Over the years I've been teaching children about a simple but powerful concept -- the ant philosophy (哲学).I think everybody should study ants.
They have an amazing four-part philosophy, and here is the first part: ants never quit. That's a good philosophy. If they're headed somewhere and you try to stop them; they'll look for another way.
They'll climb over, they'll climb under, and they'll climb around. They keep looking for another way. What a neat philosophy, to never quit looking for a way to get where you're supposed to go.
Second, ants think winter all summer. That's an important viewpoint. You can't be so naive ( 天真的) as to think summer will last forever. So ants are gathering in their winter food in the middle of summer.
An ancient story says, "Don't build your house on the sand in the summer. " Why do we need that advice.'? Because it is important to be realistic. In the summer, you've got to think storm. You've got to think rocks as you enjoy the sand and sun. Think ahead.
The third part of the ant philosophy is that ants think summer all winter. That is so important. During the winter, ants remind themselves, "This won't last long ; we'll soon be out of here. " And on the first warm day, the ants are out. If it turns cold again, they'll dive back down, but then they come out on the first warm day. They can't wait to get out.
And here's the last part of the ant-philosophy. How much will an ant gather during the summer to prepare for the winter? All he possibly can. What an incredible philosophy, the "all-you-possibly-can" philosophy.
Wow, what a great seminar to attend -- the ant seminar. Never give up, look ahead, stay positive and do all you can.If you try to stop ants going forward, they will
| A．climb over your head | B．quit looking for a way |
| C．search for another way | D．keep climbing around |
What is the second philosophy of ants?
| A．Think winter all summer. | B．Always be realistic. |
| C．Never become lazy in summer. | D．Always look ahead. |
Which of the following can best describe the third part of the ant philosophy?
| A．Always stay positive. | B．Always remind yourself. |
| C．Always think summer. | D．Always be hardworking. |
We can learn from the last part of the ant philosophy that we should
| A．never stop gathering food in the summer | B．always get prepared for the winter |
| C．gather as much as possible for the future | D．do whatever we can for the future |
Which of the following is the best title for the passage?
| A．The Concept of Ants | B．The Ant Philosophy |
| C．Never Give up | D．Do All You Can |
Like all animal species, plant species must spread their off-spring to suitable areas where they can grow and pass on their parents' genes. Young animals generally spread by walking or flying. Because plants don't have that ability, they must somehow hitchhike(搭顺风车). Some plant seeds scatter by blowing in the wind or floating on water. Many other plant species, though, trick an animal into carrying their seeds. How do they do this? They enclose the seeds within a tasty fruit and advertise the fruit's ripeness by its colour or smell. The hungry animal collects and swallows the fruit, walks or flies off, and later spits out the seeds somewhere far from its parent tree. Seeds can thereby be carried for thousands of miles. It may surprise you to learn that plant seeds can resist digestion. In fact, some seeds actually require passage through an animal's body before they can grow.
Wild strawberries offer a good example of hitchhiking tactics. When strawberry seeds are still young and not yet ready to be planted, the surrounding fruit is green, sour and hard. When the seeds finally mature, the berries turn red, sweet, and tender. The change in the berries'colour serves as a signal to birds which then eat the strawberries, fly off, and eventually spit out the seeds.
Naturally, strawberry plants didn't set out with a conscious intention of attracting birds only when their seeds were ready to be dispersed . Nor did birds set out with the intent of planting strawberries. Rather, strawberry plants evolved through natural selection. The sweeter and redder the final strawberry, the more birds spread its ripe seeds ； the greener and more sour the young strawberry, the fewer birds destroyed the seeds by eating berries before the seeds were ready. What does the underlined word "dispersed" in the third para-graph mean?
| A．Spread. | B．Eaten. | C．Born. | D．Planted. |
For plants, which of the following is NOT a way of spreading their offspring to suitable areas?
| A．Hitchhiking. |
| B．Blowing in the wind. |
| C．Floating on water. |
| D．Tracking an animal. |
Which strategy does the example of wild strawberries describe?
| A．The conscious intent of attracting birds. |
| B．Spreading by walking. |
| C．Spreading by flying. |
| D．The strategy of taking a lift. |
Why does the author describe how strawberry seeds are spread?
| A．To show plants are good at adapting to the environment. |
| B．To show strawberry's special way. |
| C．To show the plant has different ways of spreading seeds. |
| D．To show the mystery of plant. |
What's the passage mainly about?
| A．How animals disperse offspring. |
| B．How plants disperse their offspring. |
| C．Plant evolution. |
| D．Plants'hitchhiking on animals. |
UCLA scientists report for the first time on the only known frog species that can communicate using purely ultrasonic(超声）calls, whose frequencies are too high to be heard by humans. Known as Huia cavitympanum, the frog lives only on the Southeast Asian island of Bomeo(婆罗洲）.
