Question

Let's go play in the park.为什么go后面没有to呢
（出自PEP小学英语五年级下册-Unit 1-Let's sing-Weekend）

Answer 1

你说的这句话是一首歌的歌词.
Weekend
Let’s go out on the weekend.Let’s go play in the park.Let’s play football or basketball.I have fun.It is fun for all.
Let’s go out on the weekend.Let’s go play in the park.Let’s go shopping or play in the sun.The weekend is fun.It’s fun for all.
歌词一般不太严格的合乎语法,再说了,小学阶段,孩子们只要会读,会唱就可以了,不要太强调语法结构.
其实这句话可以理解为Let's go and play in the park.省略了and而已
