Chocolate which hepls you lose weight by actually burning calories as you eat it ? It sounds wonderful.

But unfortunately , for anyone who spent £ 37 on a 40-day supply of Slim Choc, the idea is nothing more than daydream.

The product was one of a lot of “miracle cures” marketed to Britons which had no evidence to back up their grandiose(夸大的) claims, according to the Office of Fair Trading.

The OFT said that such tricks affect 200,000 of us a year, at a cost £ 20 million . Some 78 per cent of the victims(受害人)are female, but a large number of men are also taken in by “cures”for hair loss.

OFT Director of Consumer Protection Mike Haley said,“Miracle health tricks target people who are eager to lose weight or find a cure. The products are often worthless and can even be dangerous with untested and possibly harmful ingredients(成分)。”

The OFT yesterday warned consumers about the adverts for Slim-Choc, which were contained in junk mail sent to thousands of homes acorss Britain.

The company chaimed that eating the “slimming chocolate”could help users lose 20lbs in just 20 days, without exercising or cutting back on food.

The tricks claimed this was a “brand new revolutionary cure for the overweight”,and it was “the first and only cholcolate that burns off fat”. Thousands were persuaded to pay £ 37 for a 40-day supply.

Alice Tuff, of the Sense About Science charity, said :“The emotional and financial costs for the people who get drawn in can be huge and it is very important that we keep promoting public vigilance(警惕)in dealing with this serious problem.”

1.Which of the following would be the best title for the passage?

2.Which of the following best states Mike’s idea?

A.The emotional and financial costs for victims can be great

B.Eating the “slimming chocolate” could help users lose weight.

A.turn to normal in 40 days,   B.loss weight without exercising
