Queensland is one of the most amazing states in Australia. It has some of the most beautiful natural scenery on the planet, with the Great Barrier Reef, rainforests and impressive beaches.

The Great Barrier Reef

It is one of the world's largest natural features. It stretches more that 2,300 km along the north eastern coast of Australia from the northern tip of Queensland to just north of Bundaberg. The things that most surprise visitors to the reef are the colors.

Without doubt, the best way to see the Great Barrier Reef is by diving. If you have a little extra money and you are feeling a bit lazy, you can fly over the reef in a plane.

Fraser Island

Another area of natural beauty is Fraser Island. This is the world's largest sand island. It's best visited from Hervey Bay on the mainland, where there are a number of places offering trips around the island. To fully appreciate Fraser Island you should go for three or four days. Attractions include some beautiful fresh-water lakes, particularly Lake Wabby and Lake Mckenzie. You can walk around these on white sands untouched by human footprints. Indian Head also has some beautiful views. Braver travelers can go and watch sharks circling the water hundreds of meters below.

The Whitsunday Islands

    It would be a pity to travel around Queensland without taking a trip around the Whitsunday Islands. They were named by Captain Cook in 1770, after the day on which he arrived. Here are some of the great things you can do there.

●Cruise around them on a relaxing trip.

●Take a sailing course.

●Look at the aboriginal (土著的) paintings in caves on Hook Island.

●Have fun in the water doing lots of water sports.

    So, will you be going to Queensland?

    Chinese students always complain that they're under great pressure and don't get enough sleep. But they may be surprised to learn that they're much luckier than their peers (同龄人) in South Korea and Japan, according to a recently published report, conducted by Shanghai Academy of Social Sciences on the physical and mental health of senior high school students in the three Asian countries.

    According to the study among nearly 6,000 high school students in the three countries, Chinese students are the tallest but poorest in physical fitness. Chinese students are on average 168.17cm, compared with 167.61cm for South Korean students and 164.70cm for Japanese students. Chinese students asked for sick leave more than students in other countries. About 72 percent of Korean students never asked for sick and injury leave during high school, compared to 53 percent for Japanese students and 45 percent for Chinese students. Moreover, Chinese students drink alcohol and smoke earlier than Korean and Japanese students. Around 70 percent of Chinese students have drunk alcohol, compared to 50 percent for Korean and Japanese students.

    According to the survey, Japanese and South Korean students suffer more pressure than their Chinese peers. Statistics (统计) show 16 percent of students in China said they experienced mental pressure often over the past year, while the numbers in Japan and South Korea were 33 percent and 47 percent respectively. Their worries come from “study”, “future after graduation”, “friendships” and “relationship with their parents”. To go with stress, 57.9 percent of Korean students sleep the least, less than six hours a day, compared with 46.6 percent of Japanese students and 30 percent of Chinese students.

    More Chinese students were satisfied with their physical appearance, double that of students in the survey from Japan and South Korea. The report said that over half of students in South Korea had tried to lose weight in the past year, while in China the figure was only 22 percent.

    In measures of self-worth, such as “I think I am valuable” and “I think I am successful”, “I can complete many things”, “I won't give up to failure,” Chinese students showed greater self-confidence than students in Japan and South Korea.

    Move over millennials(千禧一代), here comes Generation Z, today's youngest group.

    Born in 1995 or later, a lot of Gen Z-ers are entering into adulthood and will soon join the workforce. People of Generation Z have grown up with the internet. Policy makers, sociologists, as well as employers and marketers, are trying their best to understand these young people. So, how should we pin down the Gen Z-ers?

    Most people will agree that the single biggest difference between Gen Z and other generations is how connected they are. This is a group of people who were hooked up to social media as soon as they were born. A recent Guardian article says that the average teenager in the UK has at least 150 followers on Instagram and spends around half an hour a day on Snapchat, an image messaging app. “We are the first true digital natives,” Hannah Payne, an 18-year-old UCLA student and lifestyle blogger. “I can almost create a document, edit it, post a photo on Instagram and talk on the phone at the same time, all from the user-friendly interface(界面) of my iPhone.

