【能力提升】Ⅰ.閱讀
1.A推理判斷題。根據(jù)第二段中的“Itproducesadeafeningsoundsopainfulthatittemporarilydisablesaperson.ThenoisefromtheLRADisdirectedlikearayoflightandtravelsonlyintotheearsofthatperson,butitisnotdeadly.”可知它發(fā)出震耳欲聾的聲音,這種聲音令人如此痛苦以至于它會使人暫時喪失能力。LRAD發(fā)出的噪音像光線一樣被引導(dǎo),只進(jìn)入那個人的耳朵,但不會致命。由此可推知,LRAD會導(dǎo)致暫時性聽力損失。故選A。
2.D細(xì)節(jié)理解題。根據(jù)第三段中的“Well,itfunctionsbyanalyzingthewavesoftheincomingsoundandcreatingasecondsetofoutgoingwaves.Thetwosetsofwavescanceleachotherout.Simplyturnthemachineon,pointitatthetarget,andyourpeaceandquietcomesback.”可知,它的功能是通過分析傳入聲音的波,并產(chǎn)生第二組傳出的波。這兩組波會相互抵消。只要打開機(jī)器對準(zhǔn)目標(biāo),你的寧靜就會回來。由此可知,靜音機(jī)是一種專門設(shè)計用來阻止有害聲音影響你的設(shè)備。故選D。
3.D細(xì)節(jié)理解題。根據(jù)最后一段中的“Aspotlightlightsuponlyonesectionofastage;similarly,a“spotsound”createsacircleofsoundinonetargetedarea.”可知,聚光燈只能照亮舞臺的一個部分;類似地,一個“spotsound”在一個目標(biāo)區(qū)域創(chuàng)建一個聲音圈。由此可知,spotsounds和聚光燈的共同特性是它們可以被定向到一個特定的區(qū)域,故選D。
4.C細(xì)節(jié)理解題。根據(jù)最后一段中的“Aspotlightlightsuponlyonesectionofastage;similarly,‘a(chǎn)spotsound’createsacircleofsoundinonetargetedarea.Thiscanbeusefulforbusinessessuchasrestaurantsandstoresbecauseitoffersanewwaytoattractcustomers.Restaurantscanofferachoiceofmusicalongwiththevariousfoodchoicesonthemenu,allowingcustomersmorecontrolovertheatmosphereinwhichtheyaredining.”可知,聚光燈只能照亮舞臺的一個部分;類似地,一個“spotsound”在一個目標(biāo)區(qū)域創(chuàng)建一個聲音圈。這對餐館和商店等企業(yè)很有用,因?yàn)樗峁┝艘环N吸引顧客的新方式。餐廳可以提供音樂選擇與菜單上的各種食物選擇,讓顧客更多地控制氣氛,在他們用餐時。由此可知,定向音響可以用于不同的商業(yè)音樂選擇。故選C。
5.B主旨大意題。根據(jù)第一段中的“Inthepast,soundengineersworkedinthebackroomsofrecordingstudios,butmanyoftoday'ssoundprofessionalsaresharingtheirknowledgeandexperiencewithprofessionalsinotherfieldstocreatenewproductsbasedonthephenomenonwecallsound.”可知,在過去,音響工程師在錄音室的后室工作,但今天的許多音響專業(yè)人士正在與其他領(lǐng)域的專業(yè)人士分享他們的知識和經(jīng)驗(yàn),以我們所謂的聲音現(xiàn)象為基礎(chǔ)創(chuàng)造新產(chǎn)品。結(jié)合下文具體內(nèi)容可知,本文著重論述了聲音技術(shù)領(lǐng)域的發(fā)明創(chuàng)造。故選B。
Ⅱ.七選五
【語篇解讀】本文是篇說明文,向讀者介紹了三種滿足不同閱讀目的的閱讀方式。
1.C空后的“thethreereadingstyles”和C項中的“threeimportantreadingstyles”相對應(yīng),故答案為C項。
2.B本段主要講thestudyreadingstyle這種閱讀方式,故選B項。
3.E根據(jù)語境可知,本空是對theskimmingstyle這一閱讀方式的進(jìn)一步說明,故選E項。
4.FF選項中的“Theinformationtobelocated”與空前一句相對應(yīng),故選F項。
5.D根據(jù)空前的敘述可知,本句應(yīng)為選擇合適的閱讀方式,故答案為D項。
Ⅲ.完形填空
1.A考查名詞。degree在此處意為“學(xué)位”。由空前句中的whodidn'tfinishschoollikemanyofhercontemporarygirls可知的母親沒有完成學(xué)業(yè),所以的母親沒有獲得學(xué)位。故A項正確。
2.D考查形容詞。根據(jù)空后內(nèi)容“Mama,whydoIhavetolearnthese__3__words?”和本段的母親對他的教育可知,當(dāng)時一遍遍地記外語單詞,感覺很煩,所以D項正確。
3.C考查形容詞。由下文forthispenandthenewlanguagewillbeyourcompasstosailaroundtheworld可知的母親讓她學(xué)習(xí)外國詞匯,故選C項。
4.A考查動詞。由空后的母親的鼓勵的話可以判斷A項正確。
5.A考查連詞。本句中的Ihadtogetupastheearlysunroseandthenran8.8milesbarefoottoschool表明每天要早早起床跑8.8英里才能到學(xué)校,故可知雖然搬去了離學(xué)校較近的地方
