在英文中,如果你想表达字典又大又沉,你可以使用以下表达:

"It's a massive, heavy dictionary."
"This dictionary is huge and weighs a ton."

这个表达的来源可能来自于字典的外观和实际重量。字典通常都很厚,有很多的页面,所以它们可能会很厚很重。

下面是一些例句:

"I can't even pft this dictionary. It's so heavy!" (我甚至没法举起这本字典,它太沉了!)
"I need a smaller dictionary. This one is too big and heavy to carry around." (我需要一本更小的字典。这本太大太沉了,搬不动。)
"I'm surprised this dictionary fits in my backpack. It's so massive." (我很惊讶这本字典能装进我的背包里。它太大了。)
