Why do we go to zoos? Millions of people around the world visit zoos each year, but the reason is hard to explain .{#blank#}1{#/blank#} But the animals they see in zoos are little like the toys, cartoons, and decorations that fill their homes. For such children, meeting with real animals can be confusing, even upsetting.

    The great interest that children have in animals today might lead one to suppose that this has always been the case. {#blank#}2{#/blank#}That was also when zoos became an important part of middle-class life.

    {#blank#}3{#/blank#}They lived together with our ancestors in a shared natural environment. In the Industrial Era, the human domination (支配)of animals could be seen in the popularity of real-looking animal toys. Children rode rocking-horses that had realistic features, and they slept with bears, tigers, and rabbits that looked and felt almost real. The Twentieth Century marked a further development--the change of animals into people.

    This was the age of Babar the Elephant, Hello Kitty, and the Lion King. Parents and children had previously wanted animals that looked like animals.{#blank#}4{#/blank#}.

    In a zoo they hope to see the living breathing versions of their character friends. They find instead unfamiliar creatures who cannot speak, smile, or interact with them. For this reason, a visit to the zoo can be disappointing for children today.{#blank#}5{#/blank#} Meeting real animals reminds us forcefully of the boundary between imagination and reality.

    When we visit animals in a zoo, perhaps we will recall our true relationship not only to animals but to the entire world.

A. Animals are the best friends of the human beings.

B. Most of children are looking forward to visiting zoos.

C. Perhaps that disappointment is the best gift a zoo can offer.

D. But now they want animals that look and act like humans

E. Yet, it was not until the Industrial Era that animals became part of childhood.

F. In prehistoric times, there had been no zoos, as animals were a real part of the human world.

G. Many of those visitors are children, whose lives are already surrounded by animals' images.

    Today is a perfect day that can leave you with good memories you may someday share with your friends. Here's how:

    {#blank#}1{#/blank#} You can see or do something a million times, but you can only see or do it for the first time once. As a result, first time experiences usually leave a deep mark in our minds for the rest of our lives. So try to experience something different and you'll have more memories.

    Work on something that's great to you.{#blank#}2{#/blank#} Life is short. Today is the day to take action. Smile and notice what's right. Everything that happens in life is neither good nor bad.{#blank#}3{#/blank#} And no matter how it turns out, it always ends up just the way it should. Either you succeed or you learn something.

    Be true to yourself. The only shoes you can wear are your own. If you aren't being yourself. You aren't truly living.{#blank#}4{#/blank#}

    Make a new friend. People are interesting creatures, and no two people arc exactly alike.{#blank#}5{#/blank#}Find out what makes them different. They'll likely open your eyes to wonderful ideas. And you never know, they just might change your life.

Be present. Be here now. Remember, right now is the only dear moment to you. Right now is life. Don't miss it.

A. Learn a new skill.

B. Try something new.

C. It just depends on your opinion.

D. So meet someone new today.

E. And in fact, you're only existing.

F. Pay close attention to what you're doing.

G. Make yourself busy with something meaningful.

    Eyesight plays a very important role in our daily life. Every waking moment, the eyes are working to see the world around us. Over forty percent of Americans worry about losing eyesight, but it's easy to include steps into our daily life to ensure healthy eyes. Here are five suggestions for a lifetime of healthy eyesight:

    Schedule yearly exams. {#blank#}1{#/blank#}Experts advise parents to bring babies 6 to 12 months of age to the doctor for a careful check. The good news is that millions of children now can have yearly eye exams and following treatment, including eye- glasses.

    Protect against UV rays . Long-term stay in the sun creates risk to your eyes. No matter what the season is, it's extremely important to wear sunglasses. {#blank#}2{#/blank#}

    Give your eyes a break. Two-thirds of Americans spend up to seven hours a day using computers or other digital products. {#blank#}3{#/blank#}Experts recommend that people practice the 20/20/20 rule: every 20 minutes, take a 20-second break and look at something 20 feet away.

    {#blank#}4{#/blank#}As part of a healthy diet, eat more fruits and vegetables each day. Vitamins C and E help protect eyesight and promote eye health.

    Practice safe wear and care of contact lenses (隐形眼镜). Many Americans use contact lenses to improve their eyesight. While some follow the medical guidance for wearing contact lenses, many are breaking the rules and putting their eyesight at risk. {#blank#}5{#/blank#} Otherwise, you may have problems such as red eyes, pain in the eyes, or a more serious condition.

注意：每空一词。

    A recent study points out a so-called “gender-equality paradox(性别平等悖论)”: there are more women in STEM (science, technology, engineering, mathematics) in countries with lower gender equality. Why do women make up 40 percent of engineering majors in Jordan, but only 34 percent in Sweden and 19 percent in the U.S.? The researchers suggest that women are just less interested in STEM, and when liberal Western countries let them choose freely, they freely choose different fields.

    We disagree.

