The Peppered Moth, a kind of insect, is found in England. It is light brown in color and likes to settle on trees which are also light brown. This makes the moth difficult to be seen and birds are less likely to notice and eat it.
But with the development of industry, smoke from factories began to reach the trees where the moth settled. It made the trees blacker. Then something very strange took place: in industrial areas, the Peppered Moth began to change color. It became darker as well. Although the change took several years, some scientists soon noticed that newly-born moths were a little darker than usual.
A scientist called Kettle Well decided to make a careful study of this. He marked some of the light moths and some of the darker ones, and set them free in the woods near Birmingham, an industrial city. Later he retarget as many the marked moths as possible ( The result was given in the chart ).
Kettle Well’s research was done in the early 1950s. Soon afterwards Britain introduced new laws to reduce smoke and factory pollution.
Can you imagine what would happen to the Peppered Moth as the air became cleaner again?
light moths | darker moths | |
Moths set free | 201 | 601 |
Moths recaught | 34 ( 16%) | 206 ( 34%) |
1. The trees where the Peppered Moth settled changed their color because _____________________________.
A. the Peppered Moth changed its color
B. the Peppered Moth couldn’t be easily found on them
C. industry in England developed quickly
D. the smoke from factories polluted them
2. The Peppered Moth began to change its color in industrial areas because _____________________________.
A. it changed its color all the time
B. it was fond of the color of its living place
C. it had to protect itself by doing so
D. it was a special sort of insect
3. From the results of Kettle Well’s research, we can see that _________________.
A. many more of the light moths were killed or eaten
B. more than one-fifth of the light moths escaped being killed
C. three times as many dark moths were kept safe as light ones
D. more dark moths were killed in industrial areas
4. Kettle Well’s work gives us a good example of _________________________.
A. Air Pollution B. Choice of Color C. Laws of Nature D. Changing Insects
5. As the air became cleaner, _________________________.
A. the number of the light moths increased
B. the total number of the light moths remained unchanged
C. more of the darker moths would be recaught
D. the darker moths changed into the light ones before long

Amazing Facts About Elf Owls
Brief Introduction
The elf owl (a kind of owl) is mostly found in the southwestern parts of the United States and Mexico. During the spring and summer seasons, it moves to Arizona and New Mexico. It returns to Mexico for the winter. The elf owl doesn’t build its nest. It lives in tree holes.
Features
The elf owl is a yellow bird. Its wings are dark and about .48-61 centimeters long. Its eyes are bright yellow. Its feet are large. It is the smallest owl of the species. It is about 12.5-14.5 centimeters long. It is also the world’s lightest owl, weighing not more than 40 grams. In general, female elf owls weigh more than male ones.
The female usually lays three eggs at a time. After the young elf owls are born,their mother will feed them with worms(蠕虫) for up to 3-4 weeks. After 10 weeks, the young ones are fully grown and ready to take flight.
Living Habits
The elf owls are not aggressive birds. When danger comes, they will fly away in the other direction, rather than stay and fact the danger or the enemies. Besides flying,the elf owl can also walk and climb like a parrot. The elf owl is most active after dusk,during the night, and just before dawn. It can produce many different kinds of sounds. It can live for 3-6 years in the wild. If they are kept in cages, they can live for 10-14 years. The elf owls are now in danger because of the loss of habitat.

If you look outside, you probably will see some kind of insect. If your first instinct is to kill it, take a moment to think about all of the benefits insects provide to the environment.
Entomologists, scientists who study insects, estimate that there are more than 800,000 species of insects found throughout the world. Only a few hundred of these insects are considered harmful. Mosquitoes, for example, are considered harmful. They bite humans and other animals, and their bites can cause skin pain and spread disease. Desert locusts also are considered harmful because they destroy crops causing billions of dollars in damage each year.
However, the number of helpful insect species far outweighs the number of harmful species. Some insects make up a vital part of the food chain. Many different birds, reptiles, fish and even plants eat insects. There are also about 500 insects that people in various parts of the world eat. These insects are considered delicious food and prized for their high protein, mineral, and vitamin content. Other insects produce valuable commercial products such as silk, wax, and honey.
Of all the insects, perhaps the most important are those that travel from flower to flower and pollinate(授粉) the plants they visit. Agriculture around the world would be very different without the bees, butterflies, moths, flies and wasps that pollinate many crops. In fact, nearly one-third of the food you eat depends on plants that are pollinated by insects!
While it is true that some species of insects harm or annoy us,you should not automatically reach for the bug spray when you come across an insect. You may be destroying one of the hundreds of thousands of insects that provides many benefits to human beings.
1.According to the passage, the most important type of insects are ________.
A.insects that are eaten by birds, reptiles and fish
B.insects that travel around and pollinate plants
C.insects that harm mosquitoes and stop the spread of disease
D.insects that are eaten by people in many countries
2.According to the passage, insects are eaten in some parts of the world because ________.
A.they are nutritious
B.they are available to cook
C.they are easy to breed
D.they are free
3.According to the author, the sentence in the last paragraph “you should not automatically reach for the bug spray.” means ________.
A.you should not keep insects as pets
B.you should not breed insects for their benefit
C.you should not catch insects for pleasure
D.you should not kill insects without thinking
4.The main purpose of this passage is ________.
A.to explain why it is cruel to kill bugs
B.to convince people that insects are nutritious
C.to describe the beneficial contributions of insects
D.to make people aware of endangered insect species

On the island of New Zealand, there is a grasshopper-like species of insect that is found nowhere else on earth. New Zealanders have given it the nickname weta, which is a native Maori word meaning “god of bad looks”. It’s easy to see why anyone would call this insect a bad-looking bug. Most people feel disgusted at the sight of these bulky(笨重的),slow-moving creatures.
Wetas are natural creatures; they come out of their caves and holes only after dark. A gaint weta can grow to over three inches long and weigh as much as 1.5 ounces. Giant wetas can hop up to two feet at a time. Some of them live in trees, and others live in caves. They are very long-lived for insects, and some adult wetas can live as long as two years. Just like their cousins grasshoppers and crickets, wetas are able to “sing” by rubbing their leg parts together, or against their lower bodies.
Most people probably don’t feel sympathy for these endangered creatures, but they do need protecting. The slow and clumsy wetas have been around on the island since the times of the dinosaurs, and have evolved and survived in an environment where they had no enemies until rats came to the island with European immigrants. Since rats love to hunt and eat wetas, the rat population on the island has grown into a real problem for many of the native species that are unaccustomed to its presence, and poses a serious threat to the native weta population.
1..According to the passage, which of the following statements is TRUE?
The weta is a newly discovered insect species.
The Maoris nicknamed themselves “Wetas”.
The Europeans brought wetas to New Zealand.
Wetas are unpleasant to the eye.
2..The strange thing about wetas is that they can produce pleasant sounds by ________.
A. rubbing their body parts
B. moving slowly on the ground
C. hopping up to two feel at a time
D. coming out only at night
3.Which of the following descriptions of wetas is accurate?
A. They are quick in movement.
B. They are decreasing in number.
C. They are very active in the daytime.
D. They have a short lifespan for insects.
4.The underlined word “its” in the last paragraph is the closest in meaning to “_________”.
A. The dinosaur’s B. The weta’s C. The island’s D. The rat’s
5.From which of the following is the passage LEAST likely to be taken?
A. A science magazine. B. A travel guide.
C. A business journal. D. biology textbook.
