A Study on Differences between Children’s First Language and Adults’Second Language Acquisition

Children’s first language(L1)acquisition is generally regarded as natural and effortless.However,adults’second language(L2)acquisition is rather painstaking.The assumption of innate universal language properties,the Universal Grammar and Language Acquisition Device,is proposed to explain the phenomenon of children’s ease in L1 acquisition.The Critical Period Hypothesis or Sensitive Period Hypothesis is also suggested.In terms of the differences in the processes of children’s L1 and adults’L2 acquisition,the following differences are presented:age,motivation,environment,and content.Meanwhile,interference to adults’L2 acquisition is also discussed.

The L2 Acquisition of English Passive

Passive voice is an important grammatical category in language learning while it varies in different languages.In order to diminish the negative impact on L1 transfer and maintain the originality of passive voice in L2 learning,this essay centers on the grammatical differences of passive voice both in English and Chinese and propose practical teaching strategies.

Fast acquisition of L2C CL codes based on combination of hyper codes and averaging correlation

This paper provides a direct and fast acquisition algorithm of civilian long length（CL） codes in the L2 civil（L2C） signal. The proposed algorithm simultaneously reduces the number of fast Fourier transformation（FFT） correlation through hyper code technique and the amount of points in every FFT correlation by using an averaging correlation method. To validate the proposed acquisition performance, the paper applies this algorithm to the real L2C signal collected by the global positioning system（GPS） L2C intermediate frequency（IF） signal sampler—SIS100L2C. The acquisition results show that the proposed modified algorithm can acquire the code phase accurately with less calculation and its acquisition performance is better than the single hyper code method.

On Variables Affecting L1 Transfer in L2 Acquisition

This paper focuses on variables affecting L1 transfer in L2 acquisition, which, according to the author, are categorized into three groups： learner-related variables, language-based variables and socio-linguistic variables, and each of them is clarified in more details.

An Analysis of the Influential Factors in L2 Acquisition

A Review of Research on L2 Vocabulary Acquisition through Reading

The crucial role of lexis in both first and second language acquisition has long been acknowledged by researchers.With that notion, many researchers and instructors has paid much attention to L2 vocabulary acquisition. The paper here attempts to give a brief review of some related research and is supposed to spark some ideas about L2 vocabulary acquisition on a theoretical and pedagogical basis.

Second Language Vocabulary Acquisition through Extensive Reading:Pedagogical Implications of Vocabulary Research

A great deal of L2 vocabulary is indeed learned through extensive reading,which could contribute to solving the beginner's paradox.In extensive reading,the vast majority of vocabulary can be learned gradually through repeated exposures in various discourse contexts.Direct instruction of vocabulary cannot possibly account for the vast growth of students'vocabulary.Consequently,teachers should promote extensive reading because it can lead to greater vocabulary growth than any program of explicit instruction alone ever could.Make sure that students should be preoccupied with relevant background knowledge and have great interest in chosen materials.In this paper,the technique of semi-extensive reading is also developed to help learners balance contextual guessing with dictionary use.Furthermore,at the end of this paper,some pedagogical implications are also given.

The Contrary Effect of Collaborative Writing on ESL Students＇ Vocabulary Acquisition

Writing task is an integral part of education in ESL （English as a Second Language） at the foundation level. It has been observed that foundation level 3 students of Arab Open University have an insufficient knowledge of vocabulary which is reflected on their writing, as their usage of vocabulary is confined to a number of limited common words. This research explores the effect of collaborative writing on students＇ vocabulary acquisition. All the writing tasks were related to educational topics in order to provide students with the lexical items related to the same subject. This study took place in one of the foundation level 3 classes at Arab Open University, Oman branch. Fourteen anonymous Arab students for whom English is considered as the second language participated in this study. All students are in the intermediate level of English language proficiency. For each writing task, five collocations were selected to be taught in the class over a period of five weeks. The achieved outcomes revealed contrary results to the previous studies that had shown the effective impact of collaborative writing. This study has discussed the contrary impact of collaborative writing on improving the learners＇ vocabulary acquisition in addition to the challenges students faced during collaborative writing task. Finally, this research provides recommendations for the effective collaborative writing in the foundation students＇ language proficiency.

The Acquisition of Speech Acts and Pedagogical Implications

Correlational Study between the Information on English Middle Construction and Chinese EFL Learners'Acquisition of English Middle Construction

Less is known about the role that the information input may play in the acquisition of EMC,as such,the influence of the information input remains to be scrutinized.The present study,via quantitative analysis,aims to make a distinctive contribution to exploring this process.Four kinds of information on the six target English middle verbs were adopted:constraints on NP,constraints on AP,examples and all information on EMC.The results show that under the same conditions,examples can meet the demand of user's productive ability in a better way and help improve the production of the EMC.These findings are very informative for second language teaching and provide certain enlightenment for bilingual dictionary compilation.

