1、时态:不同的时态相对应的助动词
一般现在时:谓语动词用原形(主语为第三人称单数时,动词加s或es,变否定句、疑问句时助动词为do或does)
一般过去时:谓语动词用过去式,变否定句、疑问句时助动词为did.
现在完成时:助动词have/has+动词的过去分词
过去完成时:助动词had+动词的过去分词
一般将来时:will/begoingto+动词原形
过去将来时:would/wasorweregoingto+动词原形
现在进行时:am/is/are+动词的现在分词
过去进行时:was/were+动词的现在分词
2、语态:主动语态变为被动语态的谓语结构
一般现在时:am/is/are+动词的过去分词
一般过去时:was/were+动词的过去分词
一般将来时:willbe+动词的过去分词
情态动词:can/may/must/need等情态动词+be++动词的过去分词
3、改反意疑问句时注意hardly,never,seldom,few,little,no等词表达的'是否定意义,变反意疑问句时用肯定形式。
4、在合并句子时,有些连词如notonly…butalso…,neither…nor…,either…or…是就近原则,连接两个主语时动词形式取决于与动词邻近的主语。而both…and…连接两个主语时,主语是复数。
5、简单句和复合句之间的互换常见的有:
带有疑问词的宾语从句改为特殊疑问词+to+动词原形的不定式;结果状语从句so…that…改为enoughto或too…to…的简单句。
6、保持原句意思改写句子时注意时态不变。
请根据下面提示,写一篇短文。词数不少于50。
In an English speech competition, you are asked to describe the following picture and explain to the judges how you understand it.
“开放”的命题方式是让考生根据一幅图画,在描述图画信息之余,发挥自己的.想象,展开简单的议论。
首先提醒同学:不要花太多时间挖掘图画深意!英语作文不看重你的思想厚度,而看重你的语言质量。开放作文有明显的套路可循。“开放作文”只要求你做两件事情,一件是描述图画(describe the following picture,另一件是阐述你对图画的看法(explain how you understand it。相应地,你只需要写两个段落,一段是“描述段”,另一段是“议论段”。
一般分三段:第一段用来描述图画内容。第二段用来写这幅图画说明了什么问题。第三段总结问题。
范文:
From the picture I can see a pair of proud compasses and a hard-working pencil. The compasses are big, drawing a circle with ease, while the pencil is small, drawing a line with great effort.
I think the compasses are reasonable to be proud because no one else can do the job better. At the same time, however, he should realize the pencil has his own advantages. The pencil can do other shapes better than the compasses, even pictures.
So in my opinion, while we are confident in ourselves, we should recognize strengths in others and show due respect for them.
