1、第一节基础写作第一讲句子成分的准确定位句子由各个组成部分构成，这些组成部分叫作句子的成分。句子的成分可分为主语、谓语、表语、宾语、定语、状语、补语等。弄清句子成分有利于在短文写作中写出正确的句子，有利于在完成句子题型中对考点的判断，有利于在阅读中对长句的理解。一、主语主语是句子的主体，是句子所要说明的人或事物，表示句子描述的是谁或什么。主语通常由名词、代词、数词、名词化的形容词、动词不定式、动名词或从句等充当。I was, nevertheless, talked into going on another funfilled holiday in the wilderness.尽管如此，我还
2、是被说服参加了另一个充满趣味的野外假期。(代词I作主语)It is important to speak English fluently.流畅地说英语很重要。(不定式作主语，it为形式主语)注意从句、不定式或动名词作主语时，为避免头重脚轻，往往用形式主语it来替代。二、谓语英语中动词一共分为四类：实义动词、连系动词、情态动词和助动词，实义动词又分为及物动词和不及物动词。实义动词可以单独作谓语，其他种类的动词都不能单独作谓语，连系动词需要和表语构成谓语；情态动词和助动词需要和实义动词或连系动词一起构成谓语。The earthquake happened in 2018.地震发生在2018年。(

4、形容词作表语)All the people are in high spirits.所有的人都情绪高涨。(介词短语作表语)He is the president of this company.他是这个公司的董事长。(名词作表语)四、宾语1宾语在句中主要充当动作的承受者，因此一般置于及物动词后，但不少介词与动词已构成固定的动词短语，所以介词的宾语亦变为动词短语的宾语。可以用作宾语的有：名词、代词、数词、名词化的形容词、副词、不定式、动名词、名词化的分词、介词短语、从句等。He admitted stealing the gold watch.他承认偷了金表。(动名词作宾语)What Im ho

6、passed a_booktome.)直接宾语间接宾语My friend bought me a dictionary as my gift.我的朋友给我买了本词典作为礼物。五、定语定语是用来说明名词或代词的品质与特征的词或一组词。可以用作定语的有：形容词、名词、代词、数词、副词、不定式、动名词、分词、介词短语和从句等。There are 50 women doctors in this hospital.这家医院有50个女医生。(名词作定语)Because my left foot was injured，I cant go with you as planned.因为我的左脚受伤了，我就不
