71 It might understand more than you think．
A dog named Rico recognizes the names of about 200 objects, say researchers in Germany． 72 Its word-learning skills are as good as those of a parrot or chimpanzee．
In one experiment，the researchers took all 200 items that Rico is supposed to know and divided them into 20 groups of 10 objects． 73 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． 74
The correct object was chosen in seven out of 10 tests．suggesting that the dog had worked out the answer by process of removing．A month later，Rico remembered half of the new names，which is even more impressive．
75 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!

It was the district sports meet. My foot still hadn’t healed(痊愈)from a(n) injury. I had whether or not I should attend the meet. But there I was, for the 3, 000-meter run.
“Ready. . . set. . . ”The gun popped and we were off. The other girls rushed me. I felt as I fell farther and farther behind.
“Hooray! ”shouted the crowd. It was the loudest I had ever heard at a meet. The first-place runner was two laps(圈)ahead of me when she crossed the finish line. “Maybe I should , ”I thought as I moved on. , I decided to keep going. During the last two laps, I ran and decided not to in track next year. It wouldn’t be it, even if my foot did heal.
When I finished, I heard a cheer— than the one I’d heard earlier. I turned around and enough, the boys were preparing for their race. “They must be cheering for the boys. ”I was leaving several girls came up to me. “Wow, you’ve got courage! ”one of them told me.

This was not because the woods and fields were always far away, but because they were too far from the city to permit people to make a day trip between morning and nightfall.
He decided to turn his little school house into a dormitory for the summer holidays. Anyone who brought his sleeping bag and cooking equipment along could stay there for a very small quantity of money. The idea was a success. A few years later, the school house was much too small to hold the many young people who wanted to stay there. This was the first hostel(青年招待所).
Today, young students and workers of every country can meet in the hostel and get to know each other. When young people arrive at the hostel, they have only to show their cards of membership in a hostel organization in their own country.
Often, at the evening meal, a group of boys and girls from various parts of the country or world will happen to meet at the same hostel. They may put their food together and prepare a dinner with many kinds of dishes. Sometimes a program will be organized after the meal with dances, songs, or short talks followed by a question period. For this reason, a few weeks spent ‘hostelling’ can be just as useful a part of one’s education as classes in school.
A．In 1970, a young German school master had an idea which changed this situation. B．People could stay in the hostel if they brought enough equipment with them. C．One can learn a lot about other places, just by meeting people from those places. D．As a result, a dormitory was set up in an old castle nearby.
The oldest stone buildings in the world are the pyramids(金字塔). They have stood for nearly 5, 000 years, and it seems likely that they will continue to stand for thousands of years yet. There are over eighty of them scattered(散布)along the banks of the Nile, some of which are different in shape from the true pyramids. The most famous of these are the “Step” pyramid and the “Bent” pyramid. 
Some of the pyramids still look as much alike as they must have been when they were built thousands of years ago. Most of the damage suffered by the others has been at the hands of men who were looking for treasure or, more often, for stones to use in modern buildings. The dry climate of Egypt has helped to keep the pyramids in good condition, and their very shape has made them less likely to fall into ruin. These are good reasons why they can still be seen today, but perhaps the most important is that they were planned to last forever.
The “Step” pyramid had to be on the west side of the Nile, the side on which the sun sets. This was for spiritual reasons. It also had to stand well above the level of the river to protect it against the regular floods. It could not be too far from the Nile, however, as the stones to build it needed to be carried in boats down the river to the nearest point. Water transport was, of course, much easier than land transport. The builders also had to find a rock base, which was not likely to crack(破裂)under the great weight of the pyramid. Finally, it had to be near the capital, or better still near the king’s palace so that he could visit it easily to personally check the progress being made on the final resting place for his body. According to the passage, the “Step” pyramid .

“Avoid the rush hour” must be the slogan of large cities all over the world. Wherever you look, there are people, people, people. The trains which leave or arrive every few minutes are packed. The streets are so crowded; there is hardly room to move on the pavements. It takes ages for a bus to get to you because the traffic on the roads has almost come to a standstill. Even when a bus does at last arrive, it’s so full, and it can’t take any more passengers. The smallest unexpected event can bring about conditions of complete chaos. The strange thing is not that people stand these conditions, but that they actually choose them in preference to anything else. 
Large modern cites are too big to control. People living there are forced by their environment to take a wholly unnatural way of life. They lost touch with the land and rhythm of nature. It is possible to live in such an air-conditioned existence in a large city that you can hardly tell the season. A few flowers in a public park may remind you that it is spring or summer. All the simple, good things of life like sunshine and fresh air are hard to find. Even the distinction between days and nights is lost.
The funny thing about it all is that you pay dearly to live in a city. The demand for accommodation is so great that it is often impossible for ordinary people to buy a house of their own. The cost of living is also very high. Just about everything you buy is likely to be more expensive than it would be in the country. Besides, the crime rate in most cities is very high.

| D．people still choose to live in a city |
City people can hardly tell the seasons because .
| A．there in no such thing as changes of seasons |
| B．seasons change only in public parks now |
| C．they live unnaturally without contact with nature |
