2.細(xì)節(jié)理解題。根據(jù)文章第四段"Thedraftalsosaysthatanimalabuseandabandoninganimalswillbeconsideredcrimesunderthecriminallaw."可知B、C兩項(xiàng)不被接受,最后一段中"Itsaysthatpeopleshouldnotforceanimalstodosomethingdangerous,likejumpingthrougharingoffire."可知D項(xiàng)也不能被接受。

3.推理判斷題。從文章的后三段來(lái)看,人們對(duì)于該草案所持的態(tài)度各不相同,故答案應(yīng)為D。

4.推理判斷題。根據(jù)文章最后一段可知,該草案禁止動(dòng)物進(jìn)行危險(xiǎn)的表演,所以如果草案得以實(shí)施,可能就不會(huì)再有動(dòng)物表演雜技了,C項(xiàng)正確。BHowdoyoukillyourtimewhenyougotowork?Mostofusstareatourcellphones,andrefusetomakeeyecontactwithothers.Wejustread,chatwithothersonlineorplaygamesonline.Ormaybewe’reusingthetimebetweenstopstodoourmakeup,catchuponemails,orreadafewchaptersofabook.However,DinaAlfasitakesaverydifferentapproach.EachdayshehastotravelhoursonbusesandtrainstogettoherengineeringjobatahospitalinIsrael.Ratherthanlookathercellphoneinsilence,sheusesoneveryspecialwaytohaveconnectionwithstrangers.Itisportraitsofthepeopleshemeetsonpublictransporteverydaythatsheistaking.Thephotographscatchthosequietandpersonalmomentsofpeoplereadyingthemselvesforthedayahead.Somepeoplelean(倚靠)theirheadagainstthewindowandgotosleep,somestareintospaceandhaveadaydream,andotherssitquietlytoreadtheirdocumentsorbooks.Eachpicturecatchesonetinymomentinpeople’slives,ripewithpotentialforyourimagination.Itiswonderfulforhertolookatsomeone’scommute(上下班)andmakeupanentirestoryabouttherestoftheirdailyexistence,fromthefathertravellingwithababytothewomanwelcomingachange.“Whatinspiresmeverymucharethelittlemomentsthathappeneveryday,”DinatoldMyModernMet.“Myworkistotellstoriesthroughasingleportrait,anditprovesthatallyouneedisjusttolookaroundandfindthosemagicmoments.”1.Whatwillmostpeopledowhengoingtowork?A.Enjoyreadingabookloudly.B.Makeeyecontactwithothers.C.Haveface-to-facetalkswithothers.D.Concentrateontheirmobilephones.2.WhatmakesDinadifferentfromothers?AStaringintothespaceandhavingadaydream.B.Leaningagainstthewindowandrelaxingherself.C.Usinghermobilephonetoappreciatepicturesshedraws.D.Drawingpeoplewhiletravellingonbusesandtrainstowork.3.WhichwordcanbestdescribeDinaAlfasi?A.Cool.

Chooseatimewhenyounormallyfeeltiredsothatyoucanfallasleepeasily.七選五答案：EGADF

解析：①根據(jù)上文中的"Whatworksforsomemightnotworkaswellforothers"可知,對(duì)一些人有效的方法不一定對(duì)其他人也同樣有效,所以應(yīng)該找到最適合自己的睡眠習(xí)慣。故選E。②根據(jù)上文中的"Setaregularbedtime.Gotobedatthesametimeeverynight"可知,本段主要講要制訂一個(gè)有規(guī)律的睡眠時(shí)間。因此接下來(lái)應(yīng)說(shuō)選擇一個(gè)自己通常感到疲倦的時(shí)刻,這樣你能夠容易入睡。故選G。③根據(jù)下文中的"Ifyougetenoughsleep,youshouldwakeupontimenaturallywithoutanalarm"可知,如果你得到了足夠的睡眠,你應(yīng)該不需要鬧鐘就可以按時(shí)自然醒來(lái)。故本段主旨句應(yīng)該是說(shuō)每天在相同的時(shí)間醒來(lái)。故選A。本段中的"keepyourregularwake-uptime"也是信息提示。④根據(jù)上文中的"Whiletakinganapcanbeagreatwaytorechargeone'sbatteries,especiallyfortheelderly,itcanmakeinsomnia(失眠)worse"可知,小睡雖然是一個(gè)養(yǎng)精蓄銳的好方式,尤其對(duì)老年人來(lái)說(shuō),但是它能使失眠更嚴(yán)重。接下來(lái)應(yīng)該說(shuō),如果失眠對(duì)你來(lái)說(shuō)是一個(gè)問題的話,那么應(yīng)該考慮放棄小睡了。故選D。⑤根據(jù)上文中的"Whatshouldyoudowhenyouaregettingsleepybeforeyourbedtime?"可知,上句講到"在你睡覺之前,如果感到困倦的話,應(yīng)該怎么做?"那么接下來(lái)應(yīng)該說(shuō)的是減少倦意的方式,故選F。三、完形填空
