Ants have outsmarted me on more than one occasion.In particular, there was a weekend

last summer when an ant scientist was a guest at our cottage.I boasted to my naturalist friend that I could store food in an open container for a whole week and keep it safely out of the reach of house ants.Sunday night the experiment got under way.I put a large wooden tub on the kitchen floor of our cottage.After filling it to about the three-quarters mark with water, I placed a high wooden stand in the middle of it.On top of the stool, I put a saucer containing the bait: three or four pieces of rich chocolate candy.Then I painted a wide band of very slow-drying glue around the outside of the wooden tub.With that, I stood back and admired my ant trap, fully confident that the bait would be untouched upon my return to the cottage the following weekend.When my naturalist friend and I entered the cottage just six days later, ants were swarming over the bait! Here's how they put me to shame.Single files of ants had marched head-on into the band of glue around the outside of the wooden tub.A handful of them had endured martyrdom, for they had embedded themselves end to end, and made causeways of their bodies.The tempting bait on top of the stool must have caused the little creatures to use their brains to the limit.Ants hate water, but they had been courageous enough to build a highway across the stretch of water to a leg of the stool.They had assembled tiny pieces of grass and bits of wood no longer than a thirty-second of an inch, and had glued them together with saliva until their bridge extended from shore to island.Once they reached the leg of the wooden stool, traffic was almost all one way toward the chocolate bait.But there were some show-off fellows around, too; they were doing things which ants have been known to do very rarely.We noticed that a half dozen or so were walking across the ceiling, and when they came directly over the bait they let themselves fall squarely into the middle of their merry brothers.It is little wonder that I have been on the trail of ants ever since, trying to trip them up or at least learn some of the special tactics that they use.

阅读理解:阅读下面的短文,根据文章内容从A、B、C三个选项中选出一个最佳选项。

There are more ants than any other kinds of land animals in the world. They range from 0.1 to 1 inch long and are usually yellow, brown, red, or black. Ants live in societies in which they depend on one another. The societies are not all exactly the same because there are ants of very many kinds. But in general, each kind has ants of three main typesA、queens, males, and workers.

The ants have a good many enemies. They include birds, bears and ant eaters of various kinds. In some cases other ants are their worst enemies, as man’s enemy is man. In some parts of the world, red ants march in large armies to attack the homes of black ants. Some of them succeed in getting inside of the tunnels of black ants, whose entrances have been blocked. They try to carry the black ant babies away. The black ants do all they can to prevent that. They send their biggest soldiers into action. Very many of the red ants soldiers are killed but some escape with babies belonging to the black ants. The red ants take the babies home and bring them up. They become the only workers for the red ants.

Ants as a group are beneficial to humans. Their tunnels mix and soften the soil, in some places replacing the activity of earthworms. Some of ants are harmful to humans. For example, the fire ant, which has a painful bite, is a serious pest to humans and domestic animals in many parts of the world.

1. Which kind of ants is not regarded as the main types of ants in general? {A、B、C}

B. Each ant depends upon itself in the society.

C. Ants are useful to human on some conditions.

5. The main purpose of the passage is to {A、B、C}.

DThere are an extremely large number of ants worldwide. Each individual (个体的) ant hard

D

There are an extremely large number of ants worldwide. Each individual (个体的) ant hardly weigh anything, but put together they weigh roughly the same as all of mankind. They also live nearly everywhere, except on frozen mountain tops and around the poles. For animals their size, ants have been astonishingly successful, largely due to their wonderful social behavior.

In colonies (群体) that range in size from a few hundred to tens of millions, they organize their lives with a clear division of labor. Even more amazing is how they achieve this level of organization. Where we use sound and sight to communicate, ants depend primarily on pheromone (外激素), chemicals sent out by individuals and smelled or tasted by fellow members of their colony. When an ant finds food, it produces a pheromone that will lead others straight to where the food is. When an individual ant comes under attack or is dying, it sends out an alarm pheromone to warn the colony to prepare for a conflict as a defense unit.

In fact, when it comes to the art of war, ants have no equal. They are completely fearless and will readily take on a creature much larger than themselves, attacking in large groups and overcoming their target. Such is their devotion to the common good of the colony that not only soldier ants but also worker ants will sacrifice their lives to help defeat an enemy.

Behaving in this selfless and devoted manner, these little creatures have survived on Earth, for more than 140 million years, far longer than dinosaurs. Because they think as one, they have a collective (集体的) intelligence greater than you would expect from its individual parts.

根据材料回答68-71题。 We can learn from the passage that ants are ____________.

A.not willing to share food

B.not found around the poles

C.more successful than all other animals

D.too many to achieve any level of organization

Night of the Living Ants When an ant dies,other ants move the dead insect out of the nest.

Night of the Living Ants

When an ant dies,other ants move the dead insect out of the nest.This behavior. is interesting to scientists,who wonder how ants know for sure-and so soon-that another ant is dead.

Dong-Hwan Choe,a scientist at the University of California,found that Argentine ants have a chemical on the outside of their bodies that signals to other ants,“I’m dead-take me away.”

But there's a twist to Choe's discovery.Choe says that the living ants-not just the dead ones -have this death chemical.In other words,while an ant crawls around,perhaps in a picnic or home,it's telling other ants that it's dead.

What keeps ants from hauling away the living dead?Choe found that Argentine ants have two additional chemicals on their bodies,and these tell nearby ants something like,“Wait-I'm not dead yet.” So Choe's research turned up two sets of chemical signals in ants:one says,“I'm dead,”the other set says,“I'm not dead yet.”

