Are Sweeteners （甜味劑） 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．
Dietician Emma Carder says on the NHS Choices website，"While more research is needed，sweeteners continue to have a useful role in offering a sweet taste without adding（50）Dcalories．"

Answer 1

分析 本文講述了糖對人體的危害，但是甜味劑雖然沒有明顯的證據(jù)表明對人體有害，但是從長久來看，其影響還是不確定．

解答 41．G 42．C 43．A 44．J 45．E 46．B 47．K 48．F 49．H 50．D
41．G．前面提到的二號糖尿病、較肥胖的身體、血糖水平的升高等都是喜歡吃糖造成的后果，那么對牙齒的損害根據(jù)常識推斷就是易使牙齒腐爛；故選G．
42．C．前面說What's the alternative？所以接下來就是許多人建議使用甜味劑來替代糖，后面的But are sweeteners healthier than sugar？也是提示；故選C．
43．A．根據(jù)have a similar taste to sugar可知甜味劑和糖的味道是幾乎一樣的，又根據(jù)后面句子中的做目的狀語的不定式to help cut their sugar intake（減少糖分的攝入），所以有四分之一多的英國家庭購買人造的甜味劑；故選A．
 44．J．根據(jù)后面的賓語some of the health claims （一些健康聲明）可知，這是歐洲食品安全委員會批準(zhǔn)了遮羞聲明；故選J．
45．E．由and后面的controlling blood sugar levels可知，這是甜味劑的功效之一即控制血糖水平，那么對牙齒的防護自然就是防止蛀牙（preventing tooth decay ）；故選E．
46．B．sweeteners are safe to use和are（46）helpful for those who are diabetic兩者之間應(yīng)該是一種遞進(jìn)關(guān)系，所以用especially來修飾；故選B．
47．K．前面一句I support and promote the use of sweeteners in cooking and diet說明她是認(rèn)可對甜味劑的使用的，接下來就是陳述她的理由：因為低熱量的甜味劑是否對人體有害還是有不良影響是沒有相關(guān)證據(jù)的；故選K．
48．F．此處的But表示轉(zhuǎn)折，指人們還是擔(dān)心長期使用甜味劑的影響；故選F．
49．H．Dr Robert Lustig的觀點是短期內(nèi)甜味劑對人體是沒有明顯的影響的，但是就其持久的影響則是不為人知的；故選H．
50．D．最后Emma Carder指出，盡管需要進(jìn)一步研究，但是在不額外增加其卡路里含量的情況下，為人們提供甜食方面還是有著有用的作用的；故選D．

點評 在做十一選十的選詞填空題時，很重要的一點就是要確認(rèn)空格處所要填的詞的詞性，然后根據(jù)句子的語法規(guī)則，也是就是句法來判斷所要填的詞．
