【分析】本题为英语阅读理解选择题，解题思路为：先通读短文把握主旨，再针对每个小题的问题，定位原文对应内容，逐一匹配选项得出答案。第1题需定位天气变化的季节；第2题找早上的天气描述；第3题结合上下文猜测划线词词义；第4题概括短文主旨选最佳标题。
【解析】1. 定位原文第一段“In this place, the weather changes a lot in summer.”，可知青藏高原夏天天气变化大，对应选项A；2. 定位“Spring morning”段落第一句“The Qinghai-Xizang Plateau has a warm morning.”，可知早上天气温暖，对应选项C；3. 原文提到“the sun goes down, the temperature goes down”，太阳落下后下降的是温度，故“temperature”意为“温度”，对应选项B；4. 短文围绕青藏高原夏天的天气变化展开，分早、午、下午、夜四个时段描述，对应选项B“青藏高原夏天的天气变化”，A选项“四季”不符合原文（是一天内的变化），C选项“寒冷”片面。
