"I was in the wrong for leaning over the barrier, but I do think the zoo should look into moving their fence back," she told CBS News. "I'm not the first, and if they don't move the fence, I'm probably not going to be the last."

　　Kitty Block, president and CEO of the Humane Society of the United States, also urged the zoo and other parks to be cautious enough when it comes to separating the animals from people.

　　"When various types of exhibitors promote all sorts of close meeting with wildlife, people get the mistaken idea that wild animals are approachable," she said in a statement. "We urge the zoological community exhibitors to set a higher standard to protect people and to respect wildlife from a safe distance by doing away with public contact opportunities with wildlife of all species."

4. How did Leanne free from the danger of the jaguar?

　A. The zoo director helped her to get away from it.

　B. The jaguar was attracted by a bottle and let her go.

　C. Another park goer hurt the jaguar and it ran away.

　D. Leanne herself struggled with it and scared it away.

5. What can we infer from Paragraph 5?

　A. Human behavior cannot have any influences on the jaguar in the zoo.

　B. The jaguar tends to attack the guests unexpectedly however far they stay.

　C. Leanne is doubtful whether the barrier around the exhibit is safe enough.

　D. The zoo has ensured the barrier will be evaluated again after the accident.

6.What did Kitty Block advise the zoo and parks to do?

　A. Be very cautious to separate the animals from people.

　B. Look into moving their fence back and clear the barrier.

　C. Set a higher standard to build up a zoological community.

　D. Encourage people to have frequent meetings with wildlife.

　　Robot vacuum cleaners aren't a new concept, having been around for more than 15 years, but they have become greatly more helpful since the days of catching on rug hairs, running out of battery mid-clean and forgetting where they were.

　　But the next generation of disc-shaped floor-cleaners could bring some of the most important upgrades yet, including being more autonomous than ever and knowing exactly where they are in your home and where you need them to be.

　　iRobot's latest Roombas, the i7 and i7+, shown off at a recent event in Tokyo, will be arriving in Australia in the coming months. Their key new feature: persistent mapping of your home. The ability to map not only makes the robot quicker and more efficient, but lets it integrate(融入) more closely with smart homes. Once it's explored your house a few times, the i7 will present you with a map via its smart phone app, which Angle says tends to be "maybe 80 per cent right".

　　As the robot travels around cleaning up dust, it draws a floor plan and uses a sensor(传感器) to identify landmarks and objects. Unlike previous models, the i7 remembers this information, meaning it will learn the most efficient paths around your home over time.

　　If you change the layout of your furniture, it will adapt the existing map rather than having to create a whole new one and if you have a multi-storey house, it simply makes multiple maps, and uses its learned landmarks to determine which floor it's on (you'll still need to carry it up the stairs).

　　iRobot's CEO and founder Colin Angle says the i7 class, the company's 10th generation Roomba, is the robot he's always wanted to build; capable of keeping a home's floors clean with virtually no user input needed.

　　"This robot has 30 times the processing power of its former generation," he says. "So we're fully into a situation today where we can be running machine learning and visual object recognition technology and very advanced algorithms(演算法; 运算法则) on the robot, to allow it to continue to work on increasingly complicated code."

7. According to the passage the robot cleaners invented 15 years ago could ______.

A. catch on the hairs on the rug

　A. arrangement B. design C. style D. size

9. Which of the following statements about the i7 and i7+ is true?

A. i7 remembers the identified landmarks like former models.

B. They can enter the room upstairs themselves and clean it.

C. They can do better in math than the previous cleaners.

D. i7 can present a map exactly via its smart phone app.

10. What can be the best title of the passage?

A. Technologies in the Cleaner. B. The Future of iRobots.

C. The Development of iRobots. D. The Latest Robot Cleaner.