Other scientists have tried to figure out how ants know when another ant is dead.If an ant is knocked unconscious,other ants leave it alone until it wakes up.That means ants know that unmoving ants can still be alive.

Choe suspects that when an Argentine ant dies.the chemical that says“Wait-I'm not dead yet” quickly goes away.Once that chemical is gone,only the one that says“I'm dead”is left.“It's because the dead ant no longer smells like a living ant that it gets carried to the graveyard(墓地),not because its body releases new,unique chemicals after death,”said Choe.When other ants detect the“dead”chemical without the“not dead yet”chemical,they haul away the body.This was Choe's hypothesis(假设).

To test his hypothesis,Choe and his team put different chemicals on Argentine ant pupae(蛹). When the scientists used the“I'm dead”chemical,other ants quickly hauled the treated pupae away. When the scientists used the“Wait-I'm not dead yet”chemical,other ants left the treated pupae alone. Choe believes this behavior. shows that the“not dead yet”chemical overrides(优胜于)the“dead”chemical when picked up by adult ants.And that when an ant dies,the“not dead yet”chemical fades away. Other nearby ants then detect the remaining“dead”chemical and remove the body from the nest.

The phrase“this death chemical”in paragraph 3 refers to

A.the chemical that contains poison.

B.the chemical that announces death.

C.the chemical that prevents death.

D.the chemical that causes death.

How certain ants have come to cultivate fungi as their sole diet has been a subject of
a good deal of speculation. Perhaps the most reasonable explanation is as follows. Ants have a pouch in the bottom of their mouths called the infrabuccal pocket. Any solid food they eat goes into this pocket, where the soluble substances are dissolved. The liquid solution is swallowed, but the solids are screened out and accumulate in the pouch. Being fastidious animals, much of the ants leisure time is spent in combing bits of dirt and debris off their bodies. This grooming is accomplished by means of fine combs on their forelegs. The combs, in turn, are cleaned by passing them neatly through the mouth. So the particles of dust, dirt, and other solid matter so acquired end up in the infrabuccal pocket. In time the pouch becomes filled, and the contents are thrown out, much as a baseball player or cowboy may dispose of a spent chew of tobacco.

Before such disposal, the pouch is moist and warm, and it is highly likely that among its contents would be a great variety if microscopic fungus spores, or seeds. Although most if the spores perish in the pouch, others thrive, When the waste material is deposited in the nest, fungi grow and cover the material. Since certain kinds of fungi are high in food value, and since the ants can subsist on them, it is not surprising that some of the more clever kinds of ants should have learned to cultivate them.

(1).What is the purpose of the infrabuccal pocket in ants?

选项格式A、To digest solid foods

B、To collect debris

C、To liquefy solids

D、To hold soluble substances

(2).According to the passage, ants constantly groom themselves because

A、they have a strong desire to be clean

B、dirt in their bodies prevents them moving quickly

C、they have very little to occupy their time

D、it is a type of social ritual

(3).What do ants do to clean out their infrabuccal pockets?

选项格式A、Swallow the accumulated debris

B、Turn the pockets inside out

C、Spit out the waste material

D、Remove the pockets for cleaning

(4).According to the passage, the spores in the infrabuccal poclets

选项格式A、mainly die

B、never survive

C、dry up

D、mostly thrive

(5).We understand from the passage that when the infrabuccal pockets are cleaned out

选项格式A、the waste material is made into the nests

B、spores in the material develop into fungi

C、the material is consumed by fungi

D、seeds fall to the ground and start to cover the material

第9题

It is a curious phenomenon of nature that only two species practice the art of war -- men
and ants, both of which, significantly, maintain complex social organizations. This does not mean that only men and ants engage in the murder of their own kind. Many animals of the same species kill each other, but only men and ants have practiced the science of organized destruction, employing their massed numbers in violent combat and relying on strategy and tactics to meet developing situations or to take advantage of the weaknesses in the strategy and tactics of the other side.

While all entomologists (昆虫学家) are all agreed that war is instinctive with ants, it is encouraging to note that not all anthropologists (人类学家) and biologists are agreed that war is instinctive with men. Those who lean on experience, of course, find everything in man's history to indicate that war is locked up within his nature. But a broader and more generous, certainly more philosophical, view is held by those scientists who claim that evidence of a war instinct in men is incomplete and misleading, and that man does have within him the power of abolishing (废除) war. Julian Huxley, the English biologist, draws a sharp distinction between human nature and expression of human nature. Thus war is not a reflection but an expression of man's nature.

Moreover, the expression may change, as the factors which lead to war may change. "In men, as in ants, war in any serious sense is bound up with the existence of accumulations of property to fight about... As for human nature, it contains no specific war instinct, as does the nature of harvester ants. There is in man's makeup a general aggressive tendency, but this, like all other human urges, is not a specific and unvarying instinct; it can be molded (塑造) into the most varied forms."

But even if this gives us a reassuring answer to the question -- is war inevitable because of man's nature? -- it still leaves unanswered the question concerning the causes leading up to war. The expression of man's nature will continue to be warlike if the same conditions are continued that have prompted warlike expressions in him in the past. And since man's survival on earth is now absolutely dependent on his ability to avoid a new war, he is faced with the so-far insoluble problem of eliminating those causes.

Which of the following is NOT TRUE according to the passage?

A.There are different factors which may lead to war.

B.War has been rooted in and will develop with human history.

C.Both men and ants maintain complex social organizations.

D.Only men and ants have developed and practiced the art of war.
