　　(2016·山东潍坊第一中学高三4月过程性检测)A glass a day keeps obesity at bay.Alcohol has always been thought to cause weight gain because of its high sugar content，but new research suggests a glass a day could form part of a diet.Looking at past studies，they found that while heavy drinkers do put on weight；those who drink in_moderation can actually lose weight.

　　A spokesman for the research team at Navarro University in Spain says，“Light to moderate alcohol intake，especially of wine，may be more likely to protect against，rather than promote，weight gain”．The International Scientific Forum on Alcohol Research reviewed the findings and agreed with most of the conclusions，particularly that current data do not clearly indicate if moderate drinking increases weight.

　　Boston University’s Dr.Harvey Finkel found that the biologic mechanisms (生物学机制) relating alcohol to changes in body weight are not properly understood.His team pointed out the strong protective effects of moderate drinking on the risk of getting conditions like diabetes (糖尿病)，which relate to increasing obesity.Some studies suggest that even very obese people may be at lower risk of diabetes if they are moderate drinkers.

　　The group says alcohol provides calories that are quickly absorbed into the body and are not stored in fat，and that this process could explain the differences in its effects from those of other foods.They agree that future research should be directed towards assessing the roles of different types of alcoholic drinks，taking into consideration drinking patterns and including the past tendency of participants to gain weight.

　　For now there is little evidence that consuming small to moderate amounts of alcohol on a regular basis increases one’s risk of becoming obese.What’s more，a study three years ago suggested that resveratrol，a compound present in grapes and red wine，destroys fat cells.

　　(2016·唐山模拟)The spread of Western eating habits around the world is bad for human health and the environment.These findings come from a new report in the journal Nature.

　　David Tilman，a professor of ecology at the University of Minnesota，America，examined

　　information from 100 countries to identify what people ate and how a diet affected health.He noted a movement beginning in the 1960s.He found that as nations industrialized (工业化)，population increased and earnings rose，more people began to adopt what has been called the Western diet.

　　The Western diet is high in sugar，fat，oil and meat.By eating these foods，people began to get fatter and sicker.David Tilman says overweight people are at greater risk of non­infectious diseases like diabetes (糖尿病) and heart disease.

　　Unfortunately when people become industrialized，if they adopt this Western diet，they are going to have these health problems，especially in developing countries in Asia.China is an example where the number of diabetes cases has been jumping from less than one percent to 10 percent of the population as they began to industrialize over a 20­year period.And that is happening all across the world，in Mexico，in Nigeria and so on.

　　And，a diet bad for human beings，is also bad for the environment.As the world’s population grows，more forests and tropical (热带的) areas will become farmlands for crops or grasslands for cattle.We are likely to have more greenhouse gas in the future from agriculture than that coming out of all forms of transportation right now.

　　Mr.Tilman calls the link between the diet，the environment and human health，“a trilemma”—a problem offering a difficult choice.He says one possible solution is leaving the Western diet behind.

　　【文章大意】　《自然》杂志上一篇新的报告表示，西方饮食对人的健康和环境有不良影响，人们应警惕西方饮食带来的危害。

　　5．According to the passage，more greenhouse gas might be given off in the future from ________.

　　A．transportation

　　B．developing countries

　　C．agriculture

　　D．developed countries

　　解析：选C。细节理解题。根据倒数第二段的最后一句“We are likely to have more greenhouse gas in the future from agriculture than that coming out of all forms of transportation right now.”可知，未来更多的温室气体排放可能来自于农业，故选择C项。

　　6．David Tilman believes that

　　________.

　　A．the diet，the environment and human health are closely connected

　　B．the Western diet is the only choice as the nation industrializes

　　C．people in tropical areas are more likely to have heart disease

　　D．traditional diets are more balanced than the Western diet

　　解析：选A。推理判断题。根据最后一段的第一句“Mr.Tilman calls the link between the diet，the environment and human health...a difficult choice.”可知，Tilman先生把日常饮食、环境和人的健康之间的联系称为三难困境。由此可知，它们三个是紧密相关的，故选择A项。

　　7．We can infer from the passage that ________.

　　A．Nigeria has the largest number of diabetes cases

　　B．overweight people are at higher risk of infectious diseases

　　C．the examined information comes from developing countries

　　D．industrialization contributes to the spread of the Western diet

　　解析：选D。推理判断题。根据第二段的最后一句“He found that as nations industrialized (工业化)，population increased and earnings rose，more people began to adopt what has been called the Western diet.”可推知，工业化、人口增长和收入增加造成了西方饮食的传播，故D项正确。

　　8．The main purpose of the passage is to ________.

　　A．call on us to protect the environment

　　B．warn us of the danger of the Western diet

　　C．remind us of the importance of health

　　D．advise us to have a balanced diet
