答案以及解析
一、单选题
1．答案：C
句意：大约两百万年前，这里没有人类。考查数词。million百万，前面要用具体数字不用复数，即“基数词+million”；millions of“数以百万计”，前面不能加具体数字。millions of前不加about。故选C。
2．答案：A
解析：句意：你如何正确地读数字6,425,200？考查数词用法。根据数字的读法：十位和个位之间要加连字符；百位和十位之间加and，其它不用加and；million/hundred/thousand等表示单位的数量词前有具体数字时，不能加s；所以，6, 425, 200 读作Six million four hundred and twenty-five thousand two hundred。故选A。
3．答案：A
解析：build...up建立，增强；send...up 提出，使上升；pick...up捡起，学会.句意：每天最少做一个小时的锻炼有助于增强我们的体质。故选A。

解析：句意：她从来不和外国人说话，是吗？不，她和积极，能流利的说英语。反义疑问句的基本形式有两种：1、肯定陈述句加简略否定问句,2否定陈述句加简略肯定问句。反义疑问句的疑问部分的谓语动词与陈述部分的时态保持一致。never,从不，是否定词。故陈述部分是否定句。根据句子的结构是现在完成时态，故选B。
5．答案：D
解析：句意：孩子们经常在周末去博物馆。他们可以在那里学习科学、历史或艺术。考查名词辨析。banks银行；churches教堂；squares广场；museums博物馆。根据“They can learn science, history or art there.”可知，可以在博物馆学习科学、历史或艺术。故选D。