Ultrasounds are high-pitched sounds more than 20 kilohertz(kHz) in frequency, which exceeds the upper limit of sounds detectable by humans and is far higher than the 5 to 8 kHz frequencies most amphibians (两栖动物)，reptiles and birds are capable of hearing or producing. Key parts of the ear must be specially adapted to detect ultrasounds.
The frogs can hear sounds up to 38 kilohertz, the highest frequency that any amphibian species has been known to hear, the scientists report. Humans can hear up to about 20 kHz and typically talk at 2 or 3 kHz.
While most of the more than 5，000 frog species worldwide have eardrums that are flat on the side of the head, Huia cavitympanum has eardrums recessed in the side of the skull, similar to mammals.
Peter Narins, UCLA distinguished professor of physiological science and of ecology and evolutionary biology, and Victoria Arch, a UCLA graduate student in ecology and evolutionary biology, spent several nights in the remote area where the frogs live.
" We had very little information suggesting that they would be in this location，" said Arch, lead author of the study. " We found them our first night out. "
The study was published on April 29 in the online journal PLOS ONE, a publication of the Public Library of Science, and is available at

The black robin (知更鸟）is one of the world's rarest birds. It is a small, wild bird and it lives only on the island of Little Mange-re, off the coast of New Zealand. In 1967 there were about fifty black robins there ； in 1977 there were fewer than ten. These are the only black/robins left in the world. The island has many other birds, of course, of different kinds, large and small, and they seem to multiply (繁殖）very happily.
Energetic steps are being taken to preserve the black robin—to guard those appeal for money has been made. The idea is to buy another island nearby as a special home, a "reserve"，for threatened wildlife, including black robins. The organizers say that Little Man-gere should then be restocked (再储存）with the robin's food—it eats only one kind of seed—and so renewed for it. Thousands of the required plants are at present being cultivated (耕种）in New Zealand. The public appeal is aimed at improving the conscience of mankind, so that the wild black robin will not die out and disappear from the earth in our time at least.
In the earth's long, long past, hundreds of kinds of creature have evolved (进化），risen to a degree of success and died out. In the long, long future there will be many new and different forms of life. Those creatures that adapt themselves successfully to what the earth offers will survive for a long time. Those that fail to meet the challenges will disappear early. That is Nature's proven method of operation.
The rule of selection " the survival of the fittest" is the one by which man has himself arrived on the scene.
Life seems to have grown too tough for black robins. The black robin is dying out mainly because __________.
| A．people have been very careless about its survival |
| B．its only food is becoming exhausted(耗尽)on Little Mangere |

| D．the appeal for money has come at the wrong time |
The writer's attitude towards the protection of the black robins is __________
| A．active | B．passive |
| C．indifferent | D．pessimistic |
The success of other small birds on Little Mangere shows that __________.
| A．the island cannot have very much food left |
| B．something has to die out, and they can't all be winners |
| C．the big birds have all been attacking the black robin |
| D．the robin has failed to meet the challenges of life |
As regard selection and survival, the decisive factor seems to be __________
| A．the ability to adapt to changed or changing conditions |
| B．the number of wildlife reserves that are available |
| C．the concern and generosity of the public |
| D．the size of the home, or the amount of space one has to live in |
The evidence seems to suggest that __________
| A．it is a disaster for everyone when one kind of bird dies out |
| B．all creatures are concerned about the survival of others |
| C．nature expects and accepts the dying out of weaker breeds |
| D．man is to blame when such a thing happens |
Several years ago I worked in an office, which I had a locust tree growing outside the window. It had grown into a tall tree and must have been there for a long time. The tree blocked the view and made the office seem dull, unfortunately this happened to be the room assigned to me and I was depressed by it for quite some time.
When the first spring came, everything was green except the locust tree. Secretly, I was very happy because I had thought it had died.
One morning when I opened the window for fresh air, I unexpectedly smelt a familiar sweet scent floating into my office but I couldn't name it. Suddenly, I realized it was the locust tree ！ The tree that I thought dead was blossoming in full glory.
From then on, I usually came to the office very early to see dew forming on the locust tree blossoms and every year was eager to see spring again.
