28. What can people do at the apple events?
- A. Attend experts’ lectures.
- B. Visit fruit-loving families.
- C. Plant fruit trees in an orchard.
- D. Taste many kinds of apples.
答案：D
答案句：Visiting an apple event is a good chance to see, and often taste, a wide variety of apples.
参考译文：参观苹果活动是一个好机会，可以看到并常常品尝到各种各样的苹果。
定位线索：题干“What can people do at the apple events”→答案句“Visiting an apple event is a good chance to see, and often taste, a wide variety of apples”；文中“taste”对应选项D“Taste”；文中“a wide variety of apples”对应选项D“many kinds of apples”。
解析：题干问在苹果活动中人们能做什么，答案句直接说“Visiting an apple event is a good chance to see, and often taste, a wide variety of apples”，即可以品尝多种苹果，与D项“Taste many kinds of apples”完全对应。A项“参加专家讲座”在原文中未提及，属于无中生有；B项“拜访爱水果的家庭”曲解了原文“family affairs”（家庭活动）的含义；C项“在果园种果树”原文未提及，属于无中生有。
29. What can we learn about Decio?
- A. It is a new variety.
- B. It has a strange look.
- C. It is rarely seen now.
- D. It has a special taste.
答案：C
答案句：To people who are used to the limited choice of apples such as Golden Delicious and Royal Gala in supermarkets, it can be quite an eye opener to see the range of classical apples still in existence, such as Decio which was grown by the Romans.
参考译文：对于那些习惯了超市里有限的苹果品种（如金冠和皇家嘎啦）的人来说，看到仍然存在的经典苹果品种（如罗马人种植的Decio）会大开眼界。
定位线索：题干“What can we learn about Decio”→答案句“see the range of classical apples still in existence, such as Decio”；文中“still in existence”对应选项C“It is rarely seen now”（现在很少见，即仍存在但不多见）。
解析：题干问关于Decio我们能了解到什么，答案句提到“classical apples still in existence”，说明Decio是仍然存在的经典品种，但人们平时在超市见不到，因此“rarely seen now”（现在很少见）符合文意。A项“新品种”与“classical”（经典）矛盾；B项“长相奇怪”是文中描述Cat's Head的，不是Decio；D项“味道特别”与原文“it doesn't taste of anything special”（味道没什么特别）相反。
30. What does the underlined phrase “a pipe dream” in Paragraph 3 mean?
- A. A practical idea.
- B. A vain hope.
- C. A brilliant plan.
- D. A selfish desire.
答案：B
答案句：One of the very best varieties for eating quality is Orleans Reinette, but you’ll need a warm, sheltered place with perfect soil to grow it, so it’s a pipe dream for most apple lovers who fall for it.
参考译文：就食用品质而言，最好的品种之一是Orleans Reinette，但你需要一个温暖、有遮蔽且土壤完美的地方来种植它，所以对大多数爱上它的苹果爱好者来说，这是一个白日梦。
定位线索：题干“a pipe dream”→答案句“you’ll need a warm, sheltered place with perfect soil to grow it, so it’s a pipe dream for most apple lovers”；文中“need...perfect soil”和“so”表明条件苛刻，对应选项B“A vain hope”（徒劳的希望）。
解析：词义题需结合上下文。答案句先说种植Orleans Reinette需要“warm, sheltered place with perfect soil”，条件非常苛刻，然后用“so”引出结论“it's a pipe dream for most apple lovers”，说明对大多数人来说这是难以实现的愿望，即“vain hope”（徒劳的希望）。A项“实用的想法”与语境相反；C项“绝妙的计划”和D项“自私的欲望”均不符合上下文逻辑。
31. What is the author’s purpose in writing the text?
- A. To show how to grow apples.
- B. To introduce an apple festival.
- C. To help people select apples.
- D. To promote apple research.
答案：B
答案句：If you are a fruit grower — or would like to become one — take advantage of Apple Day to see what’s around. It’s called Apple Day but in practice it’s more like Apple Month. … Visiting an apple event is a good chance to see, and often taste, a wide variety of apples. … At the events, you can meet expert growers and discuss which ones will best suit your conditions, and because these are family affairs, children are well catered for with apple-themed fun and games. … Apple Days are being held at all sorts of places with an interest in fruit, including stately gardens and commercial orchards (果园).
参考译文：如果你是水果种植者——或者想成为其中之一——利用苹果日看看周围有什么。它被称为苹果日，但实际上更像苹果月。…参观苹果活动是一个好机会，可以看到并常常品尝到各种各样的苹果。…在活动中，你可以遇到专家种植者，讨论哪些品种最适合你的条件，而且由于这些是家庭活动，孩子们也能享受到以苹果为主题的趣味游戏。…苹果日在各种对水果感兴趣的地方举行，包括宏伟的花园和商业果园。
定位线索：题干“author’s purpose in writing the text”→首段“take advantage of Apple Day”、第二段“Visiting an apple event”、第四段“At the events”、末段“Apple Days are being held”；文中反复出现“Apple Day”和“events”，对应选项B“introduce an apple festival”。
解析：主旨题需概括全文。文章首段介绍苹果日及其时间，第二段讲活动内容（品尝苹果），第三段讲品种，第四段讲活动中的交流与儿童活动，末段讲活动地点，全文围绕“Apple Day”这一节日展开，目的是介绍这个苹果节，对应B项。A项“展示如何种苹果”只是文中部分内容，不是主旨；C项“帮助人们选苹果”是活动的一个方面，不全面；D项“推广苹果研究”文中未提及，属于无中生有。
