(单选题)

What can we infer from Paragraph 5?

A.Hard times make us lose heart and be short of courage.

B.Perseverance in time of hardships develops our strengths.

C.Smiles when you fail will not help to improve yourself.

D.We should try to avoid failures in the evolutionary process.

参考答案：B

参考解析：

推理判断题。根据文章第五段第三、四句“Your struggles develop your strengths. When you go through hardships and decide not to give in, that is strength”可知，在艰难困苦中坚持而不放弃，可以让自己变得更强大，故B项正确。A项“艰难的岁月使我们灰心丧气，缺乏勇气”，C项“当你失败时，微笑不会帮助你改善自己”，D项“我们应该尽量避免在前进中出现失败”，均不符合文意。故选B。
