我正在尝试重现此图表：
我在文档中读到tikz-qtree，我需要将根的大小计算为级别距离的倍数，但我可以让它工作。到目前为止，我已经：
\documentclass[ twoside,openright,titlepage,numbers=noenddot,headinclude,%1headlines,% letterpaper a4paper
footinclude=true,cleardoublepage=empty,abstractoff, % <--- obsolete, remove (todo)

\usetikzlibrary{arrows,decorations.markings,babel}
\begin{document}
\begin{tikzpicture}[every node/.style={align=left}]
\tikzset{

但结果是这样的（不适合页面）：
我做错了什么？
到目前为止我尝试过以下建议：
答案1
我可以建议用 Forest 作为树和sidewaysfigure位置吗？
首先，树：
\documentclass[tikz,border=10pt]{standalone}
\usepackage[edges,linguistics]{forest}
\begin{document}
\begin{forest}
forked edges,
where n children=0{tier=terminus}{},
[S
[NP
[Rolls-Royce\\NNP]
[Motor\\NNP]
[Cars\\NNPS]
[Inc\\NNP]
]
[VP
[said\\VBD]
[SBAR
[-NONE-]
[S
[NP
[it\\PRP]
]
[VP
[expects\\VBZ]
[S
[NP
[its\\PRP\$]
[U.S\\NNP]
[sales\\NNS]
]
[VP
[to\\TO]
[VP
[remain\\VB]
[ADJP
[steady\\JJ]
]
[PP
[at\\IN]
[NP
[QP
[about\\IN]
[1200\\CD]
]
[cars\\NNS]
]
]
]
]
]
]
]
]
]
]
\end{forest}
\end{document}
即使侧向放置，树也太宽了。与其缩放它（这应该是最后的选择），不如使用较小的字体大小，例如和\scriptsize通过更改来减少节点之间的空间s sep。进行这些更改后，树将适合并且比简单缩放的树更清晰。如果您使用视觉尺寸的字体，情况尤其如此。
\documentclass[twoside,openright,titlepage,numbers=noenddot,headinclude, footinclude=true,cleardoublepage=empty,abstractoff,BCOR=5mm,paper=a4,fontsize=11pt,ngerman,american]{scrreprt}

现在可以工作了！
\begin{figure}[h]
\resizebox{1.3\textwidth}{!}{%
\begin{tikzpicture}[every node/.style={align=center}]
\tikzset{
edge from parent/.style={
draw,edge from parent
path={(\tikzparentnode.south)-- +(0,-8pt)-| (\tikzchildnode)}
},
frontier/.style={distance from root=350pt} % Align leaf nodes
}
\Tree [.S
[.NP Rolls-Royce\\NNP Motor\\NNP Cars\\NNPS Inc\\NNP ]
[.VP said\\VBD
[.SBAR -NONE-
[.S
[.NP it\\PRP ]
[. VP expects\\VBZ

[.NP its\\PRP\$ U.S\\NNP sales\\NNS ]
[.VP to\\TO

cars\\NNS
]
]

]

]
\end{tikzpicture}
}
\end{figure}
问题是将叶子添加为节点，如下所示：
[.NP [.Rolls-Royce ] [.Motor ] [.Cars ] [.Inc ] ]
% The correct way
[.NP Rolls-Royce Motor Cars Inc ]
更新
按照建议疾病控制与预防中心我做了一些调整：
- 已移除
resizebox - 将字体大小减小至
tiny - 减少内部边缘之间的距离
代码及结果：
\begin{figure}[h]
\tiny
\begin{tikzpicture}[every node/.style={align=center}]
\tikzset{
edge from parent/.style={
draw,edge from parent
path={(\tikzparentnode.south)-- +(0,-8pt)-| (\tikzchildnode)}
},
frontier/.style={distance from root=208pt}, % Align leaf nodes
level 1+/.style={level distance=18pt} % Distance between levels
}
\Tree [.S

\end{figure}
更新 #2
我又做了一点小改动，让它看起来更像原版。叶子None应该在第 3 级，而不是与句子的其余部分对齐。为此，唯一需要做的更改是：
[.SBAR [.none ]
% instead of
[.SBAR NONE
结果：
