Climate change is not only a human problem; animals have to adap t to it as well. Some" warm-blooded" animals are shapeshifting(变形) and getting larger legs, ears, and beaks to bettercontrol their body temperatures as the planet gets hotter. Bird researcher Sara Ryding of Deakin Universityin Australia describes these changes in a review.

"It's high time we recognized that animals also have to adapt to these changes, and this is occurringover a far shorter time than would have occurred through most of evolutionary time," says Ryding. "Theclimate change that we have created is putting a lot of pressure on them, and while some species willadapt, others will not."

Ryding notes that climate change is a complex phenomenon that's been occurring gradually, so it'sdifficult to determine just one cause of the shapeshifting. But these changes have been occurring acrosswide geographical regions and among a variety of species, so there is little in common apart from climatechange.

Strong shapeshifting has particularly been reported in birds. Several. species of Australian parrot haveshown, on average, a 4% to 10% increase in size since 1871, and this is positively associated with thesummer temperature each year. North American dark-eyed juncos, a type of small songbird, had a linkbetween increased size and short-term temperature extremes in cold environments. There have also beenreported changes in mammalian(哺乳动物) species. Researchers have reported tail length increases inwood mice."The increases in appendage(附肢) size we see so far are quite small ——less than 10% so the changes are unlikely to be immediately noticeable,"says Ryding."However, prominent(突起的)appendages such as ears are predicted to increase."

Next, Ryding intends to investigate shapeshifting in Australian birds by 3D scanning museum birdsamples from the past 100 years. Undoubtedly, it will give her team a better understanding of which birdsare changing appendage size due to climate change and why.

Andrea Lankford quit her job after spending 12 years as a National Park Service forester specializingin search and rescue missions in scenic and remote American landscapes. However, decades later, threeyoung hikers went missing on the Pacific Crest Trail (PCT). She found herself unable to turn away fromthe three separate cases despite challenges in the inquiry into them.

Trail of the Lost was her answer.

It's an absorbing nonfiction narrative(叙事) about the three hikers, including their lives and those ofthe people looking for them. It also explores the history of the PCT and the rich subculture, practices andeven literature that surround it and those who undertake the 2,650-mile journey.

The book is a rich multilayered narrative that works on three different levels. The first is the story ofeach of the three hikers. Lankford offers a biography(传记) of each of the missing men and shows themthrough the eyes of those who knew them well and those who joined the search.

Right underneath the narratives about the three hikers are the stories of everyone looking for them.Lankford played a role in each search but she allowed friends, family and even strangers to occupy centerstage throughout most of the narrative. The story looks at the role of missing person Facebook groups inthe searches and how crucial word of mouth can be. Many warm-hearted individuals came forth andbecame instrumental in the searches or provided valuable information. But Lankford also writes of themany who lied for no apparent reason and confused the investigations.

The narrative also shines a light on diverse aspects of the PCT. Lankford, who has hiked the entireAppalachian Trail and was the first person to mountain bike the 800-mile Arizona Trail, knows just howthe PCT is physically and mentally demanding. Besides, the book explores threats from mountain lions topeople with bad intentions who don't observe the PCT's unspoken moral rules, serving as a revelation of the well-known, hidden or ignored dangers of the PCT.

Written with a clear, fast-paced, straightforward style, Trail of the Lost is as full of hope andhumanity as it is packed with pain, sorrow, danger and tension. Read it and you'll find more than youseek.

Marath on is one of the most difficult races in track and field, at a little over 42 kilometers. To be aworld-class marathoner, you must run that distance in two and a half hours. But for some, completing amarathon race is a lifelong dream.

Jacqueline's dream of being a world-class run ner began when she was a child in Kenya. She soonrealized she had the talent and the willpower to compete. She also knew she would have to train full-time,which meant not being able to work to help support her family. But she was confident that she could bringhome prize money.

Jacqueline traveled to China to compete in the Zheng-Kai marathon knowing she had a good shot atwinning the race, but more importantly, the $10,000 prize that went with it. She was leading the women'sdivision when a male runner arrived at the water station. The man had trouble drinking water because abirth defect(缺陷) had left hı m without hands, and he struggled to drink from a plastic bottle. But anyassistance from fans or race officials would result in his disqualification. Jacqueline noticed the man andimmediately knew that he needed help. She grabbed a water bottle and helped him get the water his bodyneeded to complete the race.

Runner after runner passed Jacqueline. Her hopes of winning were getting lost in numerous runnersahead of her. With only 4 kilometers left in the race, and certain that the male runner would now finish,Jacqueline picked up her pace and finally finished second.

That day, Jacqueline missed out on first place, but she finished something more important: humanity.She return ed home with the smaller prize of second place, but to her family, she brought home somethingmuch more valuable to home: the right example.

This is a great demo for learning more about how to draw people.

Stage 1 With a 4H pencil, sketch an egg-shape for the head, in three-quarters view. Sketch the neckand shoulders. Add a circle indicating the shoulder joint. Check your proportions with one of theproportioning tools.

