资源与建议
本文选自人教版必修5第一单元，讲述科学家Jhn Snw如何开展科学研究，找出了1854年伦敦霍乱的起源，控制住霍乱的进一步爆发。本文属于报告类体裁，具有很强的代表性，为后续同类文章的学习积累方法和经验，为阅读类似文章奠定基础。
本主题学习大致按照以下流程开展：看小视频引入话题→预测课文内容→细读文本了解细节→探究科学研究的步骤→运用科学研究步骤开展调查研究解决实际问题→归纳Jhn Snw优秀品质、感悟科学精神，为Jhn Snw写墓志铭。
本主题重点是基本阅读技能——预测、略读、细读等的训练。难点是如何利用科学研究的步骤，开展小组调查研究活动，解决实际问题。你可以通过任务1的完成来突破本节课的难点。

预习教材P91-92词汇；通过网络，初步了解Jhn Snw和chlera相关背景信息；复习Wmen f achievements 和Wrking the land两个单元中关于科学家贡献和品质的描述。
Step 1 Lead-in
Watch a vide clip f Sherlck Hlmes and d free talk.
Think abut these questins: Are yu a fan f Sherlck Hlmes? What d yu knw abut Sherlck Hlmes? What did Sherlck Hlmes d?

Jhn Snw defeats “king chlera”
Step 3 Reading
Activity 1: Read fr steps f carrying ut a scientific research
Read the text carefully, find the answers t the questins f each paragraph and match the steps f carrying ut a scientific research with each paragraph. Prepare t share yur answers（DO2）
Steps f carrying ut a scientific research (nt in the crrect rder):
Draw a cnclusin Think f a methd Cllect results/data Make a questin
Find a prblem Analyze the results/data Find supprting evidence
Activity 2: Read fr persnalities f Jhn Snw
Find the persnalities f Jhn Snw and try t describe him in a few sentences. （DO3）
Step 4 Pst reading
Task 1: Be a Hlmes and help find the “killer”

Pssible causes f dead fish:
= 1 \* GB3 ① water temperature = 2 \* GB3 ② lw disslved xygen in the water (低溶解氧) = 3 \* GB3 ③ pisn
(Which d yu believe is the cause f the prblem?)
Majr methds f scientific research:
= 1 \* GB3 ① Investigatin = 2 \* GB3 ② Experiment = 3 \* GB3 ③ Measurement = 4 \* GB3 \* MERGEFORMAT ④ Observatin
(Which methd/methds will yu use?)
The steps f hw yu will carry ut yur research
