【文章內(nèi)容簡(jiǎn)介】 bage6．閱讀理解 Have you noticed your life being a little easier? Now, when you go to a certain shopping mall, you can enjoy its free WiFi there. When you want to take a taxi, you can book one with your phone. In fact, all these can be seen as the basic parts of a smart city. The idea of a smart city was brought up by US pany IBM in 2010. Generally, a smart city is a city that uses digital technologies such as the Internet to improve city planning, save money and resources, and make our life convenient. How smart can a city be? Here are great examples that we can learn from. In 2009, Dubuque became the first smart city in the US. The city used smart water meters to take the place of traditional water me tens. They can detect （探測(cè)） water waste and leakage （泄漏） and send data to let the house owner know. The same system is used for other city resources like electricity and natural gas. In this way, people know how they use their resources and are glad to help reduce waste. Santander in Spain also gives us a look at the future. If people point a phone toward a nearby bus stop, the phone immediately shows all bus lines that serve the stop as well as their arrival times. The government organized a research team and provided an App （應(yīng)用程序） that collects data on almost everything: light, temperature, and the movements of cars and people.

Every day they are very busy trying to make money for my schooling. One day, my mother was sewing a quilt（縫被子）.I silently sat beside her. Mom, is there love between you and Dad?

What birds can live above it? These questions are difficult to answer, aren39。t they? In fact, the sky has no color. Then why does the sky look blue? We know that there is air around the world. When planes fly, they need air to lift their wings. Planes can39。t fly very high. That is because the air gets thinner when they go higher. The same will happen to us if we go high enough. If we go up about 1, 200 kilometers from the earth, we39。ll find no air there. Some birds can fly into the sky as high as a plane, but they cannot fly or live without air. Looking up above us, you will see the blue sky with white clouds. It is usually light blue. The color would be bluer when you see on the top of a high mountain. And you will see fewer clouds in the sky between you and the sun. Sometimes the sky doesn39。t look blue. When the sun rises and falls, you will see red, orange, and other colors in the sky. Such are the most beautiful moments of the day. Who can see the colors of the sky high above the earth? The astronauts! They can see those beautiful colors of the sky from the outer space. However, before flying into outer space, they sit in a spaceship high above the earth, and there is no air at all. The sky would be that dark and its color would be black. Now you may understand that we see colors because the air scatters（使散射） the sunlight. light travels through the air. Without air, there would be no light or colors. （1）Planes can39。t fly as high as possible because_________. A.the sky is blueB.the wings are heavierC.the sky has no colorD.the air bees thinner（2）When you stand on the top of a high mountain, you will see_________. A.more airB.the bluer skyC.more colors16
