文體導(dǎo)讀

事理闡釋類說明文是一種以說明為主，闡明事理的概念、特點(diǎn)、演變、異同等的說明性文章。它著重于對(duì)客觀事物進(jìn)行介紹、解釋或分析，目的是幫助人們了解新的知識(shí)。此類文章通常以總分或總分總的結(jié)構(gòu)進(jìn)行闡述。它在寫作手法上采用舉例子、做比較、分類別、析因果、列數(shù)字、做詮釋、打比方、下定義、列圖表、引用、假設(shè)、對(duì)比或類比等說明方法。此類語(yǔ)篇涉及科技、社會(huì)和文化生活等多個(gè)領(lǐng)域。高考主要考查學(xué)生準(zhǔn)確把握文章主旨以及理解長(zhǎng)難句的能力。

策略導(dǎo)航

（1）巧用彩色筆細(xì)品文章。借助彩色筆對(duì)文本中的不同部分做標(biāo)注。例如，用紫色筆標(biāo)注開頭句，用綠色筆標(biāo)注段落的主題句，用紅色筆標(biāo)注說明闡述的方法，用黃色筆標(biāo)注邏輯關(guān)系詞，用藍(lán)色筆標(biāo)注長(zhǎng)難句，等等。寫作時(shí)，根據(jù)標(biāo)注的情況，進(jìn)行仿寫。

（2）利用“PRSR原則”構(gòu)建文本框架，搭建讀寫支架?！癙RSR原則”是事理闡釋類說明文采用的一種寫作視角，P為Phenomenon（現(xiàn)象），R為Reason（原因），S為Solution（措施），R為Result（結(jié)果），但有的文章并未完全涵蓋PRSR四種要素。在閱讀事理闡釋類說明文時(shí)，利用“PRSR原則”有助于我們梳理文章的篇章結(jié)構(gòu)和邏輯關(guān)系。在進(jìn)行事理闡釋類說明文寫作時(shí)，我們可以利用“PRSR原則”對(duì)文章進(jìn)行布局，同時(shí)還要使用正確的時(shí)態(tài)和人稱。

Keep a healthy weight

The key to keeping a healthy weight is regular exercise and good eating habits. Some?people think exercise and good eating habits require lots of effort or planning. But thats nottrue. In fact， the best way to work them into our lives is to make small changes.

Teens should get 60 minutes or more of physical activity a day. Note the word“activity”. As long as you’re getting your body moving， it doesn’t mean doing complicatedexercises or hitting the gym every day. All that matters is that each week you get the rightbalance of activities， including aerobics （有氧運(yùn)動(dòng)）， strength building， and flexibilityexercise. Make exercise a habit by arranging some time every day.

On days when you have soccer practice or an aerobics class， you may have no troubleexercising for an hour or more. But most of us are busy， and 60 minutes a day of exerciseseems like a lot of time. The good news is that it’s OK to divide it into shorter“exercisebreaks”throughout the day.

Just as you might have a healthy snack to stop yourself from getting hungry， exercisesnacks can keep energy levels high. So get up 15 minutes earlier and do some yoga or otherstretching activities. Fast walk or jog for 15 minutes at lunch. Do the same thing after school—or walk or bike home. Add to that climbing the stairs， taking gym class， and walkingbetween classes during the day， and you’ve probably reached your 60 minutes.

Eating well doesn’t mean dieting over and over again. In fact， studies have shown thatdieting often doesn’t work. The best way to keep a healthy weight is to make healthy foodchoices daily. For some of us， that means changing our mindset about food.

Use your creativity to come up with ways to fit exercise and healthy eating habits intoyour life in a way that works for you. We’re all different. Your best friend might prefer toschedule some gym time while you’d rather take your dog to the park. Knowing what’s rightfor you will make it a lot easier to do！
