THE REMARKABLE ROCKS area must-see on Kangaroo Island
accessible by air and ferry from the Australian mainland
Hop on new Kangaroo Island trail
for five-day adventure
It sounds like an amusement park.Or a portion of a zoo reserved for marsupials(有袋动物). But Kangaroo Island(KI), 30 minutes by air from Adelaide in South Australia, is just the opposite. Much of the island remained inaccessible to visitors until this year.Opened to the public in May, the Kangaroo Island Wilderness Trail, a nearly 38-mile, fie-day hike, ushers adventurous trekkers on a botanically distinctive immersion into the islands' south-west side.
Footers can expect to walk roughly four to seven hours a day, passing colorful flower, splendid sugar gum tees and massive native plant life. In this timeless setting, they'll likely sport kangaroos, goanna lizards and spiny echidna. From cliff rims， they'll overlook the Southern Ocean， where sharks lurk and schools of salmon cluster in flower like, protective formations.
The trial includes 4 camping areas,each outfitted with 24 tent platforms :12 for self-guided walkers and 12 for tour operators,who also can arrange options off the trail.
Independent trekkers pay about$124to do the walk; the cost includes the parking at the Flinders Chase visitor center ,and a trail guide and map.
KI is accessible both by air and by ferry ;www.tourkangarooisland. com.au

Sea urchins (海胆) are small creatures, but what’s really remarkable about them is that they eat anything that happens to float by. They have really sharp teeth they use to rid rocks of algae (海澡), which makes them pretty valuable especially in places like Hawaii where algae are threatening the coral reefs. In the summer of 2019, 500,000 of them were used to deal with the algae.
The problem started when non-native algae were introduced to the ecosystem of Kane’ohe Bay in the 1970s. Because they had no enemies, they ended up taking over the bay, according to the National Marine Fisheries Service (NMFS). The algae blocked sunlight from reaching the coral, which in turn affected the local fish because they changed the chemistry of the water.
That's when the NMFS turned to sea urchins that loved to devour the algae. But they had to grow to the size of a cherry tomato before they could be used. Since 2011, sea urchins have been grown and used to handle the algae problem. Some of the funds are available due to an unfortunate incident.
In 2005, a ship was grounded on a shallow reef near Kane’ohe Bay. When the ship was removed, 20 acres of reefs have been damaged. When there is environmental damage, the NMFS and other agencies receive funds from the wrongdoers and the funds are used to restore the damage. Some funds were spent on other projects like the sea urchins.When they are large enough, divers carefully place them on the reef.
Algae isn’t the only thing that threatens the coral reefs. Climate change and the effects of fishing and tourism in the area also endanger the coral reefs. But turning to sea urchins instead of man-made solutions seems like the best way to go.
1.Why are sea urchins regarded as outstanding creatures?
A.They are tiny but have teeth. B.They can keep the ocean clean.
C.They are useful in removing algae. D.They grow on coral reefs with algae.
2.What happened after non-native algae arrived at Kane’ohe Bay?
A.They helped the coral reefs to survive. B.They spread to every corner of the bay.
C.They didn’t fit in with the new surroundings. D.They fought against other species to get food.
3.What does the underlined word “devour” in paragraph 3 mean?
A.Eat. B.Block. C.Tease. D.Attract.
4.What does the author suggest doing to save coral reefs?
A.Relying on humans’ solutions. B.Banning fishing and tourism.
C.Employing divers to handle algae. D.Letting nature take care of nature.

A remarkable variety of insects live on this planet. Insects have survived on earth for more than 300 million years, and may possess the ability to survive for millions more.
Insects can be found almost everywhere—on the highest mountains, in the cold South Pole and in bubbling hot springs. They dig through the ground, jump and sing in the trees, and run and dance in the air. They come in many different colors and various shapes. Insects are extremely useful to humans,pollinating (授粉) our crops as well as flowers in meadows,forests, deserts and other areas. But some insects, such as mosquitoes and fleas, can transmit disease.
There are many reasons why insects are so successful at surviving. Their amazing ability to adapt permits them to live in extreme ranges of temperatures and environments. They can survive on a wide range of natural and artificial foods - paint, books, grain, plants and animals. Because they are small, they can hide in tiny spaces.
A strong, hard but flexible shell covers their soft organs and is resistant to chemicals, water and physical impact. Their wings give them the option of flying away from dangerous situations or toward food or mates. Also, insects have an enormous reproductive capacity: An African ant queen can lay as many as 43,000 eggs a day.
Another reason for their success is the strategy of protective color. An insect may be right before our eyes, but nearly invisible because it is cleverly disguised (伪装) like a green leaf, lump of brown soil, a seed or some other natural object. Some insects use bright, bold colors to send warning signals that they taste bad. Others have wing patterns that look like the eyes of a huge predator, confusing their enemies.
1.What does the underlined word “transmit” in Paragraph 2 mean?
A.cure. B.catch.
C.prevent. D.spread.
2.How can the insects protect themselves from chemicals?
A.Have a strong shell. B.Fly away when necessary.
C.Hide in tiny spaces. D.Change colors or shapes.
3.Why do some insects disguise like natural objects?
A.To look bad—tasting. B.To send warning signals.
C.To avoid being discovered. D.To frighten away their enemies.
4.What’s the main idea of this text?
A.How insects survive in different places.
B.Why insects can survive so successfully.
C.What insects can do to the environment.
D.Where insects can be found in quantity.

Researchers recently discovered some unusual behavior in chimps living in the forests of West Africa. An adult male in the wild would pick up a rock, throw it at a tree while yelling and then run away. Although researchers aren't certain why, they make a guess: The chimps seem to prefer trees that create longer-lasting sounds when struck.
A team of researchers from Germany first discovered this behavior three years ago. Because the actions appeared to be localized, the researchers suggested the purpose was a local tradition and was likely part of some sort of ritual(仪式), Phys. org reports. But they weren't sure what purpose the ritual served.
So the group desired to carry out more experiments to determine why the chimps were so interested in throwing rocks at trees. This time around, they went to the same areas but set up microphones to capture(捕捉) the sounds of the stones as they were thrown.
Researchers analyzed all the recordings and found that the chimps tended to prefer throwing rocks at trees that made lower, longer-lasting sounds. Often these were trees that had exposed roots.
In their findings, published in Biology Letters, the researchers write that “low-frequency sounds travel further in the environment and are better suited for long-distance communication”.
If chimps tried to communicate. it would be more effective for them to strike the trees or choose the ones that made the loudest noises when struck. Because the researchers saw chimps stick to the same trees and never choose new ones, the location could be a factor. Researcher Ammie Kalan tells Science that maybe the locations of the trees have something to do with nearby resources like food and water, and that the sound is a signal to others where to find them.
1.How did the researchers feel about the chimps behavior from the first two paragraphs?
A.Doubtful B.Excited C.Disappointed D.Frightened.

A.They tried to make long-lasting sounds.
B.They recorded the sounds from the stricken（受...侵袭的） trees.

3.What does Ammie Kalan think of the chimps' behavior?
A.It is a good way of seeking food. B.It is a means of communication.
C.It is a natural response to food. D.It is a symbol of their growth.
4.What is the text mainly about?
A.How the chimps produce sounds.
B.The chimps’ habit of throwing rocks.
C.Why the chimps like to throw rocks at trees.
D.Chimps often throw rocks at different kinds of trees.
