14、知，作者由于特别想家，所以想要放弃体操。故B项符合题意。12A细节理解题。根据文章第三段“Youre breaking my heart，Brie.”可知，妈妈听说我要半途而废感到心碎。故选A项。13C推理判断题。根据文章最后一段“Exactly 210 days before I ever attempted my first vault (跳跃) in the London Summer Olympics”可知，作者在210天后参加了伦敦奥运会，因此可推断出，作者最后改变了主意，并没有放弃体操。故选C项。14B主旨大意题。作者最初想放弃体操，但最后选择了坚持。B项标题概括了文章的主旨并与文

16、erent species the way they are? Why are there so many flies and so few wolves? To find an answer，scientists have built mathematical models of food webs，noting who eats whom and how much each one eats.With such models，scientists have found out some key principles operating in food webs.Most food webs
17、，for example，is made up of many weak links rather than a few strong ones.When a predator(掠食动物) always eats huge numbers of a single prey(猎物)，the two species are strongly linked; when a predator lives on various species，they are weakly linked.Food webs may be dominated (支配) by many weak links because
18、 that arrangement is stabler over the long term.If a predator can eat several species，it can survive the extinction of one of them.And if a predator can move on to another species that is easier to find when a prey species becomes rare，the switch allows the original prey to recover.The weak links ma
19、y thus keep species from driving one another to extinction.Mathematical models have also shown that food webs may be unstable，where small changes of top predators can lead to big effects throughout entire ecosystems.In the 1960s，scientists pointed out that predators at the top of a food web had a su

28、When a predator (掠食动物) always eats huge numbers of a single prey(猎物), the two species are strongly linked”可知，当捕食者总是吃大量的单一猎物，这两个物种是紧密相连的。故选C。18D推理判断题。根据第三段“predators at the top of a food web had, a surprising amount of control over the size of populations of other species they did not directly attack
29、”可知，处于食物链顶端的食肉动物对它们没有直接攻击的其他物种的种群数量有着惊人的控制，由此可推断出，如果食物链顶端的食肉动物的数量大大下降，其他物种的种群将经历意想不到的变化。故选D。19A推理判断题。根据第五段“Ideally, the system would tell us when to adapt human activities that are pushing an ecosystem toward a breakdown or would even allow us to pull an ecosystem back from the borderline.”可知，人类过度的活
30、动会将生态系统推向崩溃，由此可推断出，不受控制的人类活动极大地破坏了生态系统。故选A。20D细节理解题。根据最后一段可知，早期预警系统发出紧急需要采取预防行动的信号帮助我们维持生态平衡。故选D。阅读加油站fly n. 苍蝇breakdown n. 故障；崩溃Ideally, the system would tell us when to adapt human activities that are pushing an ecosystem toward a breakdown or would even allow us to pull an ecosystem back from the
31、 borderline.在理想情况下，该系统会告诉我们什么时候去调整正在推动生态系统崩溃的人类活动，甚至可以让我们将生态系统从边界线拉回来。第二节(共5小题；每小题2分，满分10分)Recently some American scientists have given a useful piece of advice to people in industrialized nations.They say people should eat more of the same kind of food eaten by humans living more than 10,000 years

37、明病”的兴起。要阻止这种现象就要回到石器时代向古人学习。21C前面提到“建议人们回到10, 000多年前，像当时的人们那样吃东西”，为什么呢？后续语境给出答案：为了健康。故选C。22E上文提到，我们的身体不能应对生活方式的改变，因此带来了一些新的疾病，现在人们称之为“文明病”，而以前呢？在古代却没有听说过这些疾病。故选E。 23D此处关联语境为新石器和旧石器时代人们的生活方式，5个选项中只有D与之匹配：古人也有很多体育锻炼。因此D项符合语境。 24B前面为古人的饮食特点，下文为现代人的饮食结构，而此处承上启下，作为过渡。故选B项(但是今天，我们喜欢吃很多这样的东西)。25F所在部分为全文结论。
38、But表转折，后面为科学家建议的饮食结构，故空格处应表达与此相反的内容，故选F项(今天的人们可能不想像我们的祖先那样生活)。第三部分完形填空(共15小题；每小题1分，满分15分)My life as a tax-paying employed person began in middle school, when, for three whole days, I worked in a baking factory.My best friend Betsys father was a manager at Hough Bakeries, which, at Easter time, _26_

44、preciate【语篇解读】本文讲述了作者上中学时去一家烘焙工厂做临工的经历，告诉我们要珍惜自己的工作所得，也要尊重他人的辛勤劳动。26C根据 “Hough Bakeries”可知，烘焙店在复活节期间要“制作(made) ”小兔子蛋糕。27A“its” 指代“Hough Bakeries”，故只能是它的所有“商店(stores )”。28D根据前面的“It happened that the plant downtown needed eight kids”和“help during our spring break”可知，烘焙店在春假期间需要八个孩子“临时( temporary)”帮忙。29
45、A“which” 指代“spring break”。根据第一段中的“worked in a baking factory”和本句中的“beyond listening to my favorite records”可知，作者在春假时除了听最喜欢的唱片外没有别的“计划(plans) ”。30B根据第一段中的“tax-paying employed person”可知，作者“挣(earn) ”最低工资。此处的“earn”与文末的“earned”构成原词复现。31A去烘焙店工作将使作者了解一个工厂如何“运转(worked)”。32B根据前面的“My parents thought all of th
46、is was a grand idea and called Betsys dad”可知，作者的父母认为去打临工是好事，于是给贝琪的父亲打电话，“允许(permission)”作者去工作。33C根据冒号后的“Place cakes on a moving belt”可知，把蛋糕放到传送带上是作者在工厂的“任务(roles)”。34D根据下文中的“the cakes pile up”可知，作者的任务包括把兔子蛋糕从传送带上“移走(remove)”。35A这个工作比听起来“更难(harder) ”。36B动作稍“慢(slow down)”一点蛋糕就会堆积起来。37C根据前面的“it was a l
47、ittle more high-pressure”可知，上班的第一天晚上，作者告诉父母这项工作的压力超出了自己的“预期(expected)”。38B根据下文父亲对这项工作的正面评价可知，父亲“笑了(smiled) ”。39D根据前面的“The son of a grocer”可知，作为食品杂货商的儿子，父亲童年时的暑假会“递送(delivering) ”货物。40D根据“respect those who did the work”可知，父亲告诉作者：这项工作让作者“珍惜(appreciate)”自己挣的钱并敬重做这项工作的人们。第四部分语法填空(共10小题；每小题1.5分，满分15分)Ani
