易错题解析：
3. In paragraph 1, what does the author imply about changes in the African environment during this time period?
○The climate was becoming milder, allowing for a greater variety of crops to be grown.
○Although periods of drying forced people south, they returned once their food supply was secure.
○Population growth along rivers and lakes was dramatically decreasing the availability of fish.
○A region that had once supported many people was becoming a desert where few could survive.
题型：推论题。答案是(D)
解析：以changes of African environment做关键词定位至原文第三句” The drying up of what is now the Sahara desert had pushed many peoples to the south into sub-Sahara Africa.”，注意题目中的关键词原文没有，但原文中的drying up of what is now the Sahara desert就是一个环境变化。说干旱把这些人赶到了撒哈拉以南地区，也就是说这个变化使得他们原来住的地方不能住了，所以D正确。
语法点：介词短语做后置定语
Paragraph 5: Unlike in the Americas, where metallurgy was a very late and limited development, Africans had iron from a relatively early date, developing ingenious furnaces to produce the high heat needed for production and to control the amount of air that reached the carbon and iron ore necessary for making iron.Much of Africa moved right into the Iron Age, taking the basic technology and adapting it to local conditions and resources.
10. Which of the sentences below best expresses the essential information in the highlighted sentence in the passage? Incorrect choices change the meaning in important ways or leave out essential information.
○While American iron makers developed the latest furnaces, African iron makers continued using earlier techniques.
○Africans produced iron much earlier than Americans, inventing technologically sophisticated heating systems.
○Iron making developed earlier in Africa than in the Americas because of the ready availability of carbon and iron ore.
○Both Africa and the Americas developed the capacity for making iron early, but African metallurgy developed at a slower rate.
题型：句子简化题。答案是(B)
解析：本句的主干是，和美洲不同，非洲人制铁比较早，后面自developing开始是状语后置，表明非洲人制铁较早的原因是发明了ingenious furnaces,(熔炉)原句包含一种对比关系，即非洲人比美洲人制铁要早。
语法点：现在分词作时间状语、定语从句的用法。
