Finish Exercise 4 on Page 15 of the textbook.A smart home is one that integrated computers into the structure of the building itself. In this way, many of the things that we now do ourselves become automatic. For example, the smart home could control the air conditioning and lights so that you would no longer have to turn switches on and off, and so that your home would be more energy-efficient. The smart home could also monitor itself to make sure that everything is working as it should, and send you warnings if there is a problem. Such smart homes could even be programmed to detect your health problems, and then give you reasonable advice as to the food you should eat or if you should see a doctor. So, in a sense, smart homes will lead us to living smarter lives.2.Create a smart function for your home, and share your creation in the next period.

【轉(zhuǎn)折過渡】除了以上所說的褶皺山和斷層山之 外,是否還有其他類型的山脈呢?試舉一例說明?!緦W(xué)生思考后回答】有,如富士山屬于火山?!窘處熆偨Y(jié)】同學(xué)們回答的很好,還有火山,那么火山是如何形成的呢?這就是我們要研究的下一個(gè)問題。【板書】3、火山【指導(dǎo)讀書】請同學(xué)們閱讀教材P81思考:①玄武巖高原和火山有什么聯(lián)系與區(qū)別? ②火山由哪幾部分構(gòu)成的?③火山的規(guī)模是否相同?【學(xué)生回答】①聯(lián)系:玄武巖高原和火山都是由于處于地下深處的巖漿,在巨大的壓力作用下,有時(shí)候會沿著地殼的薄弱地帶噴出地表而形成的。區(qū)別:玄武巖高原是巖漿沿著地殼的線狀裂隙流出,往往比較寬廣。如哥倫比亞高原。火山是巖漿沿著地殼的中央噴出口或管道噴出。如我國長白山的主峰。②火山由火山口和火山錐兩部分組成。③火山的規(guī)模大小不一,大火山的相對高度可達(dá)4 000~5 000米,火山口直徑為數(shù)百米;小火山的相對高度不及100米。
當(dāng)時(shí),不只發(fā)生了太陽風(fēng)暴,同時(shí)還有其它的現(xiàn)象發(fā)生,導(dǎo)致災(zāi)難巨大。 如果,這些現(xiàn)象單獨(dú)地發(fā)生,結(jié)果就會是另外一個(gè)樣子。正是由于這些因素綜合起來,1859年的太陽風(fēng)暴,才在人類歷史上留下了濃墨重彩的一筆。太陽磁暴開始干擾通信日本衛(wèi)星首個(gè)被“擊中”日本航天機(jī)構(gòu)29日聲明,受強(qiáng)烈的太陽磁暴影響,28日晚,日本“兒玉(Kodama)”通訊衛(wèi)星信號中斷。 據(jù)美聯(lián)社報(bào)道,在太陽黑子活動減弱后,“兒玉”通訊衛(wèi)星恢復(fù)正常運(yùn)轉(zhuǎn)。 美歐研究人員28日發(fā)布新聞公告稱,太陽當(dāng)天發(fā)生了一次強(qiáng)烈的耀斑爆發(fā),預(yù)示著新一輪太陽風(fēng)暴將在今后一兩天內(nèi)抵達(dá)地球,地球上的通信等設(shè)施可能會因此受到部分干擾。與這次耀斑爆發(fā)相伴,太陽表面還產(chǎn)生了一股強(qiáng)大的日冕物質(zhì)噴射,方向幾乎直沖地球。研究人員說,噴射產(chǎn)生的帶電粒子流正以約每小時(shí)750萬公里的速度奔地球而來,其與地球磁場作用后可能會形成比較強(qiáng)烈的地磁暴,使地球兩極出現(xiàn)極光,并可能對衛(wèi)星運(yùn)行和通信等造成干擾。
