     The secret of carrier pigeons' unbelievable ability to find their way home has been discovered by
scientists: the feathered navigators follow the roads just like we do.
     Scientists now believe the phrase "as the crow (乌鸦) flies" no longer means the shortest most
direct route between two points. They say it is likely that crows and other day birds also choose
AA-suggested routes, even though it makes their journeys longer.
     Scientists at Oxford University  spent 10 years studying homing pigeons using global positioning
satellite (GPS) and got a surprising result. The birds often don't use the sun to decide their directions.
     Instead they fly along motorways, turn at crossing and even go around roundabouts (绕道) , adding
miles to their journeys.
     "It really has knocked our research team sideways to find that after a decade-long international
study, pigeons appear to ignore their inbuilt directional instincts (本能) and follow the road system,"
said Prof Tim Guilford, reader in animal behavior at Oxford University's Department of Zoology.
    Guilford said pigeons use their own navigational system (导航系统) when doing long distance trips
or when a bird does a journey for the first time.
     "But once homing pigeons have flown a journey more than once, they can fly home on a habitual
route, much as we do when we are driving or walking home from work," said Guilford.
      "In short, it looks like it is mentally easier for a bird to fly down a road. They are just making their
journey as simpl e as possible."

1.What would be the best title of the passage?

A. Birds Follow Roads as We do.
B. Why Pigeons Can Fly long Distance?
C. How Pigeons Find Their Ways Home?
D. Why Crows Fly the Shortest Distance?

2.What does the words "the feathered navigators" refer to?

A. The pigeons.
B. The crows.
C. Day birds.
D. Animals that can fly.

3.Scientists used to think that homing pigeons often find their directions _______.

A. by global positioning satellite
B. by the sun
C. by the road system
D. by following other birds

4.Why do homing pigeons tend to follow the road system during the journey?

A. Because they don't have their inbuilt directional instincts now.
B. Because their own navigational system doesn't work.
C. Because it is too hard to use their own navigational system.
D. Because it is easier to make journey simple by following road system.

The editor must never forget that the success of any newspaper depends on advertising. He is usually anxious to keep the good will of local businessmen for this reason. But if the newspaper is well written and the news items have been carefully chosen to attract local readers, the businessmen are thankful for the opportunity to keep their products in the public eye.

Local newspapers do not often comment on problems of national importance and editors rarely take sides on political questions. But they can often be of service to the community in expressing public feeling on local issues. A newspaper can sometimes persuade the council to take action to provide better shopping facilities, improve transport in the area and preserve local monuments and places of interest.

These papers often sound rather dull and it seems surprising that they all make a profit, but for many people in small towns and villages the death of someone known to them or the fix of traffic lights at a busy corner nearby can sometimes be more important than a disaster in a foreign country.

1. What should the editor remember according to the first paragraph?

A. Money.　　　　　　　　　　　　 B. Newspaper.

C. People.　　　　　　　　　　　　 D. Advertising.

2. What is the local newspapers' attitude on national political questions?

A. They seldom have their own ideas.

B. They often express their ideas.

C. They are against one side.

D. They are for another side.

3. Do businessmen like the local newspapers?

A. No, they are for business.

B. Yes, from the advertising on the newspapers they can sell well.

C. Yes, they can write for the newspaper.

D. No, they can't get much money from the newspaper.

4. A local newspaper can persuade the council ________.

A. to provide better shopping facilities

B. to preserve local monuments

The easy way out isn't always easiest . I learned that lesson when I decided to treat Doug , my husband of one month , to a special meal . I glanced through my cookbook and chose a menu(菜谱) which included homemade bread . Knowing the bread would take time , I started on it as soon as Doug left for work . As I was not experienced in cooking , I thought if a dozen was good , two dozens would be better , so I doubled（加倍）everything . As Doug loved oranges , I also opened a can of orange and poured it all into the bowl . Soon there was a sticky dough (面团) covered with ugly yellowish marks . Realizing I had been defeated , I put the dough in the rubbish bin outside so I wouldn't have to face Doug laughing at my work , I went on preparing the rest of the meal , and , when Doug got home , we sat down to eat Cornish chicken with rice . He tried to enjoy the meal but seemed disturbed . Twice he got up and went outside , saying he thought he heard a noise . The third time he left , I went to the windows to see what he was doing . Looking out , I saw Doug standing about three feet from the rubbish bin , holding the lid up with a stick and looking into the container . When I came out of the house , he dropped the stick and explained that there was something alive in our rubbish bin . Picking up the stick again , he held the lid up enough for me to see . I felt cold . But I stepped closer and looked harder . Without doubt it was my work . The hot sun had caused the dough to double in size and the fermenting yeast (酵母)made the surface shake and sigh as though it were breathing .It looked like some unknown being from outer space. I could see why Doug was so shaken. I had to admit what the 'living thing” was and why it was there . I don't know who was more embarrassed(尴尬)by the whole thing － Doug or me.

The blue tits(山雀) have been inspecting the nest-box again this year. The male is the house-hunter but the female will make the final choice. He lands at the hole and turns his head to expose his white cheeks as a signal to attract the female from where she has been feeding.
Among many birds that nest in holes, the male has a light-coloured patch on its plumage(鸟羽) which acts as signal for drawing the female’s attention to a suitable nesting-place. Unlike the blue tit, the redstart(红尾鸲) may be only the male that strikingly coloured and the female is not beautiful.
A few years ago I was lucky enough to spot a pair of redstarts in action in a Walsh wood. The male was leading an interested female to holes that he had previously(先前) checked out. He sat at the entrance of each hole and put his head on to show off his white forehead, or his head in to reveal(显露) his tail.
If the female failed to react to his visual signals, the male sometimes sang for extra effect, while gliding towards her on spread wings and tail. Once the female accepts by following the male through the hole the displays stop, you must be at the right place at the right time to watch them.
36. How do the blue tits choose their nest?
A. They choose their nest together.
B. The male chooses their nest.
C. The house-hunter chooses their nest.
D. The female chooses their nest.
37. The writer was lucky to see ________.
A. how the male made his tricks
B. how an interested female played with the male happily
C. what the male displayed and won the female
D. that the male tried his best but failed to attract the female
38. You can spot a pair of redstarts in a Walsh wood ________.
A. at any time        B. regularly    C. in April    D. occasionally
39. The writer is probably ________.
A. a bird expert     B. a bird-hunter   C. a bird raiser   D. a scientist
