就……”;aswellas“除……之外";asmuchas“和……一樣多”;aspossibleas“盡可能的”。本句意為:人類一離開大氣層就會(huì)接觸到射線。故選A項(xiàng)。10.Bbeexposedto“暴露于”,show“展示";face“面對(duì)”;cover“覆蓋,涉及,包含”。根據(jù)句意應(yīng)選B項(xiàng)。11.A本句前半句的意思是:人們一離開大氣層就會(huì)接觸射線;后半句意思是:他們的太空服和太空船會(huì)阻止射線造成的損害。前后應(yīng)該是轉(zhuǎn)折關(guān)系,故用but.12.Ddo+動(dòng)詞原形的結(jié)構(gòu)表示強(qiáng)調(diào)謂語(yǔ)動(dòng)詞。13.C由radiation和explorers可推測(cè),應(yīng)選space(太空)。本句意為:射線是探險(xiǎn)者在太空遇見的已知的最大危險(xiǎn)。14.Bunit“單位、單元”;element“元素”;part“部分”;piece“碎片"。本句意為:射線的多少可以以雷目這個(gè)測(cè)量單位測(cè)量。15.Areceive表示客觀收到;accept表示主觀接受。我們受到的輻射并非主觀接受。16.Dconventional“傳統(tǒng)的”;common“共同的,普通的”;general“一般的,總體的”;normal“正常的”。本句意為:我們每年接受的正常輻射量大約為2毫雷目。故選normal。17.Dshift“移動(dòng)”;convert“轉(zhuǎn)換”;modify“修改”;vary“變化"。本句句意:所處地點(diǎn)不同,所受輻射量也不一樣……,故選varies。18.C本句應(yīng)填入引導(dǎo)賓語(yǔ)從句的代詞,而從句不缺少主語(yǔ)和賓語(yǔ),因而不選擇what和which,加之主句是陳述語(yǔ)氣,故選擇that。19.Aputupwith“忍受”,固定搭配。keepupwith和catchupwith意為“跟上”,comeupwith意為“提出”。20.B與前面的more相對(duì)應(yīng)。Ⅳ。閱讀表達(dá)Ifthesunhasenoughpowertowarmandlightthewholeearth,itmusthaveenoughpowertodootherthings,too.Canweusethesun’sabundantenergytosupplyelectricity,oratleasttoperformthefunctionswhichelectricityorothertypesofpowerusuallyperform?Theanswerisyes.Forexample,peoplehaveformanyyearsbeenusingthereflectedheatofthesuntocook.Solarcookershavebeenbuiltwithseveralcurved(彎曲)mirrorsreflectingthesunandfocusingitsheatonthecookingcomponent.This_equipment_can_be_used_just_like_a_gas_or_electric_stove;it_is_more_expensive_to_make_but_it_does_not_need_any_fuel,and_so_costsnothing_to_use。Anotherpossibilityofusingsolarenergyisinhouseheating。Theformofenergyweusemostiselectricity,andeverydaymoreisneeded.Butelectricityhastobemade,too,andtomakeit______arerequired-oil,gasandnowadaysevenuranium(鈾).Thequestionwhichworrieseveryonetodayis:howlongwillthesefuelslast?Nobodyknowsitforsure,butmostexpertsthinkitwillsoonbedifficulttoobtainsufficientelectricityfromthesesources.Itispossiblethatthesuncanmakeacontributionhere,too。Solarpowerhasalreadybeenusedtoproduceterrificheat.InSouthernFranceasolarfurnace(hugestove)hasbeenbuilt,wheretemperaturesreachmorethan3000℃。Thisfurnaceisonlyusedforexperimentsatpresent,butcouldbeusedtoproducestreamforapowerstation.1.Whatisthemainideaofthepassage?(Pleaseanswerwithin10words.)__________________________________________________________________________________________________________________________
