我们来逐句分析并完成这道填空题。题目要求使用下面的单词填空，必要时改变词形：

提供的单词有：
reinforcement, comforting, decisive, evaluate,
baggage, worthless, underlying, manifest

第1句：
An excellent character is one of the key factors in studying a complex subject: Being insistent, confident and ____ are all important.

分析：
句子中列举了优秀品格的几个特质：“insistent（坚持的）”、“confident（自信的）”，以及一个空格。这三个词都是形容词，用来描述人的性格特征。我们需要从选项中找一个表示积极性格特质的形容词。

选项中符合这一语境的有：decisive（果断的），它和“insistent”、“confident”一样，都是描述优秀性格的形容词。

答案：decisive

完整句：Being insistent, confident and decisive are all important.

第2句：
It is important to assess your goals from time to time, ____ where you are and where you want to be, and plan accordingly.

分析：
句子结构是三个并列的动词不定式（省略to）：assess, ____, plan。因此空格处应填一个动词原形。

句意是：要定期评估目标，______你所在的位置和想去的地方，然后制定计划。

选项中表示“评估、判断”的动词是 evaluate，意思完全匹配。

答案：evaluate

完整句：...assess your goals..., evaluate where you are..., and plan accordingly.

第3句：
Time is precious, do not waste it on ____ deeds.

分析：
“deeds”是名词，意为“行为”，前面需要一个形容词修饰。句意是“时间宝贵，不要浪费在______的行为上”，显然是指“无价值的、无意义的”行为。

选项中，worthless（毫无价值的）正好符合。

答案：worthless

完整句：do not waste it on worthless deeds.

第4句：
Positive ____ carries a strong message for children, as those who receive praise for good acts try harder to behave.

分析：
空格在“Positive”之后，应为一个名词。句意是“积极的______对孩子有强烈的影响，受到表扬的孩子会更努力表现好。”

这里讲的是“表扬”或“正面强化”对孩子行为的影响。选项中 reinforcement（强化）是心理学中常用术语，特别是“positive reinforcement”（正向强化），是固定搭配。

答案：reinforcement

完整句：Positive reinforcement carries a strong message...

第5句：
Some psychologists say that the gene seems to be the ____ reason of some people's ability to deal with daily stresses.

分析：
空格修饰“reason”，需要一个形容词。句意是“基因似乎是某些人应对日常压力能力的______原因。”

这里强调的是“根本的、深层次的”原因，不是表面的。选项中 underlying（潜在的，根本的）正好符合。

答案：underlying

完整句：the gene seems to be the underlying reason...

第6句：
Every time I get bad grades, my best friend's ____ words never fail to make me better.

分析：
空格修饰“words（话语）”，需要一个形容词。句意是“每当我成绩不好，好朋友的______话语总能让我感觉好起来。”

能让人感觉好起来的话语，是“安慰性的”。选项中 comforting（令人安慰的）完全符合。

答案：comforting

完整句：my best friend's comforting words never fail to make me better.

第7句：
What you need now is a walk to clear your head while you try to let go of some emotional ____.

分析：
“emotional baggage”是固定搭配，意为“情感包袱”或“心理负担”，指过去的创伤、情绪负担等。选项中有 baggage，正好匹配。

虽然“manifest”是动词或形容词，但不符合此处名词位置；其他词也不如“baggage”贴切。

答案：baggage

完整句：let go of some emotional baggage.
