A moderate level of test anxiety will motivate students while a too high or too low level of test anxiety will influence students’ academic performance and their cognitive abilities. Most present researches are focused on secondary school students or on the final exam of a specific school. Few researches on college students and standard tests can be found. Therefore, the researcher took 255 college students as samples to investigate the test anxiety level of non-English majors, their attitudes towards different test tasks (ATDTT) and the correlation between them. The results of the research are as follows: Firstly, the students from non-English majors are at the lower of a moderate test anxiety level in CET-4 and there is no significant gender difference. Secondly, among the four sections in CET-4, students are most positive in writing, less positive in translation and reading, and the least positive in listening. Thirdly, students’ ATDTT in CET-4 are negatively correlated with total test anxiety, cognitive anxiety and emotional anxiety. The researcher hopes this research can offer some help to teachers and students in need.展开更多

One is the design of the "Writing" form; the other is the scoring process. From the discussion the paper comes to a conclusion that the "Writing Test" in CET-4 should be reformed in two ways: the single style of the "Writing" structure should be changed to various styles in design, and the "global scoring" principle used in marking the writing should be changed to "local scoring".

In spite of a series of reforms of CET-4, the negative impact of CET-4 remains intense. Three main reasons are probed into here. Firstly, the objective of CET-4 is ambiguous. Secondly, the test objective does not accord with teaching objective. Finally, test contents do not match well with the practical language use. To improve the present passive state of CET-4, some suggestions are given.展开更多

This is important in cases where the steel decking is discontinuous when it is orientated parallel to the beams. In this case, it is important to demonstrate that the amount of transverse reinforcement required to transfer local forces from the shear connectors can be reduced relative to the requirements of Eurocode 4. The mechanism under study involved in-plane compression forces being developed in the slab due to the restraining action of the floor plate, which was held in position by the peripheral composite beams;while the secondary beams acted as transverse ties to resist the forces in the floor plate that would otherwise lead to splitting of the slab along the line of the primary beams. The tendency for cracking along the center line of the primary beam and at the peripheral beams was closely monitored. This is the first large floor plate test that has been carried out under laboratory conditions since the Cardington tests in the early 1990s, although those tests were not carried out to failure. This floor plate test was designed so that the longitudinal force transferred by the primary beams was relatively high (i.e., it was designed for full shear connection), but the transverse reinforcement was taken as the minimum of 0.2% of the concrete area. The test confirmed that the primary beams reached their plastic bending resistance despite the discontinuous decking and transverse reinforcement at the minimum percentage given in Eurocode 4. Based on this test, a reduction factor due to shear connectors at edge beams without U-bars is proposed.展开更多

The samples were analyzed from the perspectives of transitivity, modality, thematic structure and cohesion. Fisher's Exact Test from the SAS system was used to compare two-sidedly the correct rate and the constituent ratio of these functional usages between two neighboring levels. Statistical results indicate that it is the quality, not the quantity of these functional usages that distinguishes two neighboring levels. The range-finders can basically represent the abstract scoring criteria as far as the four functional systems are concerned. However, the validity of CET-4 writing needs to be improved.展开更多
