單項選擇題
1、根據以下資料，回答題：
        Drink from plastic bottles can raise the body's levels of a controversial "gender-bending" chemical by more than two thirds, according to tests．
        Experts have been concerned about the possible health effects of bisphenolA (BPA．--an everyday chemical used in many plastic food and drink containers and tins as well as clear baby bottles--which is officially classified as toxic in some countries．A study found that participants who drank for a week from polycarbonate (聚碳酸酯) bottles showed a 69 percent increase in their urine (尿液) of BPA．
        Researchers did not say how much liquid was drunk per day．Researchers from Harvard School ofPublic Health studied 77 students, who had first undergone a seven-day "washout" phase in which theydrank all cold beverages (飲料) from stainless steel bottles in order to minimise BPA exposure．
        They were then given two polycarbonate bottles and asked to drink all cold beverages from themduring the next week．Previous studies have suggested that high levels of BPA consumption are linked tobirth defects, growth problems and an increased risk of heart disease．In particular there are fears thatheating the bottles, as parents would do when warming their baby's milk, causes the chemical to leak inpotentially dangerous quantities into the liquid contained within．
        "If you heat those bottles, as is the case with baby bottles, we would expect the levels to beconsiderably higher．This would be of concern since infants may be particularly susceptible to BPA'shormone gland-disrupting (擾亂腺體極速分泌) potential．" said the senior author of the latest study, Karin B．Michels．
        Most adults carry BPA in their bodies but expert opinion on the risks is divided．The European Food Safety Authority believes that people naturally convert the chemical into less harmful substances in the body．
        Previous studies had found that BPA could leach (滲出 ) from polycarbonate bottles into theircontents, but this study is the first to show the size of the corresponding increase in urinary BPAconcentrations in humans．
        Harvard researcher Jenny Carwile said, "While previous studies have demonstrated that BPA is linkedto adverse health effects, this study fills in a missing piece of the puzzle--whether or not polycarbonateplastic bottles are an important contributor to the amount of BPA in the body．"

What do we know about bisphenol A (BPA．from the beginning of the passage?
A．It is certain substance taken in by human beings every day．
B．It is a component contained in a number of plastic products．
C．It is an element that plays a decisive role in people's gender．
D．It is a kind of chemical that is universally regarded poisonous．

7、詩歌是早的文學體裁，它以抒情的方式，高度集中地反映社會生活。在文字出現以前，詩歌就已經存在了，因為詩歌源于勞動。詩歌是有節奏、有韻律并富有感情色彩的一種語言藝術形式，也是世界上古老、基本的文學形式。《詩經》(Book of C | ass i c Poetry)是我國早的一部詩歌總集，它收集了自西周初年至春秋時期大約五百多年的三百零五篇詩歌，在中國文學發展史上占有突出的地位。


8、麻將是中國人主要的休閑娛樂之一。它起源于中國，其歷史可追溯到三四千年以前。麻將原是皇家和王公貴族們的游戲，在長期的歷史演變過程中，逐步從宮廷流傳到民間，到清朝中期基本定型。麻將自1920年傳入美國后。受歡迎的程度并不比在中國遜色。在南加州就常常舉辦麻將比賽。有人說，麻將之所以在國外那么受歡迎，正是源于外國人對中國古老文化的認知和認同(recogn i t i on and acceptance)。
