He had left his pregnant(怀孕的) wife and his two children 19 at the car and said that he would hitchhike(搭便车) back.Once I had 20 a can with petrol, I took him back to his car where his two-year-old and four-year-old children were both 21 , saying that they were cold. Once the car had started, I suggested that he 22 me back.Before leaving, I had turned the heater 23 in the roadhouse, so that when we went in, it was nice and 24 .While the little ones played and ran 25 ,I prepared bread and butter for the children, and hot chocolate for the 26 .It was about 5 a.m. before they 27 .The young fellow asked me how much he 28 me and I told him that the petrol pump (加油泵) had 29 $15.He offered to pay “call-out fee”, but I wouldn’t accept it.About a month later, I received a 30 from Interstate, a large bus company that we had been trying to31 to stop off at our roadhouse for a long time.

All goldfish bowls are no longer allowed and dog owners must walk their dogs.This comes after a national law was passed to give prison sentences to people who desert cats or dogs.“The civilization of a city can be measured by this,” said Monica Carina, the councilor (议员) behind the new law.“It’s good to do whatever we can for our animals who in exchange for a little love fill our existence with their attention,” she told a Rome newspaper.The newspaper reported that round bowls don’t give enough oxygen for fish and may make th em go blind.“Rome has tried to protect fish more than anywhere else in the world .It stands out for recognizing that fish are interesting animals who deserve（值得）over respect and compassion every bit as much as dogs and cats and other animals,” said Karin Robertson, a director of the People for the Ethical Treatment of Animals.Last year a law was passed in Italy that gives people who desert pets big fines （罚款）and prison sentences. Since then local governments have added their own animal protection rules.The northern city of Turin passed a law in April to give pet owners fines of up to ＄598 if they do not walk their dogs three times a day.The new law in Rome also says that owners mustn’t leave their dogs in hot cars or cut their dogs’ tails to make them l ook lovelies. The law also gives legal recognition to the “cat ladies” who feed homeless cats. The cats live all over the city from ancient ruins to modern office car parks.36. The new law passed in Rome will _____A. help improve fishing environmentB.guarantee better conditions for goldfishC.stop people from catching goldfishD.discourage keeping goldfish at home38. The underlined word “compassion” in Paragraph 6 is the closest in meaning to ____A. pityB.praiseC.supportD.popularity39. People may break the law in Turin if they _____A. keep their dogs or cats in carsB.feed homeless animals in car parksC.raise their cats near ancient ruinsD.shut their dogs home all day long四．用所给词的适当形式填空。
