根据短文内容,从短文后的选项中选出能填入空白处的最佳选项.选项中有两项为多余选项。

     I was interested in reading a newspaper article about a new concept in old people's homes in France.

The idea is simple, but revolutionary - combining a residential home for the elderly with a nursery school

in the same building.   1   In the afternoon, the residents enjoy reading or telling stories to the children, and

if a child is feeling sad or tired, there is always a kind lap to sit on and a cuddle (拥抱). There are trips

out and birthday parties too.

       2   The children are happy because they get a lot more individual attention, and respond well

because someone has time for them. They see illness and death and learn to accept them. The residents

are happy because they feel useful and needed. They are more active and more interested in life when the

children are around and they take more interest in their appearance too.

       3   There are many reasons for this, including the breakdown of the extended family, working parents with no time to care for aging relations, families that have moved away, and smaller flats with no room for

grandparents. But the result is the same-increasing numbers of children without grandparents and old

people who have no contact with children. And more old people who are lonely and feel useless, along

with more and more families with young children who desperately need more support.  4   

     That's why intergenerational programmes, designed to bring the old and the young together, are

growing in popularity all over the world.   5   Using young people to teach IT skills to older people is one

obvious example. Using old people as volunteer assistants in schools is another, perhaps reading with

children who need extra attention.

A. The advantages are enormous for everyone concerned.

B. There are examples of successful attempts all over the world.

C. Nowadays there is less and less contact between the old and the young.

D. However, there are some similarities between the old and the young

E. The children and the residents eat lunch together and share activities.

F. No previous experience can we use to communicate between them.

G. It's a major problem in many societies.