    The Guardian also notes that young people in the UK are becoming more active in politics. Voting is just one way of making one's voice heard. Most of Generation Z are still too young to vote, says the Guardian. Instead of party politics, they focus more on single-topic issues such as feminism(男女平等)or climate change. And “much of the civil engagement and organizing they do takes place on social media rather than through traditional political structures,” according to the newspaper.

    Did you ever notice your shadow at different times of the day? Shadows change as the day goes on.

    In the morning the sun makes long shadows. In the middle of the day, the sun seems to be right over your head and your shadow is very, very small. As the sun goes down in the afternoon, shadows grow very long again. But the long afternoon shadows fall in a different direction from the long morning shadows.

    Long, long ago people told time by the shadows. Put a piece of paper in the sunlight. Stand a pencil in a spool in the middle of the paper. The shadow of the pencil will fall on the paper and move as the day goes on. Use a watch and every hour marks the place where the shadow falls. Now your paper is a sundial（通过太阳辨别时间的日规）and you can tell every sunny day. Just look at your paper sundial and see where the shadow falls.

    When slaves were first brought over from West Africa to the southern parts of America, they brought along with them aspects of their own culture—religion, dance,language, music, and cuisine.A mix of the two cultures eventually appeared.The religious dance of the ring shout turned into modern dances like the Charleston, and tribal chants slowly transformed into sorrowful hymns (圣歌) sung by slaves that described their hardships.

    These soulful accounts by slaves of the severe climate and conditions began to be called “the blues”,which continued in popularity among African Americans after the Civil War.This music increased in popularity into the early 1900s when many black musicians became an important part of the music industry.

    The slaves that had been brought over were from all different regions of West Africa, but they worked together until they gradually formed a common culture.This strengthened the identity of their music that, in the 1950s, eventually led to the beginning of rock and roll.The Beatles, the most influential band of the 1960s, are often determined as the accelerator that resulted in the ideology (意识形态) surrounding music that is still around today.The freedom and individuality associated with that time period brought forth a whole culture surrounding music.It was not just music any more, but a lifestyle.

    Over the decades, music has developed into such a vital part of society and pop culture.Musicians are glorified, with tons of adoring and screaming fans.The modern technology of present day has allowed for a greater gap between the creator of the music and the fans, as well as a widespread commercialization of music.However, criticisms of modern pop music often arise due to its mass production, and now there is a lack of the same soul and quality of naturalness and simplicity in music that was rising in the early 20th century.

    NOT all memories are sweet. Some people spend all their lives trying to forget bad experiences. Violence and traffic accidents can leave people with terrible physical and emotional scars. Often they relive these experiences in nightmares.

    Now American researchers think they are close to developing a pill, which will help people forget bad memories. The pill is designed to be taken immediately after a frightening experience. They hope it might reduce ,or possibly erase(抹去),the effect of painful memories.

    In November, experts tested a drug on people in the US and France. The drug stops the body releasing chemicals that fix memories in the brain. So far the research has suggested that only the emotional effects of memories may be reduced, not that the memories are erased.

    The research has caused a great deal of argument. Some think it is a bad idea, while others support it.

    Supporters say it could lead to pills that prevent or treat soldiers' troubling memories after war. They say that there are many people who suffer from terrible memories.

    "Some memories can ruin people's lives. They come back to you when you don't want to have them in a daydream or nightmare. They usually come with very painful emotions," said Roger Pitman, a professor of psychiatry at Harvard Medical School. "This could relieve a lot of that suffering."

    But those who are against the research say that changing memories is very dangerous because memories give us our identity (特质). They also help us all avoid the mistakes of the past.

    "All of us can think of bad events in our lives that were horrible at the time but make us who we are. I'm not sure we want to wipe those memories out, "said Rebecca Dresser, a medical ethicist.
