In Britain, in a population of 60 million, there are 13 million grandparents, many of whom live alone a long way from their grandchildren.The loneliness of these older people has become an issue that schools are trying to teach children about .

On a popular teacher’s website, there is a classroom activity to help make children aware of the implications of the different generations of the same family living far from each other. It’s a story about Mrs. Eiderdown, an elderly lady whose grandchildren have moved to Australia with their parents. She lives alone and rarely sees her family .

First of all, the children speculate about Mrs. Eiderdown’s life.  What does she have for breakfast ? what does she do all day ?how does she feel about her life ?

One day, Mrs. Eiderdown decides that she wants a pet to keep her company and puts an advertisement in a local shop window. Then she waits at home to see if anyone will answer her advertisement .

A tall thin man rings her doorbell. he is holding a cardboard box. Mrs. Eiderdown chats with the man for ten minutes before she realizes that she hasn’t looked in-side the box to see what the pet is. She can hear a his-sing sound. The children guess what is in the box(a snake). Mrs. Eiderdown thanks the man but says she doesn’t think the snake is a good idea .

The next time the doorbell rings, there’s a lady on the doorstep, also carrying a cardboard box.In the bottom of the box, Mrs. Eiderdown sees something black and hairy with eight legs. Again ,the children say what they  think it is (a spider). Mrs. Eiderdown thanks the lady for her kindness but says that a spider is not the sort of pet she has in mind.

At last, the little girl next door brings her a dog .Mrs. Eiderdown’s life improves a lot because of the dog. more importantly, of course, the little girl, whose own granny lives a long way away, starts to visit Mrs.Eiderdown more often. This interactive classroom idea has led to a greater awareness among children about the possible loneliness of older people who live quite near them .

位于黄石国家公园的大棱镜温泉(又称大虹彩温泉),是美国最大、世界第三大的温泉。大棱镜温泉的美在于湖面的颜色随季节而改变。春季,湖面从绿色变为灿烂的橙红色,这是由于富含矿物质的水体中生活着的藻类和含色素的细菌等微生物,它们体内的叶绿素和胡萝卜素的比例会随季节变换而改变,于是水体也就呈现出不同的色彩。
