2.Like many Czechs (捷克人),Luká? Bern?,38,enjoys going out to the pub with his friends for conversation and a few beers."I don't drink every day,"he says."I think about three times a week.When I go out,I usually have five to six beers at a time,about the same as my friends."The beers are half-liters,or 500 ml each.
If a half-liter of four-percent beer contains 16g of pure alcohol(酒精),Bern? and his friends are drinking 80 to 96 grams of pure alcohol on each outing.The Czech Republic's National Institute of Public Health,however,suggests that men take in fewer than 24g of pure alcohol per day; women,fewer than 16g.
Medical experts in over 40 countries around the world have agreed that drinking"too much"can cause harm.What they can't seem to agree upon is just how much is"too much."National safety levels are quite different,from a limit of 10g a day in the Netherlands to Denmark's 60g.
There are a number of reasons for this.Dr.Larry Altshuler,a medicine expert for the Cancer Treatment Centers in Tulsa,explains that while everything is based on research,"Every group,race,and gender responds to alcohol differently."
Also,researchers aren't using the same models or methods.He adds,"It can be like apples and oranges.How do you measure alcohol?Units,drinks,bottles or cans?What's the alcohol content(含量)?Is it light or heavy?"While a half-liter of four percent beer contains 16g of pure alcohol,a half-liter of five percent lager contains 20g.
Constance Scharff,a director of Addiction Research at Cliffside Malibu Treatment Center in California,says she believes the reason"is largely cultural.""But the evidence is clear that the more you drink,the more likely you are to develop alcohol-related health problems."

分析 本文主要講述了在不同的國家酒精標(biāo)準(zhǔn)量是不同的,它歸結(jié)于各種原因--有文化差異以及測量標(biāo)準(zhǔn)的不同等.
解答 27.C 細(xì)節(jié)題.根據(jù)文章內(nèi)容,Like many Czechs (捷克人),Luká? Bern?,38,enjoys going out to the pub with his friends for conversation and a few beers."I don't drink every day,"he says."I think about three times a week.When I go out,I usually have five to six beers at a time,about the same as my friends."The beers are half-liters,or 500 ml each.由此可知,38歲的捷克人Luká? Bern?喜歡和朋友外出喝酒,他說,他不會每天都喝酒,但是和朋友外出會和一些酒,由此推斷第一段是引出喝酒這個話題.結(jié)合選項,故選C
28.D 詞義猜測題.根據(jù)文章內(nèi)容,"National safety levels are quite different,from a limit of 10g a day in the Netherlands to Denmark's 60g…There are a number of reasons for this.每個國家對酒精的安全標(biāo)準(zhǔn)程度規(guī)定不一樣,對于這個現(xiàn)象,原因是多種多樣的.結(jié)合選項,故選D
29.C 細(xì)節(jié)題.根據(jù)文章內(nèi)容,He adds,"It can be like apples and oranges.How do you measure alcohol?Units,drinks,bottles or cans?What's the alcohol content(含量)?Is it light or heavy?".. Center in California,says she believes the reason"is largely cultural.由此可知,決定一個國家酒精標(biāo)準(zhǔn)量的原因主要是文化差異和測量標(biāo)準(zhǔn)的不同.結(jié)合選項,故選C
30.B 主旨題.根據(jù)文章內(nèi)容,主要講述了在不同的國家酒精標(biāo)準(zhǔn)量是不同的,它歸結(jié)于各種原因--有文化差異以及測量標(biāo)準(zhǔn)的不同等.結(jié)合選項,故選B
點評 本文是人物故事類閱讀理解.做這類題材閱讀理解時要求考生對文章通讀一遍,做題時結(jié)合原文和題目有針對性的找出相關(guān)語句進行仔細(xì)分析,結(jié)合選項選出正確答案.推理判斷題也是要在抓住關(guān)鍵句子的基礎(chǔ)上合理的分析才能得出正確答案,切忌胡亂猜測,一定要做到有理有據(jù).
