n)莓醬的秘訣就是對(duì)人生的感悟。真正讓我們幸福的是和他人的關(guān)系以及與家人朋友一起度過(guò)的那些日子有關(guān)的回憶。因此，本文的最佳標(biāo)題應(yīng)為“藍(lán)莓醬食譜”。C【語(yǔ)篇解讀】本文是一篇說(shuō)明文，主題語(yǔ)境是科學(xué)與技術(shù)，主題語(yǔ)境內(nèi)容為科技發(fā)展。文章介紹了GeorgiaTech的研究者們想出了一種低成本的裝置——智能鍵盤(pán)，來(lái)保護(hù)私人的電子空間，并希望這種設(shè)備能盡快進(jìn)入市場(chǎng)，服務(wù)消費(fèi)者。本文側(cè)重培養(yǎng)學(xué)生的創(chuàng)
