我们来逐步分析这个题目：

题目内容：

> The word "cram" in the second paragraph is closest in meaning to ____.

这是一个考察词义理解的题目，要求我们根据上下文判断“cram”这个词在文中最接近的意思。

选项分析：

我们先逐个理解选项的意思：

A. put something into a container, especially in a hurry
意思是“把某物放进容器里，尤其是匆忙地放”。这描述的是物理上的“塞东西”的动作，但可能不是最贴切的词义。

B. put many things into a place at one time that makes it completely full
意思是“一次把很多东西放进一个地方，直到它完全满”。这更强调“塞满”的状态，但不一定是匆忙或临时的。

C. teach students as much as possible in a short time before the examination
意思是“在考试前短时间内尽可能多地教学生”。这个选项描述的是“临时抱佛脚”的教学方式，虽然和“cram”有关，但更偏向“教”的行为，而不是“学”的行为。

D. put too much knowledge into the brain, although there is hardly enough room for it
意思是“把太多知识塞进大脑，尽管大脑几乎没有空间容纳它”。这个选项描述的是“临时突击学习”，即“临时拼命记忆大量知识”，非常贴合“cram”的常见用法。

“cram”的常见含义：

在英语中，“cram”最常用于学习场景，表示“临时突击学习”，尤其是在考试前短时间内拼命记忆大量知识。比如：

• I crammed for the exam all night.
  （我通宵临时抱佛脚准备考试。）

这种行为的特点是“短时间内塞入大量信息”，即使大脑可能已经“超载”了。

正确答案：

结合“cram”的常见用法和选项内容，最贴近的含义是：

> D. put too much knowledge into the brain, although there is hardly enough room for it

最终答案：

$\boxed{D}$
