Question

【題目】Sally ____ (do) her homework every day. But she ____ (not do) it last night.

Answer 1

【答案】does didn’t do

【解析】

句意：莎莉每天做家庭作業(yè)。但她昨晚沒做。由every day可知，上句是一般現(xiàn)在時(shí)，Sally 是第三人稱單數(shù)，謂語動(dòng)詞do用其三單形式does；由last night可知下句是一般過去時(shí)，謂語動(dòng)詞的否定形式要借didn't，后接動(dòng)詞原形。故答案為does；didn’t do。
