问题     Humans readily change tools to suit the circumstances: once a basic knowledge of tool-making has been acquired, it is a simple matter to make something more suitable for the job【C1】______ . So early people made not only hand axes for chopping, but also smaller knives and scraping tools with which to cut meat and【C2】______ fat off the skins.
    It is clear from archaeology that humans were【C3】______ from very early in history to exploit a much wider range of food resources than other【C4】______ . In particular they were frequently able to eat meat; the diet of apes is normally vegetarian(食草的), consisting of grass, leaves, and shoots,【C5】______ by insects and grubs. With tools such as spears and bows, early humans were able to【C6】______ larger animals. Spears and nooses(套索, 陷阱)could be used to catch birds and smaller animals,【C7】______ fish could be taken with nets and traps set on the river bottoms. Excavations(出土文物)made at the living sites of early people have revealed bones from the animals that they ate, while also providing【C8】______ of their ingenuity(精巧，独创性). Some of the bones found in the cave of Makapansgat in South Africa show signs of being【C9】______ broken and divided into types suitable for different purposes as tools. Tools also enabled humans to【C10】______ food in specially made containers of wood or baskets, so that times of shortage could be lived through more easily. [br] 【C4】
选项 A、animals
B、creatures
C、primitives
D、residents
答案 B
解析 空格所在部分的大意是：与其他——相比，人类有能力开发出更多更广的食物资源。这里一个比较关键的词是other，我们就此可以推测空格后的名词与humans应是同一类别。C项primitives(原始人)和D项residents(居民)显然不符合句意，可以首先排除。人和动物之间是没有交集的，若选A项animals，就没必要用other修饰了。B项creatures可以指人，也可以指动物，humans和animals都属于creatures。所以，正确的答案是B项creatures。
