We first think of the traditional or nuclear family．This is a two-generation family,the father and the mother and their own children．Most couples wanted to have four children,two boys,two girls. Some nuclear families,however,may add one or more grandparents to come to live with them,that is three generations．This kind of family with grandparents,parents,and grandchildren is called an extended family．This family type was not very common during the later half of the twentieth century,but it's becoming more common now as an elderly grandparent moves in to live with a son or daughter．This is more possible now that American homes have become larger．What is interesting,however,is that after the grandchildren move out of the home and start their own families,this extended family shrinks back to a nuclear family,with just two generations again living together,a grandparent and parents,with the grandchildren coming only for occasional visits． Now,the fatherless or motherless family is one kind of what we call a single-parent family．In the fatherless family it's just the mother and her children．As I said,this can be the result of the husband's death,of an unmarried mother,of a separation or divorce．There are also a growing number of motherless families--where the father raises the children,for any of the same reasons．A motherless family may also be fatherless,but still a family with one adult．This is becoming more common in the big cities where a grandmother will raise her daughter's children while the daughter goes elsewhere to work. One other new kind of family is becoming increasingly more common．A single parent with one or more children will marry again．Perhaps the other parent is also a single parent．Together they will start what is called a blended family,which blends together or combines the children from two other families. What is true to the fact in America?
A、There are more and more members in a famil
B、There are less and less members in a famil
C、There is an increasing number of grandparents who refuse to look after their grandchildre
D、There is an increasing number of grandparents who live separately from their childre
【正确答案】：A
【题目解析】：根据文章描述，我们可以逐项分析选项： A. There are more and more members in a family（家庭成员越来越多）：文章描述了传统家庭（nuclear family）和扩展家庭（extended family）的概念，并指出随着祖父母搬来与子女同住，家庭成员数量增加。此外，还提到了单亲家庭（single-parent family）和混合家庭（blended family）的形成，这些家庭类型也通常包含更多的成员。因此，这个选项与文章描述相符。 B. There are less and less members in a family（家庭成员越来越少）：这个选项与文章描述不符，因为文章强调的是家庭成员数量的增加，而不是减少。 C. There is an increasing number of grandparents who refuse to look after their grandchildre（越来越多的祖父母拒绝照顾他们的孙子/孙女）：这个选项在文章中并未提及，文章描述的是祖父母搬来与子女同住，帮助他们照顾孙子/孙女的情况。 D. There is an increasing number of grandparents who live separately from their childre（越来越多的祖父母与他们的子女分开居住）：虽然文章提到了扩展家庭在20世纪后半叶不太常见，但现在由于房子变大了，祖父母更可能与子女同住。此外，文章并未强调祖父母与子女分开居住的趋势在增加。 综上所述，与文章描述最相符的选项是A，即家庭成员越来越多。
