獨立子句是包含主詞和動詞的短句，且已經表達了完整的思維，所以獨立子句可以獨立存在，不用再加其他的東西。
Jess finalized the plan for the trip. Jess敲定了這次旅行的計劃。Mary cleaned the room before making breakfast. Mary在做早餐前打掃了房間。Joseph was impressed with the proposal. Joseph對這個提議印象深刻。可以以以下3種方式連接2個獨立子句
1.) 以使用分號連接兩個獨立的子句。
Jess finalized the plan for the trip; he sent the itinerary via e-mail. Jess敲定了這次旅行的計劃；他用電子郵件發送了行程。Mary cleaned the room before making breakfast; Martha rushes for breakfast without cleaning up. Mary在做早餐前打掃了房間；Martha沒有打掃就衝過去吃早餐。Joseph was impressed with the proposal; he accepted it with no questions. Joseph對這個提議印象深刻；他毫無疑問地接受了這個提議。2.) 以對等連接詞連接獨立子句。
用首字母縮寫詞 FANBOYS（for、and、nor、but、or、yet、so）很容易記住對等連接詞，別忘記要在對等連接詞之前加上逗號。這是為了避免連續句子。
Jess finalized the plan for the trip, and he sent the itinerary via e-mail.Jess 確定了旅行計劃，並用電子郵件發送了行程。Mary cleaned the room before making breakfast, but Martha rushes for breakfast without cleaning up. Mary在做早餐前打掃了房間，但Martha沒有打掃就衝去吃早餐。Joseph was impressed with the proposal, so he accepted it with no questions. Joseph對這個提議印象深刻，所以他毫無疑問地接受了這個提議。3.) 使用連詞副詞來組合兩個獨立子句。
常用的連接副詞有moreover, however, consequently, finally…等。在使用連接副詞時，要記得在第一個獨立子句之後使用分號，然後是連接副詞，再來是逗號，最後是第二個獨立子句。
Jess finalized the plan for the trip; moreover, he sent the itinerary via e-mail. Jess敲定了這次旅行的計劃；此外，他還用電子郵件發送了行程。Mary cleaned the room before making breakfast; however, Martha rushes for breakfast without cleaning up. Mary在做早餐前打掃了房間；然而，Martha沒有打掃衛生就衝去吃早餐了。Joseph was impressed with the proposal; consequently, he accepted it with no questions. Joseph對這個提議印象深刻，因此他毫無疑問地接受了這個提議。
