造句指懂得并使用字词,按照一定的句法规则造出字词通顺、意思完整、符合逻辑的句子。依据现代语文学科特征,可延伸为写段、作文的基础,是学生写好作文的基本功。造句来源清俞樾 《春在堂随笔》卷八:“其用意,其造句,均以纤巧胜。” 夏丏尊叶圣陶《文心雕龙》 四:“造句也共同斟酌,由 乐华 用铅笔记录下来。”

句子是语言运用的基本单位,它由词或词组构成,能表达一个完整的意思,如告诉别人一件事,提出一个问题,表示要求或制止,表示某种感慨。它的句尾应该用上句号、问号或感叹号。造句的方法一般有以下几种:

一、在分析并理解词义的基础上加以说明。如用“瞻仰”造句,可以这样造:“我站在广场上瞻仰烈士纪念碑。”因为“瞻仰”是怀着敬意抬头向上看。

二、用形容词造句,可以对人物的动作、神态或事物的形状进行具体的描写。如用“鸦雀无声”造句:“教室里鸦雀无声,再也没有人说笑嬉闹,再也没有人随意走动,甚至连大气都不敢出了。”这就把“鸦雀无声”写具体了。

三、有的形容词造句可以用一对反义词或用褒义词贬义词的组合来进行,强烈的对比能起到较好的表达作用。如用“光荣”造句:“讲卫生是光荣的,不讲卫生是可耻的。”用“光荣”与“可耻”作对比,强调了讲卫生是一种美德。

四、用比拟词造句,可以借助联想、想象使句子生动。如用“仿佛”造句:“今天冷极了,风刮在脸上仿佛刀割一样。”

五、用关联词造句,必须注意词语的合理搭配。比如用“尽管……可是……”造句:“尽管今天天气很糟,但是大家都没有迟到。” 这就需要在平时学习中,把关联词的几种类型分清并记住。

六、先把要造句的词扩展成词组,然后再把句子补充完整。如用“增添”造句,可以先把“增添”组成“增添设备”、“增添信心”或“增添力量”,然后再造句就方便多了。

随着信息新媒体的发展,网络已经成为继报纸、收音机、电视之后的主流媒体,并有将其整合的趋势。网民数量的激增使得网络话题的热议和网络语言迅速成为流行语。出现了很多新现象:网络造句——当某一新闻事件在网络迅速流传之后,新闻事件中的某一具有代表性的词语,在网友们的推广下,成为造句的主体,并迅速在网络流行展开。比如李刚事件中,我爸叫李刚成为流行语,以它进行的造句活动在网络铺开。例如:窗前明月光,我爸是李刚;给我一个李刚,我能撑起整个地球等。而在360与腾讯的3Q网络大战之后,一句“我很艰难的做出决定”也迅速流行。这类造句的特征主要是将已有的诗句、文章等进行改变而成。
