Exploring the differences in phonemes and cross-linguistic influences, particularly by comparing the pronunciation patterns of English and Mandarin, is crucial for language learners. Such comparative studies can help learners better understand and overcome the pronunciation difficulties encountered during second language acquisition. English and Mandarin have significant differences in their vowel and consonant systems, tones, intonation, and syllable structures. A deep understanding of these differences allows learners to engage in targeted pronunciation training, reducing accent interference. This research provides guidance for improving language teaching methods, enabling teachers to design more effective pronunciation strategies and exercises based on the students’ native language backgrounds, thus enhancing learning outcomes. Additionally, cross-linguistic studies aid in improving speech recognition and conversion technologies, achieving higher accuracy and naturalness in multilingual speech processing systems. From a cultural exchange perspective, understanding and respecting the phonetic characteristics of different languages help to enhance the effectiveness and mutual understanding in cross-cultural communication. The comparative study of English and Mandarin pronunciation patterns not only provides a theoretical foundation for language education and technological applications but also promotes effective communication in multilingual environments. This thesis uses a comparative research method to elucidate the study of English and Mandarin pronunciation patterns. It begins with an analysis of the characteristics and similarities of the pronunciation patterns in both languages. The thesis then examines the differences between English and Mandarin pronunciation patterns through four aspects: the number and complexity of vowel phonemes, types and distribution of consonant phonemes, tones and stress, and intonation and phonetic phenomena. Finally, based on the comparative analysis of the differences, the thesis offers targeted policy recommendations for learning English and Mandarin. 展开更多

Carnivorous fish have poor tolerance to carbohydrate in feed and low utilization rate of carbohydrate.Therefore,the balance of carbohydrate and lipids in the nutrient metabolism of carnivorous fish,the ef fective conversion and utilization of carbohydrate and lipids,and the feedback regulation of feeding are the key links for the e fficient utilization of carnivorous fish feed.Carbohydrate response element binding protein(ChREBP)is a new transcription factor found in recent years in the glucose signaling pathway,and can also participate in feeding regulation.We performed in-vivo and in-vitro experiments to reveal the role of ChREBP in the glucose metabolism and feeding in mandarin fish.The mRNA expression of ChREBP and appetite regulatory factors were measured after intraperitoneal injection of glucose in mandarin fish Siniperca chuatsi and cotransfection with glucose and glucose+siRNA in the hypothalamic cells in mandarin fish.The results reveal that at hour 2 and 4 post intraperitoneal injection with 1 mg/g BW glucose,the blood glucose level of the mandarin fish increased significantly,but food intake decreased significantly,and it also displayed a significantly increased ChREBP mRNA expression levels in liver.At hour 4 post injection,hypothalamic ChREBP mRNA level was significantly increased,whereas the mRNA expression levels of appetite genes neuropeptide Y(npy)and agouti-related peptide(AgRP)were decreased significantly.When the glucose concentration was 40 mmol/L,the expression level of ChREBP mRNA in mandarin fish hypothalamic cells was significantly up-regulated,but the expression level of appetite gene npy mRNA was down-regulated.When siRNA and glucose were co-transfected into mandarin fish brain cells,the expression level of chrebp mRNA was significantly decreased,and the appetite gene npy mRNA was significantly increased.The results indicated that glucose regulated food intake through the modulation of appetite gene npy by ChREBP. 展开更多

Mandarin在(pinyin:zài)is the most frequently used character in representing spatial and temporal relationship.Current studies mostly focus on its lexical meaning and syntactic structure while cognitive features of its grammatical categories have been neglected.This paper investigates into the categorization of zài by conducting a morphosyntactic test among College English majors in China.The results show that:prototypes are organizing the grammatical categories of zài at all levels in terms of intra-categorial gradience;the semantic construal of zài construction could significantly influence the accuracy of the grammatical categorization of zài;the syntactic structure can provide viable cue for the identification of grammatical categories of zài;spatiality,temporality and the status of existing are three essential semantic features encoded by zài,the concurrence of which leads to various degree of inter-categorial vagueness,indicating a conflict between the rigid grammatical classification and the indeterminate nature of the grammatical functions of zai,suggesting the necessity to reconsider the efficacy of applying indiscriminately the Anglo-Saxon grammar into the study of Chinese spatial-temporal constructions. 展开更多

