Eat healthier without quitting sugar
Not long ago, fat was regarded as the evil for a healthy diet. Before that it was salt. Now the sugar-free diet ____21____ (explode) onto the health scene —and seems to have topped many people’s list of New Year’s resolutions.
Sugar-free diets encourage people to avoid sweeteners such as honey, soft drinks and some fruits. Some also recommend ____22____ (restrict) dairy products. The diet’s advocates note that excessive sugar consumption may increase the risk of heart disease and some cancers. So many sugar-free followers avoid milk, yoghurt and cheese ______23______ the assumption that these products contain sugars. It’s true we are swallowing too much of the sweet stuff, with the average American consuming around 20 teaspoons of ____24____ (add) sugar a day. But you don’t need ____25____ (quit) sugar for healthy eating. Quitting sugar is unlikely to improve your health any more than cutting down on over-processed foods and eating more vegetables.
Research shows dieting is not effective over the long term and can lead to greater weight gain over time. The brain interprets dieting and restriction as hunger, ____26____ causes the storage of fat. Besides, the sugar-free diet is confusing and imposes a set of rules that ____27____ (make) up without scientific evidence.

This may be ____28____they are worried about their weight, or about the impact certain nutrients have on their health.
Through series of experiments, ____29____ the researchers are certain about is that you can eat plenty of plants, enjoy whole grains and beans. Fruit is your friend, not your enemy. Most people could probably eat a little less sugar, a little ____30____ (often), but you don’t have to quit it for good to be healthy. 【答案】21. has exploded 22. restricting
23. due to/ owing to/ because of 24. added 25. to quit 26. which 27. are made/have been made 28. because 29. what 30. less often

这是一篇议论文。无糖饮食已经爆炸式地进入健康领域，节食的倡导者认为过量的糖摄入可能会增加患心脏病和一些癌症的风险，所以一些人们避免吃甜食，一些人还建议不要吃乳制品。然而，研究表明，长期而言，节食是无效的，而且随着时间的推移，会导致体重增加。此外，无糖饮食令人困惑，并强加了一套没有科学证据的规则。这种限制性的饮食会造成对食物的恐惧或产生对食物不健康的看法。所以可以偶尔少吃一点糖，但不必为了健康而放弃糖。 【21题详解】
考查现在完成时。句意：现在，无糖饮食已经在健康领域炸开了锅，而且似乎已经成为许多人新年计划的首选。分析句意可知，本句为现在完成时，主语为sugar-free diet ，所以谓语为has exploded。故填has exploded。 【22题详解】
考查动名词。句意：一些人还建议限制奶制品的摄入。recommend doing sth“建议做某事”为固定短语。故填restricting. 【23题详解】
考查介词短语。句意：很多无糖的追随者不吃牛奶、酸奶和奶酪，由于他们认为这些产品含有糖分。分析句意可知，由于很多无糖的追随者认为这些产品含有糖分，所以他们不吃牛奶、酸奶和奶酪。所以空处填due to/ owing to/ because of“由于” ，其中to/of为介词后接名词assumption作宾语。故填due to/ owing to/ because of。
【24题详解】
考查形容词。句意：的确，我们正在吞下太多的甜食，平均每个美国人每天大约消耗20茶匙的添加糖。这里指的是被添加的糖，所以用ed结尾的形容词修饰名词。added“添加的”为形容词修饰名词sugar。故填 added。 【25题详解】
考查动词不定式。句意：但是你不需要为了健康的饮食而停止吃糖。need to do sth“需要做某事”为固定短语。故填 to quit . 【26题详解】
考查关系代词。句意：大脑将节食和对事物的限制解读为饥饿，这会导致脂肪的储存。分析句子可知，本句为which引导的非限制性定语从句，which代替前面的整个句子，作后面定语从句的主语。故填which . 【27题详解】
考查一般现在时的被动语态/现在完成时的被动语态。句意：此外，无糖饮食令人困惑，并强加了一套没有科学依据的规则。分析句子可知， a set of rules 为先行词，在后面的定语从句中作主语。且与谓语make为被动。分析句意可知，本句为一般现在时/现在完成时。故填are made/have been made。 【28题详解】
考查从属连词。句意：这可能是因为他们担心自己的体重，或者担心某些营养物质会对健康产生影响。分析句子可知，本句为表语从句。分析句意可知，空处缺少表示原因的连接词，所以空处填because。故填 because。 【29题详解】
考查连接代词。句意：通过一系列的实验，研究人员确定的是，你可以吃大量的绿色食品，享受全谷物和豆类食物。分析句子可知，本句为主语从句，about为介词，缺少宾语，所以用what作about的宾语。故填what 。 【30题详解】
考查副词比较级。句意：大多数人可以偶尔吃一点糖，但你不必为了健康而戒掉它。由“a little less sugar”less often。可知，大多数人可以少吃一点糖，但不要经常吃糖。所以用often比较级的否定形式，故填less often。 【点睛】定语从句的关系词的选择可考虑以下三点：
(1) 一看先行词的意义，即分清先行词是指人、指物、时间、地点还是原因(如指物时不能用who或whom，指人时通常不用which等)。
(2) 二看关系词的句法功能，即分清关系词是担任什么句子成分，是作主语还是宾语、是作定语还是状语等(如作定语通常用whose，有时也用which；作状语要用when, where, why)；
(3) 三看定语从句的种类，即分清是限制性定语从句还是非限制性定语从句(如that和why通常不引导非限制性定语从句)。
分析小题6的句子可知，本句为which引导的非限制性定语从句，which代替前面的整个句子，作后面定语从句的主语。故填which .
