Have you ever wondered why birds sing? Maybe you thought that they were just happy. After all, you probably sing or whistle when you are happy. Some scientists believe that birds do sing some of the time just because they are happy. However, they sing most of the time for a very different reason. Their singing is actually a warning to other birds to stay out of their territory.D o you know whata “territory”is?A territory is an area that an an- im al,usually the m ale,claim s(声称)as its ow… 相似文献

Too clever by half is not a phrase used much in current management thinking, but it lurks beneath the surface of all modern organisations. One of the more interesting conclusions reached by the Japanese investigators of the nuclear accident at Tokaimura is that the technicians responsible for the processes at the plant let their high 1Qs get in the way of common sense. In their single-mindedness about cutting through inefficiencies that were blocking the plant's productivity, they lost touch with the overriding need to put safety first. 相似文献

As a trend of thought in literature and art,aestheticism rose suddenly at the end of the 19th century and withered away soon.It was just like a flash in the world of literature and art.One of the initiators,Oscar Wilde,has been noticed with great attention by the critics.Wilde earnestly practiced the aestheticism he advocated.Some of his acts were cast aside by the moral in his time,which at last led to his death in a strange land. 相似文献

INTRODUCTION One main purpose of requirements is to de-scribe the functionality of software. Thus re-quirements often serve as a basis for contracts aswell as for communication between customers anddevelopers. However, they are usually captured innatural language accompanied by a few top-levelinformal drawings like use cases or activity dia-grams that denote the structure of the functional-ities in an abstract way. One disadvantage of naturallanguage is that the developer has to cope with… 相似文献

In the Albanian schools settings does not exist religious discrimination, neither gender discrimination, but there exists a discrimination, as unfair against children called ＂difficulty＂. The children who drop out of school are by far less numerous compared with those who start school, but who are not properly treated, so that they can progress the same as other children. The object of this article is the children with learning difficulties, the causes of these difficulties. One of the reasons, among many others, why this secret dropping out of school happens is also difficulty in learning that quite a few number of pupils have, which are not known to everyone, and consequently are not treated by all the teachers, or by the other people who surround the child, condemning him to a school failure and slim chances to succeed later in life. It has often been pointed out that to define the causes of these learning difficulties it is not an easy task. A large number of factors intermingle bringing about the hell of learning for some children. If it is impossible to intervene in different organic damages （even they in many cases can be prevented though）, at least those depending on people can be avoided by offering a favorable environment, showing fondness towards them and making efforts to help these children. Above all, the authors have to be willing, to know and be able to do this as parents and precisely as teachers. 相似文献

The world's most widely used insecticides may delay the migrations of songbirds and hurt their chances of mating.In the first experiment to track the effects of a neonicotinoid on birds in the wild,scientists captured 24 white-crowned sparrows as they migrated north from Mexico and the southern United States to Canada and Alaska.The team fed half of those birds with a low dose of the commonly used agricultural insecticide imidacloprid and the other half with a slightly higher dose.An additional 12 birds were captured and dosed with sunflower oil,but no pesticide. 相似文献

Based on a case study,this paper explores the reason of the formation of the gender role and various negative stereotypes imposed on females by the patriarchal society,and attempts to analyze the painful experiences,physically and mentally,that females have to undergo both at home and out at work and to reveal the harmful influences that have been exerted upon the development of society by the prescribed gender role and negative stereotypes which virtually make females suffer throughout history.This paper also reveals a big irony:while various biases imposed by society victimize females,they also victimize society itself.Therefore,the paper argues that the only way out is to establish a new cycle which will undermine the structural basis for traditional views of male and female roles. 相似文献

Last time we talked about baby animals such as pups of dogs, kittens of cats, chicks of chickens, and ducklings of ducks. As I sat down to write this column, I saw some of my old squlrrelsI friends sneaking into my backyard and climbing onto the bird feeder2 to steal bird food again. They are cute but can also be a big headache, because they scare the birds a way and they eat a lot. They can finish within an hour the monthly supply that I put out for the birds. These squirrels must also be taking some of the food back to their babies, and I am wondering--what are baby squirrels called？ Ah, they are called--are you ready-- pups or kittens, just like baby dogs and cats. 相似文献

In April 2004, it came to Beijing for the first time. The opera tells us that 2 . One day, they decided to choose a cat to go to paradise(乐园). So each of the cats introduced himself and showed himself. 3 . At last, a very old cat came out. She sang a song called Memory. She sang, "...Memory, all alone in the midnight.

At the end of the opera, the cats chose the old cat to go to paradise. 5 . I like it very much. 相似文献