Studying Language Learners＇ Cognition： Perspectives in L2 Teaching

This paper investigates one aspect of the processing perspective in L2 （the second language） learning： the processing of new words. The article does not try to offer a comprehensive overview of language acquisition mechanisms, but rather it intends to review more narrowly how our conceptual systems, governed by intricately linked networks of neural connections in the brain, make language development possible, at the same time creating some L2 processing problems. Vocabulary acquisition and application has been one of the main issues in English as a Second Language （ESL）/English as a Foreign Language （EFL） learning and teaching research. EFL instructors in Bosnia and Herzegovina, in particular, are coping with the effective vocabulary teaching approaches. The current paper will examine three principles based on cognitive linguistics （CL）, namely the study of categorization, prototype, and metaphor, and applications of these principles in formal vocabulary instruction in a Bosnian context of English learning in Bosnia and Herzegovina.

The Influence of L1 Mental Lexicon on L2 Mental Lexicon

This paper deals with the influence of L1 （first Language） mental lexicon on L2 （second Language） mental lexicon with Chinese subjects. It proves two possibilities： the response types in L1 and L2 of a single individual may be similar, and the dominant language （mostly L1） and the L2 may interfere with each other＇s vocabulary depth and breadth. The result is of great significance for Chinese learners of English.

Fossilization in L2 Learners

In the areas of second language acquisition, fossilization is one of the significant and popular topics that many research?ers have argued for. With decades of study on this topic, there exist a lot of uncertainties and hypotheses from definition to de-fos?silization. This essay mainly focuses on complicated causes for fossilization.

A Study on Developmental Pattern of a L2 Learner's Motivation

This thesis attempts to find out the the learner's L2 attitudinal and motivational changes through the time of learning.This thesis employs qualitative approach to analyze the data collected from the interview. Based on the analyses, it shows that L2learner's motivation does not stay relatively stable but rather evolutes over time.

An Investigation of Two Ways of Teaching Vocabulary to L2 Learners

As for language learners, vocabulary acquisition is one of the most important tasks, and the same goes for L2 teachers.Recently, some researchers claim that semantic mapping is far more effective in vocabulary. The present study comparatively investigate two strategies of teaching vocabulary to non-English lower-intermediate learners. One is the traditional grammatical description and drilling way, the other is the semantic mapping. Six new words were taught by using these two ways respectively,and a sample test was applied to check students' mastery of these words at the end of the class. The test results show that there is no significant difference between the learning outcomes of these two different teaching approaches, but learners turned out to be more engaged when the teacher conducted the semantic links teaching method. Therefore, perhaps, a combination of these two approaches would be a good choice for those L2 learners.

The Use of Cognate Words and Interlingual Homographs to Investigate the Cross-Linguistics in Second Language Processing in Iran

Various investigations have shown that the native language impacts foreign word recognition and this influence is adapted by the dexterity in the normative language. Cognates, words which area like beyond two or additional languages in some fields signify an attention-grabbing, illuminating, and crucial facet of foreign or second language learning and research. Forty-five （males and females） participants have been randomly chosen and participated in the experiment in Islamic Azad University, Zanjan, Iran, in 2014-2015 school year. The participants＇ age was between from 18 to 28, with a mean age of 21.5 years. The materials were divided into two groups which include 30 true cognates and 30 false cognates words from 300 words by doing CVR （content validity ratio） and CVI （content validity index） （Lawshe＇s table with index of 88% and 82% respectively） for being reliable and valid. These words have been taught to them, after a week, a test has been prepared about those words. According to the results of T-test for comparing the average marks of learning in every two groups can be said that there is a meaningful difference between the scores. The results show that the students learned true cognate words better than the false cognate words. The results of this investigation conjointly make sure the expectations that cognate-based instruction can absolutely impact in second language acquisition.

An Analysis of the Influence of Motivation on Learners’Learning Outcomes Based on the Bilingual Motivational Self-system

With the deepening of the understanding of second language learning, we have made a deeper exploration of the factors that affect the learning effect of learners. Among them, motivation, as the influence factor second only to academic technology, has been widely concerned by scholars at home and abroad. Dörnyei put forward the theory of second-language motivation self-system in 2005;the two-language motivation self-system mainly consists of three components, namely, the ideal two-language self, should be two-language self, and second-language learning experience.
