【推荐1】China Youth says that more and more girl students have entered colleges to study in the recent few years. As we know, once the number of boys was larger than that of girls and boys did much better than girls in our country for a long time. Now, things have changed a lot.

In recent years, the proportion (比例) of girl students is growing fast. In 1998, about 39.7% of college students were girls. In 2000, it was 41.07% and in 2001, the number was 42.14%.

There are several reasons for this.

Firstly, there is little difference between boys and girls in their intelligence (智力). That’s to say, girls are as clever as boys. And boys have more interests than girls, so they may not always do well in their study.

Secondly, girls are more careful than boys. They work harder at school and they do better in all exams.

Another reason is that with the development of society, people pay more and more attention to girls’ education.

【推荐2】In recent years many countries have been faced with the problem of how to make their workers more productive. Some experts claim the answer is to make jobs more varied. But do more varied jobs lead to greater productivity? There is evidence to suggest that while variety certainly makes the worker's life more enjoyable, it doesn't actually make him work harder. As far as increasing productivity is concerned, then, variety is not an important factor.

Other experts feel that giving the worker freedom to do his job in his own way is important.   The problem is that this kind of freedom cannot easily be given in the modern factory with its complicated(复杂的) machinery. Thus while freedom of choice may be important, there is usually very little that can be done to create it.

Another important consideration is how much each worker contributes to the product he is making.   In most factories the worker sees only one small part of the product. Some car factories are now experimenting with having many small production lines so that each worker contributes more to the production of the cars on his line. It would seem that not only is degree of worker contribution an important factor, but it is also one we can do something about.

To what degree does more money lead to great productivity? The workers themselves certainly think this is important. But perhaps they want more money only because the work they do is so boring. Money just lets them enjoy their spare time more. A similar argument may explain demands for shorter working hours.   Perhaps if we succeed in making their jobs more interesting, they will neither want more money, nor will shorter working hours be so important to them.

【推荐3】In the past, man did not have to think about the protection of his environment. There were few people on the earth, and natural resources seemed to be unlimited. Today things are different. The world has become too crowded. We are using up our natural resources too quickly, and at the same time we are polluting our environment with dangerous chemicals. If we continue to do this, human life on the earth will not survive.

Everyone realizes today that if too many fish are taken from the sea, there will soon be none left. Yet, with modern fishing methods, more and more fish are caught. We know that if too many trees are cut down, forests will disappear and nothing will grow on the land. Yet, we continue to cut down more and more trees. We realize that if rivers are polluted with waste from factories, we will die. However, in most countries waste is still put into the rivers or the seas and there are few laws to stop this. We know, too, that if the population of the countries is rising at the present rate, in a few years, there will not be enough food. What can we do to solve these problems?

If we eat more vegetables and less meat, there will be more food for everyone. Land that is used to grow crops can feed five times more people than land where animals are kept.

Finally, if we educate people to think about the problems, we shall have a better and cleaner planet in the future.

【推荐1】Inventions That Will Make Your 2019 a Lot More Interesting

Each year there are countless new products and inventions on the market. Here are some of the most exciting products to come out over the year.

Xbox Adaptive Controller

The Xbox Adaptive Controller is here to make the gaming world more accessible. Microsoft developed the Xbox Adaptive Controller to help those with limited hand and arm mobility (移动的能力) play games. It connects device (设备) such as switches, buttons and joysticks (操纵杆) to create a unique custom controller experience. The product itself was inspired by previous efforts made by groups like the Cerebral Palsy Foundation.

Gravity Blanket

Gravity is in here to help you deal with your anxiety. Starting off as a Kickstarter campaign, the company Gravity has created a therapeutic (治疗的) weighted blanket engineered to be around 10% of your body weight. The super comfortable blanket helps those who have a sleeping problem, and those who may be stressed, or deal with anxiety.

Solar Charged Jacket

If you are a night runner, this one is for you. Created by U.K.-based sporting goods company Vollebak, the Solar Charged Jacket absorbs light during the day and gives off its “green energy” for those who need to be safe after dark.

LynQ

Getting separated from friends or family members at an event or a festival can be annoying. LynQ helps you find your loved ones when you get separated from the group. Unlike smartphones, this compass- like device does not need any Wi-Fi to stay connected. It is a great tool for family vacations.

【推荐2】The royal family is filled with rules, and one in particular might explain why Princess Charlotte is a princess, but her kids likely won't be.

