a lot of ＝ lots of第一个lot前是要有a的用法上 这俩相等 都可以用在 可数不可数名词前而且注意 由a lot of 或者lots of 修饰的名词 所跟孝亩的动词单复数是跟那个名词有燃慎余关 而不是根据a lot of 或者lots of比如There are a lot of cars in the garage.There are lots of cars in the garage.There is a lot of milk in the bucket.There is lots of milk in the bucket.A lot of people are going to the show.Lots of people are going to the show.A lot of energy was dissipated.Lots of energy was dissipated.另外注意 a lot of / lots of这个皮滚说法是非正式用法 书面最好用 plenty of, much, a large number of之类的
