The following figure shows the push-in stack:The research on classification ability is more in kindergartens and more in primary schools. Research by cognitive psychologists has found that children under 0-1 years old basically have no classification ability, and they mainly rely on individual perception. The classification ability of children aged 1-3 has begun to sprout, but the concept of "category" has not yet formed. The classification of children aged 3-5 is basically still based on external perceptible dimensions such as shape and color. For example, children in small classes in kindergartens are asked to classify red plastic balls, red apples and bananas. They will divide the balls and apples together, either according to the shape (circle) or according to the color (red), but they will not put apple kernel bananas together according to the function (edible). What if you add another celery?9. December-February in winter, By this time the lobsters had all entered the cave to escape the cold. By this time lobster was already in short supply, It was the highest price of the year, Our situation on the ground is that, By this time, Some idle people took shovels and dug holes everywhere to catch lobsters. At this time, there is usually no water in the pond. Lobster holes are all on the shore, An experienced person can see the lobster hole at a glance. At this time, some of them can be caught and sold. The price is generally twice that of summer. Of course, lobsters with eggs should be put back. It is said above that they basically hatch in October. Why are there still lobsters with eggs at this time? It is because lobsters are of different sizes and do not mature sexually at the same time. At this time, lobsters usually do not hatch until March of the following year because of the low temperature. Our local price at this time is: Lobster with mud collected 18-20% last year, basically with half of the mud, which is about 30 yuan. Taking mud in winter makes people feel that it was dug out of the hole. Even if it is not, it will be pasted with mud, which is basically a hidden rule. Just like selling crabs with ropes, selling 70 people without ropes is too expensive. Taking a few taels of ropes and lowering the price will make it easier for people to accept it.而且这韩信某种程度上是和自己的利益联系在一起的，没必要因此去得罪一位汉国举足轻重的元帅。李敬文摇摇头，看着她轻声道：我那年不是说，中了秀才要请你们吃饭么。小朋友，能不能别笑了，要表现出很生气。故事发生在2006年，苏莯是一位临时演员，平日里接一些不起眼的角色维持生活，但苏莯坚持着自己的演员梦想，虽然辛苦但自己觉得值得。某日，苏莯在公交车站躲雨，一个质朴漂亮的女孩林一一出现在苏莯面前，林一一没有拿雨伞似乎很着急，苏莯鼓起勇气为林一一撑起了伞，两个人确定了关系。转眼来到了2008年，苏莯和林一一还有几个好朋友一起吃着火锅，看着奥运会开幕式，小酌几杯。喝的兴起，苏莯开始谈天说地，告诉大家未来一定会和林一一过的很幸福。此时，旁边桌坐着一位奇怪的大叔，听到了这一切，把苏莯叫到了旁边，询问他是否想看一看未来自己的生活。苏莯表示好奇，喝了酒的苏莯似乎有些醉意，但大叔说他有能力让苏莯跨越时空去见到未来的生活……
