a lot 和a lot of和lots of用于肯定句?

lot 和a lot of和lots of用于肯定句?

lots of 和 a lot of的意思基本一样,没有什么区别,可以通用,都可以后接可数名词或不可数名词。不过书面语用a lot of较多,口语用lots of较多。
例句:
China does a lot of/ lots oftrade with many countries.
You have lots of/a lot of time to finish the work.

a lot of只用于陈述句吗?

不是的!a lot of 等同于 lots of,只能用在肯定句中。既可修饰可数复数名词,也可修饰不可数名词。表示“许多”的意思。a lot of既可接可数名词,也可接不可数名词,多用于肯定句。a lot oflots of, 可修饰可数或不可数名词,意为“许多”,“大量的”,相当于many或much。a lot, a lot of, lotsmany或much。
a lot of与lots of放在修饰的名词前。
There were a lot of people at the party.
有许多人参加聚会。

a lot of 和much在程度上有区别吗?

much 修饰不可数名词,much作主语时谓语动词用单数
a lot of修饰可数名词或者不可数名词
much 后接不可数名词,通常用在问句和否定句中,在肯定句中,有时候在正式场合使用,在a, an, the, this, that,my, your, him, them等词前用,加of 。用在否定句中,表达期望某物没有很多。可以用在形容词和副词比较级前,表达强烈的对比。
如:
How much time has we left他离开多久了
 Much of the time was spent on learning. 花许多时间在学习上。
  There hasnt been much good weather recently.最近都不是什么好天气
a lot of在肯定句中非正式场合使用。既可以用在可数名词复数,也可用在不可数名词前。用在否定句中,表达期望某物有很多。
如:
  We can see a lot of birds in the tree
