Along the river banks of the Amazon and the Orinoco there lives a bird that swims before it can fly, flies like a fat chicken, eats green leaves, has the stomach of a cow and has claws(爪)on its wings when young .They build their homes about 4.6m above the river ,an important feature(特征)for the safety of the young. It is called the hoatzin.

    In appearance, the birds of both sexes look very much alike with brown on the back and cream and red on the underside .The head is small, with a large set of feathers on the top, bright red eyes, and blue skin. Its nearest relatives are the common birds, cuckoos. Its most striking feature, though, is only found in the young.

    Baby hoatzins have a claw on the leading edge of each wing and another at the end of each wing tip .Using these four claws ,together with the beak(喙),they can climb about in the bushes, looking very much like primitive birds must have done. When the young hoatzins have learned to fly, they lose their claws.

    During the drier months between December and March hoatzins fly about the forest in groups of 20 to 30 birds, but in April, when the rainy season begins, they collect together in smaller living units of two to seven birds for producing purposes.

    We can achieve knowledge either actively or passively. We achieve it actively by direct experience, by testing and proving an idea, or by reasoning.

    We achieve knowledge passively by being told by someone else. Most of the learning that takes place in the classroom and the kind that happens when we watch TV or read newspapers or magazines is passive. Conditioned as we are to passive learning, it's not surprising that we depend on it in our everyday communication with friends and co-workers.

    Unfortunately, passive learning has a serious problem. It makes us tend to accept what we are told even when it is little more than hearsay (传闻) and rumor.

    Did you ever play the game Rumor? It begins when one person writes down a message but doesn't show it to anyone. Then the person whispers it, word for word, to another person. Thai person, in turn, whispers it to still another, and so on, through all the people playing the game. The last person writes down the message word for word as he or she hears it. Then the two written statements arc compared. Typically, the original message has changed.

    That's what happens in daily life. The simple fact that people repeat a story in their own words changes the story. Then, too, most people listen imperfectly. And many enjoy adding their own creative touch to a story, trying to improve on it, stamping it with their own personal style. Yet those who hear it think they know.

    This process is also found among scholars and authors: A statement of opinion by one writer may be restated as fact by another, who may in turn be quoted by yet another; and this process may continue, unless it occurs to someone to question the facts on which the original writer based his opinion or to challenge the interpretation he placed upon those facts.

    After four silent years, British singer Adele Adkins finally introduced herself to the world again with Hello, the opening song from her third album 25, which came out on Nov. 20, 2015.

    Although Adele is a very successful singer now, music wasn't always what she saw herself doing. At age 10, when she saw her grandmother's pain over the death of Adele's grandfather, she pictured herself as a heart surgeon.

     “I wanted to fix people's hearts,” she told the UK music website i-D, remembering the childhood interest she'd had in biology classes until she found out that her real talent was for singing.

    “Adele didn't go to medical school, but many would agree that she still has healing (治愈)powers. Her songs find the kind of memory every listener holds somewhere in their heart. This kind of feeling is what people have always liked in Adele,” said The Telegraph. “She writes a pop diary, sharing the simple secrets of her heart.”

    Most successful pop stars make albums at a fast pace, but not Adele. After her second album 21 won the 2012 Grammy Award for Album of the Year, she made it clear with her label that she would spend “four or five years” making her next album. She told magazine. “I won't come out with new music until it's better than 21.”

    Instead of seeking fame, Adele remained silent and moved to the countryside. In her free time, she loved to watch TV series Teen Mom, American Horror Story, and The Walking Dead.

    Living life as normally as possible is important to the singer's art. “Nobody wants to listen to a record from someone who's not living in the real world,” Adele told i-D.“So I live a low-key life for my fans.”

    Whether in your life or work, the following things are not the reasons for you to feel embarrassed. It's OK and just move on.

⒈Mistakes while learning

    There will be times when you have people above you(a boss) or even next to you(a coworker) that will get really annoyed with you for“ruining"  something "important".{#blank#}1{#/blank#} Even if you make mistakes and get a punishment, persevere and push on. You do not need to be embarrassed for learning from your mistakes.

⒉Food choices

    People are different and have different taste buds（味蕾）.Whether it is healthy or not, food is a choice and it is part of life.{#blank#}2{#/blank#}  You do not need to be embarrassed for food you do or do not like. Tell them, "It is a personal choice I have made, and I am committed to it.”

⒊Your past

    Allowing positive experiences to define, limit, improve, and outshine（凸显）you may cause you to be caught up in the past and unable to truly live in the present. Whether your history is positive, negative, or somewhere in between, don't hold on to the negative experiences and let it reflect your current behavior，{#blank#}3{#/blank#}

⒋The clean lines of your car／home／workspace

    When everyone gets in the car, you realize your Starbuck bags are still on the floor. So what? Think about it this way: everyone has a "messy" aspect of their life. Maybe their home is completely clean, but the relationship with their spouse（配偶）is messy. Someone's car gets washed once a week, but his/her work life could use some help.{#blank#}4{#/blank#} We don't apologize to others about our personal limitations. By being outwardly embarrassed, it only brings more attention to the fact!

⒌Putting yourself first

    If you find yourself saying no to something or making up lies to get out of it,tell them the truth,  and don't apologize. You will feel much better in the long run if you are honest with them and yourself. If you're not up to a voluntary duty, you don't have to be. You can politely refuse the person's request.

    {#blank#}5{#/blank#} Put yourself first.

A. It is simply a personal choice that people make for their own reasons.

B. It is okay to be selfish from time to time.

C. Errors are bound to happen when you have on your training wheels.

D. Each of them waits for your immediate help.

E. Let bygones(过去的事)  be bygones.

F. Forgetting history means betrayal.

G. No one on Earth lives a perfectly "clean" life in every aspect.

Signs of Healthy Friendships

Once in a while it's helpful to see if your friendship is as healthy as it can be. You might get used to a friendship over time to the point where you don't see the room for improvement. And since great friendships are priceless, you should always surround yourself with the kind of people who will lift your spirits, make you laugh, and remind (提醒) you that you are loved. {#blank#}1{#/blank#} Here are characteristics (特征) that strong friendships share.

{#blank#}2{#/blank#}

Friends make you feel comfortable with yourself, so you don't need to act like someone you're not. Your friends know your shortcomings and love you anyway. You are perhaps the "best version" of yourself when you're with your friends.

A healthy friendship includes plenty of gentle honesty. True friends won't pretend just to avoid an argument (争论). {#blank#}3{#/blank#} As a result, you'll know where you stand with your friends and won't be afraid to share your true opinions.

They argue in a healthy way.

One of the biggest misunderstandings about good friends is that they never fight. But let's face it everyone fights. {#blank#}4{#/blank#} In fact, voicing your opinions freely will cause you to disagree from time to time and that's okay.

Healthy friendships mean you can be friends with someone else, too.

{#blank#}5{#/blank#} That's why great friends will improve your relationship yet still encourage you to meet people and try new things without them. A healthy friendship means that sometimes the two of you spend time apart, and that's okay.

A. Arguing isn't unhealthy.

B. Is your friendship as healthy as it can be?

C. Good friends dine out together from time to time.

D. Good friends are real and honest with each other.

E. With an unhealthy friendship, you know clearly that something is "off".

F. Even if you have the best friend, it doesn't hurt to expand your social circle.

G. In a positive friendship, your friends won't lie to you, and they won't hurt your feelings either.
