Unit 3 Travel journal 阅读理解AAbout six months ago, I was working in a job where I sat at a computer in an office for 50 hours or so each week. My best friend, Dusty，also sat in an office at a computer all day. We often talked about what a waste it seemed to be, spending our time inside in front of a computer all day long. I ended up leaving my job, and so did Dusty. Neither one of us are sitting in an office all day. Last week, Dusty came to my home and declared，“Im going to travel.” Of course, traveling is exciting. Its getting to experience new things, getting to be a slightly different version of ourselves, but I think the point is more about the mindset(心态) that it allows for than the actual reality that comes with it. Waking up every day with a sense of excitement for the unknown. Approaching each interaction during the day with a sense of wonder. Not thinking about yesterday or tomorrow, and just about whatevers right in front of you.However, the thing is, we dont need to be in transit to be able to approach our days this way. It is possible for me to be living my normal life and be excited for the unknown of the day. I meet new people and do new things every day. Yes, they might be in Santa Monica, a few blocks from my apartment, but whats the difference between a new person here and a new person in Australia?I read an Alan Watts quote recently, and it goes as follows：“If I ask you what you did, saw, heard, smelled, touched and tasted yesterday, I am likely to get nothing more than the thin, sketchy outline of the few things that you noticed, and of those only what you thought worth remembering. But suppose you could answer，It would take me forever to tell you, and I am much too interested in whats happening now.”Our generation seems to be eager to expand our horizons(视野). But I agree with Alan Watts. There is a lot of opportunity for horizonexpansion wherever we happen to be. I think Ill wake up tomorrow, walk down the street, and put on my adventurers cap.【解题导语】旅行之所以吸引人是因为它可以让人们探索未知，但是并不一定非要去旅行才可以达到这个目的。正如阿兰沃茨建议的，我们应该关注当下，因为我们看似平淡的日常生活同样可以很精彩。1According to the text, the author quit his job mainly because Ait didnt pay very wellBDusty advised him to do soChe wanted to spend some time travelingDhe didnt want to stay inside all day longD解析：细节理解题。根据第一段中的“. what a waste it seemed to be, spending our time inside in front of a computer all day long. I ended up leaving my job. in an office all day.”可知，作者和朋友都不喜欢每天待在室内，坐在电脑前，所以他们辞掉了工作。故选D项。2The underlined words “in transit” in the third paragraph probably mean “ ”Amoving aroundBworking hardCfilled with curiosityDfull of enthusiasmA解析：词义猜测题。第二段内容讲述旅游的魅力所在，第三段首句使用单词 However(然而)表转折，表明本段表述的内容与第二段内容不同，即我们不需要到处逛，也可以使我们的生活一样精彩，moving around 意为“走来走去”符合句意，故选A项。3Whats the best title for the text?AAn Exciting but Normal LifeBAdventures in Our Own BackyardCGo to Travel and Expand Your HorizonDGet Outside and Explore for the UnknownB解析：标题归纳题。文章第三段表明了作者的观点，我们不一定非要去旅行才能探索未知，发现新的自我，下文引用了阿兰沃茨的话，表明我们应该活在当下，因为我们看似平淡的日常生活同样可以很精彩。故选 B 项。B(2018广西重点高中模拟)People love cellphones, which is why nine in ten Americans own one.But does heavy use of cellphones pose a risk of cancer? This question has caused controversy for many years. A new study in rats now augments those concerns.Its data linked longterm, intense exposure to radiation from cellphones with an increased risk of cancer in the heart or brain.The results have yet to be confirmed, the authors note.Indeed, although the rat study found a link between cellphone radiation and cancer, it offers no clues to why such a link might exist, notes Jonathan Samet.He teaches preventative medicine and directs the Institute for Global Health at the University of Southern California in Los Angeles.Still, he calls the new studys findings “significant”They could lead to studies researching how cellphone radiation might cause cancer, he says.Phone signals are relayed between cell towers and cellphones via radio waves.This radio frequencyor RFradiation is a type known as nonionizing(非电离的). Unlike Xrays, nonionizing radiation does not deposit enough energy into cells to release electrons from atoms or molecules, producing ions.So it tends to be far less harmful than ionizing radiation, such as Xrays.But that does not mean radio waves might not cause harm.In very large doses(量) this radiation will heat the body and cause tissue damage.But its not yet known what much lower RF levels might do, such as those from cellphone use.Five years ago, the World Health Organizations International Agency for Research on Cancer, or IARC, concluded that cellphone use “is possibly carcinogenic(致癌的)”Its conclusion was based on what little research data was available at that time.But notice that IARC was not certain.It said only that phone use might “possibly” cause cancer.So scientists at the National Toxicology Program, or NTP, i
