请按照analogy的论证结构,从下列几个比较情境中,任选一个,并进行论证分析。有的情境只有比较,没有形成论点,同学可以自己给出论点。 Life is like a race. The one who keeps running wins the race, and the one who stops to catch a breath loses. 2. Just as a sword is the weapon of a warrior, a pen is the weapon of a writer. 3. How a doctor diagnoses diseases is like how a detective investigates crimes. 4. Just as a caterpillar comes out of its cocoon, so we must come out of our comfort zone. 5. 如果有自己特别想要论证的题目,也可以自选题目,但是要有common interests.只涉及个人的话题不建议论证。
