Finally, the writer combined the paper with the request of our country"s current education development to the new period teaching material reforms, concern with the future of our country"s teaching material reforms of chemistry, put forward several suggestions about our country"s teaching material reforms of chemistry: The spirit of teaching material should return to human; teaching material target should more characterful, socializing and more popular; the developing in the flexibility of the teaching material contents ; teaching and learning method"s type in the book should be investigable, cooperant and interactional; teaching material"s diversification"s and modernizations trend etc.

最后，笔者结合目前我国教育发展对新时期教材改革的要求，关注于我国基础教育中的化学教材改革的未来，提出了对我国高中化学教材改革方向的几点展望：教材编制指导思想的&人本化&发展；教材教学目标中的素质化、社会化、大众化的转变；教材内容的弹性化发展；教材的教法、学法的探究式、合作式、互动式转变；教材载体的多元化、现代化趋势等等。

Negli ultimi minuti del match il Real Franciacorta va spesso vicino al goal con Chinotti, che al 30′ viene steso in area: il rigore appare netto a tutti , ma l'arbitro fa continuare il gioco, scatenando le proteste di tutta la panchina ospite.

在最后几分钟的比赛往往是真实Franciacorta附近的目标Chinotti其中30 '是中规定的面积：严谨似乎每个人都清楚，但主裁判是继续比赛，引发抗议板凳东道国。

Or new discoveries in cures for some human Diseases The well-known history of the Revolution in 1911 is a good example through a hard struggle with many failures for almost three decades, Dr. Sun Yat-sen with his people free themselves from a corruptive government of the last dynasty likewise if one wants to succeed in pursuing his serious goal in his life, perseverance is always the necessary characteristic he should learn to have.

或新发现的治疗人类疾病的一些著名的历史，辛亥革命是一个很好的例子，通过艰苦奋斗与许多失败的近30年来，孙中山与他的人民摆脱了腐败的政府最后王朝同样如果想成功地推行他的认真，他的生活目标，毅力始终是必要的特性，他要学习的。

Firstly, 3-ethylthiobutanal was prepared from crotonaldehyde reacting with ethanehiol in triethylamine with high yield. Secondly, methyl acetoacetate was converted to 6-ethylthiohept-3-en-2-one by three steps via hydrolysis, condensation with 3-ethyltio-butanal and dehydration, then 6-ethylthiohept-3-en-2-one was cycloco ndensed with dimethyl malonate by Michael addition and Claisen condensation, followed by saponification and decarboxylation to give the intermediate of 5-(2-ethylthiopropyl)-cyclohexane-1,3-dione.
