    What is the number one favourite pet in the UK? If you think the answer is “dog” – you are wrong. There are 8.6 million cats and 8.3 million dogs in Britain according to recent figures. But experts predict (预测) that there will be more dogs than cats next year as dogs become more and more popular.

    Dogs as accessories (配饰)

    We like to spend time with our pets. The Queen is famous for her corgis (威尔士矮脚狗) and is often photographed with them. Nowadays some dog owners are more extreme(极端的) – a few TV celebrities even take their dogs shopping or to restaurants. Chihuahuas (吉娃娃犬) are especially popular as “handbag dogs” because they are so small.

    Dog holidays

    People are also giving their pets holidays. Many UK hotels and holiday parks now welcome dogs as guests. What about owners who go abroad? They can leave their pets at a dog hotel or dog spa while they are away. Some even provide their canine (犬) guests with a TV.

    Dogs are for life

    The British charity, Dogs Trust, finds homes for thousands of lost and homeless dogs every year. Their famous slogan(口号) “A dog is for life and not just for Christmas” was created in the 1970s to teach people about the responsibility(责任) of owning a dog. Dogs Trust told British people not to give dogs as gifts or treat them like toys.

    Dogs on TV

    Victoria Sitwell is the host(主持人) of the popular TV programme called “It's me or the dog”. In the show Victoria helps dog owners with their pets' bad behavior. She tries to find ways to problems such as a Dalmatian who thinks he owns the house and won't let the family sit on the sofa, dogs that will only eat ice cream and biscuits and even a bulldog(恶犬) who uses the owner's bed as a toilet. Yuck!

    Fashion for dogs

    You can shop online or on the high street for the latest in dog clothes and accessories(配件). Specialist shops sell dog boots, dog dress costumes, dog coats, dog dresses and dog pants.

阅读下面的文言文,完成小题。
         秦王使人谓安陵君曰:“寡人欲以五百里之地易安陵,安陵君其许寡人!”安陵君曰:“大王加惠,以大易小,甚善;虽然,受地于先王,愿终守之,弗敢易!”秦王不悦。安陵君因使唐雎使于秦。
         秦王谓唐雎曰:“寡人以五百里之地易安陵,安陵君不听寡人,何也?且秦灭韩亡魏,而君以五十里之地存者,以君为长者,故不错意也。今吾以十倍之地,请广于君,而君逆寡人者,轻寡人与?”唐雎对曰:“否,非若是也。安陵君受地于先王而守之,虽千里不敢易也,岂直五百里哉?”
         秦王怫然怒,谓唐雎曰:“公亦尝闻天子之怒乎?”唐雎对曰:“臣未尝闻也。”秦王曰:“天子之怒,伏尸百万,流血千里。”唐雎曰:“大王尝闻布衣之怒乎?”秦王曰:“布衣之怒,亦免冠徒跣,以头抢地耳。”唐雎曰:“此庸夫之怒也,非士之怒也。夫专诸之刺王僚也,彗星袭月;聂政之刺韩傀也,白虹贯日;要离之刺庆忌也,仓鹰击于殿上。此三子者,皆布衣之士也,怀怒未发,休祲降于天,与臣而将四矣。若士必怒,伏尸二人,流血五步,天下缟素,   今日是也。”挺剑而起。
         秦王色挠,长跪而谢之曰:“先生坐!何至于此!寡人谕矣:夫韩、魏灭亡,而安陵以五十里之地存者,徒以有先生也。”
