3、tly 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.

4、ut yesterday or tomorrow, and just about whatever s right in front of you. However, the thing is, we don t 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
5、every day. Yes, they might be in Santa Monica, a few blocks from my apartment, but what s 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 yesterda
6、y, 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 what s happening now.” Our generation seems
7、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

12、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
13、 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 stu
14、dys findings “ significant” They could lead to studies researching how cellphone radiation might cause cancer, he says. 【 精品教育资源文库 】 Phone signals are relayed between cell towers and cellphones via radio waves.This radio frequency or RF radiation is a type known as nonionizing(非电离的 ). Unlike Xrays,
15、 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
16、 heat the body and cause tissue damage.But it s not yet known what much lower RF levels might do, such as those from cellphone use.Five years ago, the World Health Organization s International Agency for Research on Cancer, or IARC, concluded that cellphone use “ is possibly carcinogenic(致癌的 )” Its
17、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, investigated further. 【解题导语】 本文是一篇说明文。人们喜欢用手机 ， 90%的美国人都有手机。那么 ，过度使用手
18、机是否会有患癌的风险呢？一项新的研究给出了一些线索。 4 Which of the following can replace the underlined word “augments” ？ A figures out B puts out C refers to D adds to D 解析：词义猜测题。画线词前面提到过度使用手机是否有患癌的风险这一问题多年来引发的争议不断 ， 再根据画线词后的 “concerns” 和 “Its data linked longterm, intense exposure to radiation from cellphones with an incr
19、eased risk of cancer in the heart or brain.” 可知 ， 现在一项在老鼠身上进行的新研究增加了那些忧虑。故画线词与 adds to 意义相近。 5 In which aspect does Jonathan Samet think the new study in rats is significant? A It assists him with his teaching. B It indicates a new research direction. C It warns people to mind cellphone safety. D It
20、 makes a breakthrough in cancer research. B 解析：推理判断题。根据第二段最后一句可知 ， 这项研究会促使科学家去查明手机辐射可能是怎样致癌的 ， 也就是说它为科学家提供了一个新的研究方向。 6 What is Paragraph 3 mainly about? A How phone signals are delivered. B How cellphones produce radiation. C Features of radiation from cellphones. D Differences between ionizing and
21、nonionizing radiation. C 解 析： 段落大意题。根据第三段的 “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.” 可知 ， 本段主要讲的是手机辐射的特点 ， 它是非电离的 ， 其危害性远低于电离辐射。 7 What might be the theme
22、of NTP scientists further research? A Why cellphone use causes cancer. 【 精品教育资源文库 】 B Whether cellphone use really causes cancer. C What health effects cellphone use has. D How much exposure to cellphone radiation is safe. B 解析：推理判断题。根据最后一段中的 “It said only that phone use might possibly cause cancer.So scientists at the National Toxicology Program, or NTP, investigated further.” 可知 ， NTP 的科学家进一步研究的主题可能是手机使用是否真的会导致癌症。 II 完形 填空 (2018 辽宁省五校协作体高三上学期联合模拟 )Falling off a boxcar and landing on my head， I lost my sight when I was four years old.
