannot control. {#blank#}4{#/blank#} They'll have to find one, fight for one-or kill for one. It may be your land they fight for-or you that they kill. Moreover, the effects of these experiments can often be cruel. In America, pigs were given human genes to make them bigger and less fatty. The experiment failed. The pigs became very ill and began to lose their eyesight. We would all like a better, healthier and longer life, and genetic engineering might give us this. On the other hand, it may be a dangerous experiment with nature. In the story of Frankenstein, the doctor created such a terrible and dangerous monster that he had to destroy it. {#blank#}5{#/blank#}

A. The information tells us what to do or what not to do

B. We must make sure that this tale remains a story-and no more than that

C. This doesn't make them cheaper, tastier, or healthier

D. The new life forms have no natural habitat or home

E. Then they feed the tomatoes to the fish

F. In this way a new life form is created

G. They are passed on from generation to generation

    Many people believe that there is some truth in the saying Laughter is the best medicine.{#blank#}1{#/blank#} Laughter helps relieve pain, strengthen the immune system and reduce stress. Laughter stimulates(激发) hormones which make us feel happy. Laughter also increases the flow of blood throughout the body and has benefits which are similar to the ones you get by doing exercise.

    {#blank#}2{#/blank#}Children exposed to funny films and cartoons before major medical procedures are able to cope better with pain and anxiety.{#blank#}3{#/blank#} These are professional clowns who are sent to hospitals and wards to entertain and distract sick children.

    Laughter therapy has become very popular in recent years and as a result, more and more laughter clubs are starting to open up in cities and towns all over the world. At a laughter session, a trained therapist instructs the group to perform a series of exercises which are designed to produce laughter. {#blank#}4{#/blank#}And it takes them some time to get rid of their inhibitions(心理抑制).They might even start off with fake laughter, but this doesn't matter because our bodies can't tell the difference, and the results are the same. Moreover, laughter is contagious(传染的).{#blank#}5{#/blank#}

    So next time you feel ill, stressed out or depressed, try watching a funny film or try remembering an amusing incident in your life. You will soon feel better.

A. If one person starts giggling, it is unavoidable that everyone else will be drawn in.

B. Laughter helps you focus.

C. This finding has led to so-called clown doctors.

D. In fact, research done by scientists has shown that laughter has a lot of health benefits.

E. Laughter makes the world a better and more colorful place.

F. Some people may find the idea embarrassing at first.

G. Using laughter therapy in children's hospitals has proven to be invaluable.

Winning an Oscar isn't all about acting ability

    While the awards claim they recognize the top performances from around the world, a new study has found that you're more likely to win an Oscar if you're an American acting in a film that portrays American culture.{#blank#}1{#/blank#}British actors are more likely to take home an award.

    Researchers say the trend suggests viewers are more likely to perceive a performance as "truly brilliant" if they are members of the same social group as the actor. It can be seen, perhaps most famously, in the case of Leonardo DiCaprio, who finally won a long-awaited Oscar in the 88th Academy Awards for his role in The Revenant, which follows the story of an American frontiersman.{#blank#}2{#/blank#}In 2014, Matthew McConaughey won an Oscar for his role in Dallas Buyers Club, and Jennifer Lawrence took an award home in 2013 for Silver Linings Playbook{#blank#}3{#/blank#}The findings come from a new study published in the British Journal of Psychology. The team investigated a total of 908 merit prize winners: 97 winners and 383 nominees for the Oscars, and 97 winners and 331 nominees for the BAFTAs. Overall, they found that US actors dominated the awards, claiming over 50 percent of the prizes across the Oscars and BAFTAs.

    {#blank#}4{#/blank#}When the performer and judge shared membership within a particular social group-for example, being American-the actor was more likely to win. As a result, American actors were found to win 52 percent of all BAFTAs, and 69 percent of all Oscars. While British actors won just 18 percent of all Oscars, and 34 percent of BAFTAs.

    {#blank#}5{#/blank#}In the Oscars, Americans who performed in films about non-US culture accounted for just 26 percent of the award winners. But, those who performed in films about American culture made up 88 percent of the winners.

A. In recent years, many actors have cast themselves as frontiersmen.

B. Subject matter played a role, too, according to the researchers.

C. And, the same applies to London's BAFTAs.

D. But they also noted a trend within social groups.

E. But the trend also stretches back throughout the years.

F. Things are different in Britain.

G. Daniel Day-Lewis won an Oscar in 2008 for his role in There Will be Blood.

    Multitasking-doing several things at a time-was once applauded as the best way to work. But does it actually help you get things done, or does it make you less effective?

