Question

The findings come 1 a study of nearly 1,000 US people that looked at diet, calorie intake and body mass index (BMI) - a measure of obesity.2 is found that those who ate chocolate a few times a week were, on 3, slimmer than those 4 ate it occasionally. Even though chocolate is loaded with calories, it contains ingredients(材料)that may favour weight loss 5 than fat synthesis, scientists believe.6 boosting calorie intake, regular chocolate consumption was related to lower BMI in the study, 7 is published in Archives of Internal Medicine. The link remained even when other factors, like how 8 exercise individuals did, were taken into 9.And it appears it is how often you eat chocolate that is important, rather than how much of it you eat. The 10 found no link with quantity consumed.
11 to the researchers, there is only one chance in a hundred that their findings could be explained by chance alone. Lead author Dr Beatrice Golomb, from the University of California at San Diego, said: "Our findings appear to add to a body of information suggesting that the composition of calories, not just the number of them, matters for determining their ultimate impact on weight."This is not the first time scientists 12 that chocolate may be healthy for us. Other studies have claimed chocolate may be good for the heart. Consumption of certain types of chocolate has been linked to some favourable changes in blood pressure, insulin(胰島素)sensitivity and cholesterol(膽固醇)level. And chocolate, 13 dark chocolate, does contain antioxidants(抗氧化劑)which can help to mop up harmful free radicals - unstable chemicals that can damage our cells.
Dr Golomb and her team believe that antioxidant compounds, called catechins(兒茶素), can improve lean muscle mass and reduce weight 14 studies in rodents would suggest this might be so. Mice 15 for 15 days with epicatechin (present in dark chocolate) had improved exercise performance and observable changes to their muscle composition.They say clinical trials are now needed in humans to see 16 this is the case.
But before you reach 17 a chocolate bar, there are still lots of unanswered questions. And in the absence of conclusive evidence, experts advise caution.While there's no harm in allowing yourself a treat like 18 now and again, eating too much might be harmful because it often 19 a lot of sugar and fat too.And if you are looking to change your diet, you are 20 to benefit most from eating more fresh fruits and vegetables.

文章講述的是一項研究發(fā)現(xiàn)巧克力的經(jīng)常攝入有助于人們的身體質(zhì)量。
1.詞組搭配，come from來自，來源于 句意為這個發(fā)現(xiàn)來源于一個研究。
2.固定句型，It is found that ........it作形式主語，代指后面的that從句。
3.詞組。On average 平均
4.定語從句，根據(jù)句意可知此處為定語從句指的是those，指人，
5.詞組。Rather than 而不是
6.句意理解。此處句意為盡管卡路里吸收的增加，經(jīng)常性的巧克力的攝入與低的身體質(zhì)量指數(shù)是有關(guān)的。
7.非限制性定語從句，指代前面的一句話。
8.因為exercise作鍛煉講時是不可數(shù)名詞，所以選擇how much。
9.固定短語，take sth into account/consideration 考慮
10.上下文，根據(jù)文章第一段第一句話可知，文章講述的是該研究的結(jié)果，所以此處是研究沒有發(fā)現(xiàn)與巧克力的量的關(guān)系。

14.詞組辨析，at least 至少 at most至多 in fact事實上 by accident 偶然，意外地
15.mice和feed之間是被動關(guān)系，此處作mice的定語，="which" were fed
16.句意理解，此處意為他們說還需要人體的臨床試驗來看是否是這樣的。
17.詞組reach for a chocolate伸手去拿巧克力
18.上下文，文章主要在講巧克力。
19.動詞辨析，contain意為包含某種物質(zhì)，此處意為巧克力含有大量的糖。
20.當(dāng)主語是人的時候，只能選擇likely意為，某人很可能干某事。
