Are Sweeteners （甜味剂） Safe and Healthy？
For many of us，the relationship we have with sugar is love at first taste，and that love usually lasts a lifetime．But what price do we have to pay for this truly addictive，sugary love？Type 2 diabetes （糖尿病）？Heavier bodies？Raised blood sugar levels？Or even（41）Gteeth？
Time to quit perhaps？Easier said than done．What's the alternative？Many would suggest using sweeteners as a（42）C．But are sweeteners healthier than sugar？
Sweeteners are usually low-calorie （卡路里） or calorie-free substances that have a similar taste to sugar．It is estimated that more than a quarter of British households buy（43）Asweeteners to help cut their sugar intake．
The European Food Safety Authority （EFSA） has（44）Jsome of the health claims food manufacturers have made about sweeteners such as xylitol，sorbitol and sucralose．These include（45）Etooth decay and controlling blood sugar levels．
According to the National Health Service in the UK，sweeteners are safe to use and are（46）Bhelpful for those who are diabetic．Sioned Quirke，a spokesperson for the British Dietetic Association says，"As a dietician，I support and promote the use of sweeteners in cooking and diet．"She also says that"There is no（47）Kto suggest that low-calorie sweeteners，such as saccharin，aspartame and sucralose，are harmful or bad for you．"
But many have（48）Fover the long-term effects caused by using sweeteners．Dr Robert Lustig，author of‘Fat Chance：The Bitter Truth About Sugar'would not accept sweeteners as an alternative to sugar because，"We lack data"．According to Dr Lustig，organisations like EFSA only require studies which test whether something will poison a person in a short period of time，which is known as acute toxicity （急性毒性） studies．But we still don't know what the（49）Heffects are．

Answer 1

分析 本文讲述了糖对人体的危害，但是甜味剂虽然没有明显的证据表明对人体有害，但是从长久来看，其影响还是不确定．

解答 41．G 42．C 43．A 44．J 45．E 46．B 47．K 48．F 49．H 50．D
41．G．前面提到的二号糖尿病、较肥胖的身体、血糖水平的升高等都是喜欢吃糖造成的后果，那么对牙齿的损害根据常识推断就是易使牙齿腐烂；故选G．
42．C．前面说What's the alternative？所以接下来就是许多人建议使用甜味剂来替代糖，后面的But are sweeteners healthier than sugar？也是提示；故选C．
43．A．根据have a similar taste to sugar可知甜味剂和糖的味道是几乎一样的，又根据后面句子中的做目的状语的不定式to help cut their sugar intake（减少糖分的摄入），所以有四分之一多的英国家庭购买人造的甜味剂；故选A．
 44．J．根据后面的宾语some of the health claims （一些健康声明）可知，这是欧洲食品安全委员会批准了遮羞声明；故选J．
45．E．由and后面的controlling blood sugar levels可知，这是甜味剂的功效之一即控制血糖水平，那么对牙齿的防护自然就是防止蛀牙（preventing tooth decay ）；故选E．
46．B．sweeteners are safe to use和are（46）helpful for those who are diabetic两者之间应该是一种递进关系，所以用especially来修饰；故选B．
47．K．前面一句I support and promote the use of sweeteners in cooking and diet说明她是认可对甜味剂的使用的，接下来就是陈述她的理由：因为低热量的甜味剂是否对人体有害还是有不良影响是没有相关证据的；故选K．
48．F．此处的But表示转折，指人们还是担心长期使用甜味剂的影响；故选F．
49．H．Dr Robert Lustig的观点是短期内甜味剂对人体是没有明显的影响的，但是就其持久的影响则是不为人知的；故选H．
50．D．最后Emma Carder指出，尽管需要进一步研究，但是在不额外增加其卡路里含量的情况下，为人们提供甜食方面还是有着有用的作用的；故选D．
