Carrots are easy to grow and easy to harvest. They taste good. And they contain a lot of carotene( 胡蘿卜素).

When people think of carrots, they usually say it's a vegetable that is long, thin and orange. But carrots come in many different sizes and shapes. And not all carrots are orange. For example, Paris Market carrots are about five centimetres around. Belgian White carrots are, as their names suggest, white.

For the best results, carrots should be grown in sandy soil that does not hold water for a long time. The soil also should have no rocks. To prepare your garden for carrots, dig up the soil, loosen it and turn it over. Then, mix in some plant material. Weather, soil conditions and age will affect the way carrots taste. Experts say warm days, cool nights and a medium soil temperature are the best conditions for growing carrots that taste great.

Carrots need time to develop their full sugar content. This gives them their taste. The best way to judge if a carrot is ready to be harvested is by its color. Usually, the brighter the colour, the better the taste.

If the ground does freeze in your part of the world, simply cover your carrot garden with a thick layer(層) of leaves or straw. This will prevent the ground from freezing. You can remove the ground cover and harvest the carrots as they are needed.

Carrots are one of the world's most popular vegetables. They can be cooked and prepared in many different ways.

In science, people copy ideas from nature to solve problems or to create products. This is called biomimiery(仿生學(xué)). Its influence can be seen in many everyday products.

Nearly ten years ago, swimwear was influenced by nature. The Speedo Fastskin, a swimsuit, was seen at the Beijing Olympics and worn by 28 of the 33 gold medal winners. The technology is based on the rough patterns on a shark's skin, which allows the shark to swim faster.

Protecting astronauts' eyes from the sun's rays is very important but protecting their eyes from other dangerous radiation is also necessary. Scientists studied how eagles clearly recognize the animals they want to eat. They discovered that eagles have yellow oil in their eyes which fihers(過濾) out harmful radiation and allows them to see very clearly. They copied this oil and it is now used by astronauts and pilots in Eagle Eyes glasses. Besides protecting eyes from all the dangerous rays, these sunglasses also improve seeing in different weather conditions such as fog, sunlight or just normal light.

In another development, a car company has developed a new car which is based on the shape of the boxfish. Engineers chose to copy the boxfish skeleton(骨架) to make their Bionic Car because of its strength and low weight. Tile boxfish's bony body protects the animal's insides from injury in the same way as a car needs to protect the people inside it. This shape also means the car has less air resistance and so uses less fuel.

1.How many biomimicry products are mentioned in this passage?

_____________________________________________

2.What does the shark's skin allow a shark to do?

_____________________________________________

3.What special feature(特征) of eagle eyes was copied to make sunglasses?

_____________________________________________

4.What two features of a boxfish skeleton make it good for engineers to copy?

_____________________________________________

5.Do you think biomimicry will be more common in the future? Why or why not?
