The German shepherd runs off and noses around in the grass of Kenya’s Laikipia Plateau． “OK, Oakley,” the dog’s handler orders, “Find it!”

Oakley sniffs （嗅） until he comes to a bush, then stops, sits, and looks up at his handler． She bends to see what he has found: the waste of an endangered African wild dog． “Good dog!” she praises． The handler pulls a tennis ball from her pocket． Oakley jumps for his reward．

“He doesn’t actually want the waste,” says Aimee Hurt, a founding member of the U．S．-based group Working Dogs for Conservation． Hurt is in Kenya to train both Oakley and his handler． “He finds it so he can play with his ball． We’re the ones who want the waste．”

Detection dogs are sometimes taught to locate actual animals． Black-footed ferrets （雪貂） have been studied with their help． But more often the dogs learn to locate the waste of creatures such as bears, wolves and mountain lions．

What the dogs find provides scientists with data about a species． Scientists can use the DNA collected from animal waste to identify individuals, sex, and population sizes — all without ever seeing the animal itself． “It can take years to gather this kind of information if you have to trap animals,” Hurt explains．

Waste analysis might make a huge difference when wild species are accused of attacking domestic livestock （家畜）． Hurt says, “A good detection dog will find the waste so we can see what the animal is actually eating．” This may help reduce problems between people and wildlife．

The underlined word “She” in Paragraph 2 refers to  “_____”．

    A． the German shepherd                B． an African wild dog

    C． Aimee Hurt                        D． the handler

Oakley is interested in finding the waste because _____．

    A． he wants to study endangered animals

    B． he can get a tennis ball to play with

    C． he wants to eat it   

    D． he wants to play with it

Which of the following is TRUE according to the passage?

    A． Trapping animals is not difficult．

    B． People are making efforts to protect the environment．

    C． Detection dogs attack domestic livestock frequently．

    D． Collecting animal waste is a good way to gather information．

What is the main idea of the passage?

    A． Detection dogs can help scientists study wildlife．

    B． Detection dogs can defend wildlife．

    C． Detection dogs can help the police catch the criminals．

    D． Detection dogs can help local people defend domestic livestock．

Attempt a guess at the following question: In the English-speaking world, which country has the least affordable homes? You are wrong if you guessed the US, even with the housing bubble （气泡） and main sadness． Nor is it the UK, where prices have risen because demand is far from supply． According to a recent survey of 227 cities around the globe, you must go south of the equator （赤道） to Australia to find the priciest homes．

The report measured a city’s housing market along the following guidelines． An “affordable” home required three times or less of the average family’s income to purchase． At four times earnings, a home fell into the “unaffordable” category． And a “seriously unaffordable” home needed five times a family’s income． In Australia, homes in the least affordable city cost just about 9．5 times the average income． Sydney, Perth, and Melbourne were only a little under this figure．

Australian officials offered little comment, apart from a general statement on the dismal findings． These prices make the possibility that many Australians will one day own a home largely unbelievable． Land rationing （配给制） and excessive development charges have raised prices, and the problem will only be solved through urgent action by the Rudd government．

Some American cities were also included on the least affordable list, four of which were in California． America is still involved in a mortgage（抵押）crisis, though, affecting the affordability of homes． Yet a number of US cities garnered “affordable” status, namely Dallas and Kansas． Australia had no cities listed in the top fifty places with affordable homes．

The survey suggests that you can find affordable homes in most places, just not if you’re Australian and choose to live down under．

To buy an affordable house, you should pay _____．

   A． 3 times or less of the average family’s income

    B． 4 times or less of the average family’s income

    C． 5 times or less of the average family’s income

    D． 9．5 times or less of the average family’s income

What caused the prices of houses to increase in Australia?

   A． The rising family’s income．       B． The demand over supply．

   C． The excessive development charges． D． The decrease of land．

The underlined word “dismal” in Paragraph 3 may mean _____．

   A． cheerful       B． satisfactory

   C． difficult           D． gloomy 

What might be the most suitable title for the passage?

    A． Affordable Houses   B． A House is a Dream First

    C． Housing Bubble      D． Homes Too Expensive

Many years ago, when I was fresh out of school and working in Denver, I was driving to my parents’ home in Missouri for Christmas. I stopped at a gas station(加油站) about 50 miles from Oklahoma City, where I was planning to stop and visit a friend. While I was standing in line at the cash register(收款台), I said hello to an older couple who were also paying for gas.

I took off, but had gone only a few miles when black smoke poured from the back of my car. I stopped and wondered what I should do. A car pulled up behind me. It was the couple I had spoken to at the gas station. They said they would take me to my friend’s. We chatted on the way into the city, and when I got out of the car, the husband gave me his business card.

I wrote him and his wife a thank-you note for helping me. Soon afterward, I  received a Christmas present from them. Their note that came with it said that helping me had made their holidays meaningful.

Years later, I drove to a meeting in a nearby town in the morning. In late afternoon I returned to my car and found that I’d left the lights on all day, and the battery(电池) was dead. Then I noticed that the Friendly Ford dealership—a shop selling cars—was right next door. I walked over and found two salesmen in the showroom.

“Just how friendly is Friendly Ford?”I asked and explained my trouble. They quickly drove a pickup truck to my car and started it. They would accept no payment, so when I got home, I wrote them a note to say thanks. I received a letter back from one of the salesmen. No one had ever taken the time to write him and say thank you, and it meant a lot, he said.
