(2017·赣州市高三年级适应性考试)
I grew up with a fat dad—450 pounds at his heaviest.Every week he would try a new diet，and my family ended up eating whatever strange food he was trying at that moment.
After my thirdgrade year，my dad landed a lifechanging job in Manhattan.My mom，my little sister and I had to move away from our hometown，Chicago，and leave my grandmother and her beautiful food behind.
Leaving my grandmother was far more frightening than the move to New York City.There would be no more special weekends at my grandmother’s house，the only place I can remember feeling happy，safe and nourished (有营养的)．It was what I desired.In this new city，I felt extremely alone and lost，and I missed my grandmother terribly.
My grandmother knew just how I felt—And she knew the cure.Every week，she would send me a card with a $20 bill，a recipe and a list of what to buy at the market.It kept us bonded，and her recipes filled my body and soul.
Over the years，I have grown to better understand my father’s struggles with weight and the toll (代价) it took on him and those who love him.I have come to realize he was driven not by vanity (自负) or selfishness as much as by a deep pain.And in spite of growing up in such an unhealthy eating environment (or perhaps because of it)，as an adult I found a passion and a career as a nutrition consultant.
Today，my father weighs 220 pounds and is a vegan (素食者)．How he got there is a story I hope to share in the coming weeks.More importantly，food is no longer a barrier that keeps us apart，but a bridge that keep us connected.There is nothing my dad enjoys more than talking with me about dietary theories and his weightloss victories.And now I am the one regularly sending recipe cards to my father’s house，just as my grandmother did for me.
1．What kind of person was actually the author’s father?
A．He was a man of vanity and selfishness.
B．He didn’t like to eat with his family.
C．He was more painful than selfish.
D．He forced his family to eat what he liked.
2．The author desired to go to his grandmother’s________.
A．to see his father B．for tasty food
C．for pocket money
D．to avoid his family
3．The underlined word “cure” in Paragraph 4 is the nearest in meaning to “________”．
A．solution B．concern
C．operation D．situation
4．The author became a nutrition consultant mainly because________.
A．his father often talked with him about dietary theories
B．he was determined to change his own daily habits
C．he wanted to study the recipes his grandmother had given him
D．his childhood experiences gave him too deep an impression
5．What can we learn about the author from the last paragraph?
A．He often quarreled with his father about food
B．His father will tell him his story in the following weeks
C．The most he talks about with his father is nourishment
D．He often sends recipe cards to his grandmother in return
B
(2017·山东济宁模拟)
An alcohol breath test (ABT) is often used by the police to find out whether a person is drunk while driving.In the United States，the legal blood alcohol limit is 0.08% for people aged 21 years or older，while people under 21 are not allowed to drive a car with any level of alcohol in their body.A “positive” test result，a result over the legal limit，allows the police to arrest the driver.However，many people who tested positive on the test have claimed that they only drank a “nonalcoholic” energy drink.Can one of these energy drinks really cause someone to test positive on an ABT？Researchers in Missouri set up an experiment to find out.
First，the amount of alcohol in 27 different popular energy drinks was measured.All but one had an alcohol level greater than 0.005%.In nine of the 27 drinks，the alcohol level was at least 0.096%.The scientists then investigated the possibility that these small levels of alcohol could be discovered by an ABT.They asked test subjects to drink a full can or bottle of an energy drink and then gave each subject an ABT one minute and 15 minutes after the drink was finished.
For 11 of the 27 energy drinks，the ABT did find the presence of alcohol if the test was given within one minute after the drink was taken.However，alcohol could not be discovered for any of the drinks if the test was given 15 minutes after the drink was consumed.This shows that when the test is taken plays an important role in the test result.The sooner the test is conducted after the consumption of these drinks，the more likely a positive alcohol reading will be obtained.
6．What is the legal alcohol level for a 20yearold driver in the US?
A．0.000%.B．0.005%.
C．0.080%.D．0.096%.
7．What is the purpose of the Missouri experiment?
A．To introduce a new method of calculating blood alcohol levels.
B．To discover the relation between energy drinks and ABT test results.
C．To warn people of the dangers of drinking energy drinks.
D．To change the current legal alcohol limit for drivers in the United States.
8．The underlined word “subjects” in Paragraph 2 refers to________.
A．the things that are being discussed
B．areas of knowledge studied in school
C．the participants in an experiment
D．the people who belong to a country
9．Which of the following affects the ABT test result most for energy drink consumers?
A．The age of the person who takes the test.
B．The place where the test is given.
C．The equipment that the test uses.
D．The time when the test is taken.
10．Which of the following is true according to the passage?
A．A driver whose blood alcohol level is found to be 0.1% will be arrested.
B．No energy drinks really cause anyone to test positive on an ABT.
C．Few popular energy drinks contain alcohol in them.
D．Those taking an ABT 15 minutes after drinking alcohol cannot be found out.
