The CET-4 argumentative essay has been written into a letter.
Whether it is the college entrance examination or the usual exam, the format requirements are strict, especially the format requirements of letters are more strict. Sometimes, as long as the format of the letter is wrong, half of the points will be deducted, and sometimes even no points will be given. If it is judged as an off-topic composition, it will be a big loss. If you take the college entrance examination, the marking teacher will deduct a little less, accounting for at least one-third or one-quarter of the composition score. It is hoped that candidates will carefully examine the questions and write a good composition as required in order to get high marks.
