Modern inventions have speeded up people’s loves amazingly. Motor-cars cover a hundred miles in little more than an hour, aircraft cross the world inside a day, while computers operate at lightning speed. Indeed, this love of speed seems never-ending. Every year motor-cars are produced which go even faster and each new computer boasts (吹嘘) of saving precious seconds in handling tasks.

All this saves time, but at a price. When we lose or gain half a day in speeding across the world in an airplane, our bodies tell us so.  We get the uncomfortable feeling known as jet-lag; our bodies feel that they have been left behind on another time zone. Again, spending too long at computers results in painful wrists and fingers. Mobile phones also have their dangers, according to some scientists; too much use may transmit harmful radiation into our brains, a consequence we do not like to think about.

However, what do we do with the time we have saved? Certainly not relax, or so it seems. We are so accustomed to constant activity that we find it difficult to sit and do nothing or even just one thing at a time. Perhaps the days are long gone when we might listen quietly to a story on the radio, letting imagination take us into another world.

There was a time when some people’s lives were devoted simply to the cultivation of the land or the care of cattle. No multi-tasking there; their lives went on at a much gentler pace, and in a familiar pattern. There is much that we might envy about a way of life like this. Yet before we do so, we must think of the hard tasks our ancestor faced: they farmed with bare hands, often lived close to hunger, and had to fashion tools from wood and stone. Modern machinery has freed people from that primitive existence.

The new products become more and more time-saving because         .

A. our love of speed seems never-ending            B. time is limited.

C. the prices are increasingly high.                 D. the manufactures boast a lot.

What does “the days” in Paragraph 3 refer to?

A. Imaginary life                              B. Simple life in the past.

C. Times of inventions                          D. Time for constant activity.

What does the passage mainly discuss?

A. The present and past times.                   B. Machinery and human beings.

C. Modern technology and its influence.           D. Imaginations and inventions.

Be careful what you say around your dog. It might understand more than you think.

A border collie named Rico recognizes the names of about 200 objects, say researchers in Germany. The dog also appears to be able to learn new words as easily as a 3-year-old child. Its word-learning skills are as good as those of a parrot or chimpanzee(黑猩猩).

In one experiment, the researchers took all 200 items that Rico is supposed to know and divided them into 20 groups of 10 objects. Then the owner told the dog to go and fetch one of the items and bring it back. In four tests, Rico got 37 out of 40 commands right. As the dog couldn't see anyone to get clues, the scientists believe Rico must understand the meanings of certain words.

In another experiment, the scientists took one toy that Rico had never seen before and put it in a room with seven toys whose names the dog already knew. The owner then told Rico to fetch the object, using a word the dog had never heard before.

The correct object was chosen in seven out of l0 tests, suggesting that the dog had worked

out the answer by process of elimination(排除法). A month later, Rico remembered half of the new names, which is even more impressive.          

Rico is thought to be smarter than the average dog. For one thing, Rico is a border collie, a breed (品种)known for its mental abilities. In addition, the 9-year-old dog has been trained to fetch toys by their names since the age of nine months.

It's hard to know if all dogs understand at least some of the words we say. Even if they do, they can't talk back. Still, it wouldn't hurt to sweet-talk your dog every now and then. You might just get a big, wet kiss in return!

From paragraph 2 we know that __        .

A. animals are as clever as human beings

B. dogs are smarter than parrots and chimpanzees

C. chimpanzees have very good word-learning skills

D. dogs have similar 'learning abilities as 3-year-old children

Both experiments show that             .

A. Rico is smart enough to get all commands right

B. Rico can recognize different things including toys

C. Rico has developed the ability of learning mathematics

D. Rico won't forget the names of objects once recognizing them

Which of the following statements is true?

A. The purpose of the experiments is to show the border collie's mental abilities.

B. Rico has a better memory partly because of its proper early training.

C. The border collie is world-famous for recognizing objects.

D. Rico is born to understand its owner's commands.

Which may be the best title of the passage?

A. Do dogs understand us?                       

B. Does your dog understand you?

C. Be careful with dogs.                             

D. Be friendly to your dog.
