Not long age, experiments showed that birds rely on the sun to guide them during daylight hours. But what about birds that fly by night？ Tests with artificial stars have proved that certain night - flying birds are able to follow the stars in their long - distance flights.
A dove (鸽子) had spent its lifetime in a cage and had never flown under a natural sky. Yet it showed an inborn ability to use the stars for guidance. The bird's cage was placed under an artificial star - filled sky. (76) The bird tried to fly in the same direction as that taken by his outdoor cousins. Any change in the position of the artificial stars caused a change in the direction of his flight.
(77) But the stars are apparently their principal means of navigation (航行) only. When the stars are hidden by clouds, they seemingly find their way by such landmarks as mountain ranges, coast lines, and river courses. But when it's too dark to see these, the doves circle helplessly, unable to find their way.
The reason why birds don't get lost on long flights ______.
A．have been known to scientists for many years
B．have only recently been discovered
C．are known by us
D．will probably remain a mystery
Your Bean Steak (素肉排), Sir!
What sort of food are we likely to be eating in the year 2000？
Most people, when you ask them a question like that, either say: " There won't be any left, " or "Whatever it is, there won't be much taste in it." Of course, there are good reasons for being worried about the world's food supplies in the future.Nevertheless, not all the experts share these worries.
For one thing, although the world's population is rising fast, food production is keeping pace with it, even in developing countries.It is therefore argued that the main reason why people are hungry is not that there is a world food shortage but that methods of cultivation are not sufficiently advanced in some areas and the food is not fairly distributed (分配 ).
This does not mean, however, that our diet (饮食 ) will go on being the same.In many industrialized countries, people feed animals with grain to produce high-quality beef, even though the grain would feed the human population, and use fishmeal to fatten pigs to improve the quality of bacon.While not many of us would like fishmeal for lunch, its nutritional value is high and the unattractive fish it is made from can be presented to the public in colorful packets of fish fingers.
By the year 2000, many of these problems will have been solved.Scientists are already capable of making steaks from soy beans.It is quite obvious that there will still be enough to eat, if we are not too particular about where the food comes from and what it is made of.
1.Most people believe that food supplies in the future().
A、will become a very serious problem
B、will be the same as they are today
C、will be enough in quantity but not good in quality

A、poor farming methods and bad distribution
B、slow growth of food production
C、food shortages all across the world
D、fast rising population
3.The word "bacon" in Line 5, Para.3 most probably is().
A、a kind of "meat" made from grain
B、meat made from fish
C、food for fish
D、meat made from pigs
4.The word "particular" in Line 4, Para.4 means().
A、special
B、choosy
C、detailed
D、very exact
5.The title of this passage suggests that().
A、food in the future will be tasteless
B、there will be worldwide food shortages
C、diet in the future will be very different
D、science is making rapid progress

There is apparent generation gap between the young and the old nowadays. The younger generation is essentially different from the older generation. The young people live in a new age completely different from the old. They have grown up more happily and are not so dependent on adults as their parents were. They are better educated and enjoy more freedom. They easily accept new things and new ideas. They are more concerned with the present and the future, whereas the world of the older people has vanished, and they do not understand all of the problems of the modern world. They grew up in a world which was different from today's world. They often talk about "the good old days" and tend to assert old things and ideas. They don't like to feel that their beliefs and values are being questioned and threatened. They would like the young to learn from them, but the young refuse to accept their values. They cannot understand why the young complain about the conventional things and old systems and why they want to make changes in these things to fit the needs of modern society, As a result, the old people think the young are not what they were, and most young people are unable to learn from the parents and elders who they will never be.
In order to reconcile the differences, both generation should realize that the world has changed, and that new responses are necessary for many of the problems of society. Besides, some forms of organizations should be established to help the young and the old exchange their ideas and strengthen their mutual understanding so as to bridge the gap.
One important reason for the difference existing between the young and the old is that ______.
A．they live in different ages
B．they live in different countries
C．they live in separate planets
D．they hate each other
