题干二、阅读理解：判断正误题（每题10分） Extended family In an extended family, all the people share one household. Apart from parents and children, there may be other family members: grandparents, aunts, uncles, cousins, etc. That is to say, a large family may have more than two generations, and often there are more than two adults from different generations of a family. The family members live together for many reasons. They may help to bring up children or to take care of an ill relative. They may also help with saving money. Sometimes children are brought up by their grandparents, for their parents have died or can never take care of them. Many grandparents look after the children, particularly when both parents are busy working. This large family is called extended family. It can be found all over the world. The number of these families has increased by 40 percent in the past ten years. Most of such families live happily together. 操作提示：句子正确选择下拉选项框为“T”；句子错误选择下拉选项框为“F”。 1.

Children can live happily with their parents and grandparents. 回答TF未回答正确答案是：T获得10.00分中的0.00分反馈解析：1. 这是一道细节题。第二句话提到“all the people share one household”（所有成员都住在一栋房子里）。由此可知，题目中“住在不同的房子里”的表述是错误的。2. 这是一道细节题。课文中提到“more than two generations”意思是“超过两代人”，因此，题目中“至少三代人”的说法是正确的。3. 这是一道推理题。从文章第二段中可以看到，祖父母照顾孩子的原因多种多样。题目中提到父母因为旅游（travel around）而将孩子托付给祖父母照看这一点文中并没有出现。因此，该说法错误。4. 这是一道细节题。参见倒数第三句话。5. 这是一道推理题。从最后一句话中我们知道，大部分大家庭都很幸福，因此可以推知题目中的表述是正确的。人文英语1
