A worm has a segmented body: you can see the rings, but it is one animal. People also call an orange segmented because it pulls apart into pieces that belonged together. A show or a lesson can be segmented if it comes in chunks, one after another.

A worm蚯蚓 has a segmented body有一個segmented的身體: you can see the rings你可以看到一節一節的環, but it is one animal但牠是同一隻動物。People also call an orange segmented人們也會說柳橙是segmented, because it pulls apart into pieces that belonged together因為它可以剝成好幾瓣、而這些瓣原本就屬於同一顆。A show or a lesson一個節目或一堂課 can be segmented也可以說是segmented if it comes in chunks, one after another如果它是一段一段接連下去的

The word這個字 is a little more formal than比較正式一點，勝過 "in pieces,"「in pieces」（碎片） and it keeps the idea而且它保留了…的意思 that the bits belong to the same thing這些小塊本來屬於同一個東西, not a pile of leftovers而不是一堆零散的剩餘物

Though actually, science uses it in a tighter way for animals whose bodies are built in repeating units, while everyday talk uses it more loosely for anything clearly cut into sections. The picture is “parts, but still one thing.”

Though actually不過其實, science uses it in a tighter way科學上會比較嚴謹地用這個字 for animals whose bodies are built in repeating units指身體由重複單位組成的動物, while everyday talk uses it more loosely而日常說法用得比較鬆 for anything clearly cut into sections指任何明顯被切成好幾段的東西。The picture is它的畫面就是 "parts, but still one thing."「有好幾個部分，但仍然是同一個東西」
