Animals are humans' best friends. Here we will know about some of those interesting friends.
       Gouldian Finch

Native to Australia, the Gouldian finch has special green, yellow, red and black markings. For the males (雄性), the part between the neck and the stomach is bright purple, while for females, this part is pale purple. We all Have to agree that nature has created some really great animals with the smallest of details.

Keel-Billed Toucan

It is the very same crazy bird from the movie Rio, also known to be the "rainbow billed toucan". The bird has a black body and a yellow face. The color of its bill (喙) is a combination of green, yellow, orange and red, and that's how the name rainbow billed toucan came from. It is rarely seen alone. It travels in small groups of about six to twelve individuals.

The Oriental Dwarf Kingfisher

It is a great tiny bird commonly found in South Asia. This bird is the most brightly colored and the smallest kingfisher species. Its special feature is the orange with bluish-purple head, which can be easily recognized. The throat is white with bright orange colored lines at the bottom. It is a pretty and small bird.

Poison (毒) Dart Frog

It is a kind of very beautiful creature. The bright colors of the poison dart frog send a warning to its natural enemies about its poison. Found in South America, with some of the brightest shades of yellow, copper, red, green and blue, this frog is among those very animals that you have to watch out in the Amazon Rainforest.

I love hiking. In the mountains, the birds sing for me; the various trees and flowers overwhelm (征服) my eyes and the deep blue of the sky inspires me and makes me feel calm. Furthermore, I can breathe the fresh air, keeping away from the dust and pollution of the city. It seems that all my senses are awakened when I am in the mountains. More importantly, hiking teaches me a lot.

I have been a traveler since childhood and was drawn towards mountains and their beauty. Later my reading several travel books made me think if I could also go on such journeys. Finally, I decided to give it a try. After I was well-prepared to face all difficulties of the hike, I joined a group of hikers. On the way, we encouraged each other, took beautiful pictures, and sat down now and then to feel the breath of the land. All my worries disappeared and we talked and laughed just like kids. This journey excited me for a long time.

I never actually realized the need for water until I started hiking. I remember once I was on a hike where our water was not enough. It was a night hike and the next day we had to return back to our base camp following the same route. So we have to save it for emergencies (紧急事件).That day I exactly learned water is of great value and that we have a duty to save it.

Besides enjoying the beautiful natural views, you have to go out of your comfort zone and push yourself hard to challenge your normal limits when hiking. On a hike, you may sometimes get injured but you can't stop until you reach the destination. Every next try will surely make you stronger and happier if you embrace (拥抱) your injuries, pains and discomforts.

Sometimes we may have a conversation with those locals living in wooden houses. You know, mountain life is hard and difficult. But they never complain about their life. They are happy with what they have. Many times they are facing extreme weather and they just fight with them. They are so brave. What can we complain about?

A kind of blue dye (颜料) called folium had been widely used to paint pictures on the pages of manuscripts (手稿) created in the Middle Ages. But long ago, this watercolor fell out of use.

"Manuscripts are an important part of the cultural works of art in the Middle Ages," said scientist Maria in an email to CNN. "Color is a basic feature of these manuscripts. To let ancient manuscripts. keep a good condition for future generations, we sometimes need to repaint their inside pictures through the ancient dye — like folium — that was once used in these manuscripts. But everyone who knew how to prepare folium had died long ago. So 'I led a team to study this dye."

Her team turned to books from the 1400s and found one that described the plant that was its source. It is a tiny plant with silvery-green leaves. Days later, the scientists reached a village in south Portugal, where nobody knew this little plant. However, after carefully going through a plenty of different plants growing there, the scientists finally raked out the plant they wanted and brought some back to their laboratory.

Back in the lab, the scientists produced the dye with the help of an ancient text on colors. The text has clearly described the ways to make it. "It's cool to have done that work of looking in the historical records and traveling back in time," says Casadio, who was not part of this study. It recreates an ancient process. By making the dye, the scientists could study its chemistry without experimenting on priceless delicate (易损的)  works of art, she points out.

Now, the researchers don't know the dye's stability(稳定性)and its ability against the environment that may wear and break it down over time. "To know such information is necessary if we desire to make these colors last long enough," Maria said. "So our study will continue."

Recess (课间休息) time has been dropping for many children in America. This drop began the same year the No Child Left Behind Act (NCLB) was passed. The law aimed to make American education system more internationally competitive by introducing achievement goals for schools. And the goals are gauged (评定) by standardized tests in reading and math. If schools missed their achievement goals, they could be in trouble, including loss of funding.

It's no surprise that teachers have felt the pressure to make sure students perform well on standardized tests. When educators are facing pay cuts, loss of funding to their school and perhaps even the loss of their jobs, it's no wonder that they started questioning if recess was a waste of time. This pressure to bring even more learning into the school day is especially felt by underperforming, low-income schools that are already short of funding.

It may seem strange to send kids out to play when they're falling below state standards, but getting outside for unstructured (散乱的) play may be more helpful than keeping kids in the classroom all day.

"Moving, running and playing outdoors freely have great influence on children. These activities play a role in children's abilities to focus and control themselves throughout the day," Marie Conti says, a famous educator of early childhood education. The mind cannot be educated without using the body. Learning is a whole of thinking and moving," she added.

