>听力文本 Guide：Welcme abard，time travellers! We’ll begin ur tur shrtly. Tday’s tur will take yu back in time 50 years. Fr sme f yu，this tur will take yu back t the days f yur childhd. [Turists exclaim,“Amazing!” “Ww!” “I can’t wait t see my great grandpa!” befre quietening dwn.] Guide： Befre we start ur tur，I have t explain the rules f time travel. Please listen carefully. Number 1，dn’t talk t anybdy. Turist 1：Why nt? I’m ging t tell my 8-year-ld self t buy shares in cmpanies that are prfitable tday. That way，when I get back t the present，I’ll be rich! Guide： I’m afraid yu cannt d that! If yu d that，yu’ll change yur life path. Maybe yu will grw up t be a rich persn. But that rich persn will be a new persn，nt the persn yu are tday. That persn，the present “yu” will disappear frever. That’s what we call a paradx. Turist 1：S，what yu’re saying is that learning abut the future might change the way I am frever?

In fact，that’s what I was ging t say next—yu must never give anything frm ur time t smene in the past. Turist 2：What abut if I just leave it lying arund fr my father t find? That’s OK，isn’t it? Guide：N，that’s nt allwed，either! Turist 2：Are yu serius? Guide： I certainly am! That is exactly the same as giving it yurself. I wuld strngly advise against interacting with anyne. Turist 2：Let me get this straight. Yu mean that we can’t talk t anyne，can’t break anything，r leave anything in the past? Guide：That’s right. Turist 2：OK，gt it.
