<p>在 is used to indicate the location or time that something happens. The operative word is "indicate"; it's used to provide explanations.</p>

<p>You can omit it when it serves the role of a preposition (e.g., with the meanings "in", "from", or "to"). However, you need to keep it when it's acting as the main verb (e.g., in "Where <strong>is</strong> the cat?" or "那隻貓<strong>在</strong>哪裡？").</p>

<p>In Chinese sentence, I know Place and Time complement needs to follow these orders: </p>

<p>(1) Subject + Time + Place + How + Do sth</p>

<p>(2) Time + Subject + Place + How + Do sth</p>

<p>I notice that Time Complement can omit 在, for example：</p>

<p>（在）下课之后，玛丽去足球场。</p>

<p>Besides, Place Complement always starts with 在：</p>

<p>在包里，他拿了一本书。</p>

<p>So, <strong>how can I know when to use and omit 在 in Place complement, Time Complement?</strong></p>

I would say 下课后，玛丽去了足球场 / 下课后玛丽要去足球场. But never  下课后，玛丽去足球场. I would say 他**从**包里拿了一本书出来 but not 在包里，他拿了一本书 / 他在包里拿了一本书. 在包里 is used to describe 他 in this sentence which should be incorrect.