Recess time makes it possible for children to learn something they can't get in class. Asking other kids to play, explaining the rules of a complex game and ending arguments are all important life lessons that children can only learn if they're given time to play. When something unhappy happens, children can find a way to get back to having fun themselves.

The physical activities kids take part in during recess can also reduce stress levels and allow children to feel more relaxed. In an education system that. Continues to place higher expectations on children to perform to a certain standard, less stress is just what the doctor ordered.

When buying a backpack, there are several things you should consider. A backpack used for carrying school supplies, for example, may not need to have as many features as a backpack that is to be used for hiking or camping.

When buying a backpack，look for one that can easily be placed on your back. Many people carry their backpacks over only one shoulder.Backpacks are designed to be carried completely on your back, supported by both shoulders, in order to help evenly distribute (分配) the weight. In fact, carrying a backpack that is either too heavy or used improperly is one of the leading causes of back injuries in students.

 If the backpack will be used for carrying textbooks, it must be wide enough to contain the width of the books it will carry. If the backpack is for hiking, it needs to be large enough to carry supplies such as a solar blanket and other camping things.

Another consideration when buying a backpack is the number of compartments (隔层) the backpack has. When used for hiking or camping, it's often helpful for a backpack to have several smaller compartments.

The material is also important when buying a backpack. When buying a backpack for hiking or camping, it is best to buy one that is strong enough.  If you are buying a backpack for college use, it might also help prevent your books and homework from getting wet while you are walking from one building on campus to another in the rain.

A. But this is actually a mistake.

B. There are backpacks different from traditional ones.

C. It is helpful to buy a backpack with much space inside.

D. It is important to buy one that will be comfortable to carry.

E. This way, important items such as knives are easy to reach.

F. Thus, your clothing or supplies will not get damaged in bad weather.

G. The most important consideration when buying a backpack is its future use.

Karen Loewe has been teaching seventh and eighth grade students for 22 years, 1 her most recent day was apparently the most 2 day of her educational career — she tried a new activity with her students in her class.

3establishing that her classroom was a safe space for 4, she asked her students to write about some emotional problems. Since they weren't required to put their names on the paper, they could describe their issues as 5as they wanted. The youngsters were then asked to take turns 6 what their classmates wrote, and all of them were given the opportunity to identify (表明）themselves as the person 7 for the writing. "Things like being left by their parents, death and  8 pets were written down. The kids who heard the. stories would cry because what they were hearing was 9 It was a difficult day, but I believe my kids will judge a little less, 10 a little more, and forgive a little faster," Loewe said.

Since she wrote about her 11 on social media, her post has been shared more than 500,000 times. 12 from all over the world have reached out to her about using similar activities in their own classrooms and her students have learned to 13 other people. "They don't casually 14 or talk down to each other anymore," she said. "They're not rude. It has completely 15 how they treat each other. I wish I would have done this years ago."

Many cities have live music in their parks during the summer. But there's a park in Denmark

 people can hear music all year round — not on a stage but among the trees.

As part of art project for public in Aalborg, trees in the Park of Music host the music once  (perform) by musicians at the nearby cultural center. It all started in the 1980s when the city asked visiting musicians to plant a tree a memorial (纪念物) of their excellent and (forget) performances.

Since then, over 80 trees (plant) by musicians worldwide. In 2012, some of the trees became playable! It works like this.  (simple) press the button (按钮）on the plaque (匾牌)bearing a musician's name next to the tree, and people  (hear)a piece of the musician's music.

All kinds of music from  (artist) like Sting can be heard. The trees are "played" about 300,000 times a year, (show) the popularity of the art project.

December 16, 2009 was the worst day of my mother's life. It was on that day that she was told her thirty-six-year-old daughter had developed breast cancer. I would never forget her hopeless expression and tear-filled eyes as I told her. That scene uncontrollably broke my heart. It was one of the few times in my life that I had seen my mother was so painful and weak.

Since I got breast cancer, the doctors had made a heavy-duty plan to fight with it, which would mean an operation on my breast, five months of chemotherapy (化疗), and five weeks of radiation therapy. It also meant that an independent single girl who lived alone was in serious need of some help and care.

Thankfully, I was blessed with my own army of family, friends and co-workers who had offered to help me out with whatever I might need, including meals and rides to doctors' appointments. But as grateful as I was, there really was only one person who I wanted by my side — my mom. Despite living 300 miles away, my mother agreed even without a second thought. She was going to be my primary caregiver, driver, personal cook, nurse, counselor, and shoulder to cry on. No one else in the world could fill her shoes. It was a job that only she could do.

The night after my first chemotherapy treatment was firmly fixed in my memory. I was never so sick in my entire life. I couldn't even keep down a glass of water. And after hours spent in the bathroom, I weakly lifted myself into bed, weeping, "Please, God, take this away from me. Please make me fed better." At that moment, my mother crawled into bed with me and wrapped her entire body around me. It looked as if l had still been a little girl.

Paragraph 1:

Over the next six months, my mom traveled between two homes just to take care of me.

Paragraph 2:

However, when I finally began to recover, my morn suddenly fell ill.
