Mr. Smith had neither wife nor children. He liked nothing but drinking. He almost spent all of his money with drinks. Sometimes he went hungry, but he had to borrow some money to buy some food. One evening he met a friend of him in the street. The man invited him to have dinner in a restaurant. He was very happy that he drank too much. His friend stopped a taxi and ask the driver to take him home. Soon they reached in the door of his house. The driver drove away. But Mr. Smith couldn't insert the key into the keyhole. Just then a policeman went up, offering to help him but he refused, saying “The house is circled now. If you can keep it moving, I can open the door.”had后面加a
网友回答
(答案→)had后面加a
解析：文章介绍斯密斯先生没有家庭就喜欢喝酒，一次向朋友借钱，朋友请他喝酒却喝多了，引起的一个笑话。
【小题1】had后面加a，wife是可数名词，单数加a，句意：斯密斯先生既没有妻子也没有孩子。
【小题2】with改成on，词组：spend …on sth…，把…花在…上
【小题3】but改成and/so，有时他很饿，只好借钱去买食物。这两句话是并列或是因果关系
【小题4】 him改成his ，a friend of his是双重所有格
【小题5】 very改成so，句意：他是如此高兴以至于喝多了。
【小题6】 ask 改成asked，和stopped并列用asked
【小题7】去掉 in ，reach是及物动词，到达他家门口
【小题8】went改成came，这时，一个警察过来了。
【小题9】 circled改成 circling，房子在转圈。The house和circle是主动
【小题10】keep 改成stop (或it 后加from)，从句意看：斯密斯先生说：如果你能阻止它动，我就可以打开门。Keep sb from doing和stop sb （from） doing都是阻止某人做…
