The interlanguage Chinese ESL students develop while acquiring English presents a unique set of challenges for both teachers and language learners. All students working to acquire a second language (L2) incorporate, as part of their learning process, an interlanguage.
Much like the word suggests, an interlanguage is an intermediate language that students develop between their native language (L1) and the target language (L2). When students are in the process of learning a L2, they are using a language that is not the L1 or the L2, but a third language. This interlanguage has its own grammar, its own lexicon, its own phonetic rules, etc. Chinese ESL students develop an interlanguage that reflects the differences between Chinese and English and highlights the specific challenges they face in acquiring English.
English is a language with a very complicated verb system. Important information in English is performed by auxiliaries and by verb inflections.
Chinese, on the other hand, is an uninflected verb language, meaning that other aspects of the language like word order and adverbials carry out this information.
Also, verbs do not handle the concept of time in Chinese the way they do in English through the use of past and present tenses. Combined with the irregular verbs English uses (I go, I went, I have gone, I will be going), the issue of verb tense is particularly challenging for ESL students whose L1 is Chinese.
Proficiency in consonant production in Chinese ESL students depends greatly on the student's consonant production proficiency in their L1. How students pronounce the four sounds of "r" in Mandarin ([r]/[?], [z]. and [l]) foreshadows how well they will acquire the skills to pronounce English /r/.
For most Chinese ESL students, inter-vocalic pronunciation of /r/ as in the word "hairy" develops easier that word-initial /r/ as in rabbit or post-vocalic /r/ as in car.
In addition, students tend to be able to produce consonant sounds with a higher proficiency when reading a list of words than when telling a story or orally reading a narrative.
One of the fundamental differences between Chinese and English is that Chinese is a tonal language. This means that by altering the pitch of a phoneme sound, a speaker can change its meaning. In English, changing a phoneme's pitch doesn't change its meaning, but rather is a technique used to express emotion and enthusiasm.
Factoring in the fact that English has more vowel sounds than Chinese does creates a complicated scenario for Chinese ESL students. The high front lax vowel sound in a word like "bit" will often sound like "beet" and the high back lax sound in "put" will often sound like "poot."
Diphthongs also tend to be shortened to one sound in the Chinese language learner's interlanguage. The low central back-gliding diphthong as found in a word like "crowd" is typically shortened to one sound.
Unlike the English language, Chinese does not use articles and the interlanguage spoken by students reflects this. These language learners often omit or misuse articles, and this issue is one that tends to linger until the later stages of L2 proficiency. The reason for this lies in the fact that article omission typically doesn't interfere with the conveying of meaning in the same way that other aspects of the English language do.
For example, the sentence "I need to bring note from doctor" can be easily understood as "I need to bring a note from the doctor." If, however, the same sentence was phrased "I need to bring story from pharmacist" the vocabulary issues would prove to be more problematic than the misuse or omission of articles. Since any language's primary function is to facilitate communication, those who are learning a new language learn the most crucial aspects first.
Simplification and generalization are inherent traits of any interlanguage. Chinese ESL students are no exception. At the lexical level, general words are substituted for particular words. For example, big rock might be substituted for boulder and horse might be used to describe a donkey or a zebra. At the discourse level, ESL students have difficulty mastering the social contexts in which to use a certain expression or colloquialism.
Chinese and English are very different languages from two different language families. English features a very complicate verb system, the use of articles, and consonant and vowel challenges that all create difficulties for Chinese ESL students. By understanding how the interlanguage is developed by Chinese ESL students provides both students and teachers with specific tools to move continually towards L2 proficiency.
