  【試題】

  [22] An average person consumes 144 pints of milk a year, but 40% of that is poured on the cereal and 60% of those people are children. But what was once advertised as nutrition is becoming unpopular. Americans drinks 37% less milk than they did in the 1970s. And in the UK, dairy consumption overall has fallen by a third in the past 20 years. [23] Milk is increasingly being described in a negative light. A recent blog suggested that maybe people are drinking less milk because it is poisonous to many of us. Lactose is the sugar found in milk in dairy products. it needs a series of complex proteins to break it down. Without enough of these proteins, [24]the lactose is broken down by bacteria in a human body. This can cause physical pain and produce gas in the stomach. However, after we have finished breast and formula feeding, most of us don't continue producing the complex proteins in our bodies, which are necessary to break down the lactose. Despite the problems that I just see in milk, it does provide many benefits. [25] Milk is nutritious, it contains vitamins A and D as well as protein and isn’t full of calories. You can test yourself by drinking a large glass of milk. If you get sick in your stomach within the next 24hrs, you are lack in the proteins to digest milk.

  Question 22 to 25 are based on the passage you have heard.

  22 what does the passage say about Americans?

  23 how do Americans and British think of milk nowadays?

  24 why does drinking milk cause pain in some people?

  25. What does the passage say is a benefit of milk?

  【答案】

  (見上文劃線部分)

  【解析】

  Q22.第一題符合【開頭首1-3句出題的原則】,從關鍵字對照和同義詞替換出來可以找到答案。并且,聽力技巧講過要求注意帶數字的地方,可以找到相應的材料對應部分。

  Q23 第二題,提示詞increasingly和negative可以判斷出人們對于牛奶的負面看法。并且后續的recent blog中提到的內容,也是我們在聽力技巧中經常說到的【報告,博客,某人說的話】要注意的原則,也可以很好的反應出來這個選項。

  Q24 這個題,關鍵字對照就可以,屬于原詞重現。

  Q25 這個題,也是原詞重現,只要抓住關鍵詞,這個題不難。

  【聽力述評】

  本篇文章講述了人們現在對于牛奶的看法。從以前大肆廣告到現在發現了lactose乳糖在人中的不良反應引出對牛奶的負面情緒。出題模式符合聽力技巧:如原詞對照,同義詞替換,和注意【某某人說的話】的出現等。除23略微多點理解以外,其他都不難。
