Each is used in front of a singular noun and is followed by a singular verb. * each 用于单数名词前，后接单数动词：◆Each student has been given his or her own email address.每个学生都得到一个自己的电子邮件地址。 The use of his or her sometimes sounds slightly formal and it is becoming more common to use the plural pronoun their.有时候 his 或 her 听起来有点正式，故日渐普遍使用复数代词 their：◆Each student has been given their own email address.每个学生都得到一个自己的电子邮件地址。
When each is used after a plural subject, it has a plural verb. * each 用于复数主语后，谓语动词用复数：◆They each have their own email address.他们每个人都有自己的电子邮件地址。
Every is always followed by a singular verb. * every 后总是接单数动词：◆Every student in the class is capable of passing the exam.班上每个同学都有能力通过这次考试。
Each of, each one of and every one of are followed by a plural noun or pronoun, but the verb is usually singular. * each of、each one of 与 every one of 后接复数名词或代词，但谓语动词通常用单数：◆Each (one) of the houses was slightly different.每座房子都稍有不同。◆I bought a dozen eggs and every one of them was bad.我买了一打鸡蛋，个个都是坏的。 A plural verb is more informal.用复数动词则较非正式。
