4. A。主旨大意题。本文主要讲述了什么才是真正的聪明这一话题。故答案为A。B、C、D项过于片面。

3. C。推理判断题。根据文章最后一段最后两句可知，聪明的孩子想真正了解生活，他努力接触身边的一切事物；而不聪明的孩子则脱离生活，让自己的生活限制在一个封闭和自我梦境的世界里。他们对待生活的态度是截然不同的，由此可推知C项正确。

2. C。细节理解题。根据文章第二段第一句For example, when in a new situation, an intelligent person thinks about the situation, not about himself or what might happen to him.可知C项正确，且可以排除A、D两项；根据文章第二段第三句He probably isn’t sure how it will all work out, but at least he tries.可排除B项。

1. C。细节理解题。A项中的immediately与原文的意思有出入；根据文章第一段第一句When we talk about intelligence, we do not mean the ability to get good scores in certain kinds of tests or even the ability to do well in school.可知，聪明并非意味着在某些考试中得高分或者在学校学习好，由此排除B项；由第一段最后一句可知D项不正确；由文章第一段第二句By intelligence we mean a way of living and behaving, especially in a new or anxious situation.可知C项正确：聪明指的是处理生活中实际事物的能力。
