o try out to do Now we see being a volunteer is great. Would you like to be a volunteer? What are you good at? What kind of volunteer job would you like to do? Please plan a volunteer schedule in each group. 以上两句中的 each和 every是一对近义词，但各自的侧重点不同。 1. Mario Green and Mary Brown from Riverside High School give up several hours each week to help others. He volunteers at an animal hospital every Saturday morning. 1) 从语义上看，两者都可表示 “每个”， “一切的”。 很多时候，两词可以互换使用，但意思略有差别： • each强调个性，着眼于整体中的个体。 例如 : Each man has his own name. 每个人都有自己的名字。 Each time you practice, you get better at playing tennis. 每一次你进行网球练习，你都会打的更好。 • every强调共性，着眼于整体。 例如 : I get sick every time I eat seafood. 每次我吃海鲜都会生病。 Every one of your must attend the meeting. 你们每个人都必须参加会议。 2) 从语法上看， each可用形容词和代词， 而 every只用作形容词： He gave two to each (person). Each (school) has its own library. We have every reason to believe that the operation will be a success. 我们完全有理由相信手术会取得成功。 every和 each用于主语时，谓语均要求单数匹配 : Each student was asked the same question. 每个学生都被问了同样的问题。 Every child was dressed in a costume. 所有的孩子都穿了演出服。 3) 两种不可使用 each的情况： 切勿将 each和 almost, nearly及 not搭配使用，应用 every: Almost every cake was sold. 几乎所有的蛋糕都卖完了。 Not every student went on holiday. 并非每个学生都去度假了。 切勿在否定结构中使用 each, 应用 none: None of the books are mine. 没有一本书是我的。 （不说： Each of thee books are not mine.） 2. …but I want to learn more about how to care for animals. 但是我想学习更多关于如何照顾动物的事。 how to。
