Next fall when you see geese heading south for the winter or flying in “ V” formation (队形), you might consider what science has discovered as to why they fly that way.

As each bird spreads its wings，it creates an uplift (上升力) for bird immediately following. By flying in “ V” formation the whole flock (鸟群) adds at least 71% greater flying range, than if each bird flies on its own. People who share a common direction arid sense of community can get where they are going more quickly and easily because they are traveling on the thrust (推动力) of one another.

When a goose falls out of the formation, it suddenly feels the drag and resistance of trying to go it alone and quickly gets back into formation to take advantage of the lifting power of the bird in front. If we have as much sense as a goose, we will stay in formation with those who are headed the same way we are. When the head goose gets tired, it flies backwards and another goose flies point. It is sensible to take turns doing demanding jobs, whether it is with people or with geese flying south.

Geese honk (雁叫) from behind to encourage those up front to keep up their speed. What do we say when we honk from behind?

Finally and this is important, when a goose gets sick or is wounded by gunshots, and falls out of formation, two other geese fall out with that goose and follow it down to lend help and protection. They stay with the fallen goose until it is able to fly or until it dies, and only then do they launch out on their own, or with another formation to catch up with their group. If we have the sense of a goose, we will stand by each other like that.

1.The first three paragraphs chiefly deal with 　　　　　 .

A. scientific discovery about geese.

B. the importance of flight formation.

C. the advantages of “V” formation.

D. the reasons for geese’s flight.

2.The phrase which can best replace “stand by” in the last sentence is “　　　　　 ”.

A. be against.　　 B. support.

C. sit by.　　 D. obey.

3.What does the author want us to learn from the geese?

A. Teamwork.　　 B. Sympathy.

C. Kindness.　　 D. Intelligence.

Next autumn when you see wild geese heading south for the winter flying in a V formation, you might think about what scientists have discovered as to why they fly that way.

As each bird flaps its wings, it creates uplift(提升) for the bird immediately following. By flying in a V formation the whole group adds at least 71% greater flying range than if each bird flies on its own.

People who share a common direction and sense of community can get where they are going more quickly and easily because they are traveling on the push of one another.

When a wild goose falls out of the formation，it suddenly feels the drag and resistance of trying to go alone and quickly tries to get back into the formation to take advantage of the lifting power of the bird in front. When the head goose gets tired，it flies back into the formation and another goose flies to the front. It is wise to take turns doing difficult jobs whether it is people or wild geese flying south.

Wild geese honk (发出雁叫声) from behind to inspire those up front to keep up their speed. What can we learn from this?

When a wild goose gets sick or wounded by gunshots，and falls out of the formation，two other geese will fall out with that goose and follow it down to lend help and protection. They will stay with the fallen goose until it is able to fly or until it dies，and only then will they go on with their own or with another formation to catch up with their group.

1.Wild geese fly in a V formation in order to________.

A. protect themselves from danger

B. fly more quickly and easily

C. help the sick and wounded

D. fly much higher in the sky

2.What can we learn from the fifth paragraph?

A. We should try to lead others to move forward.

B. We should give people facing difficulties encouragement.

3.When a wild goose becomes sick or is wounded，________.

A. it will be left alone and will fall on the ground

B. the whole group will stop flying

C. two other geese will stay with it to offer help

D. other geese will honk to give it encouragement

4.What do we know from the passage?

A. A wild goose can help the one following it by flapping its wings.

When you cough or sneeze, you’d better turn your head away from others and cover your mouth with the full part of your hand. And then, you should say, “Excuse me.”

This seems so simple, but it is surprising how many kids have never been told to do this. Actually, I notice adults all the time who cough and sneeze in public without placing a hand over the mouth. One important thing I point out to the kids is that after they sneeze or cough on their hands, they should wash their hands as soon as possible. If not, they will be passing those germs (细菌) along to everything and everyone they touch.

If you come to a door and someone is following you, hold the door. If the door opens by pulling, pull it open, stand to the side, and allow the other person to pass through first, then you can walk through. If the door opens by pushing, hold the door after you pass through.

After a few weeks of seeing kids try to get through doors in the school and watching them enter restaurants as the door hit other people, I knew I had to discuss the problem with my students. Teaching them small acts of kindness, such as letting someone else go through a door first as they hold it open, may seem unimportant, but it can go along way toward helping students realize hot to be polite and thank others. Once they’ve been told, they’re halfway there.

When we have to go up moving stairs, we will stand to the right. That will give others who are in a hurry a choice of walking up the left-hand side of the moving stairs. When we are going to enter a lift, the underground, or a doorway, we will wait for others to exit before we enter.

After college when I moved to London, I was surprised at how polite everyone was in the subways. I was even more touched when I traveled to Japan. In both places, people made efforts to make way for others. On moving stairs, everyone stood to the right and walked to the left. On lifts, everyone would stand over to the side and allow others to exit before they would begin to enter.

1.When you cough or sneeze, you should ________.

A. touch everything             B. cover your mouth

C. point out to the kids        D. pass the germs to others

2.If you come to a door and someone is following you, you’d better _______.

A. hold the door  B. pass through  C. close the door  D. stand to the side

3.From the passage we ca know the writer is a ________.

A. doctor       B. traveler             C. parent               D. teacher

4.A. The passage is mainly about ______.

A. the rules of behavior in public          B. the easy of communication

C. the acts of kindness among people        D. the knowledge of social life

In late summer or early fall the large, yellow seed heads of sunflowers will be ripening. If gardeners can keep off the birds and other wildlife trying to eat the seeds, they can have a large harvest. The bright yellow blooms will make a rainbow garden, brightening up any space.

However, planting the sunflower seeds is a skilled job. Plant seeds no deeper than the full length of itself. Smaller sized sunflowers can be spaced a foot apart. Larger varieties will need to be spaced as far apart as three feet. This allows ripe plants enough space for the seed heads to ripen without knocking the ripe seeds off before gardeners have a chance to harvest them.

Most sunflower seeds, especially those with eatable seeds, are large enough to handle without the need for seed sorters. This is why sunflowers make an excellent choice for a children's garden as well. Gardeners will want to mix plenty of soil fertilizers into the ground as sunflowers tend to be heavy feeders.

Sunflowers can be slow starters and the tiny new plants don't seem to grow very rapidly. Gardeners should protect the new plants as they begin to grow. Once they get going, sunflowers are able to out-grow many weeds, making them easier to grow in the home vegetable garden than many other plants.

Most pests and diseases are not a bother to the sunflower, however, more than one gardener has said that their lovely looking plants were destroyed overnight by hungry squirrels, mice or birds. To preserve their harvest, gardeners can cover the ripening seed head with stockings or net cloth to help keep the destroyers off the seeds.

Planting sunflower seeds is easy and can help even the smallest gardener feel successful in their gardening attempts.

1.What is the passage mainly about?

A. How to plant sunflowers.

B. Different kinds of sunflowers.

C. Ways to preserve sunflowers.

D. Tips on making your garden bright.

2.Why should enough space be left between sunflowers?

A. To prevent birds from eating sunflower seeds.

B. To offer the sunflowers enough sunlight.

C. To protect the ripe seed heads before harvest.

D. To help the sunflowers grow stronger.

3.Why do children love to grow sunflowers in their garden?

A. They want to decorate their garden with sunflowers.

B. The seeds are easy to plant and unnecessary to sort.

C. They want to share their own harvest with their parents.

D. Sunflowers don’t need too much soil fertilizer.
