短语用法:
在使用时要注意人称和时态。
1.人称
①人称代词做主语:
主语是I时,be动词是am;类似地,you/we/they,用are; he/she/it/name,用is。比如:They are from China.(他们来自中国。)
②单/复数做主语:
主语是名词单数时,be动词用is;是复数时,be动词用are。比如,The cat is from my country.(这只猫来自我的国家。)
2.时态:
①一般现在时:(注意be动词的不同使用)
I am from...; you/we/they are from...; he/she/it is from。比如,We are from Class One.(我们是一班的。)
②一般过去时:(同样注意be动词的不同使用)
I/he/she/it was from...; you/we/they were from...
比如,He was from Hong Kong.(他之前来自香港。)
