Several days ago, my classmates and I visited to the Cincinnati School for the Blind and Deaf. We had party with some of the student there and had a wonderful time. I met a girl at the party. She couldn’t speak or hear, but we “talked” by writing on each other hands. When saying goodbye, she writes on my hand, “Please come here as often as possible.” Many people are concerning about disabled people and give her money. However, I think which we should do is to communicate with them rather than give money. If you want to help disabled people, making friends with them and visit them regularly. Nothing is much important than friendship.

Anyone who wants to learn something can enroll (注册) into a good school offering online courses and complete their education. Besides being convenient, there is no age limit; one can take a course anytime and at any point in their career.

Online learning also means that people have more time for their own life while continuing their education. They are able to learn when it’s convenient for them, and in many cases the courses can be completed in less time than at a traditional school. People can go to work during the day and finish their homework at night. Parents can spend time with their children and then complete online classes when their children are at school or asleep. Since people don’t have to take part in any classroom activities, it does not do any harm to their lives. They can work and learn at any time of the day and at their own speed.

Many people find that online courses are less expensive than traditional ones. Classroom teaching is usually expensive and not suitable for a lot of people. Through online learning, one can save a lot. People don’t have to spend more money on traveling, staying in hotels or eating in restaurants. Online courses are a good choice for those who are short of money but want to learn something and improve themselves. According to the U.S. Department of Education, students learning online have not only saved a lot of money but also performed better than those learning in traditional schools.

Of course, online learning requires a regimented lifestyle and the ability to learn on one’s own. For people who are not strict with themselves, online learning can be a real challenge. For busy people who take online classes, time management can be a challenge. They have to decide for themselves when to work on class tasks and how long they will need in order to finish the work. So, people must think about all of these things before making a choice.

9 . Thanks to its harsh environment, Antarctica remained largely untouched by humans for many millennia, allowing a thriving (旺盛的) ecosystem to evolve. However, since the 1990s, the last true wilderness on the planet is becoming an increasingly popular destination for adventure-seeking tourists. Now, a new study declares that the visitors may be leaving behind harmful bacteria which could devastate the area’s native bird population.

Humans can infect animals with illnesses such as the flu. Researchers, however, believed that the Antarctic animals were immune to the danger due to the continent’s extreme weather. However, microbiologist Marta Cerda-Cuellar was not convinced.

She and some colleagues decided to examine waste samples from Antarctic birds for evidence of human bacteria. To ensure the waste was not polluted, the scientists had to collect it from the birds themselves.

The results of their study revealed the presence of several types of human bacteria in the bird waste. This included a common strain (品种) of bacteria that causes food poisoning in humans. The researchers say the bacteria strains were resistant to commonly-used human antibiotics (抗生素)，indicating they were brought in by the visitors, rather than migratory birds (候鸟).

“These strains, which are a common cause for infections in humans and livestock, do not usually cause death outbreaks in wild animals,” says Gonzalez-Solis. “However, the emerging or invasive pathogens (病原体) that arrive to highly sensitive populations could have severe consequences and cause the local collapse and extinction of some populations. “The researcher also fears the presence of these bugs could foreshadow the arrival of other, more deadly, pathogens as the number of tourists people increases.

Experts believe the only way to prevent the mass destruction of the birds is to impose stricter regulations or, at least, put the ones already in place into effect. For example, while the Antarctica Treaty requires visitors to carry their waste back home to safeguard the pristine environment, the regulation is rarely enforced. Nowadays, some officials are taking steps to save the vulnerable birds before it’s too late.

10 . Film director James Cameron first became interested in sea exploration when he was a little boy. His love for the ocean grew after he made the 1989 undersea adventure film The Abyss and the 1997 blockbuster Titanic, one of the most successful movies of all time. Following that big success, James Cameron decided to put his film career on hold to become a sea explorer.

In 2012, James Cameron made a journey to the deepest spot in the Mariana Trench, known as Challenger Deep. And now the great journey has been made into a documentary film, named James Cameron’s Deep-sea Challenger 3D.

In James Cameron’s fantasy films, such as Avatar and The Abyss, the unexplored areas are decorated in colors and full of danger. But on his dive into Challenger Deep, the reality proved far different: white, deserted and dull.

“I felt like I had gone to another planet,” Cameron said after returning from the cold and dark place in the Western Pacific Ocean, nearly 7 miles below the surface.” I really have a sense of being separated and realize how tiny I am down in this big, black and unexplored place. “Cameron captured the moonlike landscape of the deep sea and documented the sea creatures he observed in the ocean.

James Cameron’s Deep-sea Challenger 3D tells the story of Cameron’s journey. It is a film about determination, danger and the ocean’s greatest depths. The movie shows a unique insight into Cameron’s world when he makes his dream reality and makes history by becoming the first person to travel alone to the deepest point on the planet.

It’s an exciting film and inspiring reminder that our beautiful planet still has a lot to explore.
