7．
A 90-year-old tortoise （乌龟） is going twice its usual speed after being equipped （装备） with a set of wheels．The animal，called Mrs T，was facing a terrible future after losing her two front legs in a mouse attack while she was sleeping in winter，but her owners glued the wheels onto her shell （外壳）．
"She's going double the speed she used to，"said the owner Jude Ryder，"She uses her back legs to push herself along and seems quite happy．"The 58-year-old owner was surprised when she went to check on her loved pet last month and found her front legs had been eaten in the mouse attack．The local animal doctor tried his best to save Mrs T．But he was afraid that the tortoise would not survive without being mobile．After paying£1，000for the treatment，Mrs Ryder turned to her son Dale for help．Dale designed the front wheels and used resin （树脂） to add them to the front of the shell．Mrs Ryder said："She liked them immediately，but she must learn how to turn and stop．She can get a good speed up，much faster than before．Mrs T is still quite young for a tortoise．She could go on for another 50years．All she needs is a new set of tyres （轮胎） sometimes．"
When Mrs T was sixty years old，she was bought as a pet for Dale，an 8-year-old boy．It liked running happily in Mrs Ryder's garden in spring and summer．When winter came，Mrs T slept in the garden shelter．A mouse got in last month and chewed （咬） off both her front legs．Mrs Ryder said："We were afraid she would be sure to die，but her new set of wheels have saved her life．She can run in the garden again and we can always find her because she leaves very strange footprints behind wherever she goes．"
Mice attacking tortoises is not uncommon around us-in 2013Britain's oldest tortoise died after a mouse attack．The tortoise called Thomas was 130when he was bitten at his home in Guernsey．He spent five days on strong antibiotics （抗生素），but the wound became so infected （被感染的） that his owner had no choice but to have him put to sleep．
