【答案解析】
I think it is good news that some universities use original English textbooks in their teaching of some specialized courses. It can bring great benefits to students. On the one hand, students can learn some up-to-date science and technology which develope very quickly. Sometimes when they are translated into Chinese, things have developed and changed greatly. On the other hand, by using original English textbooks, students can improve their English reading and listening comprehension ability in English. As a result, it will be easier for the students to pass their English exams. Of course, it may be a great challenge for some students who are poor in English at the beginning. But through hard and long working students can improve their English quickly.
Using English textbooks to teach is demanding for teachers. Because, as I know, nowadays very few teachers are able to teach in English. Many of them cannot express their ideas in English, not to mention teach students. So teachers should improve their English first before they use original English textbooks.
