【推荐3】International Tiger Day is an annual celebration to raise the awareness of tiger conservation. It’s held on 29 July. Governments and citizens across the world organize awareness programs on that day to spread the importance of protecting tigers.

From ancient times, tigers were the subject of constant attraction for their beauty, size and sometimes mythical stories related to them. People’s fascination (迷恋) for tigers is obvious from the fact that tigers are still a part of many national symbols and flags. Tigers are the largest cat species. Unfortunately, the population of tigers is fast decreasing. Every part of tigers from tail to skin to nail is traded in the illegal market for very high values. Many tigers are hunted, which is one of the key threats to their existence. They are also caught and raised as pets. 97 percent of the world tiger populations decreased in the last 100 years and only 3,890 tigers are left. If tigers get extinct, we will lose a species. And it also means that enough forests have been destroyed, which may endanger many other species.

For us, tigers are symbols of wildlife’s fighting for survival. It reminds us of the dangers we face because of people’s over-exploitation (过度开发) of the nature. It’s an opportunity as well. Many efforts are on the way to double the tiger population by 2024. Strict national and international laws are against hunting and trading tigers. As a result, the number of tigers in the wild has risen for the first time in more than 100 years. Even though this is just a small increase, it’s a huge symbolic victory in our efforts against the destruction of forests and wildlife. It’s very important that we all join together in this effort, not only to save tigers, but also to save our forests.

You can also use other senses when you choose your food. You may like it because it smells good or because it tastes good. You may dislike some types of food because they do not look, smell or taste very nice. Different animals use different senses to find and choose their food. A few animals depend on only one of their senses, while most animals use more than one sense.

Although there are many different types of food, some animals spend their lives eating only one type. The giant panda eats only one particular type of bamboo. Other animals eat only one type of food even when given the choice. A kind of white butterfly will stay on the leaves of a cabbage, even though there are plenty of other vegetables in the garden. However, most animals have a more varied diet. The bear eats fruits and fish. The fox eats small animals, birds and fruits. The diet of these animals will be different depending on the season.

Humans have a very varied diet. We often eat food because we like it and not because it is good for us. In countries such as France and Britain, people eat foods with too much sugar. This makes them overweight, which is bad for their health. Eating too much red meat and animal products, such as butter, can also be bad for the health. Choosing the right food,therefore, has become an area of study in modern life.

That year, Neelim Kumar Khaire made a Guinness world record for staying 72 hours in a glass box with 72 poisonous snakes ： 27 monocellate cobras, 24 russell's vipers, 9 binocellate cobras, 8 banded kraits , and 4 common snakes.

Kaire's love for snakes began while he was working at a five-star hotel near Bombay. " Snakes were frequent visitors at my place in Matheran," Khaire said. "I hated killing such beautiful creatures, most of which were harmless. So I started catching and releasing（释放）them in the Sahyadri hills. I once caught a snake and took it to the Haffkin Institute in Bombay. I was told that it was poisonous and too risky to be carried in this way. The happening increased my courage and so began my fascination with snakes.”

Khaire said he first thought of setting up a world record when he came across some reports of Peter Snyemaris staying with 18 poisonous and 6 semi-poisonous snakes in Johannesburg, South Africa, for 50 hours.

“I thought an Indian responsible to create a world record in this field as India is known abroad as a country of snakes,"   said Khaire.

So, for three days, Khaire lived in a small glass box filled with poisonous snakes at B. J. Medical College in Pune, India. While resting in a chair, he often had to deal with snakes that climbed onto him. But after72 hours, Khaire left the box without a single bite.

Using the initial（最初的）funds from his great event, Khaire created The Katraj Snake Park that was later known as The Rajiv Gandhi Zoological Park. This unique park helps nest nearly 160 species of snakes and other wild animals.

【推荐1】A person seeking a new career opportunity might consider looking in a museum. Museums provide jobs in fields such as research, management, graphic arts, public relations, education, preserving, cataloging, fund-raising, and construction. A museum may have one employee or thousands.

Many museum workers do not work directly with the objects in the museum; for example, the staff of a finance department prepares budgets and financial reports. Accountant and bookkeeper are typical positions. Staffers in the development department, meanwhile, work to increase museum membership and donations and to plan fund-raisers, such as dances or auctions. Publications department personnel may write newsletters, brochures, or books.

Some museums have an education department responsible for planning talks, teaching workshops, directing tours, or training tour guides.

People who prefer to work directly with a museum's collection have many career options. A person who pays attention to detail may enjoy being a registrar, the person who keeps track of the objects in a museum. Registrars keep records of objects, noting what they are, when and how they were obtained, and whether they are on loan to another museum or on display.

Curators are the people responsible for a museum's collection. One of their duties is to choose items for exhibits; then they work closely with designers who plan the best way to arrange exhibits. Other specialists do things such as arrange lighting or build display cases. Expert craftspeople can also find jobs re-creating historic buildings, such as the Pilgrim village at Plimoth Plantation.

A museum also often employs conservators to repair and take care of its collection. Many conservators are specialists who care for one kind of item, such as books or paintings. The Henry Ford Museum employs many conservators, including some who are experts in caring for antique cars.

Some historic homes, such as George Washington's home in Mount Vernon, have gardens, farms, and woods, as well as buildings. Gardeners are employed to care for the grounds and livestock handlers to care for farm animals.

Museums offer many other career opportunities too. They may have gift shops where sales assistants sell books, postcards, and other items or. restaurants where meals are prepared and served. Depending on one's interests, a museum could be a great place to look for a job.

The news spread quickly, as many people shared the article on Facebook and other social media sites. But pet owners had nothing to worry about—the article was made­up.

Many fake (虚假的) news are harmless, but others might have played a role in real­world events. When it comes to online news, even adults can have a hard time telling fact from fiction. Education experts say kids should start learning how to tell the difference.

Of course, there are plenty of reputable websites you can visit to read the news. Well­known news organizations, such as The New York Times and the Associated Press, have their own sites.

But many other online “news” sources aren't always reliable. And many students have trouble finding out when articles aren't entirely true or are trying to persuade them to think in a certain way.

Why would someone purposely publish an article that isn't true? The most common reason is to make money. Websites are paid by the companies that post ads on them. Companies want to place their ads on sites that get a lot of visitors. So people create fake news with attention­catching headlines to try to get users to click on them.

Some of the biggest websites are trying to stop the flow of fake news. Last November, Facebook and Google banned fake news sites from advertising on their pages. Facebook is also working with fact­checking organizations to identify and flag fake articles. But experts say the best way to slow the spread of fake news is for people to be more skeptical of what they read online.
