      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 hundreds.
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.

A、a young cow or ox whose horns have not yet developed B、a soldier who has not had any experience in war  C、a person who is new in a job D、a man who doesn't have the skills to live in the   country
(2)、The meaning of the underlined word “ripe” in the second paragraph is ________.

A、If there weren't the Green Revolution, we would have no rice to eat. B、The expression “the Green Revolution” appeared several years ago C、Because of the Green Revolution, we have more kinds of rice and other grains D、Agricultural scientists with green thumbs started the Green Revolution.

A Space Hotel Will Open Soon

A Californian company wants to build a hotel in orbit (天体等运行的轨道). The space hotel will open in 2027. It will be able to carry up to 400 people. The space hotel will be shaped like a large wheel, with 24 space pods (舱) around the outside of the 200-meter-wide structure. The pods will be used for restaurants, bars, gyms, rooms for tourists, laboratories for research and so on.

Researchers at Fudan University in Shanghai have made a new type of cloth that can be used as a digital display (数字显示) . Professor Peng Huisheng and his team have spent 10 years trying to make "digital cloth" with a silver-plated yarn (银镀纱) and a kind of thread. The cloth could allow a driver to view a GPS map on their arm while driving. It could also help people communicate better if they have language barriers or disabilities. 

A Gift Box Made from Mycelium

A UK company Seedlip has released (发布) a gift box that uses packaging (包装材料) made from mycelium (菌丝体). Seedlip is working with Magical Mushroom Company to make the packaging. Magical Mushroom adds mycelium to natural materials that farmers no longer need. As the mycelium tries to break the materials down, it grows threads (线) that form a strong and light material that can be used as packaging. And after being used, it breaks down naturally in about 40 days in a garden.

 Most of the planes we see are white. But do you know why the planes are painted like this?

 Actually, white is not their natural color. But there are many advantages(优点) if they are painted white. It is a good way for airlines(航空公司) to protect their plane from sunlight. Another reason is that white paint can reduce (减少) heat and any possible damage(损坏) from sun radiation(辐射). Less heat also means lower cooling cost for airlines. 

 That's not all. The airplane company staff check the plane's surface each day. White paint makes it easier than colorful paints for staffs to find out the cracks on the plane' s surface. Most importantly, safety is a matter that we should pay more attention to. At night or in bad weather, it will become more difficult for the ground monitoring station to see the plane flying in the sky. So white planes can help people reduce this bad effect(效果) when the planes are seen clearly in the special environment. 

 The cost of keeping a plane in the best situation is mainly considered by many airplane companies. Actually, a colorful appearance looks good but is useless. Colorful planes often lose their color after flying for several years. Especially, bad weather, the main reason, will do harm to their appearance. Airlines will have to spend time and money repainting their planes. In order to cut the unnecessary cost, many airlines will paint them in white or keep most of the planes' appearance in white instead of other colors. 

 All in all, the color white is a better choice.