When it comes to the British royal family, one thing is almost always true: they have a pretty confusing set of official rules and protocols. For instance, the royal family doesn't have a last name. And don't forget the fact that Queen Elizabeth celebrates two birthdays every year.

If your head isn't swimming yet, consider the tradition of royal titles. As a British custom, only the daughter of a prince or a prince's wife may be considered a formal "princess". The latter applies to Kate, who is both a princess and the Duchess of Cambridge thanks to her marriage to Prince William, the Duke of Cambridge. And their children, Prince George and Princess Charlotte, also bear official royal titles because their father is Prince William.

However, while Prince George's future children will also carry their father's royal status, any children that Princess Charlotte has will not automatically be considered princes or princesses. Why? Royal custom dictates that royal titles are passed down via sons, but not daughters.

"Royal titles are inherited through sons, so if Princess Charlotte has children they would not automatically inherit the titles (his or her royal highness) HRH, Prince, or Princess," Lucy Hume, associate director of etiquette experts Debrett's, told Town& Country.

Of course, exceptions can (and will!) be made. (Learn about every time the British royal family broke their own protocol.) The Queen has offered HRH status to other royal offspring in the past, including the children of Queen Elizabeth's daughter, Anne. Although Princess Anne and her husband, Captain Phillips, declined, perhaps Princess Charlotte will be extended the same offer when her own children are born.

【推荐3】Whether you’re traveling over your children’s spring break, summer vacation or winter holidays, you’ll find Miami is such a hot spot for families year-round. There are various activities for vacationing kids in Miami, and they can spend one day learning about some of Miami’s rich cultural heritage (遗产),as well as a bit of science and history.

Start your day at Bayside Marketplace. There are plenty of shops and souvenir stands here for all members of the family. Kids will particularly enjoy Art By God, a shop devoted to natural stone, especially fossils(化石).

From Bayside Marketplace walk two blocks north to visit what is perhaps Miami’s most famous historical landmark, Freedom Tower (located at 600 Biscayne Boulevard). It is a great place to expose your kids to the Cuban heritage that is so much a part of life in Miami.

Then you will visit Miami’s Little Havana, and since it’s probably getting close to lunch time, drive yourself to Versailles Restaurant(3555 Southwest 8th Street) in the heart of Little Havana. Then take some time to simply walk the streets and take in the music, the art and the personality of the people and their neighborhood before returning to your car.

On your way back to the hotel, visit the Miami Science Museum, where there are complete science and natural history museums. Or you may visit the Miami Seaquarium (水族馆).Though there are many such theme parks more modern and in better shape than this 1955 pioneer, it’s still worth a visit for their dolphin, sea lion and killer whale shows. Kids can also get face to face with the endangered manatee(海牛)or watch specialists feeding 200-pound sharks.

【推荐3】Located at a depth of 20 feet below the surface, the sand of the ocean floor off the coast of the Florida Keys might be an unlikely spot to host a music festival, but that hasn’t stopped music enthusiasts from diving underwater to rock out.

For the past 35 years, the Underwater Music Festival, an event that pairs music with conservation, has been hosted. Equipped with guitars, drums and other musical instruments, divers go down to the depths and play along to a playlist of water-inspired songs that are piped underwater via speakers. Over the years the event has gone from being a small grassroots effort put together by few locals, with the idea that once people see what’s going on beneath the surface, the more likely they would be to protect it, to a two-day festival that draws dozens of divers, boaters, and musicians to the Keys from around the world.

“Thirty-five years ago a few Keys locals sat down and wanted to figure out a way to bring awareness to our coral reefs （珊瑚礁）that would preserve, rebuild and restore them in any way,” says Dave Turner, executive director of the Lower Keys Chamber of Commerce. “They came up with this idea of playing music underwater and invited people to listen while also enjoying the local sea life.”

“The preservation of the reef is our main purpose,” Turner says. “To avoid any further damage, the festival takes place in a nearby sandy area so that the musicians don’t disturb the coral when they’re performing.”

Although holding a music festival underwater may seem a bit out there, Turner is quick to point out that it is actually achievable. “The music is obviously not as clear as when you’re sitting in room with stereo （立体音响）but you can still hear it and understand the lyrics and music,” he says. “If you were to go underwater you would recognize the song and it would sound the same. It just has little different tone to it. Plus, sound travels faster and farther underwater.”
