>請問這題要用are還是is?

應當用are.

beef是不可數名詞, 直接針對它要用There is,
但加上單位時, 就變成由那個單位來決定單複數了.

There is a pound of beef. <--- pound是單位, a表單數.
There is a lot of beef. <--- lot不是單位.
There are three lots of beef in the warehouse and five more on the way. <---這個lot(s)是單位.
There are two kilos of beef. <--- 您的句子

再多看幾個例句就更明白了:
There are five cups of water.
There are many kinds of furniture.
Ther are still several boxes of food.