    {#blank#}1{#/blank#}If you can actually do two or more things at one time, that clearly saves time.{#blank#}2{#/blank#}And it can fill time that would otherwise he spent poorly.

    However, a growing body of research shows that multitasking is not as productive as it appears. It turns out that when most people multitask, they don't actually focus on more than one thing at a time.{#blank#}3{#/blank#}But changing your focus constantly uses mental energy that could he spent working. It also causes you to take longer and make more mistakes. In addition, it creates stress. People who try to multitask often end up feeling more anxious and less peaceful than people who don't.

    {#blank#}4{#/blank#}A very small group of people-about two percent of the population-excel at multitasking. These people, called supertaskers, are able to work on several things at once without their performance suffering. But experts caution: supertaskers are very rare. The majority of people who think multitasking makes them more productive are fooling themselves.

    If you do want to multitask, productivity experts recommend doing it carefully.{#blank#}5{#/blank#}

A. There are some exceptions to the no-multitasking vile.

B. Instead they switch back and forth between concentrating on two or more tasks.

C. Doing things one at a time usually helps people produce better work.

D. To some people, the advantages of multitasking seem obvious.

E. Multitasking actually works against the goal of getting things done.

F. It might also make you feel productive, which can in turn make you happy.

G. Pair a mentally challenging task with a physical task you don't have to think about.

Before there was the written word, there was the language of dance. Dance expresses love and hate, joy and sorrow, life and death, and everything else in between.

{#blank#}1{#/blank#}We dance from Florida to Alaska, from north to south and sea to sea. We dance at weddings, birthdays, office parties and just to fill the time.

"I adore dancing," says Lester Bridges, the owner of a dance studio in Iowa. "I can't imagine doing anything else with my life." Bridges runs dance classes for all ages. "Teaching dance is wonderful. {#blank#}2{#/blank#}It's great to watch them. For many of them, it's a way of meeting people and having a social life."

{#blank#}3{#/blank#}"I can tell you about one young couple," says Bridges. "They're learning to do traditional dances. They arrive at the class in low spirits and they leave with a smile. {#blank#}4{#/blank#}"

So, do we dance in order to make ourselves feel better, calmer, healthier? Andrea Hillier says, "Dance, like the pattern of a beating heart, is life. Even after all these years, I want to get better and better.{#blank#}5{#/blank#} I find it hard to stop! Dancing reminds me I'm alive."

A. So why do we dance?

B. Dance in the U.S. is everywhere.

C. If you like dancing outdoors, come to America.

D. My older students say it makes them feel young.

E. I keep practicing even when I'm extremely tired.

F. Dancing seems to change their feeling completely.

G. They stayed up all night long singing and dancing.

How to make Quick Decisions For Your Life

We make decisions every day. {#blank#}1{#/blank#}When it comes to making decisions, choosing the right one can at times be stressful, especially if the decision must be made quickly. Indecision often weighs us down, but there are some useful tips for making quick decisions more easily.

{#blank#}2{#/blank#} Sometimes the key to making a quick decision comes down to planning ahead of time for just such an occasion. We all know we're going to come to an important decision-making point sooner or later, so having a plan already in hand can put our mind at ease when that time comes.

Overcome fear. {#blank#}3{#/blank#} While it may seem difficult to overcome the fear of making the wrong choice, many experts agree that we shouldn't be afraid to make the wrong decision, even if it seems important. The vast majority of wrong decisions can be corrected, while delaying decisions can often lead to more problems.

Write down all the advantages and disadvantages of your decision. Even if you don't have all the information, writing down all the pros and cons (优缺点) is a good starting point for figuring out what to do. In cases where there simply isn't enough time to write things down, make a mental list in your mind. Thinking of the pros and cons can help you organize your thoughts. {#blank#}4{#/blank#}.

Determine criteria. Remember that every decision you make should come with a certain list of criteria. {#blank#}5{#/blank#} But once you know the requirements you're looking for, making a decision will become easier. Look for the choice that satisfies the list you've made, and once that choice is found, you should move ahead with it.

A. Have a plan.

B. The list may be short or quite long.

C. Communicate your decision with others.

D. And this can always lead to a clear answer.

E. So cut out any options that you know you will not choose.

F. Often, one thing that keeps us from making decisions is fear.

G. Some can be very important while others are not serious in the long run.