课时作业(十二)
Ⅰ.单项填空
1．解析： 考查交际用语。句意为：——实在是太感谢你那天送我的生日礼物了。——不用客气。That’s right没错；Don’t mention it不客气；With pleasure(客气地接受或同意)当然了，很愿意，Nice work干得好，故答案为B。
答案： B
2．解析： gain a better understanding of...表示“获得对……更好的理解”，故第一空用不定冠词a；society表示“社会”，其前不用冠词。
答案： C
3．解析： 考查名词性从句。此句中referred to后缺少宾语，因此应用what引导该主语从句。
答案： B
4．解析： 考查情态动词。句意为：——这封信是你母亲寄来的吧？——是的。但这封信不可能是她自己写的，因为她一个字也不认识。根据because引导的原因状语从句可知，此处应用can’t have done表示对过去发生的事很有把握的否定推测。
答案： B
5．解析： 句意为：在选专业之前你最好考虑你的优缺点。strength强项，优势，符合句意。
答案： A
6．解析： 句意为：——你搬进新家了吗？——没呢。我没时间置办家具。get sth.done表示“使(某事)发生，使完成(某事)”，故选furnished。
答案： B
7．解析： 考查动词短语。句意为：我小时候特别害怕上学，但很快就克服了。get over表示“克服”，符合句意。前三项分别表示“离开”“被理解，把……讲清楚”“进展”，都与句意不符。
答案： D
8．解析： 考查名词辨析。句意为：药品通常应该放在家里孩子们够不着的地方。keep sth.out of the reach of sb.把某物放在某人够不着的地方。
答案： B
9．解析： 考查定语从句。句意为：我认为会受到严厉惩罚的那位官员反而加薪了。分析句子结构可知“________I thought would be seriously punished”为定语从句，先行词为The official，在从句中作主语，故用who。
答案： C
10．解析： 考查固定用法。句意为：她不能帮忙打扫房间，因为她正在厨房忙着做蛋糕。help (to) do sth.帮忙做某事，是固定短语，符合句意。注意：此处不是can’t help doing sth.“禁不住做某事”这个固定词组。
答案： A
11．解析： 考查时态。句意为：我以为老师会就我们的考试结果说些什么，但是他提都没提。根据句意可知，此处表示的是发生在过去的一件事情，因此用一般过去时。
答案： D
12．解析： 考查交际用语。句意为：——这个周末你打算做什么？——看情况，如果时间允许，我可能会和朋友一起去上海。根据答语中的“ I may go to Shanghai”可知，答话人只是有去上海的可能，也有可能不去，所以不太肯定，故选D。
答案： D
13．解析： 考查短语动词含义的辨析。cut down削减、缩短、砍倒；put down放下、写下、批评，奚落，贬损；turn down关小，调低、拒绝；settle down安顿下来。与费用(expenses)有关时，常用削减(cut down)费用。句意为：当价格飞涨时，许多人做出了削减费用的举措。
答案： A
14．解析： 句意为：一般来说，几乎所有的孩子都对周围所有一切是怎么发生的感到好奇。curious好奇的；careful细心的；anxious着急的，担忧的；excited激动的。
答案： A
15．解析： 句意为：积极的态度、乐意争取适当的外援和锻炼稳定的学习习惯合并起来定将决定你的学习成绩。本题考查动词辨析。根据句意，可首先排除conclude(结束，做结论)和conduct(引导，管理，指挥)。combine合并；connect联合，联系。本句中强调将attitude，willingness及exercising合并(as a whole)，并非简单的联系，故答案为B项。
答案： B
Ⅱ.阅读理解
语篇解读 本文是一篇记叙文。作者小时候，爸爸很胖，每周都需要尝试一种新的食物来减肥，全家人都不得不与爸爸一起“试吃”，为此作者对爸爸意见很大。后来随着年龄的增长，作者对父亲也有了更深的理解，在选择职业时也选了营养师这份工作。
1．解析：
推理判断题。根据第五段第一、二句“Over the years...I have come to realize...as much as by a deep pain.”可知，这些年来，作者逐渐理解了父亲，意识到他苦苦地与自己的体重作斗争，不是虚荣和自私，而是对于自己的体重感到深深的痛苦。由此可知，C项内容与题意相符。
答案： C
2．解析： 细节理解题。根据第二、三段内容可知，作者和家人一起搬到了曼哈顿，离开了祖母还有她做的精致美食，以致作者非常想念祖母，特别渴望去她的家里品尝美味佳肴。
答案： B
3．解析： 词义猜测题。根据第四段画线词前后内容可知，作者的祖母知道作者心中的想法，每周会给作者寄20美元，一个食谱还有一个购物单。结合选项可推知，画线词所在句子意思是作者的祖母知道解决的办法。因此画线词的意思与选项中solution的词义最为接近。
答案： A
4．解析： 细节理解题。根据第五段最后一句“And in spite of growing up in such an unhealthy
eating
environment...I
found
a
passion
and
a
career
as
a nutrition consultant.”可知，尽管在一个如此不健康的饮食环境中成长(也许正是因为这一点)，作者长大后成为了一个营养咨询师。由此可知，作者童年的经历给他留下了很深的印象，因此，作者后来成为一名营养咨询师。
答案： D
5．解析： 细节理解题。根据文章最后一段第四句“There is nothing my dad enjoys more than talking with me about dietary theories and his weightloss victories”可知，作者和父亲谈论最多的应该是食品方面的内容。
答案： C

8．解析： 词义猜测题。根据语境可知，文章中画线句子的意思是：他们要求参加测试的实验者喝下一满听或一瓶能量饮料，然后在一分钟和十五分钟后对其ABT进行测试。由此可推知，此处的subject是指参与实验的人。
答案： C
9．解析： 细节理解题。根据文章最后一段中的“the test was given within one minute...15 minutes...This shows that when the test is taken plays an important role in the test result.The sooner the test is conducted after the consumption of these drinks，the more likely a positive alcohol reading will be obtained.”可知，在饮用功能性饮料多久之后进行测试会影响测试效果。
答案： D
10．解析： 推理判断题。根据文章第一段可知，合法的血液酒精浓度最高值应该是0.08%，如果超过这个浓度，司机就会被警察逮捕。由此可推知，答案A符合文意。
