【正文】 新材料成為其他高新技術(shù)發(fā)展的支撐和先導(dǎo)，其研究水平和產(chǎn)業(yè)化規(guī)模已成為衡量一個國家和地區(qū)經(jīng)濟(jì)發(fā)展、科技進(jìn)步和國防實力的重要標(biāo)志。 首先，新材料與新能源技術(shù)正在創(chuàng)造人類的個性化生活方式和生活理念。第三，新材 料與新能源技術(shù)對國際政治格局和人的政治生活的影響。隨著人們環(huán)保意識的增強(qiáng)，環(huán)境狀況逐漸成為人們對政府的態(tài)度或信任程度，以及個人行為選擇的重要指標(biāo)或影響因素。對核能安全的焦慮引發(fā)了公眾大規(guī)模的反抗運(yùn)動，而且，公眾日益強(qiáng)烈的反抗浪潮，已經(jīng)使得世界核電工業(yè)受到極大限制。 5為什么說地球的大氣圈、水圈和生物圈既是互相區(qū)別和相互獨(dú)立的，又是相互作用的？ 大氣圈是地球外圈中最外部的氣體圈層，存在于整個地球外層。地上天氣變化，氣候變異及溫室效應(yīng)都發(fā)生在大氣圈的對流層，且與自然界的水循環(huán)密切相關(guān)。氣態(tài)的水存在于大氣圈中（云層）；水圈是地球特有的環(huán)境優(yōu)勢，水圈的運(yùn)動和循環(huán)影響了地球上各種環(huán)境條件的變化，影響各個 圈層，是地球出于不斷的變換之中，特別是對設(shè)無權(quán)重的生命己任的生存與發(fā)展具有決定性意義。 位于大氣圈、水圈和巖石圈三者相鄰的界面。生物圈是一個和大氣圈層、水圈甚至地殼交織在一起的圈層，她也是大氣 =水河地殼長期演化，相互作用的結(jié)果，她參與了對巖石、大氣河水等其它圈層的改造，對地表物質(zhì)的循環(huán)、能量的轉(zhuǎn)換和積聚具有特殊作用。 談?wù)勀銓W(wǎng)絡(luò)道德問題的看法。在真實的社會，個體的人一舉一動都在眾人的 “監(jiān)視 ”之下，人們要顧及自己的身份、地位、角色，所以對自己的行為進(jìn)行了自覺和不自覺的約束和控制，這就是道德行為產(chǎn)生的主要原因。這種極端個人化的境況，容易使人暴露出自私、貪婪、欺騙的本性。當(dāng)人們卸去了現(xiàn)實生活中的粉飾，再把 自己的身心投入到虛擬的世界時，人們是以一種匿名的方式出現(xiàn)在網(wǎng)絡(luò)社會上的，容易淡忘自己的責(zé)任和義務(wù)。于是，一切在現(xiàn)實社會中視為離經(jīng)叛道、另類甚至卑鄙齷齪的事都可以在網(wǎng)上為所欲為，大放厥詞。 網(wǎng)絡(luò)道德失范特別嚴(yán)重影響了青少年的成長。青少年學(xué)生較難完全協(xié)調(diào)好網(wǎng)上與網(wǎng)下的關(guān)系，他們對自己在現(xiàn)實社會與網(wǎng)絡(luò)社會的道德要求不一樣，實行的是雙重道德標(biāo)準(zhǔn)。 4 Visafree policy brings Chengdu biz, tourism boost. Making national headlines several times, Chengdu39。s level of internationalization. The policy will also bring direct economic revenue, Li said.

My life was like a running race moving from place to place. I also lived in Beijing and Shanghai before, she said. But Chengdu is a pla ce that you never want to leave once settling down. It is now my second hometown, she said.
