答案与题解：
1. A 本题的问题是：在传统的农业经济中，大的家庭的影响是什么?从文中第二段第二句和第三句话可以得出明确的答案。“In a traditional agricultural economy， large families are helpful. Having more children means having more workers in the fields and someone to take care of the parents in old age.”所以答案为A，是优势。
2. B 本题的问题是：当国家工业化后，人口和出生率的状况是什么?从第二段意大利的例子可以明确得出答案。“In the early part of the twentieth century， Italy was a poor， largely agricultural country with a high birth rate. After World War Ⅱ， Italy’s economy was rapidly modernized and industrialized.”由此可见出生率降低。
3. C 本题的问题是：本文举出意大利的例子要说明什么?从第二段意大利的前后对比的情况可以看出正确答案为C.
4. B 本题的问题是：文中提到沙特阿拉伯的例子说明了什么?由第三段开头可知“However， the economy is not the only important factor that influences birth rate.”下面将要介绍其他的因素，之后以沙特阿拉伯为例。故正确答案为B.经济以外影响出生率的因素。
5. D本题的问题是：墨西哥、泰国、印度尼西亚的政府采取了怎样的措施?从文中第四段后半部分“On the other hand， the improved condition of women in Mexico， Thailand， and Indonesia explains the decline in birth rates in these countries. Their governments have taken measures to provide more education and opportunities for women.”可以得出结论。另一方面从第四段开头也可以得出结论。“The most important of these is the condition of women.”之后举出这几个国家的例子，从而也可以得出结论。
