“Track!” said my master.

Like any good tracker-dog who has received the command（命令） he most loves, I gave a bark of excitement, put my nose down to the ground and sniffed. The ground was rich with smells. Even in the high-class housing area where we were working, the stones held traces of many sole and confusing scents （smells）. As I searched for the scent that would give me a clue to the tail of the guilty man, my tail wagged slowly, thoughtfully, delightedly. Work was like play to me； I enjoyed it.

A small group of people gathered behind us. Among these onlookers was the old caretaker of the building next door to ours. He spoke in a scornful voice, “You actually think your dog might catch a thief three days after the event?” My master said nothing, but I'm sure he must have smiled. I did not turn to look. I knew he would not speak unless it was to give me a new command.

I needed to concentrate. My task was difficult. I had to pick out one scent among the many that lay about and then tracked it to its source.

“You're wasting your time,” said the caretaker. I looked at him without raising my head. He was running his hand over his fat stomach. His rough palm and smooth shirt combined to make a slight noise. It was part of my training to be aware—often it is only a little whisper of a noise that alerts（提醒）you to be drawing of a weapon. But of course the aging caretaker was going to do no such thing. There was no smell of fear or nervousness about him. He was merely being clever and talkative.

“I've seen many tracker-dogs in my time,” said the caretaker to the onlookers. I served with the police years ago. We would never have thought of using a tracker-dog to find a car thief. Impossible. Everyone knows that dogs are useless in such matters.

In a sense he was right. I'm sure there's no need to tell you that, just as a dog's hearing is much better than a human being's, so his sense of smell tells one thing from another far better than a great detective. If Sherlock Holmes could work out that a man had had an egg for breakfast by seeing the yellow stain on his mouth, a trained dog could tell you whether the hen that laid the egg was healthy or not.

I know it sounds funny and I mean it to be. But I'm not exaggerating. A dog can tell you—if you understand a dog’s way of communicating—all this and more without even setting eyes on the man he is investigating.

1.Who do you think the dog was tracking?

A．The thief. B．The caretaker.

C．The master. D．The onlookers.

2.How did the dog react to the command to track?

A．It thought for a while and did what was asked.

B．It was happy, even though it wasn't trained for the task.

C．It was angry because there were so many smells.

D．It was excited because it took pleasure in tracking.

3.In the dog's opinion, its sense of smell ________.

A．can give us fewer details about what a human has already discovered

B．can achieve more than what a human's only if the smell is not hidden

C．is particularly trained to pick out one scent among hundreds

D．is better than its sense of hearing when it does tracking

4.According to the passage, the dog is ________.

A．honest and hopeful B．smart and helpful

C．kind and careful D．popular and thoughtful

As we become richer and richer, we are producing more and more rubbish. The Asian Development Bank（ADB） says that our largest cities produce 760 000 tons of solid waste every day. It predicts（预料） that there will be an increase—to 1.8 million tons—by 2025. It seems too much to deal with. “The growing waste is simply trying to cover our cities,” says Michael Lindfield, a specialist of ADB in Manila.

The proper treatment of rubbish is beyond the financial resources（金融资源）of many countries. The World Bank says some governments are spending as much as half of their budgets（预算） dealing with rubbish. And even so, it is common that half of all the waste goes uncollected.

Much of the added difficulty is packaging from consumer（消费者）products and the products themselves—all of which need years, even centuries to decompose（化解）. Lindfield believes that four of every five products we buy are thrown away after a single use. It all makes the work to deal with solid waste much more expensive.

The rubbish is more than just an environmental problem—it also influences national economies（经济） by disturbing the world market, discouraging tourism and slowing down industrial development.

Lots of rubbish also influences the look of our cities. As he walks to work from his home in Bangkok every day, Chatchat Mutita, a 36-year-old advertising specialist, must pass a lot of ugly, smelly rubbish that isn’t collected until late at night. He says things get worse when it rains because some yellow water will stream from the rubbish to the sidewalk.

Modern technology can make the problems of open dumps less serious. But Chettiyappan Visvanathan, a professor at the Asian Institute of Technology in Pathumthal, Thailand, believes that there are no engineered facilities（设备） in nine of every ten dumps all over the country. Some countries depend on most solid waste to produce energy, but there’s a growing problem of air pollution. Burning is far more dangerous than open dumps. The ADB says the growing rubbish must be dealt with by the “3Rs” —reducing the waste, reusing things that are being thrown away and recycling materials.

Planet Earth Welcome to Planet Earth Museum, a museum where you can learn some interesting facts about the world we live in. “1.. Who knows, maybe you’ll see them all one day! Where shall we go first, children? “Forests!”

Forests are home to over half of the world’s animals and plants. Trees clean the air and produce oxygen (O2) for us to breathe. Every day we throw away hundreds of trees in paper and card and we destroy more than 36 football fields of forests.

2.. They transfer (传递) the sun’s heat into the air and move it around the world. A lot of the rubbish we produce on land pollutes the oceans. Turtles mistake plastic bags for jellyfish and die when they eat them.

At opposite ends of the world, the Arctic and Antarctic are freezing cold lands. 3.. The fuel we use for energy makes the earth warmer. As it gets warmer, the ice melts (融化) and the sea rises. The land disappears.

Rivers collect rain water and carry it to the oceans. 4., so it is safe for us to drink. Farms and factories pollute the rivers with pesticides (杀虫剂) and chemicals. Every day we flush (冲掉) 50L of dirty water down the toilet.

This is a green world, where people respect nature and live a long and healthy life. Wouldn’t you like to live here?

A. It is so cold that the sea it covered in ice

B. There are many amazing places on Earth

C. Thanks a lot for your visit to our museum

D. Along the way, plants take in and clean the water

E. The oceans are home to millions of sea animals
