Question

【题目】-- Ross, can I use your computer to do my homework?
-- Sorry, I don't have _______.
A.it
B.one
C.this
D.that

Answer 1

【答案】B
【解析】句意：——Ross，我可以用一下你的电脑做作业吗？——抱歉，我没有电脑。
one，it，that辨析如下：
①one = a +上文出现的名词，意思是“一个……”，比如：There are many bags.I want to buy one.= I want to buy a bag；
②it=the+上文出现的单数名词（必需是单数名词,包括可数名词单数和不可数名词），意思是“那个……”，I saw a dog on my way to school.It was big.it指上文的那条狗；
③that= the +上文出现的名词（必需是单数名词,包括可数名词单数和不可数名词），that不是用来指代上文的名词,而是另外一个，例如：The weather in Nanjing is hotter than that in Beijing.that=the weather,但并非指上文的天气,而是另外一个天气。
此处意思是我没有电脑（a computer），故选B。
