　　Soil conservation(保护) efforts protect soil from wind and water that can blow or wash it away. Good soil produces food crops for both humans and animals. One important form of soil conservation is the use of windbreaks. Windbreaks stop the wind from blowing soil away. They also keep the wind from destroying or damaging crops. Windbreaks are barriers formed by trees and other plants with many leaves. Farmers plant windbreaks in lines around their fields. They are very important when grains such as wheat are grown. Windbreaks are effective when a wall of trees and other plants blocks the wind. The windbreaks should also limit violent motions of the wind to those areas closest to the windbreak.

　　Windbreaks seem to work best when they fallow a little wind to pass through. If the wall of trees and plants stops wind completely, then violent air motions will take place close to the ground. These motions cause the soil to lift up into the air where it will be blown away. For this reason, a windbreak is best if it has only 60 to 80 per cent of the trees and plants needed to make a solid line. An easy rule to remember is that windbreaks can protect areas up to ten times the height of the tallest trees in the windbreak. There should be at least two lines in each windbreak. One line should be large trees. The second line, right next to it, can be formed from shorter trees and other plants with leaves. Windbreaks not only protect land and crops from the wind. They can also provide wood products. These include wood for fuel and longer pieces for making fences. Locally-grown trees and plants are best for windbreaks.

1．Which of the following statements is NOT true?

[　　]

A．A windbreak increases violent motions of the wind.

B．A windbreak stops the wind from destroying the crops.

C．A windbreak provides wood products for fuel and other purposes.

D．A windbreak is a form of soil conservation.

2．Why should windbreaks allow a little wind to pass through?

[　　]

A．So as to prevent violent air motions taking place.

B．So that the crops can breathe enough fresh air.

C．So as to save a lot of money by planting fewer trees.

D．Because a little wind helps the crops grow better.

3．10-metre-high windbreak can protect crops as far as _____ metres away.

[　　]

A．60-80　　　B．100

C．10　　　　 D．50

4．The passage is mainly about _____.

[　　]

A．soil conservation　　B．crops and winds

C．windbreaks　　　　D．how to plant trees

As they migrate（迁移) , butterflies and moths choose the winds they want to fly with, and they change their body positions if they start floating in the wrong direction. This new finding suggests that insects may employ some of the same methods that birds use for traveling long distances. Scientists have long thought that insects were simply at the mercy of the wind.

Fascinating as their skills of flight are, migrating behavior has been difficult to study in insects because many long distant trips happen thousands of feet above ground. Only recently have scientists developed technologies that can detect such little creatures at such great heights.

To their surprise, though, the insects weren't passive travelers on the winds. In autumn, for example, most light winds blew from the east, but the insects somehow sought out ones that carried them south and they positioned themselves to navigate directly to their wintering homes.

Even in the spring, when most winds flowed northward, the insects didn't always go with the flow. If breezes weren't blowing in the exact direction they wanted to go, the insects changed their body positions to compensate. Many migrating birds do the same thing.

The study also found, butterflies and moths actively flew within the air streams that pushed them along. By adding flight speeds to wind speeds, the scientists calculated that butterflies and moths can travel as fast as 100 kilometers an hour. The findings may have real-world applications. With climate warming, migrating insects are growing in number. Knowing how and when these pests move could help when farmers decide when to spray their crops.

What's the main idea of the text?

A. Windsurfing insects have real direction.

B. Wind helps insects greatly in migrating.

C. Insects migrate with the seasons.

D. Scientists have trouble in observing insects.

Scientists originally thought that _____.

A. insects were just blown about by the wind

B. insects chose the winds they wanted to ride

C. insects always waited for their favourable winds

D. insects positioned themselves in the winds

It is not easy to study the migrating behavior of the insects because ______.

A. the little creatures can fly very fast

B. their flight is long and high above ground

C. the wind's direction is hard to foresee

D. they have no regular migrating courses

We can learn from the text that _____.

A. insects never position themselves when flying low

B. insects travel more easily in autumn

C. insects fly in the way birds do

D. insects rest a lot when the wind pushes them along

“Tomorrow is another day”---- this line has impressed various people at various times. It's now 70 years after it appeared in the film, but it still seems to hold its power especially during an economic downturn.

The phrase comes from a film adaptation of Margaret Mitchell's successful 1936 novel Gone With the Wind. It's set in the American South and tells the story of a strong heroine, Scarlett O' Hara, who struggles to find love during the Civil War and, afterwards, of her strength in surviving the war and its hardships.

Love story

In a moment of despair, Scarlett finally realizes that her love belongs to Rhett Butler. For many audiences, it is the theme of love and struggle that has kept the movie alive. While the burning of Atlanta might seem irrelevant to today's viewers, the timeless theme of love keeps its ability to touch people.

With a promise to her lover still in her mind, Scarlett chooses to stay in the midst of war and take care of Melanie. But her heart is broken when Rhett just walks away, leaving the woman that he once loved with cruel words, "Frankly, dear, I don' t give a damn."

Great epic

The film shows the love-hate relationship of these characters, but also American history, the fall of the Confederacy and the following period of Reconstruction in the South. The background made this film a true classic in the epic genre.

When the film opened after World War II, French viewers loved it, and it reminded them of their fight against the Nazis. In 1940 Shanghai, during the War of Resistance Against Japanese Aggression, people stood in line for hours to watch this film, and saw the same suffering they were having as well as the hope and possibility of building a new homeland from the ruins.

Each nationality could identify with the story and see it as a victory. In fact, Gone With the Wind never lost its charm and ability to inspire and amaze.

Biggest of all time

The film had five directors, 15-plus screenwriters, and an unexpected $3.9 million budget. The film brought in $ 200 million, which makes it the biggest selling film of all times in North America. It also won 10 Academy awards in 1940.

A．the novel Gone with the Wind	B．"tomorrow is another day"
C．the movie Gone with the Wind	D．the Academy Award

A．celebrate the anniversary of Margaret Mitchell

B．introduce how the film was directed and filmed

C．throw light on the charm of the movie "Gone with the Wind"

D．inspire people to struggle the economic downturn

3.It can be concluded that Scarlett O' Hara is _______.
