将下列句子改成否定句

He had lessons last Friday.

上星期五他上课了
改为否定句就是，上星期五他没有上课
He had not lessons last Friday.[had 是 has/have的过去式】

拓展：
最常见的有：动词be的否定式 动词be根据不同的人称和时态可以有am,is,are,was,were等不同形式,可用作连系动词（表示“是”、“在”等）和助动词（用于构成进行时态和被动语态等）,但不管何种情况,构成否定式时,一律在其后加not：
例如：This is his English book .这是他的英语书
变为否定句为This is not his English book.这不是他的英语书.
如果谓语动词是实义动词,就在动词前面加助动词（do,does及其过去式did）再加not
He studies hard at his lessons.
变为否定句为：He doesn't study hard at his lessons.
在英语里不同类型的句子变为否定句的方法不同,不可套用规则的特殊情况还要平时注意积累.
一、当everyone(everybody).someone(somebody),something,everything等不定代词作肯定句的主语时,一般不能在其后加
not变为否定句,而要把不定代词everyone(everybody).someone(somebody)改为no one或no
body；把不定代词something,everything改为nothing等形式构成否定句.
二、both,all 作肯定句的主语或主语的定语时,变否定句时应把both改为neither,all改为none.
三、带有too,also的肯定句变为否定句时,应将too,also变为either,且放在句末；带有already的肯定句变为否定句时,应将already变为yet,且放在句末.
四、由think,believe,suppose等表示猜测的动词引起的宾语从句如果变为否定句,一般要否定主句谓语动词,我们称之为“否定转移”.
五、在有had better,would rather的肯定句变为否定句时,通常将其看作一个情态动词,其后直接加not.
六、肯定句中有and连接的两个或两个以上的并列成分,变为否定句时应把and改为or.
七、祈使句变为否定句时,一般在句首加Don't.以let开头的祈使句,在let后面加not,也可在let前加Don't,
八、have(has)在肯定句用作动词时,有两种情况,表示所有关系,直接在后面加not,也可在前面加助动词及not变否定句,表动作时,只能在前面加助动词及not变否定句.
九、含有both and的肯定句常用either nor来构成否定句.
十、含有always,often的肯定句变为否定句时,要把always改为never,把often改为seldom.
十一、含有a few,a little等的肯定句改为否定句时,将a few,a little改为few,little表示否定意义.
