　　Is Chocolate Good for You?

　　It's a perennial question and，thanks to the research published this week by scientists at Imperial College，London，claiming that the theobromine in chocolate is a third effective than codeine at stopping persistent coughs，one that is being asked again week.

　　So. to run through those health benefits:in 2001·a study published in the Lancet showed that chocolate contained significant amounts of antioxidants in the form of flavinoids一these prevent the build-up of coronary artery plaque. In particular, catechin(also found in tea) protects the immune system and the heart.It reinforced a study carried out two years earlier at the University of Scranton，which showed that flavinoids were even better than vitamin C in preventing the bad LDL cholesterol in the blood from being oxidised and damaging the heart. Chocolate also contains several trace minerals including manganese. potassium，magnesium，phosphorus and calcium.

　　But this is no licence to gorge.Chocolate contains lots of saturated fat(in the form of stearic acid)and sugar while fruits and vegetables contain more of the antioxidant flavinoids. In 1999，a study published in the American Journal of Clinical Nutrition showed that the risk of coronary heart disease thanks to the fat in chocolate was even more than the risk posed by other harmful fats. As the editorial in that issue concluded:

　　“Unfortunately·for chocolate lovers. chocolate's high content of stearic acid puts it in the same category of risk of coronary disease as meat and butter一i. c. pathogenic.”

　　Therefore，even if theobromine proves to be the best way to treat persistent coughs in the future，it's more likely that your doctor will prescribe you a pill than a Mars bar.

　　The solution?Eat bitter dark chocolate.which contains less of the bad stuff but still has the flavinoids.

　　4 .Eating chocolate helps people to be more energetic in their work.

　　解析

　　1.答案為FALSE,題目中的說法是，吃巧克力對(duì)人好不好這一問題的辯論很快就要結(jié)束了(is soon to be over)。乍一看，文章中好像沒有提到這樣的辯論會(huì)持續(xù)多久，但文章第一段的起始句中有一個(gè)詞是關(guān)鍵: perennial，意思是“長(zhǎng)期的、長(zhǎng)久的”，這就表明了這一問題的持久性，并不會(huì)很快就結(jié)束，題目的說法與原文形成反義結(jié)構(gòu)。

　　2.答案為TRUE.題目中提到，巧克力中對(duì)健康有益的成分是flavinoids和一些trace minerals，這些都可以在文章的第二段起始句和結(jié)束句中找到答案。

　　3.答案為FALSE,題目中包含了一個(gè)原因狀語從句，因?yàn)榍煽肆χ泻瑢?duì)人健康有益的成分.

　　所以人們可以想吃多少就吃多少，而在第三段中明確指出.盡管巧克力中含對(duì)人健康有益的成分，但也不是說就可以放開了吃(no licence to gorge).題目的說法與原文相反。

　　4.答案為NOT GIVEN。本文討論的是巧克力對(duì)人們身體健康是否有益，提到巧克力含哪些有益健康的成分，對(duì)健康有哪些不好的影響，出現(xiàn)的都是一些較為專業(yè)的醫(yī)學(xué)詞匯。文中并沒有提到吃巧克力會(huì)不會(huì)使人在不作中保持精力充沛，題目屬于未給出的信息。

　　5.答案為TRUE,綜合上文，巧克力中既含有益健康的成分，又含有害健康的成分，解決的辦法(solution)就是吃黑巧克力，因?yàn)樗娑嘤诤?。雖然原文中并沒有出現(xiàn)題目中的比較結(jié)構(gòu)，但通過推斷，黑巧克力一定優(yōu)于其他巧克力，否則也不會(huì)被作為solution的。題目與原文意思吻合。
