The English grammar question bank can reserve a large number of special knowledge points and special categories of questions, which is helpful for English learners. Therefore, we design and verify the application effect of an intelligent question bank system. We construct an English grammar knowledge map, which is used to design the system architecture, including basic layer, data layer, service layer, business layer, and user layer. On the basis of the system structure, the index system of the item bank is established, and the functional modules of the system are designed comprehensively. Finally, we design a system database based on MySQL and give the table of knowledge points of English grammar. In order to verify the performance of the designed English grammar intelligent test bank system, a verification experiment is carried out. The experiment selects the accuracy rate of English grammatical feature extraction, recall rate, convergence, and system configuration accuracy. The experimental results show that the proposed system can extract English grammatical features with higher accuracy, and the recall rate is more satisfactory. Compared with the reference systems, the designed system configuration accuracy is higher.

English Training

A variety of challenges in online training are found in numerous learning environments such as cultural background, accessibility, technology, learning content and so on. In the developed or western societies, the online training has been developing in a stable way for decades, while numerous typical obstacles seem to be visible in developing countries including student support, flexibility, teaching and learning activities, access, academic confidence, localization and attitudes (Andersson, 2008). These difficulties are not excluded in the context of online English training system (OETS) at Ho Chi Minh City Open University (HCMCOU). Although this institution ever makes effort to limit these possible challenges for ages, plenty of impactful issues leading to serious difficulties of OETS also obviously exist. Hence, to fully explore the key factors that cause greater barriers in this training system, a qualitative on traditions of bioghaphy and grounded theory method was applied. The qualitative data is to be collected from the responses on openended questionaire sent for 30 online English majors and indirect interviews with 5 salient learners were also conducted. The findings show that some minor limitations of learners such as negative learning habits, willpower shortage and neglected learning perception lead to greater barriers of online English training.

Power Management Strategy

In this article, a novel system configuration with multiple energy sources is proposed for a hybrid truck in order to reduce fuel consumption and overcome the drawbacks of using a single energy source. The energy-saving characteristics of the hybrid system can be displayed after analyzing its system structure and performances. In order to validate the advantages of this presented system, the dynamic models of the system components are established in a MATLAB/Simulink environment, and initial and improved power management strategies with rule-based algorithms are developed. Then, the hybrid system is simulated based on the models and control strategies over the urban dynamometer driving schedule driving cycle. The simulation results show that the fuel consumption employing the initial power management strategy is 12.49 L/100 km, and there is a significant decrease with around 13.6% based on the improved strategy. The results also verify that the better fuel economy can be achieved by the proposed multi-source system compared to the counterparts under the same operating conditions.

Quantitative models for marine ecosystem-based management are often constrained by availability of observations. Uncertainty about the underlying system structure can affect model estimates and conclusions about the consequences of management actions. Qualitative models can augment model development for decision-making and may provide an alternative to quantitative assessments. We apply qualitative loop analysis to assess the sensitivity of management outcomes to structural uncertainty within the Georges Bank social–ecological system. Loop analysis uses defined positive or negative relationships between system components to provide inference about cascading effects of pressures on components of management interest. We compare the sensitivity of outcomes from two management strategies in four model structures of the Georges Bank system that investigate trophic and socioeconomic model uncertainty. We summarize system responses to perturbation and compare these responses with a set of management objectives. Models with complex socioeconomic structure estimated positive outcomes more often but with less reliability than simpler models. Our analyses demonstrated trade-offs among habitat objectives for two management strategies, as well as uncertainty about the reliability of outcomes, contingent on model structure.

The Relationship

This study takes a new look at the topic of developmental stages in the second language (L2) acquisition of morphosyntax by analysing receptive learner data, a language mode that has hitherto received very little attention within this strand of research (for a recent and rare study, see Spinner, 2013). Looking at both the receptive and productive side of grammar acquisition, however, is necessary for a better understanding of developmental systematicity and of the relationship between receptive and productive grammar acquisition more widely, as well as for the construction of a comprehensive theory of second language acquisition (SLA). In the present exploratory study, the receptive acquisition of L2 English grammar knowledge is studied cross-sectionally within a Processability Theory (PT) framework (Pienemann, 1998, 2005b), a theory of L2 grammar acquisition which makes explicit predictions about the order in which L2 learners learn to productively process different morphosyntactic phenomena. Participants are 72 francophone beginning child L2 learners (age 6–9) acquiring English in an immersion program. The learners’ ability to process six morphosyntactic phenomena situated at extreme ends of the developmental hierarchy proposed by PT was tested by means of the ELIAS Grammar Test, a picture selection task. Overall, the developmental orders obtained through implicational scaling for the six target phenomena agreed with PT’s predictions, suggesting that similar mechanisms underlie the acquisition of receptive and productive L2 grammar processing skills.