    From cradle to classroom, a wealth of research shows that the environment has a major influence on girls' interest and ability in math and science. Early in school, teachers, unconscious prejudice push girls away from STEM. By their preteen years, girls outperform boys in science class and report equal interest in the subject, but parents think that science is harder and less interesting for their daughters than their sons, and these misunderstandings predict their children's career choices.

    Later in life, women get less credit than men for the same math performance. When female STEM majors write to potential PhD advisors, they are less likely to get a response. When STEM professors review applications for research positions, they are less likely to hire “Jennifer” than “John,” even when both applications are otherwise identical—and if they do hire “Jennifer,” they pay her $4,000 less.

    These findings make it clear that women in Western countries are not freely expressing their lack of “interest” in STEM. In fact, cultural attitudes and discrimination are shaping women's interests in a way that is anything but free, even in otherwise free countries.

    “Gender-equality paradox” research misses those social factors because it relies on a broad measure of equality called the Gender Gap Index (GGI), which tracks indicators such as wage difference, government representation and health outcomes. These are important markers of progress, but if we want to explain something as complicated as gender representation in STEM, we have to look into people's heads.

    Fortunately, we have ways to do that. The Implicit Association Test (IAT) is a well-validated tool for measuring how tightly two concepts are tied together in people's minds. The psychologist Brian Nosek and his colleagues analyzed over 500,000 responses to a version of the IAT that measures mental associations between men/women and science, and compared results from 34 countries. Across the world, people associated science more strongly with men than with women.

    But surprisingly, these gendered associations were stronger in supposedly egalitarian (主张平等的) Sweden than they were in the U.S., and the most pro-female scores came from Jordan. We re-analyzed the study's data and found that the GGI's assessment of overall gender equality of a country has nothing to do with that country's scores on the science IAT.

    That means the GGI fails to account for cultural attitudes toward women in science and the complicated mix of history and culture that forms those attitudes.

Little Habits Make a Big Difference

Everything around us is changing at amazing speed, it seems ̶ but some things will always remain the same.{#blank#}1{#/blank#} Some of our daily habits have the power to always give us happiness and lead us toward success. Here are some little habits that can make a big difference:

    {#blank#}2{#/blank#}

    Many studies have linked early rising with success. An early morning wake-up carries benefits including better planning and anticipation（预料）of problems, and more time to do the things that make you happy.

    Happiness comes to those who are curious.

    {#blank#}3{#/blank#} As long as you live, there will always be something to learn, and as long as you follow your heart and your passions, you won't miss out on learning.

    Believe in yourself and all that your are.

    {#blank#}4{#/blank#} Confidence is the key to success ̶ the thing that lets you look at the past without regret, stay grounded in the present, and prepare for the future without fear.

A day well spent gets you a good night sleep.

    Enough sleep makes you feel healthier and happier, and it's more than lifting up your mood or removing exhaustion. Adequate sleep is a key part of your health and inner happiness. {#blank#}5{#/blank#}

    It doesn't take a huge effort to make a significant change in your life－using one or two tiny habits may be all you need. Get started today and you'll soon be experiencing the rewards.

A. That's why habits are so powerful.

B. The ground work of all happiness is good health.

C. Early to rise makes you healthy, wealthy, and wise.

D. The habit of respect means treating everyone with kindness.

E. Nothing will ever make you happier than having faith in yourself.

F. When you rest better, you can live better and achieve more happiness.

G. There is no stage in life when we can't be learning something valuable.

How to Overcome Challenges in Your Life

    We all face tough and difficult challenges in life. To overcome challenges you need to have that "never quit" attitude in life. If you develop it, you'll overcome quite a bit.

    Motivate yourself. Say "YES, I CAN." The challenge should bring out the best of you in this situation. Slow it down, and think that process through.{#blank#}1{#/blank#} If you develop that mindset(心态), you'll get it done.

    Stay calm and cool­headed. Remain calm when you're facing serious troubles and problems in life. You have to recollect yourself, and calm down. You can't solve problems when you're panicking. Take a deep breath, relax, and slow it down. Think things through calmly.

    Let failure and fear fuel you in a positive way. Everyone fails at times. If you fail the first, second, or third time, don't give up.{#blank#}2{#/blank#}

    Learn what made you fail and overcome these challenges. Simplify the challenge you're facing. Make the challenge easier than it is. Start by breaking it down into steps. As you get through each step, you develop more confidence and you believe you can get it done, and then you will overcome them.

    {#blank#}3{#/blank#} To overcome a challenge, you have to believe you can really do it. You have to find out all the ways you can use to overcome it, and put them to full use with all your effort. It's our own mental stability that's the difficult part. When you do it mentally, you'll actually be able to do it.

A. Stay positive and confident.

B. Most people will avoid any challenge, because they're scared of failing.

C. Develop that confidence in saying there's no way you're going to fail at this.

D. Pick yourself up, and learn from why you've failed, and move on in a positive direction.
