Most of the flowers in nature are red, orange and yellow. If we have seen a black flower, it's chance in a million.

    People have made a survey to colors of more than four thousand kinds of flowers and discovered that only eight of them are black.

    As we know, sunlight is formed by seven colored lights. The wavelength of each light is also different, so the quantity(量) of heat in each light is also different. Flowers, especially their petals(花瓣), are easy to be harmed by high temperature.

    Black flowers can take in the light of all the wavelengths that make them dry up because of high temperature, so black flowers can hardly resist(抵抗) sunlight. But red, orange and yellow flowers can protect themselves from sunlight by reflecting(反射) the red light, orange light and yellow light, each of which has a large quantity of heat.

    Height is just one of the thousands of features that your genes(基因) decide. In fact, because you have two parents, your genes provide you a height that usually lands somewhere between the height of each parent. If both your parents are tall, then most probably you will be tall, too. But if you have questions about how tall you're going to be, ask your doctor if he or she can help you find it out.

    But genes don't decide everything. For example, eating an unhealthy diet can keep you from growing to your full potential(潜力). Getting plenty of sleep and enough exercise will help you grow to the expected height.

    No doubt you're wondering how fast you should grow. There's no perfect or right answer. Generally speaking, kids grow about two inches(six centimeters) a year between age 3 and the time when they start puberty(青春期).

    Your doctor will know how your growth has been going over the years, how you've been growing up to this point, and what other changes your body may be going through.

    Don't be scared if you seem to have grown a lot in a very short time. Everyone has a growth spurt(高峰) during puberty. The age for starting puberty is about 10 for girls and about 11 for boys. But it can be earlier or later-between 7 and 13 for girls and between 9 and 15 for boys.

    You'll usually begin to notice that you're growing faster about a year or so after your body starts to show the first changes of puberty.

Another Disney princess movie hit theatres on 5th March 2021. But this time the princess doesn't wait for the prince to save her — she is ready to save the world herself. Raya and the Last Dragon, the film shows Southeast Asian culture and Disney's first Southeast Asian heroine (女主角).

The story takes place in a world called Kumandra. Five hundred years ago, the world's dragons died to save humans. But the world breaks up into five states and they fight against each other. Raya, the princess of one of the states, needs to find the last dragon to save the world. On her journey, Raya invites other people to join her and learns to trust others and be more responsible.

Once upon a time, being a Disney princess meant being a damsel in distress(落难女子) in a European fairy tale, but this movie is different, according to the BBC. Raya has no boyfriend, but is a great fighter who is very brave and independent, according to the movie's writer Adele Lim.

Besides Raya, most of the main characters in the movie, including the dragon Sisu, are female. They stand out and depend on(依靠) no one else instead of acting as supporting roles for males. Namaari, once a friend to Raya, is now a dangerous enemy. She is a strong, brave and loyal fighter, just like Raya.

The movie shows "a complicated dynamic(复杂互动) that's still rare in the Disney universe, particularly between women," the Los Angeles Times said.

Many countries have special holidays that celebrate important events in their past. For example, the United Statc s has Independence Day on July 4th. France has Bastille Day op July 14th. And in Chile, they cclebrate the Fiesta s Patrias on September 18th. But Chile doesn't spend only one day celebrating its independence. It is celebrated for at least two days, September 18th and 19th. 

These two official days are referred to as Dieciocho("eighteen, " pronounced dee-cee-oh-cho)because they start on the 18th. September 19th is celebrated as the Day of the Glory of the Armies. It marks the victory of winning the Spanish army in wars. It is also time to celebrate the end of winter, which in Chile appears during July and August, and the coming of summer, which begins in December. Sometimes 26 festivities might go on for an entire week, and many schools and businesses close for that week so people can travel and celebrate with their families. 

How is Fiesta s Patria s celebrated? There are parades, music and dancing, lots of amazing food and drink, and many partics. Most of all, it is a time for Chilcans to cclebrate their culture and customs. Many men and women dress in traditional Chilean outfits. 

Many small towns and cities begin their celebrations with traditional parties called fondas. These fondas feature live cueca music and dancing. Cueca is a type of music from Chile, Argentina, and Bolivia, and is played with guitars, accordions, percussion, and guitarrons (a large bass gutar) La Cueca is Chile's national dance It is one of the most important parts of celebrating Fiesta s Patrias. Everyone can learn the dance quickly. They work in pairs and mimic(模仿) the courting dance of a rooster and a hen. The partners hold hands using a cloth, and they stomp(跺脚)and circle cach other. Couples often compete to sc e who is the best cueca dancer. 

Dicciocho is a great time to visit the country and experience Chilean culture, food, and fun. Just make sure to bring your dancing shoes and your appetite.
