用来分隔并列的单词或短语。The school has a vegetable garden in which the children grow cabbages,onions, potatoes,and carrots.学校有一个菜园,孩子们在里面种卷心菜、洋葱、土豆和胡萝卜。
当直接引语位于说话者的前面时,引语的句末往往用逗号隔开,且位于引号内。如:I don't agree,I replied.如果直接引语位于说话者的后面时,逗号用于说话者的动作之后,且位于引号外。如:Steve replied, No problem。
用来分隔主句和从句。After we had had lunch, we went back to work.我们吃过午饭后,就回去工作了。逗号常用来分隔句子中的非主要成分,如插入语、同位语等。如:Gunpowder is not, of course,a chemical compound.火药当然不是一种化合物。
逗号常用来分隔句与句之间的连接词,比如however、therefore等。She felt ill.She went to work,however,and tried to concentrate.她觉得不舒服。但她还是去上班,努力集中精神。
