1 . Number sense is not the ability to count. It is the ability to recognize a _______, in number. Human beings are born with this ability. _________, experiments show that many animals are, too.

This means that the bird knows the _______ between two and three.

Another interesting experiment showed a bird's _______ number sense. A man was trying to take a photo of a crow(乌鸦)that had a nest in a tower, but the crow always left when she saw him coming. The bird did not _______ until the man left the tower. The man had an _______. He took another man with him to the tower. One man left and the other stayed, but they did not _______ the bird. The crow stayed away until the second man left, too. The experiment was ________with three men and then with four men. But the crow did not return to the nest until all the men were ________. It was not until five men went into the tower and only four left that they were ________ able to fool the crow.

2 . In a world with limited land, water and other natural resources, the harm from the traditional business model is on the rise. Actually, the past decades has seen more and more forests disappearing and globe becoming increasingly warm. People now realize that this unhealthy situation must be changed, and that we must be able to develop in sustainable (可持续的) ways. That means growth with low carbon or development of sustainable products. In other words, we should keep the earth healthy while using its supply of natural resources.

Today, sustainable development is a proper trend in many countries. According to a recent study, the global market for low-carbon energy will become three times bigger over the next decades. China, for example, has set its mind on leading that market, hoping to seize chances in the new round of the global energy revolution. It is now trying hard to make full use of wind and solar energy, and is spending a huge amount of money making electric cars and high-speed trains.

In addition, we are also seeing great growth in the global markets for sustainable products such as palm oil (棕榈油), which is produced without cutting down valuable rainforest. In recent years the markets for sustainable products have grown by more than 50%.

Governments can fully develop the potential of these new markets. First, they can set high targets for reducing carbon emissions (排放) and targets for saving and reusing energy. Besides, stronger arrangement of public resources like forests can also help to speed up the development.

Finally, governments can avoid the huge expenses that are taking us in the wrong direction, and redirecting some of those expenses can accelerate the change from traditional model to a sustainable one.

The major challenge of this century is to find ways to meet the needs of growing population within the limits if this single planet. That is no small task, but it offers abundant new chances for sustainable product industries.

1. The traditional business model is harmful because of all the following EXCEPT that____________.

A．it makes the world warmer

2. What can we infer from Paragraph 2?

A．China lacks wind and solar energy.

B．China is the leader of the low-carbon market.

C．High-speed trains are a low-carbon development.

D．Palm oil is made at the cost of valuable forests.

3. To full develop the low-carbon markets, government can____________.

A．cut public expenses

B．forbid carbon emission

C．develop public resources

D．encourage energy conservation

4. We can learn from the last paragraph that businesses have many chances to_____________.

A．develop sustainable products

B．explore new natural resources

C．make full use of natural resources

D．deal with the major challenge

5. What is the main purpose of the passage?

A．To introduce a new business model.

B．To compare two business models.

4 . 读写任务
阅读下面的短文，然后按照要求写一篇150词左右的英语短文。
       Jackie is perhaps the most easily annoyed koala (考拉) at the Featherdale Wildlife Park in southern Australia. All the koalas there are unhappy and complaining. You would be too if you were used to night activities and someone kept waking you up all day while you were trying to sleep it off. That’s right — sleep it off. The average koala is always half asleep because it feeds on the leaves of a special kind that makes it sleepy.
       The reason Jackie and her fellow koalas are repeatedly awoken from their deep sleep is so they can be hugged and photographed by tourists, who make the trips to Featherdale and an increasing number of other national parks for just that special experience. Whatever department in the Aussie government in charge of such things is now moving to make the practice illegal, which is understandable. How would you react, my friend, if you were trying to sleep off a dozen times and some round, furry creature smelling of grass kept waking you?
* 考拉即树袋熊
