Adult butterflies use their senses of sight, touch, hearing, smell, and taste to survive in the world, find food and mates, lay eggs in an appropriate place, migrate, and avoid hungry predators.

Sight

Butterflies have large, compound (multifaceted) eyes, which allow them to see in all directions without turning their heads. Like most insects, butterflies are very nearsighted, so they are more attracted to a large stand of flowers rather than individual plants. Butterflies do not "see" colors such as red, green, and yellow, but sense polarized（偏振的） light, which indicates the direction the sun is shining, as well as ultraviolet light, which is present on many flowers and guides butterflies to nectar （花蜜）sources.

Smell

Butterflies have a very well-developed sense of smell, but it's not in their nose (since they don't have one). Sense receptors located in their antennae, feet, and many other parts of the body help butterflies find food (usually flower nectar), and mates (the female smells the male's pheromones).

Taste

Butterfly's feet have sense organs that can taste the sugar in nectar, letting the butterfly know if something is good to eat or not. Some females also taste host plants in order to find appropriate places to lay their eggs. Adult butterflies and moths feed using a proboscis, a long, coiled tube. Butterflies force blood into the tube to straighten it out, allowing them to feed. Butterflies get all their food from this tube.

Hearing

Butterflies don't have ears. Instead they "hear" sounds through their wings by sensing changes in sound vibrations.

Butterflies may possess senses we don't even know about yet because their anatomy is very different than ours, and therefore difficult to understand when perceived through our own human senses.

1.From the passage we can know that butterflies can see_____

A. thing behind them               B. thing in the distance

C. most bright colors               D. flower nectar from a distance

2. Butterflies can easily find food resources by using their______.

A. sense organs of sight and smell     B. sense organs of sight and taste

C. sense organs of smell and hearing   D. sense organs of smell and taste

3. How do butterflies feed themselves?

A. by using their feet                B. by using a tube.

C. by using sense receptors           D. by using their wings.

4.What is the passage mainly about?

A. The food sources of butterflies.     B. The habits of butterflies.

Andy lived high in the Rocky Mountains. He hunted wild animals there and he also took other men to hunt, which was his work.

One day a letter brought Andy a new job. This job changed both his feeling about animals and his way of hunting. The letter said, “I want to write a story about bighorn sheep（大角羊）． I need pictures to go with my story. Will you get pictures of the sheep for me?"

Andy's two sons wanted their father to take the job. "We will help you!” they said. Bighorn sheep are very wild. Andy knew it would be hard to get their pictures. “But why not try?" they said.

For days, Andy and his sons tried to get their pictures, They did not want the sheep to hear them or see them, so they walked softly. They hid behind rocks, but the sheep always ran away.

Then one day, Andy and his sons walked around a big rock. They met some sheep face to face, but they didn't run. "Now I know why the sheep run away," Andy said. "They run because we come up behind them. From now on, we will stay where they can see us."

The next day; Andy saw some sheep right out in the open. He and his sons walked toward them. They did not try to hide, and they did walk slowly. They knew that any fast move would frighten them away．

"Don't look direct at the sheep," Andy said. "Wild animals do not like to be looked at. They will run away. " They looked off to this side and to that side, and they walked closer and closer. And soon they were close enough to get good clear pictures.

Animals seem to have the sense to eat when they are hungry and they do not eat more than their bodies need．It has been demonstrated（证明）that rats will, when given a choice over a period of time, prefer water with vitamins(维生素) to water without vitamins even though there is no difference in taste or smell between the two water bottles．When a fragrant（香的）flavor（作料）was added to the vitamin-enriched water, the rats did seem to prefer it and kept drinking it ,even after the vitamins were switched to the clear water．In time, however, they broke the habit and went back to where the necessary vitamins were．

In a classic experiment, babies of 6 to 12 months old were placed in a cafeteria（自助） feeding arrangement, with a wide selection of baby food before them．They were given whatever food they pointed to or appeared interested in．We are told that at first they showed some unusual eating patterns, but that over a period of time they managed to select well-balanced diet．

So, in choosing food, rats and babies do seem to know and act on what's best for them．Apparently, there is a kind of “body wisdom”, which humans soon lose．Most of us do not eat as wisely as we could．Many of our food preferences are culturally determined and influenced by long-formed habits．Some people eat fox, dog and blackbirds, while we eat cows and pigs．So what people eat and how much they eat seems to be greatly influenced by what is going on around them．

1.In the experiment on rats, a fragrant flavor was added to the rats’ drinking water to _____________ .

