Passage 39

(07·北京B篇)

The Book Of Life

So far,scientists have named about 1.8 million living species(物种),and that’s just a small number of what probably exists on Earth.With so many plants,animal,and other living things covering the planet,it can be tough to figure out what type of grass is growing by the roadside or what kind of bird just flew by.

A soon-to-be-started Web site might help.An international team of researchers has announced the creation of Web-based Encyclopedia(百科全书) of Life (EoL).The project aims to list every species on Earth in a single,easy-to-use reference guide.

To get the encyclopedia started,the creators will use information from scientific databases(数据库)that already exist.And eventually,in special sections of the site,non-scientists with specialized knowledge will come to helf.Bird-watchers,for example, will be able to input what birds they’ve seen and where. To make sure the encyclopedia is accurate, scientists will review much of the information added to it.

As the EoL develops,you might find it useful for school. Projects,The site will feature   (以。。。。。。为特色) special pages for kids who are studying ecosystems in their neighborhoods.Another convenient feature of the EoL is that you’ll be able to pick the level of detail you want to see to match your interests,age,and knowledgs.

It now takes years for scientists to collect all the data they need to describes and analyze species.The creators of the Encyclopedia of Life hope that their new fool will speed up that process.

Passage 38

(07·宁夏、海南、全国ⅠB篇)

Many animals recognize their food because they see it. So do humans. When you see an apple or a piece of chocolate you know that these are things you can eat. You can also use other senses when you choose your food. You may like it because it smells good or because it tastes good. You may dislike some types of food because they do not look, smell or taste very nice. Different animals use different senses to find and choose their food. A few animals depend on only one of their senses, while most animals use more than one sense.

Although there are many different types of food, some animals spend their lives eating only one type. The giant panda(大熊猫)eats only one particular type of bamboo(竹子). Other animals eat only one type of food even when given the choice. A kind of white butterfly(蝴蝶)will stay on the leaves of a cabbage, even though there are plenty of other vegetables in the garden. However, most animals have a more varied diet(多样化饮食). The bear eats fruits and fish. The fox eats small animals, birds and fruits. The diet of these animals will be different depending on the season.

Humans have a very varied diet. We often eat food because we like it and not because it is good for us. In countries such as France and Britain, people eat foods with too much sugar. This makes them overweight, which is bad for their health. Eating too much red meat and animal products, such as butter, can also be bad for the health. Choosing the right food, therefore, has become an area of study in modern life.

Passage 37

(07·山东D篇)

Sports shoes that out whether their owner has enough exercise to warrant time in front of the

television have been devised in the UK.

The shoes - named Square Eyes - contain an electronic pressure sensor and a tiny

computer chip to record how many steps the wearer has taken in a day. A wireless transmitter

passes the information to a receiver connected to a television, and this decides how much evening

viewing time the wearer deserves, based on the day’s efforts.

The design was inspired by a desire to fight against the rapidly ballooning waistlines among

British teenagers, says Gillian Swan, who developed Square Eyes as a final year design project at

Brunel University to London, UK. “We looked at current issues and childhood overweight really

stood out,” she says. “And I wanted to tackle that with my design.”

Once a child has used up their daily allowance gained through exercise, the television

automatically switches off. And further time in front of the TV can only be earned through more

steps.

Swan calculated how exercise should translate to television time using the recommended daily amounts of both. Health experts suggest that a child take 12,000 steps each day and watch no more than two hours of television. So, every 100 steps recorded by the Square Eyes shoes equals

precisely one minute of TV time.

Existing pedometers (计步器) normally clip onto a belt or slip into a pocket and keep count of steps by measuring sudden movement. Swan says these can be easily tricked into recording steps through shaking. But her shoe has been built to be harder for lazy teenagers to cheat. “It is possible, but it would be a lot of effort,” she says. “That was one of my main design considerations.”
