1 . Rainforests are home to a rich variety of medicinal plants, food, birds and animals. Can you believe that a single bush(灌木丛)in the Amazon may have more species of ants than the whole of Britain! About 480 varieties of trees may be found in just one hectare of rainforest.
Rainforests are the lungs of the planet-storing vast quantities of carbon dioxide and producing a significant amount of the world's oxygen. Rainforests have their own perfect system for ensuring their own survival; the tall trees make a canopy(树冠层)of branches and leaves which protect themselves, smaller plants, and the forest animals from heavy rain, intense dry heat from the sun and strong winds.
Amazingly, the trees grow in such a way that their leaves and branches, although close together, never actually touch those of another tree. Scientists think this is the plants' way to prevent the spread of any tree diseases and make life more difficult for leaf-eating insects like caterpillars. To survive in the forest, animals must climb, jump or fly across the gaps. The ground floor of the forest is not all tangled leaves and bushes, like in films, but is actually fairly clear. It is where dead leaves turn into food for the trees and other forest life.
They are not called rainforests for nothing! Rainforests can generate 75%of their own rain. At least 80 inches of rain a year is normal-and in some areas there may be as much as 430 inches of rain annually. This is real rain-your umbrella may protect you in a shower, but it won't keep you dry if there is a full rainstorm. In just two hours, streams can rise ten to twenty feet. The humidity(湿气)of large rainforests contributes to the formation of rainclouds that may travel to other countries in need of rain.

5 . A 2020 study in the journal Science concluded that marine heat waves have increased more than 20-fold as a result of climate warming. The authors found that in the first decade after satellites began recording ocean temperatures (i.e., after 1981), there were 27 large marine heat waves, with an average duration of 32 days and an average peak temperature anomaly of 8.5°F; in the 2010s, there were 172, which lasted 48 days on average with an average peak temperature almost 10°F above normal.
Much remains unclear about marine heat waves. For example, explains Nicholas Bond, research scientist at the University of Washington and Washington’s state climatologist, there is the question of why so many persist for weeks or months. “There must be something else going on that helps maintain them,” he says. He notes that one explanation is that as the ocean surface warms, it radiates heat into the atmosphere that prevents cloud cover from forming, exposing the seawater to increased sunlight and further warming.
However, enough is known about marine heat waves for scientists to be gravely concerned about their potential impacts. Of special note is the fact that those impacts can last long after the heat waves have disappeared. After three years of the Blob, the waters of the northeastern Pacific began to cool in 2016; but years later, scientists are still determining the extent to which the region’s ecosystem is likely to return fully to its pre-Blob status. Similarly, notes Scannell, who is a data scientist with Jupiter Intelligence, Inc., following the 2010-11 Western Australia event, “lots of kelp(巨藻) forests died, and it takes literally decades for those ecosystems to bounce back”.
Eric Oliver, a scientist from Dalhousie University in Nova Scotia, Canada, expressed his own opinion about the potential impact of the heat waves in tropical waters. “I think that’s really a tough issue,” he says. Life in the tropics, he notes, is adapted to “quite a narrow range of temperatures. So that’s where things can get really messy. We can have complete shifts in tropical systems.”

6 . If you’re traveling to South America in summer, you should have Patagonia (at the southern end of South America) high up on your list of things to do. With this list, I show you the best places to visit in Patagonia. The climate down there is pretty rough, especially in the very south - if you plan to do hiking or camping, the best time for a trip is between the end of November and the beginning of March.
1. Bariloche, Argentina
The fact that Bariloche is well connected (airport, direct bus to and from Buenos Aires) makes it the perfect starting point of a round trip through Patagonia. But more than that: the combination of mountains, lakes and green forests results in its beautiful scenery.
2. Futaleufú, Chile
Further down south and a bit harder to access is the small Chilean village Futaleufú which is located at the border to Argentina. The reason which makes it worth it: the Futaleufú River is often referred to as one of the best white water spots for rafting in the world. The landscape along the river is unique and, due to its location, still pretty much untouched.
3. Puerto Rio Tranquilo, Chile
If you want to get there quickly, you should travel through Argentina and cross over to Chile Chico as this place is also very remote. The reason to do so: the marble caves in the General Carrera lake.
4. Torres del Paine, Chile
Personally the national park Torres del Paine is my number 1 attraction in Patagonia - you should take some time and do a multi-day trek to experience as much of it as possible: glaciers, forests, impressive mountain ranges, lagoons and rivers.
1. What is the best time for hiking in Patagonia?A.October 1—November 1 | B.December 25—January 15 |
C.March 5—April 1 | D.November 5—June 7 |
A.It lies in an easily accessible village. | B.It is ignored due to rafting sports. |
C.It is the best rafting river in the world. | D.It still has untouched landscapes. |
A.Bariloche. | B.Futaleufú. |
C.Puerto Rio Tranquilo. | D.Torres del Paine. |

9 . The grass swung gently above a crack in the limestone (石灰岩) and Ludvik Husu realized he had found what he was searching for: a new cave in Slovenia’s dramatic Karst (喀斯特) region.
The cave enthusiast, with more than 50 years of experience, told AFP that “the conditions were perfect ... all the signs pointed to something beneath” as he felt the air current push up from below.
The 63-year-old had come across a new, 60-meter-deep limestone cave, a discovery that made the headlines this summer in a country that prides itself on its 14,000 underground caves.
The tiny Alpine nation is unusually rich in caves, which are a major tourist attraction. Perhaps the best known is the Postojna cave system, the longest in Europe, discovered by another amateur enthusiast two centuries ago. It extends for 24 kilometers and has offered up valuable finds for biologists.
Stanislav Glazar, a Postojna cave guide, told AFP that more than 150 species have been discovered in the system.
Glazar said Postojna is one of the richest caves in the world “in limestone formations.” The cave, located about 50 kilometers south of the capital Ljubljana, was also home to the world’s first cave tourist train, which began transporting visitors in 1872.
Elsewhere in the Karst region, the cave systems are of historical, cultural and even extraterrestrial interest. For instance, the UNESCO-listed Skocjan system was where the European Space Agency sent some astronauts to prepare for life in space.
“Astronauts know that the Karst world is exceptional, in a similar way to the environment in space: you don’t know what to expect at your next step,” said Skocjan Caves director Tomaz Zorman.
But for Husu, it’s the exploration that proves most rewarding. Once he knows there is something beneath, he digs around the crack to widen it and alerts fellow cavers to help gain access. He then uses ropes and a lamp to go down to what are vertical entrances in most caves. But doesn’t he feel scared to enter such unexplored depths?
“You enter a cave out of curiosity — there is no fear! Those who feel fear should stay home,” he said.
1. What was people’s attitude towards Ludvik Husu’s new finding this summer?A.Critical. | B.Positive. | C.Doubtful. | D.Indifferent. |
A.It has little biological value. |
B.It has diverse limestone formations. |
C.It is the most famous cave system in Europe. |
D.It has been open to the public for two centuries. |
A.Financial. | B.Political. | C.Alien. | D.Biological. |
A.Slovenia is known for its Karst landforms. |
B.Ludvik Husu started exploring caves before he was 13. |
C.Slovenia has the most underground caves in the world. |
D.Ludvik Husu is often upset about entering unexplored caves. |
