Our desks and chairs ________________ (make) of wood.The paper of books and newspapers ___________ (make) from wood答案我知道 请说明理由 O(∩_∩)O谢谢

Answer 1

are made
is made

make of与make from两者都常用在被动语态中,表示“某物由.构成的”. make of 的原材料是看的到的,即平常我们说的物理现象,比如The chair is made of wood.椅子是有木头做成的.make from的原材料是看不到的,比如Paper is made from the trees. 纸张是由木材做成的.是一种化学变化,从纸上是看不出一棵树滴.
然后就是注意单数、复数就行了

追问

为什么第一个是are 第二个是is

追答

第二个主语是the paper

追问

是The paper of books and newspapers

追答

书和报纸的纸，书、报纸只是修饰纸的，不能算主语。主语就是the paper，所以用is

Answer 2

Desks and Chairs are made of wood.

The paper is made of wood

看主语啊。。。把修辞词都去掉，就是上文。就很显而易见了。。。PAPER不可数名词，用单数形式
