【写法借鉴】《科学与艺术》在论证论点的同时，举了许多例子，这些例子都有一个共同点，带有一定的说明性。如“在科学中，人们研究物质的结构，知道所有物质都是由分子、原子构成，原子又都由原子核和电子构成，原子核又由质子、中子组成，质子、中子又由夸克组成等等”。

【片段仿写】议论文中严谨准确的语言，是我们写作时应该学习和借鉴的。请你围绕“破碎”写一段议论性的文字，注意语言要严谨准确。

    Nowadays it's believed that the largest contributors to air pollution are gasoline vehicles. They not only give off harmful gases but also dangerous and heavy metal particles（微粒） that can result in environmental dangers. We can't stop using vehicles and thus stop air pollution right away. However, at least we can look for better replacements so that air pollution can be reduced. According to studies, hydrogen （氢）cars prove to be a better replacement for traditional cars.

    A hydrogen car is a vehicle that uses hydrogen as fuel for its engine to work. There are two types of hydrogen cars. The first one is to use hydrogen as a fuel, and the second one is to use hydrogen fuel cells（电池） to provide power for the car. Hydrogen and oxygen react chemically with each other to produce electricity, thus starting the car.

    There are many advantages of hydrogen cars. For example, hydrogen is available in plenty. Therefore, you needn't worry about a lack of hydrogen. More importantly, no harmful gases are released as by-products .The only by-products are water and a little amount of heat so air pollution is prevented up to a large extent.

    However, there are also some problems with hydrogen cars. For instance, in case of damage, the cost of repairing and replacing fuel cells is high. Worse still, hydrogen is a material which can burn easily, so it can result in a huge explosion of the car.

    The concept of hydrogen cars is relatively new for most people. Research is still in progress to reduce disadvantages and increase advantages. Therefore, hydrogen cars are expected to contribute their bit towards making this planet better and healthier!