Objectives To develop a set of monosyllable audiometry test material that can be used in speech recognition testing in Mandarin Chinese. Materials and Methods In an effort to improve reliability and efficiency in clinical practice, a set of 30 test lists of 25 monosyllable test items each was designed with consideration of the following: length of the list, phonemical balance (PB), word utility frequency, coverage of common words, and equivalency among lists. The 30 lists contained 750 monosyllabic words and were constructed on the basis of Chinese phoneme distribution probability summarized in the Manual of Acoustic. The occurrence incidence of the 22 consonants, 36 vowels, and 4 tones of the Chinese Mandarin characters in the 30 test lists were calculated. To achieve PB, 489 monosyllables were selected from the 2500 most commonly used Chinese characters and the 4000 most commonly used Chinese phrases to compile the 30 monosyllable test lists using a computer algorithm with manual adjustment. Results Thirty phonemical balanced word lists of common Mandarin Chinese monosyllabic words were compiled. Each list consisted of 25 monosyllables. A total of 489 phonemes (consonants, vowels and tones) were included in the set. Conclusions This set of lists can potentially be used as the basic lists for future development of Mandarin PB monosyllable speech test materials. 展开更多

Objective:The paper discusses recent evidence on the assessment of language outcomes in children with hearing loss acquiring oral language. Methods: Research emphasizes that language tests must be specific enough to capture subtle deficits in vocabulary and grammar learning at different developmental ages. The Diagnostic Receptive and Expressive Assessment of Mandarin (DREAM) was carefully designed to be a comprehensive standardized Mandarin assessment normed in China's Mainland. Results:This paper summarizes the evidence-based item design process and validity and reliability results of DREAM. A pilot study reported here shows that DREAM provided detailed information about hearing impaired children's language abilities and can be used to aid intervention planning to maximize progress. Conclusion: DREAM represents an example of translational science, transferring methods from empirical studies of language acquisition in research environments into applied domains such as assessment and intervention. Research on outcomes in China will advance significantly with the availability of evidence-based comprehensive language tests that measure a sufficient age range of skills, are normed on Mandarin speaking children in China's Mainland, and are designed to capture features central to Mandarin language acquisition. 展开更多

Gamma irradiation mutagenesis is a technique commonly used to induce seedlessness in citrus fruits. We compared fruit quality traits of eight different seeded mandarin varieties within the Israeli citrus breeding collection with those of their corresponding gamma-irradiated low-seeded mutants. The mandarin varieties compared were: “Rishon” with “Kedem”;“Michal” with irradiated “Michal”;“Merav” with “Meravit”;“Vered” with “Vardit”;“Ora” with “Or”;“Murcott” with “Mor”;“Shani” with irradiated “Shani”;“King” with irradiated “King”. Mutational breeding by gamma irradiation reduced average fruit seed number by 70% - 92%. Furthermore, mutational breeding by gamma irradiation delayed ripening of the early-season mandarin varieties “Rishon” and “Michal” by 8 - 13 days, but did not delay ripening of most mid- and late-season varieties. Gamma-irradia- tion mutagenesis also reduced fruit weight of seven of the eight tested low-seeded varieties by 6 - 41 g per fruit. Gamma-irradiation mutagenesis had variable effects on biochemical composition and nutritional quality, in that some irradiated clones presented no changes whereas other had either higher or lower levels of juice total soluble solids, acidity, vitamin C and total antioxidant activity. Finally, sensory evaluations by a trained panel revealed that the flavor of most of the low-seeded, gamma-irradiated varieties was slightly or significantly preferable to that of unirradiated varieties. 展开更多

