    Louis Pasteur was born in Dole, France on December 27, 1822. His family was poor, and during his early education Pasteur was an ordinary student who enjoyed art and singing. However, when Pasteur was exposed to science as a teenager, he knew he had found his career.

    In 1838, Pasteur went to college to become a science teacher. He then became a chemistry professor at the University of Strasbourg. He got married in 1849 and had five children. However, three died young from typhoid fever (伤寒症). It was the deaths of his children that drove Pasteur to investigate the infectious disease in order to find a cure.

    During Pasteur's time, people believed that bacteria (细菌) appeared due to “spontaneous generation (自然发生)”. They thought that the bacteria just appeared out of nowhere. Pasteur earned out experiments to see if this was true. Through his experiments he proved that germs (细菌) were living things that came from other living things. They didn't just spontaneously appear. This was a major discovery in the study of biology and earned Pasteur the title of Father of Germ Theory.

    As Pasteur learned more about bacteria, he began to think they may be the cause of diseases in humans. When the French silk market was threatened by a disease to silkworms (蚕), Pasteur decided to investigate. He discovered that this disease was caused by germs. By killing them from the silkworm farms, he was able to cease the disease and save the French silk business.

    Today Louis Pasteur is known as one of the most important scientists in history. His discoveries led to an understanding of bacteria and diseases that has helped save millions of lives.

    On a cold morning in 2015, five-year-old Lucas stood on the bank of Blue Star River, hugging a dead salmon（鲑鱼）against his thick yellow coat. He looked up at his father, Steve, who nodded encouragingly. "Go ahead," he said. "Put it in." The young boy dragged his feet forward and held the fish as far as he could into the shallow water. "It's floating!" Lucas yelled, delighted. For a moment, it's almost as if the handsome salmon could come back to life.

    Lucas' salmon was just one of 100 or so dead bodies that will land in Blue Star River in a half-hour activity this morning, delivered by dozens of volunteers. None of the salmon will rise from the dead, but Andy, president of the Fish Rescue Society, who has promoted this gathering, is carrying out the resurrection （复活）project of salmon.

    Andy led the group's campaign to recover this urban waterway's salmon population. "The Fish Rescue Society started exploring the possibility of recovering the salmon in the river in the mid-1990s, and they also focused on river recovery in cities worldwide."

    Andy and his group are devoted to giving the river a full make-over. This monumental repair job, supported by approximately $95,000 of funding from the Pacific Salmon Foundation over the past 15 years, has involved recovering the river-habitat of salmon and preventing it from wearing away. Work on the river's final section was completed in October 2016.

    When Joanne Morton and Lydia Shaw came across the Boston Public Market, which features only New England businesspersons, they knew they had to stop in. The women, visiting from southeastern Connecticut, always try to buy local. "We always try to support our local farmers and businessmen," says Ms. Shaw. "We're not into big companies," adds Ms. Morton.

    They aren't alone. A great number of Americans continue to be attracted by "local" food and to buy it, according to recent surveys from the International Food Information Council Foundation, the Pew Research Center, and British polling firm Ipsos. But what does it mean to shop local? For some, local is still a matter of geography. For others, it is about supporting their local economy (经济). And for still others, it is about knowing where their food comes from and how it is made, even if it is coffee shipped from a Costa Rican company. In 2008, Congress passed a bill that gave money to support local food. According to the Food, Conservation, and Energy Act, a product that can be considered local has to travel less than 400 miles.

    But Lydia Zepeda, a professor at the University of Wisconsin-Madison, has found the largest agreement about what is local is any product that comes from within an hour's drive. "But is that with or without traffic?" She asks. "What if it crosses state lines?" adds John Hayes, a food science professor at Pennsylvania State University. "A customer might like to buy local to help an old town," he says. "Or maybe it's just because local food tastes better." It is for Kaitlin Bohon. "I taste a difference," she says at the Boston Public Market. For Ms. Bohon, buying local is both about supporting New England business and knowing who grew and handled her food.

    Have you ever been into a cave? If not, please follow us and explore some of the most beautiful caves from around the world!

    Marble Caves

    Located in the center of Lake General Carrera, the Marble Caves in Chico, Chile, are only accessible by boat. The surrounding crystal clear waters allow visitors to see the rock formations beneath them while the rock ceilings above change color (depending on the writer levels and the season). The best time to visit: during sunrise and sunset, when the sun's rays light up the cave walls, making it an experience to remember.

    Reed Flute Cave

    Reed F1ute Cave known as "the Palace of Natural Arts" is located in the northwest of Guilin in southern China. The limestone cave offers a grand fairyland of stalactites (钟乳石), stone pillars, stone curtains, birds, plants and animals in fantastic shapes and colors.

    Fingal's Cave

    This incredible sea cave is located on the uninhabited island of Staffa in Scotland. The cave's size, shape, and naturally—arched (拱形的) roof combine with the waves to create strange sounds that enhance its cathedral—like atmosphere.

    The Blue Grotto

    The Blue Grotto is the symbol of Capri. It is a sea cave found on the coast of the island and is a well-known spot to all who visit the area. This cave is unique for its brilliant blue light which comes from two sources: the entrance to the cave and a bigger hole beneath the entrance. When viewed from inside the cave, the entrance appears as a brilliant white light just above the waterline, while the underwater hole, which is the larger source of light, provides a blue light.

Forget Cyclists, Pedestrians are Real Danger

    We are having a debate about this topic. Here are some letters from our readers.

    Yes, many cyclists behave dangerously. Many drivers are disrespectful of cyclists. But pedestrians are probably the worse offenders.

    People of all ages happily walk along the pavement with eyes and hands glued to the mobile phone, quite unaware of what is going on around them. They may even do the same thing while crossing a road at a pedestrian crossing or elsewhere. The rest of us have to evade (避让) them or just stand still to wait for the unavoidable collision.

    The real problem is that some pedestrians seem to be, at least for the moment, in worlds of their own that are, to them, much more important than the welfare of others.

——Michael Horan

    I loved the letter from Bob Brooks about cyclists (Viewpoints, May 29). I am afraid they seem to think they own the roads.

    I was walking across Altrincharn Road one morning when a cyclist went round me and on being asked what he was doing he shouted at me.

    The government built a cycle lane on the road but it is hardly used.

    The police do nothing. What a laugh they are!

    The cyclists should all have to be made to use the cycle lanes and wear helmets, fluorescent (发荧光的)jacket and tights at night and in the morning. They should pay some sort of tax and be fined for not wearing them.

——Carol Harvey

    Cyclists jump on and off pavements (which are meant for pedestrians), ride at speed along the pavements, and think they have a special right to go through traffic lights when they are on red.

    I was almost knocked down recently by a cyclist riding on the pavement when there was a cycle lane right next to him.

    Other road users, including horse riders, manage to obey the rules so why not cyclists?

    It's about time they had to be registered and insured, so when they do hit a pedestrian or a vehicle, or cause an accident, at least they can be traced and there might be an opportunity to claim.
