Both are needed, because the Guide to English Vocabulary for Test Preparation is aimed at the comprehensive ability test of English translation, while the Examination Manual of Common Words in English Translation (Level 2.3 General) is aimed at the actual test of English translation. These two exams, one in the morning and the other in the afternoon, need careful preparation and are relatively difficult to practice.

The CET-3 translation test includes two subjects: comprehensive ability in the morning and translation practice in the afternoon. The examination time is two hours and three hours respectively. The full marks of both subjects are 100%, and the passing system of 60 points is adopted. You can pass the exam only if you have reached 60% or more in both exams.

Comprehensive ability is divided into three parts: lexical grammar selection, cloze and reading comprehension.

The reference books that should be used when preparing for CATTI three-level translation are as follows:

For English-Chinese translation and comprehensive subjects:

1, eight words of New Oriental College.

2. New Oriental-GRE Dictionary of Reverse Memory.

3, Liu Yi 5000 words, 10000 words series.

4. Fan Jiacai's three-dimensional English vocabulary.
