①RecentlyJust可以用在动词之前，表示刚做过某件事，比如：Be careful— I just washed the floor, and it’s still wet.( I washed the floor a few minutes ago.)小心点，我刚刚才拖了地，还是湿的。He just finished a big project.(He finished the project very recently.)他刚刚才完成了一个大项目。②只，仅仅I thought you were hungry, but you ate just half of your sandwich.我以为你饿了，结果你只吃了半个三明治。2.OnlyOnly在大多数情况下可以和Just互换。Only two students came to class on the day before Christmas.= Just two students came…My kids only use the internet for schoolwork, not for playing games.= My kids just use…如果Just表示“刚刚”，它们就不能互换。注意在不同语境下的just：*--- Did you clean the whole house?--- No, I just washed the floor.(I only washed the floor.)*---Why is the floor wet?--- Because I just washed it.（不能用only替代）注意在不同位置中的just：I just ate two pieces of pizza.我刚吃了两块披萨。I ate just two pieces of pizza.我只吃了两块披萨。理解这个，你就能很好区分just和only的区别了。
