2019-2020年高中英语必修四:unit3 H-G- Wells 教案H.G. Wells is considered by some to be the father of modern science fiction.BiographyHerbert George Wells was born in 1866 in Bromley, Kent. His career as an author was fostered by an unfortunate accident as a child. He broke his leg and spent the mandatory rest period reading every book which he could find. Wells was awarded a scholarship and furthered his education at the Normal School of Science in London. It was at the Normal School that Wells came under the wing of the famous biologist Thomas H. Huxley. Wells' "science fiction" (although he never called it such)was clearly influenced by his studies at the Normal School and his interest in biology.H.G. Wells gained fame with his first major fiction work: The Time Machine in 1895. Soon after the publication of this book, Wells followed with The Island of Dr. Moreau (1895), The Invisible Man (1897), and perhaps his most famous popular work: The War of the Worlds (1898).Over the years Wells became concerned with the fa te of human society in a world wher e technology and scientific study were advancing at a rapid pace. For a period he was a member of The Fabian Society, a group of social philosophers in London. Wells's later works became less science fiction and more social critique.The accuracy of the "science" in Wells's work has often been called into question. It is rumored that Wells and the French novelist Jules Verne actually criticized each other's writing. Wells's claim was that "Verne couldn't write himself out of a paper sack" and Verne accused Wells of having "scientifically implausible ideas." The science may not be accurate, but the adventure and philosophy in those books makes Wells' e arly science fiction fun and fascinating to read.The major works of H.G. Wells∙The Invisible Man∙The War of the Worlds∙The Island of Doctor Moreau∙The Time MachineThe First Men in the Moon。

高一英语导学案必修二四单元作文英文回答:There are several key factors that contribute to the success of a teenage relationship. Firstly, open and honest communication is crucial. Teenagers should feel comfortable sharing their thoughts, feelings, and concerns with their partner without fear of judgment. Secondly, trust is essential in any relationship, and this is especially true for teenagers who may be experiencing strong emotions for the first time. Both partners should feel they can rely on each other and that their secrets are safe. Thirdly, respect is another important factor. Teenagers should treat their partner with kindness and consideration, even when they disagree. Finally, it is important for teenagers to have realistic expectations about their relationship. They should not expect perfection, and they should be prepared to work through any challenges that arise.中文回答:对于青少年来说,一段成功的恋爱关系需要具备以下几个关键因素:1. 开放而诚实的沟通,青少年应该能够舒适地在没有评判的情况下与伴侣分享他们的想法、感受和担忧。