Professional Contexts

Acquiring sufficient linguistic proficiency to perform competently in academic and professional contexts generally requires substantial study time beyond what most language programs can offer in the classroom. As such, teachers and students alike would benefit considerably from high quality self-access materials promoting independent learning out of class when possible and, thus, allowing greater social interaction in class when necessary. The present study is a follow-up to Lyddon (in press), in which a concept-based approach to grammar instruction was adapted into a series of computerized modules. As the number of participants in the previous study was insufficient for meaningful statistical analyses of the learning outcomes, the current investigation redressed this shortcoming as well as responded to survey suggestions for several key changes to the pedagogical materials, including provision of more numerous training sentences, more highly elaborated feedback on exercises, and an immediate remediation option. As before, the purpose of the present study was to determine the viability of a computer-based conceptual approach to teaching English grammar. In a quasi-experimental pretest-posttest design, 31 Japanese university English learners of English for Science and Engineering completed a series of self-paced, interactive online tutorials aimed at teaching the concept of grammatical voice. Gains were then measured in terms of improvement in post-treatment grammaticality judgments. While the findings showed the modules to be generally effective, they also suggest important differences in learner understanding of the use of animate vs. inanimate subjects. Thus, additional study will be needed to focus on this particular issue.

In International work environment, TOEIC test (Test of English for International Communication) is one of the factors or qualifications dealing with International communication. The result of TOEIC test becomes the reference on how far someone has the ability in mastering English both in Reading Skill and Listening Skill. Whenever someone is able to reach the standard score of TOEIC test, it can be said that he or she is able to communicate both written and orally. Moreover, he or she is able to communicate in English as well. In this research, the researcher focused on the ability of the lecturers of IKIP Budi Utomo Malang in mastering English, especially Reading Comprehension in TOEIC test. Focus on Reading Comprehension Skill was chosen since many lecturers of IKIP Budi Utomo Malang did not reach the standard score of TOEIC test, thus, they did not pass the TOEIC test. Dealing with mastering of Reading Comprehension skill, the researcher implemented Module which contains of Reading Comprehension knowledge and English Grammar knowledge. This Module was then implemented to help the lecturers of IKIP Budi Utomo Malang to understand those materials easily. In this research, the researcher implemented pre-experimental research by giving pre-test and post-test to the lecturers of IKIP Budi Utomo Malang. This pre-test was used to know exactly the ability of the lecturers in mastering Reading Comprehension before they had been given treatment. Then, the post test was used to measure the effectiveness of the implementation of Module in giving understanding and raising lecturers’ understanding of Reading Comprehension skill. The implementation of Module was able to raise the lecturers’ understanding of Reading Comprehension in TOEIC test, thus, they could reach the standard score in TOEIC test.

The analysis of the frontier issues of the English language teaching method in China is of great guidance for English language teaching. Based on the ontology model of English teaching domain, the knowledge map of English teaching in colleges and universities is constructed by fusing heterogeneous English subject data from multiple sources. Firstly, we obtain domain knowledge from relevant websites and existing documents through web crawlers and other techniques and clean the data based on BERT model; then, we use Word2Vec to judge the similarity between the research directions of characters and solve the entity alignment problem; based on the scientific knowledge map theory, we count the frequency of keywords in each year and analyze them to describe the association and union between keywords. It can explain the current situation and trend, rise and fall, disciplinary growth points, and breakthroughs of ELT. Through keyword analysis, the hot issues mainly revolve around ELT, English teaching, college English, grammar-translation method, curriculum reform, and so forth, to realize the quick query and resource statistics of ELT basic data, in order to promote the subsequent English discipline assessment work to be completed more efficiently.

Unlawful Interference

So far, airport security screening has only been analysed in terms of efficiency, level of service, and protection against any acts of unlawful interference. Screening procedures have not yet addressed the need to limit operator-to-passenger contact. However, the pandemic situation (COVID-19) has shown that it is a factor that can be a key protection for the health of passengers and operators. The purpose of this paper was to analyse the feasibility of reducing contact between operators and passengers in the airport security screening system by process management with respect to the power consumption of the system. Experimental research was conducted on a real system. A computer simulation was applied to estimate system performance and power consumption. The paper identifies the important findings that expand upon previous knowledge. The results showed that there are two key factors: the experience of operators and proper system structure. These factors can significantly reduce the number of operator-to-passenger contacts and, in parallel, provide lower energy consumption of the system. The results obtained in this article showed that proper management improves the process by up to 37%. This approach expands the World Health Organization’s policy of prevention against COVID-19 and helps to ensure sustainable process management.