Stage 2 Add lines for the upper and lower forearm. For correct proportions, compare the length of theupper and lower arm to the height of the head, using one of the proportioning tools. Sketch lines that toindicate the sides and bottom of the basket. Add lines that indicate the ridges of the hand's knuckles andthumb. At this stage, the hand should look like a mitten, since the individual fingers are not yet defined.

Stage 3 Sketch in placement lines for the eyes and nose, and add a line for the center of the face.Sketch ellipses for the basket. Then go back and refine the eyes, nose, mouth and eyebrows. Add theindividual fingers on the hand.

Stage 4 Sketch the ear and add more definition to the fa cial features, arm, hand and fingers. Eraseany obsolete guideline with a white vinyl eraser. Add the basic form of the clothing and head scarf, notingwhere major folds occur. Also add short lines indicating the arm on the far side of the basket.

Jimmy is an automotive mechanic (汽车修理师), but he lost his job a few months ago. He is warm-hearted and make people feel safe. He is very helpful. Especially when people ask him for help, he seldom refuses. But he is very shy. He doesn't have enough confidence to start up conversations with strangers. So he is always afraid to apply for new jobs.

One day, he gathered up all his strength and decided to attend a job interview (面试). His appointment was at 10 a.m. and it was already 8: 

30. While waiting for a bus to the office where he was supposed to be interviewed, he saw an elderly man wildly kicking the tire of his car (踢车轮). Obviously there was something wrong with the car. Without the slightest hesitation, Jimmy immediately went up to give him a hand. When Jimmy finished working on the car, the old man asked him how much he should pay for (支付) the service. Jimmy said there was no need to pay him; he just helped someone in need, and he had to rush for an interview. Then the old man said, "Well, I could take you to the office for your interview. It's the least I could do. Please. I insist." Jimmy agreed.

Jimmy got in the old man's car, feeling uncomfortable and embarrassed, not knowing what to say. The old man broke the silence and after some small talk, he learned that Jimmy was nervous about his interview. Therefore, he said, "Don't worry, young man. Your good heart will bring you many great things, including a job."

Upon arrival, Jimmy found a long line (长队伍) of applicants waiting to be interviewed. Jimmy still had some grease (油垢) on him after the car repair, but he did not have much time to wash it off or have a change of shirt. One by one, the applicants left the interviewer's office with disappointed looks on their faces.

These years, Harbin has been making every effort to promote (it) ice and snow tourism. It has planned (develop) a series of ice-and-snow products, (include) key routes and must-see places. The 2025 China Ice Snow Festival will run through the whole January, and it will (great) attract lots of visitors from both home  abroad.

So, why not just go and have look? For people from South China, the gorgeous winter scenery is amazing. For those are from abroad, they will feel the unique passion (热情) about the ice and snow in Northeast China. What's more, visitors can also enjoy various(activity); for example, there are many parties that(hold) annually for the local people. In a word, you'll love Harbin winter!

How to choose a right major is a must for students who will go to university. But there are some problems. . Others pick a major and later realize that is not for them and then change their mind. If you are one of those students, do not worry. Here are some suggestions for you.

What are your interests?

Make a list of the things you enjoy outside and inside the classroom. . Try to choose a major that will keep you the happiest in the long run. 

Get advice

Another way to narrow down your choices is to explore the major in greater detail by asking people who are currently in the position you may apply for. You can ask them: How did you get to where you are today? What licenses would be most helpful? ? 

Another source of advice is your school adviser. They regularly help individuals assess(评估)which classes to take and how many credits are involved in each course. 

It's OK to not know

. There are some colleges that give you the opportunity to take a variety of classes before making a decision.

A. Discuss with your parents

B. Do you enjoy what you do

C. Talk to your school adviser

D. What do you think of the life after graduating

E. Then think of majors that relate to your interests

F. It is fine to start college with an undecided major

G. Many students don't know what major is best for them

Think about what you like to wear on the weekend. There's a good chance that you like to put on a pair of blue jeans（牛仔裤）. At any moment, about half of the world's population is wearing jeans. But according to a new study, our love for jeans may be bad for earth. The cloth used to make jeans might be putting some sea animals in danger. Every time we wash our jeans, small bits ofit will flow out of our washing machines and into the world's rivers, lakes and sea.

You might wonder: isn't the cloth made of something natural? How can it become a danger to nature? Well, when making jeans, the cloth is treated with many types of man-made chemicals. Scientists aren't yet sure how the chemicals（化学品） in the cloth might harm animals.

In the study, the scientists also washed jeans to see how many bits of the cloth on average each pair would drop per wash. The answer was worrying: about 50,000. Not all of them make their way into the environment. Wastewater treatment plants hold back 83 to 99 percent of them. This may sound pretty good. However, one percent of 50,000 are still 500 per wash. Now think about the number of jeans around the world and the times each of them gets washed. As a result, a large amount of the cloth still gets into the environment. 

Does this mean we shouldn't wear jeans? Probably not. "We need to buy fewer clothes and only wash them when we truly need to do it," says Sam Athey, one of the scientists. "You don't need to wash your jeans after having worn them only a few times."
