文体小知识：What the passage is about.
§课文原文 Passage
1Bees are amazing insects, and there is so much to learn about them. They live in colonies with thousands of members. Each bee has a job, and together they work like one big family. The queen bee lays eggs, while worker bees collect nectar from flowers and fly home with it.
2Worker bees turn the nectar into honey, and people have loved honey for thousands of years. Bees also pollinate plants as they fly from flower to flower. Pollen helps plants grow fruit and vegetables. This means bees do not only make honey; they also help our farms. In fact, about one third of our food depends on bees.
3Without bees, we would have no food, so we must protect them. We should not use harmful chemicals in gardens, and we should plant more flowers. Good readers find the main idea of a paragraph by looking at its topic sentence and asking, 'What is this paragraph mostly about?' The other sentences are details that support the main idea. Even the title can give you a clue about the focus of the whole passage. If you write a short summary, you will remember what you read much better.

3逐步讲解 Steps
- 首句考点是辨认段落主旨的位置。主旨多数出现在段落的第一句，开门见山点出全段中心，例如 Bees are amazing insects. 说明文常用总起句开头，先概括后解释；读首句时问自己：全段是否都在解释这一句？若是，它便是主旨句，读其余句子只为印证。易错之处是把首句当成普通引入句匆匆跳过，错过最快的定位方法；先读首句、后读全段，是找主旨的第一步，也是最省时的一步。
- 尾句有时主旨在段尾，作者先举例再总结，例如 In short, bees live like one big family. 考点是总结讯号词的辨认：见到 in short、in conclusion、therefore 等词，主旨多半就在附近，要放慢速度细读。方法是把讯号词当成路标，一见路标便集中精神。易错之处是不耐烦读到结尾便停下，错过总结句；文章的安排千变万化，首句找不著主旨，便到尾句去找，两处合看最稳妥。
- 小节考点是分清主旨与支持小节。支持主旨的小节是具体细节，例如数字、例子与描写：The queen lays eggs. Thousands of members each have a job. 这些都是小节。小节回答 how、what、why 等细节问题；主旨则概括全段，两者不可混淆。易错之处是选了只概括某个小节的选项；判别方法是看该句能否涵盖全段所有内容，能包举全局的才是主旨，只讲一事的便是细节，答题前先作这个测试。
- 标题考点是为段落选择标题。标题是短语而非完整句子，例如 Life in a Bee Colony。好标题要概括全段又够精炼：太窄便只讲某个小节，太宽便超出段落范围，两者都不合适。方法是把每个选项与全段比对，看覆盖面是否恰当。易错之处是被生动的字眼吸引，选了只涵盖细节的选项，忘了标题必须统摄全段；先排除太窄与太宽的选项，剩下的便是答案，这是选标题题的稳妥次序。
- 蜜蜂段实战考点是实战验证：以蜜蜂段落为例，段首 Bees are amazing insects 是主旨，queen、thousands of members 等细节全部支持这一句。方法是用删减法测试：把细节全部删去，看主旨句是否仍然概括全段；若仍然成立，主旨便找对了。易错之处是把细节当主旨，例如只记住 queen lays eggs 便以为是中心；主旨是笼罩全段的一句话，细节只是它的注脚，答题时宜先写主旨、后举细节，层次便分明。
- 自拟标题考点是用自拟标题检验理解。读完段落，试自己拟一个短标题，例如 Life in a Bee Colony；标题不用完整句，也不用句号，最好控制在五个词以内。这个练习能检查是否真正掌握主旨：拟得出，便是读懂了；拟不出，便要重读一遍。易错之处是标题写成完整句子，或太长太琐碎，反而暴露理解不清；多练数篇，概括能力自然提升，答主旨题也越来越有把握，这是阅读力的自我检测。
5例题示范 Example
问题：怎样找出一段文章的主旨？按首句、尾句、小节与选项范围四个线索逐步确定。
- 第一步：读段首句 — Bees are amazing insects. 主旨多数在此，先假设它是中心句。
- 第二步：首句不明显就看段尾 — 尾句有时是总结，特别留意 in short 等提示词。
- 第三步：分清主旨与小节 — queen bee 产卵、thousands of members 各有职责，都是支持的小节。
- 第四步：删去太窄的选项 — 只讲 queen 的选项只覆盖小节，不是全段主旨。
- 第五步：用自己的说法概括 — Bees live and work together like one big family.
- 答案：示范答案：主旨是 Bees live and work together like one big family. 小节（queen bee 产卵、thousands of members 各有职责）全部支持这句。掌握方法：先读首尾句，再分清小节，最后用一句概括。
