SAT閱讀材料：如何制作太陽能熱水器.

　　下面澳際小編為大家整理一篇關(guān)于如何制作太陽能熱水器的SAT閱讀素材文章，供大家學(xué)習(xí)，大家平時(shí)也可以多關(guān)注和積累，自己搜集整理一些比較好的SAT閱讀考試素材，幫助自己更好地備考SAT閱讀考試。

　　每一篇SAT閱讀素材均有其主要觀點(diǎn)或中心主題。典型的圍繞文章主要觀點(diǎn)的問題大多是：在這篇文章中作者的主要目的是什么?這篇文章主要涉及什么問題?這篇文章主要建議是什么?這篇文章總體上想要回答什么問題等。讀完每一篇SAT閱讀素材，我們都要針對(duì)SAT素材想想這幾個(gè)問題。

　　Solar water heaters are used around the world and are not very difficult to build. The system we are going to describe is based on a design developed some

　　years ago in Afghanistan. Since then, it has been built and used in many countries.

　　太陽能熱水器應(yīng)用于世界各地，也不難建造。我們將要講述的這種太陽能熱水器系統(tǒng)是基于幾年前阿富汗開發(fā)的一種設(shè)計(jì)。從那時(shí)起，許多國家建成并使用這種太陽能熱水器。

　　It can heat seventy liters of water to sixty degrees Celsius. It can do this between sunrise and noon on a clear day with an average air temperature of

　　thirty-two degrees Celsius.

　　它可以在晴天有日照，平均氣溫在攝氏32度的天氣里，將70升水加熱到攝氏60度。

　　There are two parts to the solar water heater. One part is made of a sheet of metal painted black. Black surfaces become hotter in the sun than surfaces

　　painted any other color.

　　這種太陽能熱水器分為2個(gè)部分。一部分是由涂成黑色的金屬板制成。黑色表面比其它任何顏色的表面都更容易吸熱。

　　This black metal plate is called a collector. The collector is placed in contact with the water.

　　這個(gè)黑色金屬板被稱為集熱器。集熱器與水直接接觸。

　　There are several kinds of metal sheets that can be used for the collector. Corrugated metal will work very well. Corrugated sheets are often used as roofs

　　on housing.

　　有幾種金屬板可用于制造集熱器，波紋金屬效果就很好。波紋金屬板常用作房屋屋頂。

　　Once the water is heated, it is kept hot with insulation material. This allows the water to stay warm for a long time.

　　水一旦被加熱，就通過保溫材料保溫。這使得水可以長時(shí)間保持一定溫度。

　　The second part of the solar water heater holds the water for the system. This storage tank can be a container that holds about one hundred liters. Two

　　rubber pipes are attached to the water storage tank. One pipe lets water flow into the system. The other lets water flow out.

　　太陽能熱水器的另一部分為儲(chǔ)水系統(tǒng)。這個(gè)儲(chǔ)水箱是一個(gè)可以容納約100升水的容器。儲(chǔ)水箱上連有2根橡膠管，一根是進(jìn)水管，一根是出水管。

　　When the water heater is working correctly, water will flow from the storage tank to the collector and back again. You can use the hot water at the top of

　　the tank for washing and cleaning. You can change the flow of water so that the temperature is hot or warm as desired.

　　熱水器工作正常時(shí)，水會(huì)從儲(chǔ)水箱流到集熱器，(溫度升高后)再流回儲(chǔ)水箱。你可以使用儲(chǔ)水箱頂部的熱水來清洗。你可以改變水流大小，從而使水溫達(dá)到理想溫度。

　　This solar water heater is easy to build and operate. It will last about two years bore the rubber pipes need to be replaced.

　　這種太陽能熱水器易于建造和操作。橡膠管(因?yàn)槔匣?大約每兩年需要更換一次。

　　There is also something else you will need to make the solar water heater work -- the sun. As you might imagine, the heater will heat water only on sunny

　　days.

　　要使太陽能熱水器工作還需要一個(gè)因素--太陽。正如你想到的，太陽能熱水器只有在晴天才能把水加熱。

　　You can get more information about solar water heaters and other projects from EnterpriseWorks/VITA. This group works internationally to fight poverty. The

　　website is enterpriseworks.org. Choose the link for News & Resources, then click on Publications.

　　你可以從EnterpriseWorks/VITA獲得更多關(guān)于太陽能熱水器和其他項(xiàng)目的資料，該組織在全球致力于消除貧困。他們的網(wǎng)址是enterpriseworks.org。打開網(wǎng)站后選擇News &

　　Resources分類，然后點(diǎn)擊其中的Publications。

　　SAT閱讀考題重點(diǎn)考察考生的美國大學(xué)教材的快速閱讀能力、理解能力及判斷能力。以上就是澳際小編為大家整理的關(guān)于如何制作太陽能熱水器的SAT閱讀素材的詳細(xì)內(nèi)容，希望對(duì)大家有所幫助，澳際小編祝大家都能取得理想的SAT閱讀考試成績!
