Giving Cars a Second Life
Mention the word “recycling” and few of us think of cars, But in a world of limited space and resources, recycling everything — even cars — is very important.
Once a car reaches the end of its life, it is taken apart and any parts that can be reused are sold off. The remaining metal is melted down and sold while all the useless materials are just thrown away.
Usually, seventy-five percent of the car can be recycled．But new environmental rules in Europe say that at least eighty percent of old car parts must be recycled by 2006 and ninety-five percent by 2015.
To achieve this, someone has to find a way to recycle plastics, which are usually just thrown away. Fortunately. British scientists have come up with a solution. Through a new recycling process, they break down the plastics into gas, oil and a small amount of carbon (碳) and fibre. This is a big step forward for the car companies, who want to use more plastics to improve a car's efficiency (功率). Companies like BMW are also hoping to use more plastics that are easier to recycle.
1．Judging from the passage, the title “Giving cars a second life” means “_________”.
A．repairing the “dead” cars and setting them running away
B．using things from the “dead” cars to make new cars
C．making things from the “dead” cars useful again
D．making a car's life longer than expected
2．At present it is the least possible that _________ of an average car is made of plastic.
A．25% B．20% C．10% D．5%
3．The last sentence of the passage seems to suggest that________.
A．plastics are easy to recycle
B．plastics are easier to recycle than other materials
C．the plastics now used for cars are difficult to recycle
D．all kinds of plastics are equally difficult to recycle
4．According to the last paragraph the British scientists are trying to _________.
A．make new things of old plastics
B．make plastics change into new things
C．use old plastic parts for new cars
D．use more plastics to improve car's efficiency

1 ：less red meat and more fibre, less saturated fat(饱和脂肪)and more fruit and veg, right?Wrong, according to a controversial new book by nutritionist Zoe Harcombe．In the book, Harcombe charts her careful journey of research into studies that underpin(巩固)dietary advice－and her myth(误区)-breaking conclusions are surprising．
Myth： 2 ．
‘Real fat is not bad for us,’says Harcombe．‘It's man-made fats we should be demonising．’Why do we have this idea that meat is full of saturated fat?In a 100g pork chop, there is 2.3g of unsaturated fat and 1.5g of saturated fat．
Myth：We should eat more fibre．
For three decades, we have eaten fibre into our bodies to help us feel full and keep our digestive systems moving． 3 , says Harcombe．
The advice to eat more fibre is put forward along with the theory that we need to clean our digestive systems．But essential minerals are absorbed from food while it is in the intestines(肠道), so why do we want to wash everything out?Concentrate on not putting bad foods in．
Myth：You need to eat five portions of fruit and veg a day．
‘Five-a-day is the most well-known piece of nutritional advice,’says Harcombe．‘You'd think it was based on firm evidence of health benefit． 4 ’
‘Five-a-day started as a marketing campaign by 25 fruit and veg companies and the American National Cancer Institute in 1991．There was no evidence for any cancer benefit．’
Myth：Fruit and veg are the most nutritious things to eat．
Apparently not．Harcombe allows that vegetables are a great addition to the diet－if served in butter to deliver the fat-soluble(dissolved)vitamins they contain－but natural sugar, the fruit sugar in fruit, goes straight to the liver and is stored as fat．
5 , says Harcombe, who adds：‘Vitamins and minerals in animal foods－meat, fish, eggs and dairy products－beat those in fruit hands down．’
A．want to lose weight?Don't trust these．
B．We think we know what to eat．
C．This is not a good idea．
D．Fat is bad for us
E．Think again
F．We need take more exercise
G．Fruit is best avoided by those trying to lose weight