A．encourage rats to drink vitamins-enriched water

B．test whether rats know which drink is good for them

C．find out rats’ preference in flavor

D．demonstrate the vitamins are tasteless

2.According to the passage ,adults eating habits differ from those of babies because_________．

A．adults know better than babies what kind of food are good for their health

B．adults usually cannot resist the temptation of various delicious foods

C．adults have more choices of food than babies in eating patterns

D．adults' eating habits are closely related to the social and cultural customs

3.The author implied in the passage that most of us_________．

A．eat a balanced diet

B．choose the food that is of nutrition

C．have the habits influenced by the surroundings

D．like to eat the food with a fragrant flavor．

4.As far as their eating habits are concerned, babies and rats are similar in that_________．

A．both prefer flavored food and drink

B．both have the wisdom to choose a balanced diet

C．both have the same eating patterns

D．both develop a taste for the same kinds of flavors

As the air is being polluted，many kinds of wild animals are________.

高三英语单项填空中等难度题查看答案及解析

Birds are the only animals with feathers, although some other animals, such as insects and bats, also have wings．Nearly all birds can fly, and even flightless birds, such as ostriches （鸵鸟）, penguins, evolved from flying ancestors．

Birds are found worldwide in many habitats．They can fly over some of the highest mountains on earth as well as both of the earth’s poles, dive through water to depths of more than 250m, and occupy habitats with the most extreme climates on the planet, including arctic tundra （冻土地带） and the Sahara Desert．Certain kinds of seabirds are commonly seen over the open ocean thousands of kilometers from the nearest land, but all birds must come ashore to raise their young．

Highly developed animals, birds are sensitive and responsive, colorful and graceful, with habits that excite interest and inquiry．People have long been fascinated by birds, in part because birds are found in the same habitats in which humans live．And like people, most species of birds are active during daylight hours．Humans find inspiration in birds’ capacity for flight and in their musical calls．Humans also find birds useful---their flesh and eggs for food, their feathers for warmth, and their companionship．Perhaps a key basis for our friendliness with birds is the similarity of our sensory worlds: Both birds and humans rely more heavily on hearing and color vision than on smell．Birds are useful indicators of the quality of the environment, because the health of bird populations mirrors the health of our environment．The rapid decline in birds populations and the accelerating extinction rates of birds in the world’s forests, grassland, wetlands, and islands are therefore reasons for great concern．

1.Which of the following would be the best title of the text?

A．Animals with Feathers and Wings

Our friendliness with birds

C．An introduction to Birds

D．Bird’s life

2.What does the second paragraph mainly tell us ?

A．Bird’s friendship              Bird’s habitats

C．Bird’s raising                 D．Bird’s environment

3.Which of following is NOT true according to the passage ?

A．Bird’s flying abilities and musical calls inspire humans greatly．

Birds live in the same surroundings in which humans live．

C．Both birds and humans rely more heavily on hearing and smell than on color vision．

D．Bird’s flesh and eggs for food, bird’s feathers for warmth, and their companionship are useful to us．

4.From the text it may imply but NOT state that __________．

A．the environment is being damaged seriously

if you want to raise birds, you should pay attention to environment

C．the environment affects the human beings

D．bird populations decrease rapidly

Animals are not always animals. Some of them will try to cheat or cow some others in the way the human beings often do. Here is a fairy tale from Aesop for you to enjoy.

An eagle（鹰）made her nest at the top of a high tree while a cat, having found a convenient hole, moved into the middle of the trunk, and at the same time a wild pig, with her young took shelter in a hollow at its foot. The cat then decided to make all serve her in her wise way.

To carry out her design, she climbed to the nest of the eagle, saying, "Destruction is preparing for you and for me too, unfortunately. The wild pig, whom you see daily digging up the earth, wishes to uproot the tree, so she may on its fall seize our families as food for her young."

Having thus frightened the eagle out of her senses, she crept down to the cave of the pig, saying, "Your children are in great danger, for as soon as you go out to find food, the eagle is prepared to jump upon one of your little pigs."

Having filled these fears into the pig, she went and pretended to hide herself in the hollow of the tree. When night came she went out silently and obtained food for herself and her children, but pretending to be afraid, she kept a lookout all through the day. Meanwhile, the eagle, full of fear of the pig, sat still on the branches, and the pig, terrified by the eagle, did not dare to go out from her cave. Thus they both, along with their families, starved from hunger, and afforded good food for the cat and her children.

1.What was the eagle afraid of?

A. Her home would be destroyed.
