【简答题】
Whether you like it or not, tests are a way of checking your knowledge or comprehension. You may have noticed that tests can be classified into different types according to different testing goals. For example, the purpose of your final examination in school is obviously different from that of IELTS or CATTI. Please state at least 4 types of tests and explain their different functions. Your writing should be no less than 150 words. (直接回答在答案框中,不要上传word文档)
