lots of；a large number of ；a large amount of ；a great quantity of；plenty of等。

翻译：许多的。解析：a lot of意为"许多的",既可以修饰可数名词又可以修饰不可数名词。所以它的同义词组有意为“许多”，表示量很大，但是没必要指明量的多少，多用在比较不正式的谈话或是写作中（正式的用mang或much），后面跟可数名词和不可数名词，谓语的单复数根据后面接的名词来变化，例如：可数名词：A lot of people went to the game.很多人去看了比赛。Lots of people went to the game.很多人去看比赛。A lot of computers are needed at schools.---->computers为复数，谓语用复数学校需要很多电脑。Lots of computers are needed at schools.学校需要很多电脑。不可数名词：A lot of snow falls in winter.---->snow为不可数名词，谓语用单数冬天下了很多雪。Lots of snow falls in winter.冬天下了很多雪。A lot of water is wasted.很多水被浪费了。Lots of water is wasted.大量的水被浪费了。一般情况下，lots of和a lot of可以通用，相比于a lot of，lots of更为不正式二、a lot当作副词，意为“经常，很多”，例如：I like basketball a lot.我非常喜欢篮球。She's a lot happier now than she was.她现在比以前快乐多了。I don't go there a lot anymore.我不再经常去那里了。Mum and I used to fall out a lot.我和妈妈过去经常争吵。

三、为避免句子冗长，通常把lots of简写为lots，相当于plenty，例如：She didn’t bring anything to eat but we’ve got lots anyway.=She didn’t bring anything to eat but we’ve got lots of sth(sth edible)anyway.她没带吃的，但我们还有很多。A:I haven’t got any money.A：我没有钱。B:Don’t worry,I’ve got plenty.(plenty of money)B：别担心，我有很多。（很多钱）
