，只要沒有新物質(zhì)產(chǎn)生就不是化學(xué)變化。由此得知：判斷是化學(xué)變化還是物理變化的依據(jù)是看是否有新物質(zhì)產(chǎn)生。4．解析：選B細(xì)節(jié)理解題。根據(jù)第二段可知：把水分解成氫氣和氧氣，是一個化學(xué)變化。語篇解讀：文章向我們介紹了如何做簡單且有趣的科學(xué)實(shí)驗(yàn)。5．解析：選D作者意圖題。通讀全文，可知作者主要向我們介紹怎么做一個簡單而有趣的科學(xué)實(shí)驗(yàn)，故選D。6．解析：選B推理判斷題。根據(jù)第一段的“Onesuchexperimentistoshowyourfriendsandteachersthatyoucanmakemothballs(樟腦丸)dance！”可知選“跳舞的樟腦丸”最好。7．解析：選D細(xì)節(jié)理解題。根據(jù)第
