When we see a person in trouble, our immediate idea is to give a hand. If not, we'll feel uncomfortable. But what if we see an animal in danger, will we do the same?
This question was raised after a group of penguins were saved from an icy gully*. It was filmed for the BBC wildlife series Dynasties. The film team was frightened when they' saw: that 'a group of penguins had fallen into a gully and been trapped*with the young. The team built a slope* so that a few of the penguins could save themselves.
The case has attracted the public attention: Audiences watching this film all felt relieved in the end. "My heart was beating really: quickly at first while watching those penguins in a gully." the audience Kathryn Shaw said, "But I finally took a deep breath when noticing that- slope! I understand not intervening directly, but a helping hand isn't troubling, right?"
However, others think that human intervention. It's an natural. It's an unwritten rule that film makers are there only to watch; not to have a hand in it, according to CBS News. You can't have sunshine throughout your life. To have done anything else would only make things worse." "said a famous show's creator David Attenborough.
In this case, however; Mike Gunton, the producer of Dynasties; said that this was only an accidental situation "There were no animals going to suffer by intervening" It wasn't dangerous. You weren't touching the animals and by doing this they had the chance to run away from in the gully." he told the BBC. Such cases are not new to the wildlife photographed ·Paul NickIen, who told Metro." If it's ever a, predator*situation, no matter how heart-breaking, you stay out of the way. Even when you are watching an adult polar bear eat a baby sea dog." But he said that he would help animals if he saw no influence to nature.
Actually, there will always be two sides to the coin; and human beings will forever argue about this situation.
No, I'm.

"I spent my whole life doing one thing," Gu Fangzhou once said. Known as "the father of sugar pills (糖丸)", Gu passed away on January 2, 2019. Eight months later, he received a national honorary-title (荣誉称号) "the People's Scientist" for his polio (脊髓灰质炎) research.
Gu Fangzhou, a famous medical scientist, was born in June, 1926. Gu's family faced a difficult time with the sudden death of his father. He studied hard and finally entered Peking University as a medical student in 1944. After graduation, Gu made the decision to work to help improve public health.
In 1955, polio broke out in Nantong, Jiangsu Province. It paralyzed (使瘫痪) 1,680 people, mostly children aged below seven. It spread to neighboring areas and resulted in 466 deaths. Gu was asked to lead polio research in 1957. "At that time the only way to prevent polio was to invent a vaccine (疫苗)," said Gu.
In 1959 Gu succeeded in developing the first polio live vaccine. Later, he developed the "sugar-coated pill" vaccine in the early 1960s. It not only tasted better but was more affordable and easier to keep. To test the vaccine, Gu tried the vaccine in person and later his one-month-old son was vaccinated. This inspired his team to vaccinate their kids. They became the first group of people in China to try a polio vaccine. "If we don' t believe in what we produce, how can others believe in it?" said Gu.
Gradually, the sugar-coated polio vaccine was made available in China. It saved millions of people, especially kids, from being disabled. In 2000, the World Health Organization (WHO) announced that China was already a polio-free country. "We feel satisfied. I can tell people that I tried my best, and your kids will no longer get polio," said Gu. "That's all we hoped for. "

Why are dogs our best friends? Maybe because they can understand our words much better than we thought, according to a study in Hungary. The study showed that dogs understand not only what we say, but also how we say it. "The results were exciting and surprising," said Attila Andics, a researcher from a university in Budapest.
For the study, the researchers first trained 13 dogs for months. The dogs had to sit quietly inside machines so that the researchers could check their brain activities. Then the researchers put headphones(耳机) on dogs and played people's voices to them. There were four different voices. Some were of positive words, such as "well done", or negative words like "not good". The words were also in different tones(语气). Some were positive, some were neutral(中立的), and some were negative.
Brain scans(扫描) showed that dogs could recognize(辨别出) different words, as well as the tones of words, much like people do. The positive words with a positive tone brought the strongest activity in their brains' reaction centers(反应中枢). "It showed that for dogs, nice words can work very well as a reward(奖赏), but it works best if both words and tones match," said Andics.
They also found that dogs deal with meaningful words with the left side of the brain and tones with the right. Human brains work in the same way.
Andics said it gave us a new understanding of language. That is to say, not only humans understand the meaning in words, but also the dogs.
Dear Grace,
Thanks for your letter. I'm writing to tell you something about our next term.
Do you love volleyball? On September 7th, we have a volleyball game at four in the afternoon. It's interesting for me. My teacher says we can see some great volleyball stars in the volleyball game. In October, we have a school trip. It's relaxing for us. In November, we have an art festival and an English party. The art festival is on November 3rd. The English party is on November 18th. It's in our classroom. Sally's birthday is on December 11th. I want to buy a white model plane for her. Tim wants to buy a book. You can buy a birthday cake for her. She must be very happy.
It's really a fun term, isn't it?
