Question

【題目】-- 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，我可以用一下你的電腦做作業(yè)嗎？——抱歉，我沒有電腦。
one，it，that辨析如下：
①one = a +上文出現(xiàn)的名詞，意思是“一個……”，比如：There are many bags.I want to buy one.= I want to buy a bag；
②it=the+上文出現(xiàn)的單數(shù)名詞（必需是單數(shù)名詞,包括可數(shù)名詞單數(shù)和不可數(shù)名詞），意思是“那個……”，I saw a dog on my way to school.It was big.it指上文的那條狗；
③that= the +上文出現(xiàn)的名詞（必需是單數(shù)名詞,包括可數(shù)名詞單數(shù)和不可數(shù)名詞），that不是用來指代上文的名詞,而是另外一個，例如：The weather in Nanjing is hotter than that in Beijing.that=the weather,但并非指上文的天氣,而是另外一個天氣。
此處意思是我沒有電腦（a computer），故選B。
