Some birds like eating locusts (蝗虫), but birds cannot easily catch them. Why? It is because locusts change their colors together with the change of the colors of crops(庄稼). When crops are green, locusts look green. But as the harvest time comes, locusts change to the same brown color as crops have. Some other pests with different colors from plants are easily found and eaten by others. So they have to hide themselves for lives and appear only at night.
If you study the animal life, you’ll find the main use of coloring is to protect themselves. Bears, lions and other animals move quietly through forests. They cannot be easily seen by hunters (猎人). This
is because they have the colors much like the trees.Have you ever noticed an even stranger act? A kind of fish in the sea can send out a kind of very black liquid (液体)when it faces danger. While the liquid spreads over (散开), its enemies (敌人)cannot find it. And it immediately swims away. So it has lived up to now though it is not strong at all.
36. From the passage we learn that locusts________.
A. are small animals B. are easily found by birds
C. are dangerous to their enemies D. change their colors to protect themselves
37. How can pests with different colors from plants keep out of danger?
A. They run away quickly.
B. They have the colors much like their enemies.
C. They hide themselves by day and appear at night.
D. They have to move quietly.
38. Bears and lions can keep safe because _________.
A. they have the colors much like the trees B. they move quietly
C. they like brown and gray colors D. they live in forests
39. Why can the kind of fish live up to now?
A. Because it is very and strong.
B. Because the liquid it sends out can help it escape from its enemies.
C. Because the liquid it sends out can kill its enemies.
D. Because it swims faster than any other fish.
40. Which is the best title for this passage?
A. The Change of Colors for Animals and Pests
B. Colors of Different Animals and Pests
C. The Main Use of Colors for Animals and Pests

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.

The two have worked together for almost 20 years. This year alone, they’ve fixed about 450 instruments. Both men are musicians and music lovers, so learning to do repairs came naturally.
“I have been a musician all my life.” says West. “I played in an orchestra here in the city. I majored in music in college. I played in an army band.”
Jernigan’s musical interests are varied. “I was formerly trained in the piano and guitar. The alto sax, and the flute, I picked up while working here.”
In addition to fixing instruments, the two also go to schools to instruct teachers and students on how to make minor repairs on their own.
West believes if children start early and stay involved with music, it enriches other areas of their lives. “I see that in other kids. I see it in myself. I have seen it hundreds of times and it works,” he says. “They learn teamwork. They learn patience and respect.
But West has concerns about the future of music in the electronic age.
“This instant age has taken away from the sit-down, the patience. And to learn to play an instrument, it takes patience, it takes diligence, it takes time.”
Being able to enjoy music on the job is one of the benefits of the job. Both men agree their best rewards are the students’ performances.
小题1: What’s the job of West and Jernigan at school?
| A．Teaching music. |
| B．Writing music. |
| C．Making musical instruments. |
| D．Repairing musical instruments. |
| A．earn more money | B．learn repair skills |
| C．enjoy music | D．watch performances |
| A．They have fixed 450 instruments in the past 20 years. |
| B．They can play and repair musical instruments. |
| C．Jernigan used to play in an army band. |
| D．West was trained to play the piano. |
| A．Teamwork and patience. | B．The value of time. |
| C．The truth of society. | D．Diligence and confidence. |
| A．How to repair musical instruments. |
| B．Learning experiences of two repairmen. |
| C．How to prepare a musical performance. |
| D．The enjoyable job of two music lovers. |
Even when the child is caught in a complete lie, this should not be the end of trust. A parent can tell a child that a single lie is forgivable. Yet it should be clear that if lies continue, the child, like the boy who cried wolf, will suffer loss of trust.
When my wife and I discovered that our son Tom, then 13, had lied about throwing a party while we were away, we grounded him for a month. We also told Tom that we could no longer trust him, and we could not allow him to stay alone overnight again. This loss of freedom was an important lesson; he learned how hard it is to live with people when they don’t trust him. As a result, now more than three years later we can again trust Tom to stay alone overnight.
Parents must always remember there is no easy answer to this universal problem of lying. We can set a good example, allow for privacy, monitor friendship, develop trust and punish wrong doing, but still we discover our child has lied to us. Finally that’s why there is a need for trust on both sides of a parent-child relationship. Lying destroys closeness and friendship. For that reason, parents should always try to give a child the feeling that they can be trusted with the truth. Parents may start with a child’s trust, but as the child grows older, parents must earn it.
小题1:When the writer and his wife discovered that their son had lied, they _________.
| A．took all his freedom from him |
| B．decided never to trust him again |
C．forbade hi m to stay alone overnight |
| D．arranged him to stay at home. |
| A．parents don’t trust their child as they should |
| B．defendants are usually proved not guilty in court |
| C．parents have too much trust in their child |
| D．some children are founded guilty in court |
| A．parents shouldn’t punish their children even if they lie |
| B．it is not easy to deal with the problem of lying as parents |
| C．there are effective ways to prevent children from lying |
| D．children will stop telling lies as they grow up |
als concluded on Monday. Some 5,000 birds mysteriously fe
ll from the sky in Beebe, Arkansas after dark on New Year’s Eve. “The birds suffered from acute physical injuries leading to internal hemorrhage（大量出血） and death. There was no sign of infectious disease,” the Arkansas Game and Fish Commission said in a statement. The birds were otherwise healthy, it said.One theory is that birds were frightened by New Year"s fireworks and flew into buildings or other objects. “Loud noises were reported shortly before the birds began to fall from the sky,” the statement said, adding that blackbirds have poor night vision and seldom fly at night.
Another theory was that severe weather such as lightning accounted for the loud noises but this was discounted because the violent weather had already left the area. “We’re leaning more toward a stress event," said Arkansas Game and Fish Commission spokesman Keith Stephens.
The commission also is trying to determine what
caused the deaths of up to 100,000 fish over a 20-mile stretch of the Arkansas River near a dam in Ozark, 125 miles west of Beebe. The fish were discovered on December 30. Stephens said the commission expected results on the fish tests in probably a month. Since almost all the fish were one species -- bottom-feeding drum, Stephens said, the test was very important. Stephens also said: “The events do not appear related.” Both that section of the river and the air at the site of the bird deaths were tested for toxins(毒素). Beebe is a town of about 4,500 people located 30 miles northeast of the state capital. 小题1:What is NOT the probable reason why the dead red-winged blackbirds fell from the sky?
| A．Internal hemorrhage | B．Fireworks |
| C．Lightning weather | D．Murder |
| A．not to reduce cost | B．not to believe |
| C．to make up a part | D．to explain mystery |
| A．cold weather | B．poor management |
| C．disease | D．lack of food |
| A．analyzing causes | B．making comparisons |
| C．examining differences | D．following the time order |
