Healthy eating 一、閱讀理解。 (2018廣西重點(diǎn)高中模擬)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 study’s 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 frequency—or RF—radiation is a type known as nonionizing(非電離的). 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 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 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. 【解題導(dǎo)語】　本文是一篇說明文。人們喜歡用手機(jī)，90%的美國人都有手機(jī)。那么，過度使用手機(jī)是否會有患癌的風(fēng)險呢？一項新的研究給出了一些線索。 1．Which of the following can replace the underlined word “augments”？ A．figures out B．puts out C．refers to D．a(chǎn)dds to D　解析：詞義猜測題。畫線詞前面提到過度使用手機(jī)是否有患癌的風(fēng)險這一問題多年來引發(fā)的爭議不斷，再根據(jù)畫線詞后的“concerns”和“Its data linked longterm, intense exposure to radiation from cellphones with an increased risk of cancer in the heart or brain.”可知，現(xiàn)在一項在老鼠身上進(jìn)行的新研究增加了那些憂慮。故畫線詞與adds to意義相近。 2．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 makes a breakthrough in cancer research. B　解析：推理判斷題。根據(jù)第二段最后一句可知，這項研究會促使科學(xué)家去查明手機(jī)輻射可能是怎樣致癌的，也就是說它為科學(xué)家提供了一個新的研究方向。 3．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 nonionizing radiation. C　解析：段落大意題。根據(jù)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，本段主要講的是手機(jī)輻射的特點(diǎn)，它是非電離的，其危害性遠(yuǎn)低于電離輻射。 4．What might be the theme of NTP scientists’ further research? A．Why cellphone use causes cancer. 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：推理判斷題。根據(jù)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的科學(xué)家進(jìn)一步研究的主題可能是手機(jī)使用是否真的會導(dǎo)致癌癥。 二、單句語法填空 1．(2017天津高考)My room is a mess, but I ________ clean it before I go out tonight. I can do it in the morning. 答案：neednt　由“I can do it in the morning”可知，“我”今晚沒必要打掃，應(yīng)用Sb. neednt do sth. 句式。 2．(2017天津高考)I was watching the clock all through the meeting, as I had a train________ (catch)． 答案：to catch　結(jié)合句意可知，此處表示將要發(fā)生的動作，故用動詞不定式作定語。 3．There is a limit ________ the amount of pain we can bear. 答案：to　There is a limit to ... “……是有限度的”。 4．The beautiful lady sat a little straighter and tried to look ________ (slim) and younger. 答案：slimmer　由“and younger”可知，應(yīng)用比較級slimmer “更苗條”。 5．Nowadays more and more people have e to realize the importance of a ________ (balance) diet to their health. 答案：balanced　a balanced diet “均衡飲食”。 6．Children are always curious ________ everything they see and hear. 答案：about　be curious about “對……感到好奇”。 7．Being a good teacher, you should know your students ________ (strong) and weaknesses. 答案：strengths　strengths and weaknesses “強(qiáng)項和弱項”。 8．Lowine residents cant afford ________ (consult) a doctor or purchase medicines when they get sick. 答案：to consult　cant afford to consult a doctor “請不起醫(yī)生”。 9．We cant always bine work ________ pleasure. 答案：with　bine A with B “將A與B相結(jié)合”。 10．Johns ________ (weak) lies in his bad temper. 答案：weakness　由設(shè)空前的Johns可知，應(yīng)填名詞形式weakness “缺點(diǎn)，不足”。 三、完形填空。 閱讀下面短文，從短文后各題所給的A、B、C和D四個選項中，選出可能填入空白處的最佳選項。 I worried about my personal image and how I could be remembered during my boyhood.In the fifth grade，there seemed to be only one __1__ —to be cool.In the sixth grade，suddenly，there were two choices：be cool，or be invisible.__2__ ，one day，when a teacher had us fill out a questionnaire with __3__ questions，I found the __4__ option.

You shouldnt let him get away from stealing from the shop. _____________________________________________________ 答案：from→with　get away with “做了壞事不受懲罰”。 5．He should have handed in his paper yesterday, and he forgot about it pletely. _____________________________________________________ 答案：and→but　前后分句之間為轉(zhuǎn)折關(guān)系。 五、短文改錯 Here is a funny story.One day three mouse said proudly to each other that they each could drink more wine，so they decided to have a drinking contest.At last they both felt dizzy.One suggested，“Will anybody go to the wine cellar to fetch another bottle of wine？” The first stood up and down then fell to the ground.The other two laughed and said，“He was drinking and couldnt walk.” The second stood up.He just made several steps and couldnt help thrown up.The third laughed hardly and then it was their turn. He stood up and made one step，two steps...Nothing is wrong.He went straight to the wine cellar but took a bottle of wine.He stood there for while，turned back and said excitedly，“Ha ha，where is the cat now？” 【答案】　 Here is a funny story.One day three said proudly to each other that they each could drink more wine，so they decided to have a drinking contest.At last they felt dizzy.One suggested，“Will anybody go to the wine cellar to fetch another bottle of wine？” The first stood up and then fell to the ground.The other two laughed and said，“He was and couldnt walk.” The second stood up.He just made several steps and couldnt help up.The third laughed and then it was turn.
