Khoanh tròn vào đáp án đúngcần gấp ạ thank ----- Nội dung dịch tự động từ ảnh ----- Cars and trucks are surely convenient, and most of US couldn't live without them, but they have become very expensive to run and harmful to the environment. Gas prices have been increasing, and carbon-dioxide emissions from cars pollute the environment and contribute to global warming. As a result, hybrid cars and electric cars have been economical and environmentally friendly alternatives to traditional vehicles. They would be a good choice for the near future. Hybrid cars combine two sources of energy such as a battery-powered electric motor and an internal combustion engine. The driver decides which source of power is appropriate for a given journey. Short rides to the grocery store or the post office could use the electric motor, while weekends in the country may require the internal combustion engine. Electric cars run on rechargeable batteries rather than fuel. They are rather quiet on the road. The best thing about them is they cause about 97% less pollution than regular cars. But there are some disadvantages, too. The battery runs out of energy after driving a short distance, and it takes much time to recharge the battery. Electric cars also are expensive. Their batteries are still expensive and wear out in just a few years. - internal combustion engine: động cơ đốt trong - emission (n): sự thải ra - wear out (v): hao mòn 1.
