1. 主词+be动词例句:I am a student.这个句子中,be动词am作为谓语动词,连接主词I和表语student,表示主词的身份或状态。
在这个句子中,be动词am表达的是现在时态,而且主词是第一人称单数形式,所以用am而不是is或are。
2. 主词+be动词+形容词例句:He is tall.这个句子中,be动词is作为谓语动词,连接主词he和形容词tall,表示主词的特征或状态。
同样地,be动词is表达的是现在时态,而且主词是第三人称单数形式,所以用is而不是am或are。
3. 主词+be动词+名词例句:She is a doctor.这个句子中,be动词is作为谓语动词,连接主词she和名词doctor,表示主词的身份或职业。
同样地,be动词is表达的是现在时态,而且主词是第三人称单数形式,所以用is而不是am或are。
4. 主词+be动词+介词短语例句:They are in the classroom.这个句子中,be动词are作为谓语动词,连接主词they和介词短语in the classroom,表示主词的位置或状态。
同样地,be动词are表达的是现在时态,而且主词是第三人称复数形式,所以用are而不是am或is。
5. 主词+be动词+副词例句:We are here.这个句子中,be动词are作为谓语动词,连接主词we和副词here,表示主词的位置或状态。
同样地,be动词are表达的是现在时态,而且主词是第一人称复数形式,所以用are而不是am或is。
