(2020·新高考Ⅰ卷,阅读理解D)——健康的生活方式、积极的生活 态度Accrding t a recent study in the Jurnal f Cnsumer Research,bth the size and cnsumptin habits f ur eating cmpanins can influence ur fd intake.And cntrary t existing research that says yu shuld avid eating with heavier peple wh rder large prtins(份),it's the beanples with big appetites yu really need t avid.
T test the effect f scial influence n eating habits,the researchers cnducted tw experiments.In the first,95 undergraduate wmen were individually invited int a lab t stensibly(表面上) participate in a study abut mvie viewership.Befre the film began,each wman was asked t help herself t a snack.An actr hired by the researchers grabbed her fd first.In her natural state,the actr weighed 105 punds.But in half the cases she wre a specially designed fat suit which increased her weight t 180 punds.Bth the fat and thin versins f the actr tk a large amunt f fd.The participants fllwed suit,taking mre fd than they nrmally wuld have.Hwever,they tk significantly mre when the actr was thin.
Fr the secnd test,in ne case the thin actr tk tw pieces f candy frm the snack bwls.In the ther case,she tk 30 pieces.The results were similar t the first test:the participants fllwed suit but tk significantly mre candy when the thin actr tk 30 pieces.The tests shw that the scial envirnment is extremely influential when we're making decisins.If this fellw participant is ging t eat mre,s will I.Call it the “I'll have what she's having” effect.Hwever,we'll adjust the influence.If an verweight persn is having a large prtin,I'll hld back a bit because I see the results f his eating habits.But if a thin persn eats a lt,I'll fllw suit.If he can eat much and keep slim,why can't I?
真题再做12.What is the recent study mainly abut?A.Fd safety.B.Mvie demand.D.Eating behavir.
解析:细节理解题。根据第一段第一句可知,这项研究是关于就餐同伴对人们的食物摄取量的影响的。故选D项。
13.What des the underlined wrd “beanples” in paragraph 1 refer t?A.Big eaters.B.Overweight eaters.D.Tall thin persns.
解析:词义猜测题。根据第一段第二句可知,现行研究认为,你应该避免与点大份餐的胖人一同吃饭。但与此相反,这项研究结果显示,你真正应该回避的是大饭量的瘦高个子。最后一段也有提示。故选D项。
14.Why did the researchers hire the actr?A.T see hw she wuld affect the test if the participants culd recgnize find ut what she wuld d in the tw study why she culd keep her weight dwn.
解析:推理判断题。根据第三段内容可推知,研究者们雇用了一位演员,目的在于看她如何影响参与者的胃口。故选A项。
15.On what basis d we “adjust the influence” accrding t the last paragraph?A.Hw hungry we slim we want t we perceive we feel abut the fd.
解析:推理判断题。根据最后一段描述可知,如果一位超重的人吃得多,“我”会减量,因为“我”能看到他饮食习惯的结果;但是如果一位瘦人吃得多,“我”则会跟着多吃。由此可推知,人们饭量的调整基于对吃饭的人的看法。故选C项。
语言能力1.掌握构词知识
2.猜测生僻词词义Accrding t a recent study in the Jurnal f Cnsumer Research,bth the size and cnsumptin habits f ur eating cmpanins can influence ur fd intake.

s d the Chinese
5.破解复杂句式And cntrary t existing research that says yu shuld avid eating with heavier peple wh rder large prtins,it's the beanples with big appetites yu really need t avid.分析:这是一个复合句,短语cntrary t后有that引导的　　　　从句修饰existing research;yu really need t avid又是一个　　　　从句,with big appetites是介词短语做　　语,用来修饰　　　　　　　　　 。 译文:
the beanples
和现行研究认为的 “你应该避免和肥胖且点大份餐的人在一起吃饭” 相反,你真正需要避免(一同吃饭)的应该是身材苗条但是吃得多的人。
