【W(wǎng)hat】本板塊語篇的話題是“可再生能源”，介紹了可再生能源的相關(guān)知識(shí)，包括其種類、優(yōu)點(diǎn)、應(yīng)用現(xiàn)狀、面臨的挑戰(zhàn)及可能的解決方法，并提出可再生能源能夠讓未來世界更加綠色、健康。

【W(wǎng)hy】本文旨在增進(jìn)學(xué)生對(duì)可再生能源的認(rèn)識(shí)和了解，理解中國在這方面獲得的成就，以及開發(fā)利用可再生能源面臨的一系列挑戰(zhàn)和相應(yīng)的解決方法，幫助我們認(rèn)識(shí)到開發(fā)可再生能源對(duì)人類社會(huì)和自然環(huán)境的重要意義，從而培養(yǎng)我們的社會(huì)責(zé)任感?！綡ow】本文是一篇紀(jì)錄片文字稿，文章結(jié)構(gòu)清晰，主線分明，語言精煉且通俗易懂。全文共有六個(gè)自然段。第一段用一個(gè)想象的場(chǎng)景引入主題，將過去富饒、美麗的村莊與煤炭過度開采后廢棄的村莊進(jìn)行對(duì)比；第二至第五段為文章的主體部分，分別介紹了可再生能源的種類、優(yōu)點(diǎn)、應(yīng)用現(xiàn)狀、面臨的挑戰(zhàn)和可能的解決方法；最后一段總結(jié)全文，提出如果可再生能源能夠成為主流，那么未來的世界會(huì)更加綠色、健康。本文使用場(chǎng)景描繪的手法引入主題，更具代入感。在闡述可再生能源的優(yōu)點(diǎn)時(shí)，本文運(yùn)用了作比較的寫作手法。本文還使用了數(shù)據(jù)和例證來增強(qiáng)科學(xué)性、權(quán)威性和說服力?！?教學(xué)目標(biāo)
