请将下列句子改为否定句,每空一词(含缩写)。 1. Li Ming receives an e-mail. Li Ming an e-mail.2. My English will become very good. My Englishvery good. 3. H-七年级英语
5.现在进行时带always,often,usually,sometimes,等频率副词表感情色彩,一般现在时则没有此用法。
一般现在时的句子转换:
(1)当句子中有be动词或情态动词时,则把be动词或情态动词(can,could等等)提到主语的前面变成疑问句;在be动词或情态动词后面加not变成否定句.
例:
①陈述句:She is a student.
疑问句→ Is she a student?
否定句→ She is not a student.
②陈述句:I can swim.
疑问句→ Can you swim
否定句→ I can not swim.
(2)当句子中即没有be动词,也没有情态动词时,则在主语前加助动词do (you,以及复数),does(单数she,he,it)变成问句;
在主语后谓语动词前加助动词don’t(I,you,以及复数), doesn’t(单数she,he,it)变成否定句,助动词后的动词要变成动词原形。
例:
①陈述句:We get up at 7:00 every morning.
疑问句→Do you get up at 7:00 every morning?
否定句→We don’t get up at 7:00 every morning.
②陈述句:She has a little brother.
疑问句→ Does she have a little brother?
否定句→ She doesn’t have a little brother.
一般现在时的表达方法:
主要通过谓语动词的变化和用时间词语来表示,其中最主要的是谓语动词的变化。现在一般时动词变化的规则是:
1.如果主语是名词复数和第一人称I、 we ,谓语动词不用做任何变化,即仍然用动词原形表示:
We usually go to school at 7:30. 我们通常7:30上学去。[go]
My parents give ten yuan to my sister every week.我父母每星期给我妹妹十元钱。[give]
2.主语是任何一个单数名词或者是第三人称单数,谓语动词要进行必要的变化。特别提一点:不可数名词也算作单数处理。
3.谓语动词的变化规律是:
