在Studio 3T中，我已经创建了一个集合，我要在其中添加一个文档，然后弹出窗口显示标题为>>Insert JSON Document<<要将数据添加到文档中，然后我编写了这些项。

{
    "_id" : "5c18e1892998bdb3b3d355bf",
    "title" : "REST",
    "content" : "REST is short for REpresentational State Transfer. IIt's an architectural style for designing APIs."
}

{
    "_id" : ObjectId("5c139771d79ac8eac11e754a"),
    "title" : "API",
    "content" : "API stands for Application Programming Interface. It is a set of subroutine definitions, communication protocols, and tools for building software. In general terms, it is a set of clearly defined methods of communication among various components. A good API makes it easier to develop a computer program by providing all the building blocks, which are then put together by the programmer."
}

{
    "_id" : ObjectId("5c1398aad79ac8eac11e7561"),
    "title" : "Bootstrap",
    "content" : "This is a framework developed by Twitter that contains pre-made front-end templates for web design"
}

{
    "_id" : ObjectId("5c1398ecd79ac8eac11e7567"),
    "title" : "DOM",
    "content" : "The Document Object Model is like an API for interacting with our HTML"
}

{
    "_id" : "5c18f35cde40ab6cc551cd60",
    "title" : "Jack Bauer",
    "content" : "Jack Bauer once stepped into quicksand. The quicksand couldn't escape and nearly drowned.",
    "__v" : 0
}

之后，当我单击Add Document按钮时，出现另一个标题为>>JSON Validation<<的弹出窗口，在该窗口下面显示“在第8行检测到孤立字符，第1列”。而且我不能一次插入这些文档。

如何在文档中一次插入所有这些对象？
