Are you dreaming of taking a trip on your own? Here is some advice on how to make your once-in-a-lifetime journey and how to stay safe when you get there.

    Before you begin to look at places, activities and plane tickets, you must set a budget. When you search through the websites about travelling, it can be so easy to add another week here or there, or choose an extra activity. Setting a budget can avoid（避免） creating a huge bill, which starts very small.

    With so many countries on this planet, it is difficult to decide where to go. By narrowing down your search to voluntary (自愿的) work or a relaxing holiday, you can save a lot of time looking through websites.

    After deciding where to go, you need to research the country. Find out when each season is. It would be disappointing if you were taking part in an outdoor-based activity and it rained most days. Look into medical information, as you may need certain medicine for certain countries. Above all, make sure you can afford to go to this country and take part in the activities you have dreamt about. Don't raise your hopes too high before you know for certain it is within your budget.

    By carrying a credit (信用) card with you at all times,  it is possible to stop yourself getting lost. Mobile phones are very important as well. However, do not depend completely on them, since electronic machines can break without warning. Therefore, always carry a list of emergency (紧急情况) phone numbers, names and addresses. Finally, learn a little of the language. Do not expect that the people there speak your own language. After all, you are in their country.

    What do you usually do to comfort your friends when they are sad? You probably pat them on the shoulder, or give them a warm hug.

    We used to think that knowing when and how to comfort others was an ability that only humans have. But scientists have discovered that apes (猩猩) have this ability too.

    Two researchers from Emory University in Atlanta, US, went to an Ape Protection Centre in Congo to study bonobos (倭黑猩猩), which are closely related to humans.

    The researchers analyzed the bonobos' reactions (反应) after more than 370 cases of stressful situations, such as fights and losing temper, and found that some bonobos rushed to hug those that were screaming after being attacked, just like humans would have done.

    However, researchers found that not all bonobos were able to comfort others. In the protection center, many bonobos are orphans whose mothers were killed by hunters. They were found to be more worried in times of tension and have greater difficulty controlling their own emotions, making them worse at reaching out to help friends in need.

    "Orphans, who have not had the benefit of a mother helping them handling their emotions, are much worse at comforting others," Professor Frans de Waal told TheTelegraph. "Bonobos with moms were able to curb their negative emotional reactions more quickly. Therefore, they pay more attention to others."

    This pattern mirrors the way that human children have been found to react. Those who are good at handling their own emotions—for example, those who can calm themselves down more quickly after upsetting experiences—are usually better at expressing their concerns for others.

    Binge-watching is when a person watches more than one episode of a show in quick succession（一连串,连续）". With developments in the speed and connectivity of the internet, increases in technology and the rise of on-demand entertainment companies, people can now have their favorite shows streamed directly to their television at their convenience.

    This behavior is nothing new. In fact, " binge-watching" has been officially listed in dictionaries since 2015. The entertainment companies recognize this behavior and many take steps to encourage it. Often, instead of releasing each episode on a week-by-week basis, an entire series will become available concurrently. Once the episode finishes many platforms will display pop-ups with "you might like suggestions, or will automatically play the next episode".

    However, recent research suggests that out of the more than half of British adults who watch more than one episode of a show back-to-back, almost a third have admitted missing sleep or becoming tired as a result; and one quarter have neglected their household chores. Next we'll be missing work!

    Bingeing has other connections-binge eating, binge drinking and binge smoking. All of them are often associated with a lack of control and a possible route to addiction. Lindsey Fussell, consumer group director, said： "The days of waiting a week for the next episode are largely gone, with people finding it hard to resist watching multiple episodes around the house or on the move." If people find binge-watching hard to resist, coupled with the fact that it has shown to lead to negligence in many, are we witnessing the birth of a new type of addiction？

    The countless of information and entertainment that television and online media can bring us is, many would say, a good thing. However, when the activity begins to bleed into other areas, causing us to stop functioning then it becomes a problem. So, what's the answer？ Moderation! Neither a tiny amount, nor too much. After all, as the old proverb says, "A little of what you fancy does you good."

    Elephants might be the most well-known and well-loved animal in African wildlife. But conservation (保护) of the African elephant faces special difficulties. While the elephant population is half of what it was 40 years ago, some areas of Africa have more elephants than populated areas can support. That's why AWF scientists are studying elephant behavior, protecting habitats and finding ways for humans to live peacefully with elephants in Africa.

    Years ago, overhunting and the ivory trade were the biggest threats to elephants' survival. Luckily, ivory bans (禁令), hunting rules and protected areas protect elephants from these dangers today.

    The 21st century brings a different challenge to elephant conservation — land-use. Elephants walk across borders and outside parks and other protected areas. So they often destroy crops, causing conflicts (冲突) between local farmers and these big animals.

    Successful conservation strategies (策略) must allow elephants to walk freely in their natural habitats while reducing conflicts between elephants and local people.

    AWF researchers are searching for a way to give both elephants and people the space they need. The AWF is collecting information on elephant habitats and behavior. The information they gather will help to develop the widest possible space for elephants.

    The AWF is helping elephants by protecting their habitats. And they also work with local famers to improve their life in order to encourage them to protect rather than destroy elephants.

    New England is the six northeastern states of the United States: Maine, New Hampshire, Vermont, Massachusetts, Rhode Island, and Connecticut. The six states were among the first colonies (殖民地) in America. The colonies were ruled by England, and this is how the area became known as New England. After the Revolutionary (革命的) War the colonies became states.

    Many things are similar in the six New England states. For example, there are many stone walls, fishing villages and forests in these states. The houses and buildings are similar, too. People cut down trees from the forests to make space for their farms and villages.

    They then used wood from the trees and stones from the field to build houses, schools, and churches. Even today, most of the houses in New England are made of wood.

    There are big cities in New England, but there are also small cities and farms, especially in the northern part. There is much industry and business and New England is one of the most populous (人口稠密的) parts of the United States. It has many busy seaports on its long coast. There are always many tourists who enjoy the beautiful lakes, beaches, and mountains and who visit the historical places.
