    ①從政府人員組成看,南京政府是一個以資產階級革命派為主體的政府。②從政府頒發(fā)的法令和措施看,這些法令體現了資產階級民主革命的要求,對于發(fā)展民族資本主義經濟、資產階級民主政治和文化教育以及改革社會風氣,都起了積極作用。③從頒布的《中華民國臨時約法》看,憲法體現了三權分立的政治體制,體現了資產階級民主主義的要求,是中國歷史上第一部資產階級民主憲法,具有反封建專制制度的進步意義。(2)從南京臨時政府的內外政策分析南京政府的根本弱點①未徹底地反封建。它沒有采取比較徹底的反對封建主義的措施,特別是對封建統治的基礎——地主階級土地所有制沒有觸動,這樣,南京臨時政府也就不能真正地把廣大人民群眾動員起來,因而缺乏真正的群眾基礎。

    This teaching period mainly deals with grammar “restrictive relative clauses.” To begin with, teachers should lead students to revise what they have learned about the relative pronouns and relative adverbs. And then, teachers move on to stress more special cases concerning this grammar, such as the “preposition+ relative pronouns which and whom” and cases where we can omit the relative pronouns. This period carries considerable significance to the cultivation of students’ writing competence and lays a solid foundation for the basic appreciation of language beauty. The teacher is expected to enable students to master this period thoroughly and consolidate the knowledge by doing some exercises. 1. Guide students to review the basic usages of relative pronouns and adverbs of attributive clauses.2.
