If your BMI or waist circumference is above the healthy range you' re at increased risk of diabetes, Cardiovascular disease and certain cancers such as colon, prostate and breast cancer. You're also more likely to experience joint problems and back pain, and may find you become breathless and have difficulty sleeping. The more weight you gain, the more severe these problems may become. Losing weight depends on energy balance. If you consume more energy from food and drink than you burn through maintaining your body' s functions and physical activity, you'll gain weight. Cutting calories by reducing how much you eat and drink, and increasing how much physicalactivity you do will make you lose weight. If you reduce your daily energy intake to around 500 calories (kcal) below your energy requirements ,you'll lose about 0.5kg a week. This is a sensiblerate of weight loss. Before you start making changes to your lifestyle, it' s important to ask yourself if this is the right time. The reasons you decide to lose weight will be personal to you. You might find you' re more successful if you choose a relatively calm time in your life to start. Whatever you decide, make sure you' re feeling positive and ready for the challenge. Set achievable goals. Aim to lose about five to ten percent of your initial body weight over a few months. Research shows this kind of weight loss is achievable and will improve your health. Once you' ve reached your goal, congratulate yourself and set another five per cent weight loss target. This way, you'll feel good about achieving small steps, rather than getting clown because it' s taking you so long to lose a large amount of weight. You may lose more weight in some weeks than in others, but as long as your weight continues to decrease overall there' s no need to worry. If your weight stays the same for a week or two, don' t aband on all you' ve achieved. Instead, focus on the amount and type of food you' re eating andtry to be a little more active.

What is a sensible rate of weight loss?
【正确答案】
C
【答案解析】文章第二段最后一句话：“If you reduce your daily energy intake to around 500 calories (kcal) below your energy requirements, you'll lose about 0.5kg a week. This is a sensible rate of weight loss.”解释了最合理的减重速率就是“每天将你的热量摄入减少到500卡路里左右，低于你所需要的热量，你将每周减掉大约0.5公斤的体重。”A、B、D三项的表达都不符合文中的意思，故选C。

In paragraph 4, by saying "Set achievable goals", the writer means
【正确答案】
B
【答案解析】文章第四段从第二句起开始阐述“Set achievable goals”的意思。“Aim to lose about five to ten percent of your initial body weight over a few months. ……Once you've reached your goal, congratulate yourself and set another five percent weight loss target, This way, you'll feel good about achieving small steps, rather than getting down because it's taking you so long to lose a large amount of weight.”作者根据研究的结论提出“先确立目标在几个月里减掉你初始体重的5%到10%。一旦你达到了这个目标，祝贺你自己，然后再确定另一个5%的减重目标。这样，你对于小目标的实现感觉良好，胜过你因为需要很长时间来减掉大量体重而感到沮丧。”对比答案中四个选项的描述，只有B是符合作者意思的。

If your weight stays the same for a week or two, you should not
【正确答案】
A
【答案解析】文章最后两句“If your weight stays the same for a week or two, don't abandon all you've achieved. Instead, focus on the amount and type of food you're eating and try to be a little more active.”作者交代：“如果你的体重在一两周里保持原状，不要放弃你的努力成果，而要关注你所吃食物的总量和类型，并且试着更为积极。”所以不应该做的事恰恰是A项的“give up”(放弃)，其他几项都和原文意思相符。

According to this article, which of the following is NOT tree for losing weight?
【正确答案】
C
【答案解析】A项是文章第二段的第一句原话，所以是正确的，排除；B项是文章第四段第一句和第二句的综合，也是文章要表达的意思，故排除；而D项在文中第三段中间有一句“You might find you're more successful if you choose a relatively calm time in your life to start.”正好表达了此意。只有C项文中并没有相关意思的表达，只有一句“The reasons you decide to lose weight will be personal to you.”提到了减肥的理由是很私人的。每个人可能有不同的理由，并非一定要在减肥前找到个好理由，只要自己能积极面对就行。所以，C项是不符合文意的。
