2019考研英语二完形填空原文
Weighing yourself regularly is a wonderful way to stay aware of any significant weight fluctuations. __1__, when done too often, this habit can sometimes hurt more than it __2__.
As for me, weighing myself every day caused me to shift my focus from being generally healthy and physically active, to focusing __3__ on the scale. That was bad to my overall fitness goals. I had gained weight in the form of muscle mass, but thinking only of __4__ the number on the scale, I altered my training program. That conflicted with how I needed to train to __5__ my goals.
I also found that weighing myself daily did not provide an accurate __6__ of the hard work and progress I was making in the gym. It takes about three weeks to a month to notice significant changes in your weight __7__ altering your training program. The most __8__ changes will be observed in skill level, strength and inches lost.
For these __9__, I stopped weighing myself every day and switched to a bimonthly weighing schedule __10__. Since weight loss is not my goal, it is less important for me to __11__ my weight each week. Weighing every other week allows me to observe and __12__ any significant weight changes. That tells me whether I need to __13__ my training program.
I use my bimonthly weigh-in __14__ to get information about my nutrition as well. If my training intensity remains the same, but I’m constantly __15__ and dropping weight, this is a __16__ that I need to increase my daily caloric intake.
The __17__ to stop weighing myself every day has done wonders for my overall health, fitness and well-being. I’m experiencing increased zeal for working out since I no longer carry the burden of a __18__ morning weigh-in. I’ve also experienced greater success in achieving my specific fitness goals, __19__ I’m training according to those goals, not the numbers on a scale.
Rather than __20__ over the scale, turn your focus to how you look, feel, how your clothes fit and your overall energy level.

1第 1 题
答案D
解析原文先肯定定期称重能察觉体重明显波动，接着用逗号引出“称得太勤有时伤害大于……”，前后语义由肯定转向转折，故选However。Besides表递进、Therefore表因果、Otherwise表否则，均无法衔接这一对比。helps与hurt构成“利弊”对举，符合“hurt more than it helps”的固定对照；cares、warns、reduces与hurt无法形成对称评价。
-
2第 2 题
答案A
解析空处需与hurt构成比较：称重过勤“伤害大于帮助”。helps与hurt形成利弊对举，语义自然。cares侧重在意、warns侧重警告、reduces侧重减少，均不能与hurt构成“弊大于利”的惯用对照，搭配也不通顺。
-
3第 3 题
答案B
解析作者称每天称重使注意力从整体健康转向“只盯秤上数字”，solely（仅仅、唯一）精确对应only of的语义。initially表起初、occasionally表偶尔、formally表正式，均无法体现“过度单一关注秤”这一负面转向。
-
4第 4 题
答案B
解析作者肌肉增加导致体重上升，却只想着把秤上数字压下去，因而改了训练。lowering（降低）贴合“减数字”的执念。recording只是记录、explaining是解释、accepting是接受，都与改变训练计划的动机不符。
-
5第 5 题
答案D
解析改训练与“为实现目标所需的训练”冲突，reach my goals即达成目标，逻辑连贯。modify、set、review分别是修改、设定、回顾目标，与“按正确方式训练去实现目标”的方向不一致。
-
6第 6 题
答案B
解析每日称重无法准确反映健身房里的努力与进步，需要的是对进展的“描绘/呈现”。depiction（描绘、写照）符合“准确反映”之义。definition是定义、distribution是分配、prediction是预测，均偏离“呈现真实进展”的语境。
-
7第 7 题
答案A
解析体重显著变化大约需三周到一个月才能因训练调整而显现，due to表原因，说明变化来自改变训练。regardless of表不论、aside from表除了、along with表伴随，都不能标明“因调整训练而产生”的因果关系。
-
8第 8 题
答案D
解析与体重滞后相对，技能、力量和围度减少会最先被察觉，immediate（即时的）对应“最先观察到”。orderly有序、rigid僵硬、precise精确，都不强调时间上的先后快慢。
-
9第 9 题
答案C
解析前文列举每日称重的种种弊端，For these reasons自然收束原因。claims主张、judgments判断、methods方法，都不能概括上文作为“所以停称”的理据。
-
10第 10 题
答案A
解析停掉每日称重，改为两周一次，instead标明方式替换。though表让步、again表再次、indeed表确实，无法体现“改用另一种日程”的替代关系。
-
11第 11 题
答案A
解析减重并非目标，因此不必每周追踪体重。track（跟踪、监测）与称重记录的目的一致。overlook忽视、conceal隐瞒、report汇报，或相反或越界，都不符“监测必要性降低”的陈述。
-
12第 12 题
答案D
解析隔周称重便于观察并解释明显体重变化。account for（说明、解释）与observe并列，指向对变化的归因。depend on依赖、approve of赞成、hold onto抓住，语义均不接“体重变化”。
-
13第 13 题
答案B
解析体重变化告诉作者是否需要调整训练计划。adjust（调整）与后文根据信息改计划一致。share分享、confirm确认、prepare准备，都不能表示根据反馈改训练安排。
-
14第 14 题
答案A
解析用双月称重的结果同时了解营养状况。results（结果）即秤上读数带来的信息。features特征、rules规则、tests测试，都不能指称一次称重所得数据。
-
15第 15 题
答案C
解析训练强度不变却总感到饿并掉秤，说明热量不足。hungry与dropping weight构成能量摄入偏低的典型组合。bored、anxious、sick虽可表不适，却与“需增加热量”的推理链条最弱。
-
16第 16 题
答案D
解析上述情况是需要增加每日热量的信号。sign（迹象、信号）符合“据此判断营养”的用法。principle原则、secret秘密、belief信念，都不能作身体反馈的标记。
-
17第 17 题
答案C
解析决定停止每日称重给整体健康带来好处。decision对应前文“stopped…switched”的主观选择。request请求、necessity必要、wish愿望，或过重或过虚，不如decision贴切。
-
18第 18 题
答案A
解析不再背负令人失望的晨称负担，锻炼热情上升。disappointing修饰称重结果常令人沮丧。surprising惊讶、restricting限制、consuming耗费，都不能准确刻画“早称数字打击心情”的负担。
-
19第 19 题
答案D
解析健身更成功，是因为按目标而非秤上数字来训练。because揭示因果。if、unless、until分别表条件、除非、直到，无法说明成功的原因。
-
20第 20 题
答案A
解析与其纠结于秤，不如关注外形、体感、衣服合身与精力。obsessing over（对……过度执着）是固定搭配。dominating主宰、puzzling困惑、triumphing获胜，都不能与over the scale构成“别再死盯秤”的劝告。
