This paper makes a tentative research into shall + notional verb type of sentences in the Constitution of the United States, mainly from the perspective of Dowty s event-based thematic Proto-roles with the help of WordSmith to verify the frequency of the words and phrases introduced by shall.

Generally speaking,if there is a notional verb at the end of a ZUO phrase,the ZUO should be ZUO(DO);if ZUO means "be" or "act as" in a ZUO phrase,the ZUO should be ZUO(BE).

Though there are lexical verb ellipsis and operator ellipsis in both languages,lexical verb ellipsis appears more frequently in English than in Chinese and verbal ellipsis is often used in dialogue in Chinese.

Thus we reclassify Chinese VP ellipsis into three categories and the three categories that we propose in this thesis include: the shi construction, the modal verb construction and the content verb construction.

In the natural and fluent English,the zero stress is more common than the other two,but the zero stress of the content words is often overlooked.

This article sets out to examine the discourse_organizing power of semi_content words in the English language.

In the light of Hoey\'s theory of lexical repetition,investigation into the impact of magnitude of bonds,repetitions of lexical items and grammatical items in the compositions of CET-6 held in Dec 2007 on their quality is conducted.
