"There are five stages of development,each is linked to a particular place.和There are five stages of development,each is linked to a particular place.兩個(gè)句子...“---你這兩個(gè)句子一模一樣.·····...嗯啊 謝謝您的答復(fù)我懂了然后在此基礎(chǔ)上想再問您一個(gè)問題：There are five stages of development and each is linked to a particular place.和There are five stages of development ，and each is linked to a particular place.這兩個(gè)句子都正確嗎？加個(gè)逗號(hào)有什么區(qū)別沒有。謝謝期待您的回復(fù)There are five stages of development and each is linked to a particular place.There are five stages of development，and each is linked to a particular place.無區(qū)別。就這兩句話而言，第一句較多用。
