As far as undergraduate thesis is concerned, pure language research is very difficult in theoretical knowledge reserve and corpus collection, so it is not advisable to advocate it. This paper can be used in language structure (pronunciation, grammar, vocabulary, discourse, etc.). ), language use (unique language phenomena, language means, language changes, etc. ), language culture (the influence of culture on language understanding, use and learning, etc. ).

Comparison of two languages and application research in other fields. The focus of applied research is how to put forward, analyze, demonstrate or solve various new problems in practice by using existing knowledge, and make conclusions with reference or application value.

The application of Spanish

As the second largest language in the world, Spanish is spoken by about 437 million people, mainly in Latin American countries. Spanish is also one of the official languages of the African Union, the European Union and the United Nations.

With frequent exchanges between China and foreign countries, Spanish translation is becoming more and more important. In general, the important standard of Spanish translation is to make the content more appropriate, and we should consider not only the expression of Spanish, but also the translation standard of Chinese.
