She is our Mother Earth.April 22 is Earth Day. The theme of this year is “Green Cities”.A green city is a healthy and pleasant place for people to live, according to the United Nations. A green city can get its energy from regenerative sources like solar (太阳能的) and wind power. Also, it is connected by clean public transportation. Moreover, a green city is made up of facilities (设施) that can save energy and reduce waste.Around the world, many cities and countries have done well to build themselves in a green way. Chicago is well known for its green roof (屋顶) program. These roofs are covered with plants. The plants get a great amount of rainwater. Later, the water evaporates (蒸发) to help make the air cool and clean. So far, there are about 360 green roofs in Chicago, according to the US Environmental Protection Agency.Curitiba, Brazil, has great transportation. It opened the world’s first bus rapid transit (BRT) system in 1974.BRT runs on special lanes. This makes sure that buses are on time even in traffic jams. With the help of BRT, the city has the lowest level of air pollution in Brazil. Today, many other countries have copied BRT, including China and Mexico.Singapore is home to the first zero-energy building in Southeast Asia. Zero energy means a building is able to create more energy than it uses. Zero-energy buildings work with solar panels (板) mainly on roofs. These panels can make electricity which powers the buildings. By 2030, Singapore plans to build 80 percent of its buildings like this.5. The theme of Earth Day this year is “ _______”.A. Green RoofsB. Green CitiesC. Reducing and RecyclingD. Environmental Protection6.

A spaceman needs a strong body and mind. See here what spacemen are able to do. They have many abilities that may make you amazed. Do you still have a long way to go?Spacemen are able to live upside down (头朝下地). They do this not just during sleep, but also when eating and going to the toilet. Before they fly into space, they have lots of practice. Each upside-down training time lasts for 20 days.Spacemen aren’t just spaceship drivers but also machine repairers and scientists. They have to know every part of the spaceship and how it works. If something goes wrong, they must know how to make it work again. Also they do scientific experiments in space.Spacemen know how to live in the wild. They take a knife, a gun and some dye (染料) with them into space. If they land in forests, the knife and gun can protect them from wild animals. If they fall into the sea,the dye can colour the sea water around them yellow. This can help people find them easily on the sea.Spacemen can’t get dizzy (眩晕的). A spaceship is not a plane. When it goes up, the extra gravity force can break people’s bones. Spacemen must have strong bodies for this. They can’t get a headache or be sick. With many things to take c are of, they’ve got no time for sickness.After you have read the passage, please answer the following questions:8.
