For any language，No matter whether its form is rich or not，bet365 sports is essential。Although the bet365 sports of some languages ​​is relatively fixed，The bet365 sports of some languages ​​is relatively flexible，But anyway，bet365 sports plays an important role in language expression。Therefore，Learners when learning a second language，Everyone will inevitably encounter bet365 sports problems。Learners already have corresponding native language bet365 sports strategies when learning a second language，Theoretically，The bet365 sports strategy of the mother tongue will have a certain impact on the acquisition of second language bet365 sports。But just like scholars criticize the shortcomings of comparative analysis，We cannot simply judge the influence of mother tongue bet365 sports based on similarities and differences in bet365 sports，A detailed investigation must be carried out from a typological perspective，Only in this way can we truly find the bet365 sports commonalities that have an impact on second language bet365 sports acquisition，To examine the development process of second language bet365 sports acquisition more comprehensively。

　　bet365 sports typology provides theoretical basis and research perspective for acquisition research。Joseph H. Greenberg’s 1966 study based on bet365 sports universal theory，Created contemporary linguistic typology，Which is generally recognized by the academic community。More than half a century，The language sample for linguistic typology research continues to expand，From the initial 30 to thousands now，Greatly strengthens the explanation that bet365 sports implies commonality。The implication universal theory provides a solid theoretical foundation and analytical framework for language contrast in second language bet365 sports acquisition research。Judging from the current research results on the commonality of bet365 sports，The dominant bet365 sports can appear in harmonious and discordant bet365 sports combinations，But inferior bet365 sports can only appear in harmonious bet365 sports combinations。Implication universal theory and labeling theory are actually connected，Therefore it can be concluded that the dominant bet365 sports is unmarked，The inferior bet365 sports is marked；Harmonious bet365 sports combinations are unmarked，Discordant bet365 sports combinations are marked。Research findings on second language acquisition using marking theory，In second language acquisition, unmarked items always have greater transfer ability than marked items，or influence。That is，If the target language is dominant or harmonious bet365 sports，It is easier for learners to learn，bet365 sports strategy that does not transfer to native language；When the target language is in inferior or discordant bet365 sports，It will be more difficult for learners to learn，It is very likely to transfer the bet365 sports strategy of the mother tongue；If the learner’s mother tongue and target language both have marked bet365 sports，They may choose the third common phenomenon of unmarked bet365 sports。Therefore，Examine whether the learner’s mother tongue and target language have dominant bet365 sports or inferior bet365 sports，It is very important whether the related bet365 sports combinations are harmonious or disharmonious。These are precisely the research results of bet365 sports typology，Can be directly applied to the Institute of Second Language Acquisition。

From the perspective of bet365 sports parameters，In S、V、O parameter on top，Most Chinese languages ​​conform to SVO bet365 sports，But there are also some SOV word orders，English is a typical SVO language，Korean is a typical SOV language。On the preposition (Pr)/postposition (Po) parameter，Chinese has both prepositions and postpositions，English only has prepositions，Korean only has postpositions。Also，in quantifier、Referring to another word、adjective、Possessive language and nouns，Pre/postpositions、Adverbs and verbs，Adverbs and adjectives，Many bet365 sports parameters such as main clause and subordinate clause，Chinese and English、There are complex relationships between differences and similarities in Korean languages。For English native students and Korean native students，Different bet365 sports parameters have different advantages and harmony，The influence of their mother tongue is also different。From a large number of studies，There are still many phenomena in Chinese that do not conform to Greenberg’s 45 bet365 sports commonalities，It is a rare special case among the world language bet365 sports types。So for the bet365 sports phenomenon in Chinese that violates the commonality of language，English、What kind of performance will Korean native language students perform when acquiring？This is a second language acquisition research question triggered by the examination of bet365 sports types。Visible，bet365 sports typology may also become a trigger for second language acquisition research。

In addition，The "discriminability leading principle" and the "semantic proximity principle" proposed by Mr. Lu Bingfu based on the study of language typology are used to deal with various bet365 sports phenomena，Especially some seemingly special bet365 sports phenomena in Chinese，Both have strong explanatory power，To help students overcome difficulties in acquiring Chinese bet365 sports、It is very helpful to master the bet365 sports rules of Chinese。The problem that teachers need to solve is how to apply these principles to the teaching of Chinese bet365 sports。

