two pounds of pork的be動詞

[pinkwinnie]

two pounds of pork的be動詞應該是is吧？
two litters of milk 或是two glasses of milk 呢?
區分的標準是什麼?

還有,可以說Do you have any plans on the weekend嗎?

[amigoblue]

two pounds of pork "are"

two glasses of milk "are"

依此類推,主詞是two pounds, two glasses...

Do you have any plans "for" the weekend?

考慮的是詞語搭配, plan for sometime or something

還不清楚的話請再提出來~~~

謝謝!
請問完全不能用on the weekend嗎?這樣說文法上是錯的嗎?

Whether a singular verb or a plural verb should be used for two pounds of pork or two glasses of milk depends on the sentence's singular or plural meaning.
e.g.
Two pounds of pork is what's needed for today's cooking.
Two glasses of milk every day is the key to his good health.

Two pounds of pork are stored in the freezer.
Two glasses of milk were served at the breakfast.

I think Glotynn's explanation sounds very reasonable. Therefore, we should choose "is" when we say "two pounds of pork is not too much for me." Is it right?
