一首歌教你学会主谓一致的搭配，一起来唱吧。This is, this is, this is a bag. That is, that is, that is a pen. It is, it is, it is a cup. He is, he is, he is a man. She is, she is, she is a girl. Surely is, surely is, surely is a teacher. We are, we are, we are friends. These are, you are, you are students. They are, they are, they are boys. These are, these are, these are apples, those are, those are, those are pears. 你都学会了吗？学会了给老师一颗小星星吧。
在英语学习中，主谓一致是个关键。像This is a bag、That is a pen等简单句，能帮你快速掌握。首先要明确主语单复数，单数主语用is，复数主语用are。比如He is a man，She is a girl，这里he和she是单数第三人称，所以用is；而We are friends，They are boys，we和they是复数，就用are。还有These are apples，Those are pears，these和those指代复数，也要用are。多做练习，比如用This is/That is/It is等句型描述身边事物，加深理解。遇到复杂句子，先找出主语核心词判断单复数。掌握好主谓一致，英语表达会更准确自然，为后续学习打下坚实基础。
