高中议论文写作提炼分论点之技法

写议论文,要围绕中心论点从不同侧面、不同层次上进行深入的议论。有了分论点,可使文章的层次更清楚,更有说服力。本文结合教学实际,就常用的分论点类型作了解说,以期对同学们的写作有一定的帮助。

例谈记叙文的布局谋篇方法

我们知道＂文似看山不喜平＂,因此在作文立意之后,就要注重布局谋篇的方法,力求突破常规思维,写出富有生活情趣的记叙文。【技法指导】首先是寻思接点开好头。作文的开头往往带有＂奠基性＂的作用,而记叙文的开头,不仅直接关系到行文的思路是否通畅,而且影响到全文格调的高下。因此,必须努力设计好既切题又新鲜的开头,能像张网一般,一下子将读者的心＂罩＂住。一般情况下用一两句话概述中心事件,或点明难忘的情景场面等。

突破说理瓶颈的两条路径

议论文的魅力不在“事趣”,而在“理趣”。“理直”才能“气壮”,“理透”才能“文斐”。但有些中学生在议论文写作中热衷于举例子、讲故事,而不去说理。有的虽然去说了,却不能把“理”说清楚,更不能说通透。怎样才能突破“说理”这一瓶颈呢?笔者以为,就中学生的认知水平而言,切近的路径有二。

“传统节日”PK“西方洋节”作文导写

在西方洋节与中国传统节日相互交融的今天,有的人坚持中国传统节日,而有的人却一心过着洋节,忘记中国的传统节日。

多维思辨 透析题意——“时评”类作文题审题指津

'时评'类作文题往往具有对象多、态度多、取向多、看法多等特点,让学生莫衷一是。我们只有展开多维思辨,综合考量,才能透彻而精准地审清题意。下面笔者以一则'时评'类作文题为例,对多维思辨的路径做一指津:【文题】阅读下面的材料,根据要求写作。

A controllable resistor and its applications in pole-zero tracking frequency compensation methods for LDOs

This paper presents a controllable resistor, which is formed by a MOS-resistor working in the deep triangle region and an auxiliary circuit. The auxiliary circuit can generate the gate-source voltage which is proportional to the output current of an low dropout regulator for the MOS-resistor. Thus, the equivalent output resistance of the MOS-resistor is inversely proportional to the output current, which is a suitable feature for pole-zero tracking frequency compensation methods. By switching the type of the MOS-resistor and current direction through the auxiliary circuit, the controllable resistor can be suitable for different applications. Three pole-zero tracking frequency compensation methods based on a single Miller capacitor with hulling resistor, unit-gain compensation cell and pseudo-ESR （equivalent serial resistor of load capacitor） power stage have been realized by this controllable resistor. Their advantages and limitations are discussed and verified by simulation results.
