She brought her characters to life in b witty stories with finely detailed watercolors. a Br herit The daughter of wealthy parents, Helen Beatrix Potter was born on July 28, 1866 in South Kensington, London. She was educated at home and developed a love of literature and art. She used to practice her craft bv making illustrations for fairy tales like Cinderella and Sleeping Beauty. Also drawn to nature, she and her younger brother Walter kept many pets mice, rabbits, even bats and a hedgehog and she loved her family's long holidays in the Scottish countryside and the Lake District, a mountainous area in northwest England. in 19 The As a child and teenager, Potter made great sketches of her pets, as well as of trees and plants.

She wrote in a secret bs nsgst Peri 1866- Code that was not broken until fifteen years after her death. In the 1890s, Potter began selling her drawings.Potter's work was used for Christmas and New Year cards and an illustration of poetry. She was pleased by this success and decided to publish her own illustrated stories for children.

第3回 実戦問題 73 Vou are going to have a debate about men taking parental leave. In order to prepare for the debate, your group is reading the article below. According t0 a recent survey, about 5.14% of new fathers in Japan Love taken parental leave. Over the years, the number of men who take 18u0 narental leave has grown, but it is still a big challenge for men to take it in male-oriented-Japanese society. So, here is my question: Do you think more Japanese men should take parental leave or not? Taking parental leave has one great benefit. If men take it for even a couple of weeks after the baby arrives, it is a great help to their wives. Most families are now nuclear families, so it is more difficult for couples with a new child to get support from their parents. Husbands can provide not only physical support but also mental support to their wives. Since new mothers face many unexpected situations every day, they can feel a lot of stress. Getting help is the key to reducing it. Another benefit is that parental leave is usually refreshing for men, allowing them to work more efficiently after they return to their jobs. On the other hand, there are reasons men should not take it. (First, during parental leave, they get no salary. This can put a lot of pressure on family finances. Second, many people are still against men taking it, which places psychological pressure on the men who do. What do you think about this issue? Ibelieve that when men take parental leave, it helps them understand how hard caring for a baby is. Knowing more about the hard work of their wives surely strengthens their relationship. Furthermore, when men eagerly raise their children, Tamily bonds become stronger. Nobody could argue that such things should be not be encouraged. 第3回 don

There are actually two ways to season wood. r is to allow the natural drying process to occur. The other is to put it . cnecial oven called a kiln. Kiln drying is much faster than the natural method. During the seasoning process, water is removed from the wood until the moisture content of the wood is approximately equal to the humidity of the air around it. These changes in size due to shrinkage are not uniform because changes depend on the kinds of trees, the way trees are cut, and the surrounding conditions. It is also important to note that even after seasoning, there will always be Some small changes in size due to changes in the humidity of the surrounding air.
