Problems and Countermeasures of Cultivating Autonomous English Learning Ability in Vocational Colleges based on Informationization

With the advent of 5G era,it has become an inevitable trend to drive educational modernization with educational informationization.The modern-day education uses science and technology as well as culture in cultivating independent learning as the ultimate goal.However,there are many drawbacks in the system and practical aspects of higher vocational education in which one of it is that the independent learning has been neglected in the learning process.This article analyzed the issues in the autonomous learning of the English language among higher vocational college students and discussed strategies to improve their autonomous learning ability based on informationization to promote bidirectional interaction between teachers and students,cultivate students'consciousness of lifelong learning,improve teachers5 technical skills,and perfect the development of a connotative system in higher vocational colleges.

ON ALGEBRAIC SOLUTIONS OF THE SECOND-ORDER COMPLEX DIFFERENTIAL EQUATIONS WITH ENTIRE ALGEBRAIC ELEMENT COEFFICIENTS

The main purpose of this paper is to study the problems on the existence of algebraic solutions for some second-order complex differential equations with entire algebraic function element coeifficients. Several theorems on the existence of solutions are obtained, which perfect the solution theory of linear complex differential equations.

A Study of Idiom Teaching from the Perspective of Conceptual Metaphor

As a part of vocabulary learning,the idiom is an important part of language teaching.This study is to investigate whether conceptual metaphor can promote idioms’teaching and learning or not.In the course of study,we make use of a combination of qualitative and quantitative analysis,collecting data through the questionnaire survey and do experiments in teaching and learning idioms.We get the conclusion:the T value of the experimental group and the control group is p<0.05,the pre-test and post-test values is p<0.05.It is feasible to apply the conceptual metaphor in idiom teaching and learning.

Review of Keeping Vocabulary Notebooks on Vocabulary Acquisition

Vocabulary notebooks relates to a notebook kept by each individual student with the aim of learning and expanding new vocabularies.Such vocabulary learning approach has been advocated for many years,and its advantages have been proved by many language teaching professionals.

The diversity of soil culturable fungi in the three alpine shrub grasslands of Eastern Qilian Mountains

To understand the diversity of culturable fungi in soil at alpine sites, Rhododendron fruticosa shrubland, Salix cupularis fruticosa shrubland, and Dasiphoru fruticosa shrubland of the Eastern Qilian Mountains were selected to investigate. Three methods, including tradi- tional culturing, rDNA internal transcribed spacer （ITS） sequence analysis, and economical efficiency analysis, were carried out to estimate the diversity of soil culturable fungi of these three alpine shmblands. A total of 35 strains of culturable fungi were cultured by dilution plate technique and were analyzed by rDNA ITS sequence. The diversity indices such as species abundance （S）, Shannon-Wiener index （H）, Simpson dominance index （D）, and Pielou evenness index （3） of Rhododendron fruticosa shrubland, Salix cupularis fruticosa shrubland, and Dasiphoru fruticosa shrubland were ranged between 16 and 17, 2.66-2.71, 0.92, 0.95~）.97 respectively. The results showed that the diversity of soil fungi were abundant in these three types of alpine shrub grasslands, while further study should be done to explore their potential value.
