Task: Sentiment Analysis
Input (English): If you know English well and you need only to review some important details, this is the book you need to buy. It covers small rules, which are VERY IMPORTANT for the TOEFL, but it does not tell you much, for example, about sequence of tenses.In other words, this book will help you to improve your score, but it can not teach you English if you are a beginner.For me, the most important part of the book was structur review. IT really helped! Listening part shows the same level of difficulty as in the TOEFL, but reading is much easier then on the test. To understand the reading level of difficulty and to practise the test I would recommend TOEFL Test Preparation Kit.
Output (English): Positive