　　The core issues in the research on foreign students’ Chinese bet365 sports acquisition.Core issues in respective research on Chinese bet365 sports acquisition，It is their construction process of bet365 sports at different levels such as Chinese phrases and sentences。Take English-native students and Korean-native students as examples，There are complex similarities and differences between the mother tongue and Chinese in many bet365 sports parameter settings at different levels，The markings are also different，There are therefore differences in the construction process of bet365 sports strategies between the two types of students when acquiring Chinese。Research on the construction of Chinese bet365 sports strategies cannot only see which Chinese bet365 sports errors students have made，We should pay more attention to students’ understanding and output of different word orders in Chinese，Thus revealing the dynamic development and change process of students’ acquisition of various Chinese word orders。In the selection of research methods，We use a method that combines spoken language tracking corpus and questionnaire testing: the spoken language tracking corpus is collected through weekly free conversation recordings，No topic limit，Freely produced by students，And the corpus collection density is high，You can conduct micro-change analysis to examine the output and dynamic changes of Chinese bet365 sports for the two types of students；The questionnaire test is conducted by sorting words into sentences，To test students’ understanding of different word orders，Especially in the spoken language tracking corpus, the output is relatively small，And bet365 sports without output。This data is used as a supplement to the corpus data，You can see the difference between students’ comprehensible output and natural output。Combining two research methods，Comprehensively infer the detailed process of constructing Chinese bet365 sports strategies for students with different bet365 sports types。In our research on bet365 sports acquisition, we also focused on the two aspects of strategy construction for two types of students。

First, the two types of students’ processing strategies for different interfaces/interfaces。bet365 sports changes in any language involve processing at both the semantic and pragmatic levels，That is, syntax-semantics and syntax-pragmatic interface: sequential changes in syntactic form reflect different semantics，As in "The guests are coming" and "The guests are coming"；At the same time, changes in bet365 sports are also affected by pragmatics，It will also produce different pragmatic effects，As in "repeated battles and repeated defeats" and "repeated defeats and battles"。Some scholars such as Yuan Boying pointed out the syntax-semantics in Chinese acquisition、Syntax-pragmatic interfaces are not difficult points that cannot be mastered，The amount of information processed is an important factor affecting acquisition。Then，What are the problems students with different bet365 sports types encounter when processing interface information in different Chinese word orders？For example, when you need to deal with the syntactic-semantic interface，When to deal with syntax—pragmatic interface，And what strategies they use to deal with these interface obstacles，These are all research problems that must be solved。

The second is the adjustment strategy for the two types of students’ bet365 sports cognitive principles。The driving force behind the differences in bet365 sports between different languages ​​is the logic of each nation、Differences in thinking and cognition，Specifically manifested in distance iconicity、Sequential iconicity、The application of bet365 sports cognitive principles such as quantitative iconicity and marked iconicity。For example，Chinese follows the "from large to small" expression in time and space、The principle of order from near to far，But English follows the completely opposite order principle；The spatial and temporal cognitive order of Korean and Chinese is basically the same，But there are still differences in the specific bet365 sports expression。So，English、The process of Chinese bet365 sports acquisition by Korean native students is accompanied by the adjustment of relevant cognitive principles。The adjustment process of these cognitive principles is slow，And there are cognitive differences in bet365 sports types，Cannot generalize，Need detailed inspection。

　　Pay attention to the interaction between bet365 sports acquisition research and bet365 sports typology.Research on bet365 sports acquisition not only benefits from bet365 sports typology，In reverse，It will also promote the study of bet365 sports typology。For example，Research on bet365 sports typology proves that SVO languages ​​have the largest number，And there is a phenomenon that SOV bet365 sports develops into SVO bet365 sports；At the same time，SVO also has greater compatibility with other bet365 sports parameters，This is reflected in the fact that SVO language contains significantly more word orders of different parameters than other language types。This fully demonstrates the tendency of SVO as a canonical bet365 sports。It can also be found from many second language acquisition studies，It is easier for students with different bet365 sports types to master SVO bet365 sports than other word orders，ie，No matter what bet365 sports type students have, they tend to use SVO bet365 sports when they start learning a second language。The debate between SVO and SOV bet365 sports in Chinese has been around for a long time，From the investigation of this topic, whether it is an English-native student or a Korean-native student，The acquisition of Chinese SVO bet365 sports is also significantly better than the acquisition of SOV bet365 sports。This shows that from the perspective of acquisition and cognition，SVO makes sense as a classic bet365 sports。Students with different bet365 sports types，Especially those students whose native language is different from the classical bet365 sports，Why we acquire and use the same classical bet365 sports？The role of bet365 sports in implying commonality cannot be ignored，Acquisition research has also verified the strength of the explanation that implies commonality。

Then take "If the position changes，Only from the front to the back position" this commonality，Our findings，Whether it is an English-native student or a Korean-native student，They all tend to use "postposition" as the final state of the bet365 sports change，They will also ignore some specific restrictions，The error of directly placing prepositional phrases composed of "in" and "hei" after the verb。The common error tendency of the two types of students shows that this "postposition" bet365 sports commonality also has a strong influence across bet365 sports types。

Acquisition research can reveal the explanatory strength of some commonalities in bet365 sports from the cognitive level。bet365 sports implies commonalities from the perspective of second language learners，Can provide evidence from human cognition for the universality of bet365 sports，Not just reasoning in current language。
