Octopi（plural of octopus）are eight-legged animals that live almost exclusively in the sea, feeding on small h, crabs, and other marine prey. Their physiology and behavior are fairly well understood. A recent report, however, surprised scientific experts:dozens of octopi were seen crawling on a sandy beach in great This behavior was very unexpected because octopi cannot survive on land for more than several minutes. Indeed, most of the octopi found crawling on the beach quickly died. Three possible explanations have been proposed for the unusual behavior of these octopi
Search for food
Some scientists view the search for food as a likely explanation. Recently, octopi populations have been facing shortages in available food. As a result, octopi have increased their hunting activity in shallow waters, near the shoreline, where they search for prey such as crabs. It is possible that a group of octopi were hunting too close to the shoreline, and when the sea receded withdrew）， the octopi were left stranded on land
Female die-of
Mature female octopi lay eggs and guard them until they hatch. Once the eggs hatch, female octopi feed less, become worn out and disoriented, and eventually, die off. It is possible that a group of female octopi nearing the end of life might have become disoriented and confused and so crawled out of the sea
Recent storms
A final explanation is that major storms that took place in the area forced the octopi to escape from the sea onto the beach. Storms create strong underwater currents that can injure animals. Also, low atmospheric pressure associated with storms may cause changes in the behavior of some sea animals. Perhaps the octopi wanted to escape the local waters because of the injuries caused by the stormy seas or because of the low atmospheric pressure. Unfortunately, they ended up on the beach

Professor：
Today, I’d like to discuss choices people make in terms of where they decide to live. Some people choose to spend their entire lives in one town or city. Others leave their hometowns and might even move several times from one town or city to another. I’d like to get your thoughts on this subject. Do you think it is better to live in one town or city all your life? Why or why not?
Living in one place your whole life is the better option. It allows you to form strong bonds with neighbors and members of your community. You know that if you stay in one place for a long time, you will always have friends you can rely on when you need help.
Moving from one city to another has some advantages. Adapting to different situations is an important skill to have in life, and moving forces a person to develop this skill. Having to make new friends and start over in a new city is a challenging exercise that builds character.
