They are becoming a reality in many parts of the world. A smart home uses the Internet of Things (IoT) to connect different devices in the house, such as lights, door locks, air conditioning and cameras. These devices can communicate with each other and be controlled from anywhere using a smartphone or computer. One of the biggest advantages of smart homes is convenience. For example, you can turn on the lights or adjust the temperature before you get home. If you forget to lock the door, you can lock it with a tap on your phone. Smart home devices can also help you save energy. Lights and air conditioning will turn off automatically when no one is in the room. Safety is another important benefit. Smart cameras can send you a warning if they see something unusual, like a stranger at the door. Flood sensors can detect water leaks and turn off the water supply to prevent damage. For elderly people living alone, smart devices can even call for help if they have an accident. However, smart homes are not perfect. They depend on the Internet, so if the network goes down, some devices may stop working. There are also worries about privacy, as smart devices collect a lot of personal data. To keep the home safe, people need to use strong passwords and update their devices regularly. 1. What is the main idea of the first paragraph? A. The history of smart homes B. How smart homes work C. The disadvantages of smart homes D. The future of smart homes 2. Which of the following is NOT mentioned as an advantage of smart homes? A. Saving energy B. Being convenient C. Keeping people safe D. Making houses cheaper 3. What problem do smart homes face according to the passage? A. They use too much electricity B. They are too difficult to use C. They depend on the Internet and may have privacy problems D. They can be easily broken by strangers 4. What can we learn from the passage? A. Smart homes will replace traditional homes completely soon B. Smart home devices cannot work without the Internet C. All people are worried about the safety of smart homes D. Smart homes can help elderly people who live alone 四、完形填空（共 10 小题，每小题 1 分，共 10 分） 阅读下面短文，掌握其大意，然后从各题所给的 A、B、C、D 四个选项中选出最佳选项。 The Internet of Things (IoT) is changing the way we live.

They can also detect when a street is empty and dim the lights to save energy. Smart traffic lights can change their timing based on the number of cars, which reduces traffic jams. 2______ Smart waste management systems use sensors in rubbish bins to tell the city when they are full. This helps rubbish trucks collect waste only when needed, saving fuel and reducing pollution.
