A descent of 120 feet is represented by-120. The table shows the submersible's depth after various numbers of minutes.1. Write two different addition sentences that could be used to find the submersible's depth after 3 minutes. Then find their sums.展开更多

The conclusion of this paper will present some possible solutions to these problems.展开更多

Culture Mode is hereby proposed The mode proposed is consisted of two parts: the compilation of reading materials and the reform of teaching process. An action research is conducted and interview is held to explore the efficacy of it to stimulate the students' interests in writing by reading crossculturally, to develop their writing skills by recording their daily life or their observation of the society, to cultivate their critical thinking by writing responses after each session of practice.展开更多
