摘要：The international Genetically Engineered Machine (iGEM) Foundation has continued to promote synthetic biology educationthroughout its 2021 competition. The 2021 Virtual iGEM Jamboree was the culmination of the competition’s growth, with 350projects from 7314 innovators globally. Collegiate, high school, and community lab teams applied their ideas to the Registry ofStandard Biological Parts, designing biological systems that provide solutions to an international scope of issues. Theenvironmental, diagnostics, and therapeutics tracks continue to be the most prevalent focal points for projects, as students deviseapproaches to detrimental impacts of climate change and the COVID-19 pandemic. The competition exemplifies high standards ofhuman practices, biosafety, and biosecurity through responsible biological engineering. As the iGEM Foundation continuespioneering STEM education into the future, equal developments of the competition’s economic accessibility, global diversity, andlong-term impact are necessary to allow a larger range of thinkers to access the power of synthetic biology.

摘要：许多本友埋怨,每当打开本本浏览网页时,总是会自动打开默认广告首页,或莫名其妙弹出奇怪的广告窗口,而每次修改后都会自动还原为广告网页。显然,这可以判断本本被＂绑架＂了,这不仅严重影响上网体验,在3G/4G模式下还会让流量白白＂流失＂,浪费钱。

摘要：goto语句它给程序设计带来方便灵活的同时,使程序流程变得混乱不堪。Java对语言框架做的重大改进之一就是抛弃了goto语句,取而代之的是两条特殊的流程控制语句——break语句和continue语句。本文具体分析了在什么情况下,如何使用这两种流程控制语句。

摘要：Birds are some of the few animals stil living in our cities,and I began this project because I thought that it was important to make sure that they can continue to live here.背景链接:在过去七年里,丹麦艺术家Thomas Dambo利用废弃的木料在世界各地建造了3500多个鸟舍。这些鸟舍不仅用材环保,而且色彩鲜艳、外形新颖,颇具童趣。以上是T homas对自己为什么这么做的解释。

摘要：一、何为"4C教学法"乐高教育在皮亚杰建构论的理念基础上,根据儿童获取知识的过程和学习效果,从而设计了"4C"教学模式,即由:联系(connect)、建构(construct)、反思(contemplate)和延续(continue)等四个过程组成的教学模式。联系-Connect:教师将学生已有的知识、兴趣与课标、知识点进行联系,让学生面临一个开放式的挑战或任务,将置身于问题解决方案寻找者的角色。