The Pilgrim’s Progress in Mandarin translated by the British missionary William Chalmers Burns in the 1860s is regarded as one of the typical representatives of the early Europeanized vernacular texts.Compared with the ancient vernacular,the frequency of the inclusive usage of“wǒmen”has increased significantly,which is directly influenced by the plural usage of first-person pronoun in English.Tracking back the origin of Chinese Europeanized grammar is an important part of the study of modern Chinese grammar,which not only is helpful to have a clear understanding of the characteristic of Europeanized grammar in the pre-development stage of modern Chinese,but also can lay a certain foundation for the comparative study of Europeanized grammar in different periods.In addition,this study can also provide linguistic basis for investigating the influence of western missionaries’Chinese translation on the formation of new literature. 展开更多

Six-year Statuma mandarin (Citrus unshiu Marc. Cv. Miyagawa Wase) trees were used as materials to investigate the effects of plastic film mulching on quality and appearance of Statuma mandarin fruit during three periods of cell division, cell enlargement and mature stages. The results showed that mulching during the cell division and early-mature stages increased total sugar and reduced sugar content of fruit as well as the Vc content, compared to the control. However, the titratable acid content, fruit size, peel weight and single fruit weight were all lower than the control. Film mulching during the cell division phage resulted in higher edible fruit rate, while the fruit shape index was similar to the control. Mulching during the early-mature stage didn’t affect the edible rate of fruit, but caused lower fruit shape index. Compared to the control, film mulching during the cell enlargement period caused lower total and reducing sugar content, titratable acid content and edible rate, while the Vc content was a little bit higher than the control. In addition, the fruit size, peel weight, single fruit weight and fruit shape index were all lower than the control. Mulching during the early-mature period effectively enhanced the content of total and reduced sugar and Vc and decreased the titratable acid content. Hence, it increased fruit quality but had negative effect on fruit appearance. 展开更多

The effectiveness of Co-60 gamma irradiation in controlling citrus red mite(Panonychus citri McGregor)had been proved in our earlier work.However,whether it could be used as an alternative method to replace the current way of quarantine treatment against citrus red mites depends on the performances of effective doses on citrus fruits.This study was conducted to explore the effects of Co-60 gamma irradiation on the nutrient composition of citrus(Shatang mandarin);selected fruits were divided into different groups and each group was irradiated at 0.0,0.2,0.3,0.4,0.5,and 0.6,respectively.And then the treated fruits were stored at 4◦C and the nutrient composition was studied in the following days.The results showed that the shelf-life could be extended when fruits were irradiated in the dose range of 0.2–0.4 kGy,while most unirradiated citrus decayed by 15 d.It also turned out that the citrus irradiated at 0.5 and 0.6 kGy were fully decayed within 45 d of refrigerated storage.The content of total soluble solids(TSS),total sugar,ascorbic acid(AA),and titratable acidity had no significant differences compare to those of the control during the 15 d storage period.Nevertheless,the activities of peroxidase(POD)and superoxide dismutase(SOD)decreased after 15 d;the improvement of storage quality and shelf life may be explained by the change of the protective enzyme activity.In conclusion,the results of citrus fruit treated with irradiation at a certain dose indicated the potential use of Co-60 gamma irradiation as a safe quarantine treatment.©2014 Beijing Academy of Food Sciences.Production and hosting by Elsevier B.V.All rights reserved. 展开更多

Since the 1970s, outcome studies for children with hearing loss expanded from focusing on assessing auditory awareness and speech perception skills to evaluating language and speech development. Since the early 2000s, the multi-center large scale research systematically studied outcomes in the areas of auditory awareness, speech-perception, language development, speech development, educational achievements, cognitive development, and psychosocial development. These studies advocated the establishment of baseline and regular follow-up evaluations with a comprehensive framework centered on language development. Recent research interests also include understanding the vast differences in outcomes for children with hearing loss, understanding the relationships between neurocognitive development and language acquisition in children with hearing loss, and using outcome studies to guide evidence-based clinical practice. After the establishment of standardized Mandarin language assessments, outcomes research in China's Mainland has the potential to expand beyond auditory awareness and speech perception studies. 展开更多
