1 . Friendship is an important part of human life. Friends can share our joys and sadnesses. We aren't alone. Many different animals also make friends.
Recently, a British research team finished an eight-year study of Indo-Pacific dolphins off the coast of Western Australia. These dolphins can use different tools to search for food. The researchers found that these dolphins are more willing to hang out with partners that like the same tool. Other factors, like family closeness or sex, have no impact on this relationship. It suggests that dolphins form social bonds based on shared interests.
Apart from dolphins, elephants and horses are also known to form friendships. Are friendships only limited to the same species?
Of course not, The Atlantic reported. In 2015,Timur, a goat, was left in the enclosure（围场） of a tiger, Amur, as a meal. But instead of eating Timur, Amur liked to play with him and got angry when others were close to his friend. That's because in captivity(圈养）, animals don't need to spend much time and energy marking their land or looking for mates the way they would in the wild. They are actually more likely to feel bored.
More interestingly, animals not only make friends but also try to keep lasting friendships. Take bats for example. In 2011, scientists found bats often hang out with a few particular friends, keeping loose ties to the rest of their group. Humans are different. "We do not work, play and live together with the same friends all the time," Swiss zoologist Gerald Kerth explained. "But nevertheless, we are able to maintain long-term despite our often highly dynamic（充满活力的）social lives."

3 . The great avenues are quiet, and the shops are closed. There’s the smell of fresh bread from a bakery somewhere. It would be hard to say which time of the day in Paris I prefer but this is probably it. Soon the streets will be full of people and traffic. As with most other cities, you see the real Paris when the city wakes up.
There is, however, another part of Paris which is silent and free from people 24 hours a day. Under the city are hundreds of kilometers of abandoned tunnels. During the 19th century, Paris needed more stones for buildings above the ground, so people dug tunnels beneath the city. After that, many farmers grew mushrooms in them. During World War II, the French soldiers also used them. Since the 1970s, many young people have started spending days and nights below the city in these tunnels. It’s now a place for parties, theatre performances, art galleries – anything goes!A “normal” tourist can visit some parts of Paris’s tunnel system, such as the underground cemetery, where you can see the bones of about six million Parisians. The bodies came from cemeteries above the ground two centuries ago when the city needed more space.
However, people are not allowed to enter other parts of the tunnel system. It’s very dangerous because some tunnels might collapse and people will be trapped below. Nevertheless, there are people who will take you to visit them. I have found two “unofficial” tour guides who take me through many tunnels. After a couple of hours we arrive at a room which isn’t on any map. The room is comfortable and clean with a table and chairs and a bed. The guide tells me there are many other places like this. “Many people come down here to party, some people to paint.... We do what we want here.”

4 . Great Activities for Nature Lovers
Hiking
One of the easiest and most accessible ways to get close to nature is by setting out on a good old fashioned hike. Hiking generally doesn't require any fancy equipment or special skills, just a piece of map and a thirst for adventure. This activity can be as relaxing as you make it.
Backcountry Camping
Why limit yourself to just a day hike when you can have a full weekend for a longer adventure? Backcountry camping involves packing your tent，sleeping gear ,food, and water on your back to set up camp in a remote location. I you’re an experienced hiker and camper ,this is an excellent way to test your survival skills and explore the wilderness.
Mountain and Road Biking
Unlike long hikes through the woods , biking allows you to cover more ground and travel farther in nature. Mountain biking typically involves riding up and down steep slopes , between trees , and over rocks. If this sounds too intense or your tires aren't suited for rugged terrain( 地形) , consider taking a road bike on paved trails through forest preserves or along country roads.
Gardening
Contrary to popular belief, you don't have to travel beyond your own backyard to experience the beauty of nature every day. If your personality is less adventurous or your mobility restricted, consider planting a garden to grow your own vegetables , fruit , herbs，or flowers. There's something truly satisfying about mixing up a salad with fresh ingredients you grow yourself. One of the best parts about spending time in gardening is that it doesn't have to break your budget and anyone can do it.

5 . Have you ever been into a cave? If not, please follow us and explore some of the most beautiful caves from around the world!
Marble Caves
Located in the center of Lake General Carrera, the Marble Caves in Chico, Chile, are only accessible by boat. The surrounding crystal clear waters allow visitors to see the rock formations beneath them while the rock ceilings above change color(depending on the writer levels and the season). The best time to visit: during sunrise and sunset, when the sun’s rays light up the cave walls, making it an experience to remember.
Reed Flute Cave
Reed F1ute Cave known as “the Palace of Natural Arts” is located in the northwest of Guilin in southern China.The limestone cave offers a grand fairyland of stalactites(钟乳石), stone pillars, stone curtains, birds, plants and animals in fantastic shapes and colors.
Fingal’s Cave
This incredible sea cave is located on the uninhabited island of Staffa in Scotland. The cave’s size, shape, and naturally—arched(拱形的) roof combine with the waves to create strange sounds that enhance its cathedral—like atmosphere.
The Blue Grotto
The Blue Grotto is the symbol of Capri. It is a sea cave found on the coast of the island and is a well-known spot to all who visit the area. This cave is unique for its brilliant blue light which comes from two sources: the entrance to the cave and a bigger hole beneath the entrance. When viewed from inside the cave, the entrance appears as a brilliant white light just above the waterline, while the underwater hole, which is the larger source of light, provides a blue light.

6 . Most animals on land are known to us, but many living things underwater are not. Now let’s get to know some of them.
Sea cucumber
Sea cucumber are strange animals living at the bottom of the sea. They wear brown or white green coats . When summer comes, they stay deep to sleep because they are afraid of heat. And when it is autumn, they move to shallow (浅的) water and get their food.
Pike
The pike is a kind of freshwater fish. They are good swimmers and like swimming near boats, waiting to be fed. They have sharp teeth to catch fishes. When they are young, they live in groups. However, when they grow up, they prefer to live alone.
Cuttlefish
A cuttlefish can swim quite fast, so it is also called rocket (火箭) fish. It has eight arms and two feelers on its head, just around its mouth. It ejects ink (喷墨) when it is in danger. Its meat is delicious, and it is often the first choice for many people.
Octopus
An octopus has long arms, with which to catch food and protect itself. When it is sleeping, one or two of its arms are still on duty, keeping moving. Once it feels something dangerous, it can wake up at once to take action.
