Are you looking for a place to spend a holiday? Here are two great beaches for you to consider.

Yasawa Island Beach, Fiji

The Yasawa Islands are popular for unspoiled(未经破坏的) beaches and clear blue­green waters. Many mountains stand nearby as well. They offer people a much­needed break from their busy lives. With natural beauty and a lot of sunshine, the islands have become a perfect place to relax. Popular with backpackers, the South Pacific islands also offer many activities such as sailing, visiting local villages and enjoying an evening on the beach with campfires and barbecues. In particular, the Yasawa Island Beach is an affordable relaxing place for tourists.

Eagle Beach, Aruba

Even if you are not one of many American students taking a break from the stresses of college life, you have probably heard people talk about the island—how it offers wild adventures and relaxing activities. No one can say "no" to its Caribbean charm(魅力). In particular, if you have been to Eagle Beach, you will never regret the trip to Aruba. Like an eagle that spreads its wings widely, the beach is known for its long coastline. The Eagle Beach is also known for its soft white sands and clear waters. However, what you can see is not just a wide view of sand and sea. If you're lucky, you can observe sea turtle hatchlings(幼崽) as they make their way to the ocean.

Travelling around the world with children is difficult enough, while attempting it without using motorized transport is even more of challenge. Even so, Dario Schworer, a 42­year­old climatologist and mountain guide, and his 33­year­old wife Sabine are on a journey to do just that.

The Swiss couple want to travel across the world's oceans and climb the highest mountain on every continent to promote Earth­friendly ways of life.

"We are collecting good examples of dealing with climate change and living in harmony with nature and we want to spread such ideas, " Schworer said. "We want to help people affected by global warming and to inspire children for the future. "

Recently after having spent three months teaching children in the Everest region, the couple want to show it is possible to travel through the world's climate zones using just human power and forces of nature.

In the 47 countries they have visited, they have collected 22 tons of trash, taught people in Ecuador how the sun's rays can be used to clean water and inspired a person in Chile to build a house on water with recycled plastic bottles as a foundation. They have also collected trash in the mountains of Nepal with school children.

So far they have communicated with 45, 000 children from South America, Australia and Asia, giving presentations about the importance of recycling and using alternative energy like solar and wind power.

When they began their adventure in 2003 they had no children of their own. But since then two has become five：daughter Sabine is now five years old, Andri was born in Chile and baby Neo was born in Australia.

Initially the couple thought they would complete their travels in four years, but now, they believe it could take seven more.

"Since our belief is the need to respect nature, we travel only when conditions are good, " Schworer said.

Rick Anderson says he isn't scared of sharks and he is appealing to others to learn to love them.

"I try to convince people that looking at a shark eye to eye is totally different to sitting on a surfboard or a boat looking at every shadow that goes underneath thinking it's a shark coming to get them, " he said. "Eye to eye they look at you, you look at them and you go your own way. "

"I find that once people see their first sharks, their whole attitude changes. They realize that they are not as scary as what they thought they were, " Mr Anderson said. He compares sharks to dogs, in the way they show their behavior and attitude towards humans. "You're not going to go up to a dog that is arching(拱起) its back and making a low sound in the throat at you, " he said. "If a shark is arching and its fins(鳍) are down, it's telling you to move on. " He admits he thought the shark was trying to attack him the first few times.

Mr Anderson is against the controversial policy introduced in Western Australia to kill a shark if it presents a threat to humans. He says many of the same things that occur in Western Australia are also happening in New South Wales.

Mr Anderson says that sharks come closer to shore because they are attracted to the smell of whale carcasses(尸体) which have broken down after being buried in the sand on many beaches.

Mr Anderson often sees grey nurse sharks, fur seals, leopard seals, penguins and fishes of a range of colours in the Pacific Ocean along Bellingen Shire. "Depending on the time of the year, you can get a good mixture of sea creatures moving through there, " he said. Tiger sharks are his favourite kind of sharks. He describes them as pigheaded but also graceful creatures.

For years, the giant squid(大王乌贼) had remained a modern mystery. Living in the dark depths of the ocean, the creature is difficult for scientists to observe directly. It had also managed to avoid all attempts to film it. That changed last July: for the first time ever, scientists were able to catch the giant squid on video in its natural habitat. They were amazed by what they saw. The scientists filmed the squid in the North Pacific Ocean, south of Tokyo, Japan. They followed it down to a depth of 2, 952 feet. They shot more than 23 minutes of video before the squid swam off into even darker depths. The video footage will be released to the public later this month on The Discovery Channel.

Tsunemi Kubodera, a zoologist at Japan's National Museum of Nature and Science, led the team that filmed the squid. The team went into the ocean in a small submarine with lights invisible to both humans and squid. Since giant squid eat smaller squid, the scientists released a small squid as bait(诱饵). Then the scientists waited in the pitch black for the giant squid to approach.

The color video shows the creature floating vertically, eating the bait squid. The giant squid is 9 to 10 feet long and is missing its two longest tentacles(触须). With those tentacles, it could have measured up to 26 feet long. It has huge black eyes, the size of dinner plates, "It was shining and so beautiful, " Kubodera said.

Because the deep ocean is so unfriendly to humans, little is known about the giant squid. Scientists say catching the mysterious creature on video is an important step toward understanding it. For centuries, sailors had reported seeing a huge, ocean­dwelling beast, thought to be the giant squid. The creature is also believed to be the subject of the Nordic myth of the kraken, a sea creature that supposedly attacked ships in Scandinavian waters over the past thousands of years.

参考词汇：世界海洋日World Oceans Day

One weekend in July, Jane and her husband, Tom, had driven three hours to camp overnight by a lake in the forest. Unfortunately, on the way an unpleasant subject came up and they started to quarrel. By the time they reached the lake, Jane was so angry that she said to Tom, "I'm going to find a better spot for us to camp" and walked away.

With no path to follow, Jane just walked on for quite a long time. After she had climbed to a high place, she turned around, hoping to see the lake. To her surprise, she saw nothing but forest and, far beyond, a snow­capped mountain top. She suddenly realized that she was lost.

"Tom!" she cried. "Help!"

No reply. If only she had not left her mobile phone in that bag with Tom！Jane kept moving, but the farther she walked, the more confused she became. As night was beginning to fall, Jane was so tired that she had to stop for the night. Lying awake in the dark, Jane wanted very much to be with Tom and her family. She wanted to hold him and tell him how much she loved him.

Jane rose at the break of day, hungry and thirsty. She could hear water trickling(滴落) somewhere at a distance. Quickly she followed the sound to a stream. To her great joy, she also saw some berry bushes. She drank, and ate a few berries. Never in her life had she tasted anything better. Feeling stronger now, Jane began to walk along the stream and hope it would lead her to the lake.

As she picked her way carefully along the stream, Jane heard a helicopter. Is that for me? Unfortunately, the trees made it impossible for people to see her from above. A few minutes later, another helicopter flew overhead. Jane took off her yellow blouse, thinking that she should go to an open area and flag them if they came back again.

But no more helicopters came and it was getting dark again.

……

It was daybreak when Jane woke up.
