我们来逐题分析并完成这些句子，重点在于选择与斜体词（题目中未标出斜体，但根据语境可以判断）搭配得当的词语。这类题目考查的是词语搭配（collocation），即哪些词在英语中习惯性地一起使用，使表达更自然、地道。

1. Campus violence has been a(n) ______ (ongoing, steady) problem for decades in America.

• 分析：
  “problem”（问题）常与“ongoing”搭配，表示“持续存在的问题”，即“an ongoing problem”是一个常见搭配，强调问题从过去一直持续到现在。
  “steady”通常用于描述增长、进步、收入等，如“steady growth”（稳定增长），但不常与“problem”搭配使用。
  因此，“ongoing problem”更自然。

• 正确答案：ongoing

• 完整句子：Campus violence has been an ongoing problem for decades in America.

2. While providing an environment in which students can work with top experts in specialized areas, the project also aims to ______ (expose, show) them to other disciplines.

• 分析：
  这里动词需要与“them to other disciplines”搭配。
  “expose someone to something” 是固定搭配，意思是“使某人接触某事物”，常用于教育或经验领域。例如：“Students are exposed to different cultures.”
  “show”虽然意思接近，但“show them to other disciplines”语法和语义都不通。我们可以说“show them something”，但不能说“show them to disciplines”。

• 正确答案：expose

• 完整句子：...the project also aims to expose them to other disciplines.

3. With every ______ (ounce, bit) of strength I have, I am going to accomplish the project on time.

• 分析：
  “every ounce of strength” 是一个非常常见的英语表达，意思是“用尽全力”，其中“ounce”在这里是比喻用法，表示“一点点（力量）”。
  “bit”虽然也可以表示“一点点”，但“every bit of strength”虽然语法正确，但不如“every ounce of strength”地道和强烈。
  “with every ounce of strength” 更具表现力，常用于强调竭尽全力。

• 正确答案：ounce

• 完整句子：With every ounce of strength I have, I am going to accomplish the project on time.

4. Human behavior is especially difficult to study because it can be influenced by a(n) ______ (amount, variety) of factors.

• 分析：
  这里搭配的是“of factors”（……的因素）。
  “amount”用于不可数名词，而“factors”是可数名词复数，因此不能用“amount”。正确的量词是“a variety of + 可数名词复数”，表示“各种各样的……”。
  “a variety of factors” 是标准搭配，表示“多种因素”。

• 正确答案：variety

• 完整句子：...influenced by a variety of factors.

5. You could have chosen a much safer, less challenging ______ (topic, idea) for your first attempt at a novel.

• 分析：
  虽然“topic”和“idea”意思相近，但在“写小说”这个语境下，我们通常说“choose a topic for a novel”（选择小说的主题）。
  “idea”更泛泛，指“想法”，而“topic”更正式，更适合用于写作、研究、演讲等语境。
  此外，“less challenging topic”是更自然的搭配，强调主题的难度。

• 正确答案：topic

• 完整句子：You could have chosen a much safer, less challenging topic for your first attempt at a novel.

6. He ______ (deserves, wins) the reward for all the hard work he has done in the past decade.

• 分析：
  “wins the reward” 表示“赢得奖励”，强调通过竞争或结果获得。
  “deserves the reward” 表示“应得奖励”，强调基于努力、品德等道德上的合理性。
  句子中提到“for all the hard work he has done”（因为他过去十年的努力工作），这说明他理应得到奖励，强调的是“值得”，而不是“赢得比赛”。
  因此，“deserves”更合适。

• 正确答案：deserves

• 完整句子：He deserves the reward for all the hard work he has done in the past decade.

最终答案：

1. ongoing
2. expose
3. ounce
4. variety
5. topic
6. deserves

\boxed{1.\ ongoing,\ 2.\ expose,\ 3.\ ounce,\ 4.\ variety,\ 5.\ topic,\ 6.\ deserves}
