　　　 Britain is facing a sharp rise in its rat population as growing numbers of people leave fast food scraps in the street ,an environment group warned .Keep Britain Tidy said the rodents(啮齿动物)were stopping their traditional hunts underground and were roaming the streets ,tempted by discarded burgers ,pizzas and crisps. “The rat population is on the rise and soon it’ll be as common to see a rodent on our street as it is to see a dog or a cat,” said group Director ,Sue Nelson. The practice of dumping fast food litter and scraps on the street rather than in the trash-with young men the worst offenders-was behind the rise. According to the National Rodent Survey in 2005, Britain’s rat population has grown by nearly one quarter since 2000 and is now estimated at 60 million ,two million more than the human population. On average a rat can give birth every 24-28 days and just a single pair of rats can produce a colony of 2,000 a year. Around 200 people a year get Weil’s Disease –an infection which can lead to liver or kidney(肝肾)failure and eventually death and which is arrived in rat’s waste. To highlight the issue ,Keep Britain Tidy launched a cinema ad entitled “How close do you want them to get?” The ad gave a shocking image of a young woman sleeping in a bed of rots –echoing the nightmare scene from James Herbert’s classic horror tale The Rats, in which mutant rodents begin to prey on(捕食)humans.

　　　 But I wonder about my Momma sometimes, and all the other Negro(blacks )mothers who got up at 6 a.m. to go to the white man’s house with sacks over their shoes because it was so wet and cold. I wonder how they made it .They worked very hard for the man, they made his breakfast and they scrubbed his floors and they took care of his babies. They didn’t have too much time for us.

　　　 I wonder about my Momma ,who walked out of a white woman’s clean house at midnight and came back to her own where the lights had been out for three months ,and the pipes were frozen and the wind came in through the holes in the wall. She’d have to make deals with the rats: leave some food out for them so the wouldn’t bite the doors or the babies. The roaches(蟑螂)？Oh ,they were just like part of the family!

　　　 I wonder how she felt telling those white kids she took care of to brush their teeth after they ate, to wash their hands after they finish bathroom. She could never tell her own kids because there wasn’t soap or water back home.

　　　 I wonder how my Momma felt when we came home from school with a list of vitamins and pills the school nurse said we had to have .Momma would cry all night , and then go out and spend most of the rent money for pills. A week later ,the white man would come for his eighteen dollars’ rent and Momma would beg him to wait until tomorrow . She had to lie to him that she had lost her wallet or the relief check was coming soon or the white people had some money for her. Tomorrow I’d be hiding in the closet because there was only supposed to be two kids in the flat ,and I could hear the rent man shout at my Momma and call her a cheat. And when he finally went away, Momma put the sacks on her shoes and went off to the rich white man’s house to dress the rich white kids so their mother could take them to a special baby doctor.
