B.Healthcondition.C.Physicalactivity. D.Eatingspeed.【解析】選D。細節(jié)理解題。根據(jù)第二段中的“splittingthemintothreecategoriesbasedonhowquicklytheyate:slow,normal,andfast”可知,按照參與者吃飯的速度,研究者將他們分為吃得慢、正常、快三個類別。2.Whichmaybetheresultofthestudy?A.Fasteatersare4timesmorelikelytohavemetabolicsyndrome.B.Normalandsloweatersdon’thavemetabolicillness.C.89%offasteatershavehigherbloodpressure.D.Sloweatersarehealthierthanfasteaters.【解析】選D。推理判斷題。根據(jù)第三段中的“Fasteatersalsosawmoreweightgain,largerwaistlines,andhigherbloodsugarlevelsthansloweaters.”可知,比起吃得慢的人,吃得快的人體重增加更多、腰圍更大、血糖水平也更高,反向推知,吃得慢的人比吃得快的人更健康。3.Whatdoestheunderlinedword“gobbling”inParagraph4mean?A.Tastingslowly. B.Digestingquickly.C.Eatinggreedily. D.Cookingcarefully.【解析】選C。詞義猜測題。根據(jù)第四段中的“whenpeopleeatfasttheyaremorelikelytoovereat”可知,吃得快可能會讓人吃得過多。所以這個詞的意思應(yīng)是“狼吞虎咽地吃”,故選C項。4.Whatdoesthelastparagraphtellus?A.Theimportanceofeatingspeed.B.Theadvantageofeatingslowly.C.TheresultofaChinesestudy.D.Fasteatingandovereating.【解析】選B。段落大意題。根據(jù)文章最后一段的中心句“Previousresearchbacksuptheweightbenefitsofsloweating,too.”及下文內(nèi)容可知,本段主要講吃得慢的好處。Ⅱ.完形填空
