Today we are going to talk about a favorite physical activity . Whether outdoors or indoors , swimming is a fun way to stay in shape . And one of the great things about swimming is diving . For a very short time , a diver flies through the air like a bird . Then they land in the cool water below , usually with their hands and head leading the way . But jumping into a body of water headfirst is just one meaning of the word "dive ." "To dive into something " can also mean to start working on a project with lots of energy but not , perhaps , a lot of planning . Let's say two friends are really excited to dive into a new business together . So , it was not a big surprise when the company went under a few months later . Friends told them that they had a good idea , but they simply dove in too quickly . If you dive into something headfirst , you are even more excited and even less prepared ! For example , a man I know really wanted to learn basic home repair . He was very excited to begin on a home project . So , he dove in headfirst , knocking down walls and tearing out the floors . Unfortunately , he didn't know enough to rebuild his house . He ended up hiring a construction team for that . "To dive into something " can also mean you are simply really excited to do it . Planning is not an issue or problem . And sometimes we add the word “right .” This makes it sound more conversational . For example , the children must have been very hungry after swimming all day . They dove right into the pizza the minute it was served ! But now , let's go back to the diving that relates to swimming . Sometimes divers dive off a mountain cliff . They are called cliff divers . Some dive off the side of a pool . Others dive off a diving board . Diving boards are springy . They are made of a material that can bend . Diving boards are a kind of springboard . They are a board that springs you into the air ! In addition to diving , a springboard is useful in other situations . A springboard can be something that helps you start an activity or process . We can also call this a jumping off point , just as when you jump off a diving board . For example , when preparing for this program , I often take note of the expressions my friends use . So , for me , these conversations are often springboards to new stories for this show . The term "springboard " can also mean a point of departure . Let's hear two co-workers use it this way . Boy , Emanuel did not stay long at his job here , did he ? But I'm not surprised . I knew he'd move quickly from this job to the next . How did you know that ? On his first day , he told me that this job was only a springboard to a better position . Well , at least he was honest . So , besides cliff diving and diving off a diving board , there is another kind of diving -- scuba diving . Scuba diving is an underwater activity . You swim underwater while wearing special equipment , including a tank , or container , filled with compressed air . Scuba is an acronym . It is short for self-contained underwater breathing apparatus . With tanks of air on their backs , scuba divers are able to dive deep into the sea . On a deep sea dive , you might see some very strange sea creatures ! On land , a deep dive is when you explore an issue in great detail . Oftentimes , the media coverage of some issues is too shallow , meaning it doesn't explain enough . But sometimes a news agency is able to do a deep dive on issues that people really care about . Hopefully , this program will make you want to dive right into your English studies ! What would like to dive into ?
