Giraffes are beautiful, smart and friendly. They have long legs and necks (脖子). They are so tall that they can grow up over 5 meters (米). So how do they sleep or drink?

    You may think it's difficult for them to sleep, but they have no such problems because giraffes don't often stop for a sleep. Giraffes just need to sleep about thirty minutes a day. When they sleep, they don't always lie down (躺下). They usually sleep for minutes at a time, because it's difficult for them to get up again. And it's a great danger to sleep in the wild (荒野). But the giraffes in the zoo sleep for about 4-6 hours every day. They usually lie down when they sleep.

    Drinking water is a big problem for giraffes because their long necks are too "short". To drink water, they must spread (伸展) their front legs in a difficult way. And in this way, other animals like Africa's big cats can easily hunt (猎食) them. So they usually get most of their water from the trees and flowers. Giraffes don't need to drink water very often. They can even drink no water for months!

Green is an important color in nature. It is the color of grass and the leaves on trees. It is the color of most growing plants, too.

Sometimes, the word green means young, fresh and growing. Sometimes, it describes something that is not yet finished or plants that are not ripe.

For example, a greenhorn is someone who has no experience, who is new to a situation. In the fifteenth century, a greenhorn was a young cow or ox whose horns had not yet developed. A century or so later, a greenhorn was a soldier who had not yet had any experience in war (战争) .By the eighteenth century, a greenhorn had the meaning it has today——a person who is new in a job.

About one hundred years ago, greenhorn was a popular expression in the American west Old—timers used it to describe a man who had just arrived from one of the big cities in the east. The greenhorn didn't have the skills that he would need to live in the hard, rough country.

Someone who has the ability to grow plants well is said to have a green thumb. The expression comes from the early nineteen hundred.

A person with a green thumb seems to have a magic touch that makes plants grow quickly and well. You might say that the woman next door has a green thumb if her garden continues to grow long after your plants have died.

The Green Revolution (革命) is the name which was given some years ago to the development of new kinds of rice and other grains. The new plants produced much larger crops. The Green Revolution was the result of hard work by agricultural (农业的) scientists who had green thumbs.

    Cars make our lives more convenient. But they can also be a problem. For example, fossil fuel (化石燃料) cars mainly cause air pollution.

    To improve the environment, many countries are developing electric vehicles (EVs,电动车). Among them, China is taking a leading role and has created the world's largest EV market.

    Last year, over 40 per cent of the 753,000 EVs sold in the world were sold in China, more than twice as many as the number sold in the United States.

    "Filling up a fossil fuel car with gas (汽油) is more expensive than charging (充电) an electric car," said Wu Hao, who bought an electric car this year.

    However, there are still some problems. It can be hard to find charging piles (充电桩) and the cars can't go far before being recharged.

    Some of these problems are being solved. In 2014, China had 31,000 charging piles. Now China has the world's largest EV charging network, with more than 450,000 charging piles in total.

    Developing EVs is one of many efforts that China has made to cut down pressure on its environment after the government promised to stop increases in carbon dioxide emissions (二氧化碳排放量) by 2030.

    "As China goes, so will the world's car industry," the Wall Street Journal said.

    XBOX 360 Kinetic, RoboSapien, WiiParty, these are just a few of the modern toys sold in recent years. But some of the most popular toys are actually quite old.

Games have been around for thousands of years. In 4000 B. C, Babylonians played a board game that was similar to chess. Yo-yos made of stone were first used in ancient Greece around 1000 B C. And kites appeared in China around the same time.

    Another famous game is Scrabble. It was invented by an architect in the 1930s, but it didn't get popular until 1953 And since then, more than 100 million sets have been sold worldwide.

    As you can imagine, toys and games are a multi-billion-dollar industry. Mr. Potato Head, the first toy advertised on TV, grossed more than $4 million in its first year. Play-Doh made its inventor Joseph McVicker a millionaire by his 27th birthday, while Mattel sells 1. 5 million Barbie dolls each week (that's two dolls each second!).

    Some toys go out of fashion, but then become popular again, such as Rubik's Cube. Research says parents are increasingly choosing to buy toys they remember from their own childhood.

    These days, toys are not just for fun. RoboSapien is a remote-controlled robot that was launched in 2004. He can walk, turn around and do other poses. RoboSapien was designed by Mark Tilden, who once created robots for NASA space missions. He expected the toy to be used mostly by and scientists, but almost 2 million RoboSapiens have been sold worldwide since its launch as a toy?

    Fancy a game anyone?
