1、1,English Rhythmic Structure The variety of syllable types is more limited; Vowel reduction in unstressed syllables is unlikely.,5,Lloyd James likens stress-timed rhythm to Morse code signals (long dashes and short dots) and syllable-timed rhythm to “machine gun” or staccato patterns (1940).

3、racteristics of stress-timed languages (Dauer 1983, Ramus et al. 1999). In stress-timed languages, stresses are heard as occurring at equal intervals in time (isochrony); in syllable-timed languages, the time between stresses is more variable. However, instrumental measurements reveal that stresses

34、rners: In their speech, it is more often the syllables, instead of the stresses, which tend to come at more-or-less evenly recurrent intervals.

39、up are linked more closely than words across thought group boundaries. Appropriate thought grouping benefits the student in two ways.

40、ke lexical, grammatical, and pronunciation choices (Gilbert 1994, Levis and Grant 2003). Thought groups are both teachable and learnable. It is found that more proficient Chinese learners used pausing more appropriately than less-proficient learners,74,Prepositional Phrases and Infinitives,The core
