空后列舉了造成睡眠不好的幾個(gè)方面，由此可見此段主要介紹導(dǎo)致睡眠不好的主要表現(xiàn)形式，所以B項(xiàng)的Goingtobedtoo睡覺太)也之一，所以選B項(xiàng)答與解析：E項(xiàng)的contributesto與句中“l(fā)eadsto是相同的表達(dá)同一更好體現(xiàn)二之間的連貫，所以選項(xiàng)Ⅲ語填（江西五校第一次聯(lián)考TheWorldhasanappealscientists,drugmanufacturersandwantswork__1__(develop)drugsfight12bacteria.bacteriatoantibiotic(抗素sounusuallythatthe12bacteriahavebeengivenaspecialname“superbug．TheUnitedNationsagency12superbugsthreattohuman__4__(healthy).Itsaidthey__5__abilityturntreatablekillers.TheWHOsayssuperbugsalsoalonggenetic__6__helpsbacteriabecomeresistanttodrugtreatment.riePauleKienyistheAssistantDirectorGeneralatWHO.Shesaid,“Antibioticresistanceisgrowingandwearerunningout__7__treatmentoptions.”urgedgovernmentstogivedrugcompaniesreasonstodevelopnewtreatments.leav
