科普类文章是中考英语的常考题材，每年中考都有所涉及，这类文章的总特点是：科技词汇多，句子结构复杂，理论性强，逻辑严谨。

解题时要注意：

1. 平时多阅读科普知识类文章，学习科普知识，积累常见的科普词汇。

2. 要熟悉科普文章的结构特点。

科普类文章一般由标题、导语、背景、主体和结尾五部份组成。标题是文章中心思想高度而又精辟的概括，但根据历年的中考命题情况来看，这类阅读理解材料一般不给标题，而要求选择标题。导语一般位于文章的首段。背景交待一个事实的起因。主体则对导语概括的事实进行详细叙述，这一部分命题往往最多，因此，阅读时，要把这部分作为重点。结尾往往也是中心思想的概括，并与导语相呼应，命题者常常在此设计一道推理判断题。

3.在进行推理判断时，一定要以阅读材料所提供的科学事实为依据，同时所得出的结论还应符合基本的科普常识。

NO1.---未来的汽车

On a sunny day last January, people got together at a parking lot in Las Vegas to see small vehicles that looked more like colorful eggs than ordinary cars. These vehicles were electric, ran on two wheels instead of four and held only two passengers. Thanks to their tiny size, six of the vehicles would fit in a parking spot. If the idea of parking such a small car makes you nervous, don’t worry: these cars can park themselves. And they can return to their owners when controlled by a button on a cellphone.

The vehicle is called the EN-V(Electric Networked-Vehicle). It is built by General Motors, or GM, arid it points to what future vehicles might be like. It is designed to be energy-saving, solve environmental problems and help ease traffic jams, parking and safety concerns. The automaker says its next concept car(概念车) will help drivers get whatever they want. According to GM, the company has also designed an electric vehicle named Lean Machine. However, it is a small three-wheeler and this single-seater vehicle looks like a motorcycle. One day, such small, electric vehicles might safely carry people around，especially in crowded cities.

Scientists and engineers are finding new ways to make cars safer, smarter and more efficient, or use less energy. New cars may help you keep track of your health by reminding you to take medicine. If it’s elec tric, your car may send you a message reminding you to recharge it. Cars will talk to other cars, your computer, your phone and your iPa d. They’ll help drivers save energy, watch out for other drivers and avoid walkers on the streets.

This is the future of vehicles: safer, smarter and more energy-saving. Besides, they might even drive themselves down the highway or through a city. You can sit back and enjoy the ride.
