For more than twenty years scientists have been seeking to understand the mystery of the‘‘sixth sense"of direction.By trying out ideas and solving problems one by one,they are now getting closer to one answer.
One funny idea is that animals might have a built-in compass(指南针).
Our earth itself is a big magnet(磁体).So a little magnetic needle that swings freely lines
itself with the big earth magnet to point north and south.When people discovered that idea about athousand years ago and invented the compass,it allowed sailors to navigate (航海)on oceanvoyages, even under
cloudy skies.
Actuallly the idea of the living compass came just from observing animals in nature.
Many birds migrate twice a year between their summer homes and winter homes.Some of them fly for thousands of kilometers and mostly at night.Experiments have shown that some birds can recognize star patterns.But they can keep on course even under cloudy skies.How can they do that?
A common bird that does not migrate but is great at finding its way home is the homing pigeon.Not all pigeons can find their way home.Those that can are very good at it,and they have been widely studied.
One interesting experiment was to attach little magnets to the birds’ heads to block their
magnetic sense—just as a loud radio can keep you from hearing a call to dinner.On sunny days, that did not fool the pigeons.Evidently they can use the sun to tell which way they are going.But on cloudy days,the pigeons with magnets could not find their way.It was as if the magnets had blocked their magnetic sense.
Similar experiments with the same kind of results were done with honeybees.These insects also seem to have a special sense ot direction.
In spite of the experiments,the idea of an animal compass seemed pretty extraordinary.How
would an animal get the magnetic stuff for a compass.
An answer came from an unexpected source.A scientist was studying bacteria that live in the
mud of ponds and marshes.He found accidentally little rod-like bacteria that all swam together in
one direction—north.
Further study showed that each little bacterium had a chain of dense particles inside,which
proved magnetic.The bacteria had made themselves into little magnets that could line up with the
earth’s magnet.
The big news was that a living thing,even a simple bacterium,can make magnetite.That led
to a search to see whether animals might have it.. By using a special instrument called magnetometer,scientists were able to find magnetite in bees and birds,and even in fish.In each
animal,except for the bee.the magnetic stuff was always in or closer to the brain.
Thus.the idea of a built—in animal compass began to seem reasonable.

Find Which Direction Is South
Do you have a good sense of direction? If not, please take with you a compass. But if you forget to take a compass, you can still find your way.
It’s never a good idea to imagine that the family member who was entrusted(委托)with the job of map-reading actually knows where the family is. You can tell by the slightly confused load on their faces that nothing on the ground seems to match the map. Never mind. The shu is shining and it’s still morning. If you don’t know the exact time, you can still find out where south is, but you’ll need to be patient.
①Find a straight sick and put it in the ground in a place where you can mark its shadow.
②Try to position the stick as vertically(垂直)as you can. You can check this by making a simple plumb line (铅锤线)with a piece of string and weight. You haven’t got any string? OK, use a thread from your clothes with a button tied at the end to act as a weight.
③Mark the end of the shadow cast by the stick.
④Wait approximately half an hour and mark the end of the shadow again.
⑤Keep doing this until you have made several marks.
⑥The mark nearest the stick will represent the shortest shadow, which is cast at midday, when the sun is highest in the sky and pointing to the exact south.
⑦Pick a point in the distance along the line between the shortest shadow and the stick.
⑧That point is south of where you are.
⑨Now you can turn the map, like you did before, and find which way you should be travelling.
6To find the direction, we ought to be patient probably because
A. it is not easy to find a proper stick
B. it is not easy to position the stick
C. it takes hours to make the marks
D. it takes about half an hour to make the marks
The passage would probably be most helpful to .
A. those who draw maps B. those who get lost
C. those who make compasses D. those who do experiments
Which of the following pictures best shows the way of finding the direction of south?
The author presents this passage by .
A. telling an interesting story B. describing an activity in a lively way
C. testing an idea by reasoning D. introducing a practical method

For many men an women today,the image that a watch communicates is more important than the time it tells. “Complications”---features that go beyond simple timekeeping—are an important part of a watch’s image. Today’s watches offer a host of complications that suit almost any personality . These features include altitude trackers ,compasses, lunar calendars ,USB drivers , and even devices that measure the effectiveness of golf swings !
Creativity is also a key element in today’s watches , for men as well as women. The Japanese watchmaker Tokyoflash makes watches that don’t even look like watches . The company’s popular Shinshoku model uses different color lights to tell the time . It looks more like a futuristic bracelet then a watch. Another Japanese watchmaker , EleeNo , makes a “handless” watch . Using a ring of circles to keep time , this watch makes an excellent conversation piece.
In the past, the image of a man’s watch was quite different from that of a woman’s. Men’s watches tend to be bolder, larger, and more complicated than women’s watches, which were more likely to look like jewelry. Today, the differences between men’s and women’s watches are disappearing. Watchmakers are adding diamonds to their fine watches for man. And for women, they’re designing larger watches that contain complications. For example, some women’s watches now have calendars that show the phrases of the moon. Others show the time in two different cities, a handy funtion for business travelers. However, women still pay more attention than most men to the external beauty of a watch. And unlike men, women are still more likely to purchase watches that suit particular items in their wardrobes.
72.According to the passage, one type of watch complications can show you____________.
A. appointments for the day B. which direction is north
C. how much weight you’ve put on D. a list of telephone numbers
73.What is the true information about the watch made by EleeNo?
A. It uses different hands to keep time. B. It’s rather popular.
C. It doesn’t look like a watch. D. It’s much fun to talk about.
74.What does the writer imply about watches for women?
A. They are not as simple as they used to be.
B. They need to improve their quality.
C. They have fewer functions and jewels.
D. They don’t last as long as they used to.
75. What is the main topic of this article?
A. Why women are likely to buy more watches than men?
B. The differences between men’s and women’s watches
C.Current trends in the watch industry.
D.Useful tips for purchasing watches.
