    Unusual charity events such as these are a huge trend for raising money for worthwhile causes.If,however,you're looking to reall y like the idea of running through mud and freezing cold ice,then The Tough Mudder is perhaps what you've been searching for.In this difficult and tiring team event,participants finish a 10 to 12-mile barrier course that tests physical strength and mental courage.It's more about friendship than winning.Over 150 such events worldwide have raised£5 million.
    But fundraising doesn't have to involve physical effort.Students at a school in Illinois played Justin Bieber's song‘Baby'over loudspeakers and urged fellow students to pay to stop the song.They needed to raise $1,000 in one week to achieve this.Beyond expectations,they exceeded(超过) the goal within three days.Even teachers chipped in.
    If you want to join the ranks of gorillas next September,you only have to pay£60 to register.This includes the gorilla suit,which you can keep.If you take part,not only will you have been helping the gorillas and people who depend on their habitat,you'll never have to buy another set of fancy clothes again!

A few weeks passed.Then one day they heard horrible screaming from their back yard.They ran to the window to see what was happening.It took a while for them to believe their eyes.A lynx(猞猁)was on their back yard and it was just planning on grabbing their cat for lunch.The poor cat had no chance-it was screaming but had nowhere to run or hide.It would only be a matter of seconds and their cat would be dead.
And then the unimaginable happened.Out of nowhere a black lighting ran to the rescue.The little Labrador was only half grown but it attacked the lynx with all its might.It was barking on top of its lungs,ready to bite the other to bits.The lynx decided it was time to go and disappeared into the woods.
And ever since that day the cat's behavior toward the dog changed totally.Now it was the cat that followed the hero dog everywhere.
