【分析】
这是一篇介绍恐龙相关知识的英语阅读理解题，解题时首先通读全文把握文章大意，再结合不同题型的要求逐一作答：1. 词义猜测题需要结合上下文语境+生活常识推导含义，恐龙早已灭绝，人类正是通过古生物遗留的化石了解恐龙的相关信息；2. 细节理解题和细节判断题，只需要回到原文定位对应描述，将选项/题干内容和原文表述逐一比对，就能判断正误选出答案。
【解析】
1. 定位原文第一段语境：恐龙数百万年前就生存在地球上，如今人类已经看不到活体恐龙，只能通过古生物的遗留物了解恐龙的相关信息，结合常识可知fossils的中文含义是化石，故选B。
2. 定位原文对霸王龙的描述："It likes eating meat. It is very big and dangerous...It weighs about 10 tons, and it is heavier than a bus"，A选项“喜欢吃蔬菜”和原文食肉的描述不符，B选项“又小又矮”和原文体型巨大的描述不符，C选项“又重又大”完全符合原文表述，故选C。
3. 原文第一段明确提到"And now we can't see them."，说明如今地球上已经看不到恐龙了，题干表述和原文矛盾，故答案为F。
4. 原文第二段直接给出霸王龙的特征描述"It is about 5 metres tall"，和题干表述完全一致，故答案为T。
5. 原文第二段提到部分小型恐龙"weigh 2 kilograms. They are even lighter than a dog"，说明这类恐龙比狗轻，也就是狗的体重可能超过这类恐龙，题干表述正确，故答案为T。
