Everyone who wants to acquire Chinese language when they study in qualified Mandarin program should firstly have better understanding on Chinese words, especially those similar words. 均匀and 平均are a group of similar words that the foreign students should tell apart. The former means the things are spread equally, stressing the well-distributed things in number or the time interval. You may often hear people say 数量均匀and 呼吸均匀. It can be functioned as adverbial modifier and complement.

In addition, 开发and开采are also important for the foreign students to distinguish in meaning. The former word has the meaning of discovering, developing and making use of the new resources or fields after research and efforts like开发新能源and 开发山区. When you learn Chinese online free, you may know it implies to take advantage of the talents or technology like 开发新技术. However, 开采has a narrower application scope which is only used in excavating the mineral resources. Therefore, we often say 开采石油 and 开采煤炭.

具有and具备is a group of common words but difficult to distinguish. 具有means you have something, the existing things, mostly use in the abstract things. The objects of it are usually the confidence, ability, level, style, meaning and quality like 具有深远的历史意义.

However, 具备indicates that you possess something or are equipped with some conditions. When using this word, those who learn to speak Chinese should know the objects can be the abstract thing like condition and ability as well as the concrete things. For example, 我们已经具备了制作风筝的各种材料. Another example that is helpful might be目前条件还不具备，不能盲目生产.
