Joseph could express himself in spoken English very well. In our lab’s regular meeting, we always discussed in English in my insistence because I hope they could have more chances to practice spoken English. Also, as I mentioned before, our students need to express themselves in the “Semilar” courses, and most of their graduate courses which were taught in English. When Joseph graduated, he collaborated many famous international companies, including Microsoft, Nokia, IBM. Without great ability of speaking English, he will have no reason to reach the great achievements in coworking with those internations workers.
