(答案→)B
解析：
【小题1】B 空格所在的句子意为“很少有人能同样熟练地使用两只手。”either表示两者中任何一个，all指三者以上的全部，都不合文意。如果选two，则是two of our hands ，言外之意是人类有三只或三只以上的手，也应排除。
【小题1】D out of为固定搭配，意为“从(若干)中，(若干)里头有”。此句意为“每百人中有五人”。
【小题1】A 根据第一个空格的解所，可排除选项C和D。neither表示“两者都不”，而该句意为“新生儿能用任何一只手抓握物体”，只有either合题意。
【小题1】C 由转折连词but判断，后一句是对前一句的否定，即不再任意用一只手，而是改为固定地用一只手。而前文又交代了多数人习惯用右手，故填right.
【小题1】B 上文讲述的是儿童生理发展过程中的两种现象，具有普遍性，用一般现在时。
【小题1】D 人、猴近亲是常识。close作形容词，表示“距离或关系”的接近或亲近。
【小题1】A 猴也有两只手，表示“两者中的另—个”用the other.
【小题1】B 本空应是指代前面的 monkeys , 不仅指“猴子”，还应用复数，因此只能选B。
【小题1】C 表示“观察，注视”用watch。
【小题1】D 句子意为“大多数人习惯于用右手，这也给左撇子们的生活带来不便。”
