你好，我是一个完全的初学者，到目前为止，我已经能够借助这个平台和其他一些论坛解决所有问题。
但对于这个，我找不到合适的线索。
我将一些文本从 word 粘贴到 texmaker 中 latex 文档的子部分。此文本块的最后几个单词在代码窗口中显示为灰色，当我按下快速构建时，pdf 中缺少这些单词。即使我尝试输入这最后几个单词，它们仍然显示为灰色，在 pdf 中不可见。没有发生错误。

\section{Glioblastoma multiforme}
\subsection{Epidemiology}
Glioblastoma multiforme (GBM) is the most common malignant primary brain tumor in adults.
It is also one of the most common primary brain tumors overall, ranking second after meningiomas.
In the United States 3.19 individuals per 100,000 were diagnosed with GBM each year, between 2005 and 2009.
An extrapolation reveals approximately 9,000 new cases per year (Dolecek et al. 2012).
An earlier study conducted in Switzerland revealed a similar incidence of 3.32 and 2.24 per 100,000 individuals per year between 1980 and 1994, for male and female patients respectively (Ohgaki et al. 2004).
Although any age group can develop this kind of tumor, the average American is 64 years old when diagnosed with GBM.
The male to female incidence rate ratio is 1.58. Glioblastoma is also the most aggressive primary brain tumor that holds the worst prognosis of all malignancies of the central nervous system.(Dolecek et al 2012).
There is no detailed data available on the epidemiology of malignant gliomas in Germany (Robert Koch Institiute 2012).
Despite great efforts in neurooncological research and a multimodal treatment approach, patients suffering from glioblastoma have a median survival of 14.6 months (Stupp et al. 2005).
However, a subgroup of long-term survivors that are believed to constitute 3-5% of all glioblastomas, exceed an overall survival of 36 months (Krex et al. 2007).
